extend python3 manifest to add a module

extend python3 manifest to add a module

Hello,

I'm building an image on the dunfell branch.
I would like to add dataclasses module in python3. For that I know that 
I should add it to the python3-manifest.json.
I tried to add my new manifest file in SRC_URI using a bbappend. It 
didn't work as the manifest file is red by a anonymous python function 
on parsing:

filename = os.path.join(d.getVar('THISDIR'), 'python3', 
'python3-manifest.json')

What should I do to add dataclasses to my python3 installation? What is 
the suggested method or best practice for that operation?
I would like to avoid forking openembedded-core just for that.

Thank you

Perceval

The manifest simply defines how the packages are split up, the dataclasses module is always packaged.

For some reason, it appears to be part of python3-profile in my build:

$ oe-pkgdata-util find-path /usr/lib/python3.12/dataclasses.py
python3-profile: /usr/lib/python3.12/dataclasses.py

That’s not right though, we should put that in a better package.

It seems that the dataclasses is not packaged in a dedicated package on 
the dunfell branch according to sources here  
<https://git.openembedded.org/openembedded-core/tree/meta/recipes-devtools/python/python3/python3-manifest.json?h=dunfell>

So it ends up in python3-misc which have a lot of things:
$ oe-pkgdata-util find-path /usr/lib/python3.8/dataclasses.py
python3-misc: /usr/lib/python3.8/dataclasses.py

Should we package it in a dedicated package or another one? What would 
you suggest?

For master I just sent a patch moving it into -core, because it’s a fairly fundamental package.

For dunfell, moving it now is probably not a great idea, but at least you know now what package to RDEPEND on to get the class.

(or, you can RDEPEND on python3-modules and you get the entire standard library)
