Changing username during an active session causes the user to get stuck in 'offline' mode

[Maddieman]

This came up while we were testing changing usernames.

The issue here is that the user gets stuck in the (Offline) state, and can't log out or re-authenticate. The API returns Authentication Failed, but the client treats the error as if the user is offline and starts caching scrobbles.

Expected behaviour: User is automatically logged out and forced to reauthenticate.

Thanks for the files. I'll pick this up today, and make sure the application is fixed to behave the way it should!

@Maddieman Having loaded the settings file, and started the application - I'm getting an Invalid Session key and the application is throwing me back to the authentication loop.

I can't find anywhere on the website to change my username (only display name), so I can't test if this is an issue that occurs whilst the application is running.

Can someone point me at how to change my username and / or elevate my permissions so that I can do so? (A general google search suggests the changing of username is not supported)

Hi @VorTechS, I think Ben is away for the week, he asked me to file this one as we stumbled on this doing something else. I don't know how critical it is. Changing username is not a feature we officially support, but something we might be adding in the future, that's why we were testing against it to see how the client behaved. We can set up another test when he gets back, if needed.

We set this up by opening the application, authenticating, starting a playlist, and then changed the username after a few tracks had played.

It's weird though, on my computer it still treats the session as valid, even if I restart the application / my laptop (or at least, it doesn't prompt me to reauthenticate). Did I miss a file?

When I start it up again, the logging file reports:
