Add distutils 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.
|
||
|
|
|
||
|
|
For the Python standard library, our Python 3 package already contains
|
||
|
|
a patch named python3-004-old-stdlib-cache.patch, which allows to
|
||
|
|
disable the PEP 3147 installation.
|
||
|
|
|
||
|
|
But that lives the distutils/setuptools package an unsolved
|
||
|
|
problem. This patch therefore adds a new patch to Python, which makes
|
||
|
|
distutils package use the traditional installation path when byte
|
||
|
|
compiling, rather than the PEP 3147 installation path. Since
|
||
|
|
setuptools relies on distutils internally, it also fixes setuptools
|
||
|
|
based packages.
