1 2008-02-19 Eric Blake <ebb9@byu.net>
3 Clean up example on filtering defined symbols.
4 * doc/m4.texinfo (Foreach, Improved foreach): Document another
5 shortcoming in foreach.m4, and improve filter example by using
6 foreach2.m4.
8 * src/main.c (usage): Fix typo.
10 2008-02-18 Eric Blake <ebb9@byu.net>
12 Avoid some magic numbers.
13 * m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)
14 (CHAR_RETRY): Define in terms of UCHAR_MAX.

22 Reported by Ralf Wildenhues.
24 2008-02-16 Eric Blake <ebb9@byu.net>
26 Add regression test for multi-character quote recursion.
27 * examples/foreach2.m4: Use $0 rather than spelling out name.
28 * examples/foreachq2.m4: Likewise.
29 * examples/forloop2.m4: Likewise.
30 * examples/hanoi.m4: Likewise.
31 * examples/trace.m4: Likewise.
32 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
33 (Improved foreach): Adjust dump from file.
35 Stage 15: return argv refs back to collect_arguments.
36 Collect an entire $@ reference at once rather than one argument at
37 a time, outside of quotes (but inside quotes, $@ is still
38 flattened for now). The skip_last field allows concatenation of
39 $@ with other text when collecting arguments.
40 Memory impact: noticeable improvement, due to better reuse of $@.
41 Speed impact: noticeable improvement, due to less parsing.
42 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.

88 test.
89 * tests/modules.at (modules: text): New test.
91 Fix regression in command line -D option, from 2006-08-25.

103 * bootstrap: Install driver, if not already present.
105 2008-02-06 Eric Blake <ebb9@byu.net>
107 Fix security hole introduced 2007-11-23.

120 (M4BUILTIN, M4BUILTIN_HANDLER): Adjust all builtins.
121 (m4_bad_argc, m4_dump_args, m4_macro_call, m4_arg_argc)
122 (m4_arg_symbol, m4_is_arg_text, m4_is_arg_func, m4_arg_text)
123 (m4_arg_equal, m4_arg_empty, m4_arg_len, m4_arg_func)

138 (undivert, traceon, traceoff): Likewise.
139 * modules/m4.h (m4_dump_symbols_func): Likewise.
140 * modules/perl.c (perleval): Likewise.
142 Stage 14b: allow pushing argv references.
143 Push a $@ reference to the input engine in one go, rather than
144 pushing each element. For now, argument collection still gets one
145 argument of a $@ at a time; but the penalties of this patch make
146 it easier to manage $@ efficiently in future patches.
147 Memory impact: noticeable penalty, due to larger struct and O(n)
148 to O(n^2) on unboxed recursion.
149 Speed impact: noticeable penalty, due to more bookkeeping.
150 * m4/m4private.h (struct m4__symbol_chain): Add comma and quotes

159 (m4__arg_adjust_refcount): ...to this new function.
160 (m4_arg_symbol, m4_make_argv_ref, m4_push_arg): Factor...
161 (arg_symbol, make_argv_ref, m4__push_arg_quote): ...to these new
162 helper functions, to add parameters.
163 (m4_push_args): Adjust caller.
164 * m4/symtab.c (m4_symbol_value_print): Likewise.
166 Stage 14a: allow printing argv references.
167 Refactor symbol-value printing code for better sharing, and to
168 allow printing a contiguous text representation of a $@ ref.
169 Memory impact: none.
170 Speed impact: none.
171 * m4/m4module.h (m4_arg_print): New prototype.
172 (m4_symbol_value_print): Alter prototype.
173 * m4/input.c (struct input_funcs): Add parameter to peek_func.
174 (file_peek, builtin_peek, string_peek): Ignore new parameter.
175 (composite_peek): Ignore new parameter, for now.
176 (composite_clean, pop_input): Rework to minimize indirection, and
177 to avoid infinite recursion in next patch.
178 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
179 (m4_arg_print): New function.
180 * m4/symtab.c (m4_symbol_value_print): Update signature.
181 (m4_symbol_print): Update caller.
182 * m4/output.c (m4_shipout_string_trunc): Update comments.
183 * m4/syntax.c (set_quote_age): Require comma as argument separator
184 when dealing with $@ as a unit.
185 * tests/builtins.at (ifelse): Augment test.
186 * doc/m4.texinfo (Changesyntax): Document changesyntax deficiency.
188 2008-01-31 Eric Blake <ebb9@byu.net>
190 Kill hack for M4 1.4.4.
191 * configure.ac (AM_GNU_GETTEXT_INTL_SUBDIR): Delete, now that
192 we require new enough autoconf which in turn requires M4 1.4.5.
194 2008-01-31 Gary V. Vaughan <gary@gnu.org>
195 and Eric Blake <ebb9@byu.net>
197 Depend on new libtool to use non-recursive build.
198 * configure.ac (LT_PREREQ): Bump to alpha release version.
199 (LTDL_INIT): Choose nonrecursive mode. Perform sanity check that
200 installed libtool has correct symbols.

220 2008-01-28 Eric Blake <ebb9@byu.net>
222 Depend on newer autoconf, for testsuite -C dir.
223 * Makefile.am (CD_TESTDIR): Delete, no longer required.
224 (check-local, installcheck-local, clean-local-tests): Use new -C
225 option from autotest.
226 * configure.ac (AC_PREREQ): Bump to 2.61a.347.
227 * bootstrap: Mention new dependency.
228 * HACKING: Likewise.
230 2008-01-27 Eric Blake <ebb9@byu.net>
232 Stage 13: push composite text tokens.
233 Support pushing composite tokens, allowing back-references to be
234 reused through multiple macro expansions. Add hueristic that
235 avoids creating new reference when pushing existing references.
236 Memory impact: noticeable improvement due to better reference
237 reuse, except for O(n) to O(n^2) copying in boxed recursion.
238 Speed impact: slight penalty, due to more bookkeeping.
239 * m4/m4private.h (m4__push_symbol): Adjust prototype.

295 Memory impact: slight improvement, due to smaller struct.
296 Speed impact: slight improvement, due to less bookkeeping.
297 * m4/m4private.h (enum m4__symbol_chain_type): New enum.
298 (struct m4_symbol_chain): Rename...
299 (struct m4__symbol_chain): ...to this, since it is internal.
300 * m4/symtab.c (m4_symbol_value_copy, m4_symbol_value_print): All
301 callers updated.
302 * m4/input.c (struct m4_input_block, m4__push_symbol)
303 (composite_peek, composite_read, composite_unget)
304 (composite_clean, composite_print, m4__make_text_link)
305 (append_quote_token): Likewise.
306 * m4/macro.c (expand_macro, arg_mark, m4_arg_symbol, m4_arg_text)
307 (m4_arg_equal, m4_arg_len, m4_make_argv_ref, m4_push_arg)
308 (m4_push_args): Likewise.

339 Stage 11: full circle for single argument references.
340 Pass quoted strings through to argument collection in a single
341 action, so that an argument can be reused throughout macro
342 recursion if it remains unchanged.
343 Memory impact: noticeable improvement, due to more reuse in
344 argument collection stacks; O(n^2) to O(n) on boxed recursion.
345 Speed impact: noticeable improvement, due to less copying.
346 * m4/m4module.h (m4_arg_text): Add parameter.
347 (M4ARG): Adjust.

367 (collect_arguments): Update new field.
368 (expand_macro): Reduce ref-count of back-references after use.
369 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
370 names.
371 (m4_is_arg_text): Also recognize composite symbols as text.
372 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.

376 (process_macro): Use single-argument references.
377 * m4/output.c (m4_shipout_string_trunc): Update comment.
378 * tests/macros.at (Rescanning macros): Augment test.
380 2008-01-16 Eric Blake <ebb9@byu.net>
382 Stage 10: avoid extra copying of strings and comments.
383 When collecting tokens that are immune to further expansion, avoid
384 copying data from one obstack to another by outputting it into the
385 destination obstack to begin with. Also reduce copying done in
386 format builtin.
387 Memory impact: slight improvement, due to better obstack usage.
388 Speed impact: noticeable improvement, due less data copying.
389 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
390 modules.
391 * m4/m4private.h (m4__token_type): Adjust prototype.
392 * m4/input.c (m4__next_token): Support new parameter.
393 * m4/macro.c (m4_macro_expand_input, expand_token)
394 (expand_argument, collect_arguments): Adjust callers.
395 * modules/m4.c (ntoa): Tighten buffer size.
396 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.

406 2008-01-15 Eric Blake <ebb9@byu.net>
408 * TODO: Update with some newer URLs.
410 Verify linear `index'.
411 * tests/builtins.at (index): New test.
412 (translit): Make test take longer, to make quadratic algorithms
413 more apparent.
415 2007-12-20 Eric Blake <ebb9@byu.net>
417 Stage 9: share rather than copy single-arg refs.
418 Use hooks of previous patch to create back-references to arguments
419 in the input engine, and inline short text rather than always
420 creating a FIFO link. Also start testing embedded NUL behavior.
421 Until the argument collection engine also shares references, the
422 memory usage increases.
423 Memory impact: noticeable penalty, due to longer life of argv
424 changing O(n) to O(n^2) on boxed recursion.
425 Speed impact: slight improvement, due less data copying.
426 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.

433 (expand_macro): Track scratch space per macro call.
434 (m4_arg_scratch): New function.
435 (m4_make_argv_ref): Call new function.
436 (m4_push_arg): Push reference to $0.
437 (m4_push_args): Rework separator usage, since separators will
438 usually be inlined.
439 (process_macro): Allow embedded NUL.
440 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
441 (m4__push_symbol): Add parameter. Inline short strings, and save
442 references through rescanning.
443 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
444 * modules/m4.c (errprint, index): Handle NUL transparently.
445 (dumpdef, translit): Use scratch space, rather than expansion
446 stack.
447 * modules/gnu.c (renamesyms, m4symbols): Likewise.
448 * tests/others.at (nul character): New test.
449 (iso8859): Quote absolute file name, remove XFAIL.
450 * tests/iso8859.m4: Avoid raw NUL in output.
451 * tests/null.m4: New file.
452 * tests/null.out: Likewise.
453 * tests/null.err: Likewise.
454 * Makefile.am (OTHER_FILES): Distribute new files.
455 * .gitattributes: Treat new files as text.
457 2007-12-17 Eric Blake <ebb9@byu.net>
459 Stage 8: extend life of references into argv.
460 Add hooks to lengthen the lifetime of arguments reused in a macro
461 expansion, rather than always discarding arguments at the end of
462 expand_macro. Rework the expand_macro obstacks to handle longer
463 lifetimes. For now, the hooks remain unused.
464 Memory impact: slight penalty, due to larger structs.
465 Speed impact: slight penalty, due to more bookkeeping.
466 * m4/system_.h (obstack_regrow): Delete.
467 * m4/m4private.h (struct m4_symbol_chain): Add level field.
468 (m4__push_symbol): Adjust prototype.
469 (m4__adjust_refcount): New prototype.
470 (DEBUG_MACRO) [DEBUG]: New debug control.
471 (struct m4__macro_arg_stacks): New structure.
472 (struct m4): Add arg_stacks, stacks_count fields.
473 * m4/m4module.h (m4_make_argv_ref): Add parameter.
474 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
475 context->arg_stacks.
476 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
477 conditional on M4_DEBUG_MACRO envvar.
478 (collect_arguments): Adjust signature.
479 (expand_macro): Rework obstack handling.
480 (m4__adjust_refcount, arg_mark): New functions.
481 (m4_make_argv_ref): Populate new field.

483 (process_macro): One less cast.
484 * m4/m4.c (m4_delete): Clean up arg_stacks.
485 * m4/input.c (make_text_link): Use new field.
486 (m4__push_symbol, file_clean): Update signature.
487 (composite_read): Bump refcount when done with reference.
488 (composite_clean): New function.
489 (pop_input): Adjust caller.
490 * m4/debug.c (m4_debug_message): Make assertion match comment.

492 * tests/builtins.at (ifelse): New test.
493 (exp): Move and rename...
494 * tests/others.at (countdown): ...to this.

496 example.
498 2007-12-13 Eric Blake <ebb9@byu.net>
500 Yet more rewording.
501 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
502 the previous patch.
504 * THANKS: Update.
506 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
508 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
509 example.
510 Reported by Giovanni Toffetti.
512 2007-12-11 Eric Blake <ebb9@byu.net>
514 Stage 7: use chained input support in input parser.
515 Allow the LIFO input engine to rescan a macro expansion composed
516 of smaller chunks of FIFO data, rather than the old approach of a
517 monolithic string. For now, all chunks are still copied.
518 Memory impact: slight penalty, due to FIFO chain overhead.
519 Speed impact: slight penalty, due to extra bookkeeping.
520 * m4/m4private.h (m4__push_symbol): New prototype.
521 (struct m4_symbol_chain): Add const-safety.
522 * m4/symtab.c (m4_symbol_value_print): Simplify.
523 (dump_symbol_CB): Update caller.
524 * m4/input.c (struct m4_input_block): Alter u_c member, first
525 introduced 2006-10-25, but unused until now.
526 (composite_peek, composite_read, composite_unget)
527 (composite_print, init_builtin_token): Rewrite accordingly.
528 (m4_push_wrapup): No longer need trailing NUL.
529 (m4__push_symbol, make_text_link): New functions.

532 (expand_macro): Simplify logic of nesting_limit.
533 * src/main.c (main): Likewise.
534 * doc/m4.texinfo (Dumpdef): Augment test.
536 2007-12-08 Eric Blake <ebb9@byu.net>
538 Stage 6: convert builtins to push arg at a time.
539 Add new methods to factor all builtins whose expansion includes an
540 argument, making back-reference creation easier in future patches.
541 Factor out length-limited printing to obstacks, and use -1 rather
542 than 0 for unlimited length.
543 Memory impact: none.
544 Speed impact: slight improvement, due to better code sharing.
545 * m4/m4module.h (m4_shipout_text): Rename...
546 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
547 that does not worry about sync lines.
548 (m4_shipout_string_trunc): New prototype.
549 * m4/output.c (m4_shipout_text): Rename...
550 (m4_divert_text): ...to this.
551 (m4_shipout_string): Move guts...
552 (m4_shipout_string_trunc): ...to this new function.
553 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
554 (expand_token, process_macro): Update callers.
555 * m4/input.c (string_print): Likewise.
556 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
557 Likewise.
558 * modules/gnu.c (patsubst): Likewise.
559 (debuglen): Use SIZE_MAX for unlimited debug length.
560 * src/main.c (main): Likewise.
561 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
562 zero.
564 2007-12-07 Eric Blake <ebb9@byu.net>
566 Minor security fix: Quote output of mkstemp.
567 * modules/m4.c (m4_make_temp): Produce quoted output.
568 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
569 tests.
571 Stage 5: add notion of quote age.
572 Cache the quoting rules that were in effect when a string was
573 parsed, to avoid reparsing that string if no changequote or other
574 quote age change took place in the meantime. A quote_age of 0 is
575 always safe, but does not benefit from caching.
576 Memory impact: slight improvement, due to smaller struct in input
577 engine.
578 Speed impact: slight penalty, due to more bookkeeping.
579 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
580 (m4_set_symbol_value_text): Adjust prototype.
581 (m4_has_syntax): Factor out the unsigned char cast.
582 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
583 quote_age members.

592 (m4_symbol_value_copy): Adjust callers.
593 * m4/macro.c (expand_token): Add parameter, and track quote age.
594 (expand_argument, collect_arguments): Track quote age.
595 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
596 (m4_macro_expand_input): Update callers.

609 callers.
610 * src/freeze.c (reload_frozen_state): Likewise.

614 * examples/wrapfifo.m4: New file.
615 * examples/wraplifo.m4: New file.
616 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
618 2007-12-04 Eric Blake <ebb9@byu.net>
620 Fix builds with OpenBSD make.
621 * Makefile.am (HELP2MAN): New macro.
622 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
623 srcdir.
624 * README: Update copyright.
625 * HACKING: Mention help2man and makeinfo dependencies.
627 2007-11-29 Eric Blake <ebb9@byu.net>
629 Stage 4: route indir, builtin through ref; make argv opaque.
630 Finish making struct opaque to all but the input engine, by
631 reworking obstack usage in expand_macro to better support creation
632 of a $@ reference. Canonicalize the empty argument, to allow
633 pointer comparison optimizations.
634 Memory impact: slight penalty, due to larger struct.
635 Speed impact: slight improvement, due to fewer function calls.
636 * m4/system_.h (obstack_regrow): Fix precedence.
637 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
638 New prototypes.
639 (struct m4_macro_args): Move...

661 Stage 3b: cache length, rather than computing it, in modules.
662 Use cached token length in builtins and output engine.
663 Memory impact: none.
664 Speed impact: noticeable improvement, due to fewer function calls.
665 * m4/hash.c (m4_hash_remove): Avoid double free on remove
666 failure.
667 * m4/output.c (m4_shipout_string): Change semantics of len param.
668 (m4_shipout_int): Use cached length.

676 * m4/symtab.c (m4_symbol_value_print): Likewise.
677 * modules/gnu.c (__file__, __program__, builtin, indir)

689 * tests/builtins.at (mkstemp): Likewise.
690 * tests/others.at (iso8859): XFAIL this test, now that
691 length-based handling allows NUL through part but not all of M4.
693 2007-11-28 Eric Blake <ebb9@byu.net>
695 Stage 3a: cache length, rather than computing it, in libm4.
696 Cache the length of a token in the input engine and symbol table,
697 to avoid repeating lots of strlen calls. Additionally, by using
698 obstack length rather than strlen, the input engine can now
699 support embedded NUL.
700 Memory impact: slight penalty, due to larger struct.
701 Speed impact: slight improvement, due to fewer function calls.
702 * m4/m4module.h (struct m4_macro_args): Cache length.

725 Adjust implementation.
727 2007-11-27 Eric Blake <ebb9@byu.net>
729 Stage 2: use accessors, not direct reference, into argv.
730 Outside of macro.c, use accessor methods rather than direct access
731 into the argv struct.
732 Memory impact: none.
733 Speed impact: slight penalty, due to increased function calls.
734 * m4/m4private.h (m4_arg_argc): New fast accessor.

754 usage.
756 2007-11-24 Eric Blake <ebb9@byu.net>
758 Stage 1: convert m4_symbol_value** into new object.
759 Pass a variable-size wrapper structure instead of an array to
760 builtins, so that subsequent optimizations in the structure need
761 not impact every builtin client.
762 Memory impact: slight penalty, since struct is larger than array.
763 Speed impact: slight penalty, due to increased bookkeeping.
764 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
765 * m4/m4module.h (m4_macro_args): New type, will be opaque to

832 Handle some defn corner cases differently.
833 * doc/m4.texinfo (Defn): Update documentation; although this still
834 doesn't match the branch, since it may be changed before 2.0.
835 * m4/macro.c (expand_argument): Consistently ignore builtins in
836 concatenation contexts.
837 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
839 2007-11-13 Eric Blake <ebb9@byu.net>
841 Note: Patches titled Stage 0 through N form a series of patches
842 which decreases the algorithmic complexity of tail recursion in
843 macro expansions from O(n^2) to O(n) in both time and memory, then
844 performs cleanups, such as handling of embedded NUL, made easier
845 by the code refactoring.
847 Stage 0: Fix memory leak in tail recursion.
848 Free expansion text in the input engine as soon as it is parsed,
849 rather than when the recursive expansion completes.
850 Memory impact: noticeable improvement, due to reduction from
851 O(n^2) to O(n) on recursion.
852 Speed impact: minor improvement, due to better memory usage.
853 * m4/input.c (pop_input): Add flag parameter and return type.
854 (next_char): Adjust caller.
855 (m4_push_string_init): Let go of memory earlier.

1542 M4 was designed to have a small number of header files defining
1543 the interfaces to several source files each. Keeping this in
1544 mind allows us to tidy things up considerably. Having done this,

3605 (m4_regexp_compile): Return an m4_pattern_buffer. Adust all
3606 callers.
3608 2006-07-04 Gary V. Vaughan <gary@gnu.org>
3610 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Update to take into account
3611 changes to gnulib getopt.m4 since last build.
3612 * Makefile.am (src_m4_SOURCES): Only compile shipped getopt module
3613 if the system getopt fails M4_GETOPT tests.
3615 2006-06-22 Eric Blake <ebb9@byu.net>
3617 * Makefile.am (EXTRA_DIST): Distribute gnulib-cache.m4.
3618 Reported by Bruno Haible.
3620 2006-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 * m4/module.c (m4__module_exit): Avoid ltdl memory leak.
3624 2006-06-19 Eric Blake <ebb9@byu.net>
3626 * THANKS: Update.
3628 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3630 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
3631 (clean-local): Split into and depend upon...
3632 (clean-local-tests, clean-local-src): ...these two. The latter
3633 removes the libtool object directory below `src', to work around
3634 a buglet in Automake, failing to list it.
3635 (EXTRA_DIST): Distribute modules/perl.c.
3637 2006-06-19 Eric Blake <ebb9@byu.net>
3639 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
3640 right side of dependency; VPATH does that.
3641 (stamp-vcl): Update to use libtool's algorithm.
3642 (EXTRA_DIST): Distribute stamp-vcl.
3643 Reported by Ralf Wildenhues.
3644 (TESTSUITE): Revert earlier change that used absolute path, as
3645 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
3646 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
3647 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
3648 atlocal takes care of it instead.
3649 (check-local, installcheck-local, clean-local): Inline absolute
3650 path to testsuite here, rather than relative path to testsuite
3651 elsewhere.
3653 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3655 * m4/m4private.h (DELETE): Cast away const here...
3656 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
3657 * src/freeze.c (reload_frozen_state): Avoid uninitialized
3658 variable warning.
3660 2006-06-19 Eric Blake <ebb9@byu.net>
3662 * Makefile.am (doc/m4.1): Build in $(srcdir), to match where
3663 .info pages are built.
3664 Reported by Ralf Wildenhues.
3665 (EXTRA_DIST): Inline definition of testsuite, so that make dist
3666 works again.
3668 2006-06-16 Eric Blake <ebb9@byu.net>
3670 Follow recommendations from autoconf manual for autotest.
3671 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
3672 turn it into an absolute path until autotest provides an option
3673 that allows us to avoid changing directories. Properly quote
3674 throughout.
3675 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
3676 (check-recursive): Delete unused target.
3677 ($(TESTSUITE)): Atomically update testsuite.
3678 (CD_TESTDIR): Simplify.
3679 (m4__cd): Delete unused macro.
3680 (check-local): Let TESTSUITEFLAGS influence the run.
3681 (installcheck-local): Let TESTSUITEFLAGS override
3682 AUTOTEST_PATH. Add dependencies.
3683 (clean-local): Clean up.
3684 (DISTCLEANFILES, MAINTAINERCLEANFILES): Add directory location.
3685 * README: Document how to use the testsuite.
3687 2006-06-15 Eric Blake <ebb9@byu.net>
3689 * configure.ac (M4_DEFAULT_PRELOAD): Fix typo in last commit.
3691 * ltdl/m4/m4-error.m4 (M4_ERROR): Use M4_ instead of m4_ to avoid
3692 clashes with m4sugar.
3693 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Likewise.

