* modules: huge simplification of module loading without libltdl.Gary V. Vaughan2013-09-211-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libltdl is huge and slow, and carrying the weight of support for decades old systems. We can do much better using POSIX dlopen and dlsym directly, simplifying and speeding up as we do so. * configure.ac (LT_CONFIG_LTDL_DIR, LTDL_INIT): Remove. (M4_DEFAULT_PRELOAD): Set to ""; we lost preload support along with removing libltdl. * Makefile.am: Don't include ltdl/Makefile.inc. (AM_CPPFLAGS): Manually add current directory to include search paths. * m4/m4private.h (includes): Remove ltdl.h. (INIT_SYMBOL, m4__module_init): Remove. (struct m4_module): Change handle type from lt_dlhandle to void *. * m4/m4module.h (M4INIT_HANDLER): Remove. * m4/module.c (includes): Add dlfcn.h. (m4__module_interface, iface_id, m4__module_init, module_dlerror): Remove. (m4__module_open): Drastically simplified without all the libltdl setup and interface id twiddling. Just call dlopen to get a native handle, and the dlsym to get the init function. (m4_module_import): Similarly wrt dlsym. * m4/path.c (FILE_SUFFIXES): Replace .la and LT_MODULE_EXT with hardcoded ".so". (m4_load_filename): Likewise. * modules/gnu.c: Remove libltdl preprocessor symbol renaming, and use "include_<modulename>" as the single entry point function. * modules/import.c, modules/m4.c, modules/modtest.c, modules/mpeval.c, modules/shadow.c, modules/stdlib.c, modules/time.c, modules/traditional.c: Likewise. * main.c (main): Remove calls to m4__module_init and LTDL_SET_PRELOADED_SYMBOLS. * tests/m4.in: Make sure we always have the modules/.libs and tests/.libs directories at the front of M4PATH so that the tests will find the modules they need to include.

* modules: remove support for module unload and refcount.Gary V. Vaughan2013-09-201-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Module management is horrifically more complex than it needs to be for the simple purpose of providing a means to implement new builtins using C. Fussing about reference counting or needing to maintain and test a facility to unload modules is an easy 600 lines to cut as a start at simplification. * src/main.c (main): Don't call m4__module_exit to unload all modules just prior to exiting the application. * m4/m4private.h (FINISH_SYMBOL, m4_module:refcount) (m4__module_exit, m4_module_refcount): Remove. (m4__module_next): Rename from this... * m4/m4module.h (m4_module_next): ...to this. Adjust all callers. (M4FINISH_HANDLER, m4_module_finish_func, m4_module_makeresident) (m4_module_refcount, m4_module_unload, m4_module_exit): Remove. * m4/m4module.c (m4__module_next): Rename from this... (m4_module_next): ...to this. (module_remove, m4_module_makeresident, m4_module_unload) (m4_module_exit, m4_module_refcount): Remove. * modules/load.c: Remove. (m4modules): Move from here... * modules/gnu.c (m4modules): ...to here. Update all callers. (M4FINISH_HANDLER(gnu)): Remove. * modules/m4.c (M4INIT_HANDLER(m4)): Remove. * modules/modtest.c (M4FINISH_HANDLER(modtest)): Remove. * modules/shadow.c (M4INIT_HANDLER(shadow)): Rewrite to work without refcount. * Makefile.am (pkglib_LTLIBRARIES): Remove modules/load.la. (modules_load_la_LDFLAGS, modules_load_la_LIBADD): Remove. * tests/modules.at: Remove references to load module, and tests of unload builtin. * tests/options.at: Remove obsolute finish hook and module unload trace output. * doc/m4.texi (Unload, Refcount): Remove. (M4modules): Change module reference from load to gnu. Signed-off-by: Gary V. Vaughan <gary@gnu.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
