The old platform-specific contents of importdl.c, broken down into one file per platform (really: per style of Dl API; e.g. all platforms using dlopen() are grouped together in dynload_shlib.c.). This is part of a set of patches by Greg Stein. 1999-12-20 21:18:49 +00:00

Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py. This introduces a new function, imp.extension_suffixes(), which is currently undocumented. That is forthcoming once issue #14657 is resolved and how to expose file suffixes is decided. 2012-05-04 15:20:40 -04:00			`const char *_PyImport_DynLoadFiletab[] = {".o", NULL};`

PEP 489: Multi-phase extension module initialization Known limitations of the current implementation: - documentation changes are incomplete - there's a reference leak I haven't tracked down yet The leak is most visible by running: ./python -m test -R3:3 test_importlib However, you can also see it by running: ./python -X showrefcount Importing the array or _testmultiphase modules, and then deleting them from both sys.modules and the local namespace shows significant increases in the total number of active references each cycle. By contrast, with _testcapi (which continues to use single-phase initialisation) the global refcounts stabilise after a couple of cycles. 2015-05-23 22:24:10 +10:00			`dl_funcptr _PyImport_FindSharedFuncptr(const char *prefix,`

dynload_dl.c: replace tabs by spaces 2011-02-23 11:29:28 +00:00			`char funcname[258];`
Cleanup patches from Greg Stein: * in import.c, #ifdef out references to dynamic loading based on HAVE_DYNAMIC_LOADING * clean out the platform-specific crud from importdl.c. [ maybe fold this function into import.c and drop the importdl.c file? Greg.] * change GetDynLoadFunc's "funcname" parameter to "shortname". change "name" to "fqname" for clarification. * each GetDynLoadFunc now creates its own funcname value. WARNING: as I mentioned previously, we may run into an issue with a missing "_" on some platforms. Testing will show this pretty quickly, however. * move pathname munging into dynload_shlib.c 1999-12-22 14:09:35 +00:00
