From d3be0f88181b4904f5ceddb88043ef589d777c45 Mon Sep 17 00:00:00 2001 From: cjihrig Date: Fri, 10 Feb 2017 11:57:48 -0500 Subject: [PATCH] test: cover cluster error during dgram socket bind When a non-exclusive dgram socket is bound from a cluster worker, a handle is requested from the cluster module. This commit adds coverage for the case where an error occurs while retrieving the handle.
