Vaughan <gary@gnu.org> - - * config/mailnotify: New file for mailing commit notifications, - imported from cvs-utils. - * 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/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. - * m4/output.c (m4_output_init): Likewise. - * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise. - * m4/syntax.c (remove_syntax_attribute): Likewise. - * src/freeze.c (reload_frozen_state): Likewise. - * src/main.c (main): Likewise. - -2003-10-07 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.

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.

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.

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.

Vaughan <gary@gnu.org> - - 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.

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.

Vaughan <gary@gnu.org> - - 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.

Vaughan <gary@gnu.org> - - * doc/STYLE: Added notes on callback naming schemes. - - * m4/module.c (m4_set_module_macro_table) - (m4_set_module_builtin_table): Declarations weren't changed when - definitions were renamed on 2003-06-19. - - * m4/hash.c (m4_hash_resize): ifdefed out. This function is - neither used nor particularly appropriate since it exposes the - internal workings of the hash module. I haven't yet decided - whether to remove it entirely. - -2003-06-20 Gary V. Vaughan <gary@gnu.org> - - 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.

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.

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.

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.

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.

Vaughan <gary@gnu.org> - - 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. - -2001-09-18 Gary V. Vaughan <gary@gnu.org> - - 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.

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.

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> - - * modules/stdlib.c, modules/times.c: Misc cleanups. - -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.

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.

Vaughan <gary@gnu.org> - - The experimental `changeword' feature never took off, and has - no obvious advantages over `changesyntax' to compensate the - enormous speed penalty it carries: - * configure.in (ENABLE_CHANGEWORD): Removed. - * m4/m4module.h (m4_set_word_regexp): Removed. - * m4/m4private.h (m4_token_data): Removed original_text field. - * m4/utility.c (m4_token_data_orig_text): Removed. - * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code. - * m4/macro.c: Ditto. - * src/main.c: Ditto. - * modules/Makefile.am (changeword.la): Removed. - * modules/changeword.c: File removed. - * doc/m4.texinfo: References to changeword and --word-regexp - 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 - config/Makefile.am. - * config/Makefile.am (STANDARD_MACROS): Rename as... - (ACLOCAL_MACROS): this. - (list-standard-macros): Remove. - (spy): New. - -2001-08-29 Gary V.

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.

Vaughan <gary@gnu.org> - - * 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.

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.

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. - - * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one - argument, this is a common idiom for introducing long comments. - - * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing - arguments.
