示例1: runTransaction
void Database::runTransaction(
SQLTransactionCallback* callback,
SQLTransactionErrorCallback* errorCallback,
VoidCallback* successCallback,
bool readOnly,
const ChangeVersionData* changeVersionData)
{
ASSERT(executionContext()->isContextThread());
// FIXME: Rather than passing errorCallback to SQLTransaction and then
// sometimes firing it ourselves, this code should probably be pushed down
// into Database so that we only create the SQLTransaction if we're
// actually going to run it.
#if ENABLE(ASSERT)
SQLTransactionErrorCallback* originalErrorCallback = errorCallback;
#endif
SQLTransaction* transaction = SQLTransaction::create(this, callback, successCallback, errorCallback, readOnly);
SQLTransactionBackend* transactionBackend = runTransaction(transaction, readOnly, changeVersionData);
if (!transactionBackend) {
SQLTransactionErrorCallback* callback = transaction->releaseErrorCallback();
ASSERT(callback == originalErrorCallback);
if (callback) {
OwnPtr<SQLErrorData> error = SQLErrorData::create(SQLError::UNKNOWN_ERR, "database has been closed");
executionContext()->postTask(BLINK_FROM_HERE, createSameThreadTask(&callTransactionErrorCallback, callback, error.release()));
