devid you tossed your relayID and reregistered. Which meant any
existing messages meant for your relayID were orphaned, and any open
games didn't know who they belonged to until you reconnected to them
with your new relayID. So: modify the UDP protocol (though not on
Android yet) to include both relayID and devid with registration, with
one or the other an empty string if not present or not changed from
earlier. I can't fix existing clients that are dropping their
relayIDs, but when one does a re-connect without a relayID I can look
it up from the existing game record, then reuse it rather than issue a
new one. Better than nothing -- and that protocol will be obsolete
soon anyway.
and their slots are empty or have been reassigned: basically we check
if a device goes where it expects, and if not treat it as a new
connection rather than a reconnect, meaning its hostid may change.
Existing device code seems ok with that -- and at any rate I don't
think ACKs get dropped much in the wild.
once UDP sockets and/or per-device (not per-game) connections come
along. Lots of changes, most not involving code flow but a couple
that did. So far two gtk games can connect and exchange moves.
Haven't tested reconnection or store-and-forward.
which they're communicated to the device. Device is expected to have
a platform-specific notion of ID which the relay stores in a new
devices table and indexes with a 32-bit number which is returned to
the device -- which is encouraged but not required to use it in lieu
of the longer ID in future communications. Modify linux client and
test script to use the relay-supplied id. Some of this is commented
out for now.
of which is TBD). When a new-version client connects, store the value
it's passed. At first this will let me track how quickly people
upgrade. Later I can use it to let different clients have different
formats to their messages e.g. to proxy.
reconnect. I was putting both (i.e. the same device twice) in the
same game. Now I detect this based on the seed being duplicated and
treat the device as having failed to ACK then proceed with the CONNECT
as if it were new. Tested pretty heavily but only with two-device
games.
(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.
connName/hid pair. This works around a problem where a device,
continuing to connect and send all pending messages for another device
that is not connecting, winds up with hundreds of identical messages
stored.
recycling of crefs between when devices in a game connect. This plus
movement of messages into the DB will re-enable games played without
the two devices ever being connected at the same time.
threads can't share the same db connection. So synchronize all
queries. Multiple threads *can* access the db concurrently as long as
each has its own connection, so I could add connections to the tpool
threads. But this will probably be performant enough for the first
10K simultaneous users. :-)
ALLCOND until it's time to kill the cref. When one device connects
and leaves the cref is recycled, so when a new device joins and is
assigned the same game and a new cref is initialized the number of
players already registered must be set from the db entry; do that.
