1117 Reported by Elbert Pol.
1119 2008-04-14 Eric Blake <ebb9@byu.net>
1121 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1122 Improve arg_print to handle builtin tokens when printing to a
1123 known chain, rather than always flattening builtins. This allows
1124 m4wrap and $@ back-references to handle embedded builtin tokens.
1125 Memory impact: none.
1126 Speed impact: slight penalty, from more bookkeeping.
1127 * m4/m4module.h (m4_push_builtin): Add parameter.
1128 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
1129 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...

1135 builtin to a growing symbol chain.
1136 * m4/symtab.c (m4__symbol_value_print): Alter signature.
1137 (m4_symbol_print, dump_symbol_CB): Adjust callers.
1138 * m4/input.c (builtin_peek, builtin_read, builtin_unget)
1139 (builtin_print, builtin_funcs): Delete, handled via composite
1141 (struct m4_input_block): Delete u.builtin member.
1142 (init_builtin_token): Only use composite block.

1147 (composite_print, m4_print_token): Adjust callers.
1148 * m4/macro.c (m4_wrap_args, collect_arguments): Allow builtin
1150 (m4__arg_print): Alter signature.
1151 (trace_prepre, trace_pre, m4_arg_text, m4_arg_equal): Adjust
1153 * modules/m4.c (m4wrap): Allow builtin tokens.

1159 Stage 21a: Optimize checks for end of input.
1160 Create a new polymorphic input block type, which always fails with

1169 (m4_input_exit): Use placeholder to guarantee non-NULL isp and
1171 (next_char): Rename retry to allow_unget, and change sense for
1172 easier manipulation. All callers changed.
1174 Improve OS/2 detection.
1175 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
1176 are defined, not just the first. The testsuite ensures that
1177 exactly one gets defined.
1178 * m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter
1179 what other pre-defined macros it has.

1198 Be namespace clean for M4 version; fixes 2008-04-08 regression.
1199 * configure.ac (version): Rename...
1200 (M4_VERSION): ...to this, since using 'version' broke po.m4.
1202 2008-04-09 Eric Blake <ebb9@byu.net>
1204 Mention 1.4.11 release.
1205 * doc/m4.texinfo (History, Defn, Ifdef, Ifelse, M4wrap)

1211 2008-04-08 Eric Blake <ebb9@byu.net>
1213 Overhaul inter-version releases to work with git.
1214 * configure.ac (version): New variable, which has nicer version
1215 contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
1216 (TIMESTAMP): Delete, since CVS id expansion died with transition
1218 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
1219 * build-aux/mkstamp: Delete, no longer used.
1220 * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up
1221 rebuilds when timestamps don't matter.
1222 (MKSTAMP): Delete, no longer used.
1223 (EXTRA_DIST): No longer worry about mkstamp.
1224 (.version): New rule and distributed file.
1225 (doc/m4.1, tests/package.m4): Depend on .version, not
1226 configure.ac, for timestamp.
1227 * ltdl/m4/gnulib-cache.m4: Import git-version-gen module.
1228 * modules/gnu.c (__m4_version__): TIMESTAMP no longer exists.

1238 2008-03-18 Eric Blake <ebb9@byu.net>
1240 Stage 20b: make m4wrap obey POSIX fifo ordering.
1241 Improve input engine to support location changes within symbol
1242 chains, then convert m4wrap to always build symbol chain.
1243 Memory impact: none.
1244 Speed impact: slight penalty, from more m4wrap bookkeeping.
1245 * m4/m4module.h (m4_wrap_args): Add prototype.

1257 * tests/builtins.at (wrap): Likewise.
1258 * NEWS: Document this change.
1260 2008-03-17 Eric Blake <ebb9@byu.net>
1262 Stage 20a: reduce unget's in input engine.
1263 Now that out-of-range input placeholders like CHAR_BUILTIN are
1264 consumed outside of next_char, next_token should always consume
1265 rather than peek at the first character. Fewer peeks results in
1266 less ungetc overhead.
1267 Memory impact: none.
1268 Speed impact: noticeable improvement, from fewer function calls.
1269 * m4/input.c (struct input_funcs): Alter read_func prototype.
1270 (next_char, file_read, buildin_read, string_read, composite_read):
1271 Add allow_argv parameter.

1290 (M4wrap): ...here, to match improved example.
1292 2008-03-13 Eric Blake <ebb9@byu.net>
1294 Stage 19c: allow builtin tokens in more macros.
1295 Allow builtin tokens inside symbol chains, although for now, they
1296 are not allowed inside comments or quotes. Enable builtin token
1297 handling in more macros, if only to consistently diagnose invalid
1299 Memory impact: none.
1300 Speed impact: slight impact, due to more bookkeeping.
1301 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New

1318 (arg_symbol): Add parameter, and allow NULL level.
1319 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
1320 (m4_arg_text): Ensure all builtins have been flattened.

1327 (Debuglen): Likewise, and remove xfail.
1328 * NEWS: Mention the change.
1330 Stage 19b: invert sense of bit for handling builtin tokens.
1331 Pass builtin tokens by default, rather than as the exception, so
1332 that the logic can consistently refer to flattening arguments.
1333 Memory impact: none.
1335 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1336 (M4_BUILTIN_GROKS_MACRO): Rename...

1348 * m4/module.c (m4__module_open): Require arguments if flattening

1363 are stringized without preprocessor expansion.
1364 * doc/m4.texinfo (Defn): Update comments to match reality.
1365 (Debuglen): Update test now that user macros pass builtin tokens.
1367 Stage 19a: sort and cache builtins loaded by a module.
1368 Rather than repeatedly using dlsym to browse the builtin table,
1369 copy off the table at module load time. Then, the input engine
1370 merely refers to the copy instead of duplicating information.
1371 Memory impact: slight penalty, due to more memory per module, but
1372 offset by less memory in input engine.
1373 Speed impact: slight improvement, due to faster builtin lookups.
1374 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use

1439 Stage 18: try harder to reuse argv in recursion.
1440 When pushing arguments that contain an existing $@ ref, reuse the
1441 ref rather than creating another layer of wrappers.
1442 Memory impact: noticeable improvement, due to better $@ reuse.
1443 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1444 reduction in unboxed recursion.
1445 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1446 (m4_push_args): Let make_argv_ref take care of pending data.
1447 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1448 performance capability.

1452 2008-02-22 Eric Blake <ebb9@byu.net>
1455 * NEWS: Document change to __gnu__ on 2008-02-11.
1457 Stage 17: pass argv through quoted strings.
1458 Allow the concatenation of $@ references with other text input
1459 inside quoted contexts, which requires distinguishing between a
1460 wrapper around many arguments vs. a reference serving as part of a
1461 single argument. Also optimize based on whether argv contains
1462 builtin tokens that might need flattening to the empty string.
1463 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1464 reduction from total reuse of $@ references.
1465 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1466 reduction in boxed recursion.
1467 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.

1486 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1487 undo argument collection optimisation for strings, so that
1488 m4_print_token doesn't abort when it otherwise receives an
1489 unprintable M4_SYMBOL_VOID type token.
1491 2008-02-20 Eric Blake <ebb9@byu.net>
1493 Stage 16: cache quotes and improve m4_arg_print.
1494 Cache rather than always copying quotes when pushing $@ refs; in
1495 particular, reconstruct single-byte quotes on the fly. Allow NUL
1496 through m4wrap. Improve sharing of code that prints arguments.
1497 Memory impact: slight improvement, due to cached quotes.
1498 Speed impact: slight improvement, due to less copying.
1499 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1500 (m4_arg_print): Adjust prototypes.

1512 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1513 * m4/utility.c (m4_dump_args): Delete; callers should use
1514 m4_arg_print instead.
1515 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1516 implementation, and allow embedded NUL.
1517 (m4_print_token, pop_input, composite_print, composite_peek):
1518 (composite_read, append_quote_token): Adjust all callers.
1519 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
1521 (m4_arg_print): Add parameters.
1522 (trace_pre): Rewrite in terms of m4_arg_print.
1523 * modules/m4.c (errprint): Likewise.

1532 Reported by Ralf Wildenhues.
1534 * doc/m4.texinfo (Debuglen, Changesyntax): Fix typos.
1536 2008-02-19 Eric Blake <ebb9@byu.net>
1538 Clean up example on filtering defined symbols.
1539 * doc/m4.texinfo (Foreach, Improved foreach): Document another
1540 shortcoming in foreach.m4, and improve filter example by using

1545 2008-02-18 Eric Blake <ebb9@byu.net>
1547 Avoid some magic numbers.
1548 * m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)
1549 (CHAR_RETRY): Define in terms of UCHAR_MAX.
1550 * m4/syntax.c (m4_syntax_create, set_syntax_set)
1551 (reset_syntax_set, check_is_single_quotes)
1552 (check_is_single_comments, check_is_macro_escaped)

1567 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1568 (Improved foreach): Adjust dump from file.
1570 Stage 15: return argv refs back to collect_arguments.
1571 Collect an entire $@ reference at once rather than one argument at
1572 a time, outside of quotes (but inside quotes, $@ is still
1573 flattened for now). The skip_last field allows concatenation of
1574 $@ with other text when collecting arguments.
1575 Memory impact: noticeable improvement, due to better reuse of $@.
1576 Speed impact: noticeable improvement, due to less parsing.
1577 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1578 (enum m4__token_type): Add M4_TOKEN_ARGV.
1579 (struct m4__symbol_chain): Add skip_last member to argv link.

1677 Stage 14b: allow pushing argv references.
1678 Push a $@ reference to the input engine in one go, rather than
1679 pushing each element. For now, argument collection still gets one
1680 argument of a $@ at a time; but the penalties of this patch make
1681 it easier to manage $@ efficiently in future patches.
1682 Memory impact: noticeable penalty, due to larger struct and O(n)
1683 to O(n^2) on unboxed recursion.

1696 (arg_symbol, make_argv_ref, m4__push_arg_quote): ...to these new
1697 helper functions, to add parameters.
1698 (m4_push_args): Adjust caller.
1699 * m4/symtab.c (m4_symbol_value_print): Likewise.
1701 Stage 14a: allow printing argv references.
1702 Refactor symbol-value printing code for better sharing, and to
1703 allow printing a contiguous text representation of a $@ ref.
1704 Memory impact: none.
1706 * m4/m4module.h (m4_arg_print): New prototype.
1707 (m4_symbol_value_print): Alter prototype.

1712 to avoid infinite recursion in next patch.
1713 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
1714 (m4_arg_print): New function.
1715 * m4/symtab.c (m4_symbol_value_print): Update signature.
1716 (m4_symbol_print): Update caller.
1717 * m4/output.c (m4_shipout_string_trunc): Update comments.
1718 * m4/syntax.c (set_quote_age): Require comma as argument separator
1719 when dealing with $@ as a unit.
1720 * tests/builtins.at (ifelse): Augment test.
1721 * doc/m4.texinfo (Changesyntax): Document changesyntax deficiency.

1768 Support pushing composite tokens, allowing back-references to be
1769 reused through multiple macro expansions. Add hueristic that
1770 avoids creating new reference when pushing existing references.

1901 * m4/macro.c (expand_argument): Collect composite arguments.
1902 (collect_arguments): Update new field.
1903 (expand_macro): Reduce ref-count of back-references after use.
1904 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
1906 (m4_is_arg_text): Also recognize composite symbols as text.
1907 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
1908 (m4_arg_equal): Compare composite symbols.
1909 (m4_push_arg, m4_push_args): Handle composite symbols.
1910 (m4_arg_symbol): Relax assertion.
1911 (process_macro): Use single-argument references.
1912 * m4/output.c (m4_shipout_string_trunc): Update comment.
1913 * tests/macros.at (Rescanning macros): Augment test.
1915 2008-01-16 Eric Blake <ebb9@byu.net>
1917 Stage 10: avoid extra copying of strings and comments.
1918 When collecting tokens that are immune to further expansion, avoid
1919 copying data from one obstack to another by outputting it into the
1920 destination obstack to begin with. Also reduce copying done in
1922 Memory impact: slight improvement, due to better obstack usage.
1923 Speed impact: noticeable improvement, due less data copying.
1924 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
1926 * m4/m4private.h (m4__token_type): Adjust prototype.
1927 * m4/input.c (m4__next_token): Support new parameter.
1928 * m4/macro.c (m4_macro_expand_input, expand_token)
1929 (expand_argument, collect_arguments): Adjust callers.
1930 * modules/m4.c (ntoa): Tighten buffer size.
1931 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
1932 * modules/format.c (arg_int, arg_long, arg_double): New helper
1933 functions, to detect overflow or unparsed characters.
1934 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
1935 missing or excess arguments.
1936 (format): Likewise, and also output directly into obstack if there
1938 * doc/m4.texinfo (History): Update for new year.
1939 (Format): Test for new warnings.
1941 2008-01-15 Eric Blake <ebb9@byu.net>
1943 * TODO: Update with some newer URLs.
1945 Verify linear `index'.
1946 * tests/builtins.at (index): New test.
1947 (translit): Make test take longer, to make quadratic algorithms
1950 2007-12-20 Eric Blake <ebb9@byu.net>
1952 Stage 9: share rather than copy single-arg refs.
1953 Use hooks of previous patch to create back-references to arguments
1954 in the input engine, and inline short text rather than always
1955 creating a FIFO link. Also start testing embedded NUL behavior.
1956 Until the argument collection engine also shares references, the
1957 memory usage increases.
1958 Memory impact: noticeable penalty, due to longer life of argv
1959 changing O(n) to O(n^2) on boxed recursion.
1960 Speed impact: slight improvement, due less data copying.
1961 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
1962 * m4/m4module.h (m4_arg_scratch): New prototype.
1963 * m4/m4private.h (m4__push_symbol): Add parameter.
1964 (m4_arg_scratch): Add fast accessor.
1965 (struct m4): Add expansion_level member, taken...
1966 * m4/macro.c (expansion_level): ...from here. Adjust all users.
1967 (expand_argument): Minor cleanup.
1968 (expand_macro): Track scratch space per macro call.
1969 (m4_arg_scratch): New function.
1970 (m4_make_argv_ref): Call new function.
1971 (m4_push_arg): Push reference to $0.
1972 (m4_push_args): Rework separator usage, since separators will
1974 (process_macro): Allow embedded NUL.
1975 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
1976 (m4__push_symbol): Add parameter. Inline short strings, and save
1977 references through rescanning.
1978 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
1979 * modules/m4.c (errprint, index): Handle NUL transparently.
1980 (dumpdef, translit): Use scratch space, rather than expansion
1982 * modules/gnu.c (renamesyms, m4symbols): Likewise.
1983 * tests/others.at (nul character): New test.
1984 (iso8859): Quote absolute file name, remove XFAIL.
1985 * tests/iso8859.m4: Avoid raw NUL in output.
1986 * tests/null.m4: New file.
1987 * tests/null.out: Likewise.
1988 * tests/null.err: Likewise.
1989 * Makefile.am (OTHER_FILES): Distribute new files.
1990 * .gitattributes: Treat new files as text.
1992 2007-12-17 Eric Blake <ebb9@byu.net>
1994 Stage 8: extend life of references into argv.
1995 Add hooks to lengthen the lifetime of arguments reused in a macro
1996 expansion, rather than always discarding arguments at the end of
1997 expand_macro. Rework the expand_macro obstacks to handle longer
1998 lifetimes. For now, the hooks remain unused.
1999 Memory impact: slight penalty, due to larger structs.
2000 Speed impact: slight penalty, due to more bookkeeping.
2001 * m4/system_.h (obstack_regrow): Delete.
2002 * m4/m4private.h (struct m4_symbol_chain): Add level field.
2003 (m4__push_symbol): Adjust prototype.
2004 (m4__adjust_refcount): New prototype.
2005 (DEBUG_MACRO) [DEBUG]: New debug control.
2006 (struct m4__macro_arg_stacks): New structure.
2007 (struct m4): Add arg_stacks, stacks_count fields.
2008 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2009 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2010 context->arg_stacks.
2011 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2012 conditional on M4_DEBUG_MACRO envvar.
2013 (collect_arguments): Adjust signature.
2014 (expand_macro): Rework obstack handling.
2015 (m4__adjust_refcount, arg_mark): New functions.

2020 * m4/input.c (make_text_link): Use new field.
2021 (m4__push_symbol, file_clean): Update signature.
2022 (composite_read): Bump refcount when done with reference.
2023 (composite_clean): New function.
2024 (pop_input): Adjust caller.
2025 * m4/debug.c (m4_debug_message): Make assertion match comment.
2026 * modules/gnu.c (builtin, indir): Adjust callers.
2027 * tests/builtins.at (ifelse): New test.
2028 (exp): Move and rename...
2029 * tests/others.at (countdown): ...to this.
2030 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2033 2007-12-13 Eric Blake <ebb9@byu.net>
2036 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2041 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2043 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2045 Reported by Giovanni Toffetti.
2047 2007-12-11 Eric Blake <ebb9@byu.net>
2049 Stage 7: use chained input support in input parser.
2050 Allow the LIFO input engine to rescan a macro expansion composed
2051 of smaller chunks of FIFO data, rather than the old approach of a
2052 monolithic string. For now, all chunks are still copied.
2053 Memory impact: slight penalty, due to FIFO chain overhead.
2054 Speed impact: slight penalty, due to extra bookkeeping.
2055 * m4/m4private.h (m4__push_symbol): New prototype.
2056 (struct m4_symbol_chain): Add const-safety.
2057 * m4/symtab.c (m4_symbol_value_print): Simplify.
2058 (dump_symbol_CB): Update caller.
2059 * m4/input.c (struct m4_input_block): Alter u_c member, first
2060 introduced 2006-10-25, but unused until now.
2061 (composite_peek, composite_read, composite_unget)
2062 (composite_print, init_builtin_token): Rewrite accordingly.
2063 (m4_push_wrapup): No longer need trailing NUL.
2064 (m4__push_symbol, make_text_link): New functions.
2065 (m4_push_string_finish): Use them.
2066 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2067 (expand_macro): Simplify logic of nesting_limit.
2068 * src/main.c (main): Likewise.
2069 * doc/m4.texinfo (Dumpdef): Augment test.
2071 2007-12-08 Eric Blake <ebb9@byu.net>
2073 Stage 6: convert builtins to push arg at a time.
2074 Add new methods to factor all builtins whose expansion includes an
2075 argument, making back-reference creation easier in future patches.
2076 Factor out length-limited printing to obstacks, and use -1 rather
2077 than 0 for unlimited length.
2078 Memory impact: none.
2079 Speed impact: slight improvement, due to better code sharing.
2080 * m4/m4module.h (m4_shipout_text): Rename...
2081 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2082 that does not worry about sync lines.
2083 (m4_shipout_string_trunc): New prototype.
2084 * m4/output.c (m4_shipout_text): Rename...
2085 (m4_divert_text): ...to this.
2086 (m4_shipout_string): Move guts...
2087 (m4_shipout_string_trunc): ...to this new function.
2088 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2089 (expand_token, process_macro): Update callers.
2090 * m4/input.c (string_print): Likewise.
2091 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2093 * modules/gnu.c (patsubst): Likewise.
2094 (debuglen): Use SIZE_MAX for unlimited debug length.
2095 * src/main.c (main): Likewise.
2096 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2099 2007-12-07 Eric Blake <ebb9@byu.net>
2101 Minor security fix: Quote output of mkstemp.
2102 * modules/m4.c (m4_make_temp): Produce quoted output.
2103 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2106 Stage 5: add notion of quote age.
2107 Cache the quoting rules that were in effect when a string was
2108 parsed, to avoid reparsing that string if no changequote or other
2109 quote age change took place in the meantime. A quote_age of 0 is
2110 always safe, but does not benefit from caching.
2111 Memory impact: slight improvement, due to smaller struct in input
2113 Speed impact: slight penalty, due to more bookkeeping.
2114 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
2115 (m4_set_symbol_value_text): Adjust prototype.
2116 (m4_has_syntax): Factor out the unsigned char cast.
2117 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
2119 (m4__quote_age, m4__safe_quotes): New accessor macros, no need for
2120 functions at this point.

