#2680: check licenses in CactusFoo repositories

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: enhancement
 Priority: minor
Component: 

Cactus code is expected to be LGPL \(or more freely I guess\) licensed. Initially what was used was GPL with a an exemption:

> This thorn is \(c\) Copyright the authors listed in the sources files. This  
> thorn is distributed under the GNU GPL with the specific exception that  
> the GNU GPL does not migrate to code linking to or using infrastructure  
> from this thorn.  
>   
> - The Cactus Team [cactusmaint at cactuscode.org](mailto:cactusmaint at cactuscode.org)

eg in cactusbase/Boundary. This was then changed to be LGPL \(which amounts to the same exemption\) around 2009 and also around 2015 \(see eg commit logs in cactus\* repos\).   
However some repos were missed and either show no license information at all in README or have LGPL \(in the README file\) but the GPLv2 COPYING file \(with or without the manual exemption\). Affected is eg Formaline which lists no license in its README file, but has a commit [5de0764](https://bitbucket.org/cactuscode/cactusutils/commits/5de0764e67538342e517b94eb7312da7824866da) "Formaline: Make Formaline GPL." of [cactusutils](https://bitbucket.org/cactuscode/cactusutils) declaring it GPL.

To change license, one actually needs permission from all copyright holders. For Formaline the list of authors \(but not necessarily copyright holders, that may actually be the respective universities and employers\) is:  
  
Barry Wardell  
Erik Schnetter  
Frank Löffler  
Ian Hinder  
Roland Haas  
Steven R. Brandt  
Thomas Radke

‌

but not all can be asked for permission anymore.
