Indeed. We believe that archweb is in violation.
In the linked bug, I commented off-the-cuff that I didn't believe that
the 1st-party GPLv2 code interacted with the 3rd-party GPLv3 or Apache
2.0 code in a way that required license compatibility.
Upon further review of release_2017-01-02 (the last release that
Parabola has merged, and thus the last that I am familiar enough with
to speak confidently about), I no longer believe that to be true.
A listing of all 3rd-party JS, and its license:
- Bootstrap 2.1.1 (+change from Dan McGee) : Apache 2.0
- jQuery 1.8.3 : MIT
- tablesorter 2.7 : MIT / GPL dual-license
- D3 3.0.6 : 3-clause BSD
- konami.js c0f686e (+change from unknown author) : GPLv3
Note that without even being concerned with license compatibility,
archweb is currently in violation of konami.js, as it does not
include, link to, or in any way provide instructions on how to obtain
non-minified source code. This is especially grievous, as it includes
(minor) changes that are not present in any non-minified version that
I have found. (We already patch to fix this in Parabola's fork; after
identifying the minifier used (UglifyJS 2.2), I backed-out to
reproduce the source changes (which I linked above).)
Now, as Andrew Gregory agreed, the GPLv3 and Apache 2.0 licenses of
konami.js and Bootstrap are incompatible with archweb's GPLv2 license.
The 3rd-party files of concern are:
Additionally, the following file includes both 1st-party GPLv2 code,
and minified versions of bootstrap-typeahead.js and konami.js:
This 3rd-party code is called by GPLv2-licensed archweb code in the
As Eli Schwartz noted elsewhere in the thread, after it was copied in
to archweb, konami.js has since re-licensed to the MIT license.
However, that does not cover the changes of unknown authorship that
were present when konami.js was first add to archweb. There's a good
chance that the author there is Dan McGee (who added the file to
archweb), but I'm not certain of that.

Bootstrap has also since re-licensed so that 3.1 and later are MIT
licensed; however, bootstrap-typeahead.js was only ever present in
Bootstrap 2.x; and was therefore not covered in the re-license.
