Detailed Description

Legacy Server code managing a connection to a client.

NP: presents AsyncJob API but does not operate autonomously as a Job. So Must() is not safe to use.

Multiple requests (up to pipeline_prefetch) can be pipelined. This object is responsible for managing which one is currently being fulfilled and what happens to the queue if the current one causes the client connection to be closed early.

Act as a manager for the client connection and passes data in buffer to a Parser relevant to the state (message headers vs body) that is being processed.

Performs HTTP message processing to kick off the actual HTTP request handling objects (Http::Stream, ClientHttpRequest, HttpRequest).

Performs SSL-Bump processing for switching between HTTP and HTTPS protocols.

To terminate a ConnStateData close() the client Comm::Connection it is managing, or for graceful half-close use the stopReceiving() or stopSending() methods.

◆ kick()

void ConnStateData::kick ( )
We are done with the response, and we are either still receiving request body (early response!) or have already stopped receiving anything.

If we are still receiving, then clientParseRequest() below will fail. (XXX: but then we will call readNextRequest() which may succeed and execute a smuggled request as we are not done with the current request).

If we stopped because we got everything, then try the next request.

If we stopped receiving because of an error, then close now to avoid getting stuck and to prevent accidental request smuggling.

Attempt to parse a request from the request buffer. If we've been fed a pipelined request it may already be in our read buffer.
This needs to fall through - if we're unlucky and parse the last request from our read buffer we may never re-register for another client read.
Either we need to kick-start another read or, if we have a half-closed connection, kill it after the last request. This saves waiting for half-closed connections to finished being half-closed AND then, sometimes, spending "Timeout" time in the keepalive "Waiting for next request" state.
At this point we either have a parsed request (which we've kicked off the processing for) or not. If we have a deferred request (parsed but deferred for pipeling processing reasons) then look at processing it. If not, simply kickstart another read.
