This can lead to all kinds of funny situations that we don't want. IMO we should require that shutdownBackend() is called explicitly before loading a different backend, enforcing that QPluginLoader::unload() is called first, m_backend is cleared etc. Same goes with changing the KSCREEN_BACKEND_ARGS - while calling init() to re-init works for the simple Fake backend, it might not be enough for more complex backends. Basically the intended behaviour is that you call get(InProcess)Backend() (or something like that), and you fall back to parsing the env variables and calling loadBackendInProcess() if getBackend() returned null pointer. Or you can just move the env parsing to loadBackendInProcess() when loading a new plugin, always returning the cached backend unless it's null, then loading based on current env variables. src/configoperation_p.h (line 43) <https://git.reviewboard.kde.org/r/126101/#comment60687> Maybe we don't even need to store it? Looking at the implementation in both Operations, it might just fine if loadBackend() returned the backend pointer... - Daniel Vrátil On Nov. 18, 2015, 3:36 a.m., Sebastian Kügler wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
