- * The server list in InspIRCd is maintained as two structures
- * which hold the data in different ways. Most of the time, we
- * want to very quicky obtain three pieces of information:
- *
- * (1) The information on a server
- * (2) The information on the server we must send data through
- *     to actually REACH the server we're after
- * (3) Potentially, the child/parent objects of this server
- *
- * The InspIRCd spanning protocol provides easy access to these
- * by storing the data firstly in a recursive structure, where
- * each item references its parent item, and a dynamic list
- * of child items, and another structure which stores the items
- * hashed, linearly. This means that if we want to find a server
- * by name quickly, we can look it up in the hash, avoiding
- * any O(n) lookups. If however, during a split or sync, we want
- * to apply an operation to a server, and any of its child objects
- * we can resort to recursion to walk the tree structure.
- * Any socket can have one of five states at any one time.
- * The LISTENER state indicates a socket which is listening
- * for connections. It cannot receive data itself, only incoming
- * sockets.
- * The CONNECTING state indicates an outbound socket which is
- * waiting to be writeable.
- * The WAIT_AUTH_1 state indicates the socket is outbound and
- * has successfully connected, but has not yet sent and received
- * SERVER strings.
- * The WAIT_AUTH_2 state indicates that the socket is inbound
- * (allocated by a LISTENER) but has not yet sent and received
- * SERVER strings.
- * The CONNECTED state represents a fully authorized, fully
- * connected server.
