A Look At The Wayland/Weston Development Stats For 2018

WAYLAND --
This year was interesting for Wayland with the compositor support continuing to mature for both GNOME Shell and KDE Plasma, the smaller but very interesting i3-inspired Sway nearing its 1.0 release, NVIDIA working on EGLStreams support for the KWin compositor, and other advancements. But at the same time the year was unfortunate in that Samsung let go of their Wayland developers as part of their OSG restructuring, which had contributed heavily to the upstream project. Here's a look at Wayland/Weston 2018 by the numbers.

Wayland proper itself didn't see too much activity with the core Wayland itself being quite mature and the developers decided this year that it won't be tied to new Weston releases on their timed release cadence.


Wayland's Git repository saw just 70 commits so far this year compared to 78 the year prior and 150+ in the prior years going back to 2009. This year saw 792 new lines of code and 357 removed, a low point in the history of the project.

The most prolific Wayland contributor this year was Derek Foreman (Samsung) followed by Daniel Stone, Emil Velikov, Pekka Paalanen, Simon Ser, and Michal Srb. More of the Wayland data can be found via this GitStats output.

The Weston reference compositor is where more of the "magic" happens these days, besides all of the other desktop Wayland compositor implementations. But even on a commit basis, there were just 283 commits to Weston this year compared to 437 last year, and 600+ the prior years going back to 2010 when there were 248. There was just 9.6k lines of code added and 3.6k removed, the lowest point since 2009.

The most prolific Weston contributors this year were Pekka Paalanen of Collabora followed by Daniel Stone, Emre Ucan, Derek Foreman, Marius Vlad, and Alexandros Frantzis. Weston itself is up to 153,343 lines of code. More details on Weston's Git activity via this data.
