Detailed Description

State kept for each MHD daemon. All connections are kept in two doubly-linked lists. The first one reflects the state of the connection in terms of what operations we are waiting for (read, write, locally blocked, cleanup) whereas the second is about its timeout state (default or custom).

struct MHD_Connection* MHD_Daemon::manual_timeout_head

Head of the XDLL of ALL connections with a non-default/custom timeout, unsorted. MHD will do a O(n) scan over this list to determine the current timeout.

struct MHD_Connection* MHD_Daemon::normal_timeout_head

Head of the XDLL of ALL connections with a default ('normal') timeout, sorted by timeout (earliest at the tail, most recently used connection at the head). MHD can just look at the tail of this list to determine the timeout for all of its elements; whenever there is an event of a connection, the connection is moved back to the tail of the list.

All connections by default start in this list; if a custom timeout that does not match 'connection_timeout' is set, they are moved to the 'manual_timeout_head'-XDLL.
