2f23eac179 nghttp2_hd: Fail inflate immediately if ctx.bad is nonzero

which causes assertion error.  Add sanity assertion for index

API Reference
=============
Includes
--------
To use the public APIs, include ``nghttp2/nghttp2.h``::
#include <nghttp2/nghttp2.h>
The header files are also available online: :doc:`nghttp2.h` and
:doc:`nghttp2ver.h`.
Remarks
-------
Do not call `nghttp2_session_send`, `nghttp2_session_recv` or
`nghttp2_session_mem_recv` from the nghttp2 callback functions
directly or indirectly. It will lead to the crash. You can submit
requests or frames in the callbacks then call `nghttp2_session_send`,
`nghttp2_session_recv` or `nghttp2_session_mem_recv` outside of the
callbacks.

with "unix:" (e.g., unix:/var/run/backend.sock)
Default: ``127.0.0.1,80``
.. option:: -f, --frontend=<HOST,PORT>
Set frontend host and port. If <HOST> is '\*', it
assumes all addresses including both IPv4 and IPv6.
UNIX domain socket can be specified by prefixing path
name with "unix:" (e.g., unix:/var/run/nghttpx.sock)
Default: ``*,3000``
.. option:: --backlog=<N>
Set listen backlog size.
Default: ``512``
.. option:: --backend-ipv4
Resolve backend hostname to IPv4 address only.
.. option:: --backend-ipv6
Resolve backend hostname to IPv6 address only.
.. option:: --backend-http-proxy-uri=<URI>
Specify proxy URI in the form
http://[<USER>:<PASS>@]<PROXY>:<PORT>. If a proxy
requires authentication, specify <USER> and <PASS>.
Note that they must be properly percent-encoded. This
proxy is used when the backend connection is HTTP/2.
First, make a CONNECT request to the proxy and it
connects to the backend on behalf of nghttpx. This
forms tunnel. After that, nghttpx performs SSL/TLS
handshake with the downstream through the tunnel. The
timeouts when connecting and making CONNECT request can
be specified by :option:`--backend-read-timeout` and
:option:`--backend-write-timeout` options.

.. option:: --tls-ticket-key-file=<PATH>
Path to file that contains 48 bytes random data to
construct TLS session ticket parameters. This options
can be used repeatedly to specify multiple ticket
parameters. If several files are given, only the first
key is used to encrypt TLS session tickets. Other keys
are accepted but server will issue new session ticket
with first key. This allows session key rotation.
Please note that key rotation does not occur
automatically. User should rearrange files or change
options values and restart nghttpx gracefully. If
opening or reading given file fails, all loaded keys are
discarded and it is treated as if none of this option is
given. If this option is not given or an error occurred
while opening or reading a file, key is generated
automatically and renewed every 12hrs. At most 2 keys
are stored in memory.

Mode
~~~~
.. describe:: (default mode)
Accept HTTP/2, SPDY and HTTP/1.1 over SSL/TLS. If
:option:`--frontend-no-tls` is used, accept HTTP/2 and HTTP/1.1.
The incoming HTTP/1.1 connection can be upgraded to
HTTP/2 through HTTP Upgrade. The protocol to the
backend is HTTP/1.1.
.. option:: -s, --http2-proxy
Like default mode, but enable secure proxy mode.
.. option:: --http2-bridge
Like default mode, but communicate with the backend in
HTTP/2 over SSL/TLS. Thus the incoming all connections
are converted to HTTP/2 connection and relayed to the
backend. See :option:`--backend-http-proxy-uri` option if you are
behind the proxy and want to connect to the outside
HTTP/2 proxy.
.. option:: --client
Accept HTTP/2 and HTTP/1.1 without SSL/TLS. The
incoming HTTP/1.1 connection can be upgraded to HTTP/2
connection through HTTP Upgrade. The protocol to the
backend is HTTP/2. To use nghttpx as a forward proxy,
use :option:`-p` option instead.
.. option:: -p, --client-proxy
Like :option:`--client` option, but it also requires the request
path from frontend must be an absolute URI, suitable for
use as a forward proxy.
Logging
~~~~~~~
.. option:: -L, --log-level=<LEVEL>
Set the severity level of log output. <LEVEL> must be
one of INFO, NOTICE, WARN, ERROR and FATAL.
Default: ``NOTICE``
.. option:: --accesslog-file=<PATH>
Set path to write access log. To reopen file, send USR1
signal to nghttpx.
.. option:: --accesslog-syslog
Send access log to syslog. If this option is used,

