Anssi Kääriäinen 50328f0a61 Fixed #19861 -- Transaction ._dirty flag improvement ... There were a couple of errors in ._dirty flag handling: * It started as None, but was never reset to None. * The _dirty flag was sometimes used to indicate if the connection was inside transaction management, but this was not done consistently. This also meant the flag had three separate values. * The None value had a special meaning, causing for example inability to commit() on new connection unless enter/leave tx management was done. * The _dirty was tracking "connection in transaction" state, but only in managed transactions. * Some tests never reset the transaction state of the used connection. * And some additional less important changes. This commit has some potential for regressions, but as the above list shows, the current situation isn't perfect either.		2013-02-27 17:54:27 +02:00
