[3.7] bpo-33169: Remove values of `None` from sys.path_importer_cache when invalidating caches (GH-6402) (GH-6403) 2018-04-07T00:02:18+00:00 Brett Cannon brettcannon@users.noreply.github.com 2018-04-07T00:02:18+00:00 a09bb87c1eebb07b01b8105cf536704893aec565 An entry of None in sys.path_importer_cache represents a negative/missing finder for a path, so clearing it out makes sense.

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.
