launchpadlib scripts break when run under python 2.6

  File "/usr/lib/python2.6/httplib.py", line 699, in send
    self.connect()
  File "build/bdist.linux-i686/egg/httplib2/__init__.py", line 736, in connect

  File "<string>", line 1, in settimeout
TypeError: a float is required

I don't see this issue, and the appearance of an egg there is a difference
that is immediately apparent. Do you know where this is getting
picked up from, and does avoiding it make the problem go away?

Thanks,

James

I just remembered bug 336067, could you check if the egg is too old
to contain that fix?

Thanks,

James

This bug does not affect the python-launchpadlib in Ubuntu, but in the Launchpad specific PPA that provides legacy support for python 2.4. I reverted back to the official python-launchpadlib and everything works.

I'm confirming this bug, since launchpadlib isn't working under python 2.6 when installing using 'python2.6 setup.py install'.

Hi,

Could you include the output of

  apt-cache policy python-httplib2

and

  python -c 'import httplib2; print httplib2.__path__'

please.

Thanks,

James

I haven't been able to test this, but a possible workaround is to pass in timeout=20.0 when creating the Launchpad object. Try this and see if it works.

That's odd.

Was this installed by setuptools at some point?

It seems that a new release of httplib2 has not been made with
the python2.6 fix, so any setup.py install will lead to this
error.

If you remove the egg and use the packaged version then you
won't have this issue.

Thanks,

James

No, that workaround doesn't seem to work.

Yes, it was.

Right. It's still an issue that installing via setuptools doesn't work.
The reason I installed via setuptools was that the latest launchpadlib
bzr revision wasn't available as a package.

I don't think the real issue is in launchpadlib, but in the upstream httplib2. What I did to fix the bug is to install the packaged version of httplib2, and that's it. It worked fine after that, and I'm running Tarmac on Jaunty now.

I'd say it is an issue with launchpadlib, since it installs the broken
version of httplib2.

I was really confused by this issue so I asked Gary to do some research and he came up with the following.

1. The problem is a real problem in stock httplib2 0.4.0.
2. The httplib2 that comes with Jaunty is patched to avoid or fix the bug.
3. The Launchpad PPA includes an httplib2 that has the bug.

So if you use Jaunty as a normal user, you shouldn't have a problem. If you use Jaunty and you're also a Launchpad developer, you'll have the problem (because the PPA version has the bug). If you check out the source from Launchpad, you'll have the problem (because the PyPi version has the bug).

See https://bugs.edge.launchpad.net/ubuntu/+source/python-httplib2/+bug/336067 and the related httplib2 bug linked there.