2127 (m4_symbol_value_copy): Adjust callers.
2128 * m4/macro.c (expand_token): Add parameter, and track quote age.
2129 (expand_argument, collect_arguments): Track quote age.
2130 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
2131 (m4_macro_expand_input): Update callers.
2132 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.

2148 * tests/builtins.at (changequote, defn): New tests.
2149 * examples/wrapfifo.m4: New file.
2150 * examples/wraplifo.m4: New file.
2151 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
2153 2007-12-04 Eric Blake <ebb9@byu.net>
2155 Fix builds with OpenBSD make.
2156 * Makefile.am (HELP2MAN): New macro.
2157 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
2159 * README: Update copyright.
2160 * HACKING: Mention help2man and makeinfo dependencies.
2162 2007-11-29 Eric Blake <ebb9@byu.net>
2164 Stage 4: route indir, builtin through ref; make argv opaque.
2165 Finish making struct opaque to all but the input engine, by
2166 reworking obstack usage in expand_macro to better support creation
2167 of a $@ reference. Canonicalize the empty argument, to allow
2168 pointer comparison optimizations.
2169 Memory impact: slight penalty, due to larger struct.
2170 Speed impact: slight improvement, due to fewer function calls.
2171 * m4/system_.h (obstack_regrow): Fix precedence.
2172 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2174 (struct m4_macro_args): Move...
2175 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2176 to modules. Add has_ref member.
2177 (bool_bitfield): New helper typedef.
2178 (struct m4_symbol_chain): Add flatten and len members.
2179 * m4/macro.c (empty_symbol): New placeholder, for optimizing

2183 (trace_pre, trace_post): Remove redundant parameter.
2184 (expand_macro): Alter handling of obstacks.
2185 (m4_arg_symbol): Account for wrapped argv.
2186 (m4_arg_equal, m4_arg_empty, m4_make_argv_ref): New methods.
2187 (m4_arg_text, m4_arg_len, m4_arg_func): Use new methods.
2188 * modules/m4.c (ifelse, syscmd): Likewise.
2189 * modules/evalparse.c (m4_evaluate): Likewise.
2190 (undefine, popdef, m4_dump_symbols): Optimize.
2191 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
2193 (changesyntax, regexp): Optimize.
2194 * m4/output.c (diversion_storage): Use typedef.
2196 Stage 3b: cache length, rather than computing it, in modules.
2197 Use cached token length in builtins and output engine.
2198 Memory impact: none.
2199 Speed impact: noticeable improvement, due to fewer function calls.
2200 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2202 * m4/output.c (m4_shipout_string): Change semantics of len param.
2203 (m4_shipout_int): Use cached length.
2204 * m4/input.c (m4_push_string_finish): Likewise.

2211 * m4/symtab.c (m4_symbol_value_print): Likewise.
2212 * modules/gnu.c (__file__, __program__, builtin, indir)
2213 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
2214 renamesyms, patsubst, regexp, regexp_compile): Likewise.
2215 * modules/load.c (m4modules): Likewise.

2225 * tests/others.at (iso8859): XFAIL this test, now that
2226 length-based handling allows NUL through part but not all of M4.
2228 2007-11-28 Eric Blake <ebb9@byu.net>
2230 Stage 3a: cache length, rather than computing it, in libm4.
2231 Cache the length of a token in the input engine and symbol table,
2232 to avoid repeating lots of strlen calls. Additionally, by using
2233 obstack length rather than strlen, the input engine can now
2234 support embedded NUL.
2235 Memory impact: slight penalty, due to larger struct.
2236 Speed impact: slight improvement, due to fewer function calls.
2237 * m4/m4module.h (struct m4_macro_args): Cache length.
2238 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.

2260 Adjust implementation.
2262 2007-11-27 Eric Blake <ebb9@byu.net>
2264 Stage 2: use accessors, not direct reference, into argv.
2265 Outside of macro.c, use accessor methods rather than direct access
2266 into the argv struct.
2267 Memory impact: none.
2268 Speed impact: slight penalty, due to increased function calls.
2269 * m4/m4private.h (m4_arg_argc): New fast accessor.
2270 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)

2273 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
2274 (m4_macro_call): Make argc unsigned.
2275 (M4ARG): Use new accessors.

2288 (expand_macro, trace_pre, trace_post, m4_macro_call): Update argc
2291 2007-11-24 Eric Blake <ebb9@byu.net>
2293 Stage 1: convert m4_symbol_value** into new object.
2294 Pass a variable-size wrapper structure instead of an array to
2295 builtins, so that subsequent optimizations in the structure need
2296 not impact every builtin client.
2297 Memory impact: slight penalty, since struct is larger than array.
2298 Speed impact: slight penalty, due to increased bookkeeping.
2299 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
2300 * m4/m4module.h (m4_macro_args): New type, will be opaque to
2302 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)

2376 Note: Patches titled Stage 0 through N form a series of patches
2377 which decreases the algorithmic complexity of tail recursion in
2378 macro expansions from O(n^2) to O(n) in both time and memory, then
2379 performs cleanups, such as handling of embedded NUL, made easier
2380 by the code refactoring.

5182 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
5183 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
5184 atlocal takes care of it instead.
5185 (check-local, installcheck-local, clean-local): Inline absolute
5186 path to testsuite here, rather than relative path to testsuite
5189 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5191 * m4/m4private.h (DELETE): Cast away const here...

5204 2006-06-16 Eric Blake <ebb9@byu.net>
5206 Follow recommendations from autoconf manual for autotest.
5207 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
5208 turn it into an absolute path until autotest provides an option
5209 that allows us to avoid changing directories. Properly quote
5211 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
5212 (check-recursive): Delete unused target.
5213 ($(TESTSUITE)): Atomically update testsuite.
5214 (CD_TESTDIR): Simplify.

5238 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
5240 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
5242 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
5243 const mpq_t is not assignable from plain mpq_t. Avoid
5244 type-punning warnings caused trying to mix these types.
5245 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5246 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

5260 and Eric Blake <ebb9@byu.net>
5262 Allow `make dist' to work again.

5264 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
5265 (cvs-dist): Fix typo.
5266 * NEWS: Match current version number.

5270 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
5273 * bootstrap: Do not run libtoolize manually, this is done
5274 correctly by autoreconf. Invoke autoreconf with --no-recursive
5275 to avoid unnecessary rerunning of autotools for libltdl.
5277 2006-06-13 Eric Blake <ebb9@byu.net>
5281 2006-06-12 Eric Blake <ebb9@byu.net>
5283 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't

5286 * m4/input.c (m4__next_token): Avoid bzero.
5287 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
5288 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
5289 than distributing outdated helptoman.pl.
5290 * doc/helptoman.pl: Delete.
5292 2006-06-10 Eric Blake <ebb9@byu.net>
5294 * README (Patches): Document the current dependence on CVS
5295 builds of autotools.

5297 * configure.ac: Use consistent quoting throughout.
5298 (AC_PREREQ): Bump to 2.59d.
5299 (AC_INIT): Package name begins with uppercase.
5300 (AC_ARG_WITH): Use AS_HELP_STRING.
5301 (AM_INIT_AUTOMAKE): Enable gnits mode.
5302 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
5303 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
5304 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
5305 done by gnulib or automake, or which autoconf has declared

5318 * THANKS: Likewise. Change encoding to UTF-8.
5319 * BACKLOG: Delete. This file is too old and unmaintained to be
5321 * ChangeLog: Change encoding to UTF-8.
5323 Avoid compiler warnings.
5324 * m4/macro.c (trace_format): Don't mark this as a printf format,
5325 since we don't accept the same set of modifiers as printf. It
5326 would be nice if gcc let us specify a custom format archetype.
5327 * src/main.c (main): Cast away const.
5329 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
5330 Eric Blake <ebb9@byu.net>

5379 2005-12-05 Gary V. Vaughan <gary@gnu.org>
5381 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
5382 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5383 Reported by Eric Blake <ebb9@byu.net>
5385 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5387 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5388 http caching as -C is no longer supported by wget 1.10.x.
5389 Reported by Eric Blake <ebb9@byu.net>
5391 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5393 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5395 (iface_id): ...an lt_dlinterface_id type.
5396 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5397 throughout, instead of calling obsolete lt_dlhandle_find directly.
5398 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
5399 throughout, instead of calling obsolete lt_dlhandle_next.
5400 * m4/m4private.h (m4__module_find): Declare it.
5401 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
5402 Use m4__module_next instead of obsolete lt_dlhandle_next.

5410 these files under source control anymore.
5411 Suggested by Eric Blake <ebb9@byu.net>
5413 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5415 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5416 file escaped the address updates on 2005-05-01.
5418 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5420 * bootstrap: Allow user overriding of gnulib-tool location, and
5421 correctly determine module source directories whether gnulib-tool
5422 is given as a relative or absolute path, or is found by searching
5424 Reported by Eric Blake <ebb9@byu.net>

5440 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5442 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5443 level symbol rename.
5444 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5445 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5446 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5448 (erenamesyms, renamesyms): ...builtins that use these to implement
5449 macro renaming by regular expression.
5450 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5451 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5452 to stop the new generated tests from choking.
5454 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5456 Since most of the build is handled from a single Makefile.am now,
5457 we can teach make about the dependencies between the m4 binary and
5458 the preopened modules it is built against:
5460 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5462 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5463 of the preopened modules have changed.
5465 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5467 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5468 have a native implementation.
5470 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5472 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5473 handled already by gnu/exit.h.
5475 * configure.ac (gl_MODULES): Add assert to support a
5476 --disable-assert configure time option for NDEBUG setting.
5478 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5479 * bootstrap (src_modules): Add version-etc-fsf.
5480 * src/main.c (version_etc_copyright): Removed.
5482 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5484 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5486 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5488 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5489 on Windows, so that the frozen file reader will work.

5492 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
5494 Forward port of a patch that allowed m4-1.4.2 to compile on
5497 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5499 * src/m4.h: And include them as appropriate.
5500 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5501 m4.h will include the correct file.
5503 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5505 * m4/m4private.h: Make errno visible for the sources patched
5508 2005-05-04 Paul Eggert <eggert@twinsun.com>
5510 * src/main.c (print_program_name_CB): Preserve errno, since
5511 M4ERROR relies on this.
5512 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5513 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5514 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5517 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5518 value simply because fread returns zero. This fixes a
5519 portability bug reported by Marion Hakanson in
5520 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
5522 2005-05-04 Santiago Vila <sanvila@debian.org>

5529 * m4/output.c (m4_insert_file): Do not mix buffered and
5530 unbuffered I/O, as this breaks on the Hurd.
5532 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5534 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5535 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5536 and libtoolize does a better job of ltdl importing now too, so
5537 take advantage of that while updating the tree:
5539 * acm4, config: Moved from here...
5540 * ltdl/m4, ltdl/config: ...to here.
5541 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
5542 src/Makefile.am, tests/Makefile.am: Removed...
5543 * Makefile.am: ...and migrated to here, with adjustments to
5544 compensate for relative path differences.
5545 * commit: Adjust relative paths.
5546 * configure.ac: Adjust relative paths.
5547 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5549 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5550 the meanwhile, CVS HEAD libtool is needed.
5551 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5552 stricly new enough, we also need a patch.
5553 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5554 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5555 (gl_MODULES): Don't list getopt and version-etc, as they don't
5557 * bootstrap: After running gnulib-tool to import the listed
5558 modules, fetch getopt and version-etc into src manually.
5559 (ltdldir): Change to ltdl.
5560 * src/main.c: Adjust for changes in version-etc API.
5561 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5562 but works when the getopt module isn't to be included in the lib.
5563 * README: Add note about patching autoconf and automake to

5569 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
5570 empty file rather than to a nonexistent file. This closes a
5571 common security hole.
5572 * modules/m4.c (m4_maketemp): Implement the above, by using
5573 mkstemp rather than mktemp.

5618 Protect definitions from macro expansion under -DNDEBUG by
5619 parenthesising the expanded function names.

5622 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5623 (m4_is_syntax_macro_escaped): Similarly protect function
5624 definitions from macro expansion under -DNDEBUG by #undefing the
5625 matching macro names before each definition. Also, move all the
5626 function definitions to the end of the file so that any
5627 invocations in the rest of the file pick up the fast macro
5629 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)

5641 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5643 * src/main.c: Include gnulib files from the correct directory.
5645 * gnulib/*: Don't store any of the gnulib files in arch, as they
5646 generate spurious changes.
5647 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5648 gnulib macros now share our macro directory.
5649 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5650 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5651 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5652 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5653 the gettext macros from autopoint that overwrite the gnulib-tool
5654 imported versions. Import sources and Makefile.am into the `gnu'
5655 directory. Changed all callers.
5656 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5657 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5658 for imported modules.
5659 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5660 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5661 hardcoding the gnulib macros they wrap.
5663 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5665 Latest CVS libtool can preload modules in libraries, including
5666 its own module loaders! Tweak m4 so that it doesn't try to treat
5667 libltdl's module loaders as m4 modules when freezing and on exit:
5669 * gnulib/acm4/*.m4: Don't store these files in arch since they
5670 generate spurious changes.
5671 * bootstrap: Simplify initial libtoolize call, since CVS
5672 libtoolize is smarter these days.
5673 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5675 * m4/module.h (m4__module_exit): Missing declaration.
5676 * m4/m4private.h (m4__module_next): New function declaration.
5677 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5678 encapsulation. Changed all callers.
5679 (m4__module_interface): New function to verify m4 loadable module
5681 (m4__module_init): Register the interface validator.
5682 (m4__module_exit): Only close my own modules.
5683 * modules/m4.c (unistd.h): Provide missing declaration.
5684 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5685 (m4_expand_ranges): More missing declarations.
5686 * modules/modtest.c (export_test): Ditto.
5687 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5688 * src/main.c (main): Bump copyright year.
5689 * tests/modules.at: Fix sed syntax error.
5692 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5694 Tweaking to enable compilation with latest CVS libtool and
5695 libltdl. We can't just dump the library files directly into the
5696 m4 directory anymore now that libltdl is built from pieces itself:
5698 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5699 set up libltdl subdirectory.
5700 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5701 gnulib subdirectory's config.
5702 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5703 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5705 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5706 configure.ac, so use AC_WITH_LTDL instead.
5707 * Makefile.am (SUBDIRS): Add libltdl.
5708 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5710 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
5711 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
5712 (libm4_la_LIBADD): Add LIBLTDL.
5713 * m4/ltdl.c, m4/ltdl.h: Removed.
5714 * m4/m4module.h: Include canonical ltdl.h.
5717 2004-06-14 Gary V. Vaughan <gary@gnu.org>
5719 * gnulib/import: Now updates makefile fragments, and configure.ac.
5720 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
5721 * gnulib/m4/Makefile.am: include it.
5722 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
5723 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
5724 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
5725 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
5726 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
5727 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
5728 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
5729 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
5730 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
5731 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
5732 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
5733 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5734 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5736 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5738 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5739 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
5740 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
5741 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5742 Updated source files from latest gnulib.
5744 2004-02-29 Gary V. Vaughan <gary@gnu.org>
5746 * config/mailnotify: New file for mailing commit notifications,
5747 imported from cvs-utils.
5748 * commit: Updated from cvs-utils and tweaked for m4.
5750 2003-12-01 Gary V. Vaughan <gary@gnu.org>
5752 * config/mkstamp: Updated from CVS libtool.
5753 * configure.ac: Generate a gnu coding standards compliant version
5754 number, and use it for the banner.
5755 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5756 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5757 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5758 contain the previous version number.
5759 * src/main.c: Make --version output conform to the GNU standard.
5761 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5762 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5763 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5764 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5765 time_la_SOURCES): ...so that these are defaulted correctly, and
5766 can be removed from this file.
5767 (AM_LDFLAGS): Add -module...
5768 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5769 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5770 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5771 the individual settings can be removed.
5772 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5773 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5774 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5775 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5776 time_la_LIBADD): ...so that these are picked up as a deplib of
5777 libm4 and don't need to be set explicitly.
5779 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5781 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5782 from the standard build. It is too fragile.
5784 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5785 CVS libtool after merging m4 changes across to libtool.
5787 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5788 * m4/path.c (search_path_add): Ditto.
5790 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5792 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5793 libtool tags we don't use in configure. This reduces the size
5794 of the script from over 1Mb to under 700Kb.
5796 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5798 The import script was not written properly, and the last gnulib
5799 import was incomplete. Fixed that problem, and reimport our
5800 gnulib dependencies, which picks up the address calculation
5801 overflow checks described by Paul below. Also tweak the clients
5802 of the gnulib xalloc module not to use deprecated macros:
5804 * gnulib/import: Recurse through module dependencies rather than
5805 naively descending only one level.
5806 * configure.ac: Add calls to gnulib's strnlen and extension module
5808 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5810 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5811 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5812 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
5813 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
5815 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
5816 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
5817 place of `xcalloc (1, S)'.
5818 * m4/m4.c (m4_create): Likewise.
5819 * m4/m4private.h (m4_symbol_value_create): Likewise.
5820 * m4/symtab.c (symtab_fetch): Likewise.
5821 * m4/syntax.c (m4_syntax_create): Likewise.
5822 * src/freeze.c (reload_frozen_state): Likewise.
5823 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
5825 * m4/symtab.c (m4_symtab_create): Likewise.
5827 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5829 * tests/module.at: Comment typo.
5831 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5833 * tests/modules.at (modules: importing): Apply some lateral
5834 thinking, and use AT_CHECK to compare the output of a sed pass
5835 over stderr against the canonical strerror string.
5837 * tests/modules.at (modules: importing): Edit the generated stderr
5838 output to canonicalize strerror output, before a comparison.
5840 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5842 Tru64UNIX perl is sloppy with namespace pollution. This patch is
5843 careful not to trip over the mess:
5845 * modules/perl.c: Some builds of perl install headers that contain
5846 `#define try __builtin_try'. Be sure to undefine that macro
5847 before `m4/hash.h' gets included, which uses the `try' symbol.
5848 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
5849 `false' before including `stdbool.h'.
5850 (DELETE): This symbol is not in m4's namespace, and is in any
5851 case only used internally...
5852 * m4/m4private.h (DELETE): ...so move it to here.
5853 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
5855 2003-10-08 Paul Eggert <eggert@twinsun.com>
5857 Don't use XMALLOC and XCALLOC. Once we install the
5858 corresponding patch into gnulib, this will fix some
5859 address-calculation overflow bugs on hosts where calloc (A, B)
5860 returns garbage when A*B overflows.
5862 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
5863 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
5864 xmalloc, XCALLOC with xcalloc.
5865 * m4/m4.c (m4_create): Likewise.
5866 * m4/m4private.h (m4_symbol_value_create): Likewise.
5867 * m4/output.c (m4_output_init): Likewise.
5868 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
5869 * m4/syntax.c (remove_syntax_attribute): Likewise.
5870 * src/freeze.c (reload_frozen_state): Likewise.
5871 * src/main.c (main): Likewise.
5873 2003-10-07 Gary V. Vaughan <gary@gnu.org>
5875 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
5876 gnulib/acm4 directories for aclocal m4 macros.
5877 * gnulib/Makefile.am (EXTRA_DIST): Removed.
5878 (MAINTAINERCLEANFILES): Add Makefile.in.
5879 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
5881 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
5882 * gnulib/import: New file. Temporary script for updating gnulib
5883 imported files, until gnulib-tool is working.
5884 * gnulib/config/codeset.m4, gnulib/config/error.m4,

5921 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
5922 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
5923 gnulib/import script.
5924 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

5929 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
5930 gnulib with gnulib/import script.
5931 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
5932 guards ready for gnulib-tool to autoupdate on import.

5934 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

5937 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,

5958 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
5959 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
5962 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
5963 Gary V. Vaughan <gary@gnu.org>
5965 * bootstrap: Separate options.
5966 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
5967 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
5969 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
5970 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
5971 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
5972 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
5973 $(LTLIBINTL) for gettext support on cygwin.
5974 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
5975 have $(LTLIBINTL) from the preloaded module la files.
5976 * README: Remove the warning about using --disable-nls on Windows
5979 2003-09-15 Gary V. Vaughan <gary@gnu.org>
5981 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
5982 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
5985 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5987 * doc/STYLE: Document the gnulib header naming conventions, and
5989 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
5990 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
5991 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
5993 * gnulib/m4/Makefile.am: Remove the rules to build these headers.

