PG transport can send multiple read messages -------------------------------------------- Key: TEIID-5658 URL: https://issues.jboss.org/browse/TEIID-5658 Project: Teiid Issue Type: Bug Components: ODBC Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Major Fix For: 12.1, 12.0.1, 11.2.3 The code is allowing for a sequence of events such as: 2019-02-13 12:26:55.159 org.teiid.ODBC TRACE NIO1 invoking server method: execute [, 0] 2019-02-13 12:26:55.163 org.teiid.ODBC TRACE NIO1 invoking client method: sendResults [null, org.teiid.jdbc.ResultSetImpl@1a79693d, [org.teiid.odbc.PGUtil$PgColInfo@79f0f194], org.teiid.client.util.ResultsFuture@64fb47b7, FORWARD, -1, false, null] 2019-02-13 12:26:55.163 org.teiid.ODBC TRACE Worker5_QueryProcessorQueue533 invoking client method: sendCommandComplete [select oid from pg_class where relname='pg_class', [1]] 2019-02-13 12:26:55.163 org.teiid.ODBC TRACE Worker5_QueryProcessorQueue533 invoking client method: ready [false, false] 2019-02-13 12:26:55.163 org.teiid.ODBC TRACE NIO1 invoking server method: sync null 2019-02-13 12:26:55.163 org.teiid.ODBC TRACE NIO1 invoking client method: ready [false, false] That is after execute we are immediately responding with results, command complete, and ready. Then we see a sync and respond with ready again. The first ready is not expected - it should not be issued until after the sync. The causes issues in the pg jdbc driver such as reporting that there is no result set. See TEIID-5425
