Pavel Pereslegin updated IGNITE-19919:
--------------------------------------
Fix Version/s: 3.0.0-beta2
> org.apache.ignite.sql.ResultSet#close should close implicit transaction if any
> ------------------------------------------------------------------------------
>
> Key: IGNITE-19919
> URL: https://issues.apache.org/jira/browse/IGNITE-19919
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Alexander Lapin
> Assignee: Maksim Zhuravkov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> At the current moment, the transaction will be closed only if the cursor has
> read all the data:
> {code:java}
> org.apache.ignite.internal.sql.engine.AsyncSqlCursorImpl#requestNextAsync{code}
> in the case of an explicit ResultSet.close() call, the transaction will not
> be closed.
>
> Repoducerers within org.apache.ignite.internal.sql.api.ItSqlSynchronousApiTest
> {code:java}
> @Test
> public void resultSetCloseShouldFinishImplicitTransacion() throws
> InterruptedException {
> sql("CREATE TABLE TEST(ID INT PRIMARY KEY, VAL0 INT)");
> for (int i = 0; i < ROW_COUNT; ++i) {
> sql("INSERT INTO TEST VALUES (?, ?)", i, i);
> }
> IgniteSql sql = igniteSql();
> Session ses = sql.sessionBuilder().defaultPageSize(2).build();
> ResultSet rs = ses.execute(null, "SELECT * FROM TEST");
> assertEquals(1, ((IgniteImpl)
> CLUSTER_NODES.get(0)).txManager().pending());
> rs.close();
> assertEquals(0, ((IgniteImpl)
> CLUSTER_NODES.get(0)).txManager().pending());
> }{code}
> and
> {code:java}
> @Test
> public void
> resultSetCloseShouldFinishImplicitTransacionWithCursorTouchAfterClose()
> throws InterruptedException {
> sql("CREATE TABLE TEST(ID INT PRIMARY KEY, VAL0 INT)");
> for (int i = 0; i < ROW_COUNT; ++i) {
> sql("INSERT INTO TEST VALUES (?, ?)", i, i);
> }
> IgniteSql sql = igniteSql();
> Session ses = sql.sessionBuilder().defaultPageSize(2).build();
> ResultSet rs = ses.execute(null, "SELECT * FROM TEST");
> assertEquals(1, ((IgniteImpl)
> CLUSTER_NODES.get(0)).txManager().pending());
> Thread.sleep(300); // ResultSetImpl fetches next page in background, wait
> to it to complete to avoid flakiness.
> rs.close();
> assertThrowsWithCause(() -> rs.forEachRemaining(Object::hashCode),
> CursorClosedException.class);
> assertEquals(0, ((IgniteImpl)
> CLUSTER_NODES.get(0)).txManager().pending());
> }{code}
> Please, pay attention, that
> resultSetCloseShouldFinishImplicitTransacionWithCursorTouchAfterClose faisl
> only if client is used as entry point, meaning within
> ItSqlClientSynchronousApiTest only, but
> resultSetCloseShouldFinishImplicitTransacion fails both for client and
> server, meaning both for ItSqlClientSynchronousApiTest and
> ItSqlSynchronousApiTest.
