Forwarding a question from openstack-dev about the implications of our use of mysql-python, which is a GPLv2 licensed library. We've had some previous threads about GPL licensed dependencies e.g. http://lists.openstack.org/pipermail/openstack-dev/2013-March/006772.html http://lists.openstack.org/pipermail/openstack-dev/2013-March/006792.html http://lists.openstack.org/pipermail/openstack-dev/2013-March/006908.html Mark. -------- Forwarded Message -------- > From: Chris Friesen <chris.friesen at windriver.com> > Reply-to: "OpenStack Development Mailing List \(not for usage > questions\)" <openstack-dev at lists.openstack.org> > To: OpenStack Development Mailing List (not for usage questions) > <openstack-dev at lists.openstack.org> > Subject: [openstack-dev] mysql/mysql-python license "contamination" > into openstack? > Date: Thu, 12 Jun 2014 12:13:05 -0600 > > Hi, > > I'm looking for the community viewpoint on whether there is any chance > of license contamination between mysql and nova.
