Comment(by dcf):

 Replying to [comment:13 jct]:
 > 1) In '''onionoo-querying''' the internal structure for
 '''TorExitNodesSet''' was changed from a list to a dictionary. In this way
 the IP lookup 's time complexity has changed from O(n) to O(1)
 >
 > 2) In '''onionoo-querying-test''' was incremented the time in order to
 wait for the '''onionoo-querying''' daemon initialization, and thus avoid
 an error message of "connection refused".

 Note to self about what this program does. It periodically refreshes a
 local database of possible exits (IP addresses of relays whose exit policy
 is not `reject *:*`). It listens on localhost port 9003. On receiving a
 connection, it reads an IP address followed by a newline. If the IP
 address is a possible exit, it sends the string `"EXIT"`. If not, it sends
 `"OK_`''num''`"`, where ''num'' is the number of exits in the database.
 {{{
 $ ncat localhost 9003
 1.2.3.4
 OK_1074$ ncat localhost 9003
 jfsdkl
 OK_1074$ ncat localhost 9003

 EXIT
