Status update, December 2023

Hi all!

This month we’ve finally released wlroots 0.17.0! It’s been a long time since the previous release (1 year), we’ll try to ship future releases a bit more frequently. We’re preparing 0.17.1 with a collection of bugfixes, it should be ready soon.

I’ve been working on wlr_surface_synced, a new wlroots abstraction to allow surface commits coming from clients to be delayed. This is required to avoid stalling the whole compositor if a client GPU work is slow and to implement explicit synchronization. I’ve also been working on a commit-queue-v1 implementation for wlroots and gamescope, which will allow us to get rid of a CPU wait in Mesa. And I’ve put some finishing touches on Rose’s frame scheduler patches. Last, I’ve merged André Almeida’s kernel patches for atomic async page-flips, making it so modern compositors can enable tearing page-flips without having to go through the legacy KMS uAPI.

I’ve added OAuth refresh tokens to meta.sr.ht. Having to renew OAuth tokens every year on my clients is annoying, with refresh tokens that’s a thing of the past! I’ve already updated hottub (CI bridge for GitHub) to leverage this, and I’d like to also implement this in hut (CLI tool) and yojo (CI bridge for Codeberg). Note that since meta.sr.ht has only now started returning refresh tokens on login, users will need to re-login one last time so that the OAuth clients can grab the refresh token.

The NPotM is a bit peculiar: I haven’t actually started working on it this month, and it’s not in a usable state yet. It’s go-sqlgen, a Go code generator which takes SQL as input. The goal is to store SQL queries in a separate file, to make them safer (type checking for the arguments) and faster (prepared statements). It’s somewhat similar to sqlc except it aims at being simpler and database-agnostic. There’s still much to do: I’d like to add support for named parameters, check that the number of parameters in the query matches the number of procedure arguments, and make it easy to write migrations. I’m not yet sure go-sqlgen is worth the trouble: being database-agnostic limits its abilities, perhaps too much.

Then comes the usual mix of random smaller updates. I’ve released soju 0.7.0 and goguma 0.6.0 with a few new features and bugfixes. pyonji now understands the b4 config file, so it’s possible to add this file to your project to preconfigure pyonji with a mailing list (example). delthas has implemented account data import in hut, so it’s now easy to migrate accounts between sr.ht instances, or projects between accounts. go-scfg now supports decoding a configuration file directly into a Go struct, making it unnecessary to hand-roll parsing code (example).

I’ll be giving a FOSDEM talk about quirks and gotchas of the IMAP protocol this year. I’ll be happy to say hi if any of you are coming as well. That’s all I have for this month, see you in January!
