Bug description:mssql_fetch_batch tries to allocate 4GB memory
Description:
------------
Fatal error: Allowed memory size of X bytes exhausted (tried to allocate
4294967296 bytes)
The error above is being shown when using mssql_fetch_batch on two
different connections. Look at the test script example.
Test script:
---------------
<?php
function fetchAssoc($link)
{
$res = mssql_fetch_assoc($link);
if ($res === false) {
if (mssql_fetch_batch($link) > 0) {
$res = mssql_fetch_assoc($link);
}
}
return $res;
}
$link1 = mssql_connect('host', 'user', 'pwd');
mssql_select_db('db', $link1);
$link2 = mssql_connect('host', 'user', 'pwd');
mssql_select_db('db', $link2);
$result1 = mssql_query("SELECT TOP 2 * FROM table", $link1, 1);
while ($row1 = fetchAssoc($result1)) {
echo "Row from 1 result\n";
$result2 = mssql_query("SELECT TOP 2 * FROM table2", $link2);
while ($row2 = fetchAssoc($result2)) {
echo "Row from 2 result\n";
}
}
echo "Done";
Expected result:
----------------
Row from 1 result
Row from 2 result
Row from 2 result
Row from 1 result
Row from 2 result
Row from 2 result
Done
Actual result:
--------------
Row from 1 result
Row from 2 result
Row from 2 result
