Bug description: Change of Read($sess_id) to ($sess_id, $maxlifetime)
If I install a user save handler class
e.g. MySqlSessionHandler with methods Read, Write, GC etc.
MySqlSessionHandler::Read($sess_id) is always called before
MySqlSessionHandler::GC($maxlifetime)
This has the problem, that a session is read, which potentially would be
garbage collected.
Therefore it would be nice to get the $maxlifetime parameter also in Read
e.g. Read($sess_id, $maxlifetime)
This allows to return an empty session if it has timeouted.
For Clarification here are two Methods GC and Read with $lifetime
information
function Read($sess_id, $maxlifetime)
{
// beware of timouted sessions not yet gced
$time_stamp= time();
$removeDate= date("YmdHis", ($time_stamp - $maxlifetime));
$search_query= "SELECT * FROM $_session_table WHERE (session_id =
'$sess_id') and (last_accessed >= $removeDate)";
$result= @ mysql_query($search_query, $_connection);
if(!$result)
{
// No session found - return an empty string
return "";
}
else
{
// Found a session - return the serialized string
$row = mysql_fetch_array($result);
return $row["session_variable"];
}
}
function GC($max_lifetime)
{
global $_connection;
global $_session_table;
$time_stamp= time();
$removeDate= date("YmdHis", ($time_stamp - $max_lifetime));
$delete_query = "DELETE FROM $_session_table WHERE last_accessed <
$removeDate";
$result = @mysql_query($delete_query,$_connection);
return true;
}
