Last week, we upgraded the github.com rails app to ruby 2.1.0 in
production.
While testing the new build for rollout, we ran into a number of bugs.
Most of
these have been fixed on trunk already, but I've documented them below
to help
anyone else who might be testing ruby 2.1 in production.

@naruse I think we should backport these patches to the ruby_2_1 branch
and
release 2.1.1 sooner rather than later, as some of the bugs are quite
critical.
I'm happy to offer any assistance I can to expedite this process.

In addition to the bugfix patches above, we're running the following
performance patches in production. These have proven quite stable in our
environment, so I encourage you to try them if you're running a large
ruby app.

- funny-falcon's st.c density patch
  https://github.com/github/ruby/commit/1e025cbd2f

- funny-falcon's st.c pool allocator
  https://github.com/github/ruby/commit/3d37e2b5a3

- funny-falcon's method cache patch
  https://github.com/funny-falcon/ruby/compare/trunk...
  proposed for trunk in #9262

- optimized Hash#[] and Hash#[]= with string literals
  https://github.com/github/ruby/commit/86946e72d7
  merged to trunk in #9382 (r44551)

Aside from the bugs above, our upgrade to 2.1 was very smooth. I'm happy
to
report that github.com is now running faster (and with less GC overhead)
than
ever before.
