From 84cb00036fb59cf0ff305dcc27551f0519b5098c Mon Sep 17 00:00:00 2001 From: Gary Gibbons Date: Wed, 4 Jul 2012 09:40:19 -0400 Subject: [PATCH] git p4: refactor diffOpts calculation P4Submit.applyCommit() To avoid recalculating the same diffOpts for each commit, move it out of applyCommit() and into the top-level run(). Also fix a bug in that code which interpreted the value of detectRenames as a string rather than as a boolean.
