| Factor load functionality into include builtin. |
| * m4/module.c (m4__module_open): Instead of calling lt_dlopenext |
| right away, use the preload hint first incase path searching has |
| been disabled by POSIXLY_CORRECT. Otherwise fallback to a |
| manual path search to override libltdl's algorithm. |
| * m4/m4module.h: Adjust. |
| * m4/path.c (FILE_SUFFIXES): Order to try suffixes in our path |
| search algorithm. |
| (NO_SUFFIXES): Alternatively, how to to search a path without |
| adding file suffixes. |
| (m4_path_search): Add a new suffixes parameter defaulting to |
| NO_SUFFIXES. Adjust all callers. |
| (m4_load_filename): New generic load function that tries to |
| open a matched file first as a module, and if that fails fall |
| back to as (possibly frozen) m4 input. |
| (m4_fopen): New function with close on exec functionality. |
| * modules/m4.c (include, sinclude): Use m4_load_filename to |
| overload these builtins to work with modules too. |
| * modules/load.c (load): Removed this builtin. |
| * src/main.c: Remove Dynamic loading features section, and |
| M4MODPATH support. |

| any more. |
| * doc/m4.texinfo: Update examples. |
| (Dynamic loading features, Load): Removed. |
| (Command line files): Describe how non-option arguments are |
| treated to try to find a matching macro file or dso. |
| (Include): Describe additional dso loading features if a |
| suitable text file cannot be found. |

| |
| Stage 22: allow builtin token concatenation outside $@. |
| Adjust the input and argument parsing engines to append builtins |
| alongside text. Make define warn when builtins must be |
| flattened. |
| Memory impact: slight penalty, with fewer builtins flattened. |

| Reported by Elbert Pol. |
| |
| 2008-04-14 Eric Blake <ebb9@byu.net> |
| |
| Stage 21b: $@ concatenates builtins, m4wrap takes builtins. |
| Improve arg_print to handle builtin tokens when printing to a |
| known chain, rather than always flattening builtins. This allows |
| m4wrap and $@ back-references to handle embedded builtin tokens. |
| Memory impact: none. |
| Speed impact: slight penalty, from more bookkeeping. |
| * m4/m4module.h (m4_push_builtin): Add parameter. |
| (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish) |
| (m4_arg_print, m4_symbol_value_print): Rename and reduce scope... |
| * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init) |
| (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print): |
| ...to these, in some cases adding a parameter. |
| (m4__append_builtin): New prototype. |
| * m4/builtin.c (m4_builtin_print): Alter signature to print |
| builtin to a growing symbol chain. |
| * m4/symtab.c (m4__symbol_value_print): Alter signature. |
| (m4_symbol_print, dump_symbol_CB): Adjust callers. |

| blocks now. |
| (struct m4_input_block): Delete u.builtin member. |

| (Debuglen): Adjust expected output. |
| |
| Stage 21a: Optimize checks for end of input. |
| Create a new polymorphic input block type, which always fails with |
| CHAR_EOF, so that remaining input routines no longer have to check |
| for NULL input block. |
| Memory impact: none. |
| Speed impact: noticeable improvement, from fewer conditionals. |
| * m4/input.c (eof_funcs, input_eof): New objects. |
| (eof_peek, eof_read, eof_unget): New functions. |

| (m4_input_exit): Use placeholder to guarantee non-NULL isp and |
| wsp. |
| (next_char): Rename retry to allow_unget, and change sense for |
| easier manipulation. All callers changed. |
| |
| Improve OS/2 detection. |
| * modules/gnu.c (m4_macro_table): Ensure all possible identifiers |
| are defined, not just the first. The testsuite ensures that |
| exactly one gets defined. |
| * m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter |
| what other pre-defined macros it has. |
| * THANKS: Update. |
| Reported by Elbert Pol. |
| |
| Ensure __m4_version__ is unquoted. |
| * tests/builtins.at (__m4_@&t@version__): Augment test. |
| |
| Avoid GNU make failure on tarball. |
| * Makefile.am (EXTRA_DIST): Distribute cfg.mk and maint.mk. |
| |
| 2008-04-10 Eric Blake <ebb9@byu.net> |

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

| (Format): Add test of C99 hex-float parsing. |
| * NEWS: Mention 1.4.11 release. |
| * tests/builtins.at (divert): Add additional test. |
| |
| 2008-04-08 Eric Blake <ebb9@byu.net> |
| |
| Overhaul inter-version releases to work with git. |
| * configure.ac (version): New variable, which has nicer version |
| contents when using git 1.5.5+, hardcoded to 1.9a otherwise. |
| (TIMESTAMP): Delete, since CVS id expansion died with transition |
| to git. |
| (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits. |
| * build-aux/mkstamp: Delete, no longer used. |
| * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up |
| rebuilds when timestamps don't matter. |
| (MKSTAMP): Delete, no longer used. |
| (EXTRA_DIST): No longer worry about mkstamp. |
| (.version): New rule and distributed file. |

| |
| 2008-03-18 Eric Blake <ebb9@byu.net> |
| |
| Stage 20b: make m4wrap obey POSIX fifo ordering. |
| Improve input engine to support location changes within symbol |
| chains, then convert m4wrap to always build symbol chain. |
| Memory impact: none. |
| Speed impact: slight penalty, from more m4wrap bookkeeping. |
| * m4/m4module.h (m4_wrap_args): Add prototype. |
| * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC. |
| (struct m4__symbol_chain): Add struct u_l. |

| link. |
| * m4/macro.c (m4_wrap_args): New function. |
| * modules/m4.c (m4wrap): Use it. |

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

| (Shift): Document the composite macro join. |
| (Incompatibilities): Move documentation of LIFO vs. FIFO... |
| (M4wrap): ...here, to match improved example. |
| |
| 2008-03-13 Eric Blake <ebb9@byu.net> |
| |
| Stage 19c: allow builtin tokens in more macros. |
| Allow builtin tokens inside symbol chains, although for now, they |
| are not allowed inside comments or quotes. Enable builtin token |
| handling in more macros, if only to consistently diagnose invalid |
| macro names. |
| Memory impact: none. |
| Speed impact: slight impact, due to more bookkeeping. |
| * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New |
| prototypes. |
| * m4/m4private.h (enum m4__symbol_chain_type): Add |
| M4__CHAIN_FUNC. |

| Handle builtin tokens. |
| (arg_symbol): Add parameter, and allow NULL level. |
| (m4_arg_symbol, m4__push_arg_quote): Adjust callers. |
| (m4_arg_text): Ensure all builtins have been flattened. |
| * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon) |
| (undefine, m4_dump_symbols): Warn on invalid macro names. |
| (ifdef, ifelse, shift): Handle builtin tokens. |
| * modules/gnu.c (m4symbols): Likewise. |
| * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new |
| behavior. |
| (Debuglen): Likewise, and remove xfail. |
| * NEWS: Mention the change. |
| |
| Stage 19b: invert sense of bit for handling builtin tokens. |
| Pass builtin tokens by default, rather than as the exception, so |
| that the logic can consistently refer to flattening arguments. |
| Memory impact: none. |
| Speed impact: none. |
| * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro. |
| (M4_BUILTIN_GROKS_MACRO): Rename... |
| (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense. |
| (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise... |
| (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to |
| this. |

| (m4_symbol_value_flatten_args): ...to this. |
| * m4/macro.c (collect_arguments): Accomodate changed sense. |
| * m4/module.c (m4__module_open): Require arguments if flattening |
| is requested. |
| * m4/input.c (m4_push_string_finish): For now, flatten all |
| builtins pushed as back-references. |

| are stringized without preprocessor expansion. |
| * doc/m4.texinfo (Defn): Update comments to match reality. |
| (Debuglen): Update test now that user macros pass builtin tokens. |
| |
| Stage 19a: sort and cache builtins loaded by a module. |
| Rather than repeatedly using dlsym to browse the builtin table, |
| copy off the table at module load time. Then, the input engine |
| merely refers to the copy instead of duplicating information. |
| Memory impact: slight penalty, due to more memory per module, but |
| offset by less memory in input engine. |
| Speed impact: slight improvement, due to faster builtin lookups. |
| * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use |
| m4_builtin_find_by_* instead. |
| (m4_builtin_find_by_func): Change return type. |

| fields can be determined from builtin. |
| (builtin_peek, builtin_read, builtin_unget, init_builtin_token) |
| (m4__next_token): Alter parsing so that only init_builtin_token |
| consumes a builtin. |

| |
| Stage 18: try harder to reuse argv in recursion. |
| When pushing arguments that contain an existing $@ ref, reuse the |
| ref rather than creating another layer of wrappers. |
| Memory impact: noticeable improvement, due to better $@ reuse. |
| Speed impact: noticeable improvement, due to O(n^2) to O(n) |
| reduction in unboxed recursion. |
| * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible. |
| (m4_push_args): Let make_argv_ref take care of pending data. |

| |
| Stage 17: pass argv through quoted strings. |
| Allow the concatenation of $@ references with other text input |

| wrapper around many arguments vs. a reference serving as part of a |
| single argument. Also optimize based on whether argv contains |
| builtin tokens that might need flattening to the empty string. |
| Memory impact: noticeable improvement, due to O(n^2) to O(n) |
| reduction from total reuse of $@ references. |
| Speed impact: noticeable improvement, due to O(n^2) to O(n) |
| reduction in boxed recursion. |

| |
| 2008-02-20 Eric Blake <ebb9@byu.net> |
| |
| Stage 16: cache quotes and improve m4_arg_print. |
| Cache rather than always copying quotes when pushing $@ refs; in |
| particular, reconstruct single-byte quotes on the fly. Allow NUL |
| through m4wrap. Improve sharing of code that prints arguments. |
| Memory impact: slight improvement, due to cached quotes. |
| Speed impact: slight improvement, due to less copying. |

| (m4_symbol_print, dump_symbol_CB): Adjust all callers. |
| * m4/utility.c (m4_dump_args): Delete; callers should use |
| m4_arg_print instead. |
| * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split |
| implementation, and allow embedded NUL. |
| (m4_print_token, pop_input, composite_print, composite_peek): |
| (composite_read, append_quote_token): Adjust all callers. |
| * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref): |

| * doc/m4.texinfo (Improved forloop): Document advantage of $0. |
| (Improved foreach): Adjust dump from file. |
| |
| Stage 15: return argv refs back to collect_arguments. |
| Collect an entire $@ reference at once rather than one argument at |
| a time, outside of quotes (but inside quotes, $@ is still |
| flattened for now). The skip_last field allows concatenation of |
| $@ with other text when collecting arguments. |
| Memory impact: noticeable improvement, due to better reuse of $@. |
| Speed impact: noticeable improvement, due to less parsing. |
| * m4/m4private.h (CHAR_ARGV): New input engine sentinel. |

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

| |
| Stage 11: full circle for single argument references. |
| Pass quoted strings through to argument collection in a single |

| 2008-01-16 Eric Blake <ebb9@byu.net> |
| |
| Stage 10: avoid extra copying of strings and comments. |
| When collecting tokens that are immune to further expansion, avoid |
| copying data from one obstack to another by outputting it into the |
| destination obstack to begin with. Also reduce copying done in |
| format builtin. |
| Memory impact: slight improvement, due to better obstack usage. |
| Speed impact: noticeable improvement, due less data copying. |

| * modules/m4.c (ntoa): Tighten buffer size. |
| * m4/output.c (m4_tmpname): Guarantee no buffer overflow. |
| * modules/format.c (arg_int, arg_long, arg_double): New helper |
| functions, to detect overflow or unparsed characters. |
| (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for |
| missing or excess arguments. |

| |
| * TODO: Update with some newer URLs. |
| |
| Verify linear `index'. |
| * tests/builtins.at (index): New test. |
| (translit): Make test take longer, to make quadratic algorithms |
| more apparent. |
| |
| 2007-12-20 Eric Blake <ebb9@byu.net> |
| |
| Stage 9: share rather than copy single-arg refs. |
| Use hooks of previous patch to create back-references to arguments |
| in the input engine, and inline short text rather than always |
| creating a FIFO link. Also start testing embedded NUL behavior. |
| Until the argument collection engine also shares references, the |
| memory usage increases. |
| Memory impact: noticeable penalty, due to longer life of argv |
| changing O(n) to O(n^2) on boxed recursion. |
| Speed impact: slight improvement, due less data copying. |
| * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules. |
| * m4/m4module.h (m4_arg_scratch): New prototype. |
| * m4/m4private.h (m4__push_symbol): Add parameter. |
| (m4_arg_scratch): Add fast accessor. |
| (struct m4): Add expansion_level member, taken... |
| * m4/macro.c (expansion_level): ...from here. Adjust all users. |
| (expand_argument): Minor cleanup. |
| (expand_macro): Track scratch space per macro call. |
| (m4_arg_scratch): New function. |
| (m4_make_argv_ref): Call new function. |
| (m4_push_arg): Push reference to $0. |
| (m4_push_args): Rework separator usage, since separators will |
| usually be inlined. |
| (process_macro): Allow embedded NUL. |
| * m4/input.c (INPUT_INLINE_THRESHOLD): New define. |
| (m4__push_symbol): Add parameter. Inline short strings, and save |
| references through rescanning. |
| * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion. |
| * modules/m4.c (errprint, index): Handle NUL transparently. |
| (dumpdef, translit): Use scratch space, rather than expansion |
| stack. |
| * modules/gnu.c (renamesyms, m4symbols): Likewise. |
| * tests/others.at (nul character): New test. |
| (iso8859): Quote absolute file name, remove XFAIL. |
| * tests/iso8859.m4: Avoid raw NUL in output. |
| * tests/null.m4: New file. |
| * tests/null.out: Likewise. |
| * tests/null.err: Likewise. |
| * Makefile.am (OTHER_FILES): Distribute new files. |
| * .gitattributes: Treat new files as text. |
| |
| 2007-12-17 Eric Blake <ebb9@byu.net> |
| |
| Stage 8: extend life of references into argv. |
| Add hooks to lengthen the lifetime of arguments reused in a macro |
| expansion, rather than always discarding arguments at the end of |
| expand_macro. Rework the expand_macro obstacks to handle longer |
| lifetimes. For now, the hooks remain unused. |
| Memory impact: slight penalty, due to larger structs. |
| Speed impact: slight penalty, due to more bookkeeping. |
| * m4/system_.h (obstack_regrow): Delete. |
| * m4/m4private.h (struct m4_symbol_chain): Add level field. |
| (m4__push_symbol): Adjust prototype. |
| (m4__adjust_refcount): New prototype. |

| (struct m4__macro_arg_stacks): New structure. |
| (struct m4): Add arg_stacks, stacks_count fields. |
| * m4/m4module.h (m4_make_argv_ref): Add parameter. |
| * m4/macro.c (argc_stack, argv_stack): Delete, replaced by |
| context->arg_stacks. |
| (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks, |
| conditional on M4_DEBUG_MACRO envvar. |
| (collect_arguments): Adjust signature. |
| (expand_macro): Rework obstack handling. |
| (m4__adjust_refcount, arg_mark): New functions. |
| (m4_make_argv_ref): Populate new field. |
| (m4_push_arg, m4_push_args): Track inuse. |
| (process_macro): One less cast. |
| * m4/m4.c (m4_delete): Clean up arg_stacks. |

| example. |
| |
| 2007-12-13 Eric Blake <ebb9@byu.net> |
| |
| Yet more rewording. |
| * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in |
| the previous patch. |
| |
| * THANKS: Update. |
| |
| 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change) |
| |
| * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting |
| example. |
| Reported by Giovanni Toffetti. |
| |
| 2007-12-11 Eric Blake <ebb9@byu.net> |
| |
| Stage 7: use chained input support in input parser. |
| Allow the LIFO input engine to rescan a macro expansion composed |
| of smaller chunks of FIFO data, rather than the old approach of a |
| monolithic string. For now, all chunks are still copied. |
| Memory impact: slight penalty, due to FIFO chain overhead. |
| Speed impact: slight penalty, due to extra bookkeeping. |
| * m4/m4private.h (m4__push_symbol): New prototype. |
| (struct m4_symbol_chain): Add const-safety. |
| * m4/symtab.c (m4_symbol_value_print): Simplify. |
| (dump_symbol_CB): Update caller. |
| * m4/input.c (struct m4_input_block): Alter u_c member, first |
| introduced 2006-10-25, but unused until now. |
| (composite_peek, composite_read, composite_unget) |
| (composite_print, init_builtin_token): Rewrite accordingly. |
| (m4_push_wrapup): No longer need trailing NUL. |
| (m4__push_symbol, make_text_link): New functions. |
| (m4_push_string_finish): Use them. |
| * m4/macro.c (m4_push_arg, m4_push_args): Likewise. |
| (expand_macro): Simplify logic of nesting_limit. |
| * src/main.c (main): Likewise. |
| * doc/m4.texinfo (Dumpdef): Augment test. |
| |
| 2007-12-08 Eric Blake <ebb9@byu.net> |
| |
| Stage 6: convert builtins to push arg at a time. |
| Add new methods to factor all builtins whose expansion includes an |
| argument, making back-reference creation easier in future patches. |
| Factor out length-limited printing to obstacks, and use -1 rather |
| than 0 for unlimited length. |
| Memory impact: none. |
| Speed impact: slight improvement, due to better code sharing. |
| * m4/m4module.h (m4_shipout_text): Rename... |
| (m4_divert_text): ...to this, to avoid confusion with m4_shipout_* |
| that does not worry about sync lines. |
| (m4_shipout_string_trunc): New prototype. |
| * m4/output.c (m4_shipout_text): Rename... |
| (m4_divert_text): ...to this. |
| (m4_shipout_string): Move guts... |
| (m4_shipout_string_trunc): ...to this new function. |
| * m4/macro.c (m4_push_arg, m4_push_args): New functions. |

| Likewise. |
| * modules/gnu.c (patsubst): Likewise. |
| (debuglen): Use SIZE_MAX for unlimited debug length. |
| * src/main.c (main): Likewise. |
| * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not |
| zero. |
| |
| 2007-12-07 Eric Blake <ebb9@byu.net> |
| |
| Minor security fix: Quote output of mkstemp. |
| * modules/m4.c (m4_make_temp): Produce quoted output. |
| * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and |
| tests. |
| |
| Stage 5: add notion of quote age. |
| Cache the quoting rules that were in effect when a string was |
| parsed, to avoid reparsing that string if no changequote or other |
| quote age change took place in the meantime. A quote_age of 0 is |
| always safe, but does not benefit from caching. |
| Memory impact: slight improvement, due to smaller struct in input |
| engine. |
| Speed impact: slight penalty, due to more bookkeeping. |
| * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype. |
| (m4_set_symbol_value_text): Adjust prototype. |
| (m4_has_syntax): Factor out the unsigned char cast. |
| * m4/m4private.h (struct m4_syntax_table): Add syntax_age and |
| quote_age members. |
| (m4__quote_age, m4__safe_quotes): New accessor macros, no need for |
| functions at this point. |
| (struct m4_symbol_value, struct m4_macro_args): Add quote_age |
| member. |
| (m4_set_symbol_value_text): Adjust fast accessor. |
| (m4_get_symbol_value_quote_age): New fast accessor. |
| * m4/symtab.c (m4_set_symbol_value_text): Add parameter. |

