Authentication failures with 0.7-pre

[jon@…]

When attempting to view any page served by trac.cgi I am given the following message:

Trac detected an internal error:

0

With this backtrace:

Traceback (most recent call last):
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 424, in cgi_start
    real_cgi_start()
  File "/usr/lib/python2.1/site-packages/trac/core.py", line 388, in real_cgi_start
    authenticator = auth.Authenticator(database, req)

KeyError: 0

This looks like you have some malformed cookie that the Cookie-module chokes on.

Can you try to remove all cookies (for that site) from the browser and see if that helps?

[jon@…]

There are no cookies set for the subdomain trac is running under, or the parent domain.

Ok, I know what it is now. Python2.1 doesn't like stuff like this:

if 'key' in cookie:

This should work instead:

if cookie.has_key('key'):

I'll commit a fix for this later today. Thanks for your report!

[jonas]

Fixed in [419].
