TypeError when calling /openidverify (/openidlogin before) (0.11.1)

[ahmann@…]

I have successfully installed trac 0.11.1 with basic http auth.

Now i think using openid would be the better option, so i instaled this plugin. Everything looks fine, except when i click on the openidlogin link. See traceback of trac.log below:

Python 2.4 is installed. python_openid-2.1.1 is installed. ​http://hg.sandbox.lt/authopenid-plugin/archive/v0.1.2.tar.gz is installed.

Kind regards ! Sashman

It looks like you have set default_openid value. If you don't know what's directed identity is don't use it. Could you please give your configuration if that does not help?

[Dalius]

I'm pretty sure that it is configuration issue.

[ahmann@…]

(Reopened because somehow related)

Hi there,

It looks like it indeed was a configuration matter. However, i am really missing all configuration options and what they do.

Right now, i followed your lead and removed the directed identity. Now the /openidlogin page doesnt except, but the /openidverify does.

Here is the traceback from debug:

TypeError: len() of unsized object

I am simply entering valid openid adresses, with ​http:// in front and without. It is always triggering this error.

When i entered nonsense, like "dhfjsdfjl", it says at least "Error in discovery: Error fetching XRDS document: <urlopen error (-2, 'Name or service not known')>".

I know the error is thrown in the python-openid package. However, i think this must be due to the configuration again?

My config looks nearly like your example:

[openid]
#default_openid = http://openid.ee
sreg_required = false
whatis = http://openid.net/what/
absolute_trust_root = true
strip_protocol = false
strip_trailing_slash = false
timeout = false

I would be happy to get this thing going, finally.

[Dalius]

OK. I guess x value in that case is None or something similar. We should find out somehow how this situation happens. The only unusual thing I see is x86_64. Are you using 64 bit OS?

Since I can't reproduce this bug I will need your help. The best you could do is to add more logging. Can you handle that?

[anonymous]

indeed it is a 64bit system (2.6.18-5-amd64 #1 SMP). How can i enable more logging? The trac conf is already outputting debug level logging.

Can you point me in the right direction?

[Dalius]

You should add entries in format:

???.debug('something %s' % (repr(x),))

Search for similar entries and just add them to python files. E.g. this file: build/bdist.linux-x86_64/egg/openid/yadis/etxrd.py

Those files should be where you have installed python-openid library.

It really looks like openid library issue.

[Dalius]

Or simply add strings like this one:

print x

[anonymous]

i can unpack the source from python-openid-2.1.1, then modify openid/yadis/etxrd.py and then easy_install that one.

But where is the print x output going to?

for example, i added "print e" in the function:

def prioSort(elements):
    """Sort a list of elements that have priority attributes"""
    # Randomize the services before sorting so that equal priority
    # elements are load-balanced.
    random.shuffle(elements)

    prio_elems = [(getPriority(e), e) for e in elements]
    '''print e'''
    prio_elems.sort()
    sorted_elems = [s for (_, s) in prio_elems]
    return sorted_elems

But i dont know where this output is going to (as i said, i have never done any python)

[anonymous]

print e = print e (bold formatting not applied to a code block)

[Dalius]

You can actually do it this way. Unpack and run command: python setup.py develop (where setup.py file is). This way you can modify *.py files in place. You will only need to restart trac server.

print issue. You must run tracd deamon (no apache or other web server) because print outputs to standard output: tracd -p 8080 /path/to/trac

[Dalius]

BTW. What DB are you using? PosgresSql is not tested on my side. SQLite and MySql are tested.

[anonymous]

In the directory where the setup.py is, i entered "python setup.py develop"

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]

or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help

error: invalid command 'develop'

This doesnt seem to work.

I also started tracd standalone, but it didnt output anything except all the files that are being processed by GET or POST.

sqlite is used. I also made sure python sqlite2 interface is installed.

[Dalius]

OK. That might be possible that openid library is not written properly.

About tracd. Make sure you have proper entries in trac.ini for logging:

[logging] log_file = trac.log log_level = DEBUG log_type = stderr

print statement should work unless there is something done what eats all output to standard output. That's OK that you see GET and POST statement but I think you should be able to see output from print statement. You can make it more visible this way:

print '*'*80 # print 80 asterisks print ... print '*'*80

[anonymous]

ok. I have put print '*'*80 into it, to see if there is any ouput at all, which is not. (stderr is showing the debug now).

Right now i am out of options here, and i feel the pain explaining simple python, especially when it is a problem with python-openid, and not your plugin.

How do you think is the best way to further proceed?

[Dalius]

You could try newer python openid library. Maybe that will work?

[Dalius]

BTW you can create ticket in python openid library ​http://trac.openidenabled.com/trac/report/1
