void geoip_change_dirreq_state | ( | uint64_t | dirreq_id, |
dirreq_type_t | type, | ||
dirreq_state_t | new_state | ||

Change the state of the either direct or tunneled (see type) directory request with dirreq_id to new_state and possibly mark it as completed. If no entry can be found for the given key parts (e.g., if this is a directory request that we are not measuring, or one that was started in the previous measurement period), or if the state cannot be advanced to new_state, do nothing.

int geoip_get_client_history | ( | geoip_client_action_t | action, |
char ** | country_str, | ||
char ** | ipver_str | ||
) |
Store a newly allocated comma-separated string in *country_str containing entries for all the countries from which we've seen enough clients connect as a bridge, directory server, or entry guard. The entry format is cc=num where num is the number of IPs we've seen connecting from that country, and cc is a lowercased country code. *country_str is set to NULL if we're not ready to export per country data yet.
Store a newly allocated comma-separated string in ipver_str containing entries for clients connecting over IPv4 and IPv6. The format is family=num where num is the number of IPs we've seen connecting over that protocol family, and family is 'v4' or 'v6'.
Return 0 on success and -1 if we're missing geoip data.
unresolved requests are stored at index 0.
Definition at line 784 of file geoip_stats.c.
char * geoip_get_request_history | ( | void | ) |
Return a newly allocated string holding the per-country request history for v3 network statuses in a format suitable for an extra-info document, or NULL on failure.
Definition at line 879 of file geoip_stats.c.
char * geoip_get_transport_history | ( | void | ) |
Return the bridge-ip-transports string that should be inserted in our extra-info descriptor. Return NULL if the bridge-ip-transports line should be empty.
String hash table (name of transport) -> (number of users).
Smartlist that contains copies of the names of the transports that have been used.
We do the following steps to form the transport history string: a) Foreach client that uses a pluggable transport, we increase the times that transport was used by one. If the client did not use a transport, we increase the number of times someone connected without obfuscation. b) Foreach transport we observed, we write its transport history string and push it to string_chunks. So, for example, if we've seen 665 obfs2 clients, we write "obfs2=665". c) We concatenate string_chunks to form the final string.
