[bitbake][walnascar][2.12][PATCH 1/2] Use a "fork" multiprocessing context

[Steve Sakoman]

From: Joshua Watt <JPEWhacker@gmail.com>

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

Re: [bitbake-devel] [bitbake][walnascar][2.12][PATCH 2/2] bitbake: Bump version to 2.12.1

[Martin Jansa]

Hello Steve,

I've noticed today that 1.12.3 tag was pushed for current 1.12 branch:

commit 710f98844ae30416bdf6a01b655df398b49574ec (tag: yocto-5.2.3,
tag: 2025-04.3-walnascar, tag: 2.12.3, origin/2.12, oe/2.12,
github/2.12, github.oe/2.12, 2.12)
Author: Richard Purdie <richard.purdie@linuxfoundation.org>
Date:   Tue Jul 29 16:42:25 2025 -0400

    utils: Optimise signal/sigmask performance

Should I redo this as 2.12.4 and adjust the related change for oe-core
to bump the minimal version to 2.12.4 as well?

Similarly for scarthgap and 2.8 bitbake, which has 2.8.12 tag already,
so instead of 2.8.1 I would bump it to 2.8.13.

commit 982645110a19ebb94d519926a4e14c8a2a205cfd (tag: yocto-5.0.12,
tag: 2024-04.12-scarthgap, tag: 2.8.12, origin/2.8, oe/2.8,
github/2.8, github.oe/2.8, 2.8)

Adding Richard since he is the bitbake maintainer.

I'm not sure what has been done historically.  We haven't been bumping
the version with each minor release, but it seems to make sense to me
to do the bump to 2.12.4 rather than 2.12.1

Re: [bitbake-devel] [bitbake][walnascar][2.12][PATCH 2/2] bitbake: Bump version to 2.12.1

[Martin Jansa]

I've sent the v2 of all 4 related changes to use 2.12.4 and 2.8.13.

I've also noticed that the sanity check for bitbake version is
executed too late after the utils.py is already failing with:
ERROR: Unable to parse oe-core/meta/lib/oe/utils.py
Traceback (most recent call last):
  File "oe-core/meta/lib/oe/utils.py", line 11, in <module>
    from bb import multiprocessing
ImportError: cannot import name 'multiprocessing' from 'bb'
(bitbake/lib/bb/__init__.py)

To avoid this issue I recommend to leave "lib/oe/utils: use
multiprocessing from bb" commit in oe-core scarthgap and walnascar for
some future batch and now merge just the bitbake version bump in
bitbake and the requirement for newer bitbake in oe-core, that way
people will hopefully update both before it gets really mandatory.

Cheers,

I'll be doing the final walnascar build at the end of next week, so we
either need to have this sorted by early next week, or just decide to
leave things as they are with walnascar since it is going end of life.

I'll pull the patches from scarthgap till we sort the proper version
numbering and we can then stage them as you suggest.

Sorry about the delay.

Your patches are right and the tags are messed up. They're getting
