Thanks! I'll find time to test this with the latest MySQL to confirm this behavior. BTW. Is there any documentation on the MySQL site about this behavior? |

With recent versions of MySQL, the server, after receiving COM_QUIT, can send an optional OK packet. But this driver close the TCP connection before reading it. So in the server LOG there are many errors like this:
There is no lost data, so the error is harmless. But it is "scaring" reading these errors in the LOG.
This patch is compatible also with older version of MySQL not sending the OK packet, like this
mysql Ver 15.1 Distrib 5.5.60-MariaDB, for Linux (x86_64) using readline 5.1Many thanks in any case for the wonderful work!
