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.
that all devices must be connected initially and that it's all memory
based so a crash wipes stored messages.) Accept messages for
forwarding when in the MISSING state, not just the ALLHERE state.
Store messages that can't be sent now, and send any that have
accumulated when a host reconnects. When a cref loses its last
connection, keep it around unless it has no messages stored (as will
be the case when a game ends.)
name. All new connections are stored together, and after each
connection an attempt is made to build one complete game with a host
and however many guests. All remaining devices are moved into a new
pending record in the same state, and the completed game is treated as
always. Seems to work, though nearly 20% of linux instances are
failing to connect the relay run from the new test script samename.sh.
Need to figure out why.
Also added logging of seed and connname to comms.c since games
launched together can no longer be certain to connect on the relay.
This allows the test script to identify joined games from their logs
and detect success or failure.
This checkin changes the relay protocol, so relay and clients will
both need to be upgraded.
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.
