* Issue #15767: Touch up ModuleNotFoundError usage by import.Brett Cannon2013-06-133-6/+26
| | | | | | | | | | | | | Forgot to raise ModuleNotFoundError when None is found in sys.modules. This led to introducing the C function PyErr_SetImportErrorSubclass() to make setting ModuleNotFoundError easier. Also updated the reference docs to mention ModuleNotFoundError appropriately. Updated the docs for ModuleNotFoundError to mention the None in sys.modules case. Lastly, it was noticed that PyErr_SetImportError() was not setting an exception when returning None in one case. That issue is now fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | ImportError. The exception is raised by import when a module could not be found. Technically this is defined as no viable loader could be found for the specified module. This includes ``from ... import`` statements so that the module usage is consistent for all situations where import couldn't find what was requested. This should allow for the common idiom of:: try: import something except ImportError: pass to be updated to using ModuleNotFoundError and not accidentally mask ImportError messages that should propagate (e.g. issues with a loader). This work was driven by the fact that the ``from ... import`` statement needed to be able to tell the difference between an ImportError that simply couldn't find a module (and thus silence the exception so that ceval can raise it) and an ImportError that represented an actual problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | importlib.abc.Loader.init_module_attrs() and implement importlib.abc.InspectLoader.load_module(). The importlib.abc.Loader.init_module_attrs() method sets the various attributes on the module being loaded. It is done unconditionally to support reloading. Typically people used importlib.util.module_for_loader, but since that's a decorator there was no way to override it's actions, so init_module_attrs() came into existence to allow for overriding. This is also why module_for_loader is now pending deprecation (having its other use replaced by importlib.util.module_to_load). All of this allowed for importlib.abc.InspectLoader.load_module() to be implemented. At this point you can now implement a loader with nothing more than get_code() (which only requires get_source(); package support requires is_package()). Thanks to init_module_attrs() the implementation of load_module() is basically a context manager containing 2 methods calls, a call to exec(), and a return statement.

* | #17115,17116: Have modules initialize the __package__ and __loader__Brett Cannon2013-05-042-182/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | attributes to None. The long-term goal is for people to be able to rely on these attributes existing and checking for None to see if they have been set. Since import itself sets these attributes when a loader does not the only instances when the attributes are None are from someone overloading __import__() and not using a loader or someone creating a module from scratch. This patch also unifies module initialization. Before you could have different attributes with default values depending on how the module object was created. Now the only way to not get the same default set of attributes is to circumvent initialization by calling ModuleType.__new__() directly.