| (m4_macro_expand_input): Update callers. |
| (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch. |
| * m4/input.c: Comment cleanups. |
| (struct m4_input_block): Reduce size. |
| (m4__next_token): Report quote age. |
| (m4_push_builtin, init_builtin_token): Update callers. |
| * m4/utility.c (skip_space): Adjust callers. |
| * m4/module.c (install_macro_table): Likewise. |
| * m4/syntax.c (m4_set_syntax): Initialize and update quote age. |
| (m4_set_quotes, m4_set_comment): Detect no-op changes, and update |
| quote age. |
| (set_quote_age): New helper function. |
| (check_is_single_quotes, check_is_single_comments): Adjust |
| callers. |
| * src/freeze.c (reload_frozen_state): Likewise. |
| * src/main.c (main): Likewise. |
| * modules/m4.c (define, pushdef): No need to set macro text. |
| * tests/builtins.at (changequote, defn): New tests. |
| * examples/wrapfifo.m4: New file. |
| * examples/wraplifo.m4: New file. |
| * Makefile.am (dist_pkgdata_DATA): Distribute new examples. |
| |
| 2007-12-04 Eric Blake <ebb9@byu.net> |
| |
| Fix builds with OpenBSD make. |
| * Makefile.am (HELP2MAN): New macro. |
| (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into |
| srcdir. |
| * README: Update copyright. |
| * HACKING: Mention help2man and makeinfo dependencies. |
| |
| 2007-11-29 Eric Blake <ebb9@byu.net> |
| |
| Stage 4: route indir, builtin through ref; make argv opaque. |
| Finish making struct opaque to all but the input engine, by |
| reworking obstack usage in expand_macro to better support creation |
| of a $@ reference. Canonicalize the empty argument, to allow |
| pointer comparison optimizations. |
| Memory impact: slight penalty, due to larger struct. |
| Speed impact: slight improvement, due to fewer function calls. |
| * m4/system_.h (obstack_regrow): Fix precedence. |
| * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref): |
| New prototypes. |
| (struct m4_macro_args): Move... |
| * m4/m4private.h (struct m4_macro_args): ...here, making it opaque |
| to modules. Add has_ref member. |
| (bool_bitfield): New helper typedef. |
| (struct m4_symbol_chain): Add flatten and len members. |
| * m4/macro.c (empty_symbol): New placeholder, for optimizing |
| comparison with empty string. |

| (undefine, popdef, m4_dump_symbols): Optimize. |
| * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new |
| methods. |
| (changesyntax, regexp): Optimize. |
| * m4/output.c (diversion_storage): Use typedef. |
| |
| Stage 3b: cache length, rather than computing it, in modules. |
| Use cached token length in builtins and output engine. |
| Memory impact: none. |
| Speed impact: noticeable improvement, due to fewer function calls. |
| * m4/hash.c (m4_hash_remove): Avoid double free on remove |
| failure. |
| * m4/output.c (m4_shipout_string): Change semantics of len param. |

| * m4/symtab.c (m4_symbol_value_print): Likewise. |
| * modules/gnu.c (__file__, __program__, builtin, indir) |
| (m4symbols, mkdtemp, regexp_compile, regexp_substitute, |
| renamesyms, patsubst, regexp, regexp_compile): Likewise. |

| * doc/m4.texinfo (Renamesyms, Dumpdef, Changesyntax): Adjust test. |
| * tests/builtins.at (mkstemp): Likewise. |

| length-based handling allows NUL through part but not all of M4. |
| |
| 2007-11-28 Eric Blake <ebb9@byu.net> |
| |
| Stage 3a: cache length, rather than computing it, in libm4. |
| Cache the length of a token in the input engine and symbol table, |
| to avoid repeating lots of strlen calls. Additionally, by using |
| obstack length rather than strlen, the input engine can now |
| support embedded NUL. |
| Memory impact: slight penalty, due to larger struct. |
| Speed impact: slight improvement, due to fewer function calls. |
| * m4/m4module.h (struct m4_macro_args): Cache length. |

| (m4_set_symbol_value_placeholder): Update accordingly. |
| (m4_set_symbol_value_text): Change signature. |
| (m4_get_symbol_value_len): New accessor. |
| * m4/input.c (struct m4_input_block, string_peek, string_read) |
| (string_unget, string_print, m4_push_string_finish) |
| (m4_push_wrapup): Track length of string input. |
| (m4__next_token): Adjust all users of symbol text to track length, |
| too. |

| (m4_get_symbol_value_text, m4_get_symbol_value_placeholder) |
| (m4_set_symbol_value_text, m4_set_symbol_value_placeholder): |
| Adjust implementation. |
| |
| 2007-11-27 Eric Blake <ebb9@byu.net> |
| |
| Stage 2: use accessors, not direct reference, into argv. |
| Outside of macro.c, use accessor methods rather than direct access |
| into the argv struct. |
| Memory impact: none. |
| Speed impact: slight penalty, due to increased function calls. |
| * m4/m4private.h (m4_arg_argc): New fast accessor. |
| * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text) |
| (m4_is_arg_func, m4_arg_text, m4_arg_len, m4_arg_func): New |
| prototypes. |
| (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args) |
| (m4_macro_call): Make argc unsigned. |
| (M4ARG): Use new accessors. |
| * modules/m4.c (define, pushdef): Likewise. |
| (undefine, popdef, ifelse, m4_dump_symbols, defn, undivert) |

| * modules/evalparse.c (m4_evaluate): Likewise. |
| * modules/gnu.c (builtin, indir): Use new accessors. |
| (changesyntax): Make argc unsigned. |
| * modules/perl.c (perleval): Likewise. |

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

| * m4/utility.c (m4_verror_at_line): New helper method. |
| (m4_error, m4_error_at_line, m4_warn, m4_warn_at_line): Add new |

| 2007-11-14 Eric Blake <ebb9@byu.net> |
| |
| Handle some defn corner cases differently. |
| * doc/m4.texinfo (Defn): Update documentation; although this still |
| doesn't match the branch, since it may be changed before 2.0. |
| * m4/macro.c (expand_argument): Consistently ignore builtins in |
| concatenation contexts. |
| * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug. |
| |
| 2007-11-13 Eric Blake <ebb9@byu.net> |
| |
| Note: Patches titled Stage 0 through N form a series of patches |
| which decreases the algorithmic complexity of tail recursion in |
| macro expansions from O(n^2) to O(n) in both time and memory, then |
| performs cleanups, such as handling of embedded NUL, made easier |
| by the code refactoring. |
| |
| Stage 0: Fix memory leak in tail recursion. |
| Free expansion text in the input engine as soon as it is parsed, |
| rather than when the recursive expansion completes. |
| Memory impact: noticeable improvement, due to reduction from |
| O(n^2) to O(n) on recursion. |
| Speed impact: minor improvement, due to better memory usage. |
| * m4/input.c (pop_input): Add flag parameter and return type. |
| (next_char): Adjust caller. |
| (m4_push_string_init): Let go of memory earlier. |
| |
| 2007-11-07 Eric Blake <ebb9@byu.net> |

| M4 was designed to have a small number of header files defining |

| |
| * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit. |
| (clean-local): Split into and depend upon... |

| |
| 2006-06-19 Eric Blake <ebb9@byu.net> |

| path to testsuite here, rather than relative path to testsuite |
| elsewhere. |
| |
| 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> |

| |
| Avoid compiler warnings. |
| * m4/macro.c (trace_format): Don't mark this as a printf format, |

| 2005-12-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * bootstrap (func_update_po): Test and set $WGETFLAGS to disable |

| we can teach make about the dependencies between the m4 binary and |
| the preopened modules it is built against: |
| |
| * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of |
| preopened modules. |
| * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any |
| of the preopened modules have changed. |
| |
| 2005-05-07 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.ac (gl_MODULES): Add mkstemp for machines that don't |
| have a native implementation. |
| |
| 2005-05-06 Gary V. Vaughan <gary@gnu.org> |
| |
| * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are |
| handled already by gnu/exit.h. |
| |
| * configure.ac (gl_MODULES): Add assert to support a |
| --disable-assert configure time option for NDEBUG setting. |
| |
| * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c. |
| * bootstrap (src_modules): Add version-etc-fsf. |
| * src/main.c (version_etc_copyright): Removed. |
| |
| * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4. |
| |
| 2005-05-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin |
| recognition macros. |
| * src/freeze.c (produce_frozen_state): Use \n line-endings even |
| on Windows, so that the frozen file reader will work. |

| Forward port of a patch that allowed m4-1.4.2 to compile on |
| QNX 6.3: |
| |
| * configure.ac (AC_CHECK_HEADERS): Add signal.h, |
| sys/signal.h. |
| * src/m4.h: And include them as appropriate. |
| * src/main.c, src/stackovf.h: Don't include signal.h literally; |
| m4.h will include the correct file. |
| |
| 2005-05-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/m4private.h: Make errno visible for the sources patched |
| below. |
| |
| 2005-05-04 Paul Eggert <eggert@twinsun.com> |
| |
| * src/main.c (print_program_name_CB): Preserve errno, since |
| M4ERROR relies on this. |
| * modules/gnu.c (m4_esyscmd): Clear errno before calling popen. |
| * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp. |
| * m4/path.c (m4_path_search): Don't let "free" trash errno when |
| returning NULL. |
| |
| * m4/output.c (m4_insert_file): Don't assume errno has a valid |
| value simply because fread returns zero. This fixes a |
| portability bug reported by Marion Hakanson in |
| <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>. |

| |
| Gnulib has changed again. Reimport. Adjust. Rinse. Repeat. |
| Automake and Libtool now agree on subdir-objects and LTLIBOBJS, |
| and libtoolize does a better job of ltdl importing now too, so |
| take advantage of that while updating the tree: |
| |
| * acm4, config: Moved from here... |
| * ltdl/m4, ltdl/config: ...to here. |
| * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am, |
| src/Makefile.am, tests/Makefile.am: Removed... |
| * Makefile.am: ...and migrated to here, with adjustments to |
| compensate for relative path differences. |
| * commit: Adjust relative paths. |
| * configure.ac: Adjust relative paths. |
| (AC_PREREQ): 2.59 isn't strictly new enough, we also need a |
| patch. |
| (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In |
| the meanwhile, CVS HEAD libtool is needed. |
| (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't |
| stricly new enough, we also need a patch. |
| (AM_PROG_CC_C_O): Required for subdir-objects in Automake. |
| (AC_WITH_LTDL): Replaced with LT_WITH_LTDL. |
| (gl_MODULES): Don't list getopt and version-etc, as they don't |
| belong in libm4. |
| * bootstrap: After running gnulib-tool to import the listed |
| modules, fetch getopt and version-etc into src manually. |
| (ltdldir): Change to ltdl. |
| * src/main.c: Adjust for changes in version-etc API. |
| * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4, |
| but works when the getopt module isn't to be included in the lib. |
| * README: Add note about patching autoconf and automake to |
| bootstrap CVS m4. |

| common security hole. |
| * modules/m4.c (m4_maketemp): Implement the above, by using |
| mkstemp rather than mktemp. |

| |
| * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table): |

| parenthesising the expanded function names. |
| * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote) |

| function definitions to the end of the file so that any |
| invocations in the rest of the file pick up the fast macro |

| to gnu. |
| |
| 2004-09-23 Gary V. Vaughan <gary@gnu.org> |
| |
| * src/main.c: Include gnulib files from the correct directory. |
| |
| * gnulib/*: Don't store any of the gnulib files in arch, as they |
| generate spurious changes. |
| * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the |
| gnulib macros now share our macro directory. |
| (SUBDIRS): Descend into `gnu' rather than `gnulib'. |
| * bootstrap: Call gnulib-tool to import from the gnulib tree. |
| (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H, |
| gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of |
| the gettext macros from autopoint that overwrite the gnulib-tool |
| imported versions. Import sources and Makefile.am into the `gnu' |
| directory. Changed all callers. |
| * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES, |
| gl_INIT): Call these gnulib-tool macros instead of the hardcoded |
| for imported modules. |
| * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4, |
| acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than |

| |
| Latest CVS libtool can preload modules in libraries, including |
| its own module loaders! Tweak m4 so that it doesn't try to treat |
| libltdl's module loaders as m4 modules when freezing and on exit: |
| |
| * gnulib/acm4/*.m4: Don't store these files in arch since they |
| generate spurious changes. |
| * bootstrap: Simplify initial libtoolize call, since CVS |
| libtoolize is smarter these days. |
| * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH |
| build. |
| * m4/module.h (m4__module_exit): Missing declaration. |
| * m4/m4private.h (m4__module_next): New function declaration. |
| * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t |
| encapsulation. Changed all callers. |
| (m4__module_interface): New function to verify m4 loadable module |
| interfaces. |
| (m4__module_init): Register the interface validator. |
| (m4__module_exit): Only close my own modules. |
| * modules/m4.c (unistd.h): Provide missing declaration. |
| (m4_set_sysval, m4_sysval_flush, m4_dump_symbols) |
| (m4_expand_ranges): More missing declarations. |
| * modules/modtest.c (export_test): Ditto. |
| * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory. |
| * src/main.c (main): Bump copyright year. |
| * tests/modules.at: Fix sed syntax error. |
| |
| |
| 2004-06-17 Gary V. Vaughan <gary@gnu.org> |
| |
| Tweaking to enable compilation with latest CVS libtool and |
| libltdl. We can't just dump the library files directly into the |
| m4 directory anymore now that libltdl is built from pieces itself: |
| |
| * bootstrap: Rewritten to use latest libtoolize sanely, and to |
| set up libltdl subdirectory. |
| * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the |
| gnulib subdirectory's config. |
| (TIMESTAMP): Use $ac_aux_dir for VPATH builds. |
| (m4_pattern_forbid): Remove the cruft to deal with renamed jm_ |
| macros from gnulib. |
| (AC_LIB_LTDL): Latest libltdl is a sub-project with its own |
| configure.ac, so use AC_WITH_LTDL instead. |
| * Makefile.am (SUBDIRS): Add libltdl. |
| * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses |
| gl_INCLUDED_REGEX. |
| * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL. |
| (libm4_la_SOURCES): Remove ltdl.c and ltdl.h. |
| (libm4_la_LIBADD): Add LIBLTDL. |
| * m4/ltdl.c, m4/ltdl.h: Removed. |
| * m4/m4module.h: Include canonical ltdl.h. |
| * po/*.po: Updated. |
| |
| 2004-06-14 Gary V. Vaughan <gary@gnu.org> |
| |
| * gnulib/import: Now updates makefile fragments, and configure.ac. |
| * gnulib/m4/gnulib.am: New file. Generated makefile fragments. |
| * gnulib/m4/Makefile.am: include it. |
| * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4, |
| gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4, |

| gnulib/acm4/free.m4, gnulib/acm4/gettext.m4, |
| gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib |
| import. |
| * gnulib/m4/getopt_int.h: New source file from latest gnulib |
| import. |
| * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c, |
| gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c, |

| * commit: Updated from cvs-utils and tweaked for m4. |
| |
| 2003-12-01 Gary V. Vaughan <gary@gnu.org> |
| |
| * config/mkstamp: Updated from CVS libtool. |
| * configure.ac: Generate a gnu coding standards compliant version |
| number, and use it for the banner. |
| * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated |
| mhen the TIMESTAMP changes in ChangeLog, but the file modification |
| time doesn't (e.g. in cvs commit). Otherwise dist tarballs will |
| contain the previous version number. |
| * src/main.c: Make --version output conform to the GNU standard. |
| |
| * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g... |
| * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES, |
| m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES, |
| shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES, |
| time_la_SOURCES): ...so that these are defaulted correctly, and |
| can be removed from this file. |
| (AM_LDFLAGS): Add -module... |
| (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS, |
| traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS, |
| import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that |
| the individual settings can be removed. |
| * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once... |
| * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD, |
| m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD, |
| shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD, |
| time_la_LIBADD): ...so that these are picked up as a deplib of |
| libm4 and don't need to be set explicitly. |
| |
| 2003-11-18 Gary V. Vaughan <gary@gnu.org> |
| |
| * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la |
| from the standard build. It is too fragile. |
| |
| * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from |
| CVS libtool after merging m4 changes across to libtool. |
| |
| * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof. |
| * m4/path.c (search_path_add): Ditto. |
| |
| 2003-11-13 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for |
| libtool tags we don't use in configure. This reduces the size |
| of the script from over 1Mb to under 700Kb. |
| |
| 2003-11-13 Gary V. Vaughan <gary@gnu.org> |
| |
| The import script was not written properly, and the last gnulib |
| import was incomplete. Fixed that problem, and reimport our |
| gnulib dependencies, which picks up the address calculation |
| overflow checks described by Paul below. Also tweak the clients |
| of the gnulib xalloc module not to use deprecated macros: |
| |
| * gnulib/import: Recurse through module dependencies rather than |
| naively descending only one level. |
| * configure.ac: Add calls to gnulib's strnlen and extension module |
| macros. |
| * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and |
| extension modules. |
| * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4, |
| gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h, |
| gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h, |
| gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS |
| gnulib. |
| * gnulib/acm4/libtool.m4: Updated from CVS libtool. |
| * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in |
| place of `xcalloc (1, S)'. |
| * m4/m4.c (m4_create): Likewise. |
| * m4/m4private.h (m4_symbol_value_create): Likewise. |
| * m4/symtab.c (symtab_fetch): Likewise. |
| * m4/syntax.c (m4_syntax_create): Likewise. |
| * src/freeze.c (reload_frozen_state): Likewise. |
| * m4/path.c (search_path_add): Eliminate use of deprecated NEW |
| macro. |
| * m4/symtab.c (m4_symtab_create): Likewise. |
| |
| 2003-11-13 Gary V. Vaughan <gary@gnu.org> |
| |
| * tests/module.at: Comment typo. |
| |
| 2003-10-10 Gary V. Vaughan <gary@gnu.org> |
| |
| * tests/modules.at (modules: importing): Apply some lateral |
| thinking, and use AT_CHECK to compare the output of a sed pass |
| over stderr against the canonical strerror string. |
| |
| * tests/modules.at (modules: importing): Edit the generated stderr |
| output to canonicalize strerror output, before a comparison. |
| |
| 2003-10-10 Gary V. Vaughan <gary@gnu.org> |
| |
| Tru64UNIX perl is sloppy with namespace pollution. This patch is |
| careful not to trip over the mess: |
| |
| * modules/perl.c: Some builds of perl install headers that contain |
| `#define try __builtin_try'. Be sure to undefine that macro |
| before `m4/hash.h' gets included, which uses the `try' symbol. |
| * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and |
| `false' before including `stdbool.h'. |
| (DELETE): This symbol is not in m4's namespace, and is in any |
| case only used internally... |
| * m4/m4private.h (DELETE): ...so move it to here. |
| Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz> |

| 2003-10-08 Paul Eggert <eggert@twinsun.com> |
| |
| Don't use XMALLOC and XCALLOC. Once we install the |
| corresponding patch into gnulib, this will fix some |
| address-calculation overflow bugs on hosts where calloc (A, B) |
| returns garbage when A*B overflows. |
| |
| * m4/hash.c (m4_hash_new, node_new, m4_hash_resize, |
| maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with |
| xmalloc, XCALLOC with xcalloc. |
| * m4/m4.c (m4_create): Likewise. |
| * m4/m4private.h (m4_symbol_value_create): Likewise. |

| |
| 2003-09-16 Gary V. Vaughan <gary@gnu.org> |
| |
| * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import |

| * src/Makefile.am: Build it. |
| * src/main.c: Use it. |
| |
| * gnulib/m4/exit.h: Import exit module from CVS gnulib. |

