2. Added a command to the control protocol to purge any cached state relating to a specified hidden service. This command can be used before trying to connect to the service to force Tor to download a fresh descriptor. It's a more fine-grained alternative to SIGNAL NEWNYM, which purges all cached descriptors and also discards circuits.
I've only done small-scale testing of these patches so far. If they seems like they might be useful I'll create a trac ticket to merge them.
I've added a link to this thread to the below ticket. Somewhere therein I and Qingping were describing need and syntax to flush/fetch hidden service descriptors via control. For which your HS descriptor purge may be a useful component. If it is able to flush both single specified, or all, HS desc's that could be good semantic so as not to disturb other state. Thanks. # Allow controllers to retrieve HS descriptors from Tor https://trac.torproject.org/projects/tor/ticket/3521
