[PATCH v2 0/2] add basic b4 config file

[PATCH v2 0/2] add basic b4 config file

[Quentin Schulz]

This adds very basic support for using b4 in OE-Core. This essentially
just automatically adds the proper mailing list when running b4 prep
--auto-to-cc.

This also adds the b4 wrapper script that poky will need to use in order
to identify which mailing list a patch needs to be sent to and do some
additional per-patch checks that aren't necessary when running from
vanilla OE-Core.

Once this is merged, poky will need to merge OE-Core into itself and
override with its own .b4-config that makes use of that script.

Changes in v2:
- add mention to first patch that running patchtest for b4 prep --check
  is what we're eventually aiming for,
- add poky b4 wrapper script (it used to be in the patch series for
  poky, c.f. https://lore.kernel.org/poky/20250123-b4-support-v1-1-4841f52eccbb@cherry.de/T/#m95d6aa25cc42352416da477cf07d7b3cbd671231
- poky b4 wrapper script properly identifies patches with files modified
  in both OE-Core and other repos part of poky,
- poky b4 wrapper script pretty prints when there's more than one
  project modified by a script, instead of lazily printing a Python
  list,
- Link to v1: https://lore.kernel.org/r/20250117-b4-support-v1-1-fe74a5f50eb6@cherry.de

[PATCH v2 1/2] add basic b4 config file

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

b4[1] is a very nice tool for mail-based contribution. A config[2] file
exists to set up a few defaults. We can use it to set the Cc recipients
to always add, in our case the mailing list.

Because we do not have anything to check for now, disable needs-checking
so patches can be sent without running b4 prep --check. The
mid-term/long-term plan is to use patchtest locally.

Because we do not have any auto-to-cc support (and the implicit one
using scripts/get_maintainer.pl cannot work for us), also disable
needs-auto-to-cc so patches can be sent without running b4 prep
--auto-to-cc.

[PATCH v2 2/2] scripts: add b4-wrapper for poky

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

poky is a combo-layer containing BitBake, OpenEmbedded-Core and Yocto
Documentation source code into one big repo. It is not uncommon to have
people develop patches for either of those projects from a poky git
repo.
However, it is unlikely those patches are to be sent to the poky mailing
list as very few files contained in the poky git repo actually are
poky-specific. So we need a way to identify to which mailing list a
patch is destined to be sent.
Additionally, because the source code in openembedded-core is
merged/imported at the root of the git repo of poky, its .b4-config
introduced in the previous commit will be used if not overridden (which
will be done in a separate commit specific to the poky git repo). We
need to provide a different .b4-config in poky.

Therefore, this wrapper is used to identify automatically which mailing
list a patch series needs to be sent to (via b4 prep --auto-to-cc) and
does some additional checks (via b4 prep --check) such as making sure a
patch doesn't modify two different projects at the same time or that
multiple projects are modified by different patches in the same patch
series.

This wrapper script is meant to be used by poky's .b4-config. Ideally
the b4 prep --check part could be offloaded to `patchtest` once it
supports running on source different from OE-Core.

is there anything specific to poky in this script ? if not then it
should not use that in name, it will
make it confusing. In oe-core we do not refer to particular distros if
not needed.

Yes it is poky specific...

...git-repo poky specific, not poky distro specific. Do you have 
something better to suggest than this?

To be clear, we could "bury" this b4 helper script in some other
layer/place. I'm a bit reluctant to do it since I think there are
things in here which may help anyone else trying to split a repo into
multiple different submission locations, even just as a reference
implementation. As such I did suggest it go into core, even if that
looks slightly unusual.

As Quentin says, we're open to better ideas on naming but I do fairly
strongly believe hiding it somewhere else will just confuse things.

Cheers,

Richard

Messed up here and should be send-series-to instead according to our 
README.md. Same remark applies to all other b4 patches sent to YP/OE. 
I'll leave a few more days for feedback and send a new version to tackle 
that oversight.

Cheers,
Quentin

I merged the script and was about to look at the config files (which
need a little more work by tweaking combo-layer) but I'll hold off
given the issue. I think we're ready to merge them...
