Revision as of 17:08, 28 December 2012
Switch ZNC from GPL 2 to another license
See https://github.com/znc/znc/issues/218
What we want?
- Ability to use stuff licensed under Apache license in ZNC
- Ability to use stuff licensed under GPL 2 license in ZNC
- Anything else?
The list
GPL 3
Pros:
- Requires distributed changes to ZNC to be released under the GPL3.
Cons:
- Incompatible with GPLv2 and thus conflicts with "What we want": [1]
- "Stigma" of being a "viral" license, prevents some people or businesses from using or contributing back.
LGPL 3
Pros:
- Requires distributed changes to ZNC to be released under the LGPL3.
Cons:
- ZNC is not a library (Don't need to be a library to use the "Lesser" GPL license. Jreese (talk) 17:19, 20 December 2012 (UTC))
- "Stigma" of being a "viral" license, prevents some people or businesses from using or contributing back.
Apache 2.0
Pros:
- Most liberal license that still protects any project trademarks.
Cons:
- Allows distributed changes to ZNC to be re-licensed under different terms, or even stay closed-source.
BSD (2-clause or 3-clause?)
Pros:
- Extremely liberal license.
- 3-clause license restricts usage of project or contributor names for endorsing derived projects.
Cons:
- Allows distributed changes to ZNC to be re-licensed under different terms, or even stay closed-source.
MIT
Pros:
- Extremely liberal license.
Cons:
- Basically identical to 2-clause BSD license.
- Allows distributed changes to ZNC to be re-licensed under different terms, or even stay closed-source.
Anything else?
Comments
- The goal of being able to use both Apache-licensed and GPL2-licensed code in ZNC is not going to be possible. Apache license is not compatible with GPL2-only projects, and GPL2-only is not compatible with GPL3 projects. Jreese (talk) 17:26, 20 December 2012 (UTC)
- Even if the codes are running in separate processes? ([2] [3]) DarthGandalf (talk) 18:18, 20 December 2012 (UTC)
- In the case of Iris/Qwebirc, as long as the ZNC code itself is not linking to any of the GPL2 code, then there is no conflict; at that point, you are merely redistributing the GPL2 projects along with ZNC.
