[PATCH 0/2] drop Debian 11 from supported distros

[PATCH 0/2] drop Debian 11 from supported distros

[Quentin Schulz]

Ross recently sent a patch to remove Debian 11 from supported distros in
poky[1].

Let's do the same for the docs.

While at it, I also removed some comments in the build-docs-container
for distros we currently couldn't support because of missing packages
(or other issues) that we anyway don't support anymore.

[PATCH 2/2] remove Debian 11 Bullseye from supported distros

[Quentin Schulz]

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

Mirrors a change made to poky recently justified by the fact that
Bullseye has ended normal support and enters LTS support which is
best-effort and only by the LTS community.

Re: [PATCH 0/2] drop Debian 11 from supported distros

[Quentin Schulz]

Reading a bit more the docs, I'm wondering if we shouldn't add Debian 11 
to the list of "distros we supported but we don't anymore" for older 
releases in the docs, e.g. kirkstone, scarthgap and walnascar if we 
really are dropping Debian 11 from the builders?

Yes, basically if the Autobuilder workers for debian-11 are turned off
completely (not even run for stable branch), we can move it below the

However if we still run workers for stable branches, we can move it under the

Let's wait until the patch from Ross gets merged on Poky and see what is done
with the workers.

I was meant to speak to you about this, as RP had concerns that the scripts that compare the AB setup with the docs won’t like this.

We want to keep debian-11 around for walnascar and earlier, but not build on it for master/whinlatter onwards.  I know we can do this for the AB, but is the script that keeps the docs in sync with the AB happy with this too?

For master, the script has a logic to detect when a worker is configured on the
AB but not listed in SANITY_TESTED_DISTROS, to avoid forgetting to update the
file. It looks in all_workers in config.py[1]. So I think it will be an issue.

But I wonder how are you going to configure the worker to run _only_ on
walnascar and earlier? Remove it from workers_debian[2] in config.py and leave
it in workers_prev_release[3]? Does that make the AB automatically pick a
debian11 builder for stable branches?

We could maybe solve this by adding a "master" entry to workers_prev_releases
(we could rename that variable too), and have master run on all the available
workers in all_workers minus the one we want to drop.

To illustrate, something like:

workers_prev_releases = {
    "master": all_workers.remove("debian11*"),
    "walnascar" : ("alma8", "alma9", "debian11", "debian12", "fedora39", "fedora40", "fedora41", "opensuse155", "opensuse156", "rocky8", "rocky9", "stream9", "ubuntu2004","ubuntu2204", "ubuntu2304", "ubuntu2404", "ubuntu2410", "perf-"),
    ...
}

And then the script can be adapted to read from this dict no matter if it's
master or a stable branch.
