Ticket #1483986 (Bugs) Session expires

Further to my previous email:

My suspicion is that the bug is in RoundCube's custom session handling code. As I poke in program/include/session.inc I note that Roundcube installs custom PHP session handlers here:

// set custom functions for PHP session management
session_set_save_handler('sess_open', 'sess_close', 'sess_read', 'sess_write','sess_destroy', 'sess_gc');

Specifically, my suspicion is that the sess_gc() function is deleting sessions incorrectly (ie. prematurely).

QUESTIONS:

1. Why the custom session handling code? Was it for scaling with multiple servers? If I has only one server (a simple environment), what does storing the sessions in a database accomplish?

2. If I disabled the garbage collection code (sess_gc) and allowed the stale sessions to collect rather than have them deleted, what would the impact of that be other than disk space in the database? I might manually hoof them all once a week.

3. If the answer to the final part of #1 is "not a lot", what would happen if I did not install the custom session handlers and just let PHP's own code do it?

I might be all wet and not understanding at all what the code is supposed to do. If so, please forgive me. However, I have users who really want to use RoundCube but the session expiry bug is killing them. I need a tactical solution until the real issue is addressed.

Thanks!