5996 module from CVS gnulib.
5997 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
5998 (gl_FUNC_STRTOL): In favour of the module macro.
6000 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6002 Replace the getopt code with CVS gnulib getopt. The source files
6003 detect whether they are in a glibc environment and preprocess away
6004 all of the code if there is a system getopt, so we can compile
6005 them into the m4 executable unconditionally:
6007 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6008 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6009 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6011 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6013 * src/Makefile.am: Adjust.
6014 * src/main.c: Always include our shipped getopt.h.
6015 * po/POTFILES.in: Use new location of getopt.c.
6017 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6019 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6020 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6021 in this directory automatically.
6022 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6024 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6026 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6028 * modules/Makefile.am (pkglibexecdir): Set it here.
6029 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6031 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6032 Import regex module from CVS gnulib.
6033 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6034 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6035 do extra substitutions for Makefile.
6036 * configure.ac: Use it.
6037 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6038 from regex_.h if necessary.
6039 * m4/system_.h: Include the correct version of regex.h.
6040 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6042 * po/POTFILES.in: Use new location of regex.c.
6044 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6045 realloc.c: automake distributes these files already.
6047 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6049 Replace the xstrzdup code by importing the xstrndup module from
6050 CVS gnulib, along with its dependencies: strndup and strnlen:
6052 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6053 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6055 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6056 gnulib/config/strndup.m4: Ditto wrt strndup.
6057 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6059 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6060 However, contrary to gnulib, we install xstrndup.h.
6061 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6062 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6063 is an artifact of the old m4 portability layer.
6064 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6065 * m4/system_.h: Include xstrndup.h.
6066 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6068 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6070 Reimport the latest xalloc module from CVS gnulib, and adjust the
6071 m4 sources to take advantage of xalloc xfree. Also create a new
6072 macro DELETE with the same semantics as the old m4 XFREE macro,
6073 and carefully tweak callers:
6075 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6077 * m4/utility.c (xfree): Removed. This function is now supplied by
6079 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6080 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6081 * m4/symtab.c (m4_symtab_create): Ditto.
6082 * m4/system_.h: Removed XFREE redefine.
6083 (DELETE): New macro with same functionality as the original m4
6084 XFREE macro, but based on xalloc.h now. Changed all callers.
6085 * src/main.c (main): Use XMALLOC macro.
6086 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6088 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6090 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6092 Import the xalloc module from CVS gnulib, along with its
6093 dependencies: exitfail, malloc and realloc. We had different
6094 semantics for our XFREE and a function xfree() not supplied by
6095 gnulib, so also a bit of work to keep everything running
6098 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6099 (gl_XALLOC): Use gnulib equivalents.
6100 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6101 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6102 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6103 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6105 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6106 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6107 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6109 (pkgincdir): Removed. Use pkgincludedir instead.
6110 * m4/m4private.h (XFREE): xfree already checks for NULL.
6111 * m4/system_.h: Use xalloc module, and remove macros already
6112 supplied by xalloc.h.
6113 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6114 moved the old definition from m4/xmalloc.c to here for now.
6116 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6118 Import the error and progname modules from CVS gnulib. Our old
6119 error.c subsumed the functionality of both, so a little adjustment
6120 was required to accomodate the split in sources. Also added more
6121 wrapper macros to choose between a system installed error.h or our
6122 shipped gnulib error module:
6124 * m4/error.c, m4/error.h: Removed.
6125 * m4/Makefile.am: Adjust.
6126 (pkgincdir): Removed. Use pkgincludedir instead.
6127 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6128 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6130 * gnulib/m4/progname.c: Imported from CVS gnulib.
6131 * gnulib/m4/progname.h: Ditto.
6132 * src/main.c: Adjust to use progname module.
6133 * gnulib/m4/error.c: Imported from CVS gnulib.
6134 * gnulib/m4/error_.h: Ditto.
6135 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6136 if appropriate, and link a local error.h if the system version is
6138 (libgnu_la_SOURCES) Add progname module sources.
6139 * gnulib/config/error.m4: Imported from CVS gnulib.
6140 * gnulib/config/strerror_r.m4: Ditto.
6141 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6142 to have ERROR_H for Makefile substitutions and tell system.h
6143 whether the system error.h should be used, or a locally installed
6145 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6147 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6149 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6150 s/gettext_.h/gettext.h/.
6152 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6153 automake have been fixed.
6155 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6156 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6157 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6158 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6160 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6162 The gnulib obstack module requires the gnulib gettext module for
6163 systems that do not have GNU gettext installed. Because we use
6164 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6165 that directory incase it clashes with the system gettext.h. This
6166 delta uses gettext_.h and extra rules in the Makefile to make a
6167 link to gettext.h when needed:
6169 * Makefile.am (auxdir): Removed. No longer used.
6170 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6171 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6173 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6174 Makefile based build.
6175 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6176 of the macros are kept.
6177 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6178 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6179 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6180 distributes these automatically.
6181 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6182 warning from automake-1.7a.
6183 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6184 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6186 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6187 wrt. m4_FUNC_OBSTACK.
6188 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6189 wrt. m4_sys_STACKOVF.
6190 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6191 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6192 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6193 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6195 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6196 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6197 gettext.h link on deficient systems.
6198 (pkginc_HEADERS): Mention $(GETTEXT_H).
6199 (EXTRA_HEADERS): Mention gettext.h.
6200 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6201 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6202 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6203 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
6204 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
6205 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
6206 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
6207 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
6208 gnulib/config/po.m4, gnulib/config/progtest.m4,
6209 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
6210 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
6212 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6214 We can't mirror the gnulib directory structure here, since we need
6215 to be able to eg. `#include <m4/obstack.h>' from our source files,
6216 which is much easier if the local obstack.h is created in a
6217 directory named m4. Rather than trying to symlink everything into
6218 the m4 directory, now we build a libtool convenience library from
6219 the sources we get from gnulib and link that with libm4.la:
6221 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6222 * gnulib/config/unlocked-io.m4: Ditto.
6223 * gnulib/m4/unlocked-io.h: Ditto.
6224 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6225 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6226 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6227 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6228 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6229 * m4/Makefile.am: Adjust.
6230 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6231 macros we redistribute.
6232 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6233 library among others.
6234 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6235 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6236 * config/m4-obstack.m4: Adjust.
6237 * po/POTFILES.in: Adjust.
6238 * configure.ac: Reformatting. Call newly imported gnulib macros.
6239 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6240 bogus calls of `#include "m4.h"'.
6241 * Makefile.am: INCLUDES has been deprecated in favour of
6243 * m4/Makefile.am: Ditto.
6244 * modules/Makefile.am: Ditto.
6245 * src/Makefile.am: Ditto.
6247 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6249 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6251 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6253 Migrate the obstack support into the gnulib directories for easy
6254 synchronisation with upstream files in gnulib:
6256 * config/gnu-obstack.m4: Moved from here...
6257 * config/m4-obstack.m4: ...to here.
6258 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6259 * m4/obstack.c, m4/obstack_.h: Moved from here...
6260 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6261 * po/POTFILES.in: Adjust.
6262 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6263 * m4/Makefile.am: Add a whole new section to link the obstack
6264 sources from the gnulib tree if necessary.
6265 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6267 * config/m4-obstack.m4: Rewrite as a wrapper for
6268 gnulib/m4/obstack.m4.
6270 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6272 GNU M4 currently builds with a number of files adapted from
6273 upstream sources. Recently the gnulib project on savannah.gnu.org
6274 has pulled together a great many of these externally maintained
6275 files. This delta is the beginnings of isolating those files
6276 maintained in gnulib to make it easy to synchronise M4 with the
6277 upstream files prior to releases.
6279 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6281 (SUBDIRS): Added new gnulib subdirectory.
6282 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6283 * config/stdbool.m4: Moved from here...
6284 * gnulib/m4/stdbool.m4: ...to here.
6285 * m4/stdbool_.h: Moved from here...
6286 * gnulib/lib/stdbool_.h: ...to here.
6287 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6289 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6290 code to work with new stdbool_.h location.
6291 (gnulib_srcdir): New.
6293 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6295 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6296 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6298 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6299 (EXTRA_DIST): Use it.
6301 * bootstrap: CVS autoreconf leaves file droppings. Remove
6302 aclocal.m4t incase autoreconf doesn't.
6304 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6306 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6307 the other gnulib imports, renamed to m4/obstack_.h.
6308 * m4/obstack.c: Updated from CVS gnulib.
6309 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6310 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6311 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6312 about vpath already, and $top_srcdir upsets CVS Automake, so the
6313 $top_srcdir reference was removed.
6315 * m4/system-h.in: For consistency with the gnulib imports, renamed
6317 * m4/Makefile (EXTRA_HEADERS): Adjust.
6318 * configure.ac (AC_CONFIG_FILES): Adjust.
6320 * m4/stdbool_.h: New file from gnulib for systems without their
6322 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6323 * config/stdbool.m4: New file. Macros from gnulib for same.
6324 * configure.ac: Use it.
6326 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6328 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`
6329 * config/gmp.m4: Ditto.

