Ruby 1.9.3-p194 with DTrace probes, Perf Patches, and backported COW-friendly GC

Overview

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

Many thanks to funny-falcon for the performance patches and to Aaron Patterson for the DTrace instrumentation.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Ok, let's do this!

curl https://raw.github.com/gist/3808235/rbenv.sh | sh ; rbenv global 1.9.3-p194-dtrace

Warning: ruby*::vm_exec_core:function-* seem to be broken, causing SystemStackErrors in the ruby process you instrument.

Hey,

I'm getting a peculiar error trying to run your "let's do this" command.

Output is

Looks like libyaml compiled, then it blows up when starting to decompress ruby.

Seems like the tar for ruby extracts to build instead of ruby-1.9.3-p194-perf-dtrace as ruby-build is expecting.

Changing the ruby-build definition to

install_package "build" "http://cloud.github.com/downloads/burke/ruby/ruby-1.9.3-p194-perf-dtrace.tar.gz" combined_patch

works.