3699 * ltdl/m4/debug.m4 (M4_CHECK_DEBUGGING): Likewise.
3700 * configure.ac: Likewise.
3701 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
3702 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
3703 conditional.
3704 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
3706 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
3707 const mpq_t is not assignable from plain mpq_t. Avoid
3708 type-punning warnings caused trying to mix these types.
3709 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
3710 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.
3711 * modules/evalparse.c (or_term, xor_term, and_term, shift_term),
3712 (mult_term, exp_term): Remove type-punning casts.
3713 (numb_pow): Remove const qualifier.
3714 * src/freeze.c (reload_frozen_state): Fix typo in messages.
3715 Fix variables that can be used uninitialized, which fixes
3716 security hole where malicious frozen file can execute arbitrary
3717 code.
3719 2006-06-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3721 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).
3723 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3724 and Eric Blake <ebb9@byu.net>
3726 Allow `make dist' to work again.
3727 * Makefile.am (EXTRA_DIST): doc/helptoman.pl is gone.
3728 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
3729 (cvs-dist): Fix typo.
3730 * NEWS: Match current version number.
3732 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
3735 ltdl.h is used.
3737 * bootstrap: Do not run libtoolize manually, this is done
3738 correctly by autoreconf. Invoke autoreconf with --no-recursive
3739 to avoid unnecessary rerunning of autotools for libltdl.
3741 2006-06-13 Eric Blake <ebb9@byu.net>
3743 * THANKS: Update.
3745 2006-06-12 Eric Blake <ebb9@byu.net>
3747 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
3748 bother with mktemp.
3749 * src/m4.h: Don't declare mktemp.
3750 * m4/input.c (m4__next_token): Avoid bzero.
3751 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
3752 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
3753 than distributing outdated helptoman.pl.
3754 * doc/helptoman.pl: Delete.
3756 2006-06-10 Eric Blake <ebb9@byu.net>
3758 * README (Patches): Document the current dependence on CVS
3759 builds of autotools.
3760 * ltdl/m4/gnulib-cache.m4: Update, and use --macro-prefix=M4.
3761 * configure.ac: Use consistent quoting throughout.
3762 (AC_PREREQ): Bump to 2.59d.
3763 (AC_INIT): Package name begins with uppercase.
3764 (AC_ARG_WITH): Use AS_HELP_STRING.
3765 (AM_INIT_AUTOMAKE): Enable gnits mode.
3766 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
3767 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
3768 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
3769 done by gnulib or automake, or which autoconf has declared
3770 obsolete.
3771 * m4/m4private.h (Includes): Assume C89 or better, and use errno
3772 unconditionally.
3773 * m4/output.c (Includes): Likewise.
3774 * modules/gnu.c (Includes): Likewise.
3775 * modules/m4.c (Includes): Likewise.
3776 * src/m4.h (Includes): Likewise.
3778 * README-alpha: Update web address.
3779 * README: Likewise. Change encoding to ASCII. Remove old advice
3780 about cygwin. Document bootstrapping dependency.
3781 * AUTHORS: Update from branch-1_4.
3782 * THANKS: Likewise. Change encoding to UTF-8.
3783 * BACKLOG: Delete. This file is too old and unmaintained to be
3784 worthwhile.
3785 * ChangeLog: Change encoding to UTF-8.
3787 Avoid compiler warnings.
3788 * m4/macro.c (trace_format): Don't mark this as a printf format,
3789 since we don't accept the same set of modifiers as printf. It
3790 would be nice if gcc let us specify a custom format archetype.
3791 * src/main.c (main): Cast away const.
3793 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
3794 Eric Blake <ebb9@byu.net>
3796 * modules/time.c (ctime): Pass correctly typed variable to
3797 m4_numeric_arg.
3798 (gmtime): Likewise.
3799 (localtime): Likewise.
3800 (strftime): Likewise.
3801 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
3802 limit inherent in this interface.
3804 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
3806 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
3807 (sysval): Use WEXITSTATUS.
3808 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
3809 big-endian and little-endian wait status definitions.
3811 2006-05-06 Eric Blake <ebb9@byu.net>
3813 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
3814 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
3815 in src, not gnu.
3817 2006-05-06 Eric Blake <ebb9@byu.net>
3819 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
3820 subdirectory to use.
3821 (support for -pipe): Move after LT_INIT, since it relies on
3822 libtool internals.
3824 2006-05-05 Eric Blake <ebb9@byu.net>
3826 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.
3828 * THANKS: Update.
3830 2006-05-05 Bruno Haible <bruno@clisp.org>
3831 and Eric Blake <ebb9@byu.net>
3833 * configure.ac (gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES): Move to...
3834 * ltdl/m4/gnulib-cache.m4: ...this new file, per new gnulib-tool
3835 usage pattern.
3836 * bootstrap: Update usage of gnulib-tool.
3838 2006-05-04 Eric Blake <ebb9@byu.net>
3840 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
3841 Cleanup whitespace.
3843 2005-12-05 Gary V. Vaughan <gary@gnu.org>
3845 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
3846 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
3847 Reported by Eric Blake <ebb9@byu.net>
3849 2005-12-04 Gary V. Vaughan <gary@gnu.org>
3851 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
3852 http caching as -C is no longer supported by wget 1.10.x.
3853 Reported by Eric Blake <ebb9@byu.net>
3855 2005-10-20 Gary V. Vaughan <gary@gnu.org>
3857 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
3858 to ...
3859 (iface_id): ...an lt_dlinterface_id type.
3860 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
3861 throughout, instead of calling obsolete lt_dlhandle_find directly.
3862 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
3863 throughout, instead of calling obsolete lt_dlhandle_next.
3864 * m4/m4private.h (m4__module_find): Declare it.
3865 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
3866 Use m4__module_next instead of obsolete lt_dlhandle_next.
3868 2005-10-20 Gary V. Vaughan <gary@gnu.org>
3870 * bootstrap (func_update_po): Update pofiles directly from the
3871 translation project.
3872 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
3873 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
3874 these files under source control anymore.
3875 Suggested by Eric Blake <ebb9@byu.net>
3877 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3879 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
3880 file escaped the address updates on 2005-05-01.
3882 2005-07-07 Gary V. Vaughan <gary@gnu.org>
3884 * bootstrap: Allow user overriding of gnulib-tool location, and
3885 correctly determine module source directories whether gnulib-tool
3886 is given as a relative or absolute path, or is found by searching
3887 PATH.
3888 Reported by Eric Blake <ebb9@byu.net>
3890 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3892 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
3893 and $RM are defined for various versions of
3894 AC_LIBTOOL_COMPILER_OPTION.
3896 * bootstrap (AUTORECONF): New variable to allow user overriding of
3897 autoreconf path.
3899 2005-07-07 Gary V. Vaughan <gary@gnu.org>
3901 * doc/m4.texinfo (History): Add better notes on the ancestory of
3902 GNU m4, and other historical interest.
3904 2005-05-08 Gary V. Vaughan <gary@gnu.org>
3906 * m4/symtab.c (m4_symbol_rename): New function that performs a low
3907 level symbol rename.
3908 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
3909 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
3910 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
3911 regsub...
3912 (erenamesyms, renamesyms): ...builtins that use these to implement
3913 macro renaming by regular expression.
3914 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
3915 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
3916 to stop the new generated tests from choking.
3918 2005-05-07 Gary V. Vaughan <gary@gnu.org>
3920 Since most of the build is handled from a single Makefile.am now,
3921 we can teach make about the dependencies between the m4 binary and
3922 the preopened modules it is built against:
3924 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
3925 preopened modules.
3926 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
3927 of the preopened modules have changed.
3929 2005-05-07 Gary V. Vaughan <gary@gnu.org>
3931 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
3932 have a native implementation.
3934 2005-05-06 Gary V. Vaughan <gary@gnu.org>
3936 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
3937 handled already by gnu/exit.h.
3939 * configure.ac (gl_MODULES): Add assert to support a
3940 --disable-assert configure time option for NDEBUG setting.
3942 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
3943 * bootstrap (src_modules): Add version-etc-fsf.
3944 * src/main.c (version_etc_copyright): Removed.
3946 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
3948 2005-05-04 Gary V. Vaughan <gary@gnu.org>
3950 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
3951 recognition macros.
3952 * src/freeze.c (produce_frozen_state): Use \n line-endings even
3953 on Windows, so that the frozen file reader will work.
3954 Reported by Josef T. Burger <bolo@bolo.com>
3956 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
3958 Forward port of a patch that allowed m4-1.4.2 to compile on
3959 QNX 6.3:
3961 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
3962 sys/signal.h.
3963 * src/m4.h: And include them as appropriate.
3964 * src/main.c, src/stackovf.h: Don't include signal.h literally;
3965 m4.h will include the correct file.
3967 2005-05-04 Gary V. Vaughan <gary@gnu.org>
3969 * m4/m4private.h: Make errno visible for the sources patched
3970 below.
3972 2005-05-04 Paul Eggert <eggert@twinsun.com>
3974 * src/main.c (print_program_name_CB): Preserve errno, since
3975 M4ERROR relies on this.
3976 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
3977 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
3978 * m4/path.c (m4_path_search): Don't let "free" trash errno when
3979 returning NULL.
3981 * m4/output.c (m4_insert_file): Don't assume errno has a valid
3982 value simply because fread returns zero. This fixes a
3983 portability bug reported by Marion Hakanson in
3984 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
3986 2005-05-04 Santiago Vila <sanvila@debian.org>
3988 * tests/stackovf.test: Use tempfile if available.
3990 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
3992 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
3993 * m4/output.c (m4_insert_file): Do not mix buffered and
3994 unbuffered I/O, as this breaks on the Hurd.
3996 2005-05-04 Gary V. Vaughan <gary@gnu.org>
3998 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
3999 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
4000 and libtoolize does a better job of ltdl importing now too, so
4001 take advantage of that while updating the tree:
4003 * acm4, config: Moved from here...
4004 * ltdl/m4, ltdl/config: ...to here.
4005 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
4006 src/Makefile.am, tests/Makefile.am: Removed...
4007 * Makefile.am: ...and migrated to here, with adjustments to
4008 compensate for relative path differences.
4009 * commit: Adjust relative paths.
4010 * configure.ac: Adjust relative paths.
4011 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
4012 patch.
4013 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
4014 the meanwhile, CVS HEAD libtool is needed.
4015 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
4016 stricly new enough, we also need a patch.
4017 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
4018 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
4019 (gl_MODULES): Don't list getopt and version-etc, as they don't
4020 belong in libm4.
4021 * bootstrap: After running gnulib-tool to import the listed
4022 modules, fetch getopt and version-etc into src manually.
4023 (ltdldir): Change to ltdl.
4024 * src/main.c: Adjust for changes in version-etc API.
4025 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
4026 but works when the getopt module isn't to be included in the lib.
4027 * README: Add note about patching autoconf and automake to
4028 bootstrap CVS m4.

4032 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
4033 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
4034 empty file rather than to a nonexistent file. This closes a
4035 common security hole.
4036 * modules/m4.c (m4_maketemp): Implement the above, by using
4037 mkstemp rather than mktemp.
4039 2005-05-01 Gary V. Vaughan <gary@gnu.org>

4076 * m4/system_.h: Likewise, in non-configured includes.
4078 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
4079 Gary V. Vaughan <gary@gnu.org>
4081 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
4082 Protect definitions from macro expansion under -DNDEBUG by
4083 parenthesising the expanded function names.
4084 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
4085 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
4086 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
4087 (m4_is_syntax_macro_escaped): Similarly protect function
4088 definitions from macro expansion under -DNDEBUG by #undefing the
4089 matching macro names before each definition. Also, move all the
4090 function definitions to the end of the file so that any
4091 invocations in the rest of the file pick up the fast macro
4092 versions.
4093 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
4094 (m4_set_debug_file, m4_set_trace_messages)
4095 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
4096 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
4097 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
4098 option setter functions.
4100 2004-09-23 Gary V. Vaughan <gary@gnu.org>
4102 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
4103 to gnu.
4105 2004-09-23 Gary V. Vaughan <gary@gnu.org>
4107 * src/main.c: Include gnulib files from the correct directory.
4109 * gnulib/*: Don't store any of the gnulib files in arch, as they
4110 generate spurious changes.
4111 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
4112 gnulib macros now share our macro directory.
4113 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
4114 * bootstrap: Call gnulib-tool to import from the gnulib tree.
4115 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
4116 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
4117 the gettext macros from autopoint that overwrite the gnulib-tool
4118 imported versions. Import sources and Makefile.am into the `gnu'
4119 directory. Changed all callers.
4120 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
4121 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
4122 for imported modules.
4123 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
4124 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
4125 hardcoding the gnulib macros they wrap.
4127 2004-07-15 Gary V. Vaughan <gary@gnu.org>
4129 Latest CVS libtool can preload modules in libraries, including
4130 its own module loaders! Tweak m4 so that it doesn't try to treat
4131 libltdl's module loaders as m4 modules when freezing and on exit:
4133 * gnulib/acm4/*.m4: Don't store these files in arch since they
4134 generate spurious changes.
4135 * bootstrap: Simplify initial libtoolize call, since CVS
4136 libtoolize is smarter these days.
4137 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
4138 build.
4139 * m4/module.h (m4__module_exit): Missing declaration.
4140 * m4/m4private.h (m4__module_next): New function declaration.
4141 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
4142 encapsulation. Changed all callers.
4143 (m4__module_interface): New function to verify m4 loadable module
4144 interfaces.
4145 (m4__module_init): Register the interface validator.
4146 (m4__module_exit): Only close my own modules.
4147 * modules/m4.c (unistd.h): Provide missing declaration.
4148 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
4149 (m4_expand_ranges): More missing declarations.
4150 * modules/modtest.c (export_test): Ditto.
4151 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
4152 * src/main.c (main): Bump copyright year.
4153 * tests/modules.at: Fix sed syntax error.
4156 2004-06-17 Gary V. Vaughan <gary@gnu.org>
4158 Tweaking to enable compilation with latest CVS libtool and
4159 libltdl. We can't just dump the library files directly into the
4160 m4 directory anymore now that libltdl is built from pieces itself:
4162 * bootstrap: Rewritten to use latest libtoolize sanely, and to
4163 set up libltdl subdirectory.
4164 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
4165 gnulib subdirectory's config.
4166 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
4167 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
4168 macros from gnulib.
4169 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
4170 configure.ac, so use AC_WITH_LTDL instead.
4171 * Makefile.am (SUBDIRS): Add libltdl.
4172 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
4173 gl_INCLUDED_REGEX.
4174 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
4175 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
4176 (libm4_la_LIBADD): Add LIBLTDL.
4177 * m4/ltdl.c, m4/ltdl.h: Removed.
4178 * m4/m4module.h: Include canonical ltdl.h.
4179 * po/*.po: Updated.
4181 2004-06-14 Gary V. Vaughan <gary@gnu.org>
4183 * gnulib/import: Now updates makefile fragments, and configure.ac.
4184 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
4185 * gnulib/m4/Makefile.am: include it.
4186 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
4187 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
4188 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
4189 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
4190 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
4191 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
4192 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
4193 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
4194 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
4195 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
4196 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
4197 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
4198 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
4199 import.
4200 * gnulib/m4/getopt_int.h: New source file from latest gnulib
4201 import.
4202 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
4203 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
4204 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
4205 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
4206 Updated source files from latest gnulib.
4208 2004-02-29 Gary V. Vaughan <gary@gnu.org>
4210 * config/mailnotify: New file for mailing commit notifications,
4211 imported from cvs-utils.
4212 * commit: Updated from cvs-utils and tweaked for m4.
4214 2003-12-01 Gary V. Vaughan <gary@gnu.org>
4216 * config/mkstamp: Updated from CVS libtool.
4217 * configure.ac: Generate a gnu coding standards compliant version
4218 number, and use it for the banner.
4219 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
4220 mhen the TIMESTAMP changes in ChangeLog, but the file modification
4221 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
4222 contain the previous version number.
4223 * src/main.c: Make --version output conform to the GNU standard.
4225 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
4226 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
4227 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
4228 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
4229 time_la_SOURCES): ...so that these are defaulted correctly, and
4230 can be removed from this file.
4231 (AM_LDFLAGS): Add -module...
4232 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
4233 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
4234 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
4235 the individual settings can be removed.
4236 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
4237 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
4238 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
4239 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
4240 time_la_LIBADD): ...so that these are picked up as a deplib of
4241 libm4 and don't need to be set explicitly.
4243 2003-11-18 Gary V. Vaughan <gary@gnu.org>
4245 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
4246 from the standard build. It is too fragile.
4248 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
4249 CVS libtool after merging m4 changes across to libtool.
4251 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
4252 * m4/path.c (search_path_add): Ditto.
4254 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4256 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
4257 libtool tags we don't use in configure. This reduces the size
4258 of the script from over 1Mb to under 700Kb.
4260 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4262 The import script was not written properly, and the last gnulib
4263 import was incomplete. Fixed that problem, and reimport our
4264 gnulib dependencies, which picks up the address calculation
4265 overflow checks described by Paul below. Also tweak the clients
4266 of the gnulib xalloc module not to use deprecated macros:
4268 * gnulib/import: Recurse through module dependencies rather than
4269 naively descending only one level.
4270 * configure.ac: Add calls to gnulib's strnlen and extension module
4271 macros.
4272 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
4273 extension modules.
4274 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
4275 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
4276 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
4277 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
4278 gnulib.
4279 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
4280 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
4281 place of `xcalloc (1, S)'.
4282 * m4/m4.c (m4_create): Likewise.
4283 * m4/m4private.h (m4_symbol_value_create): Likewise.
4284 * m4/symtab.c (symtab_fetch): Likewise.
4285 * m4/syntax.c (m4_syntax_create): Likewise.
4286 * src/freeze.c (reload_frozen_state): Likewise.
4287 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
4288 macro.
4289 * m4/symtab.c (m4_symtab_create): Likewise.
4291 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4293 * tests/module.at: Comment typo.
4295 2003-10-10 Gary V. Vaughan <gary@gnu.org>
4297 * tests/modules.at (modules: importing): Apply some lateral
4298 thinking, and use AT_CHECK to compare the output of a sed pass
4299 over stderr against the canonical strerror string.
4301 * tests/modules.at (modules: importing): Edit the generated stderr
4302 output to canonicalize strerror output, before a comparison.
4304 2003-10-10 Gary V. Vaughan <gary@gnu.org>
4306 Tru64UNIX perl is sloppy with namespace pollution. This patch is
4307 careful not to trip over the mess:
4309 * modules/perl.c: Some builds of perl install headers that contain
4310 `#define try __builtin_try'. Be sure to undefine that macro
4311 before `m4/hash.h' gets included, which uses the `try' symbol.
4312 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
4313 `false' before including `stdbool.h'.
4314 (DELETE): This symbol is not in m4's namespace, and is in any
4315 case only used internally...
4316 * m4/m4private.h (DELETE): ...so move it to here.
4317 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
4319 2003-10-08 Paul Eggert <eggert@twinsun.com>
4321 Don't use XMALLOC and XCALLOC. Once we install the
4322 corresponding patch into gnulib, this will fix some
4323 address-calculation overflow bugs on hosts where calloc (A, B)
4324 returns garbage when A*B overflows.
4326 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
4327 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
4328 xmalloc, XCALLOC with xcalloc.
4329 * m4/m4.c (m4_create): Likewise.
4330 * m4/m4private.h (m4_symbol_value_create): Likewise.
4331 * m4/output.c (m4_output_init): Likewise.
4332 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
4333 * m4/syntax.c (remove_syntax_attribute): Likewise.
4334 * src/freeze.c (reload_frozen_state): Likewise.
4335 * src/main.c (main): Likewise.
4337 2003-10-07 Gary V. Vaughan <gary@gnu.org>
4339 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
4340 gnulib/acm4 directories for aclocal m4 macros.
4341 * gnulib/Makefile.am (EXTRA_DIST): Removed.
4342 (MAINTAINERCLEANFILES): Add Makefile.in.
4343 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
4344 modules we use.
4345 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
4346 * gnulib/import: New file. Temporary script for updating gnulib
4347 imported files, until gnulib-tool is working.
4348 * gnulib/config/codeset.m4, gnulib/config/error.m4,
4349 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

4385 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
4386 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
4387 gnulib/import script.
4388 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

4392 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
4393 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
4394 gnulib with gnulib/import script.
4395 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
4396 guards ready for gnulib-tool to autoupdate on import.

4409 * src/main.c (version_etc_copyright): Only output the current
4410 year.
4411 (version_etc): Call with new variadic API.
4413 2003-09-16 Gary V. Vaughan <gary@gnu.org>

