From 1d13e9f600986b7ced8db37a9a9c4967ee7ff9d5 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Fri, 19 Nov 2010 18:46:22 -0600 Subject: [PATCH] vcs-svn: Eliminate node_ctx.srcRev global The srcRev variable is only used in handle_node(); its purpose is to hold the old mode for a path, to only be used if properties are not being changed. Narrow its scope to make its meaningful lifetime more obvious. No functional change intended. Add some tests as a sanity-check for the simplest case (no renames).
