From 2b0eb3fac319a17dd92903106d501f0f06df871f Mon Sep 17 00:00:00 2001 From: Samuel Gaist Date: Mon, 30 Jan 2017 00:04:08 +0100 Subject: Remove use of QRegExp from QSharedMemory This patch updates the code from QSharedMemory to remove the use of the deprecated QRegExp class. It also updates the unique key test to avoid change of behavior going undetected.
