* mqtt: expose "connfail" callback via :on() This makes it just like all the other callbacks in the module and is a revision of behavior called out in https://github.com/nodemcu/nodemcu-firmware/pull/2967 * mqtt: clarify when puback callback fires * mqtt: Don't reference stack buffers from the heap The confusingly-named "mqtt_connection_t" object is just a triple of - a serialized mqtt message pointer and length - a buffer pointer (to which the above can be written) - a message identifier The last of these must be passed around the mqtt state machine, but the first two are very local and the buffer is always sourced from the C stack. Unfortunately, because the entire structure is persisted in the heap, some callers assume that they can always use the structure without reinitialization (see mqtt_socket_close), which will trash the C stack. Sever the pairing between message id and local state, punt the local state entirely out of the heap, and rename things to be less confusing. |
