Title:
mir_connection_create_surface callback is sometimes called twice on
error
Status in Mir:
Fix Released
Status in mir package in Ubuntu:
Fix Released
Bug description:
I've just run into some fun behaviour. In mir_surface.cpp, in the
surface constructor, if:
server.create_surface(0, &message, &surface, gp::NewCallback(this,
&MirSurface::created, callback, context));
throws (such as if the RPC mechanism detects a connection break) then
the created callback is called on the partially constructed MirSurface
that's just about to be destructed. mir_connection_create_surface
catches this exception and then calls the callback *again*, with an
newly constructed error MirSurface.
This is likely to confuse API users :)
