Description Gary van der Merwe 2015-04-09 12:40:34 UTC

This is the same as bug #55183, but for weston as opposed to libwayland.

Projects that wish to work with weston specific protocols need to copy have copies of the protocol xml files. e.g. maynard has keeps a copy of desktop-shell.xml. (https://github.com/raspberrypi/maynard/blob/master/protocol/desktop-shell.xml)

It would be great if the appropriate protocol xml files from weston were installed and discoverable like they are with libwayland.

I'm going to claim that the establishment of wayland-protocols resolves this bug, although I'll admit it didn't fix desktop-shell.xml specifically.

When that package was made, all protocols that were felt to be of general utility were moved there.  A few protocols, including the desktop-shell.xml protocol requested in this bug report, were left in weston, either because they were considered too weston-specific, or because they were not felt to be something the Wayland developers wished to see adopted externally.

The desktop-shell.xml protocol was renamed weston-desktop-shell.xml to indicate its specificity to weston.  While there is some functionality included in it that isn't (yet) in xdg-shell.xml, I believe the feeling is that we'd rather see necessary protocol functionality added to xdg-shell.xml or separate protocols in wayland-protocols than to have weston-desktop-shell.xml be more broadly shared.

So, I would suggest if there are bits of desktop-shell.xml that projects like Maynard want, please file proposals to expose those specific functions.

Comment 2 Pekka Paalanen 2016-03-18 08:51:33 UTC

Just a minor correction: weston-desktop-shell.xml has nothing to do with xdg-shell.xml. Weston-desktop-shell.xml is the private protocol used between the DE components specific to Weston, while xdg-shell.xml is a public protocol for all apps.

Proposals to generalize or publish things related to weston-desktop-shell.xml should be new protocol extensions of their own. That stuff does not belong in xdg-shell.xml.

Of course, nothing prevents promoting weston-desktop-shell.xml into wayland-protocols, *if* it is deemed necessary. But while libweston is still seeking form, I'd advice to wait.
