[Pulp-dev] Pulp 3 Licensing

After looking into this some more I believe @Simon's observation that Pulp
is operating under GPLv2+ is correct. I don't believe there is ambiguity.
There was confusion though. Specifically we include the LICENSE file in
Pulp's repo (which is GPLv2), but it's the COPYRIGHT file that actually
names what licenses (GPLv2 or later, i.e. GPLv2+) Pulp is licensed as. The
LICENSE file is included as a convenience, but that doesn't mean its the
only license. I've updated the FAQ clarifying this and linking to the repos
where you can see it:
This means that Pulp plugins must be licensed as either GPLv2 or GPLv3.
Please raise any concerns if this is unclear or incorrect. This has been
clarified in the FAQ also.
@oleksander here is what I think that means for Apachev2 combinations.
Please tell me what you think. Have your pulp subclassed objects be GPLv3
since that is an option, and then that code is safe to combine with other
licensed code that is compatible with GPLv3. Apache v2 is compatible with
GPLv3. Galaxy is the effective "combination" of these two compatible
licenses into one larger software. Note that this is a combining of two
distinct license types into one software, but the licenses stay distinct
over time. The Apache 2.0 parts stay as Apache and the GPLv3 parts stay as
GPLv3. I wrote up this case on the FAQ also:
Feedback on the correctness or this information is welcome.
Please send remaining or additional concerns. We want to make sure we are
incorporating all the info and correct info as we look at this.
