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.
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
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.
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.
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.
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.
