Nuno Diegues e9c2afec56 TUN-3948: Log error when retrying connection 2021-02-23 11:40:29 +00:00
Adam Chalmers a278753bbf TUN-3902: Add jitter to backoffhandler
Jitter is important to avoid every cloudflared in the world trying to
reconnect at t=1, 2, 4, etc. That could overwhelm the backend. But
if each cloudflared randomly waits for up to 2, then up to 4, then up
to 8 etc, then the retries get spread out evenly across time.

On average, wait times should be the same (e.g. instead of waiting for
exactly 1 second, cloudflared will wait betweeen 0 and 2 seconds).

This is the "Full Jitter" algorithm from https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/

Igor Postelnik 0b16a473da TUN-3869: Improve reliability of graceful shutdown.
- Don't rely on edge to close connection on graceful shutdown in h2mux, start muxer shutdown from cloudflared.
- Don't retry failed connections after graceful shutdown has started.
- After graceful shutdown channel is closed we stop waiting for retry timer and don't try to restart tunnel loop.
- Use readonly channel for graceful shutdown in functions that only consume the signal

Igor Postelnik a945518404 TUN-3811: Better error reporting on http2 connection termination. Registration errors from control loop are now propagated out of the connection server code. Unified error handling between h2mux and http2 connections so we log and retry errors the same way, regardless of underlying transport. 2021-01-28 10:38:30 -06:00