4426 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
4427 Gary V. Vaughan <gary@gnu.org>
4429 * bootstrap: Separate options.
4430 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
4431 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
4432 not set.
4433 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
4434 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
4435 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
4436 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
4437 $(LTLIBINTL) for gettext support on cygwin.
4438 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
4439 have $(LTLIBINTL) from the preloaded module la files.
4440 * README: Remove the warning about using --disable-nls on Windows
4441 machines.
4443 2003-09-15 Gary V. Vaughan <gary@gnu.org>
4445 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
4446 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
4447 is required.
4449 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4451 * doc/STYLE: Document the gnulib header naming conventions, and
4452 #include policy.
4453 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
4454 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
4455 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
4456 respectively.
4457 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
4459 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
4460 module from CVS gnulib.
4461 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
4462 (gl_FUNC_STRTOL): In favour of the module macro.
4464 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4466 Replace the getopt code with CVS gnulib getopt. The source files
4467 detect whether they are in a glibc environment and preprocess away
4468 all of the code if there is a system getopt, so we can compile
4469 them into the m4 executable unconditionally:
4471 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
4472 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
4473 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
4474 macros.
4475 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
4476 version.
4477 * src/Makefile.am: Adjust.
4478 * src/main.c: Always include our shipped getopt.h.
4479 * po/POTFILES.in: Use new location of getopt.c.
4481 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4483 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
4484 * config/Makefile.am: Removed. Automake 1.8 distributes the files
4485 in this directory automatically.
4486 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
4488 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
4489 isn't set yet.
4490 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
4491 inline.
4492 * modules/Makefile.am (pkglibexecdir): Set it here.
4493 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
4495 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
4496 Import regex module from CVS gnulib.
4497 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
4498 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
4499 do extra substitutions for Makefile.
4500 * configure.ac: Use it.
4501 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
4502 from regex_.h if necessary.
4503 * m4/system_.h: Include the correct version of regex.h.
4504 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
4505 version.
4506 * po/POTFILES.in: Use new location of regex.c.
4508 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
4509 realloc.c: automake distributes these files already.
4511 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4513 Replace the xstrzdup code by importing the xstrndup module from
4514 CVS gnulib, along with its dependencies: strndup and strnlen:
4516 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
4517 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
4518 gnulib.
4519 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
4520 gnulib/config/strndup.m4: Ditto wrt strndup.
4521 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
4522 strnlen.
4523 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
4524 However, contrary to gnulib, we install xstrndup.h.
4525 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
4526 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
4527 is an artifact of the old m4 portability layer.
4528 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
4529 * m4/system_.h: Include xstrndup.h.
4530 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
4532 2003-09-11 Gary V. Vaughan <gary@gnu.org>
4534 Reimport the latest xalloc module from CVS gnulib, and adjust the
4535 m4 sources to take advantage of xalloc xfree. Also create a new
4536 macro DELETE with the same semantics as the old m4 XFREE macro,
4537 and carefully tweak callers:
4539 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
4540 gnulib.
4541 * m4/utility.c (xfree): Removed. This function is now supplied by
4542 gnulib xalloc.
4543 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
4544 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
4545 * m4/symtab.c (m4_symtab_create): Ditto.
4546 * m4/system_.h: Removed XFREE redefine.
4547 (DELETE): New macro with same functionality as the original m4
4548 XFREE macro, but based on xalloc.h now. Changed all callers.
4549 * src/main.c (main): Use XMALLOC macro.
4550 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
4551 instead of XFREE.
4552 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
4554 2003-09-10 Gary V. Vaughan <gary@gnu.org>
4556 Import the xalloc module from CVS gnulib, along with its
4557 dependencies: exitfail, malloc and realloc. We had different
4558 semantics for our XFREE and a function xfree() not supplied by
4559 gnulib, so also a bit of work to keep everything running
4560 smoothly:
4562 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
4563 (gl_XALLOC): Use gnulib equivalents.
4564 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
4565 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
4566 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
4567 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
4568 realloc.
4569 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
4570 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
4571 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
4572 imported modules.
4573 (pkgincdir): Removed. Use pkgincludedir instead.
4574 * m4/m4private.h (XFREE): xfree already checks for NULL.
4575 * m4/system_.h: Use xalloc module, and remove macros already
4576 supplied by xalloc.h.
4577 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
4578 moved the old definition from m4/xmalloc.c to here for now.
4580 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4582 Import the error and progname modules from CVS gnulib. Our old
4583 error.c subsumed the functionality of both, so a little adjustment
4584 was required to accomodate the split in sources. Also added more
4585 wrapper macros to choose between a system installed error.h or our
4586 shipped gnulib error module:
4588 * m4/error.c, m4/error.h: Removed.
4589 * m4/Makefile.am: Adjust.
4590 (pkgincdir): Removed. Use pkgincludedir instead.
4591 * m4/module.h, src/main.c: Don't include `m4/error.h'.
4592 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
4593 error.h.
4594 * gnulib/m4/progname.c: Imported from CVS gnulib.
4595 * gnulib/m4/progname.h: Ditto.
4596 * src/main.c: Adjust to use progname module.
4597 * gnulib/m4/error.c: Imported from CVS gnulib.
4598 * gnulib/m4/error_.h: Ditto.
4599 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
4600 if appropriate, and link a local error.h if the system version is
4601 missing.
4602 (libgnu_la_SOURCES) Add progname module sources.
4603 * gnulib/config/error.m4: Imported from CVS gnulib.
4604 * gnulib/config/strerror_r.m4: Ditto.
4605 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
4606 to have ERROR_H for Makefile substitutions and tell system.h
4607 whether the system error.h should be used, or a locally installed
4608 version.
4609 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
4611 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4613 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
4614 s/gettext_.h/gettext.h/.
4616 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
4617 automake have been fixed.
4619 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
4620 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
4621 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
4622 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
4624 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4626 The gnulib obstack module requires the gnulib gettext module for
4627 systems that do not have GNU gettext installed. Because we use
4628 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
4629 that directory incase it clashes with the system gettext.h. This
4630 delta uses gettext_.h and extra rules in the Makefile to make a
4631 link to gettext.h when needed:
4633 * Makefile.am (auxdir): Removed. No longer used.
4634 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
4635 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
4636 moved.
4637 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
4638 Makefile based build.
4639 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
4640 of the macros are kept.
4641 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
4642 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
4643 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
4644 distributes these automatically.
4645 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
4646 warning from automake-1.7a.
4647 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
4648 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
4649 all callers.
4650 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
4651 wrt. m4_FUNC_OBSTACK.
4652 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
4653 wrt. m4_sys_STACKOVF.
4654 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
4655 wrt. _m4_LIB_GMP, m4_LIB_GMP.
4656 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
4657 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
4658 respectively.
4659 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
4660 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
4661 gettext.h link on deficient systems.
4662 (pkginc_HEADERS): Mention $(GETTEXT_H).
4663 (EXTRA_HEADERS): Mention gettext.h.
4664 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
4665 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
4666 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
4667 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
4668 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
4669 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
4670 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
4671 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
4672 gnulib/config/po.m4, gnulib/config/progtest.m4,
4673 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
4674 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
4676 2003-09-05 Gary V. Vaughan <gary@gnu.org>
4678 We can't mirror the gnulib directory structure here, since we need
4679 to be able to eg. `#include <m4/obstack.h>' from our source files,
4680 which is much easier if the local obstack.h is created in a
4681 directory named m4. Rather than trying to symlink everything into
4682 the m4 directory, now we build a libtool convenience library from
4683 the sources we get from gnulib and link that with libm4.la:
4685 * gnulib/config/extensions.m4: Imported from CVS gnulib.
4686 * gnulib/config/unlocked-io.m4: Ditto.
4687 * gnulib/m4/unlocked-io.h: Ditto.
4688 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
4689 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
4690 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
4691 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
4692 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
4693 * m4/Makefile.am: Adjust.
4694 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
4695 macros we redistribute.
4696 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
4697 library among others.
4698 (GNULIB_SRCS, GNULIB_MACROS): Removed.
4699 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
4700 * config/m4-obstack.m4: Adjust.
4701 * po/POTFILES.in: Adjust.
4702 * configure.ac: Reformatting. Call newly imported gnulib macros.
4703 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
4704 bogus calls of `#include "m4.h"'.
4705 * Makefile.am: INCLUDES has been deprecated in favour of
4706 AM_CPPFLAGS.
4707 * m4/Makefile.am: Ditto.
4708 * modules/Makefile.am: Ditto.
4709 * src/Makefile.am: Ditto.
4711 2003-09-05 Gary V. Vaughan <gary@gnu.org>
4713 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
4715 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4717 Migrate the obstack support into the gnulib directories for easy
4718 synchronisation with upstream files in gnulib:
4720 * config/gnu-obstack.m4: Moved from here...
4721 * config/m4-obstack.m4: ...to here.
4722 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
4723 * m4/obstack.c, m4/obstack_.h: Moved from here...
4724 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
4725 * po/POTFILES.in: Adjust.
4726 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
4727 * m4/Makefile.am: Add a whole new section to link the obstack
4728 sources from the gnulib tree if necessary.
4729 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
4730 from gnulib.
4731 * config/m4-obstack.m4: Rewrite as a wrapper for
4732 gnulib/m4/obstack.m4.
4734 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4736 GNU M4 currently builds with a number of files adapted from
4737 upstream sources. Recently the gnulib project on savannah.gnu.org
4738 has pulled together a great many of these externally maintained
4739 files. This delta is the beginnings of isolating those files
4740 maintained in gnulib to make it easy to synchronise M4 with the
4741 upstream files prior to releases.
4743 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
4744 directory.
4745 (SUBDIRS): Added new gnulib subdirectory.
4746 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
4747 * config/stdbool.m4: Moved from here...
4748 * gnulib/m4/stdbool.m4: ...to here.
4749 * m4/stdbool_.h: Moved from here...
4750 * gnulib/lib/stdbool_.h: ...to here.
4751 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
4752 distributed.
4753 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
4754 code to work with new stdbool_.h location.
4755 (gnulib_srcdir): New.
4757 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4759 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
4760 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
4761 builds to work.
4762 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
4763 (EXTRA_DIST): Use it.
4765 * bootstrap: CVS autoreconf leaves file droppings. Remove
4766 aclocal.m4t incase autoreconf doesn't.
4768 2003-08-29 Gary V. Vaughan <gary@gnu.org>
4770 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
4771 the other gnulib imports, renamed to m4/obstack_.h.
4772 * m4/obstack.c: Updated from CVS gnulib.
4773 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
4774 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
4775 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
4776 about vpath already, and $top_srcdir upsets CVS Automake, so the
4777 $top_srcdir reference was removed.
4779 * m4/system-h.in: For consistency with the gnulib imports, renamed
4780 to m4/system_.h.
4781 * m4/Makefile (EXTRA_HEADERS): Adjust.
4782 * configure.ac (AC_CONFIG_FILES): Adjust.
4784 * m4/stdbool_.h: New file from gnulib for systems without their
4785 own.
4786 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
4787 * config/stdbool.m4: New file. Macros from gnulib for same.
4788 * configure.ac: Use it.
4790 2003-08-27 Gary V. Vaughan <gary@gnu.org>
4792 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

