[feature suggestion] Need signal to totally switch to the new set of circuits

Currently there is the control command


which according to specification "switches to clean circuits, so new application requests don't share any circuits with old ones." It however doesn't affect the old connections, which still go through the old set of circuits.

There is the legitimate need to completely switch to the new set of circuits, with termination of all old connections.

I am suggesting to add the parameter to NEWNYM signal. It can be a string parameter, to keep it general and explicit. Syntax that will work like NEWNYM but will also terminate old connection could look like this:


The old syntax will assume this parameter to be empty, and will work like before.

On the user level, wherever they see the button "New Identity", they will either have another button next to it "New Identity (force-close old connections)", or the yes/no choice "force-close old connections" next to the original button.

My motivation: I had this question before myself, and now I saw somebody else asking it on tor-talk@: "Why my exit node doesn't change when I press 'New Identity' button?"

Doesn't sound too compelling. Just break the connections from the other side?

In general, how do users get the list of established through TOR connections on the running OS?

This might be a security / usability bug if users assume "New Identity" will change their exit. (I'm pretty sure this is what the New Identity documentation suggests.)

However, the "new exit for this circuit" in the latest TBB may resolve this issue.

Is this still an issue in Tor Browser 5.0?

I also think the tab isolation features in the recent Tor Browser designs should help this one a lot, for ordinary users.

What about the power users? I guess they could toggle disablenetwork on and off? I'm not super-excited to make it easy for people to add load to the Tor network when I don't understand their use case.

Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.
