delta/cpython-git.git/Python/importlib_external.h, branch benjamin-eval-loop-edit github.com: python/cpython.git bpo-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. (GH-6834) 2018-06-16T04:40:56+00:00 Carl Meyer carl@oddbird.net 2018-06-16T04:40:56+00:00 b193fa996a746111252156f11fb14c12fd6267e6 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.

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

* Added new opcode END_ASYNC_FOR.
* Setting global StopAsyncIteration no longer breaks "async for" loops.
* Jumping into an "async for" loop is now disabled.
* Jumping out of an "async for" loop no longer corrupts the stack.
* Simplify the compiler.
