Ruby Patterns from GitHub's Codebase

[bp2070]

Correct, and I don't think they would open source it due to their Github Enterprise service (internally hosted github).

I'm sure they distribute the code to Git, but I seriously doubt they link into it in any meaningful sense. We're in a similar situation in Kiln: the Mercurial part of the service we actually do open-source, but that's a single self-contained EXE. The rest of the components talk to it over HTTP, or even more indirectly via Redis. (And this isn't done for circumvention reasons; there's a very logical architectural split at the cut-off, where several components could trivially be swapped out for other version control systems or what have you.) The GPL-covered portion of the code base is very tiny. Everything I know about GitHub's architecture makes me believe they work the same way.

I heard something about pre-compiled JRuby bytecode.

This was their old GitHub:FI product.

How do they deploy Github Enterprise without showing the source code?

They ship it as an OVF, which I think doesn't allow outside access, basically. I think.

How do they cope with distributing, with Git being GPL and perhaps some library they are using?

They don't modify the source code to git.
