From 48467f2d8cba8da2589cb1e480e4ed40199626d9 Mon Sep 17 00:00:00 2001 From: Tijl Coosemans Date: Fri, 26 Nov 2010 10:11:08 +0100 Subject: QKqueueFileSystemWatcherEngine: Handle kevent(2) returning EINTR. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The worker thread exits whenever the kevent call returns an error, but in the case of EINTR (interrupted by signal) it should just call kevent again. Otherwise for instance, attaching a debugger to the process causes the worker thread to exit because of the SIGSTOP it receives.
