Can the OpenStack CLA (https://review.openstack.org/static/cla.html) be used as a template for other projects (non-OpenStack)? Is there a "license" of the CLA itself? --John

Thanks all guys. Copy python code is really a bad idea. Now i have moved to re-use oslo.config iniparser[0][1], which works too. So we have no license issue, now. ;) [0] https://github.com/openstack/oslo.config/blob/master/oslo_config/iniparser.… [1] https://review.openstack.org/#/c/412101/5/ansible/action_plugins/merge_conf… On Tue, Jan 3, 2017 at 1:04 AM, Van Lindberg <van.lindberg(a)rackspace.com> wrote: > Thierry is correct in his analysis. > > > If you really want to copy it - which I don't suggest - then copy it over > into your repo, rename both the module and the class, and make your code > use your derived work. > > > Put a header at the top that says something like "Based on Python's > ConfigParser.py.

[kolla]is it OK to modify python code in OpenStack project?
by Jeffrey Zhang 02 Jan '17

Recently, Kolla project has requirement to modify[1] the python's ConfigParser.py code[0]. Python is using PSF license[3], which is GPL compatible. But OpenStack is using Apache License. Here is the diff view[2]. I want to make sure: is it OK to re-license ConfigParser.py? If not, what the solution?
