https://gerrit.ovirt.org/#/c/51521/3/vdsm/virt/vmchannels.py
File vdsm/virt/vmchannels.py:
Line 53: self._epoll.unregister(fileno)
Line 54: except IOError as e:
Line 55: # We do not care if it has been previously removed from epoll
Line 56: # or is not tracked by epoll. The removal is exactly what we
Line 57: # want to achieve.
Lets move the the check before the comment, and log debug debug message if the fd was not registered (ENOENT)
Line 58: if e.errno != errno.ENOENT:
Line 59: raise
Line 60:
Line 61: def _handle_event(self, fileno, event):
Line 225: def unregister(self, fileno):
Line 226: """ Unregister an exist file descriptor from the listener. """
Line 227: self.log.debug("Delete fileno %d from listener.", fileno)
Line 228: with self._update_lock:
Line 229: # Threadsafe, fileno will be closed by caller
Please explain in the comment why this must be done here and not insie _do_del_channel
Line 230: self._unregister_fd(fileno)
