Other changes include: - Refreshing all necessary patches for 3.7.0 - Add a hash for the license file. - Python no longer has it's own internal libffi, as such, host-libffi is now required to build host-python3, and is added as a dependency. - Drop PYTHON3_LIBTOOL_PATCH = NO, since there is no longer any internal libffi copy that was causing the libtool patching process to fail. - A new core module "uuid" is now is added in the Config.in file, and relies on util-linux's uuid library. - Also, a new patch: 0030-Fix-cross-compiling-the-uuid-module.patch is required to fix compiling the uuid module, because the include directory search path for uuid.h is hardcoded to /usr/include/uuid, which causes an "unsafe for cross-compilation" error during compiling if the host pc has uuid headers installed. - 0031-Add-an-option-to-disable-uuid-module.patch is added to allow disabling the Python3 UUID module, so that when BR2_PACKAGE_PYTHON3_UUID is disabled by the UUID library is present, the uuid Python module is not built, as expected. - 0032-fix-building-on-older-distributions.patch is added to change os.replace by os.rename in the update_file.py script to fix building on older Linux distributions that have older versions of python that don't include os.replace. os.rename acts in the same way as os.replace, but is cross-platform compatible. Because Buildroot is guaranteed to be built in a POSIX environment, it is safe to change replace to rename.

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
