示例1: visit
void CmdInterpreter::visit(ProxyCmdRollback &cmd)
{
TxnHandle *pTxnHandle = getTxnHandle(cmd.getTxnHandle());
SharedDatabase pDb = pTxnHandle->pDb;
// block checkpoints during this method
bool txnBlocksCheckpoint = !pTxnHandle->readOnly && pDb->shouldForceTxns();
SXMutexSharedGuard actionMutexGuard(
pDb->getCheckpointThread()->getActionMutex());
if (pDb->areSnapshotsEnabled()) {
SnapshotRandomAllocationSegment *pSegment =
SegmentFactory::dynamicCast<SnapshotRandomAllocationSegment *>(
pTxnHandle->pSnapshotSegment);
pSegment->rollbackChanges();
}
if (cmd.getSvptHandle()) {
SavepointId svptId = getSavepointId(cmd.getSvptHandle());
pTxnHandle->pTxn->rollback(&svptId);
} else {
pTxnHandle->pTxn->rollback();
deleteAndNullify(pTxnHandle);
if (txnBlocksCheckpoint && !pDb->areSnapshotsEnabled()) {
// Implement rollback by simulating crash recovery,
// reverting all pages modified by transaction. No need
// to do this when snapshots are in use because no permanent
// pages were modified.
pDb->recoverOnline();
}
