13 * After calling session_name(), we won't find the progress data anymore.
15 * https://bugs.php.net/bug.php?id=64075
17 * The bug should be somewhere in
18 * https://github.com/php/php-src/blob/master/ext/session/session.c#L2342
20 * Until this is fixed, we need to load the default session to load the data,
21 * export the upload progress information from there,
22 * and re-import after switching to our session.
24 * However, since https://github.com/phpmyadmin/phpmyadmin/commit/063a2d99
25 * we have deactivated this feature, so the corresponding code is now
26 * commented out.
