Bug description: Connection problems after SQL error
Description:
------------
Unexpected behaviour when SQL queries fail.
Reproduce code:
---------------
<?
$db_host = "";
$db_user = "";
$db_pass = "";
$db_base = "";
function error_handler($errno, $errmsg)
{
echo $errmsg;
exit(1);
}
// script will hang on sql error
$dbconn = mssql_connect($db_host, $db_user, $db_pass);
// refreshes will cause sql server to refuse selection of db
//$dbconn = mssql_pconnect($db_host, $db_user, $db_pass);
mssql_select_db($db_base, $dbconn);
error_reporting(0);
set_error_handler("error_handler");
if($_GET['error'] == "plain")
trigger_error("Error", E_USER_ERROR); // produce error
else if($_GET['error'] == "sql")
mssql_query("SELECT asdf FROM asdf"); // produce sql error
?>
Expected result:
----------------
mssql_connect(): On SQL error the script should not hang but finish.
mssql_pconnect(): On SQL error further connection requests should not
fail.
Actual result:
--------------
If an SQL error occurs, database connections established with
mssql_pconnect() get lost. New connection requests fail with
"mssql_select_db() [function.mssql-select-db]: Unable to select
database".
When using mssql_connect() instead of mssql_pconnect(), execution of the
resp. PHP script will hang (up to 5 minutes). The error handler will
finish its job, but PHP does not close the connection to the browser - it
keeps "loading" (although no data is being sent anymore).
