"The page isn't redirecting properly" Error

This looks like a trac configuration error. The plugin's redirect redirects to the trac installation's login page. This type of error can be a result of incorrect Apache configuration and/or errors in trac.ini.

Please uninstall the plugin and click the login link in the navigation contributors. I suspect you will get the same result.

Err.. The above was me

This line seems to be the culprit for me:

req.redirect(self.env.href(req.href.login(), {'referer':req.abs_href(req.path_info)}))

"req.href.login()" returns "/trac/imasys/login" and the "self.env.href" function appends an additional "/trac/imasys" to the beginning of the url. I am not sure what configuration problem could be causing the error. I just changed the above line to:

req.redirect(self.env.href('login/', {'referer':req.abs_href(req.path_info)}))

... and it works for me. This might be accounting for my "misconfiguration" though.

Thoughts?

This sounds plausible. In order to determine possible configuration issues I will need some information. (Essentially, before I decide that this is indeed broken, I need to be certain that there isn't a configuration issue causing this.)

What I need are the sections of your httpd.conf responsible for serving trac (everything in the <Location (trac_location)/> ... </Location>) and the [project] and [trac] sections of your trac.ini.

I do not currently have anyplace to set up a test trac to debug this issue, so will be somewhat dependant on you and the reporter of #1777 to test :/

http.conf

<Location "/trac">
  SetHandler mod_python
  PythonHandler trac.web.modpython_frontend
  PythonOption TracEnvParentDir /var/lib/trac
  PythonOption TracUriRoot /trac

Trac config

Okay, I've managed to take a look at this. Please try the following:

While your workaround works, we don't really want to hardcode /login as it is possible that some patch, future update, or another plugin could change the login url from /login. I have verified that the above does work in trac installs on the root of the vhost (i.e. https://trac.example.org/)

The hard-code was my quick check. Your patch works fine.

Thanks,

Charlie

(In [2462]) Removed spurious self.env.href() that caused redirection issues on trac installation not at root of vhost. (fixes #1771)

In 0.11, this line should be:

- req.redirect(req.href.login(), {'referer':req.abs_href(req.path_info)}) 
+ req.redirect(req.href.login(referer = req.abs_href(req.path_info)))
