Arjun Mishra created SENTRY-2047:
------------------------------------
Summary: isTableEmptyCore method ins SentryStore has references to
MAuthzPathsMapping when it should be generic
Key: SENTRY-2047
URL: https://issues.apache.org/jira/browse/SENTRY-2047
Project: Sentry
Issue Type: Bug
Components: Sentry
Affects Versions: 2.0.0
Reporter: Arjun Mishra
Assignee: Arjun Mishra
Current isTableEmpty implementation is below
{noformat}
private boolean isTableEmptyCore(PersistenceManager pm, Class clazz) {
Query query = pm.newQuery(clazz);
query.addExtension(LOAD_RESULTS_AT_COMMIT, "false");
// setRange is implemented efficiently for MySQL, Postgresql (using the
LIMIT SQL keyword)
// and Oracle (using the ROWNUM keyword), with the query only finding the
objects required
// by the user directly in the datastore. For other RDBMS the query will
retrieve all
// objects up to the "to" record, and will not pass any unnecessary objects
that are before
// the "from" record.
query.setRange(0, 1);
return ((List<MAuthzPathsMapping>) query.execute()).isEmpty();
}
{noformat}
We seem to be casting query.execute to a List<MAuthzPathsMapping> when there is
no need for it