6375 * src/main.c: Ditto.
6376 * src/stackovf.c: Ditto.
6378 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6379 ac_default_headers is an autoconf internal variable.
6380 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6381 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6383 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6384 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6387 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6389 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6391 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6392 possible or faking one with a typedef. Changed all callers.
6394 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6396 Still cleaning up the users' module API, by taking out the stuff
6397 that isn't used by any existing modules, and moving specialised
6398 functions out of libm4 and into the module they are used by.
6400 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6401 * m4/utility.c (m4_skip_space): ...to here the home of its only
6402 use, made static and renamed to `skip_space'. Changed all
6404 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6405 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6406 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6408 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6410 * modules/gnu.c (builtin_syntax): Import and use in this
6411 builtin implementation.
6412 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6414 * m4/macro.c (trace_flush): Except here where the macro is now
6416 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6417 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6419 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6420 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6422 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6424 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6425 compiler based AC_CHECK_HEADER that was introduced in
6427 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6428 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6429 * configure.ac: Use renamed M4_AC_LIB_GMP.
6431 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6432 macro that requires arguments! This stops the shell's bad
6433 substitution error at configure time.
6435 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6436 variables to the testsuite shell. Set the value of USE_GMP so
6437 that the gmp test will run!
6438 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6440 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6442 Libltdl already has an excellent mechanism for accessing C symbols
6443 in modules. Lets use that! Remove all the exporting cruft and
6444 just use lt_dlsym in conjunction with a few conventions to
6445 simplify module writers' jobs. Also removed the table address
6446 caching code and otherwise simplified the module loader quite a
6447 bit. To access exported symbols in other modules, first the
6448 exporting module must name the symbols <modname>_LTX_<symname>,
6449 and the importing module must define a function type called
6450 <symname>_func. The importer then adds
6451 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6452 that wishes to call out to the exported functions. Care must be
6453 taken that <symname> is non-NULL in the importing module incase
6454 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6455 definition was in the importers source. Study
6456 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6457 m4_module_import will attempt to automatically load a module
6458 required for symbol access if it is not loaded already.
6460 * TODO: Removed the items fixed in this delta.
6461 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6463 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6464 * m4/module.c (m4_module_unload): Use it.
6465 * src/freeze.c (reload_frozen_state): Ditto.
6466 * m4/m4module.h (m4_export): Deleted. Removed all references.
6467 (M4_MODULE_IMPORT): New user convenience macro for importing
6468 arbitrary symbols from other modules.
6469 * m4/module.c (m4_module_import): New function to service
6470 M4_MODULE_IMPORT macro.
6471 (module_data): Removed. Looking up the tables on demand with
6472 lt_dlsym, rather than caching their addresses here simplifies the
6474 (m4_get_module_builtin_table, m4_get_module_macro_table):
6475 Removed. Changed all callers.
6476 (set_module_macro_table, set_module_builtin_table): Renamed to
6477 install_macro_table and install_builtin_table respectively, and
6478 simplified now that the cache is no more.
6479 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6480 import m4_dump_symbols from the m4 module.
6481 (builtin_esyscmd): Likewise for m4_set_sysval and
6483 * modules/m4.c (m4_export_table): Removed. Functions are
6484 addressed with the new mechanism which doesn't need this.
6485 (m4_set_sysval): New exported accessor function to prevent
6486 problems with variable access on inferior architectures.
6487 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6488 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6489 that we can have some type safety.
6490 * modules/modtest.c (export_test): C level exported function for
6491 testing the new import mechanism.
6492 * modules/import.c: New file for the import end of the test.
6493 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6494 * tests/modules.at: New test cases for intermodule symbol
6497 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6499 * m4/m4module.c (m4_string): Moved from here...
6500 * m4/m4private.c (m4_string): ...to here.
6502 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6504 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6506 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6507 already available to module writers through
6508 m4_{get,set}_nesting_limit_opt(), so moved from here...
6509 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6510 (m4_create): Use it.
6512 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6514 Aside from auditing path.c for m4module.h api obfuscation, this
6515 delta introduces the concept of private struct members in opaque
6516 data types to GNU m4: See the STYLE file for details.
6518 * TODO: Remind ourselves that a rewrite of path.c is needed.
6519 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6521 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6522 here and renamed. These type definitions are for internal api use
6523 only. Changed all callers.
6524 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6526 * m4/path.c (search_path_env_init, search_path_add): ...to here
6527 and renamed. These calls were never used outside this file.
6528 Changed all callers.
6529 (dirpath): Moved functionality of this static declaration...
6530 * m4/m4private.h (struct m4): ...to this new internal only
6531 search_path field. Changed all callers.
6532 (m4__get_search_path): Added new internal api accessor.
6533 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6534 (m4_include_init): Removed...
6535 * m4/m4.c (m4_create): ...because the new m4 field is now
6537 (m4_delete): Recycle search_path memory.
6538 * src/main.c (main): Don't call m4_include_init now that it's
6540 * doc/STYLE: Document convention for private fields in opaque
6543 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6545 Sometimes exporting the address of a symbol from a module isn't
6546 enough for other modules to call that symbol correctly. If
6547 custom data types are used for function parameters, they need to
6548 be known to the caller. This change introduces the concept of
6549 $(prefix)/include/modules/$(modulename).h to declare those
6550 structures. Also we move m4_dump_symbols from libm4 to the m4
6551 module to show this concept in action.
6553 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6554 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6555 exporting data structures from modules/m4.c.
6556 * modules/m4.c, modules/gnu.c: Include it.
6557 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6558 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6560 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6562 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6563 ...to here, with slight renaming.
6564 (m4_export_table): Prototype and add m4_dump_symbols.
6565 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6566 definition of m4_dump_symbols.
6567 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6568 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6570 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6572 Create an export table in modules/m4.c in readiness for beefing up
6573 the module loader to track module exports and imports.
6575 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6576 * m4/debug.c (m4_debug_flush_files): Moved...
6577 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6578 * modules/gnu.c (builtin_esysval): Use it.
6579 * m4/m4module.h (m4_export): New type for declaring module symbols
6581 * modules/m4.c (m4_export_table): List symbols exported from this
6582 module for use by other modules.
6584 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6586 An experiment: There is loads of code in libm4 which should be in
6587 the m4 module, but is also used by another module. Just because
6588 some linkers won't cope with calls across dynamic runtime loaded
6589 objects I initially left the code in libm4. It will tidy the
6590 module api immensely if this code moves to the right place, I just
6591 need to remember to invent a suitable calling mechanism at some
6592 point. For now, only modules that are statically linked and
6593 preloaded will get this treatment, so the only platforms that will
6594 break are those that require all symbols to be resolved at link
6597 * TODO: Reminder that what I am doing could reduce portability
6598 unless I do something more robust later.
6599 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6600 * m4/utility.c (m4_sysval): No longer declared in libm4.
6601 * modules/Makefile.am: Reformatting.
6602 * modules/m4.c (m4_sysval): Declare it at place of use.
6603 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6605 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6607 * m4/m4module.h: Reformatting and rearranging lines a bit.
6608 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6610 (m4_call_macro, m4_expand_input): Renamed...
6611 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6613 (m4_expansion_level, m4_process_macro): Moved...
6614 * m4/macro.c (expansion_level, process_macro): ...to here, and
6617 * m4/m4module.h (program_name): Not used by modules at all, so
6619 * src/main.c (program_name): ...to here.
6620 (print_program_name): Renamed...
6621 (print_program_name_CB): ...to conform to the STYLE guide.
6623 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6625 More refactoring of the m4module.h API. Replace #defines with an
6626 enum, and move non-public functions out of the public API.
6628 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6630 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6631 * m4/debug.c (m4_debug, trace): Moved...
6632 * m4/m4private.h (struct m4): ...to fields of this struct.
6633 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6635 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6636 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6637 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6638 * m4/m4module.h (m4_context_field_table): Add entries for new
6639 debug_file and trace_messages fields.
6640 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6641 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6642 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6643 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6644 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6645 (m4_is_debug_bit): New macro to simplfy checks against the debug
6647 (m4_trace_format, m4_trace_header, m4_trace_flush)
6648 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6650 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6651 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6652 * m4/macro.c (trace_format, trace_header, trace_flush)
6653 (trace_prepre, trace_pre, trace_post): ...to these newly static
6654 functions, since they are only ever used from this file. Changed
6657 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6659 Change the macros for checking syntax so that matching against
6660 multiple possible syntax classes can be done with a single
6661 comparison some of the time. The various classes are now bits of
6662 an int that can be checked with bitwise logic operators.
6664 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6665 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6666 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6667 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6668 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6669 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6670 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6671 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6672 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6673 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6674 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6675 Replace all calls with invocations of these...
6676 (m4_is_syntax, m4_has_syntax): ...New macros.
6677 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6678 is no longer required with new macros. Changed all callers.
6680 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6682 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6683 values are returned as part of the internal interface, so they
6685 * m4/private.h: ...to here.
6686 * m4/macro.c (expand_token): Check for out of range
6687 m4_peek_input() results before looking up in the syntax table.
6688 (collect_arguments): Ditto.
6690 * NEWS: Note `$' syntax class.
6692 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6693 Gary V. Vaughan <gary@gnu.org>
6695 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6696 --traditional `define' now smashes all the definitions.
6698 * NEWS: Explain this.
6699 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6700 (Extensions): Explain that extensions that are incompatible with
6701 POSIX are disabled if POSIXLY_CORRECT is set.
6702 (Incompatibilities): Remove.
6703 (Define, Other Incompat): Explain difference
6704 between GNU and POSIX behavior of define, pushdef, popdef.
6705 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6706 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6707 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6708 (m4_get_posixly_correct_opt): New macro.
6709 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6711 * modules/m4.c (builtin_functions): defn now takes any number of args.
6712 (builtin_define): Smash all the definitions if
6714 (builtin_defn)): Allow any number of arguments.
6715 (builtin_undivert): Do not allow nonnumeric arguments
6717 * src/main.c (main): Set posixly-correct behavior if either
6718 POSIXLY_CORRECT is set, or if -G is given.
6719 * tests/builtins.at: New test for smashed definitions.
6721 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6723 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6724 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6725 not to slow the parser down.
6726 (M4__IS_STRING): New macro to test string syntax class membership.
6727 * m4/syntax.c: Adjust docucomment.
6728 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6729 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6730 * m4/input.c (init_builtin_token): Comment typo.
6731 (m4__next_token): Comment typo.
6732 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6733 by using the new M4__IS_STRING macro.
6734 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6735 variable references in macro expansions.
6737 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6738 (Epatsubst and Patsubst): Typo.
6741 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6743 Move the global variables that pertain to syntax to a new `struct
6744 m4_syntax_table', and then add one of these to `struct m4'. The
6745 ripple effect through the code to both change formerly global
6746 references, and make sure a suitable context is available in
6747 lexical scope is disproportionately large compared to the size of
6748 the change proper. This change is a large part of decoupling
6749 syntax.c from the rest of the code that uses it.
6751 * m4/m4private.h (struct m4): Add a syntax field.
6752 * m4/m4.c (m4_create): Initialise it,
6753 (m4_delete): Recycle it.
6754 (m4_get_symtab): Remove hand coded version...
6755 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6757 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6758 can generate m4_get_symbol_table. Add a new row for
6759 m4_get_syntax_table.
6760 (M4SYNTAX): Syntactic sugar for module writers.
6761 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6762 (m4_syntax_table): New home for syntax related formerly global
6764 * m4/m4private.h (struct m4_syntax_table): Define it.
6765 * m4/input.c (m4_input_init): Initialisation of these formerly
6766 global variables moved...
6767 * m4/syntax.c (m4_syntax_create): ...to here.
6768 * m4/input.c (m4_input_exit): And similarly, recycling of the
6769 memory used by those values moved...
6770 * m4/syntax.c (m4_syntax_delete): ...to here.
6771 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6772 Moved to m4/m4private.h.
6773 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6774 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6775 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6776 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6777 objects. Changed all callers that used to directly access the
6779 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6780 Removed and incorporated into m4_syntax_table structure.
6781 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6782 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6783 instead of requiring a `struct m4' to generate its own errors.
6784 Changed all callers.
6785 * src/main.c (main): Now that the syntax table is initialised as
6786 part of m4_create, we have to manually wipe the syntax entries if
6787 we are about to read a frozen file.
6789 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6791 * doc/STYLE: Added notes on callback naming schemes.
6793 * m4/module.c (m4_set_module_macro_table)
6794 (m4_set_module_builtin_table): Declarations weren't changed when
6795 definitions were renamed on 2003-06-19.
6797 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6798 neither used nor particularly appropriate since it exposes the
6799 internal workings of the hash module. I haven't yet decided
6800 whether to remove it entirely.
6802 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6804 Two related changes, and a huge knockon effect throughout the
6805 source: Moved the option variables out of global space and into
6806 `struct m4'; made `m4_symtab' a real datatype, so that its api
6807 is not marred passing `struct m4' around just so it can decide
6808 whether to keep traced symbol names or not. Added setters and
6809 getters for the formerly global option variables, and obviously
6810 changed a vast number of functions to take a `struct m4' and use
6811 the getter funcs to find option values.
6813 * m4/utility.c (interactive, sync_output, debug_level)
6814 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
6815 (max_debug_argument_length, warning_status, nesting_limit)
6816 (discard_comments): Removed.
6817 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
6818 (debug_level, max_debug_argument_length, prefix_all_builtins)
6819 (suppress_warnings, discard_comments, interactive, sync_output):
6820 Removed from here...
6821 * m4/m4private.h (struct m4): ...and equivalent fields added to
6823 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6824 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6825 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6826 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6827 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
6828 macros for the new fields.
6829 * m4/m4module.h (m4_context_field_table)
6830 (m4_context_opt_bit_table): Helper macros used to generate
6831 prototypes, setters and getters for new option fields
6833 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6834 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6835 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6836 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6837 (m4_get_interactive_opt, m4_get_sync_output_opt)
6838 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
6839 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
6840 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
6841 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
6842 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
6843 setter and getter functions generated by cpp from
6844 m4_context_field_table and m4_context_opt_bit_table, exported as
6845 part of the module api. Changed all callers.
6846 * m4/symtab (struct m4_symtab): Used as the concrete type for
6848 (m4_symtab_create): Allocate and initialise a new struct.
6849 (m4_symtab_apply): New function that works like m4_hash_apply, but
6850 with different callbacks specific to symbol tables. Changed all
6852 (symbol_destroy, arg_destroy, arg_copy): Renamed
6853 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
6854 they have unused parameters for a reason!
6855 (dump_symbol_CB): New callback to dump the contents of a single
6857 (symtob_dump): Rewritten in terms of dump_symbol_CB.
6858 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
6859 Changed all callers.
6860 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
6861 of the contained `m4_symtab' at the `no_gnu_extensions' field.
6862 Although I'm not convinced these semantics are correct, they are
6863 at least consistent with how things were before this delta. Also
6864 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
6866 2003-06-19 Gary V. Vaughan <gary@gnu.org>
6868 Tie down the interface to libm4 some more. Make more structures
6869 opaque to modules by moving them to m4private.h, and writing
6870 setters and getters. To win back the speed penalty for doing this
6871 also wrote macroized versions that do know about structure layout
6872 in m4private.h and #include that file into modules when NDEBUG is
6873 defined at compile time. There are still some accessor macros in
6874 m4private.h that need to go, but that is not necessary to clean
6877 * m4/m4module.h (m4_symbol_type): Moved...
6878 * m4/m4private.h (m4__symbol_type): ...to here.
6879 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
6880 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6881 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6882 (m4_get_symbol_func, m4_symbol_value_create)
6883 (m4_symbol_value_delete, m4_set_symbol_value_text)
6884 (m4_set_symbol_value_func): New exported api to symbols.
6885 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
6886 and m4_is_symbol_value_func.
6887 * m4/m4module.h: Prototype these guys.
6888 * m4/module.c (m4_set_module_macro_table)
6889 (m4_set_module_builtin_table): Make these static, there is no
6890 reason to pollute the api with them.
6891 * m4/m4private.h: Reformatting.
6892 (m4_get_symtab): Only define when NDEBUG is defined.
6893 (m4_get_symbol_value, m4_get_symbol_traced)
6894 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6895 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6896 (m4_get_symbol_func, m4_symbol_value_create)
6897 (m4_symbol_value_delete, m4_set_symbol_value_text)
6898 (m4_set_symbol_value_func): Macro implementations of the new
6899 functions when NDEBUG is defined.
6900 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
6901 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
6902 Superceded by the above. All callers changed.
6903 (M4ARG): Removed. This is no longer different to the
6904 m4/m4module.h definition.
6905 * modules/gnu.c, modules/m4.c: Only include m4private.h when
6906 NDEBUG is defined. That way we exercise the same (albeit slower)
6907 api that external modules must use.
6909 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6911 Renamed some of the types and their accessors to make more sense.
6912 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
6913 has a stack of SYMBOL_VALUEs.
6915 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
6916 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
6917 m4_get_symbol_value_type, m4_get_symbol_value_text,
6918 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
6919 Changed all callers.
6920 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
6921 (m4_get_token_type): Renamed
6922 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
6923 to the internal api.
6924 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
6926 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
6927 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
6928 (m4__token_type): Moved here from m4module.h.
6929 (m4__next_token): Renamed from m4_next_token.
6930 * m4/symtab.c: Removed some of the parameterised macro support
6931 functions for modularisation later.
6932 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
6933 m4_hash_dup to perform a true deep copy of the SRC.
6934 (arg_copy): Callback for m4_symbol_value_copy.
6935 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
6936 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
6937 m4_get_symbol_value_func. Changed all callers.
6939 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6941 Tidy up style of hash.[ch] in accordance with doc/STYLE.
6943 * m4/hash.c: Internal symbol renaming and formatting.
6944 (m4_hash_dup): New function to facilitate deep copies of hash
6946 (m4_hash_apply_func): Returns a void* now, which is a richer type
6947 for returning exceptions (NULL means keep going).
6948 (m4_hash_apply): Ditto.
6949 * m4/hash.h: Declare exported symbols with an explicit extern.
6952 2003-06-17 Gary V. Vaughan <gary@gnu.org>
6954 Still refactoring furiously. This delta represents a change in
6955 semantics to symtab.c. Instead of building temporary m4_tokens
6956 in the caller, and copying fields in the methods, we now create
6957 the actual m4_token for hashing in the caller so the methods just
6958 slot them in directly. Also, this means that we don't lookup a
6959 symbol and get back an allocated but VOID token to copy fields
6960 into, we create the token we want to push and pass that to
6961 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
6962 a few other small changes to stop knowledge of the implementation
6963 of symtab.c leaking out into other files.
6965 * m4/macro.c (expand_argument): Comment typo corrected.
6966 * m4/symtab.c (symtab_fetch): New function to fetch the address of
6968 (m4_symbol_pushdef): Take an extra value parameter and use this
6969 directly as the new top of the value stack. All callers changed
6970 to build a token and pass responsibility for memory in, rather
6971 than copying as we used to.
6972 (m4_symbol_define): Also use the new value parameter directly as a
6973 replacement for the top of the value stack. All callers changed
6974 to build a token as above.
6975 (m4_set_symbol_traced): New function to set the traced bit on the
6976 named symbol, creating it if necessary.
6977 (symbol_popval): The guts of the old m4_symbol_popdef.
6978 (m4_symbol_popdef): Use it.
6979 * m4/builtin.c (m4_symbol_set_token): Removed,
6980 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
6982 * m4/module.c (m4_set_module_builtin_table)
6983 (m4_set_module_macro_table): ...with these more orthogonal
6985 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
6986 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
6988 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
6989 (m4_arg_signature_parse): Moved...
6990 * m4/symtab.c: ...to here.
6991 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
6992 screw something up. Moved...
6993 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
6994 actually does a proper deep copy of source to dest.
6996 2003-06-16 Gary V. Vaughan <gary@gnu.org>
6998 Further refactoring to stabilise the module API. Renaming some
6999 functions for orthogonality, and judicious definition migration to
7000 move things out of the set of exported symbols.
7002 * doc/STYLE: New file. Notes on coding style.
7003 * m4/m4module.c: Updated bitrotted docucomment at the top of the
7005 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
7006 m4_get_module_name, m4_get_module_builtin_table,
7007 m4_get_module_macro_table which are verb phrases. Changed all
7009 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7011 * m4/module.c (m4_set_module_builtin_table)
7012 (m4_set_module_macro_table): ...here, and renamed. Changed all
7014 * m4/m4module.c (m4_module_data): This...
7015 * m4/m4private.c (struct m4_module_data): ...and this...
7016 * m4/module.c (module_data) ...consolidated here and no longer
7017 exported. Changed all callers.
7019 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7021 Begin work on lifting the curse of the global variables. To start
7022 with create a `struct m4' context container, and replace
7023 `m4__symtab' with `context->symtab' throughout. This means
7024 initialising a context container in main, and adjusting many
7025 functions between main and the module entry points so that the
7026 container gets passed through. It would have been nice to
7027 defer this until after 1.5, but it has a major effect on the
7028 user's module writing ABI, so it needs to be addressed now - at
7029 least in the areas that impact the ABI. An interrelated change
7030 in the symtab API removes the dependency on a global symbol table,
7031 and instead focuses on a passed table (from the context
7034 * TODO: Reminders for finishing context functionality.
7035 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7036 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7037 global variables and eventually allow m4 to be reentrant.
7038 * m4/m4private.h (m4): Define the new structure here...
7039 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7040 don't carry the overhead of a function call.
7041 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7042 (m4): Declare type for new struct m4 objects.
7043 (M4SYMTAB): User macro to ease finding the symbol table for the
7044 current context for module developers.
7045 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7047 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7048 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7049 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7050 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7051 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7052 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7053 m4* context parameter. Changed definitions and all callers.
7054 (m4_symtab): Alias for m4_hash to decouple the
7055 m4_symtab api from m4_hash.
7056 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7058 (m4_symtab_create): New function to return an initialised
7060 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7061 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7062 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7063 instead of simply using the global m4__symtab. Changed
7064 definitions and all callers.
7065 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7066 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7067 * src/main.c (main): Create a context and use that instead of the
7068 former global m4__symtab.
7070 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7072 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7073 to the callback. Callbacks should not need to hardcode the
7074 hashtable they are working from, nor should we have to waste the
7075 userdata parameter to pass the table in.
7076 * m4/hash.h (m4_hash_apply_func): Require the initial table
7078 * m4/symtab.c (symtab_destroy): Use the passed table instead
7079 of hardcoding m4__symtab.
7080 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7081 table to arg_destroy.
7082 (arg_destroy): Use the hash parameter, ignore userdata.
7083 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7085 (traceon, traceoff): Call set_trace with the extra initial
7088 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7090 More refactoring to stabilise the module api, this time for
7091 symtab.c. Additionally, start to pay attention to function names
7092 that don't contain a verb like they should.
7094 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7095 wrapper for m4_hash_apply to decouple the symtab module from the
7097 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7098 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7100 (m4_symbol_delete): Create a macro version to save a function
7102 (m4_token_t, m4_data_t): These violate the POSIX reserved
7103 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7105 (m4_token_type): Renamed to m4_token_get_type.
7106 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7107 (m4_symtab_exit): Removed from the exported module
7109 * m4/m4private.h (m4__symtab, m4__symtab_init)
7110 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7111 renamed and added to the internal api. Changed all callers.
7112 (m4_symtab_apply): A faster macro version of the function for
7113 users of the internal api.
7114 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7115 symbol_destroy and arg_destroy.
7116 (symtab_debug): Added a prototype.
7117 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7118 so that callers in this file get the faster macro versions from
7121 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7123 Refactoring modules to rationalise the API into an external
7124 documented (eventually!) API for use by modules in the `m4_'
7125 namespace declared in m4/m4module.h, an internal API between the
7126 source files we ship (including our shipped modules) in the `m4__'
7127 namespace declared in m4/m4private.h and making the rest as
7128 cohesive as possible with liberal use of the `static' keyword.
7129 This change represents an audit to m4/module.c along these
7132 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7133 Removed. No longer used.
7134 (m4_module_close): Removed prototypes.
7135 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7136 from the exported module api...
7137 * m4/m4private.h (m4__module_init, m4__module_open)
7138 (m4__module_exit): ...and renamed and added to the internal api.
7139 Changed all callers.
7140 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7141 Centralised definitions after renaming...
7142 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7143 (M4_FINISH_SYMBOL): ...and removing from here.
7144 (m4_module_dlerror, m4_module_remove, m4_module_close)
7145 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7146 module_remove, module_close and caller_id.
7147 (MODULE_SELF_NAME): New macro to make reporting self errors
7149 (m4_module_load, module_close, module_remove): Use it.
7150 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7152 * src/main.c (main): Use it.
7154 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7156 * README: Remove references to --enable-changeword, which has been
7157 removed from the code.
7159 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7161 Getting rid of the annoying bug with configure --enable-debug,
7162 which spewed -e: command not found errors. This was an interaction
7163 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7164 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7165 branch-1-5) to get the full fix.
7167 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7168 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7169 and then use the probed value of $SED.
7170 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7171 this, it messes up the AC_REQUIRE stack.
7173 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7175 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7176 the destroy callback.
7177 (m4_arg_destroy): Use the hash address to free the hash node key
7180 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7182 First cut at formal parameters in macros.
7184 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7185 * m4/xstrzdup.c: New file.
7186 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7187 associative array of parameter names to details.
7188 (m4_symbol_token): Capture macro names with parameter lists.
7189 (m4_arg_signature_parse): And build an associative array to hang
7190 from the symbol structure to map names to details.
7191 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7192 m4_hash_resize idiom. Now that we potentially add a little hash
7193 table to many of the entries in the symbol table, added an extra
7194 arg to set the initial size. Changed all callers.
7195 (m4_hash_apply): New function that is basically a generalised
7197 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7198 all callers to call m4_hash_apply instead.
7199 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7200 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7201 m4_arg_signature association that might be attached to the symbol,
7202 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7203 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7204 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7206 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7207 (M4_IS_IDENT): Detect characters that can be safely used in
7209 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7210 * m4/macro.c: Corrected grammar in some comments. Use `token'
7211 rather than `td' for m4_token variables.
7212 (m4_process_macro): If we find a dollar followed by some
7213 M4_IS_IDENT characters, replace that with the contents of the argv
7214 entry with offset stored in the m4_token_arg associated with the
7215 collected identifier.
7217 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7219 Begin preparations for supporting formal parameters in m4 macros.
7221 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7222 the details of a formal parameter.
7223 (m4_token): Add an arg_signature member to hold a hash table for
7224 looking up formal parameters.
7225 * m4/input.c: Update more bitrotted comments.
7226 (m4_push_builtin): Initialise arg_signature member.
7227 (init_builtin_token): Copy arg_signature member.
7228 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7229 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7231 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7232 (m4_macro_pushdef, m4_macro_define): ...these, And...
7233 (m4_symbol_token): ...wrapped around this new function, which
7234 vastly simplifies the arguments required by the functions it
7236 Changed all callers.
7238 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7240 * m4/macro.c: Format changes.
7242 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7244 * m4/input.c: Updated various bitrotted comments.
7245 (m4_push_builtin): Just pass the whole m4_token, rather than
7246 extracting all the fields in the caller. This also allows us to
7247 check the token type for consistency.
7248 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7249 Renamed to builtin_funcs, builtin_peek, builtin_read,
7250 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7251 the code. Changed all callers.
7252 (struct input_block): Similarly renamed u_m member to u_b, and
7253 changed all callers.
7254 (m4_next_token): Use bzero to initialise the data fields.
7255 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7257 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7259 These changes were necessary to get m4 to build on my iBook
7260 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7261 (GCC) 3.1 20020420 (prerelease)":
7263 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7264 inclusion of module loader headers.
7265 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7266 * m4/Makefile.am: Ditto.
7267 (libm4_la_LIBADD): Added $(LTLIBINTL).
7268 * m4/utility.c (program_name): Removed declaration in favour of
7269 the one already in error.c!
7270 * m4/m4module.h (program_name): Define to program_invocation_name
7271 when using GNU C library. Use an explicit extern declaration.

7284 * m4/error.h (error, error_at_line, error_print_progname)
7285 (error_message_count, error_one_per_line): Ditto.

