Brokenness in ubuntu oneiric

[Brad Hall]

I'm getting different behavior with the imports between natty (python 2.7.1) and oneiric (2.7.2):

On natty:

$ python
Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import tools.source_environment
>>> import quantum
>>> print quantum.__path__
['/home/bhall/src/git/quantum-trunk/plugins/openvswitch-plugin/lib/quantum',
'/home/bhall/src/git/quantum-trunk/plugins/sample-plugin/lib/quantum',
'/home/bhall/src/git/quantum-trunk/plugins/cisco-plugin/lib/quantum',
'/home/bhall/src/git/quantum-trunk/client/lib/quantum',
'/home/bhall/src/git/quantum-trunk/server/lib/quantum',
'/home/bhall/src/git/quantum-trunk/common/lib/quantum']
>>> import quantum.plugins
>>> print quantum.plugins.__path__
['/home/bhall/src/git/quantum-trunk/plugins/openvswitch-plugin/lib/quantum/plugins',
'/home/bhall/src/git/quantum-trunk/plugins/sample-plugin/lib/quantum/plugins',
'/home/bhall/src/git/quantum-trunk/plugins/cisco-plugin/lib/quantum/plugins']
>>>

On oneiric:

$ python
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import tools.source_environment
>>> import quantum
>>> print quantum.__path__
['/home/bhall/src/git/quantum-trunk/plugins/cisco-plugin/lib/quantum', '/home/bhall/src/git/quantum-trunk/plugins/sample-plugin/lib/quantum', '/home/bhall/src/git/quantum-trunk/plugins/openvswitch-plugin/lib/quantum', '/home/bhall/src/git/quantum-trunk/client/lib/quantum', '/home/bhall/src/git/quantum-trunk/server/lib/quantum', '/home/bhall/src/git/quantum-trunk/common/lib/quantum']
>>> import quantum.plugins
>>> print quantum.plugins.__path__
['/home/bhall/src/git/quantum-trunk/plugins/cisco-plugin/lib/quantum/plugins']
>>>

The trunk is at the same point in both trees (updated as of 5 minutes ago).

With the current behavior on oneiric we're unable to run all of the tests or start the server from the source tree. I'm not sure why but it seems the module overloading that we're doing (multiple quantum.plugins directories, etc) is defeating us.

[Salvatore Orlando (salvatore-orlando)]

With a 'standard' run_tests execution, do you find out just 98 tests get executed?
I had a similar issue, as I found out that quantum.tests.__path__ did not contain all the tests directories.

It seems the distribute package does the job of concatenating the different 'tests' directories coming from different paths into __path__ variables, but this does not appear to be working with the version of distribute I had in my oneiric distro (0.6.16).

I think this version of distribute come from python-setuptools (which we typically install with apt-get as that's the package where we find easy_install). Anyway I upgraded distribute to 0.6.24 using easy_install; after that the __path__ variable had the correct value.

That said, it still puzzles me why the __path__ variable gets configured correctly in natty, which I think uses distribute 0.6.15.

Hmm.. you're right. I installed 0.6.24 and it works fine now.. thanks!

[Brad Hall (bgh)]

Guess this means we should update pip-requires to use that version if available.

    Fix for bug 888811

    Use version 0.6.24 of python-distribute which allows us to find all of the
    test directories on ubuntu oneiric.
