dbf9daf71b Fix problems reconnecting hosts where some but not all received the 
ALLHERE message and connName: change relay protocol so cookie is
included in RECONNECT message, and hostIDs are not assigned until
ALLHERE, and change host-to-game matching to use connName first but
fall back to cookie.  This fixes nearly all cases failing to reconnect
after relay goes down.

8be31357ad track per-cref lifetime and display it via http 2009-07-28 05:41:15 +00:00
ehouse
8284799abe Fix crashes resulting from deleting cref instances in one thread while 
another wanted to operate on them.  The root problem is that you can't
dispose of a mutex while somebody's blocking on it.  So now the
locking mutexes live inside the cref class.  When the lock owner
realizes the cref needs to die, it sets a flag and it's moved to a
recycled list.  A thread blocking on the mutex will then get it, but
checks the flag and releases it immediately if it's being recycled.
(Also improve the http interface a bit.)  With these changes I've run
31K (and counting) games against the relay without a crash or deadlock
(using sim_real.sh.)  The main problem that remains is that sometimes
two games using the same cookie wind up with two crefs (and so never
connect.)

25c4368231 Start adding ability to listen on multiple sockets and to dynamically

port.  Note that relay-related code in comms seems broken now, but is
without this checkin.

8f32f4f99a loads of changes: get settings from config file; remove sockets and 
kill crefs via state machine, and protect access to a cref so it can
die without another thread being in it; do timers via timeout to
poll() rather than interrupt (and integrate into state machine);
detect when all players are present and change state so new
connections on that cookie will get a new cref.

db6f6c258d move to using a formal table-driven state machine for each game (cref 
object).  While it makes things more complex at this point, it should
make it easier in the long run to add error handling, timeouts, etc.

50d8c1067b total rewrite. New protocol eliminates need to store and forward 
messages: clients connect, then messages are passthru only.  Add
control port.  Use stl map and vector to remove limit on number of
connections.  Also removed synchronization, which need to be re-added.
