Subject: [PATCH] Always generate legacy bytecode (allows removal of py source
|
|
code)
|
|
|
|
We want to create compiled bytecode for modules in the read-only
|
|
squashfs, and we also want to avoid distributing the py source code
|
|
which is a waste of space.
|
|
|
|
Unfortunately, after PEP3147, it's no longer possible to distribute
|
|
pyc bytecode without the corresponding py source code unless the
|
|
bytecode is generated using the "legacy" layout (ie. not using __pycache__).
|
|
|
|
Since all packages process their Python source code in different ways,
|
|
but ultimately all compile it via a call to py_compile.compile(), the
|
|
easiest solution is to patch py_compile.compile() so that it only
|
|
generates legacy bytecode.
