TODO someday.. whenever we start using person without user. there's a thought in my head that says it may become useful to split this file some more so one can implement "caches" for remote psyc people that are *not* linked and represented by this server. just one out of many possible approaches to solve the problem of resolving nicknames into remote users. the other is to keep nick-to-uni/unl data structures in each object. but even basic information like uni and unl is already more than just one string, so it's prolly worth an object to handle it.. */ // local debug messages - turn them on by using psyclpc -DDperson= #ifdef Dperson # undef DEBUG # define DEBUG Dperson #endif #include #include #include #include #include #include #include #if __EFUN_DEFINED__(tls_query_connection_info) # include #endif inherit NET_PATH "group/master"; inherit NET_PATH "lastlog"; volatile mixed place; volatile mapping places; volatile int leaving, greeting; volatile string lastmc; volatile string nonce; // this flag seems to indicate that any announce() has gone out // not sure if ONLINE would do as well..
