From 43a245bde318545ea75ca4ce7894395c1cf9b32a Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 16 Sep 2013 07:13:38 +0000 Subject: [PATCH] data: Be explicit in data_db check The if statement current causes the size of parent to be calcuated which is like a len() operation on a datastore. Since we're only interested whether the value is none, checking explictly for this gives a small performance gain.
