From bb72fddebcf5ef6bed9d9c77d2317383a2a096ce Mon Sep 17 00:00:00 2001 From: Ulf Hermann Date: Wed, 16 Aug 2017 12:47:07 +0200 Subject: Fix remaining race conditions in QQmlDebugProcess If the process generated a "Cannot listen" message before we waitForSessionStart(), we would never quit the nested event loop. Also, unrelated output was not always forwarded, and the event loop was not terminated when the process unexpectedly stopped. Also, the timer was started when the process started, not when we started waiting and we don't want to report the process as crashed if we kill it ourselves. In turn, we remove the remaining blacklists.
