[jira] [Resolved] (TORQUE-233) Exception translation
[ https://issues.apache.org/jira/browse/TORQUE-233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Fox resolved TORQUE-233.
-------------------------------
Resolution: Fixed
Fix Version/s: 4.0-beta2
Assignee: Thomas Fox
Deadlock detection does not work for hsqldb, I have not been able to produce a deadlock detected by hsqldb, the classical case for table-based locking(write table 1 transaction1, write table 2 in transaction 2, write teable 2 in transaction 1, write table1 in transaction 2) just waits indefinitely with no deadlock detected.
Everything else works.

> Currently, there is no portable way to determine the reason of an Exception.
> E.g. if an exception occurs during saving, it could be due to a unique key violation.
> It would be nice such a Violation would result in a special subclass of TorqueException, so the reason could be determined in a way portable across databasess
> (Currently one can look at the root cause of the Torque exception and then e.g. form ysql check whether it's a MySQLIntegrityConstraintViolationException, but of course this is not portable across databases)
