Ensure session store complete before redirect

[eddiesholl]

I'm converting session storage for an app from MemoryStore to connect-couchdb. The login page is now flaky, and I think it is because the new session storage is slow enough that it has highlighted a race.

It looks like the successful login is redirecting (in our case successReturnToOrRedirect: '/'), and the 'session get' for / occurs before the 'session set' has written to the database. I've used some extra logging through the connect-couchdb and passport code to confirm this.

Is there a way to make sure req.session.save is called and completes before res.redirect gets called on success? The optional callback you can pass into authenticate() replaces all builtin handling, I was hoping for a solution where it can be augmented.

Any thoughts on this?

Cheers,

Eddie

Did anyone find a solution/workaround for this? I find this is very troublesome. The same issue exists in connect-ensure-login (they are probably written by the same person after all), but that one is much easier to fix (jaredhanson/connect-ensure-login#28). This one seems very complicated though.
