Yesterday, the second milestone of the Icehouse development branch of Ceilometer has been released and is now available for testing and download. This means the first half of the OpenStack Icehouse development has passed!Read More
The Ceilometer project supports various database backend that can be used as storage. Among them are MongoDB, SQLite MySQL, PostgreSQL, HBase, DB2… All Ceilometer's code is unit tested, but when dealing with external storage services, one cannot be sure that the code is really working. You could be inserting data with an incorrect SQL statement, or in the wrong table. Only having the real database storage running and being used can tell you that.Read More
Last week, the third and last milestone of the Havana development branch of Ceilometer has been released and is now available for testing and download. This means the end of the OpenStack Havana development time is coming, and that the features are now frozen.Read More
I've been hacking on Python for a lot of years now, on various project. For the last two years, I've been heavily involved in OpenStack, which makes an heavy usage of Python.
Once you start working with a hundred of hackers, on several software and libraries representing more than half a million source lines of Python, things change. The scalability, testing and deployment problems inherent to a cloud platform meddle with everything in designing components.Read More
Doing code reviews is a great way to discover things that people might struggle to comprehend. While proof-reading OpenStack patches recently, I spotted that people were not using correctly the various decorators Python provides for methods. So here's my attempt at providing me a link to send them to in my next code reviews. :-)Read More
