-libnghttp2_asio: High level HTTP/2 C++ library
-----------------------------------------------
-
-libnghttp2_asio is C++ library built on top of libnghttp2 and provides
-high level abstraction API to build HTTP/2 applications.  It depends
-on the Boost::ASIO library and OpenSSL.  Currently libnghttp2_asio
-provides both client and server APIs.
-
-libnghttp2_asio is not built by default.  Use the ``--enable-asio-lib``
-configure flag to build libnghttp2_asio.  The required Boost libraries
-are:
-
-* Boost::Asio
-* Boost::System
-* Boost::Thread
-
-The server API is designed to build an HTTP/2 server very easily to utilize
-C++14 anonymous functions and closures.  The bare minimum example of
-an HTTP/2 server looks like this:
-
-.. code-block:: cpp
-
-    #include <iostream>
-
-    #include <nghttp2/asio_http2_server.h>
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::server;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      http2 server;
-
-      server.handle("/", [](const request &req, const response &res) {
-        res.write_head(200);
-        res.end("hello, world\n");
-      });
-
-      if (server.listen_and_serve(ec, "localhost", "3000")) {
-        std::cerr << "error: " << ec.message() << std::endl;
-      }
-    }
-
-Here is sample code to use the client API:
-
-.. code-block:: cpp
-
-    #include <iostream>
-
-    #include <nghttp2/asio_http2_client.h>
-
-    using boost::asio::ip::tcp;
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::client;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      boost::asio::io_service io_service;
-
-      // connect to localhost:3000
-      session sess(io_service, "localhost", "3000");
-
-      sess.on_connect([&sess](tcp::resolver::iterator endpoint_it) {
-        boost::system::error_code ec;
-
-        auto req = sess.submit(ec, "GET", "http://localhost:3000/");
-
-        req->on_response([](const response &res) {
-          // print status code and response header fields.
-          std::cerr << "HTTP/2 " << res.status_code() << std::endl;

-
-Python bindings
----------------
-
-The ``python`` directory contains nghttp2 Python bindings.  The
-bindings currently provide HPACK compressor and decompressor classes
-and an HTTP/2 server.
-
-The extension module is called ``nghttp2``.
-
-``make`` will build the bindings and target Python version is
-determined by the ``configure`` script.  If the detected Python version is not
-what you expect, specify a path to Python executable in a ``PYTHON``
-variable as an argument to configure script (e.g., ``./configure
-PYTHON=/usr/bin/python3.8``).
-
-The following example code illustrates basic usage of the HPACK compressor
-and decompressor in Python:
-
-.. code-block:: python
-
-    import binascii
-    import nghttp2
-
-    deflater = nghttp2.HDDeflater()
-    inflater = nghttp2.HDInflater()
-
-    data = deflater.deflate([(b'foo', b'bar'),
-                             (b'baz', b'buz')])
-    print(binascii.b2a_hex(data))
-
-    hdrs = inflater.inflate(data)
-    print(hdrs)
-
-The ``nghttp2.HTTP2Server`` class builds on top of the asyncio event
-loop.  On construction, *RequestHandlerClass* must be given, which
-must be a subclass of ``nghttp2.BaseRequestHandler`` class.
-
-The ``BaseRequestHandler`` class is used to handle the HTTP/2 stream.
-By default, it does nothing.  It must be subclassed to handle each
-event callback method.
-
-The first callback method invoked is ``on_headers()``.  It is called
-when HEADERS frame, which includes the request header fields, has arrived.
-
-If the request has a request body, ``on_data(data)`` is invoked for each
-chunk of received data.
-
-Once the entire request is received, ``on_request_done()`` is invoked.
-
-When the stream is closed, ``on_close(error_code)`` is called.
-
-The application can send a response using ``send_response()`` method.
-It can be used in ``on_headers()``, ``on_data()`` or
-``on_request_done()``.
-
-The application can push resources using the ``push()`` method.  It must be
-used before the ``send_response()`` call.
-
-The following instance variables are available:
-
-client_address
-    Contains a tuple of the form (host, port) referring to the
-    client's address.
-
-stream_id
-    Stream ID of this stream.
-
-scheme
-    Scheme of the request URI.  This is a value of :scheme header
-    field.
-
-method
-    Method of this stream.  This is a value of :method header field.
-
-host
-    This is a value of :authority or host header field.
-
-path
-    This is a value of :path header field.
-
-The following example illustrates the HTTP2Server and
-BaseRequestHandler usage:
-
-.. code-block:: python
-
-    #!/usr/bin/env python3
-
-    import io, ssl
-    import nghttp2
-
-    class Handler(nghttp2.BaseRequestHandler):
-
-        def on_headers(self):
-            self.push(path='/css/bootstrap.css',

