<span class="c1"># When a server connection is lost and a query is attempted, most of</span>
<span class="c1"># the time the query will raise a SERVER_LOST exception, then at the</span>
<span class="c1"># second attempt to execute it, the mysql lib will reconnect and</span>
<span class="c1"># succeed. However is a few cases, the first attempt raises the</span>
<span class="c1"># SERVER_GONE exception, the second attempt the SERVER_LOST exception</span>
<span class="c1"># and only the third succeeds. Thus the 3 in the loop count.</span>
<span class="c1"># If it doesn't reconnect even after 3 attempts, while the database is</span>
<span class="c1"># up and running, it is because a 5.0.3 (or newer) server is used</span>
<span class="c1"># which no longer permits autoreconnects by default. In that case a</span>
<span class="c1"># reconnect flag must be set when making the connection to indicate</span>
<span class="c1"># that autoreconnecting is desired. In MySQLdb 1.2.2 or newer this is</span>
<span class="c1"># done by calling ping(True) on the connection.</span>
