Develop migration discussion

[Geenz]

Hey everyone!

Creating a discussion thread to more or less help track where we're at with the great develop migration. I'd like us all to consider what changesets seem low risk to ship out over the coming months - pretty much anything is on the table at this point. Please use this thread to propose any specific changesets that would be good to pull in. PRs and commits all the same.

Just some quick notes on the maint-b merge into 2025.03.

We've decided to move forward with maint-b for 2025.03 - for the most part.

We determined that while what's in maint-b makes sense for us by and large, the Linux stuff just isn't really worth merging in from that release. archive/develop has a much more complete setup for that - and it likely makes much more sense to pursue that (or accept a more holistic change set) once we've gotten a bit more caught up here.

As for what's next - we will be evaluating maint-c's viability for 2025.04 or 2025.05. We also want to get a few other misc contributions in - we'll see what makes the cut for 2025.03, but most likely at this point we'll be kicking the can over to 2025.04 unless we identify some particularly low risk and easy to cherry pick stuff to get through the backlog. We're finding a couple here and there about every other day and will continue to pull those in as we get to them.

As for LINUX, I think the first goal should be to be able to build it on ubuntu-24.04.

• Replace sdl with sdl2-compat.
• Discontinue slvoice on Linux and switch completely to webrtc.

[AiraYumi]

I believe that the Linux changes have too many dependencies to be resolved by a simple cherry pick.

[Geenz]

RE: Linux - we will likely be salvaging that separately. There's a traceable lineage of commits there.

On the SDL front - it would likely be better to just move to SDL3. Compatibility shims I don't really see as valuable here - SDL3 is generally pretty solid.

WebRTC still needs more work as a whole. Hopefully I have news on where this stands in the priorities soon.

Thank you reply.

So should I discard the pull request I sent to the sdl2 repository?
Should I close ticket #3567?

[Geenz]

Yes. Realistically - we should not be supporting older APIs where possible, and should migrate up where we can. Continuing to support older APIs usually results in cruft that becomes problematic at some point down the line. In this case, given SDL3's API and the effort that would be required to support it, I don't think it's worth supporting SDL2 for much of a reason.

[AiraYumi]

I understand. I will abandon the pull request and close the ticket.