+Stream priorities
+-----------------
+
+By default, the stream prioritization scheme described in :rfc:`7540`
+is used.  This scheme has been formally deprecated by :rfc:`9113`.  In
+order to disable it, send
+:enum:`nghttp2_settings_id.NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES` of
+value of 1 via `nghttp2_submit_settings()`.  This settings ID is
+defined by :rfc:`9218`.  The sender of this settings value disables
+RFC 7540 priorities, and instead it enables RFC 9218 Extensible
+Prioritization Scheme.  This new prioritization scheme has 2 methods
+to convey the stream priorities to a remote endpoint: Priority header
+field and PRIORITY_UPDATE frame.  nghttp2 supports both methods.  In
+order to receive and process PRIORITY_UPDATE frame, server has to call
+``nghttp2_option_set_builtin_recv_extension_type(option,
+NGHTTP2_PRIORITY_UPDATE)`` (see the above section), and pass the
+option to `nghttp2_session_server_new2()` or
+`nghttp2_session_server_new3()` to create a server session.  Client
+can send Priority header field via `nghttp2_submit_request()`.  It can
+also send PRIORITY_UPDATE frame via
+`nghttp2_submit_priority_update()`.  Server processes Priority header
+field in a request header field and updates the stream priority unless
+HTTP messaging rule enforcement is disabled (see
+`nghttp2_option_set_no_http_messaging()`).
+
+For the purpose of smooth migration from RFC 7540 priorities, client
+is advised to send
+:enum:`nghttp2_settings_id.NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES` of
+value of 1.  Until it receives the first server SETTINGS frame, it can
+send both RFC 7540 and RFC 9128 priority signals.  If client receives
+SETTINGS_NO_RFC7540_PRIORITIES of value of 0, or it is omitted ,
+client stops sending PRIORITY_UPDATE frame.  Priority header field
+will be sent in anyway since it is an end-to-end signal.  If
+SETTINGS_NO_RFC7540_PRIORITIES of value of 1 is received, client stops
+sending RFC 7540 priority signals.  This is the advice described in
+:rfc:`9218#section-2.1.1`.
+
+Server has an optional mechanism to fallback to RFC 7540 priorities.
+By default, if server sends SETTINGS_NO_RFC7540_PRIORITIES of value of
+1, it completely disables RFC 7540 priorities and no fallback.  By
+setting nonzero value to
+`nghttp2_option_set_server_fallback_rfc7540_priorities()`, server
+falls back to RFC 7540 priorities if it sends
+SETTINGS_NO_RFC7540_PRIORITIES value of value of 1, and client omits
+SETTINGS_NO_RFC7540_PRIORITIES in its SETTINGS frame.

