# WebTransportSessionProxy
|
||||
|
||||
WebTransportSessionProxy is introduced to enable the creation of a Http3WebTransportSession and coordination of actions that are performed on the main thread and on the socket thread.
|
||||
|
||||
WebTransportSessionProxy can be in different states and the following diagram depicts the transition between the states. “MT” and “ST” mean: the action is happening on the main and socket thread. More details about this class can be found in [WebTransportSessionProxy.h](https://searchfox.org/mozilla-central/source/netwerk/protocol/webtransport/WebTransportSessionProxy.h).

* WebTransport
|
||||
*
|
||||
* Http3Session and the underlying neqo code support multiplexing of multiple
|
||||
* WebTransport and multiplexing WebTransport sessions with regular HTTP
|
||||
* traffic. Whether WebTransport sessions are polled, will be controlled by the
|
||||
* nsHttpConnectionMgr.
|
||||
*
|
||||
* WebTransport support is negotiated using HTTP/3 setting. Before the settings
|
||||
* are available all WebTransport transactions are queued in
|
||||
* mWaitingForWebTransportNegotiation. The information on whether WebTransport
|
||||
* is supported is received via an HTTP/3 event. The event is
|
||||
* Http3Event::Tag::WebTransport with the value
|
||||
* WebTransportEventExternal::Tag::Negotiated that can be true or false. If
|
||||
* the WebTransport feature has been negotiated, queued transactions will be
|
||||
* activated otherwise they will be canceled(i.e. WebTransportNegotiationDone).
|
||||
*
|
||||
* The lifetime of a WebTransport session
|
||||
*
|
||||
* A WebTransport lifetime consists of 2 parts:
|
||||
* - WebTransport session setup
|
||||
* - WebTransport session active time
|
||||
*
|
||||
* WebTransport session setup:
|
||||
* A WebTransport session uses a regular HTTP request for negotiation.
|
||||
* Therefore when a new WebTransport is started a nsHttpChannel and the
|
||||
* corresponding nsHttpTransaction are created. The nsHttpTransaction is
|
||||
* dispatched to a Http3Session and after the
|
||||
* WebTransportEventExternal::Tag::Negotiated event it behaves almost the same
|
||||
* as a regular transaction, e.g. it is added to mStreamTransactionHash and
|
||||
* mStreamIdHash. For activating the session NeqoHttp3Conn::CreateWebTransport
|
||||
* is called instead of NeqoHttp3Conn::Fetch(this is called for the regular
|
||||
* HTTP requests). In this phase, the WebTransport session is canceled in the
|
||||
* same way a regular request is canceled, by canceling the corresponding
|
||||
* nsHttpChannel. If HTTP/3 connection is closed in this phase the
|
||||
* corresponding nsHttpTransaction is canceled and this may cause the
|
||||
* transaction to be restarted (this is the existing restart logic) or the
|
||||
* error is propagated to the nsHttpChannel and its listener(via OnStartRequest
|
||||
* and OnStopRequest as the regular HTTP request).
|
||||
* The phase ends when a connection breaks or when the event
|
||||
* Http3Event::Tag::WebTransport with the value
|
||||
* WebTransportEventExternal::Tag::Session is received. The parameter
|
||||
* aData(from NeqoHttp3Conn::GetEvent) contain the HTTP head of the response.
|
||||
* The headers may be:
|
||||
* - failed code, i.e. anything except 200. In this case, the nsHttpTransaction
|
||||
* behaves the same as a normal HTTP request and the nsHttpChannel listener
|
||||
* will be informed via OnStartRequest and OnStopRequest calls.
|
||||
* - success code, i.e. 200. The code will be propagated to the
|
||||
* nsHttpTransaction. The transaction will parse the header and call
|
||||
* Http3Session::GetWebTransportSession. The function transfers WebTransport
|
||||
* session into the next phase:
|
||||
* - Removes nsHttpTransaction from mStreamTransactionHash.
|
||||
* - Adds the stream to mWebTransportSessions
|
||||
* - The nsHttpTransaction supplies Http3WebTransportSession to the
|
||||
* WebTransportSessionProxy and vice versa.
|
||||
* TODO remove this circular referencing.
|
||||
*
|
||||
* WebTransport session active time:
|
||||
* During this phase the following actions are possible:
|
||||
* - Cancelling a WebTransport session by the application:
|
||||
* The application calls Http3WebTransportSession::CloseSession. This
|
||||
* transfers Http3WebTransportSession into the CLOSE_PENDING state and calls
|
||||

||||
* - ACTIVE: during the OnStopRequest call if the WebTransport has not been
|
||||
* canceled or failed for other reason, e.g. a browser shutdown or content
|
||||
* blocking policies.