4843 ac_default_headers is an autoconf internal variable.
4844 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
4845 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
4847 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
4848 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
4849 delta.
4851 2003-08-15 Gary V. Vaughan <gary@gnu.org>
4853 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
4854 C99 bool.
4855 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
4856 possible or faking one with a typedef. Changed all callers.
4858 2003-08-15 Gary V. Vaughan <gary@gnu.org>
4860 Still cleaning up the users' module API, by taking out the stuff
4861 that isn't used by any existing modules, and moving specialised
4862 functions out of libm4 and into the module they are used by.
4864 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
4865 * m4/utility.c (m4_skip_space): ...to here the home of its only
4866 use, made static and renamed to `skip_space'. Changed all
4867 callers.
4868 * m4/m4module.h (m4_expand_ranges): Removed prototype.
4869 * m4/utility.c (m4_expand_ranges): Moved definition from here...
4870 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
4871 ltdl.
4872 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
4873 casting .
4874 * modules/gnu.c (builtin_syntax): Import and use in this
4875 builtin implementation.
4876 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
4877 Not used. Deleted.
4878 * m4/macro.c (trace_flush): Except here where the macro is now
4879 manually inlined.
4880 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
4881 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
4882 moved...
4883 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
4884 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
4886 2003-08-14 Gary V. Vaughan <gary@gnu.org>
4888 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
4889 compiler based AC_CHECK_HEADER that was introduced in
4890 autoconf-2.56.
4891 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
4892 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
4893 * configure.ac: Use renamed M4_AC_LIB_GMP.
4895 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
4896 macro that requires arguments! This stops the shell's bad
4897 substitution error at configure time.
4899 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
4900 variables to the testsuite shell. Set the value of USE_GMP so
4901 that the gmp test will run!
4902 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
4904 2003-08-11 Gary V. Vaughan <gary@gnu.org>
4906 Libltdl already has an excellent mechanism for accessing C symbols
4907 in modules. Lets use that! Remove all the exporting cruft and
4908 just use lt_dlsym in conjunction with a few conventions to
4909 simplify module writers' jobs. Also removed the table address
4910 caching code and otherwise simplified the module loader quite a
4911 bit. To access exported symbols in other modules, first the
4912 exporting module must name the symbols <modname>_LTX_<symname>,
4913 and the importing module must define a function type called
4914 <symname>_func. The importer then adds
4915 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
4916 that wishes to call out to the exported functions. Care must be
4917 taken that <symname> is non-NULL in the importing module incase
4918 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
4919 definition was in the importers source. Study
4920 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
4921 m4_module_import will attempt to automatically load a module
4922 required for symbol access if it is not loaded already.
4924 * TODO: Removed the items fixed in this delta.
4925 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
4926 module name.
4927 * m4/ltdl.h (lt_dlhandle_find): Declare it.
4928 * m4/module.c (m4_module_unload): Use it.
4929 * src/freeze.c (reload_frozen_state): Ditto.
4930 * m4/m4module.h (m4_export): Deleted. Removed all references.
4931 (M4_MODULE_IMPORT): New user convenience macro for importing
4932 arbitrary symbols from other modules.
4933 * m4/module.c (m4_module_import): New function to service
4934 M4_MODULE_IMPORT macro.
4935 (module_data): Removed. Looking up the tables on demand with
4936 lt_dlsym, rather than caching their addresses here simplifies the
4937 code substantially.
4938 (m4_get_module_builtin_table, m4_get_module_macro_table):
4939 Removed. Changed all callers.
4940 (set_module_macro_table, set_module_builtin_table): Renamed to
4941 install_macro_table and install_builtin_table respectively, and
4942 simplified now that the cache is no more.
4943 * modules/gnu.c (builtin_symbols): Use this new mechanism to
4944 import m4_dump_symbols from the m4 module.
4945 (builtin_esyscmd): Likewise for m4_set_sysval and
4946 m4_sysval_flush.
4947 * modules/m4.c (m4_export_table): Removed. Functions are
4948 addressed with the new mechanism which doesn't need this.
4949 (m4_set_sysval): New exported accessor function to prevent
4950 problems with variable access on inferior architectures.
4951 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
4952 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
4953 that we can have some type safety.
4954 * modules/modtest.c (export_test): C level exported function for
4955 testing the new import mechanism.
4956 * modules/import.c: New file for the import end of the test.
4957 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
4958 * tests/modules.at: New test cases for intermodule symbol
4959 importing.
4961 2003-08-07 Gary V. Vaughan <gary@gnu.org>
4963 * m4/m4module.c (m4_string): Moved from here...
4964 * m4/m4private.c (m4_string): ...to here.
4966 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
4968 2003-07-29 Gary V. Vaughan <gary@gnu.org>
4970 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
4971 already available to module writers through
4972 m4_{get,set}_nesting_limit_opt(), so moved from here...
4973 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
4974 (m4_create): Use it.
4976 2003-07-28 Gary V. Vaughan <gary@gnu.org>
4978 Aside from auditing path.c for m4module.h api obfuscation, this
4979 delta introduces the concept of private struct members in opaque
4980 data types to GNU m4: See the STYLE file for details.
4982 * TODO: Remind ourselves that a rewrite of path.c is needed.
4983 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
4984 Moved from here...
4985 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
4986 here and renamed. These type definitions are for internal api use
4987 only. Changed all callers.
4988 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
4989 Moved from here...
4990 * m4/path.c (search_path_env_init, search_path_add): ...to here
4991 and renamed. These calls were never used outside this file.
4992 Changed all callers.
4993 (dirpath): Moved functionality of this static declaration...
4994 * m4/m4private.h (struct m4): ...to this new internal only
4995 search_path field. Changed all callers.
4996 (m4__get_search_path): Added new internal api accessor.
4997 * m4/path.c (m4_search_path_info_new): Removed. Not used.
4998 (m4_include_init): Removed...
4999 * m4/m4.c (m4_create): ...because the new m4 field is now
5000 initialised here.
5001 (m4_delete): Recycle search_path memory.
5002 * src/main.c (main): Don't call m4_include_init now that it's
5003 gone!
5004 * doc/STYLE: Document convention for private fields in opaque
5005 ADTs.
5007 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5009 Sometimes exporting the address of a symbol from a module isn't
5010 enough for other modules to call that symbol correctly. If
5011 custom data types are used for function parameters, they need to
5012 be known to the caller. This change introduces the concept of
5013 $(prefix)/include/modules/$(modulename).h to declare those
5014 structures. Also we move m4_dump_symbols from libm4 to the m4
5015 module to show this concept in action.
5017 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
5018 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
5019 exporting data structures from modules/m4.c.
5020 * modules/m4.c, modules/gnu.c: Include it.
5021 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
5022 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
5023 prototypes.
5024 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
5025 Moved from here...
5026 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
5027 ...to here, with slight renaming.
5028 (m4_export_table): Prototype and add m4_dump_symbols.
5029 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
5030 definition of m4_dump_symbols.
5031 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
5032 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
5034 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5036 Create an export table in modules/m4.c in readiness for beefing up
5037 the module loader to track module exports and imports.
5039 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
5040 * m4/debug.c (m4_debug_flush_files): Moved...
5041 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
5042 * modules/gnu.c (builtin_esysval): Use it.
5043 * m4/m4module.h (m4_export): New type for declaring module symbols
5044 for export.
5045 * modules/m4.c (m4_export_table): List symbols exported from this
5046 module for use by other modules.
5048 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5050 An experiment: There is loads of code in libm4 which should be in
5051 the m4 module, but is also used by another module. Just because
5052 some linkers won't cope with calls across dynamic runtime loaded
5053 objects I initially left the code in libm4. It will tidy the
5054 module api immensely if this code moves to the right place, I just
5055 need to remember to invent a suitable calling mechanism at some
5056 point. For now, only modules that are statically linked and
5057 preloaded will get this treatment, so the only platforms that will
5058 break are those that require all symbols to be resolved at link
5059 time.
5061 * TODO: Reminder that what I am doing could reduce portability
5062 unless I do something more robust later.
5063 * m4/m4module.h (m4_sysval): No longer exported from libm4.
5064 * m4/utility.c (m4_sysval): No longer declared in libm4.
5065 * modules/Makefile.am: Reformatting.
5066 * modules/m4.c (m4_sysval): Declare it at place of use.
5067 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
5069 2003-07-23 Gary V. Vaughan <gary@gnu.org>
5071 * m4/m4module.h: Reformatting and rearranging lines a bit.
5072 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
5073 all users.
5074 (m4_call_macro, m4_expand_input): Renamed...
5075 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
5076 callers.
5077 (m4_expansion_level, m4_process_macro): Moved...
5078 * m4/macro.c (expansion_level, process_macro): ...to here, and
5079 made static.
5081 * m4/m4module.h (program_name): Not used by modules at all, so
5082 moved...
5083 * src/main.c (program_name): ...to here.
5084 (print_program_name): Renamed...
5085 (print_program_name_CB): ...to conform to the STYLE guide.
5087 2003-07-23 Gary V. Vaughan <gary@gnu.org>
5089 More refactoring of the m4module.h API. Replace #defines with an
5090 enum, and move non-public functions out of the public API.
5092 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
5093 inclusion.
5094 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
5095 * m4/debug.c (m4_debug, trace): Moved...
5096 * m4/m4private.h (struct m4): ...to fields of this struct.
5097 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
5098 for the new fields.
5099 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
5100 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
5101 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
5102 * m4/m4module.h (m4_context_field_table): Add entries for new
5103 debug_file and trace_messages fields.
5104 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
5105 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
5106 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
5107 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
5108 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
5109 (m4_is_debug_bit): New macro to simplfy checks against the debug
5110 bits above.
5111 (m4_trace_format, m4_trace_header, m4_trace_flush)
5112 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
5113 prototypes.
5114 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
5115 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
5116 * m4/macro.c (trace_format, trace_header, trace_flush)
5117 (trace_prepre, trace_pre, trace_post): ...to these newly static
5118 functions, since they are only ever used from this file. Changed
5119 all callers.
5121 2003-07-17 Gary V. Vaughan <gary@gnu.org>
5123 Change the macros for checking syntax so that matching against
5124 multiple possible syntax classes can be done with a single
5125 comparison some of the time. The various classes are now bits of
5126 an int that can be checked with bitwise logic operators.
5128 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
5129 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
5130 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
5131 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
5132 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
5133 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
5134 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
5135 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
5136 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
5137 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
5138 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
5139 Replace all calls with invocations of these...
5140 (m4_is_syntax, m4_has_syntax): ...New macros.
5141 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
5142 is no longer required with new macros. Changed all callers.
5144 2003-07-15 Gary V. Vaughan <gary@gnu.org>
5146 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
5147 values are returned as part of the internal interface, so they
5148 need to be moved...
5149 * m4/private.h: ...to here.
5150 * m4/macro.c (expand_token): Check for out of range
5151 m4_peek_input() results before looking up in the syntax table.
5152 (collect_arguments): Ditto.
5154 * NEWS: Note `$' syntax class.
5156 2003-07-08 Paul Eggert <eggert@twinsun.com> and
5157 Gary V. Vaughan <gary@gnu.org>
5159 Conform to POSIX if the POSIXLY_CORRECT environment is set.
5160 --traditional `define' now smashes all the definitions.
5162 * NEWS: Explain this.
5163 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
5164 (Extensions): Explain that extensions that are incompatible with
5165 POSIX are disabled if POSIXLY_CORRECT is set.
5166 (Incompatibilities): Remove.
5167 (Define, Other Incompat): Explain difference
5168 between GNU and POSIX behavior of define, pushdef, popdef.
5169 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
5170 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
5171 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
5172 (m4_get_posixly_correct_opt): New macro.
5173 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
5174 POSIXLY_CORRECT.
5175 * modules/m4.c (builtin_functions): defn now takes any number of args.
5176 (builtin_define): Smash all the definitions if
5177 POSIXLY_CORRECT.
5178 (builtin_defn)): Allow any number of arguments.
5179 (builtin_undivert): Do not allow nonnumeric arguments
5180 if POSIXLY_CORRECT.
5181 * src/main.c (main): Set posixly-correct behavior if either
5182 POSIXLY_CORRECT is set, or if -G is given.
5183 * tests/builtins.at: New test for smashed definitions.
5185 2003-06-27 Gary V. Vaughan <gary@gnu.org>
5187 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
5188 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
5189 not to slow the parser down.
5190 (M4__IS_STRING): New macro to test string syntax class membership.
5191 * m4/syntax.c: Adjust docucomment.
5192 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
5193 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
5194 * m4/input.c (init_builtin_token): Comment typo.
5195 (m4__next_token): Comment typo.
5196 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
5197 by using the new M4__IS_STRING macro.
5198 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
5199 variable references in macro expansions.
5201 * doc/m4.texinfo (Eregexp and Regexp): Typo.
5202 (Epatsubst and Patsubst): Typo.
5203 (Eval): Typo.
5205 2003-06-26 Gary V. Vaughan <gary@gnu.org>
5207 Move the global variables that pertain to syntax to a new `struct
5208 m4_syntax_table', and then add one of these to `struct m4'. The
5209 ripple effect through the code to both change formerly global
5210 references, and make sure a suitable context is available in
5211 lexical scope is disproportionately large compared to the size of
5212 the change proper. This change is a large part of decoupling
5213 syntax.c from the rest of the code that uses it.
5215 * m4/m4private.h (struct m4): Add a syntax field.
5216 * m4/m4.c (m4_create): Initialise it,
5217 (m4_delete): Recycle it.
5218 (m4_get_symtab): Remove hand coded version...
5219 (m4_get_symbol_table): ...and generate this with cpp. Changed all
5220 callers.
5221 * m4/m4module.h (m4_context_field_table): Add an extra field so we
5222 can generate m4_get_symbol_table. Add a new row for
5223 m4_get_syntax_table.
5224 (M4SYNTAX): Syntactic sugar for module writers.
5225 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
5226 (m4_syntax_table): New home for syntax related formerly global
5227 variables.
5228 * m4/m4private.h (struct m4_syntax_table): Define it.
5229 * m4/input.c (m4_input_init): Initialisation of these formerly
5230 global variables moved...
5231 * m4/syntax.c (m4_syntax_create): ...to here.
5232 * m4/input.c (m4_input_exit): And similarly, recycling of the
5233 memory used by those values moved...
5234 * m4/syntax.c (m4_syntax_delete): ...to here.
5235 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
5236 Moved to m4/m4private.h.
5237 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5238 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5239 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5240 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
5241 objects. Changed all callers that used to directly access the
5242 global equivalents.
5243 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
5244 Removed and incorporated into m4_syntax_table structure.
5245 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
5246 * m4/syntax.c (m4_set_syntax): Now returns an error status,
5247 instead of requiring a `struct m4' to generate its own errors.
5248 Changed all callers.
5249 * src/main.c (main): Now that the syntax table is initialised as
5250 part of m4_create, we have to manually wipe the syntax entries if
5251 we are about to read a frozen file.
5253 2003-06-26 Gary V. Vaughan <gary@gnu.org>
5255 * doc/STYLE: Added notes on callback naming schemes.
5257 * m4/module.c (m4_set_module_macro_table)
5258 (m4_set_module_builtin_table): Declarations weren't changed when
5259 definitions were renamed on 2003-06-19.
5261 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
5262 neither used nor particularly appropriate since it exposes the
5263 internal workings of the hash module. I haven't yet decided
5264 whether to remove it entirely.
5266 2003-06-20 Gary V. Vaughan <gary@gnu.org>
5268 Two related changes, and a huge knockon effect throughout the
5269 source: Moved the option variables out of global space and into
5270 `struct m4'; made `m4_symtab' a real datatype, so that its api
5271 is not marred passing `struct m4' around just so it can decide
5272 whether to keep traced symbol names or not. Added setters and
5273 getters for the formerly global option variables, and obviously
5274 changed a vast number of functions to take a `struct m4' and use
5275 the getter funcs to find option values.
5277 * m4/utility.c (interactive, sync_output, debug_level)
5278 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
5279 (max_debug_argument_length, warning_status, nesting_limit)
5280 (discard_comments): Removed.
5281 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
5282 (debug_level, max_debug_argument_length, prefix_all_builtins)
5283 (suppress_warnings, discard_comments, interactive, sync_output):
5284 Removed from here...
5285 * m4/m4private.h (struct m4): ...and equivalent fields added to
5286 this structure.
5287 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
5288 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
5289 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
5290 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
5291 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
5292 macros for the new fields.
5293 * m4/m4module.h (m4_context_field_table)
5294 (m4_context_opt_bit_table): Helper macros used to generate
5295 prototypes, setters and getters for new option fields
5296 consistently.
5297 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
5298 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
5299 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
5300 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
5301 (m4_get_interactive_opt, m4_get_sync_output_opt)
5302 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5303 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5304 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
5305 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
5306 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
5307 setter and getter functions generated by cpp from
5308 m4_context_field_table and m4_context_opt_bit_table, exported as
5309 part of the module api. Changed all callers.
5310 * m4/symtab (struct m4_symtab): Used as the concrete type for
5311 m4_symtab now.
5312 (m4_symtab_create): Allocate and initialise a new struct.
5313 (m4_symtab_apply): New function that works like m4_hash_apply, but
5314 with different callbacks specific to symbol tables. Changed all
5315 callers.
5316 (symbol_destroy, arg_destroy, arg_copy): Renamed
5317 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
5318 they have unused parameters for a reason!
5319 (dump_symbol_CB): New callback to dump the contents of a single
5320 symbol.
5321 (symtob_dump): Rewritten in terms of dump_symbol_CB.
5322 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
5323 Changed all callers.
5324 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
5325 of the contained `m4_symtab' at the `no_gnu_extensions' field.
5326 Although I'm not convinced these semantics are correct, they are
5327 at least consistent with how things were before this delta. Also
5328 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
5330 2003-06-19 Gary V. Vaughan <gary@gnu.org>
5332 Tie down the interface to libm4 some more. Make more structures
5333 opaque to modules by moving them to m4private.h, and writing
5334 setters and getters. To win back the speed penalty for doing this
5335 also wrote macroized versions that do know about structure layout
5336 in m4private.h and #include that file into modules when NDEBUG is
5337 defined at compile time. There are still some accessor macros in
5338 m4private.h that need to go, but that is not necessary to clean
5339 the module api up.
5341 * m4/m4module.h (m4_symbol_type): Moved...
5342 * m4/m4private.h (m4__symbol_type): ...to here.
5343 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
5344 (m4_set_symbol_traced, m4_set_symbol_name_traced)
5345 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
5346 (m4_get_symbol_func, m4_symbol_value_create)
5347 (m4_symbol_value_delete, m4_set_symbol_value_text)
5348 (m4_set_symbol_value_func): New exported api to symbols.
5349 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
5350 and m4_is_symbol_value_func.
5351 * m4/m4module.h: Prototype these guys.
5352 * m4/module.c (m4_set_module_macro_table)
5353 (m4_set_module_builtin_table): Make these static, there is no
5354 reason to pollute the api with them.
5355 * m4/m4private.h: Reformatting.
5356 (m4_get_symtab): Only define when NDEBUG is defined.
5357 (m4_get_symbol_value, m4_get_symbol_traced)
5358 (m4_set_symbol_traced, m4_set_symbol_name_traced)
5359 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
5360 (m4_get_symbol_func, m4_symbol_value_create)
5361 (m4_symbol_value_delete, m4_set_symbol_value_text)
5362 (m4_set_symbol_value_func): Macro implementations of the new
5363 functions when NDEBUG is defined.
5364 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
5365 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
5366 Superceded by the above. All callers changed.
5367 (M4ARG): Removed. This is no longer different to the
5368 m4/m4module.h definition.
5369 * modules/gnu.c, modules/m4.c: Only include m4private.h when
5370 NDEBUG is defined. That way we exercise the same (albeit slower)
5371 api that external modules must use.
5373 2003-06-18 Gary V. Vaughan <gary@gnu.org>
5375 Renamed some of the types and their accessors to make more sense.
5376 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
5377 has a stack of SYMBOL_VALUEs.
5379 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
5380 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
5381 m4_get_symbol_value_type, m4_get_symbol_value_text,
5382 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
5383 Changed all callers.
5384 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
5385 (m4_get_token_type): Renamed
5386 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
5387 to the internal api.
5388 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
5389 s/TOKEN_/VALUE_/
5390 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
5391 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
5392 (m4__token_type): Moved here from m4module.h.
5393 (m4__next_token): Renamed from m4_next_token.
5394 * m4/symtab.c: Removed some of the parameterised macro support
5395 functions for modularisation later.
5396 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
5397 m4_hash_dup to perform a true deep copy of the SRC.
5398 (arg_copy): Callback for m4_symbol_value_copy.
5399 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
5400 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
5401 m4_get_symbol_value_func. Changed all callers.
5403 2003-06-18 Gary V. Vaughan <gary@gnu.org>
5405 Tidy up style of hash.[ch] in accordance with doc/STYLE.
5407 * m4/hash.c: Internal symbol renaming and formatting.
5408 (m4_hash_dup): New function to facilitate deep copies of hash
5409 tables.
5410 (m4_hash_apply_func): Returns a void* now, which is a richer type
5411 for returning exceptions (NULL means keep going).
5412 (m4_hash_apply): Ditto.
5413 * m4/hash.h: Declare exported symbols with an explicit extern.
5414 Reformated.
5416 2003-06-17 Gary V. Vaughan <gary@gnu.org>
5418 Still refactoring furiously. This delta represents a change in
5419 semantics to symtab.c. Instead of building temporary m4_tokens
5420 in the caller, and copying fields in the methods, we now create
5421 the actual m4_token for hashing in the caller so the methods just
5422 slot them in directly. Also, this means that we don't lookup a
5423 symbol and get back an allocated but VOID token to copy fields
5424 into, we create the token we want to push and pass that to
5425 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
5426 a few other small changes to stop knowledge of the implementation
5427 of symtab.c leaking out into other files.
5429 * m4/macro.c (expand_argument): Comment typo corrected.
5430 * m4/symtab.c (symtab_fetch): New function to fetch the address of
5431 an interned symbol.
5432 (m4_symbol_pushdef): Take an extra value parameter and use this
5433 directly as the new top of the value stack. All callers changed
5434 to build a token and pass responsibility for memory in, rather
5435 than copying as we used to.
5436 (m4_symbol_define): Also use the new value parameter directly as a
5437 replacement for the top of the value stack. All callers changed
5438 to build a token as above.
5439 (m4_set_symbol_traced): New function to set the traced bit on the
5440 named symbol, creating it if necessary.
5441 (symbol_popval): The guts of the old m4_symbol_popdef.
5442 (m4_symbol_popdef): Use it.
5443 * m4/builtin.c (m4_symbol_set_token): Removed,
5444 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
5445 replaced...
5446 * m4/module.c (m4_set_module_builtin_table)
5447 (m4_set_module_macro_table): ...with these more orthogonal
5448 functions.
5449 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
5450 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
5451 required.
5452 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
5453 (m4_arg_signature_parse): Moved...
5454 * m4/symtab.c: ...to here.
5455 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
5456 screw something up. Moved...
5457 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
5458 actually does a proper deep copy of source to dest.
5460 2003-06-16 Gary V. Vaughan <gary@gnu.org>
5462 Further refactoring to stabilise the module API. Renaming some
5463 functions for orthogonality, and judicious definition migration to
5464 move things out of the set of exported symbols.
5466 * doc/STYLE: New file. Notes on coding style.
5467 * m4/m4module.c: Updated bitrotted docucomment at the top of the
5468 file.
5469 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
5470 m4_get_module_name, m4_get_module_builtin_table,
5471 m4_get_module_macro_table which are verb phrases. Changed all
5472 callers.
5473 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
5474 Moved to...
5475 * m4/module.c (m4_set_module_builtin_table)
5476 (m4_set_module_macro_table): ...here, and renamed. Changed all
5477 callers.
5478 * m4/m4module.c (m4_module_data): This...
5479 * m4/m4private.c (struct m4_module_data): ...and this...
5480 * m4/module.c (module_data) ...consolidated here and no longer
5481 exported. Changed all callers.
5483 2003-06-16 Gary V. Vaughan <gary@gnu.org>
5485 Begin work on lifting the curse of the global variables. To start
5486 with create a `struct m4' context container, and replace
5487 `m4__symtab' with `context->symtab' throughout. This means
5488 initialising a context container in main, and adjusting many
5489 functions between main and the module entry points so that the
5490 container gets passed through. It would have been nice to
5491 defer this until after 1.5, but it has a major effect on the
5492 user's module writing ABI, so it needs to be addressed now - at
5493 least in the areas that impact the ABI. An interrelated change
5494 in the symtab API removes the dependency on a global symbol table,
5495 and instead focuses on a passed table (from the context
5496 container).
5498 * TODO: Reminders for finishing context functionality.
5499 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
5500 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
5501 global variables and eventually allow m4 to be reentrant.
5502 * m4/m4private.h (m4): Define the new structure here...
5503 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
5504 don't carry the overhead of a function call.
5505 * m4/m4module.h: Prototype extern functions from m4/m4.c.
5506 (m4): Declare type for new struct m4 objects.
5507 (M4SYMTAB): User macro to ease finding the symbol table for the
5508 current context for module developers.
5509 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
5510 verb.
5511 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
5512 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
5513 (m4_call_macro, m4_dump_symbols, m4_expand_input)
5514 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
5515 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
5516 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
5517 m4* context parameter. Changed definitions and all callers.
5518 (m4_symtab): Alias for m4_hash to decouple the
5519 m4_symtab api from m4_hash.
5520 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
5521 m4_hash.
5522 (m4_symtab_create): New function to return an initialised
5523 m4_symtab.
5524 (m4_symtab_delete): New function to delete an m4_symtab's memory.
5525 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
5526 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
5527 instead of simply using the global m4__symtab. Changed
5528 definitions and all callers.
5529 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
5530 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
5531 * src/main.c (main): Create a context and use that instead of the
5532 former global m4__symtab.
5534 2003-06-13 Gary V. Vaughan <gary@gnu.org>
5536 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
5537 to the callback. Callbacks should not need to hardcode the
5538 hashtable they are working from, nor should we have to waste the
5539 userdata parameter to pass the table in.
5540 * m4/hash.h (m4_hash_apply_func): Require the initial table
5541 parameter.
5542 * m4/symtab.c (symtab_destroy): Use the passed table instead
5543 of hardcoding m4__symtab.
5544 (m4_symbol_popdef): Don't use the userdata parameter to pass the
5545 table to arg_destroy.
5546 (arg_destroy): Use the hash parameter, ignore userdata.
5547 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
5548 prototype.
5549 (traceon, traceoff): Call set_trace with the extra initial
5550 parameter.
5552 2003-06-13 Gary V. Vaughan <gary@gnu.org>
5554 More refactoring to stabilise the module api, this time for
5555 symtab.c. Additionally, start to pay attention to function names
5556 that don't contain a verb like they should.
5558 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
5559 wrapper for m4_hash_apply to decouple the symtab module from the
5560 hash module.
5561 (m4_symbol_builtin, m4_symbol_macro): Renamed to
5562 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
5563 callers.
5564 (m4_symbol_delete): Create a macro version to save a function
5565 call.
5566 (m4_token_t, m4_data_t): These violate the POSIX reserved
5567 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
5568 all callers.
5569 (m4_token_type): Renamed to m4_token_get_type.
5570 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
5571 (m4_symtab_exit): Removed from the exported module
5572 api...
5573 * m4/m4private.h (m4__symtab, m4__symtab_init)
5574 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
5575 renamed and added to the internal api. Changed all callers.
5576 (m4_symtab_apply): A faster macro version of the function for
5577 users of the internal api.
5578 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
5579 symbol_destroy and arg_destroy.
5580 (symtab_debug): Added a prototype.
5581 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
5582 so that callers in this file get the faster macro versions from
5583 m4/m4private.h.
5585 2003-06-12 Gary V. Vaughan <gary@gnu.org>
5587 Refactoring modules to rationalise the API into an external
5588 documented (eventually!) API for use by modules in the `m4_'
5589 namespace declared in m4/m4module.h, an internal API between the
5590 source files we ship (including our shipped modules) in the `m4__'
5591 namespace declared in m4/m4private.h and making the rest as
5592 cohesive as possible with liberal use of the `static' keyword.
5593 This change represents an audit to m4/module.c along these
5594 guidelines.
5596 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
5597 Removed. No longer used.
5598 (m4_module_close): Removed prototypes.
5599 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
5600 from the exported module api...
5601 * m4/m4private.h (m4__module_init, m4__module_open)
5602 (m4__module_exit): ...and renamed and added to the internal api.
5603 Changed all callers.
5604 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
5605 Centralised definitions after renaming...
5606 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
5607 (M4_FINISH_SYMBOL): ...and removing from here.
5608 (m4_module_dlerror, m4_module_remove, m4_module_close)
5609 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
5610 module_remove, module_close and caller_id.
5611 (MODULE_SELF_NAME): New macro to make reporting self errors
5612 easier.
5613 (m4_module_load, module_close, module_remove): Use it.
5614 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
5615 name.
5616 * src/main.c (main): Use it.
5618 2003-06-12 Gary V. Vaughan <gary@gnu.org>
5620 * README: Remove references to --enable-changeword, which has been
5621 removed from the code.
5623 2003-06-11 Gary V. Vaughan <gary@gnu.org>
5625 Getting rid of the annoying bug with configure --enable-debug,
5626 which spewed -e: command not found errors. This was an interaction
5627 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
5628 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
5629 branch-1-5) to get the full fix.
5631 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
5632 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
5633 and then use the probed value of $SED.
5634 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
5635 this, it messes up the AC_REQUIRE stack.
5637 2003-06-10 Gary V. Vaughan <gary@gnu.org>
5639 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
5640 the destroy callback.
5641 (m4_arg_destroy): Use the hash address to free the hash node key
5642 field.
5644 2003-06-06 Gary V. Vaughan <gary@gnu.org>
5646 First cut at formal parameters in macros.
5648 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
5649 * m4/xstrzdup.c: New file.
5650 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
5651 associative array of parameter names to details.
5652 (m4_symbol_token): Capture macro names with parameter lists.
5653 (m4_arg_signature_parse): And build an associative array to hang
5654 from the symbol structure to map names to details.
5655 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
5656 m4_hash_resize idiom. Now that we potentially add a little hash
5657 table to many of the entries in the symbol table, added an extra
5658 arg to set the initial size. Changed all callers.
5659 (m4_hash_apply): New function that is basically a generalised
5660 version of...
5661 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
5662 all callers to call m4_hash_apply instead.
5663 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
5664 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
5665 m4_arg_signature association that might be attached to the symbol,
5666 * m4/hash.h (m4_hash_apply_func): Replacement type for...
5667 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
5668 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
5669 parameter lists.
5670 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
5671 (M4_IS_IDENT): Detect characters that can be safely used in
5672 parameter names.
5673 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
5674 * m4/macro.c: Corrected grammar in some comments. Use `token'
5675 rather than `td' for m4_token variables.
5676 (m4_process_macro): If we find a dollar followed by some
5677 M4_IS_IDENT characters, replace that with the contents of the argv
5678 entry with offset stored in the m4_token_arg associated with the
5679 collected identifier.
5681 2003-06-05 Gary V. Vaughan <gary@gnu.org>
5683 Begin preparations for supporting formal parameters in m4 macros.
5685 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
5686 the details of a formal parameter.
5687 (m4_token): Add an arg_signature member to hold a hash table for
5688 looking up formal parameters.
5689 * m4/input.c: Update more bitrotted comments.
5690 (m4_push_builtin): Initialise arg_signature member.
5691 (init_builtin_token): Copy arg_signature member.
5692 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
5693 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
5694 replace...
5695 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
5696 (m4_macro_pushdef, m4_macro_define): ...these, And...
5697 (m4_symbol_token): ...wrapped around this new function, which
5698 vastly simplifies the arguments required by the functions it
5699 replaces.
5700 Changed all callers.
5702 2003-06-05 Gary V. Vaughan <gary@gnu.org>
5704 * m4/macro.c: Format changes.
5706 2003-06-04 Gary V. Vaughan <gary@gnu.org>
5708 * m4/input.c: Updated various bitrotted comments.
5709 (m4_push_builtin): Just pass the whole m4_token, rather than
5710 extracting all the fields in the caller. This also allows us to
5711 check the token type for consistency.
5712 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
5713 Renamed to builtin_funcs, builtin_peek, builtin_read,
5714 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
5715 the code. Changed all callers.
5716 (struct input_block): Similarly renamed u_m member to u_b, and
5717 changed all callers.
5718 (m4_next_token): Use bzero to initialise the data fields.
5719 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
5721 2003-05-29 Gary V. Vaughan <gary@gnu.org>
5723 These changes were necessary to get m4 to build on my iBook
5724 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
5725 (GCC) 3.1 20020420 (prerelease)":
5727 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
5728 inclusion of module loader headers.
5729 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
5730 * m4/Makefile.am: Ditto.
5731 (libm4_la_LIBADD): Added $(LTLIBINTL).
5732 * m4/utility.c (program_name): Removed declaration in favour of
5733 the one already in error.c!
5734 * m4/m4module.h (program_name): Define to program_invocation_name
5735 when using GNU C library. Use an explicit extern declaration.
5736 (interactive, sync_output, debug_level, hash_table_size)
5737 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
5738 (suppress_warnings, warning_status, nesting_limit, discard_comments)
5739 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)

5741 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
5742 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)

5746 (m4_current_line, m4_current_diversion, m4_output_current_line):
5747 Don't rely on default, use an explicit extern.
5748 * m4/error.h (error, error_at_line, error_print_progname)
5749 (error_message_count, error_one_per_line): Ditto.
5750 * m4/ltdl.c: Update from CVS libtool.
5751 * m4/ltdl.h: Ditto.
5752 * commit: Update from CVS cvs-utils.
5754 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
5756 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
5757 * po/boldquot.sed: New file, from gettext-0.11.5.
5758 * po/en@boldquot.header: New file, from gettext-0.11.5.
5759 * po/en@quot.header: New file, from gettext-0.11.5.