7318 * Makefile.am (SUBDIRS): Remove intl.
7319 (ACLOCAL_AMFLAGS): Add -I config.
7320 (EXTRA_DIST): Add config/config.rpath.
7323 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
7325 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7327 Preparations for refactoring syntax tables to allow reverse
7328 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7329 speed of normal lookups in an array of unsigned short.
7331 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7333 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7334 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7335 is for internal symbols which unavoidably pollute the global
7336 namespace, but are not published APIs.
7337 Adjusted all callers.
7338 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7339 m4_set_comment, m4_set_syntax, set_syntax_internal,
7340 unset_syntax_attribute): Moved from this file...
7341 * m4/syntax.c: New. ...to this file.
7342 Also added an m4_syntax_exit stub for orthogonality.
7343 * src/main.c (main): Use it.
7344 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7345 * m4/m4module.h: Reformatting. New prototypes.
7347 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7349 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7350 distinct from the automake release number (in that the apiversion
7351 apparently has no micro-version-component).
7352 (aclocal_apilibdir): Use it.
7354 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7356 * m4/hash.c (m4_hash_resize): New function.
7357 * m4/hash.h: Add prototype.
7358 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7359 benchmarking to find a good value for, say, autoconf. This is
7360 already a little quicker than before for me.
7362 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7363 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7365 * m4/hash.h: Adjust prototypes.
7367 2002-01-22 Akim Demaille <akim@epita.fr>
7369 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7371 * tests/Makefile.am (package.m4): New.
7372 * tests/atlocal.in: Adjust to CVS Autotest.
7373 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7374 * configure.ac: LIBOBJ is a forbidden string.
7375 Simplify AM_INIT_AUTOMAKE invocation.
7376 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7379 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7381 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7383 2001-10-19 Akim Demaille <akim@epita.fr>
7385 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7387 2001-10-19 Akim Demaille <akim@epita.fr>
7389 * m4/input.c (m4_next_token): Display where was opened what is
7392 2001-10-19 Akim Demaille <akim@epita.fr>
7394 * m4/macro.c (expand_argument): Display where was opened what is
7397 2001-10-18 Akim Demaille <akim@epita.fr>
7399 * m4/input.c, modules/m4.c: Formatting changes.
7401 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7403 * bootstrap: s/configure.in/configure.ac/
7405 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7407 * m4/symtab.c (m4_symbol_destroy): This function calls
7408 m4_symbol_popdef, which recycles a symbols memory when the last
7409 definition is popped. Since we were passing the address of the
7410 symbol name found in the symbol table, and it was being removed
7411 partway through m4_symbol_destroy() we were referencing freed
7412 memory for the balance of the function. Now we take a copy of the
7413 symbol name tring and use that as a key into the symbol
7414 table... that way if the original symbol name is freed, the copy
7417 2001-10-13 Akim Demaille <akim@epita.fr>
7419 * m4/ltdl.c: Update.
7421 2001-10-13 Akim Demaille <akim@epita.fr>
7423 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7424 Don't gettextize internal error messages.
7426 2001-10-13 Akim Demaille <akim@epita.fr>
7428 * tests/macros.at (Arity and defn): New failing test.
7429 (Arity, defn, and freeze): New.
7431 Fix `Arity and defn'.
7433 * m4/input.c (m4_push_macro): Don't forget the arity.
7434 * modules/m4.c (defn): Likewise.
7436 2001-10-13 Akim Demaille <akim@epita.fr>
7438 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7440 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7441 (Propagation of traceon, Propagation of --trace): this new file.
7443 2001-10-13 Akim Demaille <akim@epita.fr>
7445 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7446 interface instead of (name, argc...).
7447 Upon failure, specify which argument was guilty.
7450 2001-10-13 Akim Demaille <akim@epita.fr>
7452 * modules/evalparse.c: Save translators' time: don't translate
7453 internal error messages.
7454 (m4_evaluate): Simplify/normalize error messages.
7455 * doc/m4.texinfo (Eval): Adjust.
7457 2001-10-13 Akim Demaille <akim@epita.fr>
7459 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7460 where no checking is needed.
7461 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7462 interface instead of (name, argc...).
7464 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7467 2001-10-13 Akim Demaille <akim@epita.fr>
7469 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7470 exclude the builtin name from the count.
7471 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7472 calling ifelse with a single argument is valid.
7473 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7474 with 1 and 2 args, mostly to strengthen the test suite.
7476 2001-10-13 Akim Demaille <akim@epita.fr>
7478 * m4/output.c (m4_make_diversion, m4_insert_file)
7479 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7481 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7483 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7484 since we call these things builtins in the rest of the code!
7486 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7488 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7490 Rather than forcing each builtin definition to manage its own
7491 argument range checking, tabulate the maxima and minima for all
7492 builtins in each module. This forces us to consider what the
7493 valid ranges for each builtin should be, and moves the checking
7494 code out of each builtin implementation and into the builtin
7495 caller infrastructure.
7497 * m4/m4module.h (struct m4_builtin): Add argument minima and
7499 * m4/m4private.h (struct m4_token): Reflect them here too.
7500 * m4/input.c (struct input_block): ...and here.
7501 (m4_token_copy): New function for token copying.
7502 (init_macro_token): Copy them from a token to the input stack.
7503 (m4_next_token): Don't forget to initialise them for text
7505 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7506 check argument counts before calling the builtin handler.
7507 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7508 (m4_symbol_macro): Likewise.
7509 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7510 parameters. Updated all callers.
7511 (m4_builtin_define): Ditto.
7512 (m4_macro_pushdef, m4_macro_define): Ditto.
7513 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7514 * modules/evalparse.c: Declare argument counts for defined
7515 builtins and remove explicit calls to m4_bad_argc().
7516 * modules/gnu.c: Ditto.
7517 * modules/load.c: Ditto.
7518 * modules/m4.c: Ditto.
7519 * modules/modtest.c: Ditto.
7520 * modules/mpeval.c: Ditto.
7521 * modules/perl.c: Ditto.
7522 * modules/shadow.c: Ditto.
7523 * modules/stdlib.c: Ditto.
7524 * modules/time.c: Ditto.
7527 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7529 The trace semantics now attach the trace bit to a symbol name.
7530 For as long as a traceon(`foo') is active, calls to foo will be
7531 traced regardless of intervening undefines or module unloads.
7532 Fixed the flag propogation issues differently to the fixes
7533 reverted with the last attempt at nailing down trace:
7535 * m4/m4private.h: This file is not visible outside of the m4
7536 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7537 on typing. Updated all clients.
7538 (m4_token): New typedef contains the fields that need to be passed
7539 around with the low level tokeniser.
7540 (m4_token_data): Removed.
7541 (m4_symbol): Now contains the traced flag again.
7542 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7543 the trace bit set. This change is contained entirely within this
7544 module and doesn't leak out into the callers. Updated all
7546 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7547 new fields in m4_token. Updated all clients.
7548 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7549 that `groks_macro_args' and `blind_if_no_args' flags are retained
7550 when defn() results are passed around in m4 code. Updated all
7552 (m4_builtin_define): Ditto.
7553 (m4_macro_pushdef, m4_macro_define): Ditto.
7554 * m4/input.c (struct input_block): Add a flags field to facilitate
7556 (m4_push_macro): ...use it.
7557 (init_macro_token): Retrieve it.
7558 (m4_next_token): Initialise it.
7559 * m4/macro.c (expand_argument): Copy it.
7560 * m4/m4module.h: Adjust.
7561 * tests/builtins.at: Adjust the expected output of the trace
7562 tests to reflect the change in semantics.
7563 * tests/modules.at (modules: trace): Check that unloading a
7564 module which supplies a traced symbol definition doesn't lose te
7567 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7569 * modules/gnu.c (m4_macro_table): Display the timetamp when
7570 expanding __m4_version__.
7572 * configure.ac (--with-modules): Forgot a comma in the
7573 AC_HELP_STRING parameter list.
7575 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7577 * bootstrap: Remove aclocal.m4t when it is no longer required.
7579 2001-10-05 Akim Demaille <akim@epita.fr>
7581 * tests/Makefile.am: Adjust for gnuprog2.
7582 * tests/m4.in: There can be a leading path.
7583 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7584 * tests/testsuite.at: Adjust to the most recent Autotest.
7585 (AT_CHECK_M4_FILTER): Fix and rename as...
7587 * tests/others.at: Use it.
7589 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7590 variable in shell scripts, one uses `$'...
7592 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7594 * configure.ac: `rm -f $m4_getopt_h' was lost.
7596 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7598 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7599 time. Define it for config.h in order to...
7600 * src/main.c (main): ...display the timestamp for --version.
7602 2001-10-04 Akim Demaille <akim@epita.fr>
7604 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7605 previous builtins `regexp' and `patsubst'.
7606 (regexp, patsubst): Use them.
7607 (eregexp, epatsubst): New builtins.
7608 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7609 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7610 (Extensions): More info on REs.
7612 2001-10-04 Akim Demaille <akim@epita.fr>
7614 * modules/modtest.c (init_handler): Consistently output to stderr.
7615 (finish_handler): New.
7616 (test): The `if' is an `assert'.
7617 * tests/modules.at: Adjust.
7619 2001-10-04 Akim Demaille <akim@epita.fr>
7621 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7623 2001-10-01 Akim Demaille <akim@epita.fr>
7625 * tests/generate.awk: Tag the tests with `documentation'.
7626 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7627 Use the make the existing modtest tests more uniform, and complete
7628 the set of possibilities.
7630 2001-10-01 Akim Demaille <akim@epita.fr>
7632 * config/gmp.m4: Consult the user before using GMP: use
7634 * configure.ac: Adjust.
7635 * modules/gmp.c: No protection needed as the module is not built
7638 2001-10-01 Akim Demaille <akim@epita.fr>
7640 * tests/generate.awk: Remove debugging code.
7641 (fatal): Specify the current location.
7643 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7644 * modules/gnu.c, modules/m4.c: Use M4ARG.
7646 2001-10-01 Akim Demaille <akim@epita.fr>
7648 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7649 (m4_regexp_compile): New.
7650 (regexp, patsubst): Use it.
7652 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7654 Reinstate the memory handling improvements from the patch I just
7655 reverted. Relevant ChangeLog entries repeated here:
7657 * m4/module.c (m4_module_remove): New function that holds the core
7658 of the old m4_module_unload.
7659 (m4_module_unload): Use it.
7660 (m4_module_unload_all): When we know the modules will never be
7661 used again (i.e. on exit), free up as much module memory as
7662 possible. There are still some artifacts from resident modules
7663 living inside ltdl.c, but everything else is freed.
7664 * m4/debug.c (m4_debug_exit): Free memory allocated in
7666 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7667 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7668 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7669 * m4/m4module.h: Updated prototypes.
7670 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7671 * m4/hash.h: Updated prototypes.
7672 * src/main.c (main): Use all these new functions to clean up as
7673 much memory as possible before exit.
7675 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7677 Reverted my large patch for removing the old m4_symbol
7678 structure on 2001-09-20. We are still not happy about the way
7679 trace works in conjunction with defn and undefine, and leaving
7680 the reverted patch active prevents us from moving the traced
7681 bit from the definition back to the symbol.
7683 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7685 * configure.in: Moved to...
7686 * configure.ac: ...here. Added a libtool like timestamped
7687 banner, and tidied up the libltdl cruft.
7688 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7689 * modules/Makefile.am (INCLTDL): Removed. This is required
7690 only when libltdl is configured in a subdirectory.
7691 * src/Makefile.am: Ditto.
7692 (LIBADD_DL): No need to add this again, libtool already knows
7693 that libm4.la depends on it.
7694 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7697 * TODO: stackovf.c is basically broken.
7698 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7700 2001-09-28 Akim Demaille <akim@epita.fr>
7702 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7704 2001-09-27 Akim Demaille <akim@epita.fr>
7706 * tests/m4.in: Don't use short options.
7707 Simplify the stderr signature normalization.
7709 2001-09-27 Akim Demaille <akim@epita.fr>
7711 tests/m4 shall be position independent.
7715 * tests/testsuite.at: No args to AT_INIT.
7716 * configure.in, tests/Makefile.am: Adjust.
7718 2001-09-22 Akim Demaille <akim@epita.fr>
7720 Autotest has changed again.
7722 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7723 (package.m4): Remove.
7724 * configure.in: Adjust to LIBADD_GMP.
7726 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7728 * config/gmp.m4 (AC_ARG_WITH): Removed.
7729 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7730 (AC_LIB_GMP): When performing a test compile against libgmp,
7731 include the header gmp.h if possible, and link against -lgmp. If
7732 they both work define USE_GMP.
7733 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7734 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7737 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7739 * m4/evalparse.c: Moved to...
7740 * modules/evalparse.c: ...here. This code is shared between
7741 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7742 the libm4 API with its details. Moderately rewritten to interface
7743 into its clients more simply.
7744 * m4/eval.c: Deleted. Migrated functionality to...
7745 * modules/m4.c: ...here.
7746 (builtin_eval): Implemented in terms of the new interface style.
7747 * modules/mpeval.c (builtin_mpeval): Ditto.
7748 * m4/m4module.h: Removed references to the former m4/eval.c.
7749 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7750 (EXTRA_libm4_la_SOURCES): Deleted.
7751 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7752 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7754 2001-09-20 Akim Demaille <akim@epita.fr>
7756 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7758 By default, use gmp.
7760 * configure.in: Adjust.
7761 Use Automake conditionals for USE_GMP.
7762 Always compute sizeof (long long int).
7763 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7764 before, it was used _only_ if mpeval was not activated.
7765 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7766 (mpeval_la_LIBADD): New macros.
7767 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7769 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7770 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7773 2001-09-20 Akim Demaille <akim@epita.fr>
7775 * tests/Makefile.am (package.m4): New.
7776 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7778 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7780 More cleanup. After the last patch, m4_symbol holds nothing but
7781 the head of a chain of m4_token_data. So I have removed the old
7782 m4_symbol, so that m4_token_data chains are stored directly in the
7783 value cell of a hash table node. But there's more... m4_symbol
7784 was a more natural name for the symbol value cell, and now that it
7785 is gone I have renamed the former m4_token_data structure to
7786 m4_symbol. This change turned out to be a pig to get right, since
7787 the original code didn't need to modify the value cell itself,
7788 since changing the chain happened inside the m4_symbol that used
7789 to be returned -- I had to pass the address of the value cell
7790 across various function calls, incase the head value changed. I
7791 also tightened up the memory management to help me find a nasty
7792 memory corruption bug that took me all night to track down...
7794 * m4/m4private.h (struct m4_symbol): Removed.
7795 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7797 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7798 value cell. Updated all callers.
7799 * m4/symtab.c: Took advantage of the simplification in the data
7800 structures to rewrite a lot of this file more simply. There is
7801 still some room for optimisation here, but we should tackle that
7802 systematically closer to the release.
7804 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7805 revealed. This version is ahead of CVS libtool until I get chance
7806 to flush my changes.
7807 * m4/module.c (m4_module_remove): New function that holds the core
7808 of the old m4_module_unload.
7809 (m4_module_unload): Use it.
7810 (m4_module_unload_all): When we know the modules will never be
7811 used again (i.e. on exit), free up as much module memory as
7812 possible. There are still some artifacts from resident modules
7813 living inside ltdl.c, but everything else is freed.
7814 * m4/debug.c (m4_debug_exit): Free memory allocated in
7816 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7817 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7818 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7819 * m4/m4module.h: Updated prototypes.
7820 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7821 * m4/hash.h: Updated prototypes.
7822 * src/main.c (main): Use all these new functions to clean up as
7823 much memory as possible before exit.
7825 2001-09-18 Gary V. Vaughan <gary@gnu.org>
7827 The `traced' flag needs to be attached to the definition of a
7828 symbol rather than the current symbol containing the definition.
7829 Implementing this showed up some long standing post 1.4 bugs in
7830 flag propogation which I also fixed.
7832 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
7833 (struct m4_token_data): And add it back in here.
7834 * m4/input.c (init_macro_token): Propogate the traced flag
7836 * m4/macro.c (expand_argument): Ditto.
7837 * tests/builtins.at (trace2, trace3): New tests based on Akim's
7840 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7842 * m4/m4private.h (struct m4_token_data): Simplified by removing
7843 the redundant `traced' flag, and one level of structure nesting.
7844 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
7845 * m4/input.c (init_macro_token): No need to initialise removed
7847 * m4/macro.c (expand_argument): No need to copy it either.
7848 * m4/utility.c (m4_token_data_func_traced): Or provide an access
7851 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
7852 dependant on multiple symbols with the same key, so preserving
7853 relative symbol order in each bucket during resizing is no longer
7854 required. The resize function is considerably faster as a result.
7856 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
7857 s/m4_symbol_insert/m4_symbol_define/g;
7858 s/m4_builtin_insert/m4_builtin_define/g;
7859 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
7861 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7863 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
7864 commits, the m4_lookup_symbol dispatch function is split into
7865 specialised functions that must be called directly.
7867 * m4/m4module.h (m4_symbol_lookup_t): Removed.
7868 * m4/symtab.c (m4_lookup_symbol): Removed.
7869 (m4_symbol_builtin, m4_symbol_macro): New functions.
7870 * m4/builtin.c (m4_builtin_define): Split into...
7871 (m4_builtin_pushdef, m4_builtin_insert): ...these.
7872 (m4_macro_define): Split into...
7873 (m4_macro_pushdef, m4_macro_insert): ...these.
7874 * src/main.c (main): Set command line macros from `-D' parameters
7875 using `m4_macro_define'.
7877 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7879 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
7880 this from m4_remove_table_reference_symbols().
7881 * m4/m4module.h, m4/module.c: Updated all references.
7883 2001-09-07 Akim Demaille <akim@epita.fr>
7885 * modules/stdlib.c, modules/times.c: Misc cleanups.
7887 2001-09-07 Akim Demaille <akim@epita.fr>
7889 * configure.in: We now need Autoconf 2.52e.
7890 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
7891 and `M4_SYMBOL_DELETE'.
7892 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
7893 * src/main.c (main): Adjust.
7895 2001-09-06 Gary V. Vaughan <gary@gnu.org>
7897 Fix the obstack.h problem once and for all! At configure time we
7898 can test for a system supplied obstack.h: depending on the
7899 result, we now generate system.h with an #include of the correct
7900 header. As a bonus, I've also added a --with-included-obstack,
7901 incase the user doesn't like the system obstack for some
7902 reason... and also we can test the shipped obstack on a system
7903 that has oe of its own. We also now need to be careful to add
7904 build directories to the include search path, since the generated
7905 system.h will be in the build tree.
7907 * configure.in (AC_CONFIG_FILES): Generate system.h from
7909 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
7910 include the system obstack header or the copy shipped with M4.
7911 Allow the user to override configure and force the build to use
7912 the shipped version.
7913 * m4/system-h.in: New file, template for...
7914 * m4/system.h: ...this. Now deleted.
7915 * m4/m4module.h: Include system.h before everything else.
7916 * src/freeze.c: Ditto.
7917 * m4/Makefile.am (dist-hook): Remove generated system.h.
7918 (INCLUDES): Check builddir for generated headers before checking
7920 * modules/Makefile.am (INCLUDES): Ditto.
7921 * src/Makefile.am (INCLUDES): Ditto.
7923 2001-09-05 Gary V. Vaughan <gary@gnu.org>
7925 * TODO: Remove the items that have been addressed already.
7927 2001-09-05 Akim Demaille <akim@epita.fr>
7929 * src/main.c (main): Standardize --version.
7931 2001-09-05 Akim Demaille <akim@epita.fr>
7933 * modules/format.c (format): Have a bigger `str'.
7935 2001-09-05 Akim Demaille <akim@epita.fr>
7937 Rationalize warnings, reporting the macro name as if it were a
7938 program name, and assertions.
7940 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
7942 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
7944 Use assert for internal errors.
7945 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
7947 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
7949 * tests/builtins.at (pushpop): Adjust.
7951 2001-09-05 Akim Demaille <akim@epita.fr>
7953 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
7956 2001-09-05 Akim Demaille <akim@epita.fr>
7958 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
7959 * m4/macro.c, m4/symtab.c: Adjust.
7961 2001-09-05 Akim Demaille <akim@epita.fr>
7963 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
7964 (m4_symbol_pop, m4_symbol_del): this.
7965 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
7966 (m4_symbol_popdef, m4_symbol_delete): New.
7967 (m4_lookup_symbol): Adjust.
7968 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
7970 2001-09-05 Akim Demaille <akim@epita.fr>
7972 * m4/m4module.h (m4_symbol_lookup): Rename as...
7973 (m4_symbol_lookup_t): this.
7975 2001-09-05 Akim Demaille <akim@epita.fr>
7977 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
7979 * m4/symtab.c (m4_lookup_symbol): Adjust.
7981 2001-09-03 Gary V. Vaughan <gary@gnu.org>
7983 Bootstrap will now work with Libtool 1.4.1 or higher:
7984 * bootstrap: Remove stale autom4te.cache files when
7986 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
7988 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
7989 libtool.m4 directly.
7990 Run libtoolize to refresh ltmain.sh.
7991 * config/ltmain.sh: Deleted.
7992 * acinclude.m4: Deleted.
7993 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
7995 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
7996 implementation for the cvs impaired libtool user.
7998 2001-09-03 Akim Demaille <akim@epita.fr>
8000 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
8002 Avoid using `default' in switch, as it hides useful compiler
8003 warnings when a case is forgotten.
8005 2001-09-03 Akim Demaille <akim@epita.fr>
8007 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8008 is no such thing as `WITH_MODULES'.
8010 2001-09-03 Akim Demaille <akim@epita.fr>
8012 Improve the test suite's selfcontainedness.
8014 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8015 (Include, Undivert): Tag the other input files.
8016 * tests/generate.awk: Catch `@comment file:'.
8017 `-I $src' is no longer needed.
8018 `next' is really like `return': the rest is skipped.
8019 Adjust to `input.m4'.
8020 (fatal): New function.
8021 * tests/foo, tests/incl.m4: Remove.
8023 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8025 The shadowing mechanism and, infact, the whole symbol table
8026 implementation was creaking under the weight of the features piled
8027 on top of it. We now have a separate hash table module which will
8028 dynamically resize to keep symbol density withing good performace
8029 limits, and a new symtab module layered above it. Symbol lookups
8030 are now marginally more efficient (since the shadowed flag is no
8031 longer required) and symbol removal, such as on module unload, is
8032 considerably faster due to a reorganisation of the data structures
8035 * src/main.c (main): Don't mention `-H'.
8036 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8039 * m4/hash.c: New generalised dynamic hash table data structure
8041 * m4/hash.h: Public interface.
8042 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8043 (libm4_la_SOURCES): Add hash.c.
8044 * m4/symtab.c: More or less rewritten from scratch, within the
8045 bounds of the previous API.
8046 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8047 call. Updated all callers.
8048 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8049 declarations to reflect API changes.
8050 (M4INIT): Generate a declaration too, to avoid the warning with
8051 --enable-debug builds.
8054 * m4/utility.c (hash_table_size): Removed.
8055 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8056 names, which are then looked up by builtin_dumpdef() as necessary.
8057 This implies a small speedup in builtin_symbols(), which discarded
8058 all of the symbol info under the old call.
8059 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8060 shadowing is implicit in respect to the new data structures.
8061 symbol names are no longer duplicated here, they are stored in the
8062 key field of the hash table.
8063 Moved macro_args and blind_no_args...
8064 (m4_token_data): ...to here.
8065 m4/macro.c (expand_macro): Added a name argument since the symbol
8066 name is no longer copied into each struct m4_symbol. Modified all
8068 (collect_arguments): Ditto.
8069 * modules/m4.c (set_trace): Ditto.
8070 * modules/gnu.c (builtin_symbols): Updated.
8071 * src/freeze.c (produce_symbol_dump): Much improved in light of
8072 the improved symbol table layout.
8074 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8076 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8078 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8079 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8080 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8081 SYMBOL_HANDLE): Ditto.
8082 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8083 modules/gnu.c, modules/m4.c, src/freeze.c,
8084 src/main.c: Updated all references.
8086 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8087 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8088 already listed in m4_LDADD... how did that ever used to work?
8089 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8091 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8092 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8094 * tests/m4: Don't call the m4 wrapper script with libtool, it
8095 works fine all by itself.
8097 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8099 The experimental `changeword' feature never took off, and has
8100 no obvious advantages over `changesyntax' to compensate the
8101 enormous speed penalty it carries:
8102 * configure.in (ENABLE_CHANGEWORD): Removed.
8103 * m4/m4module.h (m4_set_word_regexp): Removed.
8104 * m4/m4private.h (m4_token_data): Removed original_text field.
8105 * m4/utility.c (m4_token_data_orig_text): Removed.
8106 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8107 * m4/macro.c: Ditto.
8108 * src/main.c: Ditto.
8109 * modules/Makefile.am (changeword.la): Removed.
8110 * modules/changeword.c: File removed.
8111 * doc/m4.texinfo: References to changeword and --word-regexp
8113 * po/POTFILES.in: modules/changeword.c removed.
8114 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8115 * tests/builtins.at (changeword): Test removed.
8117 2001-08-30 Akim Demaille <akim@epita.fr>
8119 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8120 This also help having a single list of m4 files: in
8122 * config/Makefile.am (STANDARD_MACROS): Rename as...
8123 (ACLOCAL_MACROS): this.
8124 (list-standard-macros): Remove.
8127 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8129 In an attempt to moderate my egomania...
8130 * tests/modules.at: Remove attributions.
8132 * tests/generate.awk: When making substitutions to "@&t@", either
8133 "&" or "\&" in the substitution string argument to gsub refer back
8134 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8137 2001-08-29 Akim Demaille <akim@epita.fr>
8139 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8140 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8141 (sync-lines, trace, translit, undivert, wrap): Move to...
8142 * tests/builtins.at: this new file.
8143 * tests/others.at (Discard comments, import-environment): Move to...
8144 * tests/options.at: this new file.
8146 2001-08-29 Akim Demaille <akim@epita.fr>
8148 * tests/others.at (Freezing modules)
8149 (--module-directory: absolute path, modpath2, modpath3)
8150 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8151 * tests/modules.at: here, new file.
8152 * tests/others.at, tests/generate.awk: Add a banner.
8153 * tests/testsuite.at: Adjust.
8154 (AT_CHECK_M4_FILTER): New, but unused.
8156 2001-08-29 Akim Demaille <akim@epita.fr>
8158 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8160 * tests/others.at (wrap): Inline wrap.m4.
8161 (shadow): Inline shadow.m4.
8162 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8163 * tests/m4: Simplify.
8165 2001-08-29 Akim Demaille <akim@epita.fr>
8167 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8170 2001-08-29 Akim Demaille <akim@epita.fr>
8172 * tests/generate.awk (normalize): s/@__@/@&t@/.
8174 2001-08-28 Akim Demaille <akim@epita.fr>
8176 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8178 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8180 * bootstrap (generate.awk): Generate test cases with new script.
8182 2001-08-27 Akim Demaille <akim@epita.fr>
8184 * tests/Makefile.am (installcheck-local): Don't use
8185 `dc_install_base' which is not visible here, but `exec_prefix'
8186 which is clearly the RT anyway.
8187 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8188 related to testing a now installed m4.
8189 * tests/m4: Do it here.
8191 2001-08-27 Akim Demaille <akim@epita.fr>
8193 * tests/others.at (indir): Formatting change.
8195 2001-08-27 Akim Demaille <akim@epita.fr>
8197 * tests/Makefile.am (installcheck-local): New.
8198 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8200 Prefer options over envvars.
8201 * src/main.c (main): First bug caught by the test suite (yeah!):
8202 --batch lacked a `break' which resulted in an accidental
8203 invocation of --discard-comments.
8205 2001-08-27 Akim Demaille <akim@epita.fr>
8207 * tests/others.at (capitalize, changeword, comments, ddivert)
8208 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8209 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8210 (sysv-args, trace, translit, undivert): Don't rely on files in
8211 examples/: AT_DATA them.
8213 2001-08-27 Akim Demaille <akim@epita.fr>
8215 Let the test suite use a wrapper around the not installed m4 to
8216 pretend it is (installed).
8218 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8219 such a way that m4 does not process them.
8220 * configure.in: The package name seems to be `m4', not `M4'.
8222 * tests/atlocal.in (at_package, M4): Remove.
8223 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
8225 2001-08-27 Akim Demaille <akim@epita.fr>
8227 * tests/Makefile.am (CLEANFILES): Remove.
8228 (DISTCLEANFILES, clean-local): New.
8229 * examples/mktests.sh: Remove.
8231 2001-08-27 Akim Demaille <akim@epita.fr>
8233 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8234 Don't use aclocal: it's written by hand.
8235 * aclocal.m4: m4_include all the files instead of being built by
8237 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8238 until it reads the traces by itself.
8239 * configure.in: Require Autoconf 2.42c as we are now using
8240 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8241 Catch unexpanded `jm_' macros.
8242 * config/atconfig.m4: Remove.
8243 * config/error.m4: new.
8244 * config/Makefile.am: Ship the files included by aclocal.m4.
8245 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8246 (TESTSUITE_AT): this, to please Automake.
8247 (TESTSUITE): This target uses autotest/autotest.m4, not
8248 autotest/general.m4.
8249 * tests/testsuite.at: Prereq Autotest 2.52c.
8250 * examples/Makefile.am (pkgdata_DATA): Rename as...

