gh-125714: Doc: Explain that multiprocessing only supports unpicklable functions through the fork method #125750
base: main
Are you sure you want to change the base?
Conversation
… through the fork method In multiprocessing and concurrent.futures's documentations, as well as the release notes for Python 3.14. This moves the paragraph in 3.14's release notes from the deprecations section to 'Porting to Python 3.14' because it is a breaking change, which follows a deprecation in Python 3.12. This explicitly mentions `PicklingError` in this section, so it is easy to find for somehow who gets the error and searches its name through the page.

I am afraid you will have to sign the CLA. |
I already did by submitting this PR after accepting Github's terms of service:
Nonetheless, I'm fine with the CLA on principle, but I'm not willing to give out the personal info the cla-bot or the form are asking for. |
