Enable continuous integration with travis-ci.

[jimjh]

As the number of contributors increase, it becomes more important to make sure that everyone is able to get started quickly on a clean slate, where 'clean' is defined by the unit tests and integration tests. It also avoids "but it runs on my machine!" scenarios. This pull request adds a travis configuration file which instructs travis-ci to run the tests. A badge indicating the status is included in the README. Rails is a great example of a project using travis successfully.

• travis-ci
• continuous integration
• current build status, from my fork

Note that you will need to enable github to notify travis whenever a push is made.

At this point, it appears that py2.6 doesn't work too well with expectFailures, and that some of the integration tests are failing. I would like to have your help with these.

@jimjh CI would be wonderful - I'd never seen TravisCI before (what's with all the butler references?)

What are the limitations as to what you can run in TravisCI. For the integration tests we require a running ZooKeeper and Kafka broker(s). This requires running the sbt targets in kafka-src.

Just looked at the yml file and I see you have the SBT commands in there - very cool. I will definitely check this out.

[jimjh]

Great! Travis and Github integrates nicely and even runs tests on pull requests. Detailed docs are available here.

Let's work on getting the tests to pass next.

[mumrah]

@jimjh yup. @mrtheb is working on updating the tests with the latest 0.8 Kafka version (See #51).

[mrtheb]

@jimjh pretty nice, I was leaning towards that as well. Any idea if Travis-CI finally has support for windows? (I know... I shouldn't do that but that's an unfortunate requirement of mine :-()

Can you help enable it in the 0.8 branch?

[mumrah]

@jimjh well since it's Python it should "just work" on Windows, right? ;)

[jimjh]

@mrtheb No, I don't think they support windows yet. But it looks like they are working on it.

@mumrah That was what Java said. Heh.

[jimjh]

I believe travis-ci runs all branches by default. Anw, I don't think I have access to the repository settings on travis since I am not a committer.

@mumrah python multiprocessing seems to have issues with windows :-P
so windows support will be good.
