[imp] Horde-RC2 & Oci8 SessionHandler Problems

[Sebastián Calero]

I make several tests and I think the problem comes with the use of the 'session_regenerate_id()' function with Oracle like session handler. 
I don't know this functions is executing but I always obtain the error:
[Thu Dec 3 12:10:00 2004] [error] PHP Warning:  save(): OCILobWrite: OCI_INVALID_HANDLE in /test/horde/lib/Horde/SessionHandler/oci8.php

'session_regenerate_id()' is called in Horde::getCleanSession(), if I modify this like:

    function getCleanSession()
    {
            @session_destroy();
            if (Util::extensionExists('posix')) {
                $new_session_id = md5(microtime() . posix_getpid());
            } else {
                $new_session_id = md5(uniqid(mt_rand(), true));
            }
            session_id($new_session_id);
            // Restart the session, including setting up the session
            // handler.
            Horde::setupSessionHandler();
            @session_start();
    }

All works fine with Oracle again.

I found this links related:

I send this post just in case it can help somebody...

Greetings and thanks.

	This looks like a really weird error in the PHP engine. We might trigger
	this, but we can't fix it. Try upgrading to PHP 4.3.9 or 4.3.10-RC1.

	Looking at the code this shouldn't happen, but I addded an extra check to
	the driver that might give an earlier error message. Try this patch:
