From c5e558a80ad27774b9984258a31fbf46a1d7c152 Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Mon, 11 Jan 2010 02:59:54 +0000 Subject: [PATCH] Remove empty directories when checking out a commit with fewer submodules Change the unlink_entry function to use rmdir to remove submodule directories. Currently we try to use unlink, which will never succeed. Of course rmdir will only succeed for empty (i.e. not checked out) submodule directories. Behaviour if a submodule is checked out stays essentially the same: print a warning message and keep the submodule directory.
