tracd is started with:

"repos" is not the subversion repository of course, but the trac environment.

Notes / ideas:

• Tried to make db_name and last directory in "repos" the same, as prescribed by various pages. (Is this understood correctly?)
• The project name given when doing initenv, which appears in headers of HTML pages - does that matter? (tried redoing it with same name, does not seem to matter…)
• Just noticed, the "realm" is not a complete or correct hostname if that matters, just "trac"

/var/www/trac/htdigest contains only one line:

gan:trac:44ab342...<the hashed password>...

with these permissions (nothing odd I guess, probably shouldn't be world readable though…)

To clarify, the error trace appears anytime I try clicking "Login"

Looks like a strange python bug. Hope you gurus will figure it out.

rfc822.py contains

   # Access as a dictionary (only finds *last* header of each type):
   def __getitem__(self, name):
       """Get a specific header, as from a dictionary."""
       return self.dict[name.lower()]

If I understand the error, then 'Authorization' gets turned into an int when entering the local __getitem__ ???

Anyway I wrote a workaround avoiding the __getitem__ implementation in headers by accessing the internal dictionary directly, (not very nice) using a lower-cased key.

i.e.:

if not 'Authorization' in req.headers

changed to

if not 'authorization' in req.headers.dict

and so on.

Works for me! (Yay!) It seems a bit fragile to access the member "dict" directly however so I leave it up to you to use the ugly patch, or figure out the problem.

I did not affect the other places where other dictionary-like accesses are made. Please investigate them too. For example:

        if self.headers.has_key('Cookie'):
            self.incookie.load(self.headers['Cookie'])

    def get_header(self, name):
        return self.headers.get(name)

By the way I'm using python 2.2 ! Could be a bug only in that version perhaps…

rough patch (workaround)

Wow, 0.7.1 is old. I think this was probably fixed long ago in the changes that have happened since then.