| 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>, |
| Gary V. Vaughan <gary@gnu.org> |
| |
| * bootstrap: Separate options. |
| * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1. |
| * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is |
| not set. |
| * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD) |
| (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD) |
| (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD) |
| (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add |
| $(LTLIBINTL) for gettext support on cygwin. |
| * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now |
| have $(LTLIBINTL) from the preloaded module la files. |
| * README: Remove the warning about using --disable-nls on Windows |
| machines. |
| |
| 2003-09-15 Gary V. Vaughan <gary@gnu.org> |
| |
| * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler |
| picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c |
| is required. |
| |
| 2003-09-12 Gary V. Vaughan <gary@gnu.org> |
| |
| * doc/STYLE: Document the gnulib header naming conventions, and |
| #include policy. |
| * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h, |
| gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h, |
| gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h |
| respectively. |
| * gnulib/m4/Makefile.am: Remove the rules to build these headers. |
| |
| * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol |
| module from CVS gnulib. |
| * configure.ac (AC_REPLACE_FUNCS): Remove strtol. |
| (gl_FUNC_STRTOL): In favour of the module macro. |
| |
| 2003-09-12 Gary V. Vaughan <gary@gnu.org> |
| |
| Replace the getopt code with CVS gnulib getopt. The source files |
| detect whether they are in a glibc environment and preprocess away |
| all of the code if there is a system getopt, so we can compile |
| them into the m4 executable unconditionally: |
| |
| * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h, |
| gnulib/config/getopt.m4: Import getopt module from CVS gnulib. |
| * configure.ac (gl_GETOPT): Use this instead of homebrew inline |
| macros. |
| * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old |
| version. |
| * src/Makefile.am: Adjust. |
| * src/main.c: Always include our shipped getopt.h. |
| * po/POTFILES.in: Use new location of getopt.c. |
| |
| 2003-09-12 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.ac (AC_CONFIG_FILES): Remove config/Makefile. |
| * config/Makefile.am: Removed. Automake 1.8 distributes the files |
| in this directory automatically. |
| * Makefile.am (EXTRA_DIST): Except config/mkstamp. |
| |
| * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE |
| isn't set yet. |
| * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir |
| inline. |
| * modules/Makefile.am (pkglibexecdir): Set it here. |
| (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients. |
| |
| * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4: |
| Import regex module from CVS gnulib. |
| * gnulib/config/restrict.m4: Ditto for dependee module restrict. |
| * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but |
| do extra substitutions for Makefile. |
| * configure.ac: Use it. |
| * gnulib/m4/Makefile.am: Maybe install regex.h after linking it |
| from regex_.h if necessary. |
| * m4/system_.h: Include the correct version of regex.h. |
| * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy |
| version. |
| * po/POTFILES.in: Use new location of regex.c. |
| |
| * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and |
| realloc.c: automake distributes these files already. |
| |
| 2003-09-12 Gary V. Vaughan <gary@gnu.org> |
| |
| Replace the xstrzdup code by importing the xstrndup module from |
| CVS gnulib, along with its dependencies: strndup and strnlen: |
| |
| * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h, |
| gnulib/config/xstrndup.m4: Import xstrndup module from CVS |
| gnulib. |
| * gnulib/m4/strndup.c, gnulib/m4/strndup.h, |
| gnulib/config/strndup.m4: Ditto wrt strndup. |
| * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt |
| strnlen. |
| * gnulib/m4/Makefile.am: Add rules from newly imported modules. |
| However, contrary to gnulib, we install xstrndup.h. |
| * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup. |
| * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it |
| is an artifact of the old m4 portability layer. |
| * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent. |
| * m4/system_.h: Include xstrndup.h. |
| * m4/macro.c (process_macro): Call xstrndup, not xstrzdup. |
| |
| 2003-09-11 Gary V. Vaughan <gary@gnu.org> |
| |
| Reimport the latest xalloc module from CVS gnulib, and adjust the |
| m4 sources to take advantage of xalloc xfree. Also create a new |
| macro DELETE with the same semantics as the old m4 XFREE macro, |
| and carefully tweak callers: |
| |
| * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS |
| gnulib. |
| * m4/utility.c (xfree): Removed. This function is now supplied by |
| gnulib xalloc. |
| * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine. |
| * m4/path.c (search_path_add): Use NEW macro from xalloc.h. |
| * m4/symtab.c (m4_symtab_create): Ditto. |
| * m4/system_.h: Removed XFREE redefine. |
| (DELETE): New macro with same functionality as the original m4 |
| XFREE macro, but based on xalloc.h now. Changed all callers. |
| * src/main.c (main): Use XMALLOC macro. |
| * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree |
| instead of XFREE. |
| * m4/output.c (m4_output_exit): Use DELETE instead of XFREE. |
| |
| 2003-09-10 Gary V. Vaughan <gary@gnu.org> |
| |
| Import the xalloc module from CVS gnulib, along with its |
| dependencies: exitfail, malloc and realloc. We had different |
| semantics for our XFREE and a function xfree() not supplied by |
| gnulib, so also a bit of work to keep everything running |
| smoothly: |
| |
| * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup. |
| (gl_XALLOC): Use gnulib equivalents. |
| * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h, |
| gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib. |
| * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc. |
| * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt |
| realloc. |
| * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h, |
| gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc. |
| * gnulib/m4/Makefile.am: Add fragment from gnulib for newly |
| imported modules. |
| (pkgincdir): Removed. Use pkgincludedir instead. |
| * m4/m4private.h (XFREE): xfree already checks for NULL. |
| * m4/system_.h: Use xalloc module, and remove macros already |
| supplied by xalloc.h. |
| * m4/utility.c (xfree): xalloc does not yet implement xfree, so |
| moved the old definition from m4/xmalloc.c to here for now. |
| |
| 2003-09-09 Gary V. Vaughan <gary@gnu.org> |
| |
| Import the error and progname modules from CVS gnulib. Our old |
| error.c subsumed the functionality of both, so a little adjustment |
| was required to accomodate the split in sources. Also added more |
| wrapper macros to choose between a system installed error.h or our |
| shipped gnulib error module: |
| |
| * m4/error.c, m4/error.h: Removed. |
| * m4/Makefile.am: Adjust. |
| (pkgincdir): Removed. Use pkgincludedir instead. |
| * m4/module.h, src/main.c: Don't include `m4/error.h'. |
| * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable |
| error.h. |
| * gnulib/m4/progname.c: Imported from CVS gnulib. |
| * gnulib/m4/progname.h: Ditto. |
| * src/main.c: Adjust to use progname module. |
| * gnulib/m4/error.c: Imported from CVS gnulib. |
| * gnulib/m4/error_.h: Ditto. |
| * gnulib/m4/Makefile.am: Build the error module into our libgnu.la |
| if appropriate, and link a local error.h if the system version is |
| missing. |
| (libgnu_la_SOURCES) Add progname module sources. |
| * gnulib/config/error.m4: Imported from CVS gnulib. |
| * gnulib/config/strerror_r.m4: Ditto. |
| * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange |
| to have ERROR_H for Makefile substitutions and tell system.h |
| whether the system error.h should be used, or a locally installed |
| version. |
| * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR. |
| |
| 2003-09-09 Gary V. Vaughan <gary@gnu.org> |
| |
| * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo |
| s/gettext_.h/gettext.h/. |
| |
| * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and |
| automake have been fixed. |
| |
| * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap |
| gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits |
| of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here |
| rename to m4_OBSTACK in light of wrapping gl_OBSTACK. |
| |
| 2003-09-09 Gary V. Vaughan <gary@gnu.org> |
| |
| The gnulib obstack module requires the gnulib gettext module for |
| systems that do not have GNU gettext installed. Because we use |
| -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in |
| that directory incase it clashes with the system gettext.h. This |
| delta uses gettext_.h and extra rules in the Makefile to make a |
| link to gettext.h when needed: |
| |
| * Makefile.am (auxdir): Removed. No longer used. |
| * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used. |
| (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has |
| moved. |
| (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single |
| Makefile based build. |
| (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority |
| of the macros are kept. |
| * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first. |
| * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a. |
| * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a |
| distributes these automatically. |
| * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent |
| warning from automake-1.7a. |
| * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to |
| m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed |
| all callers. |
| * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto |
| wrt. m4_FUNC_OBSTACK. |
| * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto |
| wrt. m4_sys_STACKOVF. |
| * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto |
| wrt. _m4_LIB_GMP, m4_LIB_GMP. |
| (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's |
| namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp |
| respectively. |
| * config/m4-gettext.m4: New file to set GETTEXT_H appropriately. |
| * gnulib/m4/Makefile.am: Added a new block to make an appropriate |
| gettext.h link on deficient systems. |
| (pkginc_HEADERS): Mention $(GETTEXT_H). |
| (EXTRA_HEADERS): Mention gettext.h. |
| * gnulib/config/gettext_.h: New file from gnulib's gettext.h. |
| * gnulib/config/codeset.m4, gnulib/config/gettext.m4, |
| gnulib/config/glibc21.m4, gnulib/config/iconv.m4, |
| gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4, |
| gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4, |
| gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4, |
| gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4, |
| gnulib/config/lib-prefix.m4, gnulib/config/nls.m4, |
| gnulib/config/po.m4, gnulib/config/progtest.m4, |
| gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4, |
| gnulib/config/ulonglong.m4: Imported from CVS gnulib. |
| |
| 2003-09-05 Gary V. Vaughan <gary@gnu.org> |
| |
| We can't mirror the gnulib directory structure here, since we need |
| to be able to eg. `#include <m4/obstack.h>' from our source files, |
| which is much easier if the local obstack.h is created in a |
| directory named m4. Rather than trying to symlink everything into |
| the m4 directory, now we build a libtool convenience library from |
| the sources we get from gnulib and link that with libm4.la: |
| |
| * gnulib/config/extensions.m4: Imported from CVS gnulib. |
| * gnulib/config/unlocked-io.m4: Ditto. |
| * gnulib/m4/unlocked-io.h: Ditto. |
| * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4, |
| gnulib/m4/stdbool.m4: All moved to gnulib/config directory. |
| * gnulib/lib/obstack.c, gnulib/lib/obstack_.h, |
| gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory. |
| * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto. |
| * m4/Makefile.am: Adjust. |
| * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib |
| macros we redistribute. |
| * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience |
| library among others. |
| (GNULIB_SRCS, GNULIB_MACROS): Removed. |
| * Makefile.am (ACLOCAL_AMFLAGS): Adjust. |
| * config/m4-obstack.m4: Adjust. |
| * po/POTFILES.in: Adjust. |
| * configure.ac: Reformatting. Call newly imported gnulib macros. |
| * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed |
| bogus calls of `#include "m4.h"'. |
| * Makefile.am: INCLUDES has been deprecated in favour of |
| AM_CPPFLAGS. |
| * m4/Makefile.am: Ditto. |
| * modules/Makefile.am: Ditto. |
| * src/Makefile.am: Ditto. |
| |
| 2003-09-05 Gary V. Vaughan <gary@gnu.org> |
| |
| * config/Makefile.am: Reverting yesterdays patch for VPATH builds. |
| |
| 2003-09-04 Gary V. Vaughan <gary@gnu.org> |
| |
| Migrate the obstack support into the gnulib directories for easy |
| synchronisation with upstream files in gnulib: |
| |
| * config/gnu-obstack.m4: Moved from here... |
| * config/m4-obstack.m4: ...to here. |
| * config/Makefile.am (SPECIFIC_MACROS): Adjust. |
| * m4/obstack.c, m4/obstack_.h: Moved from here... |
| * gnulib/obstack.c, gnulib/obstack.h: ...to here. |
| * po/POTFILES.in: Adjust. |
| * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust. |
| * m4/Makefile.am: Add a whole new section to link the obstack |
| sources from the gnulib tree if necessary. |
| * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros |
| from gnulib. |
| * config/m4-obstack.m4: Rewrite as a wrapper for |
| gnulib/m4/obstack.m4. |
| |
| 2003-09-04 Gary V. Vaughan <gary@gnu.org> |
| |
| GNU M4 currently builds with a number of files adapted from |
| upstream sources. Recently the gnulib project on savannah.gnu.org |
| has pulled together a great many of these externally maintained |
| files. This delta is the beginnings of isolating those files |
| maintained in gnulib to make it easy to synchronise M4 with the |
| upstream files prior to releases. |
| |
| * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro |
| directory. |
| (SUBDIRS): Added new gnulib subdirectory. |
| * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles. |
| * config/stdbool.m4: Moved from here... |
| * gnulib/m4/stdbool.m4: ...to here. |
| * m4/stdbool_.h: Moved from here... |
| * gnulib/lib/stdbool_.h: ...to here. |
| * gnulib/Makefile.am: New file. Make sure the gnulib tree is |
| distributed. |
| * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based |
| code to work with new stdbool_.h location. |
| (gnulib_srcdir): New. |
| |
| 2003-09-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS) |
| (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH |
| builds to work. |
| (SPECIFIC_TOOLS): New variable. Moved mkstamp to here. |
| (EXTRA_DIST): Use it. |
| |
| * bootstrap: CVS autoreconf leaves file droppings. Remove |
| aclocal.m4t incase autoreconf doesn't. |
| |
| 2003-08-29 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with |
| the other gnulib imports, renamed to m4/obstack_.h. |
| * m4/obstack.c: Updated from CVS gnulib. |
| * m4/Makefile.am (EXTRA_HEADERS): Adjust. |
| * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional |
| header tests from gnulib obstack module. AC_CONFIG_LINKS knows |
| about vpath already, and $top_srcdir upsets CVS Automake, so the |
| $top_srcdir reference was removed. |
| |
| * m4/system-h.in: For consistency with the gnulib imports, renamed |
| to m4/system_.h. |
| * m4/Makefile (EXTRA_HEADERS): Adjust. |
| * configure.ac (AC_CONFIG_FILES): Adjust. |
| |
| * m4/stdbool_.h: New file from gnulib for systems without their |
| own. |
| * m4/Makefile.am: Add snippets from gnulib for C99 bool support. |
| * config/stdbool.m4: New file. Macros from gnulib for same. |
| * configure.ac: Use it. |
| |
| 2003-08-27 Gary V. Vaughan <gary@gnu.org> |
| |
| * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'` |
| * config/gmp.m4: Ditto. |
| * config/gnu-obstack.m4: Ditto. |
| * config/stackovf.m4: Ditto. |

| Still cleaning up the users' module API, by taking out the stuff |

| Libltdl already has an excellent mechanism for accessing C symbols |
| in modules. Lets use that! Remove all the exporting cruft and |
| just use lt_dlsym in conjunction with a few conventions to |
| simplify module writers' jobs. Also removed the table address |
| caching code and otherwise simplified the module loader quite a |
| bit. To access exported symbols in other modules, first the |
| exporting module must name the symbols <modname>_LTX_<symname>, |
| and the importing module must define a function type called |
| <symname>_func. The importer then adds |
| M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function |
| that wishes to call out to the exported functions. Care must be |
| taken that <symname> is non-NULL in the importing module incase |
| M4_MODULE_IMPORT fails, but otherwise it can be called as if the |
| definition was in the importers source. Study |
| `modules/{gnu.c,m4.{c,h}' for a model example. At the moment, |
| m4_module_import will attempt to automatically load a module |
| required for symbol access if it is not loaded already. |
| |
| * TODO: Removed the items fixed in this delta. |
| * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by |
| module name. |
| * m4/ltdl.h (lt_dlhandle_find): Declare it. |
| * m4/module.c (m4_module_unload): Use it. |
| * src/freeze.c (reload_frozen_state): Ditto. |
| * m4/m4module.h (m4_export): Deleted. Removed all references. |
| (M4_MODULE_IMPORT): New user convenience macro for importing |
| arbitrary symbols from other modules. |
| * m4/module.c (m4_module_import): New function to service |
| M4_MODULE_IMPORT macro. |
| (module_data): Removed. Looking up the tables on demand with |
| lt_dlsym, rather than caching their addresses here simplifies the |
| code substantially. |
| (m4_get_module_builtin_table, m4_get_module_macro_table): |
| Removed. Changed all callers. |
| (set_module_macro_table, set_module_builtin_table): Renamed to |
| install_macro_table and install_builtin_table respectively, and |
| simplified now that the cache is no more. |
| * modules/gnu.c (builtin_symbols): Use this new mechanism to |
| import m4_dump_symbols from the m4 module. |
| (builtin_esyscmd): Likewise for m4_set_sysval and |
| m4_sysval_flush. |
| * modules/m4.c (m4_export_table): Removed. Functions are |
| addressed with the new mechanism which doesn't need this. |
| (m4_set_sysval): New exported accessor function to prevent |
| problems with variable access on inferior architectures. |
| * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func) |
| (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so |
| that we can have some type safety. |
| * modules/modtest.c (export_test): C level exported function for |
| testing the new import mechanism. |
| * modules/import.c: New file for the import end of the test. |
| * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la. |
| * tests/modules.at: New test cases for intermodule symbol |
| importing. |

| Aside from auditing path.c for m4module.h api obfuscation, this |
| delta introduces the concept of private struct members in opaque |
| data types to GNU m4: See the STYLE file for details. |
| |
| * TODO: Remind ourselves that a rewrite of path.c is needed. |
| * m4/m4module.h (m4_search_path, struct m4_search_path_info): |
| Moved from here... |

| Changed all callers. |
| (dirpath): Moved functionality of this static declaration... |
| * m4/m4private.h (struct m4): ...to this new internal only |
| search_path field. Changed all callers. |
| (m4__get_search_path): Added new internal api accessor. |
| * m4/path.c (m4_search_path_info_new): Removed. Not used. |

| (m4_delete): Recycle search_path memory. |

| gone! |
| * doc/STYLE: Document convention for private fields in opaque |
| ADTs. |

| Sometimes exporting the address of a symbol from a module isn't |
| enough for other modules to call that symbol correctly. If |
| custom data types are used for function parameters, they need to |
| be known to the caller. This change introduces the concept of |
| $(prefix)/include/modules/$(modulename).h to declare those |
| structures. Also we move m4_dump_symbols from libm4 to the m4 |
| module to show this concept in action. |
| |
| * m4/m4module.h (m4_dump_symbol_data): Moved from here... |
| * modules/m4.h (m4_dump_symbol_data): ...to this new file for |
| exporting data structures from modules/m4.c. |
| * modules/m4.c, modules/gnu.c: Include it. |
| * modules/Makefile.am (pkgmodinc_HEADERS): Install it. |
| * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed |
| prototypes. |
| * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols): |
| Moved from here... |
| * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols): |
| ...to here, with slight renaming. |
| (m4_export_table): Prototype and add m4_dump_symbols. |
| * m4/symtab.c (m4_is_symbol_value_void): Needed for an external |
| definition of m4_dump_symbols. |
| * m4/m4module.h (m4_is_symbol_value_void): Prototype it. |
| * m4/m4private.h (m4_is_symbol_value_void): Fast macro version. |
| |
| 2003-07-24 Gary V. Vaughan <gary@gnu.org> |

| Create an export table in modules/m4.c in readiness for beefing up |

| * m4/debug.c (m4_debug_flush_files): Moved... |
| * modules/m4.c (m4_sysval_flush): ...to here and renamed. |
| * modules/gnu.c (builtin_esysval): Use it. |
| * m4/m4module.h (m4_export): New type for declaring module symbols |

| module for use by other modules. |
| |
| 2003-07-24 Gary V. Vaughan <gary@gnu.org> |
| |
| An experiment: There is loads of code in libm4 which should be in |
| the m4 module, but is also used by another module. Just because |
| some linkers won't cope with calls across dynamic runtime loaded |
| objects I initially left the code in libm4. It will tidy the |
| module api immensely if this code moves to the right place, I just |
| need to remember to invent a suitable calling mechanism at some |
| point. For now, only modules that are statically linked and |
| preloaded will get this treatment, so the only platforms that will |
| break are those that require all symbols to be resolved at link |
| time. |
| |
| * TODO: Reminder that what I am doing could reduce portability |
| unless I do something more robust later. |
| * m4/m4module.h (m4_sysval): No longer exported from libm4. |
| * m4/utility.c (m4_sysval): No longer declared in libm4. |
| * modules/Makefile.am: Reformatting. |
| * modules/m4.c (m4_sysval): Declare it at place of use. |

| |
| 2003-07-23 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/m4module.h: Reformatting and rearranging lines a bit. |

| |
| 2003-07-23 Gary V. Vaughan <gary@gnu.org> |

| (m4_get_debug_file, m4_get_trace_messages): New fast access macros |
| for the new fields. |

| functions, since they are only ever used from this file. Changed |
| all callers. |
| |
| 2003-07-17 Gary V. Vaughan <gary@gnu.org> |
| |
| Change the macros for checking syntax so that matching against |
| multiple possible syntax classes can be done with a single |

| Move the global variables that pertain to syntax to a new `struct |
| m4_syntax_table', and then add one of these to `struct m4'. The |
| ripple effect through the code to both change formerly global |
| references, and make sure a suitable context is available in |
| lexical scope is disproportionately large compared to the size of |
| the change proper. This change is a large part of decoupling |
| syntax.c from the rest of the code that uses it. |
| |
| * m4/m4private.h (struct m4): Add a syntax field. |
| * m4/m4.c (m4_create): Initialise it, |
| (m4_delete): Recycle it. |
| (m4_get_symtab): Remove hand coded version... |
| (m4_get_symbol_table): ...and generate this with cpp. Changed all |
| callers. |
| * m4/m4module.h (m4_context_field_table): Add an extra field so we |
| can generate m4_get_symbol_table. Add a new row for |
| m4_get_syntax_table. |
| (M4SYNTAX): Syntactic sugar for module writers. |
| (m4_symtab): Renamed to m4_symbol_table. Changed all callers. |
| (m4_syntax_table): New home for syntax related formerly global |
| variables. |
| * m4/m4private.h (struct m4_syntax_table): Define it. |
| * m4/input.c (m4_input_init): Initialisation of these formerly |
| global variables moved... |
| * m4/syntax.c (m4_syntax_create): ...to here. |
| * m4/input.c (m4_input_exit): And similarly, recycling of the |
| memory used by those values moved... |
| * m4/syntax.c (m4_syntax_delete): ...to here. |
| * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM): |