-libnghttp2_asio: High level HTTP/2 C++ library
-==============================================
-
-libnghttp2_asio is C++ library built on top of libnghttp2 and provides
-high level abstraction API to build HTTP/2 applications.  It depends
-on Boost::ASIO library and OpenSSL.  Currently libnghttp2_asio
-provides server and client side API.
-
-libnghttp2_asio is not built by default.  Use ``--enable-asio-lib``
-configure flag to build libnghttp2_asio.  The required Boost libraries
-are:
-
-* Boost::Asio
-* Boost::System
-* Boost::Thread
-
-We have 3 header files for this library:
-
-* :doc:`asio_http2_server.h`
-* :doc:`asio_http2_client.h`
-* :doc:`asio_http2.h`
-
-asio_http2.h is included from the other two files.
-
-To build a program with libnghttp2_asio, link to the following
-libraries::
-
-    -lnghttp2_asio -lboost_system
-
-If ``boost::asio::ssl`` is used in application code, OpenSSL is also
-required in link line::
-
-    -lnghttp2_asio -lboost_system -lssl -lcrypto
-
-Server API
-----------
-
-To use server API, first include following header file:
-
-.. code-block:: cpp
-
-    #include <nghttp2/asio_http2_server.h>
-
-Also take a look at that header file :doc:`asio_http2_server.h`.
-
-Server API is designed to build HTTP/2 server very easily to utilize
-C++11 anonymous function and closure.  The bare minimum example of
-HTTP/2 server looks like this:
-
-.. code-block:: cpp
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::server;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      http2 server;
-
-      server.handle("/", [](const request &req, const response &res) {
-        res.write_head(200);
-        res.end("hello, world\n");
-      });
-
-      if (server.listen_and_serve(ec, "localhost", "3000")) {
-        std::cerr << "error: " << ec.message() << std::endl;
-      }
-    }
-
-First we instantiate ``nghttp2::asio_http2::server::http2`` object.
-``nghttp2::asio_http2::server::http2::handle`` function registers
-pattern and its handler function.  In this example, we register "/" as
-pattern, which matches all requests.  Then call
-``nghttp2::asio_http2::server::http2::listen_and_serve`` function with
-address and port to listen to.
-
-The ``req`` and ``res`` represent HTTP request and response
-respectively.  ``nghttp2::asio_http2_::server::response::write_head``
-constructs HTTP response header fields.  The first argument is HTTP
-status code, in the above example, which is 200.  The second argument,
-which is omitted in the above example, is additional header fields to
-send.
-
-``nghttp2::asio_http2::server::response::end`` sends response body.
-In the above example, we send string "hello, world".
-
-The life time of req and res object ends after the callback set by
-``nghttp2::asio_http2::server::response::on_close`` function.
-Application must not use those objects after this call.
-
-Serving static files and enabling SSL/TLS
-+++++++++++++++++++++++++++++++++++++++++
-
-In this example, we serve a couple of static files and also enable
-SSL/TLS.
-
-.. code-block:: cpp
-
-    #include <nghttp2/asio_http2_server.h>
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::server;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      boost::asio::ssl::context tls(boost::asio::ssl::context::sslv23);
-
-      tls.use_private_key_file("server.key", boost::asio::ssl::context::pem);
-      tls.use_certificate_chain_file("server.crt");
-
-      configure_tls_context_easy(ec, tls);
-
-      http2 server;
-
-      server.handle("/index.html", [](const request &req, const response &res) {
-        res.write_head(200);
-        res.end(file_generator("index.html"));
-      });
-
-      if (server.listen_and_serve(ec, tls, "localhost", "3000")) {
-        std::cerr << "error: " << ec.message() << std::endl;
-      }
-    }
-
-We first create ``boost::asio::ssl::context`` object and set path to
-private key file and certificate file.
-``nghttp2::asio_http2::server::configure_tls_context_easy`` function
-configures SSL/TLS context object for HTTP/2 server use, including NPN
-callbacks.
-
-In the above example, if request path is "/index.html", we serve
-index.html file in the current working directory.
-``nghttp2::asio_http2::server::response::end`` has overload to take
-function of type ``nghttp2::asio_http2::generator_cb`` and application
-pass its implementation to generate response body.  For the
-convenience, libnghttp2_asio library provides
-``nghttp2::asio_http2::file_generator`` function to generate function
-to server static file.  If other resource is requested, server
-automatically responds with 404 status code.
-
-Server push
-+++++++++++
-
-Server push is also supported.
-
-.. code-block:: cpp
-
-    #include <nghttp2/asio_http2_server.h>
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::server;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      boost::asio::ssl::context tls(boost::asio::ssl::context::sslv23);
-
-      tls.use_private_key_file("server.key", boost::asio::ssl::context::pem);
-      tls.use_certificate_chain_file("server.crt");
-
-      configure_tls_context_easy(ec, tls);
-
-      http2 server;
-
-      std::string style_css = "h1 { color: green; }";
-
-      server.handle("/", [&style_css](const request &req, const response &res) {
-        boost::system::error_code ec;
-        auto push = res.push(ec, "GET", "/style.css");
-        push->write_head(200);
-        push->end(style_css);
-
-        res.write_head(200);
-        res.end(R"(
-    <!DOCTYPE html><html lang="en">
-    <title>HTTP/2 FTW</title><body>
-    <link href="/style.css" rel="stylesheet" type="text/css">
-    <h1>This should be green</h1>
-    </body></html>
-    )");
-      });
-
-      server.handle("/style.css",
-                    [&style_css](const request &req, const response &res) {
-        res.write_head(200);
-        res.end(style_css);
-      });
-
-      if (server.listen_and_serve(ec, tls, "localhost", "3000")) {
-        std::cerr << "error: " << ec.message() << std::endl;
-      }
-    }
-
-When client requested any resource other than "/style.css", we push
-"/style.css".  To push resource, call
-``nghttp2::asio_http2::server::response::push`` function with desired
-method and path.  It returns another response object and use its
-functions to send push response.
-
-Enable multi-threading
-++++++++++++++++++++++
-
-Enabling multi-threading is very easy.  Just call
-``nghttp2::asio_http2::server::http2::num_threads`` function with the
-desired number of threads:
-
-.. code-block:: cpp
-
-    http2 server;
-
-    // Use 4 native threads
-    server.num_threads(4);
-
-Client API
-----------
-
-To use client API, first include following header file:
-
-.. code-block:: cpp
-
-    #include <nghttp2/asio_http2_client.h>
-
-Also take a look at that header file :doc:`asio_http2_client.h`.
-
-Here is the sample client code to access HTTP/2 server and print out
-response header fields and response body to the console screen:
-
-.. code-block:: cpp
-
-    #include <iostream>
-
-    #include <nghttp2/asio_http2_client.h>
-
-    using boost::asio::ip::tcp;
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::client;
-
-    int main(int argc, char *argv[]) {
-      boost::system::error_code ec;
-      boost::asio::io_service io_service;
-
-      // connect to localhost:3000
-      session sess(io_service, "localhost", "3000");
-
-      sess.on_connect([&sess](tcp::resolver::iterator endpoint_it) {
-	boost::system::error_code ec;
-
-	auto req = sess.submit(ec, "GET", "http://localhost:3000/");
-
-	req->on_response([](const response &res) {
-	  // print status code and response header fields.
-	  std::cerr << "HTTP/2 " << res.status_code() << std::endl;
-	  for (auto &kv : res.header()) {
-	    std::cerr << kv.first << ": " << kv.second.value << "\n";
-	  }
-	  std::cerr << std::endl;
-
-	  res.on_data([](const uint8_t *data, std::size_t len) {
-	    std::cerr.write(reinterpret_cast<const char *>(data), len);
-	    std::cerr << std::endl;
-	  });
-	});
-
-	req->on_close([&sess](uint32_t error_code) {
-	  // shutdown session after first request was done.
-	  sess.shutdown();
-	});
-      });
-
-      sess.on_error([](const boost::system::error_code &ec) {
-	std::cerr << "error: " << ec.message() << std::endl;
-      });
-
-      io_service.run();
-    }
-
-``nghttp2::asio_http2::client::session`` object takes
-``boost::asio::io_service`` object and remote server address.  When
-connection is made, the callback function passed to
-``nghttp2::asio_http2::client::on_connect`` is invoked with connected
-address as its parameter.  After this callback call, use
-``nghttp2::asio_http2::session::submit`` to send request to the
-server.  You can submit multiple requests at once without waiting for
-the completion of previous request.
-
-The life time of req and res object ends after the callback set by
-``nghttp2::asio_http2::server::request::on_close`` function.
-Application must not use those objects after this call.
-
-Normally, client does not stop even after all requests are done unless
-connection is lost.  To stop client, call
-``nghttp2::asio_http2::server::session::shutdown()``.
-

