I sent an email to FSF about this and they told me that the limitation of permissions to "the creation of products supporting the Unicode Standard" makes the code non-free.

I think I know how to fix it without breaking existing software written in Ruby so I'll try to prepare a patch.

History

Updated by Anonymous over 6 years ago

I made the fix available at https://gitorious.org/niitotantei/abslibre.git, branch issue-#674.

This fix completely removes the C code handling JSON from Ruby. A free variant written in pure Ruby is packaged instead (actually both the C and Ruby code are part of the same gem). I made a few adjustments here and there so the existing software should work fine. The fix is a bit ugly though; I had to include a prepackaged gem in the repository because I don't quite know how to build it during Ruby build process. Anyway, I did a few tests and it looks like Ruby's functionality isn't affected by the fix.

Upstream bug in Ruby: https://bugs.ruby-lang.org/issues/11844
Upstream bug in json gem: https://github.com/flori/json/issues/277

It seems that Unicode upstream has re-licensed everything to be DFSG (and thus FSDG) compatible, and we are now waiting on verification from the json gem devs that generator.c can be re-licensed.