5762 * po/remove-potcdate.sin: New file, from gettext-0.11.5.
5763 * po/Rules-quot: New file, from gettext-0.11.5.
5765 2002-11-04 Akim Demaille <akim@epita.fr>
5767 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
5768 running m4 itself.
5769 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
5771 2002-11-04 Akim Demaille <akim@epita.fr>
5773 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
5775 2002-11-04 Akim Demaille <akim@epita.fr>
5777 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
5778 used as `external', and Libtool 1.4.3.
5779 (LINGUAS): Remove.
5780 (LTLIBOBJS): Don't play with it.
5781 * intl/: Remove.
5782 * Makefile.am (SUBDIRS): Remove intl.
5783 (ACLOCAL_AMFLAGS): Add -I config.
5784 (EXTRA_DIST): Add config/config.rpath.
5785 * po/LINGUAS: New.
5786 * po/Makevars: New.
5787 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
5789 2002-05-29 Gary V. Vaughan <gary@gnu.org>
5791 Preparations for refactoring syntax tables to allow reverse
5792 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
5793 speed of normal lookups in an array of unsigned short.
5795 * m4/input.c (single_quotes, single_comments, use_macro_escape):
5796 Moved from here...
5797 * m4/m4private.h (m4__single_quotes, m4__single_comments,
5798 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
5799 is for internal symbols which unavoidably pollute the global
5800 namespace, but are not published APIs.
5801 Adjusted all callers.
5802 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
5803 m4_set_comment, m4_set_syntax, set_syntax_internal,
5804 unset_syntax_attribute): Moved from this file...
5805 * m4/syntax.c: New. ...to this file.
5806 Also added an m4_syntax_exit stub for orthogonality.
5807 * src/main.c (main): Use it.
5808 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
5809 * m4/m4module.h: Reformatting. New prototypes.
5811 2002-05-29 Gary V. Vaughan <gary@gnu.org>
5813 * bootstrap (aclocal_apiversion): The aclocal apiversion is
5814 distinct from the automake release number (in that the apiversion
5815 apparently has no micro-version-component).
5816 (aclocal_apilibdir): Use it.
5818 2002-05-28 Gary V. Vaughan <gary@gnu.org>
5820 * m4/hash.c (m4_hash_resize): New function.
5821 * m4/hash.h: Add prototype.
5822 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
5823 benchmarking to find a good value for, say, autoconf. This is
5824 already a little quicker than before for me.
5826 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
5827 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
5828 and reenamed.
5829 * m4/hash.h: Adjust prototypes.
5831 2002-01-22 Akim Demaille <akim@epita.fr>
5833 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
5834 APIVERSION scheme.
5835 * tests/Makefile.am (package.m4): New.
5836 * tests/atlocal.in: Adjust to CVS Autotest.
5837 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
5838 * configure.ac: LIBOBJ is a forbidden string.
5839 Simplify AM_INIT_AUTOMAKE invocation.
5840 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
5841 options.m4.
5843 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
5845 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
5847 2001-10-19 Akim Demaille <akim@epita.fr>
5849 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
5851 2001-10-19 Akim Demaille <akim@epita.fr>
5853 * m4/input.c (m4_next_token): Display where was opened what is
5854 not closed.
5856 2001-10-19 Akim Demaille <akim@epita.fr>
5858 * m4/macro.c (expand_argument): Display where was opened what is
5859 not closed.
5861 2001-10-18 Akim Demaille <akim@epita.fr>
5863 * m4/input.c, modules/m4.c: Formatting changes.
5865 2001-10-17 Gary V. Vaughan <gary@gnu.org>
5867 * bootstrap: s/configure.in/configure.ac/
5869 2001-10-16 Gary V. Vaughan <gary@gnu.org>
5871 * m4/symtab.c (m4_symbol_destroy): This function calls
5872 m4_symbol_popdef, which recycles a symbols memory when the last
5873 definition is popped. Since we were passing the address of the
5874 symbol name found in the symbol table, and it was being removed
5875 partway through m4_symbol_destroy() we were referencing freed
5876 memory for the balance of the function. Now we take a copy of the
5877 symbol name tring and use that as a key into the symbol
5878 table... that way if the original symbol name is freed, the copy
5879 is still valid.
5881 2001-10-13 Akim Demaille <akim@epita.fr>
5883 * m4/ltdl.c: Update.
5885 2001-10-13 Akim Demaille <akim@epita.fr>
5887 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
5888 Don't gettextize internal error messages.
5890 2001-10-13 Akim Demaille <akim@epita.fr>
5892 * tests/macros.at (Arity and defn): New failing test.
5893 (Arity, defn, and freeze): New.
5895 Fix `Arity and defn'.
5897 * m4/input.c (m4_push_macro): Don't forget the arity.
5898 * modules/m4.c (defn): Likewise.
5900 2001-10-13 Akim Demaille <akim@epita.fr>
5902 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
5903 to...
5904 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
5905 (Propagation of traceon, Propagation of --trace): this new file.
5907 2001-10-13 Akim Demaille <akim@epita.fr>
5909 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
5910 interface instead of (name, argc...).
5911 Upon failure, specify which argument was guilty.
5912 Adjust callers.
5914 2001-10-13 Akim Demaille <akim@epita.fr>
5916 * modules/evalparse.c: Save translators' time: don't translate
5917 internal error messages.
5918 (m4_evaluate): Simplify/normalize error messages.
5919 * doc/m4.texinfo (Eval): Adjust.
5921 2001-10-13 Akim Demaille <akim@epita.fr>
5923 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
5924 where no checking is needed.
5925 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
5926 interface instead of (name, argc...).
5927 Adjust callers.
5928 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
5929 elsewhere.
5931 2001-10-13 Akim Demaille <akim@epita.fr>
5933 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
5934 exclude the builtin name from the count.
5935 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
5936 calling ifelse with a single argument is valid.
5937 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
5938 with 1 and 2 args, mostly to strengthen the test suite.
5940 2001-10-13 Akim Demaille <akim@epita.fr>
5942 * m4/output.c (m4_make_diversion, m4_insert_file)
5943 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
5945 2001-10-12 Gary V. Vaughan <gary@gnu.org>
5947 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
5948 since we call these things builtins in the rest of the code!
5950 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
5952 2001-10-12 Gary V. Vaughan <gary@gnu.org>
5954 Rather than forcing each builtin definition to manage its own
5955 argument range checking, tabulate the maxima and minima for all
5956 builtins in each module. This forces us to consider what the
5957 valid ranges for each builtin should be, and moves the checking
5958 code out of each builtin implementation and into the builtin
5959 caller infrastructure.
5961 * m4/m4module.h (struct m4_builtin): Add argument minima and
5962 maxima.
5963 * m4/m4private.h (struct m4_token): Reflect them here too.
5964 * m4/input.c (struct input_block): ...and here.
5965 (m4_token_copy): New function for token copying.
5966 (init_macro_token): Copy them from a token to the input stack.
5967 (m4_next_token): Don't forget to initialise them for text
5968 macros.
5969 * m4/macro.c (expand_argument): Use m4_token_copy, and also
5970 check argument counts before calling the builtin handler.
5971 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
5972 (m4_symbol_macro): Likewise.
5973 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
5974 parameters. Updated all callers.
5975 (m4_builtin_define): Ditto.
5976 (m4_macro_pushdef, m4_macro_define): Ditto.
5977 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
5978 * modules/evalparse.c: Declare argument counts for defined
5979 builtins and remove explicit calls to m4_bad_argc().
5980 * modules/gnu.c: Ditto.
5981 * modules/load.c: Ditto.
5982 * modules/m4.c: Ditto.
5983 * modules/modtest.c: Ditto.
5984 * modules/mpeval.c: Ditto.
5985 * modules/perl.c: Ditto.
5986 * modules/shadow.c: Ditto.
5987 * modules/stdlib.c: Ditto.
5988 * modules/time.c: Ditto.
5989 * TODO: Updated.
5991 2001-10-10 Gary V. Vaughan <gary@gnu.org>
5993 The trace semantics now attach the trace bit to a symbol name.
5994 For as long as a traceon(`foo') is active, calls to foo will be
5995 traced regardless of intervening undefines or module unloads.
5996 Fixed the flag propogation issues differently to the fixes
5997 reverted with the last attempt at nailing down trace:
5999 * m4/m4private.h: This file is not visible outside of the m4
6000 source tree, so I removed all the `M4_' and `m4_' prefixes to save
6001 on typing. Updated all clients.
6002 (m4_token): New typedef contains the fields that need to be passed
6003 around with the low level tokeniser.
6004 (m4_token_data): Removed.
6005 (m4_symbol): Now contains the traced flag again.
6006 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
6007 the trace bit set. This change is contained entirely within this
6008 module and doesn't leak out into the callers. Updated all
6009 clients.
6010 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
6011 new fields in m4_token. Updated all clients.
6012 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
6013 that `groks_macro_args' and `blind_if_no_args' flags are retained
6014 when defn() results are passed around in m4 code. Updated all
6015 callers.
6016 (m4_builtin_define): Ditto.
6017 (m4_macro_pushdef, m4_macro_define): Ditto.
6018 * m4/input.c (struct input_block): Add a flags field to facilitate
6019 the above.
6020 (m4_push_macro): ...use it.
6021 (init_macro_token): Retrieve it.
6022 (m4_next_token): Initialise it.
6023 * m4/macro.c (expand_argument): Copy it.
6024 * m4/m4module.h: Adjust.
6025 * tests/builtins.at: Adjust the expected output of the trace
6026 tests to reflect the change in semantics.
6027 * tests/modules.at (modules: trace): Check that unloading a
6028 module which supplies a traced symbol definition doesn't lose te
6029 trace bit.
6031 2001-10-07 Gary V. Vaughan <gary@gnu.org>
6033 * modules/gnu.c (m4_macro_table): Display the timetamp when
6034 expanding __m4_version__.
6036 * configure.ac (--with-modules): Forgot a comma in the
6037 AC_HELP_STRING parameter list.
6039 2001-10-05 Gary V. Vaughan <gary@gnu.org>
6041 * bootstrap: Remove aclocal.m4t when it is no longer required.
6043 2001-10-05 Akim Demaille <akim@epita.fr>
6045 * tests/Makefile.am: Adjust for gnuprog2.
6046 * tests/m4.in: There can be a leading path.
6047 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
6048 * tests/testsuite.at: Adjust to the most recent Autotest.
6049 (AT_CHECK_M4_FILTER): Fix and rename as...
6050 (AT_TEST_M4): this.
6051 * tests/others.at: Use it.
6053 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
6054 variable in shell scripts, one uses `$'...
6056 2001-10-04 Gary V. Vaughan <gary@gnu.org>
6058 * configure.ac: `rm -f $m4_getopt_h' was lost.
6060 2001-10-04 Gary V. Vaughan <gary@gnu.org>
6062 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
6063 time. Define it for config.h in order to...
6064 * src/main.c (main): ...display the timestamp for --version.
6066 2001-10-04 Akim Demaille <akim@epita.fr>
6068 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
6069 previous builtins `regexp' and `patsubst'.
6070 (regexp, patsubst): Use them.
6071 (eregexp, epatsubst): New builtins.
6072 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
6073 (Epatsubst and Patsubst, Eregexp and Regexp): these.
6074 (Extensions): More info on REs.
6076 2001-10-04 Akim Demaille <akim@epita.fr>
6078 * modules/modtest.c (init_handler): Consistently output to stderr.
6079 (finish_handler): New.
6080 (test): The `if' is an `assert'.
6081 * tests/modules.at: Adjust.
6083 2001-10-04 Akim Demaille <akim@epita.fr>
6085 * m4/utility.c (m4_bad_argc): Detail the mismatches.
6087 2001-10-01 Akim Demaille <akim@epita.fr>
6089 * tests/generate.awk: Tag the tests with `documentation'.
6090 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
6091 Use the make the existing modtest tests more uniform, and complete
6092 the set of possibilities.
6094 2001-10-01 Akim Demaille <akim@epita.fr>
6096 * config/gmp.m4: Consult the user before using GMP: use
6097 --without-gmp.
6098 * configure.ac: Adjust.
6099 * modules/gmp.c: No protection needed as the module is not built
6100 if GMP is not used.
6102 2001-10-01 Akim Demaille <akim@epita.fr>
6104 * tests/generate.awk: Remove debugging code.
6105 (fatal): Specify the current location.
6107 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
6108 * modules/gnu.c, modules/m4.c: Use M4ARG.
6110 2001-10-01 Akim Demaille <akim@epita.fr>
6112 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
6113 (m4_regexp_compile): New.
6114 (regexp, patsubst): Use it.
6116 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6118 Reinstate the memory handling improvements from the patch I just
6119 reverted. Relevant ChangeLog entries repeated here:
6121 * m4/module.c (m4_module_remove): New function that holds the core
6122 of the old m4_module_unload.
6123 (m4_module_unload): Use it.
6124 (m4_module_unload_all): When we know the modules will never be
6125 used again (i.e. on exit), free up as much module memory as
6126 possible. There are still some artifacts from resident modules
6127 living inside ltdl.c, but everything else is freed.
6128 * m4/debug.c (m4_debug_exit): Free memory allocated in
6129 m4_debug_init().
6130 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
6131 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
6132 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
6133 * m4/m4module.h: Updated prototypes.
6134 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
6135 * m4/hash.h: Updated prototypes.
6136 * src/main.c (main): Use all these new functions to clean up as
6137 much memory as possible before exit.
6139 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6141 Reverted my large patch for removing the old m4_symbol
6142 structure on 2001-09-20. We are still not happy about the way
6143 trace works in conjunction with defn and undefine, and leaving
6144 the reverted patch active prevents us from moving the traced
6145 bit from the definition back to the symbol.
6147 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6149 * configure.in: Moved to...
6150 * configure.ac: ...here. Added a libtool like timestamped
6151 banner, and tidied up the libltdl cruft.
6152 * config/mkstamp: Script to extract a timestamp from ChangeLog.
6153 * modules/Makefile.am (INCLTDL): Removed. This is required
6154 only when libltdl is configured in a subdirectory.
6155 * src/Makefile.am: Ditto.
6156 (LIBADD_DL): No need to add this again, libtool already knows
6157 that libm4.la depends on it.
6158 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
6159 them.
6161 * TODO: stackovf.c is basically broken.
6162 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
6164 2001-09-28 Akim Demaille <akim@epita.fr>
6166 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
6168 2001-09-27 Akim Demaille <akim@epita.fr>
6170 * tests/m4.in: Don't use short options.
6171 Simplify the stderr signature normalization.
6173 2001-09-27 Akim Demaille <akim@epita.fr>
6175 tests/m4 shall be position independent.
6177 * tests/m4.in: New.
6178 * tests/m4: Remove.
6179 * tests/testsuite.at: No args to AT_INIT.
6180 * configure.in, tests/Makefile.am: Adjust.
6182 2001-09-22 Akim Demaille <akim@epita.fr>
6184 Autotest has changed again.
6186 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
6187 (package.m4): Remove.
6188 * configure.in: Adjust to LIBADD_GMP.
6190 2001-09-21 Gary V. Vaughan <gary@gnu.org>
6192 * config/gmp.m4 (AC_ARG_WITH): Removed.
6193 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
6194 (AC_LIB_GMP): When performing a test compile against libgmp,
6195 include the header gmp.h if possible, and link against -lgmp. If
6196 they both work define USE_GMP.
6197 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
6198 (mpeval_LTX_init_func): Complain on load that there was no libgmp
6199 at compile time.
6201 2001-09-20 Gary V. Vaughan <gary@gnu.org>
6203 * m4/evalparse.c: Moved to...
6204 * modules/evalparse.c: ...here. This code is shared between
6205 modules/mpeval.c and modules/m4.c, so there is no need to pollute
6206 the libm4 API with its details. Moderately rewritten to interface
6207 into its clients more simply.
6208 * m4/eval.c: Deleted. Migrated functionality to...
6209 * modules/m4.c: ...here.
6210 (builtin_eval): Implemented in terms of the new interface style.
6211 * modules/mpeval.c (builtin_mpeval): Ditto.
6212 * m4/m4module.h: Removed references to the former m4/eval.c.
6213 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
6214 (EXTRA_libm4_la_SOURCES): Deleted.
6215 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
6216 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
6218 2001-09-20 Akim Demaille <akim@epita.fr>
6220 * config/gmp.m4 (AM_WITH_GMP): Rename as...
6221 (AC_LIB_GMP): this.
6222 By default, use gmp.
6223 Massive revamping.
6224 * configure.in: Adjust.
6225 Use Automake conditionals for USE_GMP.
6226 Always compute sizeof (long long int).
6227 This was a bug BTW, as `eval' (not `mpeval') depends on it:
6228 before, it was used _only_ if mpeval was not activated.
6229 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
6230 (mpeval_la_LIBADD): New macros.
6231 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
6232 Indent.
6233 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
6234 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
6235 WITH_GMP.
6237 2001-09-20 Akim Demaille <akim@epita.fr>
6239 * tests/Makefile.am (package.m4): New.
6240 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
6242 2001-09-20 Gary V. Vaughan <gary@gnu.org>
6244 More cleanup. After the last patch, m4_symbol holds nothing but
6245 the head of a chain of m4_token_data. So I have removed the old
6246 m4_symbol, so that m4_token_data chains are stored directly in the
6247 value cell of a hash table node. But there's more... m4_symbol
6248 was a more natural name for the symbol value cell, and now that it
6249 is gone I have renamed the former m4_token_data structure to
6250 m4_symbol. This change turned out to be a pig to get right, since
6251 the original code didn't need to modify the value cell itself,
6252 since changing the chain happened inside the m4_symbol that used
6253 to be returned -- I had to pass the address of the value cell
6254 across various function calls, incase the head value changed. I
6255 also tightened up the memory management to help me find a nasty
6256 memory corruption bug that took me all night to track down...
6258 * m4/m4private.h (struct m4_symbol): Removed.
6259 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
6260 all references.
6261 * m4/hash.c (m4_hash_iterator_value): Return the address of the
6262 value cell. Updated all callers.
6263 * m4/symtab.c: Took advantage of the simplification in the data
6264 structures to rewrite a lot of this file more simply. There is
6265 still some room for optimisation here, but we should tackle that
6266 systematically closer to the release.
6268 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
6269 revealed. This version is ahead of CVS libtool until I get chance
6270 to flush my changes.
6271 * m4/module.c (m4_module_remove): New function that holds the core
6272 of the old m4_module_unload.
6273 (m4_module_unload): Use it.
6274 (m4_module_unload_all): When we know the modules will never be
6275 used again (i.e. on exit), free up as much module memory as
6276 possible. There are still some artifacts from resident modules
6277 living inside ltdl.c, but everything else is freed.
6278 * m4/debug.c (m4_debug_exit): Free memory allocated in
6279 m4_debug_init().
6280 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
6281 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
6282 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
6283 * m4/m4module.h: Updated prototypes.
6284 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
6285 * m4/hash.h: Updated prototypes.
6286 * src/main.c (main): Use all these new functions to clean up as
6287 much memory as possible before exit.
6289 2001-09-18 Gary V. Vaughan <gary@gnu.org>
6291 The `traced' flag needs to be attached to the definition of a
6292 symbol rather than the current symbol containing the definition.
6293 Implementing this showed up some long standing post 1.4 bugs in
6294 flag propogation which I also fixed.
6296 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
6297 (struct m4_token_data): And add it back in here.
6298 * m4/input.c (init_macro_token): Propogate the traced flag
6299 correctly.
6300 * m4/macro.c (expand_argument): Ditto.
6301 * tests/builtins.at (trace2, trace3): New tests based on Akim's
6302 sadistic email ;-)
6304 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6306 * m4/m4private.h (struct m4_token_data): Simplified by removing
6307 the redundant `traced' flag, and one level of structure nesting.
6308 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
6309 * m4/input.c (init_macro_token): No need to initialise removed
6310 `traced' field.
6311 * m4/macro.c (expand_argument): No need to copy it either.
6312 * m4/utility.c (m4_token_data_func_traced): Or provide an access
6313 function.
6315 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
6316 dependant on multiple symbols with the same key, so preserving
6317 relative symbol order in each bucket during resizing is no longer
6318 required. The resize function is considerably faster as a result.
6320 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
6321 s/m4_symbol_insert/m4_symbol_define/g;
6322 s/m4_builtin_insert/m4_builtin_define/g;
6323 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
6325 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6327 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
6328 commits, the m4_lookup_symbol dispatch function is split into
6329 specialised functions that must be called directly.
6331 * m4/m4module.h (m4_symbol_lookup_t): Removed.
6332 * m4/symtab.c (m4_lookup_symbol): Removed.
6333 (m4_symbol_builtin, m4_symbol_macro): New functions.
6334 * m4/builtin.c (m4_builtin_define): Split into...
6335 (m4_builtin_pushdef, m4_builtin_insert): ...these.
6336 (m4_macro_define): Split into...
6337 (m4_macro_pushdef, m4_macro_insert): ...these.
6338 * src/main.c (main): Set command line macros from `-D' parameters
6339 using `m4_macro_define'.
6341 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6343 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
6344 this from m4_remove_table_reference_symbols().
6345 * m4/m4module.h, m4/module.c: Updated all references.
6347 2001-09-07 Akim Demaille <akim@epita.fr>
6349 * modules/stdlib.c, modules/times.c: Misc cleanups.
6351 2001-09-07 Akim Demaille <akim@epita.fr>
6353 * configure.in: We now need Autoconf 2.52e.
6354 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
6355 and `M4_SYMBOL_DELETE'.
6356 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
6357 * src/main.c (main): Adjust.
6359 2001-09-06 Gary V. Vaughan <gary@gnu.org>
6361 Fix the obstack.h problem once and for all! At configure time we
6362 can test for a system supplied obstack.h: depending on the
6363 result, we now generate system.h with an #include of the correct
6364 header. As a bonus, I've also added a --with-included-obstack,
6365 incase the user doesn't like the system obstack for some
6366 reason... and also we can test the shipped obstack on a system
6367 that has oe of its own. We also now need to be careful to add
6368 build directories to the include search path, since the generated
6369 system.h will be in the build tree.
6371 * configure.in (AC_CONFIG_FILES): Generate system.h from
6372 system-h.in.
6373 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
6374 include the system obstack header or the copy shipped with M4.
6375 Allow the user to override configure and force the build to use
6376 the shipped version.
6377 * m4/system-h.in: New file, template for...
6378 * m4/system.h: ...this. Now deleted.
6379 * m4/m4module.h: Include system.h before everything else.
6380 * src/freeze.c: Ditto.
6381 * m4/Makefile.am (dist-hook): Remove generated system.h.
6382 (INCLUDES): Check builddir for generated headers before checking
6383 srcdir.
6384 * modules/Makefile.am (INCLUDES): Ditto.
6385 * src/Makefile.am (INCLUDES): Ditto.
6387 2001-09-05 Gary V. Vaughan <gary@gnu.org>
6389 * TODO: Remove the items that have been addressed already.
6391 2001-09-05 Akim Demaille <akim@epita.fr>
6393 * src/main.c (main): Standardize --version.
6395 2001-09-05 Akim Demaille <akim@epita.fr>
6397 * modules/format.c (format): Have a bigger `str'.
6399 2001-09-05 Akim Demaille <akim@epita.fr>
6401 Rationalize warnings, reporting the macro name as if it were a
6402 program name, and assertions.
6404 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
6405 (M4WARN): New.
6406 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
6407 (m4_symbol_delete):
6408 Use assert for internal errors.
6409 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
6410 M4WARN.
6411 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
6412 M4WARN and assert.
6413 * tests/builtins.at (pushpop): Adjust.
6415 2001-09-05 Akim Demaille <akim@epita.fr>
6417 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
6418 with pointers.
6420 2001-09-05 Akim Demaille <akim@epita.fr>
6422 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
6423 * m4/macro.c, m4/symtab.c: Adjust.
6425 2001-09-05 Akim Demaille <akim@epita.fr>
6427 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
6428 (m4_symbol_pop, m4_symbol_del): this.
6429 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
6430 (m4_symbol_popdef, m4_symbol_delete): New.
6431 (m4_lookup_symbol): Adjust.
6432 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
6434 2001-09-05 Akim Demaille <akim@epita.fr>
6436 * m4/m4module.h (m4_symbol_lookup): Rename as...
6437 (m4_symbol_lookup_t): this.
6439 2001-09-05 Akim Demaille <akim@epita.fr>
6441 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
6442 unused.
6443 * m4/symtab.c (m4_lookup_symbol): Adjust.
6445 2001-09-03 Gary V. Vaughan <gary@gnu.org>
6447 Bootstrap will now work with Libtool 1.4.1 or higher:
6448 * bootstrap: Remove stale autom4te.cache files when
6449 rebootstrapping.
6450 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
6451 libtool.m4.
6452 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
6453 libtool.m4 directly.
6454 Run libtoolize to refresh ltmain.sh.
6455 * config/ltmain.sh: Deleted.
6456 * acinclude.m4: Deleted.
6457 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
6459 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
6460 implementation for the cvs impaired libtool user.
6462 2001-09-03 Akim Demaille <akim@epita.fr>
6464 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
6465 internal errors.
6466 Avoid using `default' in switch, as it hides useful compiler
6467 warnings when a case is forgotten.
6469 2001-09-03 Akim Demaille <akim@epita.fr>
6471 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
6472 is no such thing as `WITH_MODULES'.
6474 2001-09-03 Akim Demaille <akim@epita.fr>
6476 Improve the test suite's selfcontainedness.
6478 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
6479 (Include, Undivert): Tag the other input files.
6480 * tests/generate.awk: Catch `@comment file:'.
6481 `-I $src' is no longer needed.
6482 `next' is really like `return': the rest is skipped.
6483 Adjust to `input.m4'.
6484 (fatal): New function.
6485 * tests/foo, tests/incl.m4: Remove.
6487 2001-09-01 Gary V. Vaughan <gary@gnu.org>
6489 The shadowing mechanism and, infact, the whole symbol table
6490 implementation was creaking under the weight of the features piled
6491 on top of it. We now have a separate hash table module which will
6492 dynamically resize to keep symbol density withing good performace
6493 limits, and a new symtab module layered above it. Symbol lookups
6494 are now marginally more efficient (since the shadowed flag is no
6495 longer required) and symbol removal, such as on module unload, is
6496 considerably faster due to a reorganisation of the data structures
6497 used in symtab.c.
6499 * src/main.c (main): Don't mention `-H'.
6500 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
6501 effect.
6502 * NEWS: Updated.
6503 * m4/hash.c: New generalised dynamic hash table data structure
6504 management module.
6505 * m4/hash.h: Public interface.
6506 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
6507 (libm4_la_SOURCES): Add hash.c.
6508 * m4/symtab.c: More or less rewritten from scratch, within the
6509 bounds of the previous API.
6510 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
6511 call. Updated all callers.
6512 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
6513 declarations to reflect API changes.
6514 (M4INIT): Generate a declaration too, to avoid the warning with
6515 --enable-debug builds.
6516 (M4FINISH): Ditto.
6517 (HASHMAX): Removed.
6518 * m4/utility.c (hash_table_size): Removed.
6519 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
6520 names, which are then looked up by builtin_dumpdef() as necessary.
6521 This implies a small speedup in builtin_symbols(), which discarded
6522 all of the symbol info under the old call.
6523 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
6524 shadowing is implicit in respect to the new data structures.
6525 symbol names are no longer duplicated here, they are stored in the
6526 key field of the hash table.
6527 Moved macro_args and blind_no_args...
6528 (m4_token_data): ...to here.
6529 m4/macro.c (expand_macro): Added a name argument since the symbol
6530 name is no longer copied into each struct m4_symbol. Modified all
6531 callers.
6532 (collect_arguments): Ditto.
6533 * modules/m4.c (set_trace): Ditto.
6534 * modules/gnu.c (builtin_symbols): Updated.
6535 * src/freeze.c (produce_symbol_dump): Much improved in light of
6536 the improved symbol table layout.
6538 2001-09-01 Gary V. Vaughan <gary@gnu.org>
6540 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
6541 to M4_SYMBOL_NEXT.
6542 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
6543 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
6544 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
6545 SYMBOL_HANDLE): Ditto.
6546 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
6547 modules/gnu.c, modules/m4.c, src/freeze.c,
6548 src/main.c: Updated all references.
6550 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
6551 Automake 1.5 chokes on dynamic source file lists, Besides, it is
6552 already listed in m4_LDADD... how did that ever used to work?
6553 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
6554 link.
6555 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6556 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
6558 * tests/m4: Don't call the m4 wrapper script with libtool, it
6559 works fine all by itself.
6561 2001-08-30 Gary V. Vaughan <gary@gnu.org>
6563 The experimental `changeword' feature never took off, and has
6564 no obvious advantages over `changesyntax' to compensate the
6565 enormous speed penalty it carries:
6566 * configure.in (ENABLE_CHANGEWORD): Removed.
6567 * m4/m4module.h (m4_set_word_regexp): Removed.
6568 * m4/m4private.h (m4_token_data): Removed original_text field.
6569 * m4/utility.c (m4_token_data_orig_text): Removed.
6570 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
6571 * m4/macro.c: Ditto.

