Inappropriate exception type thrown on failure to connect to MySQL server
Closed, ResolvedPublic


Client errors in DatabaseBase->query() are thrown as DBQueryError exceptions, even when the error is clearly related to connectivity, and would be better represented by a DBConnectionError exception. This way, we wouldn't give the goofy suggestion to run maintenance/update.php when we hit a 2013 ("Lost connection to MySQL server during query") client error.

Actually using DBConnectionError has it's own pitfalls and changes needed, so the above change just fixes the error message string, which should be fine.
