With NHibernate and Transaction do I rollback on commit failure or does it auto rollback on single c
- by mattcodes
I've built the following Dispose method for my Unit Of Work which essentially wraps the active NH session & transaction (transaction set as variable after opening session as to not be replaced if NH session gets new transaction after error)
public void Dispose()
{
Func<ITransaction,bool> transactionStateOkayFunc =
trans => trans != null && trans.IsActive && !trans.WasRolledBack;
try {
if(transactionStateOkayFunc(this.transaction))
{
if (HasErrored)
{
transaction.Rollback();
}
else
{
try
{
transaction.Commit();
} catch (Exception)
{
if(transactionStateOkayFunc(transaction)) transaction.Rollback();
throw;
}
}
}
} finally
{
if(transaction != null) transaction.Dispose();
if(session.IsOpen) session.Close();
}
I can't help feeling that code is a little bloated, will a transaction automatically rollback is a discrete Commit fails in the case of non-nested transactions?
Will Commit or Rollback automatically Dipose the transaction? If not will Session.Close() automatically dispose the associated transaction?
