Thanks, I was working from memory and wasn't sure. So yes, it's a fully legit issue, and it basically means you can't use MySQL with any proprietary code. So if I create a thin wrapper around libmysql, release that wrapper under the BSD 2-clause license (which is listed among the valid licenses - at least, I'm guessing that they mean the 2-clause), and then use that wrapper in a proprietary project, is that valid? This is getting ridiculously messy, and I'm definitely glad now not using MySQL at work. > As far as python goes, there are at least two pure-python > implementations of the mysql protocol available: > > - https://github.com/petehunt/PyMySQL (MIT license) That should be perfectly legal then. You're not linking against any GPL'd code, you're just connecting via a TCP socket to a GPL application. Really, I don't see what GPLing the client library achieves, other than creating a mess for people. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