6587 (ACLOCAL_MACROS): this.
6588 (list-standard-macros): Remove.

6593 In an attempt to moderate my egomania...
6594 * tests/modules.at: Remove attributions.
6596 * tests/generate.awk: When making substitutions to "@&t@", either
6597 "&" or "\&" in the substitution string argument to gsub refer back
6598 to the matched text. "@\\&t@" seems to work though, Tests 43 and
6599 67 now pass for me.
6601 2001-08-29 Akim Demaille <akim@epita.fr>
6603 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)

6614 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
6615 * tests/modules.at: here, new file.
6616 * tests/others.at, tests/generate.awk: Add a banner.
6617 * tests/testsuite.at: Adjust.
6618 (AT_CHECK_M4_FILTER): New, but unused.
6620 2001-08-29 Akim Demaille <akim@epita.fr>
6622 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
6623 handle that.
6624 * tests/others.at (wrap): Inline wrap.m4.
6625 (shadow): Inline shadow.m4.
6626 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
6627 * tests/m4: Simplify.
6629 2001-08-29 Akim Demaille <akim@epita.fr>
6631 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
6632 --language.
6634 2001-08-29 Akim Demaille <akim@epita.fr>
6636 * tests/generate.awk (normalize): s/@__@/@&t@/.
6638 2001-08-28 Akim Demaille <akim@epita.fr>
6640 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.

6644 * bootstrap (generate.awk): Generate test cases with new script.
6646 2001-08-27 Akim Demaille <akim@epita.fr>
6648 * tests/Makefile.am (installcheck-local): Don't use
6649 `dc_install_base' which is not visible here, but `exec_prefix'
6650 which is clearly the RT anyway.
6651 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
6652 related to testing a now installed m4.
6653 * tests/m4: Do it here.
6655 2001-08-27 Akim Demaille <akim@epita.fr>
6657 * tests/others.at (indir): Formatting change.
6659 2001-08-27 Akim Demaille <akim@epita.fr>
6661 * tests/Makefile.am (installcheck-local): New.
6662 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
6663 the test suite.
6664 Prefer options over envvars.
6665 * src/main.c (main): First bug caught by the test suite (yeah!):
6666 --batch lacked a `break' which resulted in an accidental
6667 invocation of --discard-comments.
6669 2001-08-27 Akim Demaille <akim@epita.fr>
6671 * tests/others.at (capitalize, changeword, comments, ddivert)
6672 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
6673 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
6674 (sysv-args, trace, translit, undivert): Don't rely on files in
6675 examples/: AT_DATA them.
6677 2001-08-27 Akim Demaille <akim@epita.fr>
6679 Let the test suite use a wrapper around the not installed m4 to
6680 pretend it is (installed).
6682 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
6683 such a way that m4 does not process them.
6684 * configure.in: The package name seems to be `m4', not `M4'.
6685 * tests/m4: New.
6686 * tests/atlocal.in (at_package, M4): Remove.
6687 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
6689 2001-08-27 Akim Demaille <akim@epita.fr>
6691 * tests/Makefile.am (CLEANFILES): Remove.

6695 2001-08-27 Akim Demaille <akim@epita.fr>
6697 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
6698 Don't use aclocal: it's written by hand.
6699 * aclocal.m4: m4_include all the files instead of being built by
6700 aclocal.
6701 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
6702 until it reads the traces by itself.
6703 * configure.in: Require Autoconf 2.42c as we are now using
6704 AC_CONFIG_TESTDIR instead of AT_CONFIG.
6705 Catch unexpanded `jm_' macros.
6706 * config/atconfig.m4: Remove.
6707 * config/error.m4: new.
6708 * config/Makefile.am: Ship the files included by aclocal.m4.
6709 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
6710 (TESTSUITE_AT): this, to please Automake.
6711 (TESTSUITE): This target uses autotest/autotest.m4, not
6712 autotest/general.m4.
6713 * tests/testsuite.at: Prereq Autotest 2.52c.
6714 * examples/Makefile.am (pkgdata_DATA): Rename as...
6715 (dist_pkgdata_DATA): this.
6716 * doc/Makefile.am (man_MANS): Rename as...
6717 (dist_man_mans): this.
6719 2001-08-20 Gary V. Vaughan <gary@gnu.org>
6721 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
6722 Robert Collins, building on Cygwin no longer requires Windows
6723 import and export symbol decorations.
6724 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
6725 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

6736 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
6738 2001-08-20 Gary V. Vaughan <gary@gnu.org>
6740 Ansify the source. Previously we had a mix, where my code was
6741 in a K&R compatible style, and the preexisting code was in ANSI
6742 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
6743 and now the code base is much cleaner.
6745 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
6746 VOID macro and all users.
6747 * m4/m4module.h: Ansify function prototypes and headers.
6748 * m4/builtin.c: Ditto.

6763 * src/main.c: Ditto.
6765 2001-08-20 Akim Demaille <akim@epita.fr>
6767 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
6768 generated with stock 2.52.
6770 2001-08-20 Akim Demaille <akim@epita.fr>
6772 * config/atconfig.m4: New, until part of Autoconf per se.

6775 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
6776 * tests/atlocal.in: New.
6777 * tests/generate.awk: For the time being, the empty quadrigraph is
6778 `@__@'.
6779 * tests/others.at (changeword, gmp): Check the configuration
6780 variable against `yes'.
6781 * tests/testsuite.at (dnl): Allow it, as it's used all over the
6782 place.
6784 2001-08-20 Akim Demaille <akim@epita.fr>
6786 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
6787 * modules/m4.c (undivert): Disable the possibility of undiverting
6788 several files at once: it is not documented, it is inconsistent
6789 with the other macros, it can be straightforwardly mocked by
6790 several invocations, and most importantly, it prevents the
6791 possibility of other kinds of extension.
6792 Use `m4_numeric_arg'.
6794 2001-08-20 Akim Demaille <akim@epita.fr>
6796 * examples/include.m4: Typo.
6797 * tests/generate.awk: Really add it.
6798 * tests/Makefile.am: Adjust.
6799 * tests/others.at (Discard comments): It sure fails without `-c'.
6800 (include, undivert): Add -I examples/.
6802 2001-08-20 Akim Demaille <akim@epita.fr>
6804 Use sprintf, not ecft and friends since it is standard, portable,
6805 simplifies the code, and since the latter is even deprecated
6806 according to the GNU libc documentation.
6808 * modules/format.c: Drop evct support.
6810 2001-08-19 Gary V. Vaughan <gary@gnu.org>
6812 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
6813 for `-pipe' here...
6814 * configure.in: ...do it here instead.
6816 * c-boxes.el: Deleted.
6817 * m4/builtin.c: Reformat box comments to be closer to GNU
6818 standards.

6862 * tests/Makefile.am (EXTRA_DIST): Ship generate.awk.
6863 (generate.at): Install a temporary hack until the actual
6864 generate.awk is added to the repository.
6865 * tests/atconfig.in: New.

6935 2001-08-17 Akim Demaille <akim@epita.fr>

6952 2001-08-17 Akim Demaille <akim@epita.fr>
6954 Drop Autoconf 2.13 compatibility.
6956 * configure.in (changeword): No need to undefine it, as anyway if
6957 it's defined, M4sugar moved it as m4_changeword.
6958 And anyway, proper quotation is enough.
6959 (m4_pattern_allow): As it exists in 2.50, just use it.
6960 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
6961 Don't handle Gettext's duties, let it handle them.

7015 (M4FINISH_HANDLER): And similarly for finish functions.

7018 correctly expanded.
7019 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
7020 * modules/shadow.c (m4_init_module): Ditto.

7026 finalisation only on first load.
7027 * m4/m4private.h (m4_module): Removed in favour of...
7028 (m4_module_data): ...structure without all the wrapper fields.
7029 Instances of this new structure are stored associated lt_dlhandles
7030 with lt_dlcaller_data_set().
7031 * m4/builtin.c (m4_builtin_define): Takes a handle argument
7032 instead of the old module argument.
7033 (m4_builtin_table_install): Ditto.
7034 * modules/load.c (m4_resident_module): Removed. This is no
7035 longer implemented as a magic symbol...
7036 * modules/m4.c (m4_resident_module): Ditto.
7037 * modules/load.c (M4INIT_HANDLER): ...the module init function now
7038 uses the ltdl api to make the module resident.
7039 * modules/m4.c (M4INIT_HANDLER): Ditto.
7040 * modules/load.c (builtin_modules): Traverse the loaded module
7041 list with lt_dlhandle_next.
7042 (builtin_load): Much simplified in light of the reimplemented
7043 module loader.
7044 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
7045 light of the m4/module.c rewrite.
7046 (produce_symbol_dump): Ditto.
7047 (reload_frozen_state): Ditto.
7048 * m4/list.c, m4/list.h: Files deleted. No longer required.
7049 * m4/Makefile.am (pkginc_HEADERS): Delete list.h reference.
7050 (libm4_la_SOURCES): Delete list.c reference.
7051 * m4/m4private.h (m4_token_data): Add a handle field. This
7052 eliminates many of the searches to find the handle associated with
7053 various tokens that are passed between functions.
7054 (struct m4_symbol): Removed the module field. The
7055 module association does not belong with the symbol...
7056 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
7057 that the module implementation code is from. Added a handle
7058 field.
7059 (m4_push_macro): Add a `handle' argument. Changed all callers.
7060 (init_macro_token): Set the `handle' field for the
7061 m4_token_data.
7062 * m4/macro.c (expand_argument): Copy the new handle field during
7063 reassignment.
7064 * modules/m4.c (macro_install): Use the new handle field to
7065 optimise the search for the correct builtin structure, and pass
7066 the handle details to m4_builtin_define.
7068 2001-08-15 Akim Demaille <akim@epita.fr>
7070 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
7071 when creating `m4/obstack.h'.
7072 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
7073 top_builddir.
7074 * tests/defs: Make them absolute.
7075 (CDPATH) Neutralize.
7076 * tests/gethem: Use them.
7078 2001-08-14 Gary V. Vaughan <gary@gnu.org>
7080 * config/ltmain.sh: Doh! Import again for a quoting fix that
7081 prevented any regression test from passing.
7083 * m4/m4module.h (obstack.h): Choose between installed version
7084 and shipped version based on configure tests.
7085 * src/freeze.c (obstack.h): Ditto.
7087 * acconfig.h: Removed. No longer required.
7089 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
7090 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
7091 them to AC_INIT and AM_INIT_AUTOMAKE.
7092 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
7093 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
7094 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
7095 shell variable m4_cv_func_obstack_h.
7096 * tests/defs (M4): Be more careful about relative path to libtool
7097 script and m4 binary by using $srcdir.
7099 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
7100 optargs to the existing libltdl search path.
7101 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
7102 * m4/ltdl.c: Updated.
7103 * m4/ltdl.h: Ditto.
7104 * config/ltmain.sh: Ditto.
7106 2001-08-11 Gary V. Vaughan <gary@gnu.org>
7108 * src/main.c (main): Add `-b' (for `batch') mode switch to force
7109 interactive mode off.
7111 2001-08-10 Akim Demaille <akim@epita.fr>
7113 * configure.in: Require Autoconf 2.52.
7114 (AC_ARG_PROGRAM): Remove, handled by Automake.
7115 (m4_getopt): Rename as...
7116 (m4_getopt_h): this.
7117 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
7118 Undefine `changeword' only if defined.
7119 * config/gnu-obstack.m4: Require Autoconf 2.52.
7120 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.
7121 Allow this token.
7123 2001-08-09 Yuji Minejima <ggb01164@nifty.ne.jp>
7125 * doc/m4.texinfo: Fix some typos, and apply some small
7126 clarifications.
7128 2001-08-09 Andreas Schwab <schwab@suse.de>
7130 * src/main.c (main): Fix improper uses of error (missing format
7131 string).
7133 2001-08-07 Akim Demaille <akim@epita.fr>
7135 Improve `make distcheck'.
7137 * configure.in: Be sure to be able to run `mkconfig.sh' when src
7138 != build.
7139 * Makefile.am (dist-hook): Remove, as it is no longer needed.
7140 * doc/m4.texinfo (Include): Add missing blank.
7141 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and
7142 obstack.c.
7144 2001-08-07 Akim Demaille <akim@epita.fr>
7146 * m4/evalparse.c: A better introductory comment.
7147 * m4/m4module.h (M4_DEBUG_PRINT2): s/M4_debug/m4_debug/.
7148 * m4/macro.c: Adjust old comments.
7149 * modules/README: Typo.
7151 2001-08-07 Akim Demaille <akim@epita.fr>
7153 * config/gnu-obstack.m4: New.
7155 2001-08-07 Akim Demaille <akim@epita.fr>
7157 * config/Makefile.am, config/stackovf.m4: New.
7158 * configure.in, Makefile.am: Adjust.
7160 2001-08-05 gettextize <bug-gnu-utils@gnu.org>
7162 * po/Makefile.in.in: Upgrade to gettext-0.10.39.
7163 * po/cat-id-tbl.c: Remove file.
7164 * po/stamp-cat-id: Remove file.
7166 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
7168 * modules/format.c (format): Formatting for %f was not
7169 interpreting the position of the decimal point correctly for
7170 whole numbers.
7172 2000-12-01 Gary V. Vaughan <gary@gnu.org>
7174 * TODO: Removed m4exit bug.
7175 * modules/load.c (m4_resident_module): Make this module resident.
7176 * module/m4.c (m4_resident_module): Ditto.
7177 * m4/modules.c (m4_module_load): Use new ltdl resident modules
7178 feature to mark modules as resident if they export
7179 `m4_resident_module' as TRUE.
7180 (m4_module_unload): Do not remove resident modules, and take care
7181 with symbol insertion and deletion with resident modules.
7182 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
7183 use resident modules feature.
7185 2000-11-30 Gary V. Vaughan <gary@gnu.org>
7187 * TODO: Updated. Removed some cruft that has since been fixed
7188 or implemented. Added some more entries.
7189 * NEWS: Updated.
7190 * README: Updated.
7191 * modules/README: Updated.
7192 * doc/m4.texinfo: Updated.
7194 * modules/gnu.c (builtin_functions): Make indir orthogonal to
7195 builtin, in that each is recognised as a macro only with parameters
7196 (builtin_indir): Passing 0 arguments is now an error, as with
7197 builtin.
7199 * src/main.c (usage): Added missing description of `-c' option.
7201 2000-11-29 Gary V. Vaughan <gary@gnu.org>
7203 Consolidate the myriad of dispersed test scripts into the
7204 tests subdirectory. I think I now have all the file where I
7205 want them, so there shouldn't be anymore upheaval =)O|
7206 Honest!
7207 * tests/Makefile.am: Updated to run the new tests added below.
7208 * tests/other-tests/capitalize.test, tests/other-tests/comments.test,
7209 tests/other-tests/ddivert.test, tests/other-tests/debug.test,

7223 tests/other-tests/unfrozen.m4, tests/other-tests/unload.test,
7224 tests/other-tests/wrap.test: New tests based on the contents
7225 of the tests removed below.
7226 * examples/Makefile.am, modules/Makefile.am: Updated to
7227 reflect removed tests.
7228 * examples/defs,modules/defs: Removed.
7229 * examples/capitalize.test, examples/comments.test,
7230 examples/ddivert.test, examples/debug.test,
7231 examples/esyscmd.test, examples/exp.test,

7242 modules/modpath3.test, modules/modpath4.test,

7244 modules/unfrozen.m4, modules/unload.test: Removed.
7246 Move the implementation of GMP support for the mpeval() builtin
7247 into a loadable module that depends on libgmp. mpeval() and
7248 eval() share a common parser, now in m4/evalparser.c; the code
7249 in m4/numb.c and m4/numb.h is now physically split between
7250 m4/eval.c (the eval() backend) and modules/mpeval.c (the
7251 mpeval() backend), rather than being differentiated by cpp
7252 macros and multiple inclusion. The mpeval module is always
7253 built but will generate an diagnostic if it is used from an
7254 installation that didn't link in the gmp library.
7255 * modules/Makefile.am: build and install the new mpeval module.
7256 * modules/mpeval.c: Now contains the former parts of m4/numb.c
7257 and m4/numb.h that are required for gmp support in mpeval().
7258 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
7259 * m4/evalmp.c: Removed.
7260 * m4/m4module.h: Removed conditional prototype for
7261 m4_mp_evaluate().
7262 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
7263 and m4/numb.h that do not rely on gmp.
7264 * m4/evalparse.c: New file, contains the shared parts of the
7265 eval() and evalmp() parser implementations, and is no longer
7266 unencumbered by cpp magic to uncover the right parts.
7267 * m4/numb.h: Removed. It's former contents are split between
7268 m4/eval.c and modules/mpeval.c.
7269 * m4/numb.c: ditto.
7271 * tests/other-tests/changeword.test: New test. Rudimentary
7272 testing of changeword builtin runs only if --wnable-changeword
7273 was used at configure time.
7274 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
7275 alternation correctly. Split into two expressions to compensate.
7276 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
7277 * modules/Makefile.am: Build changeword module.
7278 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
7279 only when --enable-changeword was passed to configure.
7280 (builtin_changeword): If --enable-changeword was not used, then
7281 report that changeword() builtin has no support in m4 binary.
7283 2000-11-28 Gary V. Vaughan <gary@gnu.org>
7285 * src/main.c (main): Fixed a particularly nasty bug is
7286 user_search_path setting -- the -M flag processing must be
7287 extremely careful with search path ordering, or else the default
7288 installed module directory (possibly containing modules from a
7289 previous release) is placed earlier in the search path than any -M
7290 arguments (which are relied upon to load uninstalled modules with
7291 most of the tests in the regresion suite).
7293 * modules/load.c (builtin_load): Nasty hack to prevent adding
7294 symbols to symtab again if a module is loaded more than once.
7295 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
7297 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
7298 possible NULL pointer dereference.
7300 * m4/module.c (m4_module_find_by_modname): Renamed from
7301 m4_module_modname_find. Fixed all references.
7302 (m4_module_find_by_builtin): New function.
7304 * modules/modfreeze.test: load the `load' module with each
7305 invocation.
7306 * src/freeze.c (produce_frozen_state): Simplified in light of
7307 module field in m4_symbol. Allow a third argument for text macros
7308 to name the originating module.
7309 (reload_frozen_state): ditto.
7310 * m4/m4module.h: Fixup prototypes.
7311 * m4/builtin.h (m4_builtin_define): Add a module argument so
7312 that symbols can be registered against the defining module.
7313 (m4_macro_define): ditto.
7314 * m4/m4private.h (m4_symbol): Make the module field const to save
7315 on casting in the rest of the code.
7316 (SYMBOL_MODULE): New macro.
7318 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
7319 symbol reference maintenance bugs when removing a symbol from the
7320 symtab.
7322 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
7324 2000-11-27 Gary V. Vaughan <gary@gnu.org>
7326 * configure.in (m4_cv_func_obstack): A better check for whether
7327 libc has an obstack implementation.
7328 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
7330 * configure.in (--with-modules): Changed semantics. This
7331 option is now used to list modules to be preopened.
7332 * src/m4.h: #include "ltdl.h" unconditionally.
7333 * src/main.c: Removed all dependencies on WITH_MODULES.
7334 * src/freeze.c: ditto.
7335 * modules/Makefile.am: ditto.
7336 * m4/m4.c (builtin_m4exit): ditto.
7337 * modules/modpath1.test: ditto.
7338 * modules/modpath2.test: ditto.
7339 * modules/modpath3.test: ditto.
7340 * modules/modpath4.test: ditto.
7341 * modules/modtest.test: ditto.
7342 * modules/shadow.test: ditto.
7343 * modules/unload.test: ditto.
7345 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
7346 comes up on demand in LTLIBOBJS now.
7347 * configure.in (getopt_long): Creating and relying on a link for
7348 getopt.h on hosts with no getopt_long() of thier own works
7349 correctly now. This is necessary so that callers of getopt_long()
7350 can simply `#include <getopt.h>': the naive way of doing this
7351 would end up using our own getopt.h and the installed
7352 getopt_long(), which is asking for trouble!
7353 (obstack_init): A similar argument applies to obstack.h and
7354 obstack_init().
7356 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
7357 On Solaris-2.5 (at least) the native dlopen implementation
7358 gets confused about m4.o when looking for module "m4". This
7359 version always looks for .la an .$lib_ext suffixed names first
7360 to work around the problem. Sigh.
7362 * po/POTFILES.in: Take account of these file movements.
7363 * src/Makefile.am (m4_SOURCES): removed eval.c.
7364 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
7365 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
7366 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
7367 * modules/m4.c (builtin_eval): Use m4_evaluate().
7368 * m4/eval.c: Moved here from src/eval.c to facilitate
7369 implementation of eval() builtin as part of the `m4' loadable
7370 module.
7371 (m4_evaluate): renamed from evaluate for namespace cleanliness.
7372 * m4/numb.c: Moved here from src/numb.c, since it is #included
7373 into eval.c at compile time.
7374 * m4/m4module.h (m4_evaluate): Added prototype.
7375 * src/m4.h (evaluate): Removed prototype.
7377 2000-11-25 Gary V. Vaughan <gary@gnu.org>
7379 * modules/perl.c (builtin_perleval): Use PL_na for
7380 compatibility with perl-5.6.
7382 * src/main.c (main): It is now safe to
7383 ``m4_module_install("m4")'', without tripping over the m4
7384 binary itself!
7385 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
7386 versions having fixed the insidious module search order bug.
7388 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
7389 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
7391 * configure.in: Figure out whether to use the installed
7392 getopt.h or the supplied one.
7393 * src/Makefile.am: ditto.
7395 * po/POTFILES.in: List files in their new positions.
7397 * config/ltmain.sh: This needs to be checked in to match the
7398 libtool macros copied to acinclude.m4 (until a released
7399 libtool copes with m4's needs).
7400 * bootstrap: Run gettextize.
7402 2000-11-24 Gary V. Vaughan <gary@gnu.org>
7404 * AUTHORS: Added my details.
7405 * TODO: updated.
7406 * NEWS: updated.
7407 * bootstrap: temporary update until released libtool catches up.
7409 * All files: Use new GNU GPL copyright blurb with current contact
7410 address.
7412 * configure.in (LTLIBOBJS): Use canonical code for calculation of
7413 this variable.
7415 * config: renamed acm4 directory to config to be more like
7416 other autoconfiscated packages.
7418 * configure.in (M4_AC_CHECK_DEBUGGING): Use it.
7419 * config/debug.m4: New file implementing configure macros to add
7420 suitable debug flags to the compiler invocation.
7422 * modules/load.c: New file implementing the ``load'' and
7423 ``unload'' builtins.
7424 * tests/get-them: Set the module search directory to the modules
7425 build directory in generated tests.
7426 * modules/shadow.test: ditto.
7427 * modules/modtest.test: ditto.
7428 * modules/modpath1.test: ditto.

