-The order of transmission of the HTTP/2 frames
----------------------------------------------
-
-This section describes the internals of libnghttp2 about the
-scheduling of transmission of HTTP/2 frames.  This is pretty much
-internal stuff, so the details could change in the future versions of
-the library.
-
-libnghttp2 categorizes HTTP/2 frames into 4 categories: urgent,
-regular, syn_stream, and data in the order of higher priority.
-
-The urgent category includes PING and SETTINGS.  They are sent with
-highest priority.  The order inside the category is FIFO.
-
-The regular category includes frames other than PING, SETTINGS, DATA,
-and HEADERS which does not create stream (which counts toward
-concurrent stream limit).  The order inside the category is FIFO.
-
-The syn_stream category includes HEADERS frame which creates stream,
-that counts toward the concurrent stream limit.
-
-The data category includes DATA frame, and the scheduling among DATA
-frames are determined by HTTP/2 dependency tree.
-
-If the application wants to send frames in the specific order, and the
-default transmission order does not fit, it has to schedule frames by
-itself using the callbacks (e.g.,
-:type:`nghttp2_on_frame_send_callback`).
-
-RST_STREAM has special side effect when it is submitted by
-`nghttp2_submit_rst_stream()`.  It cancels all pending HEADERS and
-DATA frames whose stream ID matches the one in the RST_STREAM frame.
-This may cause unexpected behaviour for the application in some cases.
-For example, suppose that application wants to send RST_STREAM after
-sending response HEADERS and DATA.  Because of the reason we mentioned
-above, the following code does not work:
-
-.. code-block:: c
-
-    nghttp2_submit_response(...)
-    nghttp2_submit_rst_stream(...)
-
-RST_STREAM cancels HEADERS (and DATA), and just RST_STREAM is sent.
-The correct way is use :type:`nghttp2_on_frame_send_callback`, and
-after HEADERS and DATA frames are sent, issue
-`nghttp2_submit_rst_stream()`.  FYI,
-:type:`nghttp2_on_frame_not_send_callback` tells you why frames are

-nghttpx server accepts any of the identity and secret pairs in the
-file.  The default cipher suite list does not contain PSK cipher
-suites.  In order to use PSK, PSK cipher suite must be enabled by
-using :option:`--ciphers` option.  The desired PSK cipher suite may be
-listed in `HTTP/2 cipher black list
-<https://tools.ietf.org/html/rfc7540#appendix-A>`_.  In order to use
-such PSK cipher suite with HTTP/2, disable HTTP/2 cipher black list by
-using :option:`--no-http2-cipher-black-list` option.  But you should
-understand its implications.
-
-At the time of writing, even if only PSK cipher suites are specified
-in :option:`--ciphers` option, certificate and private key are still
-required.
-
-For backend connection, use :option:`--client-psk-secrets` option to
-specify a file which contains single PSK identity and secret.  The
-format is the same as the file used by :option:`--psk-secrets`
-described above, but only first identity and secret pair is solely

-TLSv1.3
-------
-
-As of nghttpx v1.34.0, if it is built with OpenSSL 1.1.1 or later, it
-supports TLSv1.3.  0-RTT data is supported, but by default its
-processing is postponed until TLS handshake completes to mitigate
-replay attack.  This costs extra round trip and reduces effectiveness
-of 0-RTT data.  :option:`--tls-no-postpone-early-data` makes nghttpx
-not wait for handshake to complete before forwarding request included
-in 0-RTT to get full potential of 0-RTT data.  In this case, nghttpx
-adds ``Early-Data: 1`` header field when forwarding a request to a
-backend server.  All backend servers should recognize this header
-field and understand that there is a risk for replay attack.  See `RFC
-8470 <https://tools.ietf.org/html/rfc8470>`_ for ``Early-Data`` header
-field.
-
-nghttpx disables anti replay protection provided by OpenSSL.  The anti
-replay protection of OpenSSL requires that a resumed request must hit
-the same server which generates the session ticket.  Therefore it
-might not work nicely in a deployment where there are multiple nghttpx
-instances sharing ticket encryption keys via memcached.
-
-Because TLSv1.3 completely changes the semantics of cipher suite
-naming scheme and structure, nghttpx provides the new option
-:option:`--tls13-ciphers` and :option:`--tls13-client-ciphers` to
-change preferred cipher list for TLSv1.3.
-
-WebSockets over HTTP/2
----------------------
-
-nghttpx supports `RFC 8441 <https://tools.ietf.org/html/rfc8441>`_
-Bootstrapping WebSockets with HTTP/2 for both frontend and backend
-connections.  This feature is enabled by default and no configuration
-is required.
-
-Migration from nghttpx v1.18.x or earlier
-----------------------------------------
-
-As of nghttpx v1.19.0, :option:`--ciphers` option only changes cipher
-list for frontend TLS connection.  In order to change cipher list for
-backend connection, use :option:`--client-ciphers` option.
-
-Similarly, :option:`--no-http2-cipher-black-list` option only disables
-HTTP/2 cipher black list for frontend connection.  In order to disable
-HTTP/2 cipher black list for backend connection, use
-:option:`--client-no-http2-cipher-black-list` option.
-
-``--accept-proxy-protocol`` option was deprecated.  Instead, use
-``proxyproto`` parameter in :option:`--frontend` option to enable
-PROXY protocol support per frontend.
-

-
-fuzz_target.cc contains an entry point of fuzzer.  corpus directory
-contains initial data for fuzzer.
-
-The file name of initial data under corpus is the lower-cased hex
-string of SHA-256 hash of its own content.
-
-corpus/h2spec contains input data which was recorded when we ran
-`h2spec <https://github.com/summerwind/h2spec>`_ against nghttpd.
-
-corpus/nghttp contains input data which was recorded when we ran
-nghttp against nghttpd with some varying command line options of
-nghttp.

-
-To build fuzz_target.cc, make sure that libnghttp2 is built with

-
-.. code-block:: text
-
-    CPPFLAGS="-fsanitize-coverage=edge -fsanitize=address"
-    LDFLAGS="-fsanitize-coverage=edge -fsanitize=address"

Tatsuhiro Tsujikawa	2c0afa00aa	Fix GOAWAY race with new incoming stream on server side Revert part of `16c46114dc` to fix race condition that incoming stream after sending GOAWAY causes connection error. The strict stream handling introduced in the above commit does not handle several cases well (e.g., GOAWAY race, and refusing streams because of concurrency limit).	2016-09-10 12:48:26 +09:00
