#531 closed defect (duplicate)

Transition from listener to specific listener disallowed

Description (last modified by nickm)

Coderman reported back in August that if you try to change from a listener on to a listener on a specific
address, Tor will often fail, because it doesn't close the old listener until the new listener is open (in order
to be undoable), but it can't open the new listener until the old one is closed.

See or-talk/or-dev thread, "Server node stalls on unsuccessful socks listener change."

It looks like we have two options:

1) Disallow the -> non change.
2) When transitioning from, accept that the transition will not be perfectly undoable.

00:41 < nickm> arma2: At your convenience, could you let me know which option

you like for bug 531?

00:45 < arma2> which option do you like?
00:46 < arma2> #2 would be better if it's not too hard
00:46 < arma2> since that seems like a change somebody might want to make some

day. for example, the people who found the bug.

00:46 < arma2> but if it *is* too hard, then #1 is better. :)

Closed #659 as a duplicate.

The real issue here is that we open new sockets before we close old ones, to make sure that the transition will work. But sometimes, our old sockets prevent us from opening the new ones, so we need to take a "leap of faith" and close the old ones to see if we can open the new ones.

Closing this as a duplicate of #17873, which is more comprehensive.
