* Issue #15316: Let exceptions raised during imports triggered by theBrett Cannon2012-08-241-4/+14
| | | | | | | | | | | | | | | fromlist of __import__ propagate. The problem previously was that if something listed in fromlist didn't exist then that's okay. The fix for that was too broad in terms of catching ImportError. The trick with the solution to this issue is that the proper refactoring of import thanks to importlib doesn't allow for a way to distinguish (portably) between an ImportError because finders couldn't find a loader, or a loader raised the exception. In Python 3.4 the hope is to introduce a new exception (e.g. ModuleNotFound) to make it clean to differentiate why ImportError was raised.

* Issue #15715: Ignore failed imports triggered by the use of fromlist.Brett Cannon2012-08-171-2/+7
| | | | | | | | | | | When the fromlist argument is specified for __import__() and the attribute doesn't already exist, an import is attempted. If that fails (e.g. module doesn't exist), the ImportError will now be silenced (for backwards-compatibility). This *does not* affect ``from ... import ...`` statements. Thanks to Eric Snow for the patch and Simon Feltman for reporting the regression.

| | | | | | | | | | | | Lib/imp.py for imp.source_from_cache() instead of its own C version. Also change PyImport_ExecCodeModuleObject() to not infer the source path from the bytecode path like PyImport_ExecCodeModuleWithPathnames() does. This makes the function less magical. This also has the side-effect of removing all uses of MAXPATHLEN in Python/import.c which can cause failures on really long filenames.

* Issue #13959: HaveBrett Cannon2012-05-111-5/+9
| | | | | | | | | | importlib.abc.FileLoader.load_module()/get_filename() and importlib.machinery.ExtensionFileLoader.load_module() have their single argument be optional as the loader's constructor has all the ncessary information. This allows for the deprecation of imp.load_source()/load_compile()/load_package().

| | | | | | | | | | | importlib.machinery that provide the suffix details for import. The attributes were not put on imp so as to compartmentalize everything importlib needs for setting up imports in importlib.machinery. This also led to an indirect deprecation of inspect.getmoduleinfo() as it directly returned imp.get_suffix's returned tuple which no longer makes sense.

Also changed the meaning of None in sys.path_importer_cache to represent trying sys.path_hooks again (an interpretation of previous semantics). Also added a warning for when None was found. The long-term goal is for None in sys.path_importer_cache to represent the same as imp.NullImporter: no finder found for that sys.path entry.