|
||||
* - SESSION_CLOSE_PENDING: if the WebTransport has been canceled via an API
|
||||
* call or content blocking policies. (the main thread initiated close).
|
||||
* - CLOSE_CALLBACK_PENDING: if Http3WebTransportSession has been canceled
|
||||
* due to a shutdown or a server closing a session. (the socket thread
|
||||
* initiated close).
|
||||
*
|
||||
* - ACTIVE: In this state the session is negotiated and ready to use. This
|
||||
* state can transfer into:
|
||||
* - SESSION_CLOSE_PENDING: if the WebTransport has been canceled via an API
|
||||
* call(nsIWebTransport::closeSession) or content blocking policies. (the
|
||||
* main thread initiated close).
|
||||
* - CLOSE_CALLBACK_PENDING: if Http3WebTransportSession has been canceled
|
||||
* due to a shutdown or a server closing a session. (the socket thread
|
||||
* initiated close).
|
||||
*
|
||||
* - CLOSE_CALLBACK_PENDING: This is the socket thread initiated close. In this
|
||||
* state, the Http3WebTransportSession has been closed and a
|
||||
* CallOnSessionClosed call is dispatched to the main thread to call the
|
||||
* appropriate listener.
|
||||
*
|
||||
* - SESSION_CLOSE_PENDING: This is the main thread initiated close. In this
|
||||
* state, the WebTransport has been closed via an API call
|
||||
* (nsIWebTransport::closeSession) and a CloseSessionInternal call is
|
||||
* dispatched to the socket thread to close the appropriate
|
||||
* Http3WebTransportSession.
|
||||
*
|
||||
* - DONE: everything has been cleaned up on both threads.
|
||||
*
|
||||
*
|
||||
* AsyncConnect creates mChannel on the main thread. Redirect callbacks are also
|
||||
* performed on the main thread (mRedirectChannel set and access only on the
|
||||
* main thread). Before this point, there are no activities on the socket thread
|
||||
* and Http3WebTransportSession is nullptr. mChannel is going to create a
|
||||
* nsHttpTransaction. The transaction will be dispatched on a nsAHttpConnection,
|
||||
* i.e. currently only the HTTP/3 version is implemented, therefore this will be
|
||||
* a HttpConnectionUDP and a Http3Session. The Http3Session creates a
|
||||
* Http3WebTransportSession. Until a response is received
|
||||
* Http3WebTransportSession is only accessed by Http3Session. During parsing of
|
||||
* a successful received from a server on the socket thread,
|
||||
* WebTransportSessionProxy::mWebTransportSession will take a reference to
|
||||
* Http3WebTransportSession and mState will be set to NEGOTIATING_SUCCEEDED.
|
||||
* From now on WebTransportSessionProxy is responsible for closing
|
||||
* Http3WebTransportSession if the closing of the session is initiated on the
|
||||
* main thread. OnStartRequest and OnStopRequest will be called on the main
|
||||
* thread. The session negotiation can have 2 outcomes:
|
||||
* - If both calls, i.e. OnStartRequest an OnStopRequest, indicate that the
|
||||
* request has succeeded and mState is NEGOTIATING_SUCCEEDED, the
|
||||
* mListener->OnSessionReady will be called during OnStopRequest.
|
||||
* - Otherwise, mListener->OnSessionClosed will be called, the state transferred
|
||||
* into SESSION_CLOSE_PENDING, and CloseSessionInternal will be dispatched to
|
||||
* the socket thread.
|
||||
*
|
||||
* CloseSession is called on the main thread. If the session is already closed
|
||||
* it returns an error. If the session is in state NEGOTIATING or
|
||||
* NEGOTIATING_SUCCEEDED mChannel will be canceled. If the session is in state
|
||||
* NEGOTIATING_SUCCEEDED or ACTIVE the state transferred into
|
||||
* SESSION_CLOSE_PENDING, and CloseSessionInternal will be dispatched to the
|
||||
* socket thread
|
||||
*
|
||||
* OnSessionReadyInternal is called on the socket thread. If mState is
|
||||
* NEGOTIATING the state will be set to NEGOTIATING_SUCCEEDED and mWebTransport
|
||||
* will be set to the newly negotiated Http3WebTransportSession. If mState is
|
||||
* DONE, the Http3WebTransportSession will be close.
|
||||
*
|
||||
* OnSessionClosed is called on the socket thread. mState will be set to
|
||||
* CLOSE_CALLBACK_PENDING and CallOnSessionClosed will be dispatched to the main
|
||||
* thread.
|
||||
*
|
||||
* mWebTransport is set during states NEGOTIATING_SUCCEEDED, ACTIVE and
|
||||
* SESSION_CLOSE_PENDING.
