From accfa46f9ba4966af57ac2bed36ac84de71d6396 Mon Sep 17 00:00:00 2001 From: Aaron Lehmann Date: Mon, 9 Nov 2015 15:33:05 -0800 Subject: [PATCH] Fix empty delete requests with Swift fs driver The Delete method lists objects under the given path and tries to delete all of them with a bulk delete request. If the path has no objects underneath it, the body of this request will be empty, which causes HTTP-level issues. Specifically, Go's HTTP client senses the empty request buffer and doesn't include a Content-Length, which causes the Swift server to fail the request. This commit fixes the problem by avoiding sending empty bulk delete requests. This is the correct thing to do anyway, since there's no reason to request deletion of zero objects.