8253 (dist_man_mans): this.
8255 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8257 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8258 Robert Collins, building on Cygwin no longer requires Windows
8259 import and export symbol decorations.
8260 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8261 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

8268 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8269 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
8271 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
8272 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8274 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8276 Ansify the source. Previously we had a mix, where my code was
8277 in a K&R compatible style, and the preexisting code was in ANSI
8278 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8279 and now the code base is much cleaner.
8281 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8282 VOID macro and all users.
8283 * m4/m4module.h: Ansify function prototypes and headers.
8284 * m4/builtin.c: Ditto.
8285 * m4/evalparse.c: Ditto.
8286 * m4/input.c: Ditto.

8322 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8323 * modules/m4.c (undivert): Disable the possibility of undiverting
8324 several files at once: it is not documented, it is inconsistent
8325 with the other macros, it can be straightforwardly mocked by
8326 several invocations, and most importantly, it prevents the
8327 possibility of other kinds of extension.
8328 Use `m4_numeric_arg'.

8490 Drop Autoconf 2.13 compatibility.
8492 * configure.in (changeword): No need to undefine it, as anyway if
8493 it's defined, M4sugar moved it as m4_changeword.

8551 (M4FINISH_HANDLER): And similarly for finish functions.
8552 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8553 -- Add indirection to the CONC macro so that arguments are

8568 instead of the old module argument.
8569 (m4_builtin_table_install): Ditto.
8570 * modules/load.c (m4_resident_module): Removed. This is no

8591 module association does not belong with the symbol...
8592 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

8612 * tests/gethem: Use them.
8614 2001-08-14 Gary V. Vaughan <gary@gnu.org>

8631 shell variable m4_cv_func_obstack_h.

8633 script and m4 binary by using $srcdir.

8645 interactive mode off.

8714 feature to mark modules as resident if they export
8715 `m4_resident_module' as TRUE.

8782 Move the implementation of GMP support for the mpeval() builtin
8783 into a loadable module that depends on libgmp. mpeval() and
8784 eval() share a common parser, now in m4/evalparser.c; the code
8785 in m4/numb.c and m4/numb.h is now physically split between
8786 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8787 mpeval() backend), rather than being differentiated by cpp
8788 macros and multiple inclusion. The mpeval module is always
8789 built but will generate an diagnostic if it is used from an
8790 installation that didn't link in the gmp library.
8791 * modules/Makefile.am: build and install the new mpeval module.
8792 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8793 and m4/numb.h that are required for gmp support in mpeval().
8794 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8795 * m4/evalmp.c: Removed.
8796 * m4/m4module.h: Removed conditional prototype for
8798 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8799 and m4/numb.h that do not rely on gmp.
8800 * m4/evalparse.c: New file, contains the shared parts of the
8801 eval() and evalmp() parser implementations, and is no longer
8802 unencumbered by cpp magic to uncover the right parts.
8803 * m4/numb.h: Removed. It's former contents are split between
8804 m4/eval.c and modules/mpeval.c.
8807 * tests/other-tests/changeword.test: New test. Rudimentary
8808 testing of changeword builtin runs only if --wnable-changeword
8809 was used at configure time.
8810 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8811 alternation correctly. Split into two expressions to compensate.
8812 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
8813 * modules/Makefile.am: Build changeword module.
8814 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
8815 only when --enable-changeword was passed to configure.
8816 (builtin_changeword): If --enable-changeword was not used, then
8817 report that changeword() builtin has no support in m4 binary.
8819 2000-11-28 Gary V. Vaughan <gary@gnu.org>
8821 * src/main.c (main): Fixed a particularly nasty bug is
8822 user_search_path setting -- the -M flag processing must be
8823 extremely careful with search path ordering, or else the default
8824 installed module directory (possibly containing modules from a
8825 previous release) is placed earlier in the search path than any -M
8826 arguments (which are relied upon to load uninstalled modules with
8827 most of the tests in the regresion suite).
8829 * modules/load.c (builtin_load): Nasty hack to prevent adding
8830 symbols to symtab again if a module is loaded more than once.
8831 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
8833 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
8834 possible NULL pointer dereference.
8836 * m4/module.c (m4_module_find_by_modname): Renamed from
8837 m4_module_modname_find. Fixed all references.
8838 (m4_module_find_by_builtin): New function.
8840 * modules/modfreeze.test: load the `load' module with each
8842 * src/freeze.c (produce_frozen_state): Simplified in light of
8843 module field in m4_symbol. Allow a third argument for text macros
8844 to name the originating module.
8845 (reload_frozen_state): ditto.
8846 * m4/m4module.h: Fixup prototypes.
8847 * m4/builtin.h (m4_builtin_define): Add a module argument so
8848 that symbols can be registered against the defining module.
8849 (m4_macro_define): ditto.
8850 * m4/m4private.h (m4_symbol): Make the module field const to save
8851 on casting in the rest of the code.
8852 (SYMBOL_MODULE): New macro.
8854 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
8855 symbol reference maintenance bugs when removing a symbol from the
8858 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
8860 2000-11-27 Gary V. Vaughan <gary@gnu.org>
8862 * configure.in (m4_cv_func_obstack): A better check for whether
8863 libc has an obstack implementation.
8864 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
8866 * configure.in (--with-modules): Changed semantics. This
8867 option is now used to list modules to be preopened.
8868 * src/m4.h: #include "ltdl.h" unconditionally.
8869 * src/main.c: Removed all dependencies on WITH_MODULES.
8870 * src/freeze.c: ditto.
8871 * modules/Makefile.am: ditto.
8872 * m4/m4.c (builtin_m4exit): ditto.
8873 * modules/modpath1.test: ditto.

8878 * modules/shadow.test: ditto.
8879 * modules/unload.test: ditto.
8881 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
8882 comes up on demand in LTLIBOBJS now.
8883 * configure.in (getopt_long): Creating and relying on a link for
8884 getopt.h on hosts with no getopt_long() of thier own works
8885 correctly now. This is necessary so that callers of getopt_long()
8886 can simply `#include <getopt.h>': the naive way of doing this
8887 would end up using our own getopt.h and the installed
8888 getopt_long(), which is asking for trouble!
8889 (obstack_init): A similar argument applies to obstack.h and
8892 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
8893 On Solaris-2.5 (at least) the native dlopen implementation
8894 gets confused about m4.o when looking for module "m4". This
8895 version always looks for .la an .$lib_ext suffixed names first
8896 to work around the problem. Sigh.
8898 * po/POTFILES.in: Take account of these file movements.
8899 * src/Makefile.am (m4_SOURCES): removed eval.c.
8900 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
8901 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
8902 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
8903 * modules/m4.c (builtin_eval): Use m4_evaluate().
8904 * m4/eval.c: Moved here from src/eval.c to facilitate
8905 implementation of eval() builtin as part of the `m4' loadable
8907 (m4_evaluate): renamed from evaluate for namespace cleanliness.
8908 * m4/numb.c: Moved here from src/numb.c, since it is #included
8909 into eval.c at compile time.
8910 * m4/m4module.h (m4_evaluate): Added prototype.
8911 * src/m4.h (evaluate): Removed prototype.
8913 2000-11-25 Gary V. Vaughan <gary@gnu.org>
8915 * modules/perl.c (builtin_perleval): Use PL_na for
8916 compatibility with perl-5.6.
8918 * src/main.c (main): It is now safe to
8919 ``m4_module_install("m4")'', without tripping over the m4
8921 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
8922 versions having fixed the insidious module search order bug.
8924 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
8925 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
8927 * configure.in: Figure out whether to use the installed
8928 getopt.h or the supplied one.
8929 * src/Makefile.am: ditto.
8931 * po/POTFILES.in: List files in their new positions.
8933 * config/ltmain.sh: This needs to be checked in to match the
8934 libtool macros copied to acinclude.m4 (until a released
8935 libtool copes with m4's needs).
8936 * bootstrap: Run gettextize.
8938 2000-11-24 Gary V. Vaughan <gary@gnu.org>
8940 * AUTHORS: Added my details.
8943 * bootstrap: temporary update until released libtool catches up.
8945 * All files: Use new GNU GPL copyright blurb with current contact

8979 * modules/gnu.c: New file implementing a new loadable module wuth
8980 definitions for all the gnu extension builtins.
8981 * modules/format.c: Moved here from src/format.c. Now included
8984 * src/main.c (main): Load the traditional module if m4 was
8985 started in `no_gnu_extensions' mode.
8986 * modules/traditional.c: New file implementing the ``unix'' macro,
8987 required when m4 is executed in traditional mode, as a loadable
8990 * src/main.c: Renamed from m4.c to avoid confusion with
8992 (main): Always load the m4 module.

9012 directory to facilitate builtin migration.
9014 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9016 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9017 error message, to make translators' jobs a little easier.

9019 (builtin_traceon): ditto.
9020 (builtin_traceoff): ditto.
9021 Reported by Akim Demaille <akim@epita.fr>

9024 pkgincludedir instead.

9047 makeinfo calculates them for us, and to make any future
9048 reorganisation easier.
9049 (Frozen files): Document format version 2.
9050 `V' now takes argument `2'.
9051 `F' can take a single argument if symbol and builtin names
9052 are the same, or 3 arguments if the builtin is from a module.
9053 New `S' specification for saving syntax table contents.

9190 * src/m4.c (main): Assume interactive mode if STDIN is connected
9192 Changed startup sequence slightly so that syntax is not
9193 initialised from here when loading a frozen file.
9195 * src/builtin.c: Much improved macro definition style.
9196 * src/m4private.h: Internal structures for m4_builtin and

9203 external definition.

9208 odule defines an identical name.
9209 * src/symtab.c (remove_table_reference_symbols): remove all symbol
9210 table entries which refer to a given builtin table.

9235 before calling lt_dlinit!, fix warnings
9237 2000-01-18 Gary V. Vaughan <gary@gnu.org>

9265 increment serial number.
9267 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
9268 src dir and immediately after libm4 is built for confidence that
9269 it doesn't rely on the src directory.

9271 makeinfo stop the build on cygwin (because they don't work).
9273 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9275 * m4/m4private.h: ...is not a public header, so moved to src.

9292 * src/output.c: ditto.
9293 * src/path.c: ditto.
9294 * stackovf.c: ditto.
9297 * po/POTFILES.in: compensate for renaming of lib/*.
9298 * m4/Makefile.am (CLEANFILES): @EXEEXT@ left libtool wrapper behind.
9299 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
9300 and then in $(top_srcdir)/lib (for eg. "m4private.h").
9301 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
9303 * m4/m4error.h: Renamed error.h, for installation to
9304 $prefix/include/m4..
9305 * m4/m4obstack.h: Renamed obstack.h, for same reason.
9306 * m4/m4regex.h: Renamed regex.h, for same reason.
9307 * m4/m4error.c: Renamed error.c, and use #include "error.h".

9309 * m4/m4regex.c: Renamed regex.c, and fix #includes.
9311 * lib: moved to m4 to easily support header installation to

