From: Steven Parkes Date: 2010-02-12T04:12:18+09:00 Subject: [ANN] johnson 2.0.0 prerelease 1 johnson version 2.0.0.pre1 has been released! * * Johnson wraps JavaScript in a loving Ruby embrace. It embeds the Mozilla SpiderMonkey JavaScript runtime as a C extension. The 2.0.0 prerelese series include TraceMonkey, the evolution of SpiderMonkey, which includes among other things a trace-based JIT compiler for JavaScript. In current prereleases the JIT is enabled for 320bit builds and disabled for 64-bit builds (as they are in the Mozilla builds). This prerelease includes TraceMonkey from the Firefox 3.6 build branch and fixes all known issues with split global support. Since it's a pre-release, you need to give gem the --prerelease flag to install it, i.e., gem install johnson --prerelease Because it's a prerelease gem, you may need to manually install gem dependencies. The gem install will tell you if you need to. The prerelease code is in the unstable branch of the git repo. Changes: === 2.0.0.pre1 / 2010-02-11 * Split global fix; covers all known issues * Fix build so enabling SM debugging doesn't cause SEGVs * bring in patched SM 1.9.2 (from Firefox 3.6)
