Oops… Trac detected an internal error:

could you pls shed some light on:

• your client pc:
  • what did you try to do
  • what operating system did you use
  • what browser with what cookie settings?
• the server:
  • which url
  • which trac version

[franz.x.maier@…]

I tried to retrieve the following url:

​http://www.boxbackup.org/trac/wiki

I use Windows XP with all actual fixes and used Firefox and IE - same results! I even couldn't go to your homepage as indicated in the description (using the link) and report the error - also got this error! Strange thing: it now works in Linux (Suse 10.3) with Firefox - everything ok there! Cookie settings: defaults in all systems and browsers.

Above URL works fine for me on Mac with Firefox. Sounds like a browser configuration problem to me.

This (the "Session ID is not set" error, I do not know about the rest) triggered exactly when work admins installed a crappy anti spyware thingy on the WinXP box. Seems that the thing regularly cleans out cookies in some way. I think this is related to this error.

Please note that I'm anonymous, req.incookie.has_key(COOKIE_KEY) seems True.

The trac cookie is empty (empty string contents) and if I delete it, the error does not trigger anymore for one day.

This sounds very likely indeed. Not an InstallationIssue, but same conclusion. Please fix your client environment.

[alexandre.rossi@…]

My opinion is that Trac should not fail for anonymous users if :

• they come back to the website after more than one day
• something's messing up cookies on the client side.

I think that when users are anonymous and cookie information is not good, it should simply be discarded.

Yes, that does make sense. It will "hide" the real problem from the user, though, so their settings will get lost every time, but maybe that's acceptable.

Refocusing.
