Hybrid Logic is pleased to announce the release of txMySQL, a native Twisted MySQL protocol implementation at https://github.com/hybridlogic/txMySQL
The bulk of this code is courtesy of _habnabit (thank you!), we just added authentication support and fixed a couple of bugs which were stopping the MySQL protocol parser working.
This works well enough to .fetchall() basic results sets and .query() any other MySQL statements you care to run. See example.py.
Feel free to fork, tweak, fix, use, report issues, etc.
