Try to tidy up a bit, move checks for if we are already calling/connected
Something I noticed when working on reconfigure support for the "Listen"
option is that we have some rather huge weaknesses in our multicasting
design. Right now if we change our Listen address, it's not really
possible for remote nodes to know whether they are still connected to
us, so they start connecting in response to our changed beacons. They
can't know that they already know about us until *after* the handshake
but this registers in the local client log as repeated Connect/Disconnects
even though the existing peerings never actually drop.

abd8b69979 send a switch message immediately when peering, and use OS-level TCP keep-alive (shouldn't matter right now, since we have application-level keep-alive that preempts it, but important later) 2018-12-14 18:15:35 -06:00

Make TCP read timeouts configurable.
This should be helpful on high-latency networks, like Tor or I2P.
Also gofmt.

91a374d698 rearrange tcp reading loop
according to documentation of io.Reader interface,
"Callers should always process the n > 0 bytes returned before considering the error err. Doing so correctly handles I/O errors that happen after reading some bytes and also both of the allowed EOF behaviors."

7695a3fcbf try using a simpler FIFO order for each backpressure buffer, since there are other mechanisms to penalize the flooding node, leads to better TCP throughput without affecting traffic between other nodes (does affect traffic in the same session, but there's hypothetically workarounds to that) 2018-06-24 20:20:07 -05:00