-
-	req->on_response([&sess](const response &res) {
-	  std::cerr << "response received!" << std::endl;
-	  res.on_data([&sess](const uint8_t *data, std::size_t len) {
-	    std::cerr.write(reinterpret_cast<const char *>(data), len);
-	    std::cerr << std::endl;
-	  });
-	});
-
-	req->on_push([](const request &push) {
-	  std::cerr << "push request received!" << std::endl;
-	  push.on_response([](const response &res) {
-	    std::cerr << "push response received!" << std::endl;
-	    res.on_data([](const uint8_t *data, std::size_t len) {

-	std::cerr << "error: " << ec.message() << std::endl;
-      });
-
-      io_service.run();
-    }
-
-The above sample code demonstrates how to enable SSL/TLS and receive
-server push.  Currently,
-``nghttp2::asio_http2::client::configure_tls_context`` function setups
-NPN callbacks for SSL/TLS context for HTTP/2 use.
-
-To receive server push, use
-``nghttp2::asio_http2::client::request::on_push`` function to set
-callback function which is invoked when server push request is
-arrived.  The callback function takes
-``nghttp2::asio_http2::client::request`` object, which contains the
-pushed request.  To get server push response, set callback using
-``nghttp2::asio_http2::client::request::on_response``.
-
-As stated in the previous section, client does not stop automatically
-as long as HTTP/2 session is fine and connection is alive.  We don't
-call ``nghttp2::asio_http2::client::session::shutdown`` in this
-example, so the program does not terminate after all responses are
-received.  Hit Ctrl-C to terminate the program.
-
-Multiple concurrent requests
-++++++++++++++++++++++++++++
-
-.. code-block:: cpp
-
-    #include <iostream>
-
-    #include <nghttp2/asio_http2_client.h>
-
-    using boost::asio::ip::tcp;
-
-    using namespace nghttp2::asio_http2;
-    using namespace nghttp2::asio_http2::client;

-    int main(int argc, char *argv[]) {

-
-	auto printer = [](const response &res) {
-	  res.on_data([](const uint8_t *data, std::size_t len) {
-	    std::cerr.write(reinterpret_cast<const char *>(data), len);
-	    std::cerr << std::endl;
-	  });
-	};
-
-	std::size_t num = 3;
-	auto count = std::make_shared<int>(num);
-
-	for (std::size_t i = 0; i < num; ++i) {

-	std::cerr << "error: " << ec.message() << std::endl;
-      });
-
-      io_service.run();
-    }
-
-Here is the sample to send 3 requests at once.  Depending on the
-server settings, these requests are processed out-of-order.  In this
-example, we have a trick to shutdown session after all requests were
-done.  We made ``count`` object which is shared pointer to int and is
-initialized to 3.  On each request closure (the invocation of the
-callback set by ``nghttp2::asio_http2::client::request::on_close``),
-we decrement the count.  If count becomes 0, we are sure that all
-requests have been done and initiate shutdown.
