the problem occurred for 8-15 warnings (all kinds of queries matching "warnings & 0x08 == 0x08") revno: 929 revision-id: jan@mysql.com-20080730132545-fd13qfq1n6b9mn31 committer: jan@mysql.com timestamp: Wed 2008-07-30 15:25:45 +0200 message: decoding the EOF packet had server-status and warnings flipped (fixes #38458)
Description: Queries that cause more than 8 warnings to be returned hang within the proxy: mysql> select cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal); ^CAborted How to repeat: * connect to the proxy * select cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal), cast('foo' as decimal);
