### Config Serving

Config serving is the layer that actually accepts proxy clients, connected over bidirectional gRPC streams, and serve them the required configuration.

We will have two triggers for sending config - requests and pushes.

#### Requests

	// special value -1 means no explicit seeding.
	if seed != -1 {
		rand.Seed(seed)
	}
	return rand.Intn(max-min) + min
}

// Randomizes the order of bytes in the byte array
// using Knuth Fisher-Yates shuffle algorithm.
func randomizeBytes(s []byte, seed int64) []byte {
	// special value -1 means no explicit seeding.
	if seed != -1 {
		rand.Seed(seed)
	}
	n := len(s)

/**
 * This class simplifies communication for protocols that support
 * multiplexing requests. It encapsulates a stream and some protocol
 * knowledge (provided by a concrete subclass) so that connecting,
 * disconnecting, sending, and receiving can be syncronized
 * properly. Apparatus is provided to send and receive requests
 * concurrently.

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

## More motivation

Check this function, it already has type hints:

		switch strings.TrimSpace(p) {
		case dotdotComponent:
			return true
		case dotComponent:
			return true
		}
	}
	return false
}

// Check if client is sending a malicious request.
func hasMultipleAuth(r *http.Request) bool {
	authTypeCount := 0
	for _, hasValidAuth := range []func(*http.Request) bool{
		isRequestSignatureV2, isRequestPresignedSignatureV2,

you had a client that was sending an invalid Content-Type or Accept header to
the API, in 1.2 you will either receive a 415 or 406 error.
The only client
this is known to affect is curl when you use -d with JSON but don't set a
content type, helpfully sends "application/x-www-urlencoded", which is not
correct.
Other client authors should double check that you are sending proper

            try {
                CommonServerMessageBlockResponse resp = thisReq.getResponse();
                if ( log.isTraceEnabled() ) {
                    log.trace("Sending " + thisReq);
                }
                resp = super.sendrecv(curHead, resp, params);

                if ( !checkStatus(curHead, resp) ) {
                    if ( log.isDebugEnabled() ) {

                acquiredLock, this, previousDeadlockException.getConflictingStackTrace());
        policy.handlePotentialDeadlock(exception);
        return;
      }
      // Otherwise, it's the first time seeing this lock relationship. Look for
      // a path from the acquiredLock to this.
      Set<LockGraphNode> seen = Sets.newIdentityHashSet();
      ExampleStackTrace path = acquiredLock.findPathTo(this, seen);