| global equivalents. |
| (m4__single_quotes, m4__single_comments, m4__use_macro_escape): |
| Removed and incorporated into m4_syntax_table structure. |
| * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto. |
| * m4/syntax.c (m4_set_syntax): Now returns an error status, |
| instead of requiring a `struct m4' to generate its own errors. |
| Changed all callers. |
| * src/main.c (main): Now that the syntax table is initialised as |
| part of m4_create, we have to manually wipe the syntax entries if |
| we are about to read a frozen file. |

| |
| * m4/hash.c (m4_hash_resize): ifdefed out. This function is |

| Two related changes, and a huge knockon effect throughout the |
| source: Moved the option variables out of global space and into |
| `struct m4'; made `m4_symtab' a real datatype, so that its api |
| is not marred passing `struct m4' around just so it can decide |
| whether to keep traced symbol names or not. Added setters and |
| getters for the formerly global option variables, and obviously |
| changed a vast number of functions to take a `struct m4' and use |
| the getter funcs to find option values. |
| |
| * m4/utility.c (interactive, sync_output, debug_level) |
| (no_gnu_extensions, prefix_all_builtins, suppress_warnings) |
| (max_debug_argument_length, warning_status, nesting_limit) |
| (discard_comments): Removed. |
| * m4/m4module (warning_status, no_gnu_extensions, nesting_limit) |
| (debug_level, max_debug_argument_length, prefix_all_builtins) |
| (suppress_warnings, discard_comments, interactive, sync_output): |
| Removed from here... |
| * m4/m4private.h (struct m4): ...and equivalent fields added to |
| this structure. |
| (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt) |
| (m4_get_nesting_limit_opt, m4_get_debug_level_opt) |
| (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt) |
| (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt) |
| (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access |
| macros for the new fields. |
| * m4/m4module.h (m4_context_field_table) |
| (m4_context_opt_bit_table): Helper macros used to generate |
| prototypes, setters and getters for new option fields |
| consistently. |
| * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt) |
| (m4_get_nesting_limit_opt, m4_get_debug_level_opt) |
| (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt) |
| (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt) |
| (m4_get_interactive_opt, m4_get_sync_output_opt) |
| (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt) |
| (m4_set_nesting_limit_opt, m4_set_debug_level_opt) |
| (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt) |
| (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt) |
| (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable |
| setter and getter functions generated by cpp from |
| m4_context_field_table and m4_context_opt_bit_table, exported as |
| part of the module api. Changed all callers. |
| * m4/symtab (struct m4_symtab): Used as the concrete type for |
| m4_symtab now. |
| (m4_symtab_create): Allocate and initialise a new struct. |
| (m4_symtab_apply): New function that works like m4_hash_apply, but |
| with different callbacks specific to symbol tables. Changed all |
| callers. |
| (symbol_destroy, arg_destroy, arg_copy): Renamed |
| symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that |
| they have unused parameters for a reason! |
| (dump_symbol_CB): New callback to dump the contents of a single |
| symbol. |
| (symtob_dump): Rewritten in terms of dump_symbol_CB. |
| * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB. |
| Changed all callers. |
| * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field |
| of the contained `m4_symtab' at the `no_gnu_extensions' field. |
| Although I'm not convinced these semantics are correct, they are |
| at least consistent with how things were before this delta. Also |
| set the default nesting limit to M4_DEFAULT_NESTING_LIMIT. |
| |
| 2003-06-19 Gary V. Vaughan <gary@gnu.org> |
| |
| Tie down the interface to libm4 some more. Make more structures |
| opaque to modules by moving them to m4private.h, and writing |
| setters and getters. To win back the speed penalty for doing this |
| also wrote macroized versions that do know about structure layout |
| in m4private.h and #include that file into modules when NDEBUG is |
| defined at compile time. There are still some accessor macros in |
| m4private.h that need to go, but that is not necessary to clean |
| the module api up. |
| |
| * m4/m4module.h (m4_symbol_type): Moved... |
| * m4/m4private.h (m4__symbol_type): ...to here. |
| * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced) |
| (m4_set_symbol_traced, m4_set_symbol_name_traced) |
| (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text) |
| (m4_get_symbol_func, m4_symbol_value_create) |
| (m4_symbol_value_delete, m4_set_symbol_value_text) |
| (m4_set_symbol_value_func): New exported api to symbols. |
| (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text |
| and m4_is_symbol_value_func. |
| * m4/m4module.h: Prototype these guys. |
| * m4/module.c (m4_set_module_macro_table) |
| (m4_set_module_builtin_table): Make these static, there is no |
| reason to pollute the api with them. |
| * m4/m4private.h: Reformatting. |
| (m4_get_symtab): Only define when NDEBUG is defined. |
| (m4_get_symbol_value, m4_get_symbol_traced) |
| (m4_set_symbol_traced, m4_set_symbol_name_traced) |
| (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text) |
| (m4_get_symbol_func, m4_symbol_value_create) |
| (m4_symbol_value_delete, m4_set_symbol_value_text) |
| (m4_set_symbol_value_func): Macro implementations of the new |
| functions when NDEBUG is defined. |
| (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT) |
| (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed. |
| Superceded by the above. All callers changed. |
| (M4ARG): Removed. This is no longer different to the |
| m4/m4module.h definition. |
| * modules/gnu.c, modules/m4.c: Only include m4private.h when |
| NDEBUG is defined. That way we exercise the same (albeit slower) |
| api that external modules must use. |
| |
| 2003-06-18 Gary V. Vaughan <gary@gnu.org> |
| |
| Renamed some of the types and their accessors to make more sense. |
| Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL |
| has a stack of SYMBOL_VALUEs. |
| |
| * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text) |
| (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value, |
| m4_get_symbol_value_type, m4_get_symbol_value_text, |
| m4_get_symbol_value_func and m4_symbol_value_copy respectively. |
| Changed all callers. |
| (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/ |
| (m4_get_token_type): Renamed |
| * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved |
| to the internal api. |
| * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/ |
| s/TOKEN_/VALUE_/ |
| (m4__symtab_init, m4__symtab_exit): Removed prototypes. |
| (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers. |
| (m4__token_type): Moved here from m4module.h. |
| (m4__next_token): Renamed from m4_next_token. |
| * m4/symtab.c: Removed some of the parameterised macro support |
| functions for modularisation later. |
| (m4_token_copy): Renamed to m4_symbol_value_copy, and use new |
| m4_hash_dup to perform a true deep copy of the SRC. |
| (arg_copy): Callback for m4_symbol_value_copy. |
| * utility.c (m4_token_get_type, m4_token_text, m4_token_func): |
| Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and |
| m4_get_symbol_value_func. Changed all callers. |
| |
| 2003-06-18 Gary V. Vaughan <gary@gnu.org> |
| |
| Tidy up style of hash.[ch] in accordance with doc/STYLE. |
| |
| * m4/hash.c: Internal symbol renaming and formatting. |
| (m4_hash_dup): New function to facilitate deep copies of hash |
| tables. |
| (m4_hash_apply_func): Returns a void* now, which is a richer type |
| for returning exceptions (NULL means keep going). |
| (m4_hash_apply): Ditto. |
| * m4/hash.h: Declare exported symbols with an explicit extern. |
| Reformated. |
| |
| 2003-06-17 Gary V. Vaughan <gary@gnu.org> |
| |
| Still refactoring furiously. This delta represents a change in |
| semantics to symtab.c. Instead of building temporary m4_tokens |
| in the caller, and copying fields in the methods, we now create |
| the actual m4_token for hashing in the caller so the methods just |
| slot them in directly. Also, this means that we don't lookup a |
| symbol and get back an allocated but VOID token to copy fields |
| into, we create the token we want to push and pass that to |
| m4_symbol_define or m4_symbol_pushdef. And that's it. There are |
| a few other small changes to stop knowledge of the implementation |
| of symtab.c leaking out into other files. |
| |
| * m4/macro.c (expand_argument): Comment typo corrected. |
| * m4/symtab.c (symtab_fetch): New function to fetch the address of |
| an interned symbol. |
| (m4_symbol_pushdef): Take an extra value parameter and use this |
| directly as the new top of the value stack. All callers changed |
| to build a token and pass responsibility for memory in, rather |
| than copying as we used to. |
| (m4_symbol_define): Also use the new value parameter directly as a |
| replacement for the top of the value stack. All callers changed |
| to build a token as above. |
| (m4_set_symbol_traced): New function to set the traced bit on the |
| named symbol, creating it if necessary. |
| (symbol_popval): The guts of the old m4_symbol_popdef. |
| (m4_symbol_popdef): Use it. |
| * m4/builtin.c (m4_symbol_set_token): Removed, |
| (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and |
| replaced... |
| * m4/module.c (m4_set_module_builtin_table) |
| (m4_set_module_macro_table): ...with these more orthogonal |
| functions. |
| * m4/m4module.h (m4_macro_pushdef, m4_macro_define) |
| (m4_builtin_pushdef, m4_builtin_define): Removed. No longer |
| required. |
| * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE) |
| (m4_arg_signature_parse): Moved... |
| * m4/symtab.c: ...to here. |
| * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't |
| screw something up. Moved... |
| * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it |
| actually does a proper deep copy of source to dest. |
| |
| 2003-06-16 Gary V. Vaughan <gary@gnu.org> |
| |
| Further refactoring to stabilise the module API. Renaming some |
| functions for orthogonality, and judicious definition migration to |
| move things out of the set of exported symbols. |
| |
| * doc/STYLE: New file. Notes on coding style. |
| * m4/m4module.c: Updated bitrotted docucomment at the top of the |
| file. |
| (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to |
| m4_get_module_name, m4_get_module_builtin_table, |
| m4_get_module_macro_table which are verb phrases. Changed all |
| callers. |
| * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install): |
| Moved to... |
| * m4/module.c (m4_set_module_builtin_table) |
| (m4_set_module_macro_table): ...here, and renamed. Changed all |
| callers. |
| * m4/m4module.c (m4_module_data): This... |
| * m4/m4private.c (struct m4_module_data): ...and this... |
| * m4/module.c (module_data) ...consolidated here and no longer |
| exported. Changed all callers. |
| |
| 2003-06-16 Gary V. Vaughan <gary@gnu.org> |
| |
| Begin work on lifting the curse of the global variables. To start |
| with create a `struct m4' context container, and replace |
| `m4__symtab' with `context->symtab' throughout. This means |
| initialising a context container in main, and adjusting many |
| functions between main and the module entry points so that the |
| container gets passed through. It would have been nice to |
| defer this until after 1.5, but it has a major effect on the |
| user's module writing ABI, so it needs to be addressed now - at |
| least in the areas that impact the ABI. An interrelated change |
| in the symtab API removes the dependency on a global symbol table, |
| and instead focuses on a passed table (from the context |
| container). |
| |
| * TODO: Reminders for finishing context functionality. |
| * m4/Makefile.am (libm4_la_SOURCES): Add m4.c. |
| * m4/m4.c: New file. Manage new struct m4 objects to eliminate |
| global variables and eventually allow m4 to be reentrant. |
| * m4/m4private.h (m4): Define the new structure here... |
| (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that |
| don't carry the overhead of a function call. |
| * m4/m4module.h: Prototype extern functions from m4/m4.c. |
| (m4): Declare type for new struct m4 objects. |
| (M4SYMTAB): User macro to ease finding the symbol table for the |
| current context for module developers. |
| (m4_symbol_token): Renamed to m4_symbol_set_token which contains a |
| verb. |
| (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER) |
| (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install) |
| (m4_call_macro, m4_dump_symbols, m4_expand_input) |
| (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define) |
| (m4_macro_pushdef, m4_macro_table_install, m4_module_load) |
| (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an |
| m4* context parameter. Changed definitions and all callers. |
| (m4_symtab): Alias for m4_hash to decouple the |
| m4_symtab api from m4_hash. |
| (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of |
| m4_hash. |
| (m4_symtab_create): New function to return an initialised |
| m4_symtab. |
| (m4_symtab_delete): New function to delete an m4_symtab's memory. |
| (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup) |
| (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter |
| instead of simply using the global m4__symtab. Changed |
| definitions and all callers. |
| * m4/m4private.h (m4__symtab_remove_module_references): Ditto. |
| * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed. |
| * src/main.c (main): Create a context and use that instead of the |
| former global m4__symtab. |
| |
| 2003-06-13 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter |
| to the callback. Callbacks should not need to hardcode the |
| hashtable they are working from, nor should we have to waste the |
| userdata parameter to pass the table in. |
| * m4/hash.h (m4_hash_apply_func): Require the initial table |
| parameter. |
| * m4/symtab.c (symtab_destroy): Use the passed table instead |
| of hardcoding m4__symtab. |
| (m4_symbol_popdef): Don't use the userdata parameter to pass the |
| table to arg_destroy. |
| (arg_destroy): Use the hash parameter, ignore userdata. |
| * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func |
| prototype. |
| (traceon, traceoff): Call set_trace with the extra initial |
| parameter. |
| |
| 2003-06-13 Gary V. Vaughan <gary@gnu.org> |
| |
| More refactoring to stabilise the module api, this time for |
| symtab.c. Additionally, start to pay attention to function names |
| that don't contain a verb like they should. |
| |
| * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a |
| wrapper for m4_hash_apply to decouple the symtab module from the |
| hash module. |
| (m4_symbol_builtin, m4_symbol_macro): Renamed to |
| m4__symbol_set_builtin and m4__symbol_set_macro. Changed all |
| callers. |
| (m4_symbol_delete): Create a macro version to save a function |
| call. |
| (m4_token_t, m4_data_t): These violate the POSIX reserved |
| namespace. Renamed to m4_token_type and m4_symbol_type. Changed |
| all callers. |
| (m4_token_type): Renamed to m4_token_get_type. |
| (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references) |
| (m4_symtab_exit): Removed from the exported module |
| api... |
| * m4/m4private.h (m4__symtab, m4__symtab_init) |
| (m4__symtab_remove_module_references, m4__symtab_exit): ...and |
| renamed and added to the internal api. Changed all callers. |
| (m4_symtab_apply): A faster macro version of the function for |
| users of the internal api. |
| * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to |
| symbol_destroy and arg_destroy. |
| (symtab_debug): Added a prototype. |
| (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file |
| so that callers in this file get the faster macro versions from |
| m4/m4private.h. |
| |
| 2003-06-12 Gary V. Vaughan <gary@gnu.org> |
| |
| Refactoring modules to rationalise the API into an external |
| documented (eventually!) API for use by modules in the `m4_' |
| namespace declared in m4/m4module.h, an internal API between the |
| source files we ship (including our shipped modules) in the `m4__' |
| namespace declared in m4/m4private.h and making the rest as |
| cohesive as possible with liberal use of the `static' keyword. |
| This change represents an audit to m4/module.c along these |
| guidelines. |
| |
| * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin): |
| Removed. No longer used. |
| (m4_module_close): Removed prototypes. |
| (m4_module_init, m4_module_open, m4_module_unload_all): Removed |
| from the exported module api... |
| * m4/m4private.h (m4__module_init, m4__module_open) |
| (m4__module_exit): ...and renamed and added to the internal api. |
| Changed all callers. |
| (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL): |
| Centralised definitions after renaming... |
| * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL) |
| (M4_FINISH_SYMBOL): ...and removing from here. |
| (m4_module_dlerror, m4_module_remove, m4_module_close) |
| (m4_caller_id): Not exported at all, so renamed to module_dlerror, |
| module_remove, module_close and caller_id. |
| (MODULE_SELF_NAME): New macro to make reporting self errors |
| easier. |
| (m4_module_load, module_close, module_remove): Use it. |
| * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH" |
| name. |
| * src/main.c (main): Use it. |
| |
| 2003-06-12 Gary V. Vaughan <gary@gnu.org> |
| |
| * README: Remove references to --enable-changeword, which has been |
| removed from the code. |
| |
| 2003-06-11 Gary V. Vaughan <gary@gnu.org> |
| |
| Getting rid of the annoying bug with configure --enable-debug, |
| which spewed -e: command not found errors. This was an interaction |
| between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4. |
| You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or |
| branch-1-5) to get the full fix. |
| |
| * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version |
| of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED), |
| and then use the probed value of $SED. |
| (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define |
| this, it messes up the AC_REQUIRE stack. |
| |
| 2003-06-10 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to |
| the destroy callback. |
| (m4_arg_destroy): Use the hash address to free the hash node key |
| field. |
| |
| 2003-06-06 Gary V. Vaughan <gary@gnu.org> |
| |
| First cut at formal parameters in macros. |
| |
| * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup. |
| * m4/xstrzdup.c: New file. |
| * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for |
| associative array of parameter names to details. |
| (m4_symbol_token): Capture macro names with parameter lists. |
| (m4_arg_signature_parse): And build an associative array to hang |
| from the symbol structure to map names to details. |
| * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by |
| m4_hash_resize idiom. Now that we potentially add a little hash |
| table to many of the entries in the symbol table, added an extra |
| arg to set the initial size. Changed all callers. |
| (m4_hash_apply): New function that is basically a generalised |
| version of... |
| * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted |
| all callers to call m4_hash_apply instead. |
| (m4_arg_destroy): Recycle memory used by an m4_token_arg. |
| (m4_symbol_popdef): Use m4_arg_destroy to help recycle the |
| m4_arg_signature association that might be attached to the symbol, |
| * m4/hash.h (m4_hash_apply_func): Replacement type for... |
| * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted. |
| (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in |
| parameter lists. |
| (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax. |
| (M4_IS_IDENT): Detect characters that can be safely used in |
| parameter names. |
| * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character. |
| * m4/macro.c: Corrected grammar in some comments. Use `token' |
| rather than `td' for m4_token variables. |
| (m4_process_macro): If we find a dollar followed by some |
| M4_IS_IDENT characters, replace that with the contents of the argv |
| entry with offset stored in the m4_token_arg associated with the |
| collected identifier. |
| |
| 2003-06-05 Gary V. Vaughan <gary@gnu.org> |
| |
| Begin preparations for supporting formal parameters in m4 macros. |
| |
| * m4/m4private.h (struct m4_token_arg): Placeholder for holding |
| the details of a formal parameter. |
| (m4_token): Add an arg_signature member to hold a hash table for |
| looking up formal parameters. |
| * m4/input.c: Update more bitrotted comments. |
| (m4_push_builtin): Initialise arg_signature member. |
| (init_builtin_token): Copy arg_signature member. |
| * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define) |
| (m4_macro_pushdef, m4_macro_define): Rewritten as macros to |
| replace... |
| * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define) |
| (m4_macro_pushdef, m4_macro_define): ...these, And... |
| (m4_symbol_token): ...wrapped around this new function, which |
| vastly simplifies the arguments required by the functions it |
| replaces. |
| Changed all callers. |
| |
| 2003-06-05 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/macro.c: Format changes. |
| |
| 2003-06-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/input.c: Updated various bitrotted comments. |
| (m4_push_builtin): Just pass the whole m4_token, rather than |
| extracting all the fields in the caller. This also allows us to |
| check the token type for consistency. |
| (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO): |
| Renamed to builtin_funcs, builtin_peek, builtin_read, |
| m4_push_builtin and CHAR_BUILTIN for consistency with the rest of |
| the code. Changed all callers. |
| (struct input_block): Similarly renamed u_m member to u_b, and |
| changed all callers. |
| (m4_next_token): Use bzero to initialise the data fields. |
| * m4/m4module (m4_push_macro): Renamed to m4_push_builtin. |

| 2003-05-29 Gary V. Vaughan <gary@gnu.org> |
| |
| These changes were necessary to get m4 to build on my iBook |
| running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc |
| (GCC) 3.1 20020420 (prerelease)": |
| |
| * src/main.c: Don't include dlfcn.h, ltdl.h handles correct |
| inclusion of module loader headers. |
| * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS. |
| * m4/Makefile.am: Ditto. |
| (libm4_la_LIBADD): Added $(LTLIBINTL). |

| the one already in error.c! |
| * m4/m4module.h (program_name): Define to program_invocation_name |
| when using GNU C library. Use an explicit extern declaration. |

| 2002-11-04 Akim Demaille <akim@epita.fr> |
| |
| * doc/m4.texinfo (Esyscmd): Don't grep, use something easier: |
| running m4 itself. |
| * tests/others.at (iso8859): Use abs_srcdir, not srcdir. |
| |
| 2002-11-04 Akim Demaille <akim@epita.fr> |
| |

