prevents race conditions that are turning up when I'm running multiple
threads -- by allowing me to really not be running multiple threads.
Tested with the usual script.
(including seed so it's harder to spoof); respond to that by setting a
DEAD column in the db and flagging the device as gone. Notify any
connected device of the fact. Refuse to accept new connections to
that game. As already-connected devices reconnect, allow them to do
so but send a new status message that their game is dead. Not heavily
tested yet.
problem where, on PRX_HAS_MSGS path only, device reading socket gets
EOF early though logging here confirms additional bytes have been
written. Gross but effective.
ahead of processing data arrived on the same socket, with EnqueueKill
that adds to same queue from which data's taken. So if device dies
immediately after sending data there won't be a race between closing
the cref (if this is the last open socket) and handling the data. I'm
still dying with assert fails when running 100 games at once, but much
less frequently
game works to completion with both signing up as guests (no -s) with
one local and one remote player (identical commandlines.) Not yet
tested: if any signs up as a host, reconnecting rather than
connecting, etc. This is just a snapshot.
device id, to relay, one for each stored game that's communicating via
the relay. Relay parses out each relayID. Next relay can use these
to look up whether messages are available and reply with that, and
device can put up a notification.
connect first, guests second, with clear error messages if the order's
wrong. This seems to make it simpler for users to get a connection
right. Code holding multiple games worth of hosts and guests in a
cref is gone.
setting connName when all in a game are present. Second, have every
host include in connections a random number. That number is made part
of the connName and in general used to test whether a host belongs in
a particular game. Add this "seed" to web interface. Means new
versions for relay protocol and game stream format. Latter is handled
correctly so older games can be opened.
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.
to returing values for string keys so adding a new config doesn't mean
modifying that class. Then add new config for addr passed to bind so
relay can be run to accept http connections from remote machines.
change the set listened on. There's still some debugging to do but
nothing that worked before is broken. Also begin to accept unique
prefixes (e.g. g for get) for commands and attributes on the control
port. Note that relay-related code in comms seems broken now, but is
without this checkin.
lock. (This bug has always been there, but didn't matter before;
maybe pthreads changed.) Comment out self-spawning stuff until can
fix df-transfer problems. Other minor changes around logging.
send player counts, local and expected. Based on these the relay
accepts connections, declares the game full and ready for message
forwarding, and decides whether to accept a reconnect.
scheme where cookie is used only to connect, and is replaced for
reconnects by a relay-generated name that's supposed to be unique
across all games on all relays and includes a hostname read in from
config file; relay assign non-servers' hostIDs.
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.
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.
