[ruby-core:30885] [Bug #3478] Excruciatingly slow pathname implementation

From: Stephen Touset <redmine@...>
Date: 2010-06-24 20:33:51 UTC
List: ruby-core #30885
Bug #3478: Excruciatingly slow pathname implementation
http://redmine.ruby-lang.org/issues/show/3478

Author: Stephen Touset
Status: Open, Priority: Normal
Category: lib
ruby -v: ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-darwin10.3.1] 

In writing a pure-Ruby git implementation, I discovered with rprof that using Pathname was the source of a huge proportion of my library's running time. Recently, Rails contributor Jos辿 Valim discovered a similar situation in Rails. Anecdotally, removing Pathname resulted in a speedup from 6s to 3s on a single request. Here's his commit removing some Pathname usage from Rails:

    http://github.com/rails/rails/commit/69abbe893413c99808c8cebd2f1d468c7921c573

I have rewritten Pathname, and the project is on GitHub.

    http://github.com/stouset/pathname3/

I've included the rewrite as a patch. It's backwards-compatible with the existing Pathname class, and passes RubySpec and MRI tests.