| |
| 2002-11-04 Akim Demaille <akim@epita.fr> |
| |
| * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5, |
| used as `external', and Libtool 1.4.3. |
| (LINGUAS): Remove. |
| (LTLIBOBJS): Don't play with it. |
| * intl/: Remove. |
| * Makefile.am (SUBDIRS): Remove intl. |
| (ACLOCAL_AMFLAGS): Add -I config. |
| (EXTRA_DIST): Add config/config.rpath. |
| * po/LINGUAS: New. |

| |
| 2002-05-29 Gary V. Vaughan <gary@gnu.org> |
| |
| Preparations for refactoring syntax tables to allow reverse |
| lookups [fetch me a M4_SYNTAX_OPEN], without compromising the |
| speed of normal lookups in an array of unsigned short. |
| |
| * m4/input.c (single_quotes, single_comments, use_macro_escape): |
| Moved from here... |
| * m4/m4private.h (m4__single_quotes, m4__single_comments, |
| m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix |
| is for internal symbols which unavoidably pollute the global |
| namespace, but are not published APIs. |
| Adjusted all callers. |
| * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes, |
| m4_set_comment, m4_set_syntax, set_syntax_internal, |
| unset_syntax_attribute): Moved from this file... |
| * m4/syntax.c: New. ...to this file. |
| Also added an m4_syntax_exit stub for orthogonality. |
| * src/main.c (main): Use it. |
| * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c. |
| * m4/m4module.h: Reformatting. New prototypes. |
| |
| 2002-05-29 Gary V. Vaughan <gary@gnu.org> |
| |
| * bootstrap (aclocal_apiversion): The aclocal apiversion is |
| distinct from the automake release number (in that the apiversion |
| apparently has no micro-version-component). |
| (aclocal_apilibdir): Use it. |
| |
| 2002-05-28 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/hash.c (m4_hash_resize): New function. |
| * m4/hash.h: Add prototype. |
| * m4/symtab.c (m4_symtab_init): Use it. This could do with some |
| benchmarking to find a good value for, say, autoconf. This is |
| already a little quicker than before for me. |
| |
| * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here... |
| * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here, |
| and reenamed. |
| * m4/hash.h: Adjust prototypes. |
| |
| 2002-01-22 Akim Demaille <akim@epita.fr> |
| |
| * bootstrap (aclocal_apilibdir): New, to cope with Automake's new |
| APIVERSION scheme. |
| * tests/Makefile.am (package.m4): New. |
| * tests/atlocal.in: Adjust to CVS Autotest. |
| * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ. |
| * configure.ac: LIBOBJ is a forbidden string. |
| Simplify AM_INIT_AUTOMAKE invocation. |
| * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and |
| options.m4. |
| |
| 2002-01-21 gettextize <bug-gnu-utils@gnu.org> |
| |
| * po/Makefile.in.in: Upgrade to gettext-0.10.40. |
| |
| 2001-10-19 Akim Demaille <akim@epita.fr> |
| |
| * m4/module.c, m4/output.c, src/main.c: Normalize error messages. |
| |
| 2001-10-19 Akim Demaille <akim@epita.fr> |
| |
| * m4/input.c (m4_next_token): Display where was opened what is |
| not closed. |
| |
| 2001-10-19 Akim Demaille <akim@epita.fr> |
| |
| * m4/macro.c (expand_argument): Display where was opened what is |
| not closed. |
| |
| 2001-10-18 Akim Demaille <akim@epita.fr> |
| |
| * m4/input.c, modules/m4.c: Formatting changes. |
| |
| 2001-10-17 Gary V. Vaughan <gary@gnu.org> |
| |
| * bootstrap: s/configure.in/configure.ac/ |
| |
| 2001-10-16 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/symtab.c (m4_symbol_destroy): This function calls |
| m4_symbol_popdef, which recycles a symbols memory when the last |
| definition is popped. Since we were passing the address of the |
| symbol name found in the symbol table, and it was being removed |
| partway through m4_symbol_destroy() we were referencing freed |
| memory for the balance of the function. Now we take a copy of the |
| symbol name tring and use that as a key into the symbol |
| table... that way if the original symbol name is freed, the copy |
| is still valid. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * m4/ltdl.c: Update. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c: |
| Don't gettextize internal error messages. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * tests/macros.at (Arity and defn): New failing test. |
| (Arity, defn, and freeze): New. |
| |
| Fix `Arity and defn'. |
| |
| * m4/input.c (m4_push_macro): Don't forget the arity. |
| * modules/m4.c (defn): Likewise. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move |
| to... |
| * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers) |
| (Propagation of traceon, Propagation of --trace): this new file. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...) |
| interface instead of (name, argc...). |
| Upon failure, specify which argument was guilty. |
| Adjust callers. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * modules/evalparse.c: Save translators' time: don't translate |
| internal error messages. |
| (m4_evaluate): Simplify/normalize error messages. |
| * doc/m4.texinfo (Eval): Adjust. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases |
| where no checking is needed. |
| * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...) |
| interface instead of (name, argc...). |
| Adjust callers. |
| * modules/gnu.c (m4_patsubst_do): Don't check argc, done |
| elsewhere. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * m4/utility.c (m4_bad_argc): Display user argument counts, i.e., |
| exclude the builtin name from the count. |
| * modules/m4.c (ifelse): Do not use the regular argc mechanism, as |
| calling ifelse with a single argument is valid. |
| * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked |
| with 1 and 2 args, mostly to strengthen the test suite. |
| |
| 2001-10-13 Akim Demaille <akim@epita.fr> |
| |
| * m4/output.c (m4_make_diversion, m4_insert_file) |
| (m4_insert_diversion, +m4_freeze_diversions): Ansify. |
| |
| 2001-10-12 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/input.c (init_builtin_token): Renamed from init_macro_token, |
| since we call these things builtins in the rest of the code! |
| |
| * modules/gnu.c (m4_regexp_compile): s/%0/%s/ |
| |
| 2001-10-12 Gary V. Vaughan <gary@gnu.org> |
| |
| Rather than forcing each builtin definition to manage its own |
| argument range checking, tabulate the maxima and minima for all |
| builtins in each module. This forces us to consider what the |
| valid ranges for each builtin should be, and moves the checking |
| code out of each builtin implementation and into the builtin |
| caller infrastructure. |
| |
| * m4/m4module.h (struct m4_builtin): Add argument minima and |
| maxima. |
| * m4/m4private.h (struct m4_token): Reflect them here too. |
| * m4/input.c (struct input_block): ...and here. |
| (m4_token_copy): New function for token copying. |
| (init_macro_token): Copy them from a token to the input stack. |
| (m4_next_token): Don't forget to initialise them for text |
| macros. |
| * m4/macro.c (expand_argument): Use m4_token_copy, and also |
| check argument counts before calling the builtin handler. |
| * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params. |
| (m4_symbol_macro): Likewise. |
| * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args |
| parameters. Updated all callers. |
| (m4_builtin_define): Ditto. |
| (m4_macro_pushdef, m4_macro_define): Ditto. |
| * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto. |
| * modules/evalparse.c: Declare argument counts for defined |
| builtins and remove explicit calls to m4_bad_argc(). |
| * modules/gnu.c: Ditto. |
| * modules/load.c: Ditto. |
| * modules/m4.c: Ditto. |
| * modules/modtest.c: Ditto. |
| * modules/mpeval.c: Ditto. |
| * modules/perl.c: Ditto. |
| * modules/shadow.c: Ditto. |
| * modules/stdlib.c: Ditto. |
| * modules/time.c: Ditto. |
| * TODO: Updated. |

| |
| The trace semantics now attach the trace bit to a symbol name. |
| For as long as a traceon(`foo') is active, calls to foo will be |
| traced regardless of intervening undefines or module unloads. |
| Fixed the flag propogation issues differently to the fixes |
| reverted with the last attempt at nailing down trace: |
| |
| * m4/m4private.h: This file is not visible outside of the m4 |
| source tree, so I removed all the `M4_' and `m4_' prefixes to save |
| on typing. Updated all clients. |
| (m4_token): New typedef contains the fields that need to be passed |
| around with the low level tokeniser. |
| (m4_token_data): Removed. |
| (m4_symbol): Now contains the traced flag again. |
| * m4/symtab.c: Rewritten again. Now we don't remove symbols with |
| the trace bit set. This change is contained entirely within this |
| module and doesn't leak out into the callers. Updated all |
| clients. |
| (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the |
| new fields in m4_token. Updated all clients. |
| * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so |
| that `groks_macro_args' and `blind_if_no_args' flags are retained |
| when defn() results are passed around in m4 code. Updated all |
| callers. |
| (m4_builtin_define): Ditto. |
| (m4_macro_pushdef, m4_macro_define): Ditto. |
| * m4/input.c (struct input_block): Add a flags field to facilitate |
| the above. |
| (m4_push_macro): ...use it. |
| (init_macro_token): Retrieve it. |
| (m4_next_token): Initialise it. |
| * m4/macro.c (expand_argument): Copy it. |
| * m4/m4module.h: Adjust. |
| * tests/builtins.at: Adjust the expected output of the trace |
| tests to reflect the change in semantics. |
| * tests/modules.at (modules: trace): Check that unloading a |
| module which supplies a traced symbol definition doesn't lose te |
| trace bit. |
| |
| 2001-10-07 Gary V. Vaughan <gary@gnu.org> |
| |
| * modules/gnu.c (m4_macro_table): Display the timetamp when |
| expanding __m4_version__. |
| |
| * configure.ac (--with-modules): Forgot a comma in the |
| AC_HELP_STRING parameter list. |
| |
| 2001-10-05 Gary V. Vaughan <gary@gnu.org> |
| |
| * bootstrap: Remove aclocal.m4t when it is no longer required. |
| |
| 2001-10-05 Akim Demaille <akim@epita.fr> |
| |
| * tests/Makefile.am: Adjust for gnuprog2. |
| * tests/m4.in: There can be a leading path. |
| * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5. |
| * tests/testsuite.at: Adjust to the most recent Autotest. |
| (AT_CHECK_M4_FILTER): Fix and rename as... |
| (AT_TEST_M4): this. |
| * tests/others.at: Use it. |
| |
| * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a |
| variable in shell scripts, one uses `$'... |
| |
| 2001-10-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.ac: `rm -f $m4_getopt_h' was lost. |
| |
| 2001-10-04 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.ac (TIMESTAMP): Display with AS_BOX at configure |
| time. Define it for config.h in order to... |
| * src/main.c (main): ...display the timestamp for --version. |
| |
| 2001-10-04 Akim Demaille <akim@epita.fr> |
| |
| * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from |
| previous builtins `regexp' and `patsubst'. |
| (regexp, patsubst): Use them. |
| (eregexp, epatsubst): New builtins. |
| * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as... |
| (Epatsubst and Patsubst, Eregexp and Regexp): these. |
| (Extensions): More info on REs. |
| |
| 2001-10-04 Akim Demaille <akim@epita.fr> |
| |
| * modules/modtest.c (init_handler): Consistently output to stderr. |
| (finish_handler): New. |
| (test): The `if' is an `assert'. |
| * tests/modules.at: Adjust. |
| |
| 2001-10-04 Akim Demaille <akim@epita.fr> |
| |
| * m4/utility.c (m4_bad_argc): Detail the mismatches. |
| |
| 2001-10-01 Akim Demaille <akim@epita.fr> |
| |
| * tests/generate.awk: Tag the tests with `documentation'. |
| * tests/modules.at (AT_CHECK_M4_MODTEST): New. |
| Use the make the existing modtest tests more uniform, and complete |
| the set of possibilities. |
| |
| 2001-10-01 Akim Demaille <akim@epita.fr> |
| |
| * config/gmp.m4: Consult the user before using GMP: use |
| --without-gmp. |
| * configure.ac: Adjust. |
| * modules/gmp.c: No protection needed as the module is not built |
| if GMP is not used. |
| |
| 2001-10-01 Akim Demaille <akim@epita.fr> |
| |
| * tests/generate.awk: Remove debugging code. |
| (fatal): Specify the current location. |
| |
| * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c, |
| * modules/gnu.c, modules/m4.c: Use M4ARG. |
| |
| 2001-10-01 Akim Demaille <akim@epita.fr> |
| |
| * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New. |
| (m4_regexp_compile): New. |
| (regexp, patsubst): Use it. |
| |
| 2001-09-30 Gary V. Vaughan <gary@gnu.org> |
| |
| Reinstate the memory handling improvements from the patch I just |
| reverted. Relevant ChangeLog entries repeated here: |
| |
| * m4/module.c (m4_module_remove): New function that holds the core |
| of the old m4_module_unload. |
| (m4_module_unload): Use it. |
| (m4_module_unload_all): When we know the modules will never be |
| used again (i.e. on exit), free up as much module memory as |
| possible. There are still some artifacts from resident modules |
| living inside ltdl.c, but everything else is freed. |
| * m4/debug.c (m4_debug_exit): Free memory allocated in |
| m4_debug_init(). |
| * m4/input.c (m4_input_exit): Ditto wrt m4_input_init(). |
| * m4/output.c (m4_output_exit): Ditto wrt m4_output_init (). |
| * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap (). |
| * m4/m4module.h: Updated prototypes. |
| * m4/hash.c (m4_hash_exit): Free the nodes on the free list. |
| * m4/hash.h: Updated prototypes. |
| * src/main.c (main): Use all these new functions to clean up as |
| much memory as possible before exit. |
| |
| 2001-09-30 Gary V. Vaughan <gary@gnu.org> |
| |
| Reverted my large patch for removing the old m4_symbol |
| structure on 2001-09-20. We are still not happy about the way |
| trace works in conjunction with defn and undefine, and leaving |
| the reverted patch active prevents us from moving the traced |
| bit from the definition back to the symbol. |
| |
| 2001-09-30 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.in: Moved to... |
| * configure.ac: ...here. Added a libtool like timestamped |
| banner, and tidied up the libltdl cruft. |
| * config/mkstamp: Script to extract a timestamp from ChangeLog. |
| * modules/Makefile.am (INCLTDL): Removed. This is required |
| only when libltdl is configured in a subdirectory. |
| * src/Makefile.am: Ditto. |
| (LIBADD_DL): No need to add this again, libtool already knows |
| that libm4.la depends on it. |
| * m4/Makefile.am: Automake sets variables from AC_SUBST. Use |
| them. |
| |
| * TODO: stackovf.c is basically broken. |
| Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr> |
| |
| 2001-09-28 Akim Demaille <akim@epita.fr> |
| |
| * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped. |
| |
| 2001-09-27 Akim Demaille <akim@epita.fr> |
| |
| * tests/m4.in: Don't use short options. |
| Simplify the stderr signature normalization. |
| |
| 2001-09-27 Akim Demaille <akim@epita.fr> |
| |
| tests/m4 shall be position independent. |
| |
| * tests/m4.in: New. |
| * tests/m4: Remove. |
| * tests/testsuite.at: No args to AT_INIT. |
| * configure.in, tests/Makefile.am: Adjust. |
| |
| 2001-09-22 Akim Demaille <akim@epita.fr> |
| |
| Autotest has changed again. |
| |
| * tests/Makefile.am (DISTCLEANFILES): Add package.m4. |
| (package.m4): Remove. |
| * configure.in: Adjust to LIBADD_GMP. |
| |
| 2001-09-21 Gary V. Vaughan <gary@gnu.org> |
| |
| * config/gmp.m4 (AC_ARG_WITH): Removed. |
| (GMP_LIB): Renamed to LIBADD_GMP for consistency. |
| (AC_LIB_GMP): When performing a test compile against libgmp, |
| include the header gmp.h if possible, and link against -lgmp. If |
| they both work define USE_GMP. |
| * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP. |
| (mpeval_LTX_init_func): Complain on load that there was no libgmp |
| at compile time. |
| |
| 2001-09-20 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/evalparse.c: Moved to... |
| * modules/evalparse.c: ...here. This code is shared between |
| modules/mpeval.c and modules/m4.c, so there is no need to pollute |
| the libm4 API with its details. Moderately rewritten to interface |
| into its clients more simply. |
| * m4/eval.c: Deleted. Migrated functionality to... |
| * modules/m4.c: ...here. |
| (builtin_eval): Implemented in terms of the new interface style. |
| * modules/mpeval.c (builtin_mpeval): Ditto. |
| * m4/m4module.h: Removed references to the former m4/eval.c. |
| * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c. |
| (EXTRA_libm4_la_SOURCES): Deleted. |
| * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c. |
| (EXTRA_mpeval_la_SOURCES): Reference evalparse.c. |
| |
| 2001-09-20 Akim Demaille <akim@epita.fr> |
| |
| * config/gmp.m4 (AM_WITH_GMP): Rename as... |
| (AC_LIB_GMP): this. |
| By default, use gmp. |
| Massive revamping. |
| * configure.in: Adjust. |
| Use Automake conditionals for USE_GMP. |
| Always compute sizeof (long long int). |
| This was a bug BTW, as `eval' (not `mpeval') depends on it: |
| before, it was used _only_ if mpeval was not activated. |
| * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES) |
| (mpeval_la_LIBADD): New macros. |
| * modules/mpeval.c: No longer be conditioned by WITH_GMP. |
| Indent. |
| * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4. |
| * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not |
| WITH_GMP. |
| |
| 2001-09-20 Akim Demaille <akim@epita.fr> |
| |
| * tests/Makefile.am (package.m4): New. |
| * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS. |

| More cleanup. After the last patch, m4_symbol holds nothing but |
| the head of a chain of m4_token_data. So I have removed the old |
| m4_symbol, so that m4_token_data chains are stored directly in the |
| value cell of a hash table node. But there's more... m4_symbol |
| was a more natural name for the symbol value cell, and now that it |
| is gone I have renamed the former m4_token_data structure to |
| m4_symbol. This change turned out to be a pig to get right, since |
| the original code didn't need to modify the value cell itself, |
| since changing the chain happened inside the m4_symbol that used |
| to be returned -- I had to pass the address of the value cell |
| across various function calls, incase the head value changed. I |
| also tightened up the memory management to help me find a nasty |
| memory corruption bug that took me all night to track down... |
| |
| * m4/m4private.h (struct m4_symbol): Removed. |
| (struct m4_token_data): Renamed to `struct m4_symbol'. Updated |
| all references. |
| * m4/hash.c (m4_hash_iterator_value): Return the address of the |
| value cell. Updated all callers. |
| * m4/symtab.c: Took advantage of the simplification in the data |
| structures to rewrite a lot of this file more simply. There is |
| still some room for optimisation here, but we should tackle that |
| systematically closer to the release. |
| |
| * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it |
| revealed. This version is ahead of CVS libtool until I get chance |
| to flush my changes. |
| * m4/module.c (m4_module_remove): New function that holds the core |
| of the old m4_module_unload. |
| (m4_module_unload): Use it. |
| (m4_module_unload_all): When we know the modules will never be |
| used again (i.e. on exit), free up as much module memory as |
| possible. There are still some artifacts from resident modules |
| living inside ltdl.c, but everything else is freed. |
| * m4/debug.c (m4_debug_exit): Free memory allocated in |
| m4_debug_init(). |
| * m4/input.c (m4_input_exit): Ditto wrt m4_input_init(). |
| * m4/output.c (m4_output_exit): Ditto wrt m4_output_init (). |
| * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap (). |
| * m4/m4module.h: Updated prototypes. |
| * m4/hash.c (m4_hash_exit): Free the nodes on the free list. |
| * m4/hash.h: Updated prototypes. |
| * src/main.c (main): Use all these new functions to clean up as |
| much memory as possible before exit. |
| |

