Bug description:Empty, but set session cookies cause warning and cause sessions
to not save
Description:
------------
If a session cookie is not set, a new session id will be created and all
works fine. However, if for some reason the session cookie is set, but an
empty string, session_start() throws a warning and custom session handlers
are called with an empty session id. In addition, no session cookies are
set.
Test script:
---------------
The test script involves setting empty cookies and such. This is the user
land workaround I am using for now.
if(isset($_COOKIE[ini_get("session.name")]) &&
empty($_COOKIE[ini_get("session.name")])){
// The cookie is empty. This is bad.
unset($_COOKIE[ini_get("session.name")]);
}
session_start();
Expected result:
----------------
An empty session cookie should be treated the same as an unset session
cookie.
Actual result:
--------------
Empty session cookies are treated as session ids, but warned and cause
sessions to not be saved.
