I've run into this behavior for a while, for several CentOS
versions, depending upon the application.
there are also (at least in X) two ways to cut and paste:
1. select with mouse then paste with middle-click.
2. select with mouse, right-click "select", paste the right-click "paste".
My understanding is that oneuses X facilities and the other is
part of the desktop.
I would surmise that Weston could be different.
We should distinguish two selection methods PRIMARY and CLIPBOARD [1].
The former is the traditional way (X11) also usable via middle-click.
The latter is the cut/paste via shortcuts or context menu of the desktop
environment.
Both work on different layers but that is not my question.
Using the CLIPBOARD layer I wonder why the cuted data disappears
(or gets deleted) when the source application gets quit.
This behavior is situated in Wayland. gedit and gnome-terminal
uses the Wayland protocol.
Scenarios:
WORKS: gedit (copy) -> terminal (paste) -> DATA
DOESNT: gedit (copy)(quit) -> terminal (paste) -> NODATA
or vice versa (application).
Another applications using the Wayland protocol:
$ env MOZ_ENABLE_WAYLAND=1 firefox
WORKS: firefox (copy) -> terminal (paste) -> DATA
DOESNT: firefox (copy)(quit) -> terminal (paste) -> NODATA
but when using the X11 protocol (under Wayland):
$ firefox
WORKS: firefox (copy) -> terminal (paste) -> DATA
WORKS: firefox (copy)(quit) -> terminal (paste) -> DATA
or
$ GDK_BACKEND=x11 gedit
WORKS: gedit (copy) -> terminal (paste) -> DATA
WORKS: gedit (copy)(quit) -> terminal (paste) -> DATA
So, is this a Wayland bug or a "security feature" of Wayland?
