Status update, June 2024

Hi all!

This status update will be shorter than usual because I had a lot less free time for my open-source projects than usual this month. Indeed, I recently joined SNCF Réseau (the company responsible for the French railway infrastructure) to work on OSRD, an open-source tool to design and operate railway networks. The project’s immediate goal is to fit new freight trains in an existing timetable a few days in advance, but the longer term scope is much larger. Working partly on-site in a big team is quite the change of pace but I like it so far!

I’ve released a lot of new versions this month! The big one is Wayland 1.23.0 which adds a mechanism to set the size of the internal connection buffer, an enum-header mode for wayland-scanner to generate a header with only enums, auto-generated enum validator functions for compositors, a new deprecated-since attribute to mark parts of protocols as deprecated, and a few other niceties. libliftoff 0.5.0 prioritizes layers that are frequently updated, adds performance optimizations (a fast path when the intersection of layers doesn’t change, a fast path for standard KMS properties, an early return to avoid needlessly trying potential solutions) and a timeout to avoid stalling the compositor for too long. soju 0.8.0 adds a new file upload IRC extension, adds support for Unix domain sockets for HTTP and WebSocket listeners and better spreads the load on multiple upstream servers on large deployments. kanshi 1.7.0 adds output defaults and aliases. Phew, that was a mouthful!

In other Wayland news, the xdg-toplevel-icon protocol got merged after a long and difficult process. I really hope we can improve the contribution experience for future proposals. We realized that the governance document was missing the review requirements, so I fixed that along the way. The wlroots linux-drm-syncobj-v1 implementation has been merged (it’s been used by gamescope for a few months - note that this does not include the wlroots renderer, backend and scene-graph changes). Multiple wlroots versions can now be installed side-by-side thanks to Violet Purcell. Sway has gained a new color_profile output command to apply an ICC profile to an output thanks to M. Stoeckl. A high-level API for colorimetry has been added in libdisplay-info thanks to Pekka Paalanen, and support for HDMI audio data blocks has been implemented by Sebastian Wick.

Let’s switch gears and talk about IRC updates. I’ve submitted an IRCv3 proposal to fix a few ISUPPORT deficiencies - it will need a lot more feedback and implementations before it can be accepted. I’ve continued debugging Goguma’s duplicate message bug and I’m pleased to announce that I’ve almost completely fixed it (I still experience it very rarely somehow…). delthas has added support for adaptive color schemes (Goguma now uses your preferred accent color if any). I’ve performed some more boring maintenance tasks, for instance adding support for newer Android Gradle Plugin version to webcrypto.dart, one of Goguma’s dependencies.

One last update to wrap up this post: Zhi Qu has added support for the ID extension to go-imap, which is sadly required to connect to some servers. That’s all for now, see you next month!
