Hi all,

The couchDB issue Michael mentioned in independent and had to do with a
system update on my system; so ignore it.

I just ran the test on my ubuntu system running on vmware ( where I am also
running Rabbit 2.7.1 and Couchdb 111 ) and it passed:

bin/nosetests -v -a INT ion/services/dm/distribution/test/test_pubsub.py -s

----------------------------------------------------------------------
Ran 1 test in 3.572s

OK

So I think the issue is with Ian's environment and not the software stack.
He should always assume that it is his environment before trying to get
others involved and spending more time, per Michael's comments. Linux and
all of the variations are tricky and do consume a lot of extra time that
could be spent developing in the supported environment.

Hi all,

I think Stephen has found an issue with Ubuntu CouchDB and is working on it.

The bigger question is why do we allow developers to work with environments
other than our standard development enviornment (MacOS Snow Leopard) and our
standard deployment environment (buildbot or hopefully soon CentOS 6.2)?

Working on Ubuntu and setting thigns up there burns cycles (see Ian's "spent
a day here and a day there). If it's Jamie doing it for the production
environment it's one thing. If it's a developer doing it by themselves, it's
wasted time. Burning time here and there...

Thanks,
Michael
