bpo-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. (GH-6834)

2018-06-16T04:40:56+00:00

In some development setups it is inconvenient or impossible to write bytecode
caches to the code tree, but the bytecode caches are still useful. The
PYTHONPYCACHEPREFIX environment variable allows specifying an alternate
location for cached bytecode files, within which a directory tree mirroring the code
tree will be created. This cache tree is then used (for both reading and writing)
instead of the local `__pycache__` subdirectory within each source directory.

Exposed at runtime as sys.pycache_prefix (defaulting to None), and can
be set from the CLI as "-X pycache_prefix=path".

Patch by Carl Meyer.

bpo-33169: Remove values of `None` from sys.path_importer_cache when invalidating caches (GH-6402)

2018-04-06T23:10:18+00:00

An entry of None in sys.path_importer_cache represents a negative/missing finder for a path, so clearing it out makes sense.
