First round of MQTT fixes (#3360) * mqtt: remove concept of connection timeout Just rely on the network stack to tell us when things have gone south. * mqtt: remove write-only mqtt_state.port field * mqtt: drop useless conditional * mqtt: decouple message sent flag from timer * mqtt: reconnect callback does not need to hang up The network stack has certainly done that for us at this point. Similarly, since we're about to call mqtt_socket_disconnected, don't bother unregistering the timer here, either. * mqtt: don't tick once per second Set the timer for the duration of the wait and cancel it on the other side. * mqtt: defer message queue destruction to _disconnect We're going to want to publish a disconnect message for real, so doing this in _close does no one any favors * mqtt: miscellaneous cleanups No functional change intended * mqtt: close() should send disconnect message for real This means waiting for _sent() to fire again before telling the network stack to disconnect. * mqtt: tidy connect and dns - Push the self-ref to after all allocations and error returns - Don't try to extract IPv4 from the domain string ourselves, let the resolver, since it can - Don't try to connect to localhost. That can't possibly work. * mqtt: common up some callback invocations * mqtt: don't retransmit messages on timeout There's no point in retransmitting messages on timeout; the network stack will be trying to do it for us anyway. * mqtt: remove unnecessary NULL udata checks * mqtt: hold strings in Lua, not C Eliminates a host of C-side allocations. While here, move the rest of the mqtt_connect_info structure out to its own thing, and pack some flags using a bitfield. * mqtt: mqtt_socket_on use lua_checkoption * mqtt: slightly augment debug messages These changes have made some debugging ever so slightly easier. 2021-01-05 11:07:09 +00:00
