Subject: [PATCH] Add importlib fix for PEP 3147 issue
|
|
|
|
Python 3 has a new standard for installing .pyc file, called PEP
|
|
3147. Unfortunately, this standard requires both the .py and .pyc
|
|
files to be installed for a Python module to be found. This is quite
|
|
annoying on space-constrained embedded systems, since the .py file is
|
|
technically not required for execution.
|
|
|
|
This patch changes cache_from_source() and source_from_cache() in
|
|
importlib to get rid of the "__pycache__" directory.
|
|
This effectively disables PEP 3147 for:
|
|
|
|
* The python standard library
|
|
* Packages built with distutils or setuptools
|
|
* Packages built with automake that use the `py-compile` helper
|
