Description:
------------
The session management differs in some cases when there is an uncommited transaction.

Run the test case with and without the parse/execute lines commented.  When the lines are commented out an explicit oci_close() or the end of f1() causes the connection to be closed.  With the lines active the sessions remain open and the transactions are not rolled back.

A third error case is if the sample script is changed to use oci_new_connect(). Confusingly the explict close has no effect but the end-of-scope will rollback and close the connection.

This may be a in implementation quirk of reference counting but it is a user level bug.  Oci_close() should always close when oci8.oci_old_close_semantics has its default value.  The cleanup at end-of-scope should be consistent regardless of the user transaction state.

Reproduce code:
---------------
<?php

// Create this table first: create table cj1 (a number);


$v = ini_get('oci8.old_oci_close_semantics');
echo "oci8.old_oci_close_semantics is $v\n";

ociinternaldebug(1);

echo "Test 1\n";

$c1 = oci_new_connect("hr", "hr", "localhost/XE");

echo "Do statement\n";
$s1 = oci_parse($c1, "insert into cj1 values(1)");
var_dump(oci_execute($s1, OCI_DEFAULT));

echo "Before close: transaction should rollback and connection should be closed\n";

ocilogoff($c1);

echo "After close\n";

echo "Test 2\n";

function f1()
{
    echo "In f1()\n";
    $c2 = oci_new_connect("hr", "hr", "localhost/XE");

    if (!$c2) {
        $m = ocierror();
        echo $m['message'];
        exit;
    }
    else {
        echo "Connection succeeded\n";
    }

    echo "Do statement\n";
    $s2 = oci_parse($c2, "insert into cj1 values(1)"); 
    var_dump(oci_execute($s2, OCI_DEFAULT));

    echo "Before end of scope\n";
}

f1();
echo "after f1() call - end of scope\n";

echo "End of script\n";

?>
