ruby-1.9.3-p194 cumulative performance patch.

Patched ruby 1.9.3-p194 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p194 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

3.0.x monkeypatch for fixing Invalid Char 500s
# Fix for a Rails - Ruby 1.9 bug
# Rails Router, now that it's UTF-8 default, blows up when routing requests
# with invalid chars in the URL; it should properly return a 400 error
# Have to monkey-patch the fix in, since it's not scheduled for release until
# Rails 4.0.
# Adapted Andrew White (pixeltrix)'s fix at
# https://github.com/rails/rails/commit/3fc561a1f71edf1c2bae695cafa03909d24a5ca3,
# but edited to work in 3.0.x.
# 3.1.x, 3.2.x compatibility unknown
