I've let it sit idle, with no connections whatsoever, for 5 minutes and the release method of plugin was never called. I can see the DLL loaded in list of handles kept by firebird.exe, if I'm not attaching debugger.
It's not even called when I do shutdown of server (on Windows from the tray icon), but that might be intentional. The first addRef I call from factory - as in docs. Then the other call comes in from Firebird::IExternalEngineBaseImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::IPluginBaseImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IReferenceCountedImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IVersionedImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IExternalEngine> > > > > > >::cloopaddRefDispatcher(Firebird::IReferenceCounted* self). After that - even before any execution happens - release is called from Firebird::IExternalEngineBaseImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::IPluginBaseImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IReferenceCountedImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IVersionedImpl<FbNetExternalEnginePlugin::Plugin,Firebird::ThrowStatusWrapper,Firebird::Inherit<Firebird::IExternalEngine> > > > > > >::cloopreleaseDispatcher(Firebird::IReferenceCounted* self). After that the counter stays on 1 and I never see the release and hence the cleanup etc. What can I check now? -- Mgr.
