The Wakefield committers may hold off-line discussions from time-to-time. Since these meetings are just for the committers and invited wayland experts, summary minutes will be recorded here as time permits
Online Zoom Meeting 9am PDT 7th April 2022
Attendees: Alexey Ushakov, Olivier Fourdan, Niels de Graef, Jonas Adhal, Sergey Bylokohov,
Alexander Zvegintsev, Zhengyu Gu, Phil Race, Kevin Rushforth, Victor Dyakov
Working on pure wayland, can show AWT and Swing frames with sime simple rendering in paintComponent
Nikita working on font rendering. Will push to branch on openJDK when ready.
3rd thing is AWT robot - Maxim is providing custom extension to Weston instance to get it working.
Alexander : does extension cover screen shot + key press : yes - works even for multimon ...
this is useful for testing but not for production
Sergey : how difficult to install this extension ?
Alexander: Reported a bug about XOR rendering but it could be a driver bug ?
Screencast still not usable because have to configure it manually every time you start a session
So weston extension looks more promising (for testing)
Need some scripting support
Jonas: maybe not running in a sandbox or something - should be possible to make it remember
what you selected in a dialog.
Maybe be missing a way for portal to associate request with application ID
Screencasting portal configures a token that should make it possible
Screenshot portal doesn't remember that _yet_ though
You can follow this issue for the latter: https://github.com/flatpak/xdg-desktop-portal/issues/649
Niels De Graef : Note that a wl extension protocol that disables security features like that probably won't fly in any compositor
( Jonas & Niels?) : AI: Are there any particualr JDK requirements around input methods - there is a slow moving project
to update in update flawed gtk3 4 protocol .. Phil will have to get back on that after asking around.
Online Zoom Meeting 9am PST 10th Mar 2022
Attendees : Maxim, Olivier Jonas, Alexey, Niels De Graef, Phil, Alexander, Kevin, Victor
Alexander : has been doing testing of current JDK on Oracle Linux 8.5
This uses gnome 3.32 - old gnome shell - so not getting recent fixes
So just a point of reference
Getting some new failures (tests that passed before ) on Ubuntu 21.04 and 21.10 - likely this is due to updated OpenGL drivers
Some JDK screen shot tests failing but need to implement something so not an unexpected problem
Olivier : update on Drag and Drop - the upstream fixes have landed in gnome 42 and 40
X.org not likely to be removed any time soon by any distro as most are oonly just switching to
wayland as the default. So we have time. Perhaps some cutting edge distro will be first but not soon.
Alexey : Up date on pure wayland work - trying to support just one AWT button but needed to bring in
whole AWT hierarchy - meaning a lot of the equivalent of the Xawt toolkit.
Kind of working but faced with problem of placing location of windows on desktop
can only provide coords for popup surfaces We've talked before about this being part of the design philosophy of wayland
Surely this is needed even for applications that try to place their windows relative to each other ?
Jonas: this has come up in discussions about whether it makes sense ..
GIMP might need this ? Well maybe not GIMP because it is moving away from multiple images but
some medical applications have a need .. but it may be more like session management
1st time launch rearrange your windows. then the extension protocol can be used to save this.
[ Editor : I'm not sure if this would work for JDK needs and how would we expose that protocol to apps ?
It can't just be "java" as that's the platform not the application.]
Alexey is focused on the rendering side. Dmitry Batrak will be looking at event handling.
And Maxim is thinking about Robot - prototyping some new approach to automated testing ... run tests in a weston instance on top of X11 ?
Only useful for testing. Using a custom protocol extension.
Peter Hutterer working on libei and has made a 0.2 release Jonas working on it too.
Concentrating on 2 parts : capturing events and other is sending input events
feature where input captured from compositor - like Synergy which forked into Barrier and then again
That project is to share input devices across multiple computers mouse events go to the other computer when the mouse
goes off edge of screen and emulate events on other computer
API mostly written down but not yet stable.
Peter Hutterer made a 0.2 pre-release.
Blog here :
In the world of sandboxing and flatpak not guaranteed that they have same version of a library.
So not going to make it into any distro even as a pre-release until API and wire format are stable.
