I have just run into an ugly problem with TG 2.2.2 that you can
reproduce as follows:
* Quickstart a project
* Set in config/app_cfg.py:
base_config.sa_auth.authenticators = [('default', None)]
* Run paster setup-app
* Run nosestests
You get this error:
app = setup_auth(app, skip_authentication=skip_authentication,
**auth_args)
File "...\tg\configuration\auth.py", line 227, in setup_auth
return _AuthenticationForgerMiddleware(app, **who_args)
TypeError: __init__() got an unexpected keyword argument 'dbsession'
I think the problem is this:
When running the test, the app is configured with the same config object
multiple times. In the first run, in add_auth_middleware, the sqlauth
authenticator is created using create_default_authenticator(). In this
process, the "dbsession" parameter is removed from auth_args.
However, in the second run, the sqlauth authenticator is already setup
in the configuration, create_default_authenticator() will not be
executed, the "dbsession" parameter is not removed, and finally the
_AuthenticationForgerMiddleware will be called with that parameter which
it does not want to have.
The easiest way to fix this is to let _AuthenticationForgerMiddleware
ignore superfluous arguments. Any better ideas?
