This leaks less information + about when circuits have closed, and avoids unnecessary overhead + from renegotiating connections. Part of a fix for ticket 6799. + + - Instead of closing connections after they have been idle for a + fixed interval, randomly add up to 50% to each connection's + maximum timeout. This makes it harder to tell when the last + circuit closed by looking at when a connection closes. Part of a + fix for ticket 6799. + + - Base connection idleness tests on the actual time elapsed since + the connection last had circuits, not on the time when we last + added non-padding. This change also makes it harder for an + observer to tell when the last circuit closed by looking at when + a connection closes. Part of a fix for ticket 6799. + Incidentally fixes bug 12023; bugfix on 0.2.5.1-alpha. |
