#5525 closed enhancement (worksforme)

Need graceful shutdown for relays

On Windows, shutting down a To relay asks if you want to do a graceful shutdown, giving connected users time to find another relay. This should be possible in Linux too.

As it is, shutting down a Tor relay in Linux is an abrupt exit, anyone connected just has to wait for their connection to time out. On a busy node that is potentially thousand of people who know only that their web page partially loaded then hung.

I propose that a Close action be added to the existing Start and Stop (pardon my RedHat terminology) actions. This should delay a minute during which no new connections are accepted, then exit.

Send Tor a SIGINT. Does that not do what you want?

Works for me. I started a dummy relay, sent it a SIGINT (with "killall -INT tor"), and got:

Mar 29 14:12:23.000 [notice] Interrupt: we have stopped accepting new connections, and will shut down in 30 seconds. Interrupt again to exit now.

Closing this ticket for now. Please comment or reopen if you meant something different than what you get with SIGINT.

is this perhaps a vidalia bug?

The Tor package for Debian uses SIGINT:

        if start-stop-daemon --stop --signal INT --quiet --pidfile $TORPID --exec $DAEMON; then

As I understand it, Vidalia sends the equivalent control-port command when a user tells it to stop Tor.

Perhaps the original user is wanting the rpm to have this feature too? Given the red hat reference.
