bitbake: Use a "fork" multiprocessing context

mirror of https://git.yoctoproject.org/poky synced 2026-07-16 15:57:04 +00:00

Python 3.14 changes the default multiprocessing context from "fork" to
"forkserver"; however bitbake heavily relies on "fork" to efficiently
pass data to the child processes. As such, make "fork" context in the bb
namespace and use it in place of the normal multiprocessing module.

Note that multiprocessing contexts were added in Python 3.4, so this
should be safe to use even before Python 3.14
