From d04b7972d891a51b4b4c09128431961fece52e75 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Wed, 30 Jun 2010 18:56:20 -0700 Subject: Use copyTo during checkout of files to working tree This way we can stream a large file through memory, rather than loading the entire thing into a single contiguous byte array.
