Potential Licensing Fiasco #145

Closed Digi59404 closed 8 years ago

Digi59404 commented 8 years ago

Valum is licensed under LGPL V3. CTPL is licensed under GPL V3.

Because of the way GPL is licensed and the inclusion of GPL code into Valum. Any works created with Valum must be licensed under GPL. There is a graph for this on GNU that explains it. http://www.gnu.org/licenses/gpl-faq.html#AllCompatibility

In the future there may be much confusion regarding this or someone may use Valum and violate the GPL unknowingly. To resolve this potential fiasco - You should either license Valum as GPL - Or Replace CTPL with something like Mustache (Of which there were plans).

It is effectively the case. I will remove the CTPL code from Valum and distribute it separately under GPLv3.

The plan was to not ship a templating engine, but provide an implementation of Mustache that would be very friendly with GIO stream API. I'm working on this actually and it should be ready in a couple of weeks.

@arteymix Thank you - I hate to bring this up, and be the guy that put's in /that/ ticket. But I was looking to possible use Valum and I uncovered this.

Regarding Mustache - Do you need help? I noticed the repo is empty for the most part but i'd be interested in helping.

arteymix commented 8 years ago

@Digi59404 it's all right, had to be done anyway.

If you don't mind, of course you can get involved. I will upload a prototype in a few days, but in short:

FWIW, I (as CTPL author) would probably be happy to re-license under LGPL if the current license prevents you from using the library. And actually, as CTPL doesn't really create something totally unseen before, it might make even more sense to make it LGPL.

Digi59404 commented 8 years ago

@b4n Hey man - So, The reason I brought this up is because my company is looking to working and building out a CMS based on Vala. We were looking at Valum and Ambition. We chose Ambition because we as a company can't ship a CMS to a client under GPL. That would mean all their themes, assets, designs, etc all were GPL.

I know this is a common problem in the FOSS community and one reason why many ship code under MIT.

arteymix commented 8 years ago

@b4n shipping a templating engine defeats the idea of a micro-framework, I would rather see people integrate it (or any other templating engine) directly in their project

@Digi59404 Valum still need some work to become production-ready (missing critical features like multipart stream #105), so you would have clearly hit a wall at some point of your development

I like the MIT, but in the context of a GLib ecosystem, it's nice to remain around the LGPL license.