| |
| The `traced' flag needs to be attached to the definition of a |
| symbol rather than the current symbol containing the definition. |
| Implementing this showed up some long standing post 1.4 bugs in |
| flag propogation which I also fixed. |
| |
| * m4/m4private.h (struct m4_symbol): Remove the traced flag. |
| (struct m4_token_data): And add it back in here. |
| * m4/input.c (init_macro_token): Propogate the traced flag |
| correctly. |
| * m4/macro.c (expand_argument): Ditto. |
| * tests/builtins.at (trace2, trace3): New tests based on Akim's |
| sadistic email ;-) |
| |
| 2001-09-08 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/m4private.h (struct m4_token_data): Simplified by removing |
| the redundant `traced' flag, and one level of structure nesting. |
| (M4_TOKEN_DATA_FUNC_TRACED): Removed. |
| * m4/input.c (init_macro_token): No need to initialise removed |
| `traced' field. |
| * m4/macro.c (expand_argument): No need to copy it either. |
| * m4/utility.c (m4_token_data_func_traced): Or provide an access |
| function. |
| |
| * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer |
| dependant on multiple symbols with the same key, so preserving |
| relative symbol order in each bucket during resizing is no longer |
| required. The resize function is considerably faster as a result. |
| |
| * m4/m4module.h, m4/builtin.c, m4/symtab.c: |
| s/m4_symbol_insert/m4_symbol_define/g; |
| s/m4_builtin_insert/m4_builtin_define/g; |
| s/m4_macro_insert/m4_macro_define/g. Updated all callers. |
| |
| 2001-09-08 Gary V. Vaughan <gary@gnu.org> |
| |
| Get rid of m4_symbol_lookup_t entirely. With Akim's earlier |
| commits, the m4_lookup_symbol dispatch function is split into |
| specialised functions that must be called directly. |
| |
| * m4/m4module.h (m4_symbol_lookup_t): Removed. |
| * m4/symtab.c (m4_lookup_symbol): Removed. |
| (m4_symbol_builtin, m4_symbol_macro): New functions. |
| * m4/builtin.c (m4_builtin_define): Split into... |
| (m4_builtin_pushdef, m4_builtin_insert): ...these. |
| (m4_macro_define): Split into... |
| (m4_macro_pushdef, m4_macro_insert): ...these. |
| * src/main.c (main): Set command line macros from `-D' parameters |
| using `m4_macro_define'. |
| |
| 2001-09-08 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/symtab.c (m4_symtab_remove_module_references): Renamed as |
| this from m4_remove_table_reference_symbols(). |
| * m4/m4module.h, m4/module.c: Updated all references. |
| |
| 2001-09-07 Akim Demaille <akim@epita.fr> |

| * configure.in: We now need Autoconf 2.52e. |
| * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF' |
| and `M4_SYMBOL_DELETE'. |
| * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust. |
| * src/main.c (main): Adjust. |
| |
| 2001-09-06 Gary V. Vaughan <gary@gnu.org> |
| |
| Fix the obstack.h problem once and for all! At configure time we |
| can test for a system supplied obstack.h: depending on the |
| result, we now generate system.h with an #include of the correct |
| header. As a bonus, I've also added a --with-included-obstack, |
| incase the user doesn't like the system obstack for some |
| reason... and also we can test the shipped obstack on a system |
| that has oe of its own. We also now need to be careful to add |
| build directories to the include search path, since the generated |
| system.h will be in the build tree. |
| |
| * configure.in (AC_CONFIG_FILES): Generate system.h from |
| system-h.in. |
| * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to |
| include the system obstack header or the copy shipped with M4. |
| Allow the user to override configure and force the build to use |
| the shipped version. |
| * m4/system-h.in: New file, template for... |
| * m4/system.h: ...this. Now deleted. |
| * m4/m4module.h: Include system.h before everything else. |
| * src/freeze.c: Ditto. |
| * m4/Makefile.am (dist-hook): Remove generated system.h. |
| (INCLUDES): Check builddir for generated headers before checking |
| srcdir. |
| * modules/Makefile.am (INCLUDES): Ditto. |
| * src/Makefile.am (INCLUDES): Ditto. |
| |

| program name, and assertions. |
| |
| * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used. |
| (M4WARN): New. |
| * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef) |
| (m4_symbol_delete): |
| Use assert for internal errors. |

| |
| * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP. |

| |
| 2001-09-03 Gary V. Vaughan <gary@gnu.org> |
| |
| Bootstrap will now work with Libtool 1.4.1 or higher: |
| * bootstrap: Remove stale autom4te.cache files when |
| rebootstrapping. |
| * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and |
| libtool.m4. |
| * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and |
| libtool.m4 directly. |
| Run libtoolize to refresh ltmain.sh. |
| * config/ltmain.sh: Deleted. |
| * acinclude.m4: Deleted. |
| * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1. |
| |
| * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback |
| implementation for the cvs impaired libtool user. |
| |
| 2001-09-03 Akim Demaille <akim@epita.fr> |
| |
| * m4/symtab.c (m4_lookup_symbol): Give more details when reporting |
| internal errors. |
| Avoid using `default' in switch, as it hides useful compiler |
| warnings when a case is forgotten. |
| |
| 2001-09-03 Akim Demaille <akim@epita.fr> |
| |
| * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there |
| is no such thing as `WITH_MODULES'. |
| |
| 2001-09-03 Akim Demaille <akim@epita.fr> |
| |
| Improve the test suite's selfcontainedness. |
| |
| * doc/m4.texinfo: Let `input.m4' be the input file, not `in'. |
| (Include, Undivert): Tag the other input files. |
| * tests/generate.awk: Catch `@comment file:'. |
| `-I $src' is no longer needed. |
| `next' is really like `return': the rest is skipped. |
| Adjust to `input.m4'. |
| (fatal): New function. |
| * tests/foo, tests/incl.m4: Remove. |
| |
| 2001-09-01 Gary V. Vaughan <gary@gnu.org> |
| |
| The shadowing mechanism and, infact, the whole symbol table |
| implementation was creaking under the weight of the features piled |
| on top of it. We now have a separate hash table module which will |
| dynamically resize to keep symbol density withing good performace |
| limits, and a new symtab module layered above it. Symbol lookups |
| are now marginally more efficient (since the shadowed flag is no |
| longer required) and symbol removal, such as on module unload, is |
| considerably faster due to a reorganisation of the data structures |
| used in symtab.c. |
| |
| * src/main.c (main): Don't mention `-H'. |
| * doc/m4.texinfo (Invoking m4): Document that -H no longer has any |
| effect. |
| * NEWS: Updated. |
| * m4/hash.c: New generalised dynamic hash table data structure |
| management module. |
| * m4/hash.h: Public interface. |
| * m4/Makefile.am (pkginc_HEADERS): Add hash.h. |
| (libm4_la_SOURCES): Add hash.c. |
| * m4/symtab.c: More or less rewritten from scratch, within the |
| bounds of the previous API. |
| (m4_symtab_apply): A cleaner version of the old hack_all_symbols |
| call. Updated all callers. |
| * m4/m4module.c: #include <m4/hash.h>, and changed all affected |
| declarations to reflect API changes. |
| (M4INIT): Generate a declaration too, to avoid the warning with |
| --enable-debug builds. |
| (M4FINISH): Ditto. |
| (HASHMAX): Removed. |
| * m4/utility.c (hash_table_size): Removed. |
| (m4_dump_symbols): Rewritten to build and qsort an array of symbol |
| names, which are then looked up by builtin_dumpdef() as necessary. |
| This implies a small speedup in builtin_symbols(), which discarded |
| all of the symbol info under the old call. |
| * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol |
| shadowing is implicit in respect to the new data structures. |
| symbol names are no longer duplicated here, they are stored in the |
| key field of the hash table. |
| Moved macro_args and blind_no_args... |
| (m4_token_data): ...to here. |
| m4/macro.c (expand_macro): Added a name argument since the symbol |
| name is no longer copied into each struct m4_symbol. Modified all |
| callers. |
| (collect_arguments): Ditto. |
| * modules/m4.c (set_trace): Ditto. |
| * modules/gnu.c (builtin_symbols): Updated. |
| * src/freeze.c (produce_symbol_dump): Much improved in light of |
| the improved symbol table layout. |
| |
| 2001-09-01 Gary V. Vaughan <gary@gnu.org> |
| |
| * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed |
| to M4_SYMBOL_NEXT. |
| (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'. |
| (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS, |
| SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC, |
| SYMBOL_HANDLE): Ditto. |
| * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c, |
| modules/gnu.c, modules/m4.c, src/freeze.c, |
| src/main.c: Updated all references. |
| |
| * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since |
| Automake 1.5 chokes on dynamic source file lists, Besides, it is |
| already listed in m4_LDADD... how did that ever used to work? |
| * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual |
| link. |
| * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto. |
| Suggested by Tim Van Holder <tim.van.holder@pandora.be> |
| |
| * tests/m4: Don't call the m4 wrapper script with libtool, it |
| works fine all by itself. |
| |
| 2001-08-30 Gary V. Vaughan <gary@gnu.org> |
| |

| removed. |
| * po/POTFILES.in: modules/changeword.c removed. |
| * tests/atlocal.in (ENABLE_CHANGEWORD): Removed. |
| * tests/builtins.at (changeword): Test removed. |
| |
| 2001-08-30 Akim Demaille <akim@epita.fr> |
| |
| * bootstrap.sh: Create aclocal.m4 instead of modifying it. |
| This also help having a single list of m4 files: in |

| (ACLOCAL_MACROS): this. |
| (list-standard-macros): Remove. |
| (spy): New. |
| |
| 2001-08-29 Gary V. Vaughan <gary@gnu.org> |
| |
| In an attempt to moderate my egomania... |
| * tests/modules.at: Remove attributions. |
| |
| * tests/generate.awk: When making substitutions to "@&t@", either |
| "&" or "\&" in the substitution string argument to gsub refer back |
| to the matched text. "@\\&t@" seems to work though, Tests 43 and |
| 67 now pass for me. |
| |

| |
| 2001-08-27 Akim Demaille <akim@epita.fr> |
| |
| * tests/Makefile.am (installcheck-local): Don't use |
| `dc_install_base' which is not visible here, but `exec_prefix' |
| which is clearly the RT anyway. |
| * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is |

| invocation of --discard-comments. |
| |
| 2001-08-27 Akim Demaille <akim@epita.fr> |
| |

| aclocal. |
| * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs |
| until it reads the traces by itself. |
| * configure.in: Require Autoconf 2.42c as we are now using |
| AC_CONFIG_TESTDIR instead of AT_CONFIG. |

| Ansify the source. Previously we had a mix, where my code was |
| in a K&R compatible style, and the preexisting code was in ANSI |
| style. Nothing is lost wrt release 1.4 by reverting to ANSI, |
| and now the code base is much cleaner. |
| |

| |
| * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be |

| |
| 2001-08-20 Akim Demaille <akim@epita.fr> |
| |
| * config/atconfig.m4: New, until part of Autoconf per se. |

| |
| * m4/utility.c (m4_numeric_arg): Spell out the culprit. |
| * modules/m4.c (undivert): Disable the possibility of undiverting |
| several files at once: it is not documented, it is inconsistent |
| with the other macros, it can be straightforwardly mocked by |
| several invocations, and most importantly, it prevents the |
| possibility of other kinds of extension. |
| Use `m4_numeric_arg'. |
| |
| 2001-08-20 Akim Demaille <akim@epita.fr> |
| |
| * examples/include.m4: Typo. |
| * tests/generate.awk: Really add it. |

| |
| 2001-08-20 Akim Demaille <akim@epita.fr> |
| |
| Use sprintf, not ecft and friends since it is standard, portable, |
| simplifies the code, and since the latter is even deprecated |
| according to the GNU libc documentation. |

| |
| 2001-08-19 Gary V. Vaughan <gary@gnu.org> |

| |
| Drop Autoconf 2.13 compatibility. |
| |

| it's defined, M4sugar moved it as m4_changeword. |
| And anyway, proper quotation is enough. |
| (m4_pattern_allow): As it exists in 2.50, just use it. |
| (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS. |
| Don't handle Gettext's duties, let it handle them. |
| * config/gnu-obstack.m4: Use m4_pattern_allow directly. |
| |
| 2001-08-17 Akim Demaille <akim@epita.fr> |
| |
| * modules/m4.c (m4_dumpdef): Output to stderr, not m4_debug. |
| (m4_errprint): Use fputs. |
| * doc/m4.texinfo (Invoking m4) <--error-output>: errprint and |

| violations, renamed to... |
| (m4_module_init_func, m4_module_finish_func): ...these, |
| respectively. |
| (M4INIT_HANDLER): Clean way to declare init functions in modules. |
| (M4FINISH_HANDLER): And similarly for finish functions. |
| * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER |
| -- Add indirection to the CONC macro so that arguments are |
| correctly expanded. |
| * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER. |
| * modules/shadow.c (m4_init_module): Ditto. |

| (m4_module_data): ...structure without all the wrapper fields. |
| Instances of this new structure are stored associated lt_dlhandles |
| with lt_dlcaller_data_set(). |
| * m4/builtin.c (m4_builtin_define): Takes a handle argument |
| instead of the old module argument. |
| (m4_builtin_table_install): Ditto. |
| * modules/load.c (m4_resident_module): Removed. This is no |

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

| field. |
| (m4_push_macro): Add a `handle' argument. Changed all callers. |

| |
| 2001-08-14 Gary V. Vaughan <gary@gnu.org> |

| and shipped version based on configure tests. |
| * src/freeze.c (obstack.h): Ditto. |

| interactive mode off. |
| |
| 2001-08-10 Akim Demaille <akim@epita.fr> |
| |
| * configure.in: Require Autoconf 2.52. |
| (AC_ARG_PROGRAM): Remove, handled by Automake. |
| (m4_getopt): Rename as... |
| (m4_getopt_h): this. |
| Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'. |
| Undefine `changeword' only if defined. |
| * config/gnu-obstack.m4: Require Autoconf 2.52. |
| (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'. |

| Move the implementation of GMP support for the mpeval() builtin |
| into a loadable module that depends on libgmp. mpeval() and |
| eval() share a common parser, now in m4/evalparser.c; the code |
| in m4/numb.c and m4/numb.h is now physically split between |
| m4/eval.c (the eval() backend) and modules/mpeval.c (the |
| mpeval() backend), rather than being differentiated by cpp |
| macros and multiple inclusion. The mpeval module is always |
| built but will generate an diagnostic if it is used from an |
| installation that didn't link in the gmp library. |
| * modules/Makefile.am: build and install the new mpeval module. |
| * modules/mpeval.c: Now contains the former parts of m4/numb.c |
| and m4/numb.h that are required for gmp support in mpeval(). |
| * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c. |
| * m4/evalmp.c: Removed. |
| * m4/m4module.h: Removed conditional prototype for |
| m4_mp_evaluate(). |
| * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c |
| and m4/numb.h that do not rely on gmp. |
| * m4/evalparse.c: New file, contains the shared parts of the |
| eval() and evalmp() parser implementations, and is no longer |
| unencumbered by cpp magic to uncover the right parts. |
| * m4/numb.h: Removed. It's former contents are split between |
| m4/eval.c and modules/mpeval.c. |
| * m4/numb.c: ditto. |
| |
| * tests/other-tests/changeword.test: New test. Rudimentary |
| testing of changeword builtin runs only if --wnable-changeword |
| was used at configure time. |
| * tests/mkconfig.sh: Solaris sed (at least) does not parse nested |
| alternation correctly. Split into two expressions to compensate. |
| * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp. |
| * modules/Makefile.am: Build changeword module. |
| * modules/changeword.c (m4_macro_table): Define __m4_changeword__ |
| only when --enable-changeword was passed to configure. |
| (builtin_changeword): If --enable-changeword was not used, then |
| report that changeword() builtin has no support in m4 binary. |
| |

| |
| * src/main.c (main): Fixed a particularly nasty bug is |
| user_search_path setting -- the -M flag processing must be |
| extremely careful with search path ordering, or else the default |
| installed module directory (possibly containing modules from a |
| previous release) is placed earlier in the search path than any -M |
| arguments (which are relied upon to load uninstalled modules with |
| most of the tests in the regresion suite). |
| |
| * modules/load.c (builtin_load): Nasty hack to prevent adding |
| symbols to symtab again if a module is loaded more than once. |
| * modules/m4.c (builtin_ifelse): removed unused variable argv0. |
| |
| * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a |
| possible NULL pointer dereference. |
| |
| * m4/module.c (m4_module_find_by_modname): Renamed from |
| m4_module_modname_find. Fixed all references. |
| (m4_module_find_by_builtin): New function. |
| |
| * modules/modfreeze.test: load the `load' module with each |
| invocation. |
| * src/freeze.c (produce_frozen_state): Simplified in light of |
| module field in m4_symbol. Allow a third argument for text macros |
| to name the originating module. |
| (reload_frozen_state): ditto. |
| * m4/m4module.h: Fixup prototypes. |
| * m4/builtin.h (m4_builtin_define): Add a module argument so |
| that symbols can be registered against the defining module. |
| (m4_macro_define): ditto. |
| * m4/m4private.h (m4_symbol): Make the module field const to save |
| on casting in the rest of the code. |
| (SYMBOL_MODULE): New macro. |
| |
| * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid |
| symbol reference maintenance bugs when removing a symbol from the |
| symtab. |
| |
| * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks. |
| |
| 2000-11-27 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.in (m4_cv_func_obstack): A better check for whether |
| libc has an obstack implementation. |
| * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h. |
| |
| * configure.in (--with-modules): Changed semantics. This |
| option is now used to list modules to be preopened. |
| * src/m4.h: #include "ltdl.h" unconditionally. |
| * src/main.c: Removed all dependencies on WITH_MODULES. |
| * src/freeze.c: ditto. |
| * modules/Makefile.am: ditto. |
| * m4/m4.c (builtin_m4exit): ditto. |
| * modules/modpath1.test: ditto. |

| * modules/unload.test: ditto. |
| |
| * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it |
| comes up on demand in LTLIBOBJS now. |
| * configure.in (getopt_long): Creating and relying on a link for |
| getopt.h on hosts with no getopt_long() of thier own works |
| correctly now. This is necessary so that callers of getopt_long() |
| can simply `#include <getopt.h>': the naive way of doing this |
| would end up using our own getopt.h and the installed |
| getopt_long(), which is asking for trouble! |
| (obstack_init): A similar argument applies to obstack.h and |
| obstack_init(). |
| |
| * m4/ltdl.c: Upgraded to latest bleeding edge version again. |
| On Solaris-2.5 (at least) the native dlopen implementation |
| gets confused about m4.o when looking for module "m4". This |
| version always looks for .la an .$lib_ext suffixed names first |
| to work around the problem. Sigh. |
| |
| * po/POTFILES.in: Take account of these file movements. |
| * src/Makefile.am (m4_SOURCES): removed eval.c. |
| (EXTRA_m4_SOURCES): removed numb.c and numb.h. |
| * m4/Makefile.am (libm4_la_SOURCES): added eval.c. |
| (EXTRA_libm4_la_SOURCES): added numb.c and numb.h. |
| * modules/m4.c (builtin_eval): Use m4_evaluate(). |
| * m4/eval.c: Moved here from src/eval.c to facilitate |
| implementation of eval() builtin as part of the `m4' loadable |
| module. |
| (m4_evaluate): renamed from evaluate for namespace cleanliness. |
| * m4/numb.c: Moved here from src/numb.c, since it is #included |
| into eval.c at compile time. |
| * m4/m4module.h (m4_evaluate): Added prototype. |
| * src/m4.h (evaluate): Removed prototype. |
| |
| 2000-11-25 Gary V. Vaughan <gary@gnu.org> |
| |
| * modules/perl.c (builtin_perleval): Use PL_na for |
| compatibility with perl-5.6. |
| |
| * src/main.c (main): It is now safe to |
| ``m4_module_install("m4")'', without tripping over the m4 |
| binary itself! |
| * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge |
| versions having fixed the insidious module search order bug. |
| |
| * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are |
| supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead. |
| |
| * configure.in: Figure out whether to use the installed |
| getopt.h or the supplied one. |
| * src/Makefile.am: ditto. |
| |
| * po/POTFILES.in: List files in their new positions. |
| |
| * config/ltmain.sh: This needs to be checked in to match the |
| libtool macros copied to acinclude.m4 (until a released |
| libtool copes with m4's needs). |
| * bootstrap: Run gettextize. |

| and then in $(top_srcdir)/lib (for eg. "m4private.h"). |
| * src/Makefile.am (m4_LDADD): replace libi/libm4.la with |
| m4/libm4.la. |
| * m4/m4error.h: Renamed error.h, for installation to |
| $prefix/include/m4.. |
| * m4/m4obstack.h: Renamed obstack.h, for same reason. |
| * m4/m4regex.h: Renamed regex.h, for same reason. |
| * m4/m4error.c: Renamed error.c, and use #include "error.h". |
| * m4/m4obstack.c: Renamed obstack.c, and fix #includes. |
| * m4/m4regex.c: Renamed regex.c, and fix #includes. |
| |
| * lib: moved to m4 to easily support header installation to |
| $prefix/include/m4. |
| * Makefile.am (SUBDIRS): renamed lib dir to m4. |
| * configure.in (AC_OUTPUT): reference m4/Makefile.in. |
| * acm4/regex.m4: Point to m4/regex.c. |
| |
| * examples/foreach.m4: Sanitise quoting. |

