Operating system: Debian Squeeze
PHP version: 5.3.8
Package: Session related
Bug Type: Bug
Bug description:Limit to session_regenerate_id updates
Description:
------------
Was doing some debugging on our session class and wanted to start from
scratch on
a few tests so we came up with the following, just to see how frequently we
his
collisions using the default session configs.
It appears that session_regenerate_id quits regenerating after 114 runs,
after
which the function simply fails.
Test script:
---------------
$arr = array();
session_id();
session_start();
for( $i = 0; $i <= 100000; $i++ )
{
$ses = session_id();
if(!session_regenerate_id(true) ) {
exit;
}
echo "Session: ". $ses. "\n";
$arr[$ses]++;
}
print_r( array_count_values( $arr ) );
Expected result:
----------------
Every call to session_regenerate_id and then to session_id would result in
a new
ID, and without limit.
