"KeyError: password" when using trac-admin upgrade.

[verm]

While upgrading from 0.11 to 0.12 on FreeBSD 9.0-S, Python 2.6. I received this very unhelpful error message while running trac-admin upgrade

KeyError: password

Eventually after some trial and error I found that supplying --no-backup made the error go away.

I'm guessing this an actual bug as the l/p information was correct otherwise --no-backup would not have worked. (I'm assuming 'password' here is the actual login pw.)

The only viable alternative is letting the user know it failed during the backup step and to use —no-backup. With a nice (obvious) warning to backup their database manually.

Which database backend are you using? Could you please look in your log if you can get the full traceback for the error?

[verm]

MySQL — I can't believe I forgot to mention that.

The log is empty, do I need logging enabled for the frontend to catch an error from the console binary? If so that doesn't make much sense.

Thanks for the additional info. I assume you don't need a password for Trac to access the database, so your DB URL is something like (i.e. without a password):

mysql://user@host/database

Yes, in that case, we throw a KeyError. Unfortunate. I'll fix that.

Fixed in [9942].

Actually, my db string is:

mysql://trac:tracuser@localhost/trac

I'll try your update and see if I can reproduce the problem afterward.
