Well, I checked the code, and it seems to wake up the thread using pthread_kill(thread, signal) for the 'kill connection-id' command. This should work fine also when using SO_SNDTIMEO for timeouts on the socket. Just send the signal to the thread blocking on the socket with SO_SNDTIMEO, and the blocking socket call will return with EAGAIN or similar. - Kristian. _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : maria-discuss@lists.launchpad.net Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp
