Thanks to Kay, it is now much easier to contribute to the MySQL Proxy project. And it turns out you don't have to be a super C developer to help out.
Yes, you may think, you can report bugs, help answering questions, even submit Lua scripts. But there is another way you can contribute.
You can check out the blueprints for the Proxy and pick one that seems "simple" to implement. That's what I did. I went there and picked "Chassis/Proxy should have short names for often used options". It sounded simple enough for me, and I thought it would help me get more familiar with the source code.
After a few emails on the mailing list, I gather all the info I needed and created a branch to work on it.
It turned out not to be much work at all :), so after I pushed my changes to the branch I created on Launchpad, I proposed a merge and now I'm waiting for a code review and hopefully it will be part of the main Proxy branch.
No matter what your skill set is, there are plenty of ways to get involved on this project.
