Julius Stroffek updated DERBY-2508:
-----------------------------------
Attachment: d2508.stat
d2508.diff
I am attaching a patch that solves also the problem of the currently running
statement. A brief explanation of changes in classes follows.
I ran derbyall and suites.All without failures.
Please review the patch. Any comments or suggestions are welcomed.
====================
The cancelation task is driven/maintaned in XATransactionState class instance.
A brief explanation of changes in classes:
EmbedConnection:
---
Comments to xa_rollback/commit/prepare added stating that these functions should
not be called directly but XATransactionState.xa_rollback/commit/prepare should
be called instead because these do also timer task maintanance/cancallation.
cancelRunningStatement - added a method to cancel the current running statement.
EmbedXAResource:
---
calling XATransactionState.xa_rollback/commit/prepare instead
of XATransactionState.conn.xa_rollback/commit/prepare. The new methods call
the original methods and also some more code related to timeouts was added.
returnConnectionToResource, removeXATransaction - changed the visibility
to package because we have to call the functions from XATransactionState
to perform correct global transaction disassociation.
set/getTransactionTimout - code added to support the transaction timeout.
start - A scheduling of a cancellation task was added.
XATransactionState:
---
CancelXATransactionTask class - added and represents a timeout task to be
executed.
xa_rollback/commit/prepare - wrap calls to conn.xa_rollback/commit/prepare
and contain timout task maintanance/cancellation code.
scheduleTimeoutTask - method added to schedule a timout task.
Property:
---
derby.jdbc.xaTransactionTimeout - new property added which sets up the default
value for XA transaction timeout.
XATransactionTest:
---
Added a test for XA transaction timeout behaviour in different stages/states of
a global transaction including cancellation of a running statement.
> Implement the XA transaction timeout support for embedded driver.
