I did a quick wander thru the Torque code and saw one thing that did not look right to me. Here's some background first:
All of the Torque Transaction handling is built on the Transaction class. This is used primarily by the BasePeer methods like doUpdate(Criteria) and the like. These methods are the ones that automatically wrap the DB actions as a transaction with rollback. The first thing that didn't look right to me was that the Transaction.beginOptional(dbName, useTransaction) method is called with the useTransaction arg set to the value of criteria.isUseTransation(). This value is set to false by default. So, it seems that if you don't set this explicitly on your Criteria, you are not using really using transactions but you still have the Transaction try/catch code with commits and rollbacks. Shouldn't the default for isUseTransactions() be true and/or the code handle the false condition without calling the extra transaction methods? > -----Original Message----- > From: vivek sar [mailto:[EMAIL PROTECTED] > Sent: Saturday, March 25, 2006 4:44 AM > > Thanks Thomas for detailed explanation.