7436 * modules/changeword.c: New file implementing the ``changeword''
7437 builtin as a loadable module.
7438 * modules/mpeval.c: New file implementing the ``mpeval'' builtin
7439 as a loadable module.
7441 * src/main.c (main): Load the gnu module if m4 was started
7442 normally -- i.e. without the -G option.
7443 * modules/gnu.c: New file implementing a new loadable module wuth
7444 definitions for all the gnu extension builtins.
7445 * modules/format.c: Moved here from src/format.c. Now included
7446 directly by gnu.c.
7448 * src/main.c (main): Load the traditional module if m4 was
7449 started in `no_gnu_extensions' mode.
7450 * modules/traditional.c: New file implementing the ``unix'' macro,
7451 required when m4 is executed in traditional mode, as a loadable
7452 module.
7454 * src/main.c: Renamed from m4.c to avoid confusion with
7455 modules/m4.c.
7456 (main): Always load the m4 module.
7457 * modules/m4.c: New file implementing a new loadable module with
7458 definitions for all m4 builtins that are not gnu extensions.
7460 * m4/Makefile.am: Adjusted to take new files below into account.
7461 * m4/m4module.h: Prototypes for exported functions and types moved
7462 to this directory from the src directory.
7463 * m4/m4private.h: Moved here from src/m4private.h to facilitate
7464 the migration of all builtin implementations to loadable modules.
7465 * m4/macro.c: Moved this file here from the src directory,
7466 renaming all exported symbols to use the prefix ``m4_''.
7467 * m4/builtin.c: ditto.
7468 * m4/module.c: ditto.
7469 * m4/symtab.c: ditto.
7470 * m4/debug.c: ditto.
7471 * m4/input.c: ditto.
7472 * m4/output.c: ditto.
7473 * m4/path.c: ditto.
7474 * m4/ltdl.h, m4/ltdl.c: ditto.
7475 * m4/utility.c: Odd functions moved here from files in the src
7476 directory to facilitate builtin migration.
7478 2000-08-12 Gary V. Vaughan <gary@gnu.org>
7480 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
7481 error message, to make translators' jobs a little easier.
7482 (builtin_builtin): ditto.
7483 (builtin_traceon): ditto.
7484 (builtin_traceoff): ditto.
7485 Reported by Akim Demaille <akim@epita.fr>

7729 increment serial number.
7731 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
7732 src dir and immediately after libm4 is built for confidence that
7733 it doesn't rely on the src directory.
7734 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
7735 makeinfo stop the build on cygwin (because they don't work).
7737 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
7739 * m4/m4private.h: ...is not a public header, so moved to src.
7740 Add `#include <config.h>', `#define _COMPILING_M4' and
7741 `#include "m4.h".
7742 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
7743 * src/Makefile.am (noinst_HEADERS): add m4private.h.

7766 m4/libm4.la.
7767 * m4/m4error.h: Renamed error.h, for installation to

7783 From Akim Demaille <akim@epita.fr>
7785 2000-01-17 Gary V. Vaughan <gary@gnu.org>
7787 * src/ltdl.c: Use access() to abort doomed module load attempts
7788 if module file does not exist.
7790 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
7791 getopt1.o will already be used if appropriate, so I moved getopt.c
7792 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
7794 * modules/modpath1.test: Use correct filename in header line.
7795 * modules/modpath2.test: ditto.
7796 * modules/modpath3.test: ditto.
7797 * modules/modpath4.test: ditto.
7799 Without these changes lt_dlopen("test") attempts to
7800 LoadLibrary("/bin/test") on Windows, which although harmless
7801 generates a spurious error message which spoils most of the tests:
7802 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
7803 (TESTS): s/test.test /modtest.test /
7804 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

7808 * modules/modpath4.test: ditto.
7809 * modules/modpath3.test: s/-m test /-m modtest /
7810 * modules/shadow.m4: use {un,}loadmodule(`modtest').
7812 2000-01-16 Gary V. Vaughan <gary@gnu.org>

7827 Treats -M and -m as the arguments -D -U and -t, ie deferred.
7829 * src/m4.h: Added declaration of module_init().
7831 * src/module.c (module_init): No longer static
7833 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
7834 Added to shut up automake about non standard libtool library
7835 names.
7837 * src/module.c: Disabled DEBUG by default.

7850 * doc/help2man.pl: updated to version 1.020.
7852 * lib/COPYING.LIB: updated to version 2.1.
7854 * lib/m4module.h: restructure the M4_SCOPE code to work when
7855 creating a dll which links with libm4.la and both DLL_EXPORT
7856 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
7857 both defined.
7859 2000-01-11 Gary V. Vaughan <gary@gnu.org>
7861 Merged the following changes from my tree:
7863 1999-06-15 Gary V. Vaughan <gary@gnu.org>
7865 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
7866 ported to compile shared libs.
7868 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
7869 use `__declspec(dllimport)' when linking libm4.la on win32.
7870 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
7872 * configure.in (M4OBJS): Discover whether we need the shipped
7873 implementation of getopt_long.
7874 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
7875 main binary here, as opposed to the module library in lib/libm4.la.
7877 1999-06-14 Gary V. Vaughan <gary@gnu.org>
7879 * modules/README: Updated to describe the improved libltdl based
7880 module scheme.
7881 * README (cygwin): Added some compilation notes for building m4
7882 correctly under cygwin.
7883 * TODO: Cleaned out the entries for the module system since they
7884 are now implemented.
7886 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
7887 all instances of __P with M4_PARAMS.
7889 * lib/getdate.h: removed unreferenced file.
7891 * lib/m4private.h: New file to define the private interface to the
7892 token_data struct, which must be shared between m4module.c, and
7893 builtin.c but not exported to modules built from the installed
7894 m4module.h since it's size changes depending on compile time
7895 options.
7897 * src/m4.h: Lots of stuff moved to lib/m4module.h.
7899 * lib/m4module.h: New file to define the interface available when
7900 compiling m4 modules.
7901 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
7902 necessary for module compilation into this new file.
7904 * lib/Makefile.am (include_HEADERS): install headers (renamed to
7905 avoid nameclash with other system headers) necessary for compiling
7906 modules.
7907 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
7908 so that modules can include the (renamed) installed headers and
7909 be guaranteed a matching implementation.
7910 * lib/m4error.h: renamed from error.h.
7911 * lib/m4obstack.h: renamed from obstack.h.
7912 * lib/m4regex.h: renamed from regex.h.
7913 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
7914 implementation, simply include the shipped version
7915 unconditionally, otherwise it is hard for a module to know
7916 whether the m4obstack.h header it is using matches the
7917 implementation it ends up linking against.
7918 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
7919 the same reason.
7921 1999-05-18 Gary V. Vaughan <gary@gnu.org>
7923 * examples/misc.test: Don't run this test on machines which don't
7924 have a root user in /etc/passwd (e.g. cygwin).
7926 * tests/get-them (/^@example$/): Error messages might have a
7927 ``.exe'' suffix to the program name, or else use the libtool
7928 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
7929 of these cases are now catered for when comparing error messages
7930 in generated tests.
7931 * tests/other-tests/*.test: ditto.
7932 * examples/*.test: ditto.
7934 * tests/defs (M4): use libtool execute mode.
7935 * examples/defs (M4): ditto.
7937 * tests/get-them (END): explicitly close any open file.
7938 (printthem): In a regular expression, '{' is the start of a repeat
7939 count! Use `[{]' for a literal open brace.
7940 (/^@node /): Don't use substr on a string shorter than the trim
7941 length.
7943 1999-05-17 Gary V. Vaughan <gary@gnu.org>
7945 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
7946 substituted.
7947 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
7949 2000-01-10 Andreas Schwab <schwab@suse.de>
7951 * tests/other-tests/gmp.test: Find config.sh in build directory.
7953 * configure.in: Find tests/mkconfig.sh in $srcdir.
7955 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
7956 <signal.h> (for SUS2 compliant systems).
7958 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
7959 HAVE_SIGINFO_H.
7961 2000-01-10 René Seindal <rene@seindal.dk>
7963 * Prerelease 1.4o.
7965 * TODO, NEWS: Cleaned up and updated.
7967 * src/m4.c (main): New variable exit_status for exit status in
7968 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
7969 file cannot be read instead of EXIT_SUCCESS.
7971 * src/builtin.c (m4_indir): Changed error message to help
7972 translators (from Akim Demaille <demaille@inf.enst.fr>).
7974 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
7975 Cygnus.
7977 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
7978 from glic 2.1.2.
7980 * src/input.c (match_input): Reordering of code, to avoid multiple
7981 calls to push_string_init() from obstack_grow(), which can happen
7982 with some compilers (found and fixed by James Bonfield
7983 <jkb@mrc-lmb.cam.ac.uk>).

7992 quotes when the old quote is a part of the new.
7994 * src/builtin.c (expand_ranges): Added break after trailing dash.
7995 This caused misbehavious on some systems (found and fixed by Akim
7996 Demaille <demaille@inf.enst.fr>).
7998 * AUTHORS: Thomas Tanner included
8000 * acconfig.h: Added entry for ss_sp (see below).
8002 * configure.in (use_stackovf): Added check for stack_t with member
8003 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert

8034 * src/m4.c: Don't need to include error.h.
8036 1999-11-09 Paul Eggert <eggert@twinsun.com>
8038 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
8039 and zero, as Solaris 7 cc does.
8040 (bcopy): Remove macro; no longer needed with new obstack.h.
8042 * src/output.c (freeze_diversions): Don't assume that a
8043 diversion size can fit in `int'. Check for diversion file
8044 size too large to be printed with `unsigned long'.
8046 * src/Makefile.am (CFLAGS): Omit -Wall.
8048 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.

8079 are modules, not linktime libraries.
8080 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
8081 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
8082 avoidance on exported symbols.
8083 * modules/test.c (m4_macro_table, m4_init_module,
8084 m4_finish_module): ditto.
8085 * modules/time.c (m4_macro_table): ditto.

8088 of modules.
8089 * src/m4.c (--load-module): dynamically load named runtime module
8090 into running executable before reading the source.
8091 (--module-directory): prepend a directory to the module search
8092 path.
8093 (module_init()): Do this the first time we load a module instead;
8094 if the module subsystem is broken normal m4 scripts can still run.
8095 * src/m4.h (install_builtin_table): is now exported.
8097 1999-03-26 Gary V. Vaughan <gary@gnu.org>

8114 better.
8115 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
8116 * acm4/gettext.m4: removed. It causes a multiple definition vs.
8117 the installed gettext.m4 file when running aclocal.
8119 1999-03-25 Gary V. Vaughan <gary@gnu.org>
8121 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

8123 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
8124 in its own subdirectory.
8126 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no

8131 (module_unload_all): use libltdl.
8132 * src/m4.c (module_init): initialise module loading on demand for

8140 * modules/time.c (m4_macro_table): ditto.
8142 * bootstrap: New file. Runs all the autoutils in the right order
8143 after a fresh checkout, or a make maintainer-clean.
8145 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
8147 * src/builtin.c (dump_symbols): New function, factoring common
8148 content of m4_dumpdef and m4_symbols.
8149 (m4_dumpdef): Use it.
8150 (m4_symbols): New function, implementing `symbols'. Use it.
8151 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
8152 file compile with modern makeinfo.
8153 (Symbols): New node, documenting symbols.
8154 (direntry): Modernize.
8156 1998-12-11 René Seindal <rene@seindal.dk>

8160 configure time options.
8162 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
8164 * src/module.c (module_try_load): Don't try to be clever and
8165 overwrite argument string. Instead allocate all constructed
8166 strings locally, since they can have arbitrary lengths. Make
8167 arguments pointers to const.
8168 (module_search): Simplify due to above change.
8170 1998-11-29 René Seindal <rene@seindal.dk>

8187 Added declaration of discard_comments.
8189 * src/input.c (next_token): Now loops until token type is not
8190 TOKEN_NONE. Comments are now given this type when comments should
8191 be discarded.

8194 and mpeval.
8196 1998-11-28 René Seindal <rene@seindal.dk>
8198 * src/m4.c (main): New option --import-environment (no single
8199 letter option).
8201 * When configured with --with-gmp both the normal (fast) eval()
8202 and the gmp aware mpeval() are defined. To restore previous
8203 bahaviour use "define(`eval', defn(`mpeval'))".
8205 * tests/other-tests/gmp.m4: Changed to use mpeval().
8207 * src/evalmp.c: New file for compiling eval.c as gmp aware.
8208 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
8210 * src/eval.c: Now includes "numb.c" directly. Everything in this
8211 file must by static, except evaluate(), which is changed to
8212 mp_evaluate() if USE_GMP in force.
8214 * src/numb.c: Changed to be included by eval.c instead of being
8215 compiled separately. Everything is declared static.
8217 * src/numb.h: Removed declarations of functions, as numb.c is now
8218 included by eval.c.
8220 * src/builtin.c: Declaration of m4_mpeval() added.
8221 Inserted `mpeval' in builtin table.
8222 (do_eval): New function with common code for m4_eval and m4_mpeval.

8225 * src/m4.h: Declaration of mp_evaluate().
8227 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
8228 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
8230 * src/m4.c (main): m4 --version also shows which options were used
8231 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
8233 1998-11-27 René Seindal <rene@seindal.dk>
8235 * Error messages now always print program name before input file
8236 name as specified by GNU coding standards. Reported by Akim
8237 Demaille <demaille@inf.enst.fr>.
8239 * doc/m4.texinfo (Include): Change due to changed error message
8240 format.
8241 (Eval): Do.
8243 * tests/get-them: Minor change to sed script due to changed error
8244 message format.
8246 * src/m4.c (print_program_name): New func used to print program
8247 name, input file and line number in error (). Used as an
8248 error_print_progname handler.

8250 (main): Assigns error_print_progname.
8252 * src/m4.h (M4ERROR): Removed reference_error ().
8254 1998-11-25 René Seindal <rene@seindal.dk>
8256 * Updated to libtool 1.2b.
8258 * src/builtin.c (install_builtin_table): Added braces to avoid
8259 warning of ambiguous 'else'.
8261 * src/module.c: Inserted search path code from path.c modified to
8262 use new interface.
8263 (module_init): Configured default path used only if M4MODPATH is
8264 not set.
8265 (module_try_load): Now reads libMODULE.la as generated by libtool
8266 for actual module name.
8267 (module_load): Gives better error messages on failure.
8269 * src/m4.h: Added declarations of structures and functions for
8270 generic search path handling.
8272 * src/path.c: Removed all module specific code and introduced new
8273 functions of more generic search path handling.
8275 1998-11-24 René Seindal <rene@seindal.dk>
8277 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
8278 included gettext, as <libintl.h> might not be found
8279 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
8281 1998-11-22 René Seindal <rene@seindal.dk>
8283 * src/output.c (insert_diversion): Fixed bug that might cause m4
8284 to read from standard output! Triggered by input
8285 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
8286 so now 'undivert(0)' does nothing.
8288 1998-11-18 René Seindal <rene@seindal.dk>
8290 * Prerelease 1.4m.
8292 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp

8297 standards.
8299 * src/m4.c (usage): Added message about reporting bugs.

8310 with libtool.
8312 * modules/Makefile.am: Changed completely to compile modules using
8313 libtool. The modules are compiled as shared libraries, and are
8314 renamed when installed.
8316 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
8317 USE_SHL_LOAD to HAVE_SHL_LOAD

8321 * src/module.c: New level of indirection around non-portable
8322 functions to load shared objects. Intended to encapsulate the non
8323 portable parts better and to reduce the number of #ifdefs in the
8324 code.
8326 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
8327 directory modules/ to the distribution.
8329 1998-11-15 René Seindal <rene@seindal.dk>

8337 * src/builtin.c (shipout_string): New convenience function for
8338 builtins and modules.
8340 * src/module.c (module_load): Tentative support for
8341 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.

8345 * modules/Makefile.am: Now correctly compiles and installs
8346 modules in pkglibexecdir.
8348 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
8349 These two are now initialised by autoconf macros.
8351 * src/path.c (module_env_init): MODULE_PATH is always on the
8352 search path.
8354 * src/Makefile.am: Now generated pathconf.h which defined the
8355 default MODULE_PATH.
8357 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
8358 where modules are installed.
8360 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
8361 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
8362 build and install automatically, and it is prepared for other
8363 interfacec than dlopen().
8365 * src/builtin.c (predefined_tab): Added __m4_version__ for the
8366 current version of GNU m4. It is a GNU extension.

8536 tests/ directory.
8538 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
8539 directory. The files stay there but the tests are run from the
8540 tests/ directory.
8542 * tests/Makefile.am (EXTRA_DIST): Added run-test.
8544 * tests/run-test: New file. Run a test manually
8546 * tests/Makefile.am, tests/get_them: Moved automatically generated
8547 tests (from the manual) to sub directory tests/gentest/. The
8548 tests/ directory had gotten a bit messy.
8550 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8552 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
8553 wrap}.test: Added a few testcases.
8555 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8557 * Prerelease 1.4h.
8559 * lib/Makefile.am (noinst_HEADERS): regex.h added
8561 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
8562 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
8564 * acm4/Makefile.am: created providing rules to create
8565 $(top_srcdir)/acinclude.m4 to be used by aclocal.
8567 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
8568 `C'. Reported by Ulrich Drepper.
8570 * Makefile.am (SUBDIRS): Removed checks directory
8571 * configure.in (AC_OUTPUT): Removed checks/Makefile
8573 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
8574 the space when m4.texinfo is edited and whitespace.el is active.
8575 (Defn,example): idem.
8577 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8579 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
8580 ../COPYING. ../Makefile is a file which is certainly present when
8581 test is executed in testSubDir. One can't be sure that the COPYING
8582 file is in .. or ../.. in all situations, the ../Makefile is
8583 always there.
8585 * doc/m4.texinfo (Include): adjusted expected test output
8586 according to new tests, i.e. the input will always come from the
8587 file `in' created by the test.
8589 * tests/Makefile.am: Added three lines at the top to get
8590 esyscmd.1.test working.
8592 * tests/get-them: modified to generate clearer tests who will need
8593 less maintenance when new test examples are created in
8594 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
8595 need the generic file `defs') shell scripts creating `in', `ok',
8596 `out' and when apropriate `okerr' and `err' in the directory
8597 `testSubDir' when executed. The compare of `ok' and `out'
8598 (and of `okerr' and `err') will be the exit status of the test.
8599 `out' must match `ok' (and `okerr' must match `err') for the test
8600 to be succesful.
8602 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
8603 the tests generated by tests/get-them getting it input normally
8604 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
8605 (dot) before the numeric part) is reserved for all other (hand
8606 written) tests. The `+' means one or more times.
8608 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8610 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
8611 supported short man page to refer to info documentation
8612 * helptoman.pl: added
8613 * configure.in: AC_PATH_PROG(PERL,perl)
8614 * Makefile.am (SUBDIRS): doc after src
8616 * libitized with libit 0.5 from
8617 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.
8619 * configure.in (AC_REPLACE_FUNCS): added xmalloc xstrdup
8620 * lib/Makefile.am (libm4_a_SOURCES): removed automakely supported
8621 replacement functions, (libm4_a_LIBADD): @LIBOBJS@
8622 * configure.in (AM_WITH_REGEX), acconfig.h (WITH_REGEX): added
8623 lib/rx.{c,h}: added
8624 * configure.in (AC_CHECK_FUNC): getopt_long
8626 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
8628 * TODO: added entry about dependencies

8632 * Prerelease 1.4f
8634 * doc/m4.texinfo (Changesyntax): Added documentation for the macro
8635 "changesyntax".
8637 * src/builtin.c (m4_changesyntax): Added builtin macro
8638 "changesyntax" to modify the syntax table.
8640 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax

8644 1998-08-09 René Seindal <rene@seindal.dk>
8646 * src/numb.{c,h}: New files, implements multiple precision eval
8647 using GNU gmp. Originally submitted by John Gerard Makecki
8648 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.

8659 of comment and quote strings to `unsigned int' to allow eight bit
8660 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
8662 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
8663 patch from Mike Howard <mike@clove.com>
8665 1998-08-06 René Seindal <rene@seindal.dk>
8667 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

8702 mkinstalldirs, install-sh: Added automake (1.3) support.
8704 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
8705 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:

8760 be opened, return immediately after producing the error message.
8761 Reported by Andreas Schwab.
8763 * configure.in: Check for const only after having found possible
8764 ANSIfying compiler flags, this is of no use to check it before.
8765 Reported by Alexander Lehmann.
8767 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
8769 * src/macro.c (collect_arguments): Cast obstack arguments to
8770 (voidstar), so avoiding compiler warnings.
8771 Reported by Joseph E. Sacco.
8773 * src/freeze.c (produce_frozen_state): Cast printed lengths to
8774 (int) so they correspond to %d format items.
8775 Reported by Joseph E. Sacco.
8777 * src/m4.c (main): Cast the argument to xfree to (voidstar).
8778 * src/symtab.c (free_symbol): Idem.

8812 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
8813 Remove the sed filter after ansi2knr for debug.c. Use $O instead
8814 of $U, put underline in extensions rather than in basenames. Use
8815 implicit rules, now that regularity makes this possible.
8816 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
8817 of ansi2knr whenever it is needed.
8818 * configure.in: Adjusted for correct STACKOVF substitution.
8819 * src/debug.c (trace_format): When not __STDC__, use (...) as a

8838 * {,/*}Makefile.in: Use && after all cd, in case they fail.
8840 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

8866 Reported by Jim Meyering.
8868 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
8870 * src/stackovf.c: Declare the handler_t typedef earlier in the

8872 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
8873 casting sigsegv_handler.
8874 Reported by Robert Bernstein.
8876 * src/m4.c (main): Initialize program_name to argv[0] without

8903 * Makefile.in (distclean, realclean): Instead of recursively
8904 calling $(MAKE) for the -local part, allow parallel execution of

8910 * Release 1.3.
8912 * Makefile.in: Group all *clean-recursive goals in one, using sed

8918 Reported by Kaveh R. Ghazi.
8920 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
8921 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
8922 specify it.
8924 * configure.in: Use date instead of touch for stamp-h.
8925 * Makefile.in (stamp-h.in): Idem.
8927 * Makefile.in (distclean, realclean): Force serial execution of
8928 both goals, in case parallel makes are being used.

8955 Reported by Jim Meyering.
8957 1994-09-06 François Pinard <pinard@iro.umontreal.ca>

8980 calling a function by that name. Declare the variable.
8981 * src/m4.h: Adjust declaration for prefix_all_buitins.
8982 * src/builtin.c (builtin_init): Merge in functionality from
8983 previous prefix_all_buitins function, while making entries in the
8984 symbol table, but not modifying the builtin description itself.
8986 * src/freeze.c (reload_frozen_state): Add a useless `break;',
8987 because *many* compilers do not accept an empty `default:'.

8989 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
8991 * configure.in: Use AC_TYPE_SIGNAL.
8992 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.

