d2afa01f76
Update all appropriate version numbers as well as SHAs and MD5s as well
as repbasing BR's patches on top of 3.6.1 codebase (new github repo
tree, v3.6.1 tag was used). Note that patch:
[PATCH] Change the install location of _sysconfigdata.py
was dropped due to the fact taht build system now adds platform
specific suffix to sysconfigdata's name, so each platform's file
should have a unique name and distutils now allows to specify which
sysconfigdata is used via _PYTHON_SYSCONFIGDATA_NAME
see:
c4b53afce4
92dec548ff
and patches:
[PATCH] distutils/sysconfig: use sysconfigdata
[PATCH] setup.py: do not add invalid header locations
[PATCH] Do not harcode invalid path to ncursesw headers
was dropped since it looks like it made it's way upstream, see:
409482251b
1351c31aa9
e13c3201fb
respectively.

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