| |
| 2000-01-17 Gary V. Vaughan <gary@gnu.org> |
| |
| * src/ltdl.c: Use access() to abort doomed module load attempts |
| if module file does not exist. |
| |
| * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and |
| getopt1.o will already be used if appropriate, so I moved getopt.c |
| and getopt1.c from m4_SOURCES to EXTRA_SOURCES. |
| |
| * modules/modpath1.test: Use correct filename in header line. |
| * modules/modpath2.test: ditto. |
| * modules/modpath3.test: ditto. |
| * modules/modpath4.test: ditto. |
| |
| Without these changes lt_dlopen("test") attempts to |
| LoadLibrary("/bin/test") on Windows, which although harmless |
| generates a spurious error message which spoils most of the tests: |
| * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 / |
| (TESTS): s/test.test /modtest.test / |
| (pkglibexec_LTLIBRARIES): s/test.la /modtest.la / |
| (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest. |
| * modules/modpath1.test: s/test.m4 /modtest.m4 / |

| * modules/modpath4.test: ditto. |
| * modules/modpath3.test: s/-m test /-m modtest / |
| * modules/shadow.m4: use {un,}loadmodule(`modtest'). |
| |
| 2000-01-16 Gary V. Vaughan <gary@gnu.org> |
| |
| * src/ltdl.c (find_file): Updated to new version with fixed memory |
| allocation bug in `next'. |
| * src/ltdl.h: updated to match. |
| |
| * modules/Makefile.am: Cleaned up and reordered. |
| |
| 2000-01-16 René Seindal <rene@seindal.dk> |
| |
| * modules/Makefile.am (TESTS): New tests for the module system. |
| |
| * modules/*.test: New files. |
| |
| * src/m4.c (main): Added call to module_init(). |
| Treats -M and -m as the arguments -D -U and -t, ie deferred. |
| |
| * src/m4.h: Added declaration of module_init(). |
| |
| * src/module.c (module_init): No longer static |
| |
| * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS): |
| Added to shut up automake about non standard libtool library |
| names. |
| |
| * src/module.c: Disabled DEBUG by default. |
| |
| * modules/README: Changed example from unload.m4 to shadow.m4 |
| |
| * modules/shadow.m4: Renamed from unload.m4 |
| |
| * modules/Makefile.am (EXTRA_DIST): Removed unload.m4. |
| |
| * src/m4.c (main): Functionality for -m and -M were reversed. |
| Fixed. |
| |
| 2000-01-12 Gary V. Vaughan <gary@gnu.org> |
| |
| * doc/help2man.pl: updated to version 1.020. |
| |
| * lib/COPYING.LIB: updated to version 2.1. |
| |
| * lib/m4module.h: restructure the M4_SCOPE code to work when |
| creating a dll which links with libm4.la and both DLL_EXPORT |
| (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are |
| both defined. |
| |
| 2000-01-11 Gary V. Vaughan <gary@gnu.org> |
| |
| Merged the following changes from my tree: |
| |
| 1999-06-15 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been |
| ported to compile shared libs. |
| |
| * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to |
| use `__declspec(dllimport)' when linking libm4.la on win32. |
| * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary. |
| |
| * configure.in (M4OBJS): Discover whether we need the shipped |
| implementation of getopt_long. |
| * src/Makefile.am (m4_LDADD): Link the getopt objects into the |
| main binary here, as opposed to the module library in lib/libm4.la. |
| |
| 1999-06-14 Gary V. Vaughan <gary@gnu.org> |
| |
| * modules/README: Updated to describe the improved libltdl based |
| module scheme. |
| * README (cygwin): Added some compilation notes for building m4 |
| correctly under cygwin. |
| * TODO: Cleaned out the entries for the module system since they |
| are now implemented. |
| |
| * *.[ch]: __P is in the compiler's reserved namespace, so replaced |
| all instances of __P with M4_PARAMS. |
| |
| * lib/getdate.h: removed unreferenced file. |
| |
| * lib/m4private.h: New file to define the private interface to the |
| token_data struct, which must be shared between m4module.c, and |
| builtin.c but not exported to modules built from the installed |
| m4module.h since it's size changes depending on compile time |
| options. |
| |
| * src/m4.h: Lots of stuff moved to lib/m4module.h. |
| |
| * lib/m4module.h: New file to define the interface available when |
| compiling m4 modules. |
| * lib/m4module.c: Moved parts of builtin.c, and m4.c which are |
| necessary for module compilation into this new file. |
| |
| * lib/Makefile.am (include_HEADERS): install headers (renamed to |
| avoid nameclash with other system headers) necessary for compiling |
| modules. |
| (libm4_la_SOURCES): always include error.c, obstack.c and regex.c |
| so that modules can include the (renamed) installed headers and |
| be guaranteed a matching implementation. |
| * lib/m4error.h: renamed from error.h. |
| * lib/m4obstack.h: renamed from obstack.h. |
| * lib/m4regex.h: renamed from regex.h. |
| * configure.in (AC_REPLACE_FUNCS): Don't look for a system |
| implementation, simply include the shipped version |
| unconditionally, otherwise it is hard for a module to know |
| whether the m4obstack.h header it is using matches the |
| implementation it ends up linking against. |
| (jm_WITH_REGEX): Include regex into libm4 unconditionally for |
| the same reason. |
| |
| 1999-05-18 Gary V. Vaughan <gary@gnu.org> |
| |
| * examples/misc.test: Don't run this test on machines which don't |
| have a root user in /etc/passwd (e.g. cygwin). |
| |
| * tests/get-them (/^@example$/): Error messages might have a |
| ``.exe'' suffix to the program name, or else use the libtool |
| ``.libs/lt-m4'' binary, or generally have an unexpected path. All |
| of these cases are now catered for when comparing error messages |
| in generated tests. |
| * tests/other-tests/*.test: ditto. |
| * examples/*.test: ditto. |
| |
| * tests/defs (M4): use libtool execute mode. |
| * examples/defs (M4): ditto. |
| |
| * tests/get-them (END): explicitly close any open file. |
| (printthem): In a regular expression, '{' is the start of a repeat |
| count! Use `[{]' for a literal open brace. |
| (/^@node /): Don't use substr on a string shorter than the trim |
| length. |
| |
| 1999-05-17 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.in (LTLIBOBJS): calculated from LIBOBJS, and |
| substituted. |
| (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen. |
| |
| 2000-01-10 Andreas Schwab <schwab@suse.de> |
| |
| * tests/other-tests/gmp.test: Find config.sh in build directory. |
| |
| * configure.in: Find tests/mkconfig.sh in $srcdir. |
| |
| * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in |
| <signal.h> (for SUS2 compliant systems). |
| |
| * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to |
| HAVE_SIGINFO_H. |
| |
| 2000-01-10 René Seindal <rene@seindal.dk> |
| |
| * Prerelease 1.4o. |
| |
| * TODO, NEWS: Cleaned up and updated. |
| |
| * src/m4.c (main): New variable exit_status for exit status in |
| case of unreadable files. Now m4 will exit with EXIT_FAILURE if a |
| file cannot be read instead of EXIT_SUCCESS. |
| |
| * src/builtin.c (m4_indir): Changed error message to help |
| translators (from Akim Demaille <demaille@inf.enst.fr>). |
| |
| * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from |
| Cygnus. |
| |
| * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version |
| from glic 2.1.2. |
| |
| * src/input.c (match_input): Reordering of code, to avoid multiple |
| calls to push_string_init() from obstack_grow(), which can happen |
| with some compilers (found and fixed by James Bonfield |
| <jkb@mrc-lmb.cam.ac.uk>). |
| |
| * src/stackovf.c: Added prototypes for ultrix. |
| (setup_stackovf_trap): Added __P to cast. |
| (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>) |
| |
| 2000-01-09 René Seindal <rene@seindal.dk> |
| |
| * doc/m4.texinfo (Changequote): Added comment about changing |
| quotes when the old quote is a part of the new. |
| |
| * src/builtin.c (expand_ranges): Added break after trailing dash. |
| This caused misbehavious on some systems (found and fixed by Akim |
| Demaille <demaille@inf.enst.fr>). |
| |
| * AUTHORS: Thomas Tanner included |
| |
| * acconfig.h: Added entry for ss_sp (see below). |
| |
| * configure.in (use_stackovf): Added check for stack_t with member |
| ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert |
| <eggert@twinsun.com>). |
| |
| * doc/m4.texinfo (Frozen files): Added a simpler example for |
| generating frozen files from several input files. |
| |
| 1999-11-14 Paul Eggert <eggert@twinsun.com> |
| |
| * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c, |
| lib/regex.c, lib/xmalloc.c. |
| |
| 1999-11-10 René Seindal <rene@seindal.dk> |
| |
| * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal. |
| |
| * src/module.c: reindented. |
| (module_load): return if this is a repeated load of same module. |
| (module_init): slight change of logic to avoid repeated |
| initialisation debug messages. |
| |
| * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included |
| in the distribution. |
| |
| * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence |
| automake warnings about missing lib prefix. |
| (time_la_LDFLAGS): ditto |
| (stdlib_la_LDFLAGS): ditto |
| |
| 1999-11-10 Paul Eggert <eggert@twinsun.com> |
| |
| * src/m4.h: Include error.h, since our macros use error. |
| * src/m4.c: Don't need to include error.h. |
| |
| 1999-11-09 Paul Eggert <eggert@twinsun.com> |
| |
| * src/m4.h (voidstar): Define to void * if __STDC__ is defined |
| and zero, as Solaris 7 cc does. |
| (bcopy): Remove macro; no longer needed with new obstack.h. |
| |
| * src/output.c (freeze_diversions): Don't assume that a |
| diversion size can fit in `int'. Check for diversion file |
| size too large to be printed with `unsigned long'. |
| |
| * src/Makefile.am (CFLAGS): Omit -Wall. |
| |
| * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned. |

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

| * doc/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| * examples/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| * lib/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| (AUTOMAKE_OPTIONS): reduced strictness to allow COPYING.LIB. |
| * modules/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| * src/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| * tests/Makefile.am (MAINTAINERCLEANFILES): ditto. |
| |
| * acinclude.m4: removed. `aclocal -I acm4' handles this much |
| better. |
| * acm4/Makefile.am (ACINCLUDE_M4): ditto. |
| * acm4/gettext.m4: removed. It causes a multiple definition vs. |
| the installed gettext.m4 file when running aclocal. |
| |
| 1999-03-25 Gary V. Vaughan <gary@gnu.org> |
| |
| * configure.in (AM_INIT_AUTOMAKE): bumped version number to |
| distinguish this from the last prerelease. |
| (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library |
| in its own subdirectory. |
| |

| versionless module libraries. |
| * src/builtin.c (m4_load_module): use libltdl. |
| (module_unload_all): use libltdl. |
| * src/m4.c (module_init): initialise module loading on demand for |
| better diagnostics, and so that m4 will still work even if |
| the module code is broken. |
| * src/m4.h (module_init): removed. No longer relevant. |
| * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on |
| exported symbols for compatibility with dlpreopening. |
| * modules/test.c (m4_macro_table, m4_init_module, |
| m4_finish_module): ditto. |
| * modules/time.c (m4_macro_table): ditto. |
| |
| * bootstrap: New file. Runs all the autoutils in the right order |
| after a fresh checkout, or a make maintainer-clean. |
| |
| 1999-02-18 Akim Demaille <demaille@inf.enst.fr> |
| |
| * src/builtin.c (dump_symbols): New function, factoring common |
| content of m4_dumpdef and m4_symbols. |
| (m4_dumpdef): Use it. |
| (m4_symbols): New function, implementing `symbols'. Use it. |
| * doc/m4.texinfo: Fixed missing commas after @xref, so that the |
| file compile with modern makeinfo. |
| (Symbols): New node, documenting symbols. |

| __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for |
| configure time options. |
| |
| 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> |
| |
| * src/module.c (module_try_load): Don't try to be clever and |
| overwrite argument string. Instead allocate all constructed |
| strings locally, since they can have arbitrary lengths. Make |
| arguments pointers to const. |
| (module_search): Simplify due to above change. |
| |
| 1998-11-29 René Seindal <rene@seindal.dk> |
| |
| * Prerelease 1.4n. |
| |
| * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests. |
| |

| |
| * src/m4.c (main): New option -c --discard-comments. |
| New global variable discard_comments. |
| |
| * src/m4.h (token_type): New TOKEN_NONE for tokens to be |
| discarded, ie never returned from next_token(). |
| Added declaration of discard_comments. |
| |
| * src/input.c (next_token): Now loops until token type is not |
| TOKEN_NONE. Comments are now given this type when comments should |
| be discarded. |
| |
| * doc/m4.texinfo (Invoking m4): Updated for --import-environment |
| and mpeval. |
| |
| 1998-11-28 René Seindal <rene@seindal.dk> |
| |
| * src/m4.c (main): New option --import-environment (no single |
| letter option). |
| |
| * When configured with --with-gmp both the normal (fast) eval() |
| and the gmp aware mpeval() are defined. To restore previous |
| bahaviour use "define(`eval', defn(`mpeval'))". |
| |
| * tests/other-tests/gmp.m4: Changed to use mpeval(). |
| |
| * src/evalmp.c: New file for compiling eval.c as gmp aware. |
| Just defines USE_GMP if WITH_GMP is defined and includes eval.c. |
| |
| * src/eval.c: Now includes "numb.c" directly. Everything in this |
| file must by static, except evaluate(), which is changed to |
| mp_evaluate() if USE_GMP in force. |
| |
| * src/numb.c: Changed to be included by eval.c instead of being |
| compiled separately. Everything is declared static. |
| |
| * src/numb.h: Removed declarations of functions, as numb.c is now |
| included by eval.c. |
| |
| * src/builtin.c: Declaration of m4_mpeval() added. |
| Inserted `mpeval' in builtin table. |
| (do_eval): New function with common code for m4_eval and m4_mpeval. |
| (m4_mpeval): New function for gmp version of eval. |
| |
| * src/m4.h: Declaration of mp_evaluate(). |
| |
| * src/Makefile.am (m4_SOUCES): Includes mpeval.c. |
| (EXTRA_m4_SOURCES): Now has numb.c and numb.h |
| |
| * src/m4.c (main): m4 --version also shows which options were used |
| for compilation, such as: "GNU m4 1.4n (options: modules gmp)" |
| |
| 1998-11-27 René Seindal <rene@seindal.dk> |
| |
| * Error messages now always print program name before input file |
| name as specified by GNU coding standards. Reported by Akim |
| Demaille <demaille@inf.enst.fr>. |
| |
| * doc/m4.texinfo (Include): Change due to changed error message |
| format. |
| (Eval): Do. |
| |
| * tests/get-them: Minor change to sed script due to changed error |
| message format. |
| |
| * src/m4.c (print_program_name): New func used to print program |
| name, input file and line number in error (). Used as an |
| error_print_progname handler. |
| (reference_error): Removed. |
| (main): Assigns error_print_progname. |
| |
| * src/m4.h (M4ERROR): Removed reference_error (). |
| |
| 1998-11-25 René Seindal <rene@seindal.dk> |
| |
| * Updated to libtool 1.2b. |
| |
| * src/builtin.c (install_builtin_table): Added braces to avoid |
| warning of ambiguous 'else'. |
| |
| * src/module.c: Inserted search path code from path.c modified to |
| use new interface. |
| (module_init): Configured default path used only if M4MODPATH is |
| not set. |
| (module_try_load): Now reads libMODULE.la as generated by libtool |
| for actual module name. |
| (module_load): Gives better error messages on failure. |
| |
| * src/m4.h: Added declarations of structures and functions for |
| generic search path handling. |
| |
| * src/path.c: Removed all module specific code and introduced new |
| functions of more generic search path handling. |
| |
| 1998-11-24 René Seindal <rene@seindal.dk> |
| |
| * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using |
| included gettext, as <libintl.h> might not be found |
| otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>. |
| |
| 1998-11-22 René Seindal <rene@seindal.dk> |
| |
| * src/output.c (insert_diversion): Fixed bug that might cause m4 |
| to read from standard output! Triggered by input |
| 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0, |
| so now 'undivert(0)' does nothing. |
| |
| 1998-11-18 René Seindal <rene@seindal.dk> |
| |
| * Prerelease 1.4m. |
| |
| * src/input.c (set_word_regexp): Fixed a bug, where word_regexp |
| could be changed when compiling a illegal regexp, causing later |
| use of the regexp to dump core. |
| |
| * src/module.c (module_load): Changed error message to conform to |
| standards. |
| |
| * src/m4.c (usage): Added message about reporting bugs. |
| |
| * doc/m4.texinfo (Changeword): Corrected a wrong example. |
| (Changeword): Added note about the type of regexps used. |
| |
| * ltconfig, ltmain.sh: New files from Libtool 1.2. |
| |
| * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC |
| and AM_PROG_LIBTOOL. |
| |
| * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work |
| with libtool. |
| |
| * modules/Makefile.am: Changed completely to compile modules using |
| libtool. The modules are compiled as shared libraries, and are |
| renamed when installed. |
| |
| * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed |
| USE_SHL_LOAD to HAVE_SHL_LOAD |
| |
| * src/builtin.c (shipout_string): Now tests for a NULL string. |
| |
| * src/module.c: New level of indirection around non-portable |

| tests/ directory. |
| |
| * tests/Makefile.am (OTHER_TESTS): Added tests from the example/ |
| directory. The files stay there but the tests are run from the |
| tests/ directory. |
| |
| * tests/Makefile.am (EXTRA_DIST): Added run-test. |
| |
| * tests/run-test: New file. Run a test manually |
| |
| * tests/Makefile.am, tests/get_them: Moved automatically generated |

| |
| 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl> |
| |
| * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\ |
| wrap}.test: Added a few testcases. |
| |

| |
| * Prerelease 1.4h. |
| |
| * lib/Makefile.am (noinst_HEADERS): regex.h added |

| `C'. Reported by Ulrich Drepper. |
| |

| |
| 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl> |
| |
| * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of |
| ../COPYING. ../Makefile is a file which is certainly present when |
| test is executed in testSubDir. One can't be sure that the COPYING |
| file is in .. or ../.. in all situations, the ../Makefile is |
| always there. |
| |
| * doc/m4.texinfo (Include): adjusted expected test output |
| according to new tests, i.e. the input will always come from the |
| file `in' created by the test. |
| |
| * tests/Makefile.am: Added three lines at the top to get |
| esyscmd.1.test working. |
| |
| * tests/get-them: modified to generate clearer tests who will need |
| less maintenance when new test examples are created in |
| `doc/m4.texinfo'. All tests are small (nearly stand-alone, they |
| need the generic file `defs') shell scripts creating `in', `ok', |
| `out' and when apropriate `okerr' and `err' in the directory |
| `testSubDir' when executed. The compare of `ok' and `out' |
| (and of `okerr' and `err') will be the exit status of the test. |
| `out' must match `ok' (and `okerr' must match `err') for the test |
| to be succesful. |
| |
| * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for |
| the tests generated by tests/get-them getting it input normally |
| from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.' |
| (dot) before the numeric part) is reserved for all other (hand |
| written) tests. The `+' means one or more times. |
| |
| 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl> |

| |
| * src/numb.{c,h}: New files, implements multiple precision eval |

| Reported by Karl Berry. |
| |
| * Makefile.in (distclean, realclean): Instead of recursively |
| calling $(MAKE) for the -local part, allow parallel execution of |
| -recursive and -local, only delay the removal of config.status, |
| which is repeated in both goals. |
| |
| 1994-09-13 François Pinard <pinard@iro.umontreal.ca> |
| |
| * Release 1.3. |
| |
| * Makefile.in: Group all *clean-recursive goals in one, using sed |
| to remove `-recursive' while calling make recursively. Also, use |
| a subshell for each recursive $(MAKE). |
| Reported by Jim Meyering. |
| |
| * src/m4.h (memcpy): Define with bcopy for BSD systems. |
| Reported by Kaveh R. Ghazi. |
| |
| * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS |
| 4.1.3 requires -ldl to link even ansik2nr, and we need a way to |
| specify it. |
| |

