Re: [openstack-dev] new keystone developer
First of all, welcome! As Steve suggested, feel free to ask questions in #openstack-dev ... it seems there's almost always someone online with deep knowledge of keystone.

Keystone, along with all the other major infrastructure components in OpenStack, is a rather large project. I've read over the developer documentationhttp://docs.openstack.org/developer/keystone/#developers-documentation, but was hoping to get help with some questions. (1) Are there diagrams that describe how various classes, functions, etc. interact with one another? I've seen a few in the past, but they tend to get out of date quickly. At a high level, the application is structured as follows: Paste Pipeline - Routers - Controllers - Managers - Drivers / Backends (SQL, LDAP, KVS, etc) And that's been true since the essex release. There are a few code paths that deviate from this naming convention (such as keystone.auth), but they follow the same basic pattern regardless. Database migrations have relatively flat call stacks. Some tests have a rather challenging inheritance hierarchy that we're working to unwind. (2) What's the best way to debug keystone when editing existing code or adding? Tips from those who do this every day would be greatly appreciated. I feel like I'm one of the remaining few that doesn't use any fancy tools. I write tests, hammer on them repeatedly, and read tracebacks. (3) Is there a way to import large chunks (or, preferably, all) of keystone into iPython? This makes debugging super easy and would fit in nicely with my existing workflow with other projects. Sounds like Yuriy has the answer you're looking for here! (4) Any other tips / tricks to help jumpstart tinkering with code? I always encourage people to jump straight into gerrit and participate in some code reviews. It's the best way to get a sense of the direction of the project as it evolves, and at the end of the day, you'll be much better prepared to produce your own patch(es).

Re: [openstack-dev] new keystone developer
Hey Mario, Welcome and thanks for helping out! The developer docs are a great place to get started. #1 - Not sure if there is anything recent, but here is an old diagram: http://ilearnstack.files.wordpress.com/2013/04/keystone.png #2 - I would read up on the section (Running with PDB) http://docs.openstack.org/developer/keystone/developing.html#running-with-pdb it's what I do most often. #3 - I'll leave this to others #4a - We usually lurk in (and flood) the #openstack-dev channel, so just give us a shout there. (Bug any of the folks here: http://russellbryant.net/openstack-stats/keystone-reviewers-30.txt). #4b - Join us on Tuesdays for the Keystone weekly meeting. https://wiki.openstack.org/wiki/Meetings/KeystoneMeeting #4c - Blueprints: https://blueprints.launchpad.net/keystone Bugs: https://bugs.launchpad.net/keystone #4d - More of an FYI - Icehouse milestone 2 just ended, so there won't be any new API features landing in milestone 3. (Good time to keep an eye on bugs :) ) That's all I can think of for now.

I think you might find ipdb https://pypi.python.org/pypi/ipdb useful for you: it's run just like pdb but opens an iPython shell instead. -- Kind regards, Yuriy. graycol.gif___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