8998 Reported by Akiko Matsushita and Jim Meyering.
9000 * src/output.c (make_room_for, output_character_helper): New
9001 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
9002 a per buffer MAXIMUM_BUFFER_SIZE.
9004 * src/output.c (output_text): New function, for optimizing the

9013 * configure.in: Configure new Makefiles.
9015 * m4.h: Declare STRING typedef. Use it for comment and quote
9016 strings, adjusting all references. (This is the rudiments of a
9017 beginning for the eventual withdrawal of NUL terminated strings.)
9018 * output.c (shipout_text): Accept a length parameter, and use it.
9019 All callers adjusted.
9021 1994-08-29 François Pinard <pinard@iro.umontreal.ca>

9047 reload them properly.
9048 * m4.c: Do not undivert automatically at end when status being
9049 frozen. Do not call builtin_init when reloading frozen state.
9051 Speed up diversion processing:
9052 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
9053 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion

9061 1994-08-28 François Pinard <pinard@iro.umontreal.ca>
9063 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
9064 dist works from another build directory.
9066 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
9068 * symtab.c (hack_all_symbols): Use hash_table_size instead of
9069 constant HASHMAX, for -H option to work better.
9071 * builtin.c (DECLARE): Simplify by using _ ().
9073 * freeze.c: New file.
9074 * Makefile.in: Compile it, distribute it.
9075 * m4.c: Recognize, document and process --freeze-state (-F) and
9076 --reload-state (-R) options. Pass a true flag to builtin_init
9077 only if no reloading some state.
9078 * builtin.c (define_builtin): Remove static specifier.
9079 (find_builtin_by_name): Remove static specifier.
9080 (builtin_init): Accept and obey a flag argument.
9081 * m4.h: Add declarations for freeze.c, changes for builtin.c.
9083 1994-08-24 François Pinard <pinard@iro.umontreal.ca>
9085 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
9086 specifier.
9088 * configure.in: Implement --with-dmalloc.
9089 * acconfig.h: Document WITH_DMALLOC.
9090 * m4.h: Add code for when WITH_DMALLOC.
9092 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
9094 * m4.c (long_options): Use "error-output", the dash was missing.
9095 Reported by Akiko Matsushita.
9097 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
9099 * m4.h: Include <sys/types.h>.
9100 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
9101 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
9102 int.
9103 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
9104 as size_t, not int.
9105 * builtin.c (dump_args): Declare len as size_t, not int.
9107 * debug.c: Prototype the forward declaration of debug_set_file.
9109 * builtin.c (m4_undivert): Replace div by file, for avoiding the
9110 shadowing of this variable.
9111 * output.c (insert_diversion): Idem.
9113 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
9114 (input_init): Duplicate default quote and comment strings.
9115 (set_quotes): Free previous quote strings in all cases. Duplicate
9116 even default quote strings.
9117 (set_comment): Free previous comment strings in all cases.
9118 Duplicate even default comment strings.
9120 * configure.in: Updated for Autoconf 2.0.
9121 * Makefile.in (distclean-local): Also delete config.cache.
9123 * m4.c (usage): Reorganize the --help output by topic. Include a
9124 description for debugging flags.
9126 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
9128 * configure.in: If sigaction is available and SA_ONSTACK defined,
9129 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
9130 defined, use sigvec. Else don't compile stackovf.c.
9131 * stackovf.c (setup_stackovf_trap): Idem.
9132 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
9133 and Simon Leinen.
9135 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
9137 * m4.c (usage): Replace printf par fputs.
9138 \f
9139 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
9141 * Release 1.2
9143 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
9145 * configure.in: Check for sigaction and sigvec. Add a new delayed
9146 check for RLIMIT_STACK, combine in the checking for getrlimit.
9147 All those things are not universally available.
9148 * stackovf.c: Split setting up the trap handler and catching
9149 signals, for better taking care of various configure outcomes.
9150 * examples/stackovf.sh: Correct a typo.
9151 Reported by Eric Backus, Jim Avera and Jim Meyering.
9153 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
9155 * ansi2knr.c: New version sent by its author, Peter Deutsch.
9157 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
9159 * Makefile.in: Modify so parallel make will not try making
9160 lib/libm4.a twice simultaneously.
9161 Reported by Jim Meyering.
9163 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
9165 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
9166 error message, for when no code possibility exists. Even if this
9167 line is completely #ifdef'ed out, it brings a syntax error.
9168 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
9170 * Makefile.in (install): Have install depend on all too, for lib
9171 to be remade as needed.
9173 * examples/stackovf.sh: Try ksh, bsh and bash for shells
9174 providing ulimit, instead of using only ksh.
9175 Reported by Jim Avera and Joseph E. Sacco.
9177 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
9179 * Makefile.in (check): Have it depend on all instead of m4. In
9180 this way, a change in lib will be detected and processed.
9182 * builtin.c (numeric_arg): Use strtol and verify the conversion,
9183 instead of using sscanf which stops as soon as there is a
9184 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
9185 and divert(1xyzzy) were all accepted without any warning or error
9186 messages.
9187 * m4.h: Declare strtol as long if not including stdlib.h.
9188 * configure.in: Check for limits.h, and replace strtol if missing.
9189 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
9190 * lib/strtol.c: New file, from elsewhere.
9191 Reported by Andreas Schwab.
9193 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
9195 * macro.c (expand_macro): Cast value to (boolean) prior to
9196 assigning it to traced.
9197 Reported by Tom McConnell.
9199 * Makefile.in (m4): Always make all in lib first.
9200 Reported by Jim Meyering.
9202 1994-07-06 Jim Avera <jima@netcom.com>
9204 * stackovf.c: Isolated OS-dependent sections; Improved portability,
9205 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
9206 handlers), and a default error message if the fault address is not
9207 available (when neither siginfo.h nor BSD sigcontext are supported).
9208 * configure.in: Changes for stackovf.h: Check for sigcontext,
9209 sigaction, sigstack, and define rlim_t as int if necessary.
9210 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
9211 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
9212 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
9214 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
9216 * configure.in: Use AC_SET_MAKE.
9217 * Makefile.in: Use @SET_MAKE@.
9218 Reported by Jim Meyering.
9220 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
9221 Reported by Ian Taylor.
9223 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
9225 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
9226 because siginfo.h is unrelated to standard headers, and siginfo.h
9227 is already checked for.
9228 Reported by Joseph E. Sacco.
9230 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
9231 PROTOTYPES.
9232 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
9233 AC_PROTOTYPES.
9235 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
9237 * builtin.c (substitute): Use \& to represent this part of the
9238 string which was matched by the whole regexp, instead of
9239 representing the whole string. Any usage of \0 issues a warning
9240 and acts like \&, it will disappear in some subsequent release.
9242 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
9244 * m4.c: Complete prototype for forwarded declaration of usage.
9246 * input.c (init_macro_token): Correct own reference in error
9247 message. Previous name get_macro_func was referred to instead.
9248 (next_char): Correct own reference in error message. Previous
9249 name advance_input was referred to instead.
9251 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
9252 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
9253 and_term, not_term, logical_not_term, cmp_term, shift_term,
9254 add_term, mult_term, exp_term, unary_term, simple_term): Add
9255 prototype to forwarded declarations. Declare parameter v1 as
9256 eval_t * instead of int *. Same for local variable v2 in dyadic
9257 functions. Same for result in exp_term.
9258 * builtin.c (m4_eval): Declare value as eval_t instead of int.
9259 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
9260 unsigned_eval_t instead of unsigned int. Change casts accordingly.
9261 (shipout_int): Cast first argument of ntoa to eval_t.
9262 Reported by Thorsten Ohl.
9264 * macro.c: Complete the prototypes of forwarded expand_macro and
9265 expand_token.
9266 Reported by Thorsten Ohl.
9268 * m4.h: Define voidstar as void * or char * depending on __STDC__.
9269 The Ultrix 3.1 compiler cannot do much with void pointers.
9271 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
9272 * m4.c (xfree): Replace void * by voidstar.
9273 Reported by Tom McConnell.
9275 * ansi2knr.1: New, from elsewhere.
9276 * Makefile.in (DISTFILES): Distribute ansi2knr.1
9278 * Makefile.in (stamp-h.in): Avoid running ./config.status if
9279 stamp-h does not exist yet. This avoids running it a second time
9280 just after the initial ./configure.
9281 Reported by David MacKenzie and Tom McConnell.
9283 * m4.h: Replace the enum debug_info declaration with a series of
9284 #define's. The Ultrix 3.1 compiler would otherwise need casting
9285 (int) to most references, when used in expressions.
9286 Reported by Tom McConnell.
9288 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
9290 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
9291 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
9292 calls the compiler. Previously, FP_PROTOTYPES was only calling
9293 the preprocessor; by not being subject to CFLAGS, this was
9294 discouraging those flags asking for ANSI compilation.
9295 * acconfig.h: Document HAVE_PROTOTYPES.
9296 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
9297 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
9298 Reported by Eric Backus.
9300 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
9301 from the environment. Default CFLAGS to -g if not set.
9302 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
9303 * lib/Makefile.in: Have CFLAGS substituted from configure.
9304 Reported by Eric Backus and Tom McConnell.
9306 * configure.in: m4_undefine changeword before using AC_ENABLE.
9308 * m4.h: Declare prototypes for error (for ANSI compilers only),
9309 prefix_all_builtins and reference_error.
9310 Reported by Tom McConnell.
9312 * input.c (set_word_regexp): Do not try to initialize the array
9313 test from a string, this does not work with non-ANSI compilers.
9314 Reported by Eric Backus.
9316 * Makefile.in (dist): Clean examples/ before saving it.
9317 (distclean-local): Also remove stamp-h.
9318 Reported by Eric Backus.
9320 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
9321 non ANSI compilers.
9322 Reported by Tom McConnell.
9324 * checks/Makefile.in (clean): Depends on mostlyclean.
9325 (mostlyclean): New goal.
9327 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
9329 * Makefile.in (DISTFILES): Distribute install.sh.
9330 * install.sh: New file, copied from elsewhere.
9331 Reported by Assar Westerlund and Kaveh R. Ghazi.
9333 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
9335 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
9336 * acconfig.h: Explain ENABLE_CHANGEWORD.
9338 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
9339 from code provided by Pete Chown]
9340 * m4.h: Add original_text field to u_t variant of union u.
9341 Declare TOKEN_DATA_FUNC macro.
9342 * builtin.c: Declare changeword.
9343 (m4_changeword): New function.
9344 * input.c: Include "regex.h", define variables with word regexps.
9345 (input_init): Initialize the word regexp.
9346 (set_word_regexp): New.
9347 (next_token): Declare local variables, use the previous code if
9348 default_word_regexp is true. Else, match using a new code. Save
9349 the original text.
9350 * macro.c (expand_token): Ship out original text if not a macro
9351 name.
9352 Reported by Krste Asanovic and Pete Chown.
9354 [These modifs all depend upon ENABLE_CHANGEWORD]
9355 * m4.h: Declare external user_word_regexp.
9356 * m4.c: Declare user_word_regexp, and initialize it from
9357 --word-regexp or -W, or NULL if not specified.
9358 * input.c: Use user_word_regexp if specified, instead of
9359 DEFAULT_WORD_REGEXP.
9361 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
9362 agree with it.
9364 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
9365 * checks/Makefile.in: Empty the suffix list.
9366 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
9368 * m4.c: Declare nesting_limit and initialize it to 250.
9369 Implement -LNUMBER or --nesting-limit=NUMBER to change its
9370 value.
9371 * m4.h: Declare nesting_limit as external.
9372 * macro.c (expand_macro): Stop execution whenever nesting limit
9373 is exceeded.
9374 Reported by Bengt Mertensson.
9376 * eval.c (evaluate): Diagnose excess characters in eval input.
9377 Things like `eval(08)' used to return 0 with no diagnostic.
9379 * m4.h: Capitalize first letter of all macro arguments in
9380 definitions.
9382 * m4.c: Declare warning_status, initialize it to 0. Add new
9383 option -E, or --fatal-warnings, which sets warning_status to
9384 EXIT_FAILURE instead.
9385 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
9386 EXIT_FAILURE if not otherwise done by header files.
9387 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
9388 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
9389 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
9390 argument of all M4ERROR calls.
9391 Reported by Noah Friedman.
9393 * examples/incl-test.m4: Renamed from incl_test.m4.
9394 * examples/include.m4: Include incl-test.m4 instead of
9395 incl_test.m4.
9396 * examples/multiquotes.m4: Renamed from multi-quotes.m.
9398 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
9400 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
9401 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
9402 also tested it on a Sun Sparc workstation running SunOS 4.x.
9404 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
9405 49.format check, abusing a `union values' argument with sprintf
9406 without selecting the proper field. Now, save the formatting type
9407 first, delaying the fetch of the corresponding argument.
9408 Reported by Joseph E. Sacco and Tom Quinn.
9410 * format.c (format): Remove const from char *fmt declaration when
9411 not HAVE_EFGCVT, because a NUL may be forced into it.
9413 * m4.h: Declare atof() when not STDC_HEADERS.
9414 Reported by Joseph E. Sacco.
9416 * Regenerate configure using Autoconf 1.11, this corrects a
9417 problem about an incorrect cpp seting on NeXT 3.1.
9418 Reported by Alexander Lehmann.
9420 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
9422 * m4.h (_): Change argument from `x' to `Args'.
9424 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
9426 * m4.h: Rename Args() to _().
9427 * m4.h: Remove extern specifier from all function declarations.
9429 1994-04-22 Jim Avera <jima@netcom.com>
9431 * stackovf.c: New file implementing stack-overflow detection.
9432 * configure.in: Check for getrlimit, sigaction. If all of
9433 standard headers, getrlimit and sigaction, define USE_STACKOVF and
9434 substitute ${U}stackovf.o for STACKOVF.
9435 * acconfig.h: Declare USE_STACKOVF.
9436 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
9437 * m4.h: Declare setup_stackovf_trap().
9438 * m4.c: Call setup_stackovf_trap().
9439 * tests/stackovf_test.sh: New file.
9441 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
9443 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
9445 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
9447 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
9449 * m4.h: Remove definition of volatile, not used anymore.
9450 Reported by Jim Meyering and Joseph E. Sacco.
9452 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
9453 of `if ... else /* nothing */' for if macros.
9454 Reported by Jim Meyering.
9456 * builtin.c (m4_regexp): Reorganize the code for avoiding a
9457 warning from gcc about `repl' possibly used before defined.
9458 Reported by Jim Meyering.
9460 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
9461 Reported by Jim Meyering.
9463 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
9465 * m4.h: Move the conditional definition of volatile after the
9466 inclusion of system files, because they may define it first.
9468 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
9470 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
9471 get around a problem with Alpha make seeing a syntax error, there.
9472 Reported by Vern Paxson.
9474 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
9476 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
9477 Reported by Richard Stallman.
9479 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
9481 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
9482 instead of AC_HAVE_FUNCS.
9483 Reported by Noah Friedman.
9485 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
9487 * m4.c: Initialize show_help and show_version to zero.
9489 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
9490 Use them in exit() and usage() calls.
9492 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
9494 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
9495 syserr() macro. Delete errref, add reference_error and M4ERROR.
9496 * m4.c: Replace errref, which was returning an input reference
9497 string, with reference_error, which prints it on standard error.
9498 * builtin.c, output.c: Use errno as second parameter to error,
9499 instead of using syserr() with %s.
9500 * *.c: Use M4ERROR instead of error: no more errref() with %s.
9501 Doing so, the program name appears after the input reference
9502 instead of before, which eases M-x next-error processing.
9504 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
9506 * checks/get-them: Escape braces with backslashes in patterns,
9507 because HPUX-9.01 awk needs this.
9508 Reported by Jim Meyering.
9510 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
9512 * builtin.c: Declare "FILE *popen ();".
9514 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
9515 macros, replace error_message_prefix() declaration by errref()'s.
9516 Declare xrealloc, for use in errref().
9517 * m4.c: Delete error_message_prefix() function, add errref().
9518 * *.c: Use error() systematically in place of all error macros,
9519 now that error() flushes stdout first. Make needed adjustments.
9521 * m4.h: Remove const in sys_errlist[] declaration, it creates
9522 conflicts on SGI and Alpha.
9523 Reported by Kaveh R. Ghazi.
9525 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
9527 * m4.c: Include <getopt.h> instead of "getopt.h".
9529 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
9530 * acconfig.h: New, for documenting HAVE_EFGCVT.
9531 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
9532 use them wherever appropriate. Also use -I. for compilations.
9533 * lib/Makefile.in: Use -I.. for compilations.
9534 * *.c: Include <config.h> or "config.h".
9536 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
9537 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
9539 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
9541 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
9543 * input.c (input_init): Initialize quote and comment strings
9544 explicitely instead of calling set_quotes and set_comment: by
9545 doing so, we ensure we do not free uninitialized variables.
9547 * checks/check-them: Reverse arguments to both diff, so the
9548 expected is on the left and the obtained on the right.
9550 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
9551 macros. Delete declarations for m4error, warning, fatal and
9552 internal_error, add declaration for error_message_prefix.
9553 * m4.c: Delete m4error, warning, fatal and internal_error
9554 routines, add error_message_prefix routine.
9555 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
9556 warning with WARNING*, fatal with FATAL* and internal_error with
9557 INTERNAL_ERROR*.
9558 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
9559 this is not needed anymore.

9842 Reported by Pierre Gaumond.
9844 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
9846 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
9847 might well use CFLAGS is s/he needs it.
9849 * Makefile.in: Allow installation of info files from a separate
9850 build directory.
9851 Reported by Jason Merrill.
9852 Reported by David MacKenzie.
9853 Reported by Skip Montanaro.

9856 \f
9857 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
9859 * Release 1.0.3
9860 This is still a beta release for the future GNU m4 version 1.1.
9862 * lib/alloca.c: New, from elsewhere.
9863 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
9865 * m4.h: Do not define index/rindex if already defined. If
9866 FALSE/TRUE are already defined, do not redefine them, but merely
9867 define boolean typedef to int.
9869 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
9870 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
9871 because some C compilers do not like connectives with #ifdef.
9872 * m4.h: Define `volatile' only if __GNUC__, instead of once for
9873 __GNUC__ and once for __STDC__.
9874 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
9876 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
9877 Makefile dependencies. Without it, make keeps destroying and
9878 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
9880 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
9881 to diversion/DIVERSION, this was a spelling error.
9883 * m4.c: Declare version[], remove #include "version.h".
9884 * version.h: Deleted.
9885 * Makefile.in: Remove references to version.h.
9887 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
9888 production, by using a simpler and more robust algorithm. This
9889 solves the problem of synclines sometimes written in the middle of
9890 an output line. Delete sync_line() and output_lines variable.
9891 * m4.h: Remove sync_line prototype and output_lines declaration.
9892 * input.c (next_char), output.c (shipout_text): Remove references
9893 to output_lines.
9894 * input.c (push_file, pop_file): Merely put the value -1 in
9895 output_current_line instead of calling sync_line, for delaying a
9896 single `#line NUM FILE' before next output line. Do not test
9897 for sync_output, because this is unnecessary clutter.
9898 * output.c (make_divertion, insert_divertion): Idem.
9899 * input.c: Rename must_advance_line to start_of_input_line, for
9900 consistency.
9902 * debug.c (trace_header): Select a new debug line format, which
9903 better complies with GNU standards for formatting error messages.
9904 With option `-dfl', M-x next-error might be used on the output.
9905 * m4.c (vmesg): Adjust format of error output to GNU standards.
9906 * m4.texinfo: Adjust examples for `make check' to work.
9908 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
9909 case for enum debug_info constants, which were all lower case.
9911 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
9912 re_search_2.
9913 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
9914 collected patches. I tried a few times using newer regex.[ch], it
9915 mysteriously stopped aborting with this one. Insecure feeling...
9916 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
9918 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
9920 * m4.c: Change `--no-warnings' to `--silent'.
9921 Reported by David MacKenzie.
9923 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
9924 leave it off for now. See comment in m4.c for justification.
9925 Reported by David MacKenzie.
9927 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
9928 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
9930 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
9932 * Makefile.in: Ensure recursive cleaning is done before local
9933 cleaning for all clean goals.
9935 * builtin.c (ntoa): Ensure the value is always interpreted as a
9936 signed quantity, whatever the radix is.
9938 1992-11-18 Jim Meyering <meyering@idefix>
9940 * builtin.c, format.c, input.c: Split long lines.
9941 * m4.c: Use typedef macro_definition instead of struct
9942 macro_definition.
9943 * symtab.c: Use typedef symbol instead of struct symbol.
9945 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
9947 * *.[ch]: Remove all trailing whitespace, in code and comments.
9949 * configure.in: Find some awk.
9950 * Makefile.in: Add $(AWK) to MDEFINES.
9951 * checks/Makefile.in: Transmit $(AWK) to get_them.
9952 * checks/get_them: Use $AWK instead of gawk. Add a close in the
9953 awk script when switching files, because without this, mawk runs
9954 out of file descriptors.
9956 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
9958 * Makefile.in (realclean): Delete m4.info*.
9959 Reported by Jim Meyering.
9961 * Makefile.in: Adjust and link with checks/Makefile.
9962 * checks/Makefile.in: New.
9963 * configure.in: Output checks/Makefile.
9965 * checks/get_them: Have the dnl header of each test more
9966 recognizable by next-error, also use a better message.
9968 1992-11-16 Jim Meyering <meyering@idefix>
9970 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
9971 And use that only if __GNUC__ since we're using it's GCC-specific
9972 semantics that tell the compiler the associated function doesn't
9973 return.
9975 * builtin.c (substitute): Don't use character as an array index.
9976 (dumpdef_cmp): Make formal arguments `const void *' to avoid
9977 warnings with gcc -W -Wall on systems with qsort prototype.
9978 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
9979 from gcc -W -Wall.
9981 * eval.c (most functions): Add parentheses to assignments used
9982 as truth values go avoid warnings from gcc -Wall.
9984 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
9985 any functions that don't need external scope.
9987 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
9988 (many functions and arrays): Declare `const'.
9990 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
9992 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
9993 removing the declaration from m4.h. Also rename false to FALSE
9994 and true to TRUE.
9996 * lib/Makefile.in (Makefile): New goal.
9998 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
9999 so heavily loaded. It gets more easily overridable, calling make.
10000 Reported by Jim Meyering.
10002 * Makefile.in (dist): Get .fname from the current directory name,
10003 instead of from version.h. I need updating many files manually,
10004 when the version changes, version.h is just one of them.
10006 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
10008 * m4.h: Remove the tag `boolean' on the enum introducing typedef
10009 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
10010 Reported by Tom McConnell.
10012 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
10014 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
10015 39.cleardiv, which were describing missing or spurious newlines.
10016 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
10017 do not depend on machine word size, `/bin/false' implementation,
10018 or `wc' output format. `make check' is more dependable, now.
10020 * checks/check_them: Summarize the failed tests by listing their
10021 name, at end. If none, issue `All checks successful'. Output
10022 `Checking' instead of `Input file:'.
10024 * checks/get_them, checks/check_them: Reindented.
10026 * Makefile.in (dist): chmod a+r before making the tar file.
10028 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
10030 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
10032 * input.c (next_token): Reinitialize token_buttom just after using
10033 it as a watermark with obstack_free. Or else, a future token, big
10034 enough for triggering reallocation of the obstack chunk, could
10035 void the initialized value of token_buttom, later causing panic in
10036 obstack_free. Rename token_buttom to token_bottom everywhere.
10038 * m4.h: Before declaring errno, first include <errno.h> and
10039 ensure that it does not define errno.
10040 Reported by Richard Stallman.
10042 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
10044 * builtin.c: Define and use DECLARE macro for builtins.
10046 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
10047 argument, this is a common idiom for introducing long comments.
10049 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
10050 arguments. The last argument was silently ignored.
10052 * m4.c (cmd_error): Add a missing semicolon before va_end().
10054 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
10056 * Makefile.in: Now handle protoized sources. Define and use U.
10057 Compile and use ansi2knr with old compilers. Update DISTFILES.
10058 Add `aclocal.m4' to `configure' dependencies.
10059 * ansi2knr.c: New, from Ghostscript distribution.
10060 * configure.in: Define U through FP_PROTOTYPES for old compilers.
10061 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
10062 * aclocal.m4: New, provide FP_PROTOTYPES.
10063 * m4.h: Conditionnaly protoized through Args, save for varags.
10064 * builtin.c: Protoized. Then:
10065 Include <sys/types.h> if size_t is not defined, before "regex.h".
10066 (m4_ifelse): Fetch built-in name properly for diagnostic.