| Reported by Jim Meyering. |
| |
| Solidify frozen files with respect to -P: |

| calling a function by that name. Declare the variable. |
| * src/m4.h: Adjust declaration for prefix_all_buitins. |
| * src/builtin.c (builtin_init): Merge in functionality from |
| previous prefix_all_buitins function, while making entries in the |
| symbol table, but not modifying the builtin description itself. |
| |
| * src/freeze.c (reload_frozen_state): Add a useless `break;', |
| because *many* compilers do not accept an empty `default:'. |
| Reported by Akiko Matsushita, Eric Backus, John David Anglin, |
| Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper. |
| |
| * configure.in: Use AC_TYPE_SIGNAL. |

| files. |
| * Makefile.in: Adjusted. |
| * configure.in: Configure new Makefiles. |

| |
| 1994-07-29 François Pinard <pinard@iro.umontreal.ca> |
| |
| * configure.in: If sigaction is available and SA_ONSTACK defined, |

| * Release 1.2 |
| |
| 1994-07-17 François Pinard <pinard@iro.umontreal.ca> |
| |
| * configure.in: Check for sigaction and sigvec. Add a new delayed |
| check for RLIMIT_STACK, combine in the checking for getrlimit. |
| All those things are not universally available. |
| * stackovf.c: Split setting up the trap handler and catching |

| 1994-07-15 François Pinard <pinard@iro.umontreal.ca> |
| |
| * Makefile.in: Modify so parallel make will not try making |
| lib/libm4.a twice simultaneously. |
| Reported by Jim Meyering. |
| |
| 1994-07-14 François Pinard <pinard@iro.umontreal.ca> |
| |
| * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in |
| error message, for when no code possibility exists. Even if this |
| line is completely #ifdef'ed out, it brings a syntax error. |
| Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco. |
| |
| * Makefile.in (install): Have install depend on all too, for lib |
| to be remade as needed. |
| |
| * examples/stackovf.sh: Try ksh, bsh and bash for shells |
| providing ulimit, instead of using only ksh. |
| Reported by Jim Avera and Joseph E. Sacco. |
| |
| 1994-07-12 François Pinard <pinard@iro.umontreal.ca> |
| |
| * Makefile.in (check): Have it depend on all instead of m4. In |
| this way, a change in lib will be detected and processed. |
| |
| * builtin.c (numeric_arg): Use strtol and verify the conversion, |
| instead of using sscanf which stops as soon as there is a |
| non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy) |
| and divert(1xyzzy) were all accepted without any warning or error |
| messages. |
| * m4.h: Declare strtol as long if not including stdlib.h. |
| * configure.in: Check for limits.h, and replace strtol if missing. |
| * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c. |

| Reported by Jim Meyering. |
| |
| 1994-07-06 Jim Avera <jima@netcom.com> |
| |
| * stackovf.c: Isolated OS-dependent sections; Improved portability, |
| adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal |
| handlers), and a default error message if the fault address is not |
| available (when neither siginfo.h nor BSD sigcontext are supported). |
| * configure.in: Changes for stackovf.h: Check for sigcontext, |
| sigaction, sigstack, and define rlim_t as int if necessary. |
| * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t. |
| * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow. |

| |
| 1994-07-02 François Pinard <pinard@iro.umontreal.ca> |
| |
| * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS, |
| because siginfo.h is unrelated to standard headers, and siginfo.h |
| is already checked for. |
| Reported by Joseph E. Sacco. |
| |
| * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by |
| PROTOTYPES. |
| * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by |
| AC_PROTOTYPES. |
| |
| 1994-06-29 François Pinard <pinard@iro.umontreal.ca> |
| |
| * builtin.c (substitute): Use \& to represent this part of the |
| string which was matched by the whole regexp, instead of |
| representing the whole string. Any usage of \0 issues a warning |
| and acts like \&, it will disappear in some subsequent release. |
| |
| 1994-06-27 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.c: Complete prototype for forwarded declaration of usage. |
| |
| * input.c (init_macro_token): Correct own reference in error |
| message. Previous name get_macro_func was referred to instead. |
| (next_char): Correct own reference in error message. Previous |
| name advance_input was referred to instead. |
| |
| * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits. |
| * eval.c (logical_or_term, logical_and_term, or_term, xor_term, |
| and_term, not_term, logical_not_term, cmp_term, shift_term, |
| add_term, mult_term, exp_term, unary_term, simple_term): Add |
| prototype to forwarded declarations. Declare parameter v1 as |
| eval_t * instead of int *. Same for local variable v2 in dyadic |
| functions. Same for result in exp_term. |
| * builtin.c (m4_eval): Declare value as eval_t instead of int. |
| (ntoa): Declare value as eval_t instead of int. Declare uvalue as |
| unsigned_eval_t instead of unsigned int. Change casts accordingly. |
| (shipout_int): Cast first argument of ntoa to eval_t. |
| Reported by Thorsten Ohl. |
| |
| * macro.c: Complete the prototypes of forwarded expand_macro and |
| expand_token. |
| Reported by Thorsten Ohl. |
| |
| * m4.h: Define voidstar as void * or char * depending on __STDC__. |

| * m4.c (xfree): Replace void * by voidstar. |
| Reported by Tom McConnell. |
| |

| * Makefile.in (DISTFILES): Distribute ansi2knr.1 |
| |
| * Makefile.in (stamp-h.in): Avoid running ./config.status if |
| stamp-h does not exist yet. This avoids running it a second time |
| just after the initial ./configure. |
| Reported by David MacKenzie and Tom McConnell. |
| |
| * m4.h: Replace the enum debug_info declaration with a series of |
| #define's. The Ultrix 3.1 compiler would otherwise need casting |
| (int) to most references, when used in expressions. |
| Reported by Tom McConnell. |
| |
| 1994-06-25 François Pinard <pinard@iro.umontreal.ca> |
| |
| * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES, |
| following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES |
| calls the compiler. Previously, FP_PROTOTYPES was only calling |
| the preprocessor; by not being subject to CFLAGS, this was |
| discouraging those flags asking for ANSI compilation. |
| * acconfig.h: Document HAVE_PROTOTYPES. |
| * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES. |
| * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__. |
| Reported by Eric Backus. |
| |
| * configure.in: Substitute CFLAGS and LDFLAGS, taking their value |
| from the environment. Default CFLAGS to -g if not set. |
| * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure. |
| * lib/Makefile.in: Have CFLAGS substituted from configure. |
| Reported by Eric Backus and Tom McConnell. |
| |
| * configure.in: m4_undefine changeword before using AC_ENABLE. |
| |
| * m4.h: Declare prototypes for error (for ANSI compilers only), |
| prefix_all_builtins and reference_error. |
| Reported by Tom McConnell. |
| |
| * input.c (set_word_regexp): Do not try to initialize the array |
| test from a string, this does not work with non-ANSI compilers. |
| Reported by Eric Backus. |
| |
| * Makefile.in (dist): Clean examples/ before saving it. |
| (distclean-local): Also remove stamp-h. |
| Reported by Eric Backus. |
| |
| * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with |
| non ANSI compilers. |
| Reported by Tom McConnell. |
| |
| * checks/Makefile.in (clean): Depends on mostlyclean. |
| (mostlyclean): New goal. |
| |
| 1994-06-24 François Pinard <pinard@iro.umontreal.ca> |

| Declare TOKEN_DATA_FUNC macro. |
| * builtin.c: Declare changeword. |
| (m4_changeword): New function. |
| * input.c: Include "regex.h", define variables with word regexps. |
| (input_init): Initialize the word regexp. |
| (set_word_regexp): New. |
| (next_token): Declare local variables, use the previous code if |
| default_word_regexp is true. Else, match using a new code. Save |
| the original text. |
| * macro.c (expand_token): Ship out original text if not a macro |
| name. |
| Reported by Krste Asanovic and Pete Chown. |
| |
| [These modifs all depend upon ENABLE_CHANGEWORD] |
| * m4.h: Declare external user_word_regexp. |
| * m4.c: Declare user_word_regexp, and initialize it from |
| --word-regexp or -W, or NULL if not specified. |
| * input.c: Use user_word_regexp if specified, instead of |
| DEFAULT_WORD_REGEXP. |
| |
| * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to |
| agree with it. |
| |
| * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o. |
| * checks/Makefile.in: Empty the suffix list. |
| Reported by Geoff Russell, Joel Sherrill and Roland McGrath. |

| * m4.c: Declare nesting_limit and initialize it to 250. |
| Implement -LNUMBER or --nesting-limit=NUMBER to change its |
| value. |
| * m4.h: Declare nesting_limit as external. |
| * macro.c (expand_macro): Stop execution whenever nesting limit |
| is exceeded. |
| Reported by Bengt Mertensson. |
| |
| * eval.c (evaluate): Diagnose excess characters in eval input. |
| Things like `eval(08)' used to return 0 with no diagnostic. |
| |
| * m4.h: Capitalize first letter of all macro arguments in |
| definitions. |
| |
| * m4.c: Declare warning_status, initialize it to 0. Add new |
| option -E, or --fatal-warnings, which sets warning_status to |
| EXIT_FAILURE instead. |
| * m4.h: Declare external warning_status. Define EXIT_SUCCESS and |
| EXIT_FAILURE if not otherwise done by header files. |
| * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE. |
| * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c, |
| eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first |
| argument of all M4ERROR calls. |
| Reported by Noah Friedman. |

| * examples/incl-test.m4: Renamed from incl_test.m4. |
| * examples/include.m4: Include incl-test.m4 instead of |
| incl_test.m4. |
| * examples/multiquotes.m4: Renamed from multi-quotes.m. |
| |
| 1994-06-22 François Pinard <pinard@iro.umontreal.ca> |
| |
| * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note |
| that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and |
| also tested it on a Sun Sparc workstation running SunOS 4.x. |
| |
| * format.c (format): When not HAVE_EFGCVT, m4 was failing the |
| 49.format check, abusing a `union values' argument with sprintf |
| without selecting the proper field. Now, save the formatting type |
| first, delaying the fetch of the corresponding argument. |
| Reported by Joseph E. Sacco and Tom Quinn. |
| |
| * format.c (format): Remove const from char *fmt declaration when |
| not HAVE_EFGCVT, because a NUL may be forced into it. |
| |
| * m4.h: Declare atof() when not STDC_HEADERS. |
| Reported by Joseph E. Sacco. |
| |
| * Regenerate configure using Autoconf 1.11, this corrects a |
| problem about an incorrect cpp seting on NeXT 3.1. |
| Reported by Alexander Lehmann. |
| |
| 1994-06-05 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.h (_): Change argument from `x' to `Args'. |

| 1994-04-22 Jim Avera <jima@netcom.com> |
| |
| * stackovf.c: New file implementing stack-overflow detection. |

| Reported by Jim Meyering. |
| |
| 1994-01-25 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.h: Move the conditional definition of volatile after the |
| inclusion of system files, because they may define it first. |
| |
| 1994-01-04 François Pinard <pinard@iro.umontreal.ca> |

| * builtin.c, output.c: Use errno as second parameter to error, |
| instead of using syserr() with %s. |

| instead of before, which eases M-x next-error processing. |
| |
| 1993-11-24 François Pinard <pinard@iro.umontreal.ca> |
| |

| expected is on the left and the obtained on the right. |
| |
| * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR |

| warning with WARNING*, fatal with FATAL* and internal_error with |
| INTERNAL_ERROR*. |
| * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist, |
| this is not needed anymore. |
| |
| * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and |

| Delete debug_print and debug_message routines, add |
| debug_message_prefix routine. |

| This is still a beta release for the future GNU m4 version 1.1. |
| |
| * lib/alloca.c: New, from elsewhere. |
| * lib/Makefile.in: Distribute it. Define and use $(ALLOCA). |
| |
| * m4.h: Do not define index/rindex if already defined. If |
| FALSE/TRUE are already defined, do not redefine them, but merely |
| define boolean typedef to int. |
| |
| * Makefile.in: Use $(DEFS) while compiling ansi2knr. |
| * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS, |

| __GNUC__ and once for __STDC__. |
| * lib/regex.h: Leave const alone, AC_CONST will take care of it. |
| |
| * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for |

| * Makefile.in: Remove references to version.h. |
| |
| * output.c (shipout_text): Centralize all `#line NUM ["FILE"]' |
| production, by using a simpler and more robust algorithm. This |
| solves the problem of synclines sometimes written in the middle of |
| an output line. Delete sync_line() and output_lines variable. |
| * m4.h: Remove sync_line prototype and output_lines declaration. |
| * input.c (next_char), output.c (shipout_text): Remove references |
| to output_lines. |
| * input.c (push_file, pop_file): Merely put the value -1 in |
| output_current_line instead of calling sync_line, for delaying a |
| single `#line NUM FILE' before next output line. Do not test |
| for sync_output, because this is unnecessary clutter. |
| * output.c (make_divertion, insert_divertion): Idem. |
| * input.c: Rename must_advance_line to start_of_input_line, for |
| consistency. |
| |
| * debug.c (trace_header): Select a new debug line format, which |
| better complies with GNU standards for formatting error messages. |
| With option `-dfl', M-x next-error might be used on the output. |
| * m4.c (vmesg): Adjust format of error output to GNU standards. |
| * m4.texinfo: Adjust examples for `make check' to work. |
| |
| * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper |
| case for enum debug_info constants, which were all lower case. |
| |
| * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of |
| re_search_2. |
| * lib/regex.[ch]: Use new version from textutils 1.3.6, with some |
| collected patches. I tried a few times using newer regex.[ch], it |
| mysteriously stopped aborting with this one. Insecure feeling... |
| * lib/Makefile.in: Distribute regex.[ch].old, just in case! |
| |
| 1992-12-18 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.c: Change `--no-warnings' to `--silent'. |
| Reported by David MacKenzie. |
| |
| * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and |
| leave it off for now. See comment in m4.c for justification. |
| Reported by David MacKenzie. |
| |
| * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h). |
| * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H. |
| |
| * Makefile.in: Add a new `info' goal. Use macro MAKEINFO. |
| |
| * Makefile.in: Ensure recursive cleaning is done before local |
| cleaning for all clean goals. |
| |
| * builtin.c (ntoa): Ensure the value is always interpreted as a |
| signed quantity, whatever the radix is. |
| |
| 1992-11-18 Jim Meyering <meyering@idefix> |

| * Makefile.in: Add $(AWK) to MDEFINES. |
| * checks/Makefile.in: Transmit $(AWK) to get_them. |
| * checks/get_them: Use $AWK instead of gawk. Add a close in the |
| awk script when switching files, because without this, mawk runs |
| out of file descriptors. |
| |
| 1992-11-16 François Pinard <pinard@iro.umontreal.ca> |
| |
| * Makefile.in (realclean): Delete m4.info*. |
| Reported by Jim Meyering. |
| |
| * Makefile.in: Adjust and link with checks/Makefile. |

| recognizable by next-error, also use a better message. |
| |
| 1992-11-16 Jim Meyering <meyering@idefix> |
| |
| * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.' |
| And use that only if __GNUC__ since we're using it's GCC-specific |
| semantics that tell the compiler the associated function doesn't |
| return. |
| |
| * builtin.c (substitute): Don't use character as an array index. |
| (dumpdef_cmp): Make formal arguments `const void *' to avoid |
| warnings with gcc -W -Wall on systems with qsort prototype. |
| (m4_errprint): Cast obstack_finish to `char *' to avoid warnings |
| from gcc -W -Wall. |
| |
| * eval.c (most functions): Add parentheses to assignments used |
| as truth values go avoid warnings from gcc -Wall. |
| |
| * input.c, m4.c, output.c, path.c, symtab.c: Declare static |
| any functions that don't need external scope. |
| |
| * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c |
| (many functions and arrays): Declare `const'. |
| |
| 1992-11-15 François Pinard <pinard@iro.umontreal.ca> |

| removing the declaration from m4.h. Also rename false to FALSE |
| and true to TRUE. |
| |

| |
| * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not |
| so heavily loaded. It gets more easily overridable, calling make. |
| Reported by Jim Meyering. |
| |
| * Makefile.in (dist): Get .fname from the current directory name, |
| instead of from version.h. I need updating many files manually, |
| when the version changes, version.h is just one of them. |
| |
| 1992-11-14 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.h: Remove the tag `boolean' on the enum introducing typedef |
| `boolean'. This tag conflicts with <sys/types.h> on SVR4. |
| Reported by Tom McConnell. |
| |
| 1992-11-13 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.texinfo: Correct the examples for 33.divert, 38.divnum, |
| 39.cleardiv, which were describing missing or spurious newlines. |
| Modify examples 52.eval, 53.esyscmd and 54.sysval so the results |
| do not depend on machine word size, `/bin/false' implementation, |
| or `wc' output format. `make check' is more dependable, now. |
| |
| * checks/check_them: Summarize the failed tests by listing their |
| name, at end. If none, issue `All checks successful'. Output |
| `Checking' instead of `Input file:'. |
| |
| * checks/get_them, checks/check_them: Reindented. |
| |
| * Makefile.in (dist): chmod a+r before making the tar file. |
| |
| 1992-11-12 François Pinard <pinard@iro.umontreal.ca> |
| |
| * builtin.c (m4_dnl): Diagnose any parameter to `dnl'. |
| |
| * input.c (next_token): Reinitialize token_buttom just after using |
| it as a watermark with obstack_free. Or else, a future token, big |
| enough for triggering reallocation of the obstack chunk, could |
| void the initialized value of token_buttom, later causing panic in |
| obstack_free. Rename token_buttom to token_bottom everywhere. |
| |
| * m4.h: Before declaring errno, first include <errno.h> and |
| ensure that it does not define errno. |
| Reported by Richard Stallman. |
| |
| 1992-11-11 François Pinard <pinard@iro.umontreal.ca> |
| |
| * builtin.c: Define and use DECLARE macro for builtins. |

| argument, this is a common idiom for introducing long comments. |
| |
| * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing |
| arguments. The last argument was silently ignored. |
| |
| * m4.c (cmd_error): Add a missing semicolon before va_end(). |
| |
| 1992-11-10 François Pinard <pinard@iro.umontreal.ca> |
| |

| Compile and use ansi2knr with old compilers. Update DISTFILES. |
| Add `aclocal.m4' to `configure' dependencies. |
| * ansi2knr.c: New, from Ghostscript distribution. |
| * configure.in: Define U through FP_PROTOTYPES for old compilers. |
| Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T. |
| * aclocal.m4: New, provide FP_PROTOTYPES. |
| * m4.h: Conditionnaly protoized through Args, save for varags. |
| * builtin.c: Protoized. Then: |

| (xfree): Accept void * instead of char *. |
| (xmalloc): Return void * instead of char *. |
| (xrealloc): Accept and return void * instead of char *. |
| * macro.c: Protoized. |
| * output.c: Protoized. |
| * path.c: Protoized. Then cast some (char *) over xmalloc's. |
| * symtab.c: Protoized. |
| |
| 1992-11-06 François Pinard <pinard@iro.umontreal.ca> |
| |
| * m4.texinfo: Remove directory from diagnostics in 30.include, |
| 51.eval, 56.errprint and 57.m4exit tests. |
| |
| * m4.h: Remove declarations for int or void system functions, they |
| cause more conflicting trouble than they make good. |
| |
| * configure.in: Avoid configuration header file. Add some tests. |
| * m4.h: Remove #include "config.h". |
| * Makefile.in, lib/Makefile.in: Implement Autoconf interface. |
| Then, rewritten for better compliance with GNU standards. |
| |
| 1992-11-05 François Pinard <pinard@iro.umontreal.ca> |
| |
| * format.c (format): Avoid syntax error if not HAVE_EFGCVT, |

| Reported by Jason Merrill. |
| |
| * Delete .vers, etc/newdist.sh, etc/newvers.sh and |

| 1992-03-10 François Pinard <pinard@iro.umontreal.ca> |
| |
| * Makefile.in (check): Add m4 as dependency. |
| |
| * m4.c: Accept --no-warnings instead of --no_warnings, and |
| --no-gnu-extensions instead of --no_gnu_extensions. Make the |
| usage message more informative. |
| Reported by David MacKenzie. |
| |

| François Pinard and Roland H. Pesch for providing me with reports. |
| |
| * The builtins incr and decr are now implemented without use of |
| eval. |
| |