9319 From Akim Demaille <akim@epita.fr>
9321 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9323 * src/ltdl.c: Use access() to abort doomed module load attempts
9324 if module file does not exist.
9326 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9327 getopt1.o will already be used if appropriate, so I moved getopt.c
9328 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9330 * modules/modpath1.test: Use correct filename in header line.
9331 * modules/modpath2.test: ditto.
9332 * modules/modpath3.test: ditto.
9333 * modules/modpath4.test: ditto.
9335 Without these changes lt_dlopen("test") attempts to
9336 LoadLibrary("/bin/test") on Windows, which although harmless
9337 generates a spurious error message which spoils most of the tests:
9338 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9339 (TESTS): s/test.test /modtest.test /
9340 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
9341 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
9342 * modules/modpath1.test: s/test.m4 /modtest.m4 /
9343 * modules/modpath2.test: ditto.
9344 * modules/modpath4.test: ditto.
9345 * modules/modpath3.test: s/-m test /-m modtest /
9346 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9348 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9350 * src/ltdl.c (find_file): Updated to new version with fixed memory
9351 allocation bug in `next'.
9352 * src/ltdl.h: updated to match.
9354 * modules/Makefile.am: Cleaned up and reordered.
9356 2000-01-16 René Seindal <rene@seindal.dk>
9358 * modules/Makefile.am (TESTS): New tests for the module system.
9360 * modules/*.test: New files.
9362 * src/m4.c (main): Added call to module_init().
9363 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9365 * src/m4.h: Added declaration of module_init().
9367 * src/module.c (module_init): No longer static
9369 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9370 Added to shut up automake about non standard libtool library
9373 * src/module.c: Disabled DEBUG by default.
9375 * modules/README: Changed example from unload.m4 to shadow.m4
9377 * modules/shadow.m4: Renamed from unload.m4
9379 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9381 * src/m4.c (main): Functionality for -m and -M were reversed.
9384 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9386 * doc/help2man.pl: updated to version 1.020.
9388 * lib/COPYING.LIB: updated to version 2.1.
9390 * lib/m4module.h: restructure the M4_SCOPE code to work when
9391 creating a dll which links with libm4.la and both DLL_EXPORT
9392 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9395 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9397 Merged the following changes from my tree:
9399 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9401 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9402 ported to compile shared libs.
9404 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9405 use `__declspec(dllimport)' when linking libm4.la on win32.
9406 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9408 * configure.in (M4OBJS): Discover whether we need the shipped
9409 implementation of getopt_long.
9410 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9411 main binary here, as opposed to the module library in lib/libm4.la.
9413 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9415 * modules/README: Updated to describe the improved libltdl based
9417 * README (cygwin): Added some compilation notes for building m4
9418 correctly under cygwin.
9419 * TODO: Cleaned out the entries for the module system since they
9420 are now implemented.
9422 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9423 all instances of __P with M4_PARAMS.
9425 * lib/getdate.h: removed unreferenced file.
9427 * lib/m4private.h: New file to define the private interface to the
9428 token_data struct, which must be shared between m4module.c, and
9429 builtin.c but not exported to modules built from the installed
9430 m4module.h since it's size changes depending on compile time
9433 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9435 * lib/m4module.h: New file to define the interface available when
9436 compiling m4 modules.
9437 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9438 necessary for module compilation into this new file.
9440 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9441 avoid nameclash with other system headers) necessary for compiling
9443 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9444 so that modules can include the (renamed) installed headers and
9445 be guaranteed a matching implementation.
9446 * lib/m4error.h: renamed from error.h.
9447 * lib/m4obstack.h: renamed from obstack.h.
9448 * lib/m4regex.h: renamed from regex.h.
9449 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9450 implementation, simply include the shipped version
9451 unconditionally, otherwise it is hard for a module to know
9452 whether the m4obstack.h header it is using matches the
9453 implementation it ends up linking against.
9454 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9457 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9459 * examples/misc.test: Don't run this test on machines which don't
9460 have a root user in /etc/passwd (e.g. cygwin).
9462 * tests/get-them (/^@example$/): Error messages might have a
9463 ``.exe'' suffix to the program name, or else use the libtool
9464 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9465 of these cases are now catered for when comparing error messages
9467 * tests/other-tests/*.test: ditto.
9468 * examples/*.test: ditto.
9470 * tests/defs (M4): use libtool execute mode.
9471 * examples/defs (M4): ditto.
9473 * tests/get-them (END): explicitly close any open file.
9474 (printthem): In a regular expression, '{' is the start of a repeat
9475 count! Use `[{]' for a literal open brace.
9476 (/^@node /): Don't use substr on a string shorter than the trim
9479 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9481 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9483 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9485 2000-01-10 Andreas Schwab <schwab@suse.de>
9487 * tests/other-tests/gmp.test: Find config.sh in build directory.
9489 * configure.in: Find tests/mkconfig.sh in $srcdir.
9491 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9492 <signal.h> (for SUS2 compliant systems).
9494 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9497 2000-01-10 René Seindal <rene@seindal.dk>
9501 * TODO, NEWS: Cleaned up and updated.
9503 * src/m4.c (main): New variable exit_status for exit status in
9504 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9505 file cannot be read instead of EXIT_SUCCESS.
9507 * src/builtin.c (m4_indir): Changed error message to help
9508 translators (from Akim Demaille <demaille@inf.enst.fr>).
9510 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9513 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9516 * src/input.c (match_input): Reordering of code, to avoid multiple
9517 calls to push_string_init() from obstack_grow(), which can happen
9518 with some compilers (found and fixed by James Bonfield
9519 <jkb@mrc-lmb.cam.ac.uk>).
9521 * src/stackovf.c: Added prototypes for ultrix.
9522 (setup_stackovf_trap): Added __P to cast.
9523 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9525 2000-01-09 René Seindal <rene@seindal.dk>
9527 * doc/m4.texinfo (Changequote): Added comment about changing
9528 quotes when the old quote is a part of the new.
9530 * src/builtin.c (expand_ranges): Added break after trailing dash.
9531 This caused misbehavious on some systems (found and fixed by Akim
9532 Demaille <demaille@inf.enst.fr>).
9534 * AUTHORS: Thomas Tanner included
9536 * acconfig.h: Added entry for ss_sp (see below).
9538 * configure.in (use_stackovf): Added check for stack_t with member
9539 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9540 <eggert@twinsun.com>).
9542 * doc/m4.texinfo (Frozen files): Added a simpler example for
9543 generating frozen files from several input files.
9545 1999-11-14 Paul Eggert <eggert@twinsun.com>
9547 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
9548 lib/regex.c, lib/xmalloc.c.
9550 1999-11-10 René Seindal <rene@seindal.dk>
9552 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9554 * src/module.c: reindented.
9555 (module_load): return if this is a repeated load of same module.
9556 (module_init): slight change of logic to avoid repeated
9557 initialisation debug messages.
9559 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
9560 in the distribution.
9562 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9563 automake warnings about missing lib prefix.
9564 (time_la_LDFLAGS): ditto
9565 (stdlib_la_LDFLAGS): ditto
9567 1999-11-10 Paul Eggert <eggert@twinsun.com>
9569 * src/m4.h: Include error.h, since our macros use error.
9570 * src/m4.c: Don't need to include error.h.
9572 1999-11-09 Paul Eggert <eggert@twinsun.com>
9574 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9575 and zero, as Solaris 7 cc does.
9576 (bcopy): Remove macro; no longer needed with new obstack.h.
9578 * src/output.c (freeze_diversions): Don't assume that a
9579 diversion size can fit in `int'. Check for diversion file
9580 size too large to be printed with `unsigned long'.
9582 * src/Makefile.am (CFLAGS): Omit -Wall.
9584 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
9586 * src/debug.c (trace_format):
9587 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
9589 * src/freeze.c (produce_frozen_state):

9607 (ALL_LINGUAS): Added Czech translation (cs).
9609 1999-03-30 Gary V. Vaughan <gary@gnu.org>
9611 * src/builtin.c: moved module loading functions into...
9612 * src/module.c: entirely new implementation using libltdl.
9613 * po/POTFILES.in: added src/module.c.
9614 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
9615 are modules, not linktime libraries.
9616 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
9617 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9618 avoidance on exported symbols.
9619 * modules/test.c (m4_macro_table, m4_init_module,
9620 m4_finish_module): ditto.
9621 * modules/time.c (m4_macro_table): ditto.
9623 * modules/time2.m4: new file which requires command line loading
9625 * src/m4.c (--load-module): dynamically load named runtime module
9626 into running executable before reading the source.
9627 (--module-directory): prepend a directory to the module search
9629 (module_init()): Do this the first time we load a module instead;
9630 if the module subsystem is broken normal m4 scripts can still run.
9631 * src/m4.h (install_builtin_table): is now exported.
9633 1999-03-26 Gary V. Vaughan <gary@gnu.org>
9635 * src/module.c: removed. No longer required.

9645 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
9646 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9647 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9649 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9651 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9652 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9653 the installed gettext.m4 file when running aclocal.
9655 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9657 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9658 distinguish this from the last prerelease.
9659 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9660 in its own subdirectory.
9662 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9663 lib prefix on a module" feature.
9664 (LDFLAGS): Added `-module -avoid-version' flags to build
9665 versionless module libraries.
9666 * src/builtin.c (m4_load_module): use libltdl.
9667 (module_unload_all): use libltdl.
9668 * src/m4.c (module_init): initialise module loading on demand for
9669 better diagnostics, and so that m4 will still work even if
9670 the module code is broken.
9671 * src/m4.h (module_init): removed. No longer relevant.
9672 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9673 exported symbols for compatibility with dlpreopening.
9674 * modules/test.c (m4_macro_table, m4_init_module,
9675 m4_finish_module): ditto.
9676 * modules/time.c (m4_macro_table): ditto.
9678 * bootstrap: New file. Runs all the autoutils in the right order
9679 after a fresh checkout, or a make maintainer-clean.
9681 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9683 * src/builtin.c (dump_symbols): New function, factoring common
9684 content of m4_dumpdef and m4_symbols.
9685 (m4_dumpdef): Use it.
9686 (m4_symbols): New function, implementing `symbols'. Use it.
9687 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9688 file compile with modern makeinfo.
9689 (Symbols): New node, documenting symbols.
9690 (direntry): Modernize.
9692 1998-12-11 René Seindal <rene@seindal.dk>
9694 * src/builtin.c (predefined_tab): New predefined macros
9695 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9696 configure time options.
9698 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9700 * src/module.c (module_try_load): Don't try to be clever and
9701 overwrite argument string. Instead allocate all constructed
9702 strings locally, since they can have arbitrary lengths. Make
9703 arguments pointers to const.
9704 (module_search): Simplify due to above change.
9706 1998-11-29 René Seindal <rene@seindal.dk>
9710 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
9712 * tests/other-tests/import-environment.{m4,test}: New test.
9714 * tests/other-tests/discard-comments.{m4,test}: New test.
9716 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
9718 * src/m4.c (main): New option -c --discard-comments.
9719 New global variable discard_comments.
9721 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
9722 discarded, ie never returned from next_token().
9723 Added declaration of discard_comments.
9725 * src/input.c (next_token): Now loops until token type is not
9726 TOKEN_NONE. Comments are now given this type when comments should
9729 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
9732 1998-11-28 René Seindal <rene@seindal.dk>
9734 * src/m4.c (main): New option --import-environment (no single
9737 * When configured with --with-gmp both the normal (fast) eval()
9738 and the gmp aware mpeval() are defined. To restore previous
9739 bahaviour use "define(`eval', defn(`mpeval'))".
9741 * tests/other-tests/gmp.m4: Changed to use mpeval().
9743 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9744 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9746 * src/eval.c: Now includes "numb.c" directly. Everything in this
9747 file must by static, except evaluate(), which is changed to
9748 mp_evaluate() if USE_GMP in force.
9750 * src/numb.c: Changed to be included by eval.c instead of being
9751 compiled separately. Everything is declared static.
9753 * src/numb.h: Removed declarations of functions, as numb.c is now
9756 * src/builtin.c: Declaration of m4_mpeval() added.
9757 Inserted `mpeval' in builtin table.
9758 (do_eval): New function with common code for m4_eval and m4_mpeval.
9759 (m4_mpeval): New function for gmp version of eval.
9761 * src/m4.h: Declaration of mp_evaluate().
9763 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9764 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9766 * src/m4.c (main): m4 --version also shows which options were used
9767 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9769 1998-11-27 René Seindal <rene@seindal.dk>
9771 * Error messages now always print program name before input file
9772 name as specified by GNU coding standards. Reported by Akim
9773 Demaille <demaille@inf.enst.fr>.
9775 * doc/m4.texinfo (Include): Change due to changed error message
9779 * tests/get-them: Minor change to sed script due to changed error
9782 * src/m4.c (print_program_name): New func used to print program
9783 name, input file and line number in error (). Used as an
9784 error_print_progname handler.
9785 (reference_error): Removed.
9786 (main): Assigns error_print_progname.
9788 * src/m4.h (M4ERROR): Removed reference_error ().
9790 1998-11-25 René Seindal <rene@seindal.dk>
9792 * Updated to libtool 1.2b.
9794 * src/builtin.c (install_builtin_table): Added braces to avoid
9795 warning of ambiguous 'else'.
9797 * src/module.c: Inserted search path code from path.c modified to
9799 (module_init): Configured default path used only if M4MODPATH is
9801 (module_try_load): Now reads libMODULE.la as generated by libtool
9802 for actual module name.
9803 (module_load): Gives better error messages on failure.
9805 * src/m4.h: Added declarations of structures and functions for
9806 generic search path handling.
9808 * src/path.c: Removed all module specific code and introduced new
9809 functions of more generic search path handling.
9811 1998-11-24 René Seindal <rene@seindal.dk>
9813 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
9814 included gettext, as <libintl.h> might not be found
9815 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
9817 1998-11-22 René Seindal <rene@seindal.dk>
9819 * src/output.c (insert_diversion): Fixed bug that might cause m4
9820 to read from standard output! Triggered by input
9821 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
9822 so now 'undivert(0)' does nothing.
9824 1998-11-18 René Seindal <rene@seindal.dk>
9828 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
9829 could be changed when compiling a illegal regexp, causing later

9882 modules in pkglibexecdir.
9884 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
9885 These two are now initialised by autoconf macros.
9887 * src/path.c (module_env_init): MODULE_PATH is always on the
9890 * src/Makefile.am: Now generated pathconf.h which defined the
9891 default MODULE_PATH.

9897 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
9898 build and install automatically, and it is prepared for other
9899 interfacec than dlopen().
9901 * src/builtin.c (predefined_tab): Added __m4_version__ for the
9902 current version of GNU m4. It is a GNU extension.

9982 1998-10-07 René Seindal <rene@seindal.dk>
9986 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
9987 .test, as the files are no longer just m4 input.
9989 * tests/get-them (FILE): Changed .m4 extension to .test.
9991 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
9992 Otherwise quoted strings with leading whitespace first in a macro
9993 argument would be eliminated.
9995 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
9996 (expand_argument): Do.
9998 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

10000 character. Otherwise they might include a comment/quote leader.
10001 (next_token): Returns new token type TOKEN_SPACE.
10003 * src/builtin.c (push_builtin_table): New function to push a
10004 builtin_table on the stack without installing its contents.
10005 (find_builtin_by_name): Added call to push_builtin_table() if

10032 * src/builtin.h: New file, declares some functions from builtin.c
10033 that are of use for other modules (shipout_int, numeric_arg,
10034 skip_space, bad_argc), and the macros ARG() and DECLARE().
10036 * src/builtin.c (install_builtin_table): New function. Each
10037 module brings in a builtin_table, which is pushed on a stack.
10038 (struct builtin_table): New struct for list of builtin_tables.
10039 (m4_loadmodule): New function to implement builtin "loadmodule".

10049 include files and one for modules.
10051 * src/m4.h: Added declarations for new functions in module.c and
10054 * src/m4.c (main): Added call to module_init().

10064 <dlfcn.h> and -ldl.
10066 * acconfig.h: Added WITH_MODULES
10068 1998-10-02 René Seindal <rene@seindal.dk>
10070 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10071 check and variables TESTS. These tests are now run from the
10074 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10075 directory. The files stay there but the tests are run from the
10078 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10080 * tests/run-test: New file. Run a test manually
10082 * tests/Makefile.am, tests/get_them: Moved automatically generated
10083 tests (from the manual) to sub directory tests/gentest/. The
10084 tests/ directory had gotten a bit messy.
10086 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10088 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
10089 wrap}.test: Added a few testcases.
10091 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10095 * lib/Makefile.am (noinst_HEADERS): regex.h added
10097 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10098 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10100 * acm4/Makefile.am: created providing rules to create
10101 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10103 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10104 `C'. Reported by Ulrich Drepper.
10106 * Makefile.am (SUBDIRS): Removed checks directory
10107 * configure.in (AC_OUTPUT): Removed checks/Makefile
10109 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10110 the space when m4.texinfo is edited and whitespace.el is active.
10111 (Defn,example): idem.
10113 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10115 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10116 ../COPYING. ../Makefile is a file which is certainly present when
10117 test is executed in testSubDir. One can't be sure that the COPYING
10118 file is in .. or ../.. in all situations, the ../Makefile is
10121 * doc/m4.texinfo (Include): adjusted expected test output
10122 according to new tests, i.e. the input will always come from the
10123 file `in' created by the test.
10125 * tests/Makefile.am: Added three lines at the top to get
10126 esyscmd.1.test working.
10128 * tests/get-them: modified to generate clearer tests who will need
10129 less maintenance when new test examples are created in
10130 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10131 need the generic file `defs') shell scripts creating `in', `ok',
10132 `out' and when apropriate `okerr' and `err' in the directory
10133 `testSubDir' when executed. The compare of `ok' and `out'
10134 (and of `okerr' and `err') will be the exit status of the test.
10135 `out' must match `ok' (and `okerr' must match `err') for the test
10138 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10139 the tests generated by tests/get-them getting it input normally
10140 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10141 (dot) before the numeric part) is reserved for all other (hand
10142 written) tests. The `+' means one or more times.
10144 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10146 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10147 supported short man page to refer to info documentation

10173 * src/builtin.c (m4_changesyntax): Added builtin macro
10174 "changesyntax" to modify the syntax table.
10176 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
10177 table. All categories are assigned a syntax code and tokens are
10178 read according to this table.
10180 1998-08-09 René Seindal <rene@seindal.dk>
10182 * src/numb.{c,h}: New files, implements multiple precision eval
10183 using GNU gmp. Originally submitted by John Gerard Makecki
10184 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
10186 * doc/m4.texinfo (Eval): Added documentation for multiple
10187 precision arithmetic library support.
10189 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
10190 to accommodate multiple precision eval.
10192 1998-08-07 René Seindal <rene@seindal.dk>
10194 * src/input.c (MATCH, match_input), src/m4.h: changed definition
10195 of comment and quote strings to `unsigned int' to allow eight bit
10196 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
10198 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
10199 patch from Mike Howard <mike@clove.com>
10201 1998-08-06 René Seindal <rene@seindal.dk>
10203 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

10214 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
10216 * configure.in (ALL_LINGUAS): Added complete list of translations:
10217 de fr it ja nl ru sv.
10219 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10221 * po/nl.po: Dutch translation by Erick Branderhorst.
10223 * po/fr.po: French translation by Erick Branderhorst, based on the
10224 translations by François Pinard in fr.msg and m4.cod.
10226 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>

10240 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
10241 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:

10296 be opened, return immediately after producing the error message.
10297 Reported by Andreas Schwab.

10300 ANSIfying compiler flags, this is of no use to check it before.
10301 Reported by Alexander Lehmann.
10303 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
10305 * src/macro.c (collect_arguments): Cast obstack arguments to
10306 (voidstar), so avoiding compiler warnings.
10307 Reported by Joseph E. Sacco.
10309 * src/freeze.c (produce_frozen_state): Cast printed lengths to
10310 (int) so they correspond to %d format items.

10350 of $U, put underline in extensions rather than in basenames. Use
10351 implicit rules, now that regularity makes this possible.
10352 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
10353 of ansi2knr whenever it is needed.
10354 * configure.in: Adjusted for correct STACKOVF substitution.
10355 * src/debug.c (trace_format): When not __STDC__, use (...) as a

10424 (TAGS): Make in $(srcdir).
10426 * configure.in: Use `choke me' in test, like everywhere!
10428 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
10429 unreacheable and useless.
10431 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
10433 * lib/Makefile.in (DISTFILES): Distribute TAGS.
10434 (distclean): Do not remove TAGS.

10436 * Makefile.in: Make TAGS in lib also, not just in src.
10437 Reported by Karl Berry.
10439 * Makefile.in (distclean, realclean): Instead of recursively
10440 calling $(MAKE) for the -local part, allow parallel execution of
10441 -recursive and -local, only delay the removal of config.status,
10442 which is repeated in both goals.
10444 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
10448 * Makefile.in: Group all *clean-recursive goals in one, using sed
10449 to remove `-recursive' while calling make recursively. Also, use
10450 a subshell for each recursive $(MAKE).
10451 Reported by Jim Meyering.
10453 * src/m4.h (memcpy): Define with bcopy for BSD systems.
10454 Reported by Kaveh R. Ghazi.
10456 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
10457 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
10460 * configure.in: Use date instead of touch for stamp-h.
10461 * Makefile.in (stamp-h.in): Idem.
10463 * Makefile.in (distclean, realclean): Force serial execution of

10512 Reported by Jim Meyering.
10514 Solidify frozen files with respect to -P:
10515 * src/m4.c: Have -P set prefix_all_buitins variable instead of

10518 * src/builtin.c (builtin_init): Merge in functionality from
10519 previous prefix_all_buitins function, while making entries in the
10520 symbol table, but not modifying the builtin description itself.
10522 * src/freeze.c (reload_frozen_state): Add a useless `break;',
10523 because *many* compilers do not accept an empty `default:'.
10524 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
10525 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
10527 * configure.in: Use AC_TYPE_SIGNAL.

10532 m4 in the src directory.
10533 * Makefile.in (check): Don't.
10534 Reported by Akiko Matsushita and Jim Meyering.

10548 * Makefile.in: Adjusted.
10549 * configure.in: Configure new Makefiles.
10551 * m4.h: Declare STRING typedef. Use it for comment and quote
10552 strings, adjusting all references. (This is the rudiments of a
10553 beginning for the eventual withdrawal of NUL terminated strings.)
10554 * output.c (shipout_text): Accept a length parameter, and use it.
10555 All callers adjusted.
10557 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
10559 * m4.h: Include <unistd.h> if it exists.

10579 * output.c (freeze_diversions): New function.
10580 * m4.h: Declare freeze_diversions.
10581 * freeze.c: Document frozen file format, revise it, call

10583 reload them properly.
10584 * m4.c: Do not undivert automatically at end when status being
10585 frozen. Do not call builtin_init when reloading frozen state.
10587 Speed up diversion processing:
10588 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
10589 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
10590 structure and variables, cached variables out of output_diversion,
10591 reallocate_diversion_for and OUTPUT_CHARACTER.
10592 (shipout_text, make_diversion, insert_diversion): Adapted to new
10594 (insert_file): Use better buffering.

