Example 18 with GoAwayFrame

use of com.webpieces.http2.api.dto.lowlevel.GoAwayFrame in project webpieces by deanhiller.

the class TestS5x1StreamStates method testSection5_1_1TooLowStreamIdAfterHighStreamId.

/**
 * The identifier of a newly established stream MUST be numerically
 * greater than all streams that the initiating endpoint has opened
 * or reserved. This governs streams that are opened using a HEADERS
 * frame and streams that are reserved using PUSH_PROMISE. An endpoint
 * that receives an unexpected stream identifier MUST respond with
 * a connection error (Section 5.4.1) of type PROTOCOL_ERROR.
 *
 * This is in conflict with another part of the spec!!!!! and so we pretend
 * the stream is closed(as in all likely hood, the stream was closed)!!!
 * and do not shutdown the whole connection for a case like this.
 *
 * The part it is in conflict with is closed state and receiving messages
 * in closed state.  The only way to resolve conflict would be to KEEP around
 * state that a connection is closed.  SORRY, the connection is closed so we
 * clean up all memory!!!
