When reading large(ish) amounts of data, it is possible this data is read in multiple passes.
This means that
channelRead
could be called multiple times in succession, each time receiving only a chunk of the full data.To prevent trying to decode partial data, we must postpone the packet decoding until the channel read operation completes, which is we should do this in
channelReadComplete
instead.I have also inserted calls to forward operations to the next handler in the pipeline, as suggested by the documentation of the protocol functions.
