Last week we moved psycopg from Subversion to Bazaar. I did the migration using Gustavo Niemeyer's svn2bzr tool with a few tweaks to map the old Subversion committer IDs to the email address form conventionally used by Bazaar. The tool does a good job of following tree copies and create related Bazaar branches. It doesn't have any special handling for stuff in the tags/ directory (it produces new branches, as it does for other tree copies).

Yesterday Federico released version 2.0.7 of psycopg2 (a Python database adapter for PostgreSQL). I made a fair number of the changes in this release to make it more usable for some of Canonical's applications. The new release should work with the development version of Storm, and shouldn't be too difficult to get everything working with other frameworks. Some of the improvements include: Better selection of exceptions based on the SQLSTATE result field.

Marc uploaded a new revision of the Python DB-API 2.0 Specification yesterday that documents the new two phase commit extension that I helped develop on the db-sig mailing list. My interest in this started from the desire to support two phase commit in Storm – without that feature there are far fewer occasions where its ability to talk to multiple databases can be put to use. As I was doing some work on psycopg2 for Launchpad, I initially put together a PostgreSQL specific patch, which was (rightly) rejected by Federico.
