Hello all, I'm trying to implement the setLocality in tabrmd. The comment says "Set the locality for the Connection object." I've found in the command_source_on_new_connection functions, it sets a callback for the istream in the Connection object. So I retrieved the ostream from the Connection, and tried to write sth. to trigger this callback. But nothing happens. I wonder is the thoughts right or there's sth. more need to do. Any comments or advice would be appreciated, thanks!
