From 379862ec5a413e636d977a6ea3d618f0b3eafceb Mon Sep 17 00:00:00 2001 From: Steven Walter Date: Mon, 20 Feb 2012 09:17:54 -0500 Subject: [PATCH] git-svn.perl: fix a false-positive in the "already exists" test open_or_add_dir checks to see if the directory already exists or not. If it already exists and is not a directory, then we fail. However, open_or_add_dir did not previously account for the possibility that the path did exist as a file, but is deleted in the current commit. In order to prevent this legitimate case from failing, open_or_add_dir needs to know what files are deleted in the current commit. Unfortunately that information has to be plumbed through a couple of layers.
