* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

* | Issue #25791: Warn when __package__ != __spec__.parent.Brett Cannon2016-01-221-4/+14
| | | | | | | | | | | | | | | | | | In a previous change, __spec__.parent was prioritized over __package__. That is a backwards-compatibility break, but we do eventually want __spec__ to be the ground truth for module details. So this change reverts the change in semantics and instead raises an ImportWarning when __package__ != __spec__.parent to give people time to adjust to using spec objects.

| | | | | | | | | | | | | | | | | | importlib.abc.Loader.exec_module() is also defined. Before this change, create_module() was optional **and** could return None to trigger default semantics. This change now reduces the options for choosing default semantics to one and in the most backporting-friendly way (define create_module() to return None).

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | #17115,17116: Have modules initialize the __package__ and __loader__Brett Cannon2013-05-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