10602 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
10604 * symtab.c (hack_all_symbols): Use hash_table_size instead of
10605 constant HASHMAX, for -H option to work better.
10607 * builtin.c (DECLARE): Simplify by using _ ().
10609 * freeze.c: New file.
10610 * Makefile.in: Compile it, distribute it.
10611 * m4.c: Recognize, document and process --freeze-state (-F) and

10631 Reported by Akiko Matsushita.
10633 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
10635 * m4.h: Include <sys/types.h>.

10637 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
10639 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
10640 as size_t, not int.
10641 * builtin.c (dump_args): Declare len as size_t, not int.
10643 * debug.c: Prototype the forward declaration of debug_set_file.
10645 * builtin.c (m4_undivert): Replace div by file, for avoiding the
10646 shadowing of this variable.
10647 * output.c (insert_diversion): Idem.
10649 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
10650 (input_init): Duplicate default quote and comment strings.

10652 even default quote strings.
10653 (set_comment): Free previous comment strings in all cases.
10654 Duplicate even default comment strings.

10659 * m4.c (usage): Reorganize the --help output by topic. Include a
10660 description for debugging flags.
10662 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
10664 * configure.in: If sigaction is available and SA_ONSTACK defined,
10665 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
10666 defined, use sigvec. Else don't compile stackovf.c.
10667 * stackovf.c (setup_stackovf_trap): Idem.
10668 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
10671 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
10673 * m4.c (usage): Replace printf par fputs.
10675 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
10679 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
10681 * configure.in: Check for sigaction and sigvec. Add a new delayed
10682 check for RLIMIT_STACK, combine in the checking for getrlimit.
10683 All those things are not universally available.
10684 * stackovf.c: Split setting up the trap handler and catching
10685 signals, for better taking care of various configure outcomes.
10686 * examples/stackovf.sh: Correct a typo.
10687 Reported by Eric Backus, Jim Avera and Jim Meyering.
10689 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
10691 * ansi2knr.c: New version sent by its author, Peter Deutsch.
10693 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
10695 * Makefile.in: Modify so parallel make will not try making
10696 lib/libm4.a twice simultaneously.
10697 Reported by Jim Meyering.
10699 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
10701 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
10702 error message, for when no code possibility exists. Even if this
10703 line is completely #ifdef'ed out, it brings a syntax error.
10704 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
10706 * Makefile.in (install): Have install depend on all too, for lib
10707 to be remade as needed.
10709 * examples/stackovf.sh: Try ksh, bsh and bash for shells
10710 providing ulimit, instead of using only ksh.
10711 Reported by Jim Avera and Joseph E. Sacco.
10713 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
10715 * Makefile.in (check): Have it depend on all instead of m4. In
10716 this way, a change in lib will be detected and processed.
10718 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10719 instead of using sscanf which stops as soon as there is a
10720 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10721 and divert(1xyzzy) were all accepted without any warning or error
10723 * m4.h: Declare strtol as long if not including stdlib.h.
10724 * configure.in: Check for limits.h, and replace strtol if missing.
10725 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
10726 * lib/strtol.c: New file, from elsewhere.
10727 Reported by Andreas Schwab.
10729 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
10731 * macro.c (expand_macro): Cast value to (boolean) prior to
10732 assigning it to traced.
10733 Reported by Tom McConnell.
10735 * Makefile.in (m4): Always make all in lib first.
10736 Reported by Jim Meyering.
10738 1994-07-06 Jim Avera <jima@netcom.com>
10740 * stackovf.c: Isolated OS-dependent sections; Improved portability,
10741 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10742 handlers), and a default error message if the fault address is not
10743 available (when neither siginfo.h nor BSD sigcontext are supported).
10744 * configure.in: Changes for stackovf.h: Check for sigcontext,
10745 sigaction, sigstack, and define rlim_t as int if necessary.
10746 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10747 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10748 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10750 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10752 * configure.in: Use AC_SET_MAKE.
10753 * Makefile.in: Use @SET_MAKE@.
10754 Reported by Jim Meyering.
10756 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10757 Reported by Ian Taylor.
10759 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10761 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10762 because siginfo.h is unrelated to standard headers, and siginfo.h
10763 is already checked for.
10764 Reported by Joseph E. Sacco.
10766 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10768 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10771 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10773 * builtin.c (substitute): Use \& to represent this part of the
10774 string which was matched by the whole regexp, instead of
10775 representing the whole string. Any usage of \0 issues a warning
10776 and acts like \&, it will disappear in some subsequent release.
10778 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10780 * m4.c: Complete prototype for forwarded declaration of usage.
10782 * input.c (init_macro_token): Correct own reference in error
10783 message. Previous name get_macro_func was referred to instead.
10784 (next_char): Correct own reference in error message. Previous
10785 name advance_input was referred to instead.
10787 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10788 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10789 and_term, not_term, logical_not_term, cmp_term, shift_term,
10790 add_term, mult_term, exp_term, unary_term, simple_term): Add
10791 prototype to forwarded declarations. Declare parameter v1 as
10792 eval_t * instead of int *. Same for local variable v2 in dyadic
10793 functions. Same for result in exp_term.
10794 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10795 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10796 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10797 (shipout_int): Cast first argument of ntoa to eval_t.
10798 Reported by Thorsten Ohl.
10800 * macro.c: Complete the prototypes of forwarded expand_macro and
10802 Reported by Thorsten Ohl.
10804 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10805 The Ultrix 3.1 compiler cannot do much with void pointers.
10807 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10808 * m4.c (xfree): Replace void * by voidstar.
10809 Reported by Tom McConnell.
10811 * ansi2knr.1: New, from elsewhere.
10812 * Makefile.in (DISTFILES): Distribute ansi2knr.1
10814 * Makefile.in (stamp-h.in): Avoid running ./config.status if
10815 stamp-h does not exist yet. This avoids running it a second time
10816 just after the initial ./configure.
10817 Reported by David MacKenzie and Tom McConnell.
10819 * m4.h: Replace the enum debug_info declaration with a series of
10820 #define's. The Ultrix 3.1 compiler would otherwise need casting
10821 (int) to most references, when used in expressions.
10822 Reported by Tom McConnell.
10824 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
10826 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
10827 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
10828 calls the compiler. Previously, FP_PROTOTYPES was only calling
10829 the preprocessor; by not being subject to CFLAGS, this was
10830 discouraging those flags asking for ANSI compilation.
10831 * acconfig.h: Document HAVE_PROTOTYPES.
10832 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
10833 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
10834 Reported by Eric Backus.
10836 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
10837 from the environment. Default CFLAGS to -g if not set.
10838 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
10839 * lib/Makefile.in: Have CFLAGS substituted from configure.
10840 Reported by Eric Backus and Tom McConnell.
10842 * configure.in: m4_undefine changeword before using AC_ENABLE.
10844 * m4.h: Declare prototypes for error (for ANSI compilers only),
10845 prefix_all_builtins and reference_error.
10846 Reported by Tom McConnell.
10848 * input.c (set_word_regexp): Do not try to initialize the array
10849 test from a string, this does not work with non-ANSI compilers.
10850 Reported by Eric Backus.
10852 * Makefile.in (dist): Clean examples/ before saving it.
10853 (distclean-local): Also remove stamp-h.
10854 Reported by Eric Backus.
10856 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
10857 non ANSI compilers.
10858 Reported by Tom McConnell.
10860 * checks/Makefile.in (clean): Depends on mostlyclean.
10861 (mostlyclean): New goal.
10863 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
10865 * Makefile.in (DISTFILES): Distribute install.sh.
10866 * install.sh: New file, copied from elsewhere.
10867 Reported by Assar Westerlund and Kaveh R. Ghazi.
10869 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
10871 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
10872 * acconfig.h: Explain ENABLE_CHANGEWORD.
10874 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
10875 from code provided by Pete Chown]
10876 * m4.h: Add original_text field to u_t variant of union u.
10877 Declare TOKEN_DATA_FUNC macro.
10878 * builtin.c: Declare changeword.
10879 (m4_changeword): New function.
10880 * input.c: Include "regex.h", define variables with word regexps.
10881 (input_init): Initialize the word regexp.
10882 (set_word_regexp): New.
10883 (next_token): Declare local variables, use the previous code if
10884 default_word_regexp is true. Else, match using a new code. Save

10940 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
10941 49.format check, abusing a `union values' argument with sprintf
10942 without selecting the proper field. Now, save the formatting type
10943 first, delaying the fetch of the corresponding argument.
10944 Reported by Joseph E. Sacco and Tom Quinn.
10946 * format.c (format): Remove const from char *fmt declaration when
10947 not HAVE_EFGCVT, because a NUL may be forced into it.

10997 Reported by Jim Meyering.
10999 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
11001 * m4.h: Move the conditional definition of volatile after the
11002 inclusion of system files, because they may define it first.
11004 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
11006 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
11007 get around a problem with Alpha make seeing a syntax error, there.

11031 syserr() macro. Delete errref, add reference_error and M4ERROR.
11032 * m4.c: Replace errref, which was returning an input reference
11033 string, with reference_error, which prints it on standard error.
11034 * builtin.c, output.c: Use errno as second parameter to error,
11035 instead of using syserr() with %s.
11036 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11037 Doing so, the program name appears after the input reference
11038 instead of before, which eases M-x next-error processing.

11084 expected is on the left and the obtained on the right.
11086 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11087 macros. Delete declarations for m4error, warning, fatal and
11088 internal_error, add declaration for error_message_prefix.
11089 * m4.c: Delete m4error, warning, fatal and internal_error
11090 routines, add error_message_prefix routine.
11091 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11092 warning with WARNING*, fatal with FATAL* and internal_error with
11094 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11095 this is not needed anymore.

11393 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11396 This is still a beta release for the future GNU m4 version 1.1.
11398 * lib/alloca.c: New, from elsewhere.
11399 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11401 * m4.h: Do not define index/rindex if already defined. If
11402 FALSE/TRUE are already defined, do not redefine them, but merely
11403 define boolean typedef to int.
11405 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11406 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11407 because some C compilers do not like connectives with #ifdef.
11408 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11409 __GNUC__ and once for __STDC__.
11410 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11412 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11413 Makefile dependencies. Without it, make keeps destroying and
11414 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11416 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11417 to diversion/DIVERSION, this was a spelling error.
11419 * m4.c: Declare version[], remove #include "version.h".
11420 * version.h: Deleted.
11421 * Makefile.in: Remove references to version.h.
11423 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11424 production, by using a simpler and more robust algorithm. This
11425 solves the problem of synclines sometimes written in the middle of
11426 an output line. Delete sync_line() and output_lines variable.
11427 * m4.h: Remove sync_line prototype and output_lines declaration.
11428 * input.c (next_char), output.c (shipout_text): Remove references
11430 * input.c (push_file, pop_file): Merely put the value -1 in
11431 output_current_line instead of calling sync_line, for delaying a
11432 single `#line NUM FILE' before next output line. Do not test
11433 for sync_output, because this is unnecessary clutter.
11434 * output.c (make_divertion, insert_divertion): Idem.
11435 * input.c: Rename must_advance_line to start_of_input_line, for
11438 * debug.c (trace_header): Select a new debug line format, which
11439 better complies with GNU standards for formatting error messages.
11440 With option `-dfl', M-x next-error might be used on the output.
11441 * m4.c (vmesg): Adjust format of error output to GNU standards.
11442 * m4.texinfo: Adjust examples for `make check' to work.
11444 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11445 case for enum debug_info constants, which were all lower case.
11447 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11449 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11450 collected patches. I tried a few times using newer regex.[ch], it
11451 mysteriously stopped aborting with this one. Insecure feeling...
11452 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11454 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11456 * m4.c: Change `--no-warnings' to `--silent'.
11457 Reported by David MacKenzie.
11459 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11460 leave it off for now. See comment in m4.c for justification.
11461 Reported by David MacKenzie.
11463 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11464 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11466 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11468 * Makefile.in: Ensure recursive cleaning is done before local
11469 cleaning for all clean goals.
11471 * builtin.c (ntoa): Ensure the value is always interpreted as a
11472 signed quantity, whatever the radix is.
11474 1992-11-18 Jim Meyering <meyering@idefix>
11476 * builtin.c, format.c, input.c: Split long lines.
11477 * m4.c: Use typedef macro_definition instead of struct
11479 * symtab.c: Use typedef symbol instead of struct symbol.
11481 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11483 * *.[ch]: Remove all trailing whitespace, in code and comments.
11485 * configure.in: Find some awk.
11486 * Makefile.in: Add $(AWK) to MDEFINES.
11487 * checks/Makefile.in: Transmit $(AWK) to get_them.
11488 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11489 awk script when switching files, because without this, mawk runs
11490 out of file descriptors.
11492 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11494 * Makefile.in (realclean): Delete m4.info*.
11495 Reported by Jim Meyering.
11497 * Makefile.in: Adjust and link with checks/Makefile.
11498 * checks/Makefile.in: New.
11499 * configure.in: Output checks/Makefile.
11501 * checks/get_them: Have the dnl header of each test more
11502 recognizable by next-error, also use a better message.
11504 1992-11-16 Jim Meyering <meyering@idefix>
11506 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11507 And use that only if __GNUC__ since we're using it's GCC-specific
11508 semantics that tell the compiler the associated function doesn't
11511 * builtin.c (substitute): Don't use character as an array index.
11512 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11513 warnings with gcc -W -Wall on systems with qsort prototype.
11514 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11517 * eval.c (most functions): Add parentheses to assignments used
11518 as truth values go avoid warnings from gcc -Wall.
11520 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11521 any functions that don't need external scope.
11523 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11524 (many functions and arrays): Declare `const'.
11526 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11528 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11529 removing the declaration from m4.h. Also rename false to FALSE
11532 * lib/Makefile.in (Makefile): New goal.
11534 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11535 so heavily loaded. It gets more easily overridable, calling make.
11536 Reported by Jim Meyering.
11538 * Makefile.in (dist): Get .fname from the current directory name,
11539 instead of from version.h. I need updating many files manually,
11540 when the version changes, version.h is just one of them.
11542 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11544 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11545 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11546 Reported by Tom McConnell.
11548 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11550 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11551 39.cleardiv, which were describing missing or spurious newlines.
11552 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11553 do not depend on machine word size, `/bin/false' implementation,
11554 or `wc' output format. `make check' is more dependable, now.
11556 * checks/check_them: Summarize the failed tests by listing their
11557 name, at end. If none, issue `All checks successful'. Output
11558 `Checking' instead of `Input file:'.
11560 * checks/get_them, checks/check_them: Reindented.
11562 * Makefile.in (dist): chmod a+r before making the tar file.
11564 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11566 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11568 * input.c (next_token): Reinitialize token_buttom just after using
11569 it as a watermark with obstack_free. Or else, a future token, big
11570 enough for triggering reallocation of the obstack chunk, could
11571 void the initialized value of token_buttom, later causing panic in
11572 obstack_free. Rename token_buttom to token_bottom everywhere.
11574 * m4.h: Before declaring errno, first include <errno.h> and
11575 ensure that it does not define errno.
11576 Reported by Richard Stallman.
11578 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11580 * builtin.c: Define and use DECLARE macro for builtins.
11582 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11583 argument, this is a common idiom for introducing long comments.
11585 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11586 arguments. The last argument was silently ignored.
11588 * m4.c (cmd_error): Add a missing semicolon before va_end().
11590 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11592 * Makefile.in: Now handle protoized sources. Define and use U.
11593 Compile and use ansi2knr with old compilers. Update DISTFILES.
11594 Add `aclocal.m4' to `configure' dependencies.
11595 * ansi2knr.c: New, from Ghostscript distribution.
11596 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11597 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11598 * aclocal.m4: New, provide FP_PROTOTYPES.
11599 * m4.h: Conditionnaly protoized through Args, save for varags.
11600 * builtin.c: Protoized. Then:
11601 Include <sys/types.h> if size_t is not defined, before "regex.h".
11602 (m4_ifelse): Fetch built-in name properly for diagnostic.
11603 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11604 (m4_regexp): Add const to `msg' declaration.
11605 (m4_patsubst): Add const to `msg' declaration.
11606 * debug.c: Protoized, save for varargs.
11607 * eval.c: Protoized.
11608 * format.c: Protoized.
11609 * input.c: Protoized.
11610 * m4.c: Protoized, save for varargs. Then:
11611 (xfree): Accept void * instead of char *.
11612 (xmalloc): Return void * instead of char *.
11613 (xrealloc): Accept and return void * instead of char *.
11614 * macro.c: Protoized.
11615 * output.c: Protoized.
11616 * path.c: Protoized. Then cast some (char *) over xmalloc's.
11617 * symtab.c: Protoized.
11619 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
11621 * m4.texinfo: Remove directory from diagnostics in 30.include,
11622 51.eval, 56.errprint and 57.m4exit tests.
11624 * m4.h: Remove declarations for int or void system functions, they
11625 cause more conflicting trouble than they make good.
11627 * configure.in: Avoid configuration header file. Add some tests.
11628 * m4.h: Remove #include "config.h".
11629 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
11630 Then, rewritten for better compliance with GNU standards.
11632 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
11634 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
11635 because of a misplaced #endif.
11637 * Many *.[hc] files: Correct intra-line spacing here and there,
11638 according to GNU indent 1.6 advice.
11640 * configure.in: New, using Autoconf 1.2.
11641 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
11642 * Delete old configure.in, configure, etc/configure.in,
11643 etc/configure, lib/configure.in, lib/configure and config/*.
11644 Reported by Jason Merrill.
11646 * symtab.c (hash): Change (char) NULL to '\0'.
11647 Reported by Jason Merrill.
11649 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
11650 etc/nextvers.sh. Release numbers will be edited `by hand'.
11651 * version.h: De-automatize, force value in.
11653 * m4.c: Changes in order to use a newer getopt.h.
11654 Reported by David MacKenzie.
11656 * checks/: New name for examples/.
11657 * checks/get_them: New location for etc/get_examples.
11658 * checks/check_them: New location for etc/check_examples.
11659 * Makefile.in, checks/get_them, checks/check_them: Adjust.
11660 * lib/vfprintf.c: New location for etc/vfprintf.c.
11661 * Delete empty etc/.
11662 * examples/: New name for test/.
11664 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
11666 * Makefile.in (check): Add m4 as dependency.
11668 * m4.c: Accept --no-warnings instead of --no_warnings, and
11669 --no-gnu-extensions instead of --no_gnu_extensions. Make the
11670 usage message more informative.
11671 Reported by David MacKenzie.

11682 code disposition by hand.
11684 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
11686 * m4.h: Delete definitions for abort() and exit().
11687 Reported by Richard Stallman.
11689 * config/hmake-unicos, config/s-unicos.h: New files.
11690 Reported by Hal Peterson.

11703 reports and feedback.
11705 * Uses GNU configure, taken from the gdb distribution.
11707 * Uses GNU getopt(), with long option names.
11709 * The -Q/+quiet option is added, which suppresses warnings about
11710 missing or superflous arguments to built-in macros.
11712 * Added default options via the M4OPTS environment variable.
11714 * The built-in format can now be configured to use sprintf as
11715 the formatting engine, for systems without [efg]cvt(3).
11717 * GNU library code is moved to the ./lib subdirectory; other
11718 utility files are now in ./etc.
11720 * Several minor bugs have been fixed.
11722 1991-07-26 René Seindal <seindal@diku.dk>
11724 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
11725 François Pinard and Roland H. Pesch for providing me with reports.
11727 * The builtins incr and decr are now implemented without use of
11730 * The builtin indir is added, to allow for indirect macro calls
11731 (allows use of "illegal" macro names).
11733 * The debugging and tracing facilities has been enhanced
11734 considerably. See the manual for details.
11736 * The -tMACRO option is added, marks MACRO for tracing as soon
11739 * Builtins are traced after renaming iff they were before.
11741 * Named files can now be undiverted.
11743 * The -Nnum option can be used to increase the number of
11744 divertions available.
11746 * Calling changecom without arguments now disables all comment
11749 * The function m4_patsubst() is now consistently declared
11752 * A bug in dnl is fixed.
11754 * A bug in the multi-character quoting code is fixed.
11756 * Several typos in the manual has been corrected. More probably
11759 * The m4.info file is now installed along with the program.
11761 1990-11-15 René Seindal <seindal@diku.dk>
11763 * Updated and enhanced version. Release 0.75, manual 0.07.
11765 * Implemented search path for include files (-I option and
11766 M4PATH envronment variable).
