Perl client using DBD:Pg hangs with resultset > 512 rows -------------------------------------------------------- Key: TEIID-1831 URL: https://issues.jboss.org/browse/TEIID-1831 Project: Teiid Issue Type: Bug Components: ODBC Affects Versions: 7.4.1 Environment: java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.10) (rhel-1.23.1.9.10.el5_7-x86_64) OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode) on Red Hat Enterprise Linux Server release 5.7 (Tikanga) Teiid 7.5 with a patch applied for issue TEIID-1812 Perl client running on either Fedora 16 or RHEL 5.7 Using perl-DBD-Pg-2.18.0-3.fc16.x86_64 Reporter: Graeme Gillies Assignee: Steven Hawkins Fix For: 7.6 We are using a simple perl script to connect to teiid and run a query, spitting out the results. Unfortunately we find that the perl client hangs forever when trying to execture/return a resultset > 512 rows, but 512 or less it runs fine The code for a test script is as follows {code} #! /usr/bin/perl use strict; use warnings; use DBI; my $db_type = 'Pg'; my $db_name = 'EngVDBF'; my $db_host = 'vdb.engineering.redhat.com'; my $db_port = 35432; my $user = 'teiid'; my $pass = 'teiid'; my $attr = { AutoCommit => 0, RaiseError => 1 }; my $dsn = sprintf( "dbi:%s:dbname=%s;host=%s;port=%s", $db_type, $db_name, $db_host, $db_port ); my $dbh = DBI->connect( $dsn, $user, $pass, $attr ); my $limit = ( $ARGV[0] ) ? "limit $ARGV[0]" : ""; my $query = <<QUERY; select bugs.bug_id, bugs.priority, bugs.bug_severity from BugzillaS.bugs bugs $limit QUERY my $sth = $dbh->prepare($query); $sth->execute(); while ( my @row = $sth->fetchrow_array() ) { print join( ',', map {"\"$_\""} @row ) . "\n"; } $sth->finish(); $dbh->disconnect(); {code} When running {noformat} ./teiid.pl 512 {noformat} Query runs fine, when we run {noformat} ./teiid.pl 513 {noformat} Client just sits there forever (the query actually has about 1800 odd rows returning). -- This message is automatically generated by JIRA.