.. option:: --accesslog-format=<FORMAT>
Specify format string for access log. The default
format is combined format. The following variables are
available:
* $remote_addr: client IP address.
* $time_local: local time in Common Log format.
* $time_iso8601: local time in ISO 8601 format.
* $request: HTTP request line.
* $status: HTTP response status code.
* $body_bytes_sent: the number of bytes sent to client
as response body.
* $http_<VAR>: value of HTTP request header <VAR> where
'_' in <VAR> is replaced with '-'.
* $remote_port: client port.
* $server_port: server port.
* $request_time: request processing time in seconds with
milliseconds resolution.
* $pid: PID of the running process.
* $alpn: ALPN identifier of the protocol which generates
the response. For HTTP/1, ALPN is always http/1.1,
regardless of minor version.
Default: ``$remote_addr - - [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent"``
.. option:: --errorlog-file=<PATH>
Set path to write error log. To reopen file, send USR1
signal to nghttpx. stderr will be redirected to the
error log file unless :option:`--errorlog-syslog` is used.

:option:`--client` and default mode. For :option:`\--http2-proxy` and
:option:`--client-proxy` mode, location header field will not be
altered regardless of this option.
.. option:: --no-host-rewrite
Don't rewrite host and :authority header fields on
:option:`--http2-bridge`\, :option:`--client` and default mode. For
:option:`--http2-proxy` and :option:`\--client-proxy` mode, these headers
will not be altered regardless of this option.
.. option:: --altsvc=<PROTOID,PORT[,HOST,[ORIGIN]]>
Specify protocol ID, port, host and origin of
alternative service. <HOST> and <ORIGIN> are optional.
They are advertised in alt-svc header field or HTTP/2
ALTSVC frame. This option can be used multiple times to
specify multiple alternative services. Example:

(hours, minutes, seconds and milliseconds, respectively). If a unit
is omitted, a second is used as unit.
FILES

*/etc/nghttpx/nghttpx.conf*
The default configuration file path nghttpx searches at startup.
The configuration file path can be changed using :option:`--conf`
option.
Those lines which are staring ``#`` are treated as comment.
The option name in the configuration file is the long command-line
option name with leading ``--`` stripped (e.g., ``frontend``). Put
``=`` between option name and value. Don't put extra leading or
trailing spaces.
The options which do not take argument in the command-line *take*
argument in the configuration file. Specify ``yes`` as an argument
(e.g., ``http2-proxy=yes``). If other string is given, it is
ignored.
To specify private key and certificate file which are given as
positional arguments in commnad-line, use ``private-key-file`` and
``certificate-file``.
:option:`--conf` option cannot be used in the configuration file and
will be ignored if specified.
SIGNALS
-------
SIGQUIT
Shutdown gracefully. First accept pending connections and stop
accepting connection. After all connections are handled, nghttpx
exits.
SIGUSR1
Reopen log files.
SIGUSR2
Fork and execute nghttpx. It will execute the binary in the same
path with same command-line arguments and environment variables.
After new process comes up, sending SIGQUIT to the original process
to perform hot swapping.
SERVER PUSH
-----------
nghttpx supports HTTP/2 server push in default mode. nghttpx looks
for Link header field (`RFC 5988
<http://tools.ietf.org/html/rfc5988>`_) in response headers from
backend server and extracts URI-reference with parameter
``rel=preload`` (see `preload
<http://w3c.github.io/preload/#interoperability-with-http-link-header>`_)
and pushes those URIs to the frontend client. Here is a sample Link
header field to initiate server push:
.. code-block:: http
Link: </fonts/font.woff>; rel=preload
Link: </css/theme.css>; rel=preload
Currently, the following restrictions are applied for server push:
1. URI-reference must not contain authority. If it exists, it is not
pushed. ``/fonts/font.woff`` and ``css/theme.css`` are eligible to
be pushed. ``https://example.org/fonts/font.woff`` and
``//example.org/css/theme.css`` are not.
2. The associated stream must have method "GET" or "POST". The
associated stream's status code must be 200.
These limitations may be loosened in the future release.
UNIX DOMAIN SOCKET
------------------
nghttpx supports UNIX domain socket with a filename for both frontend
and backend connections.
Please note that current nghttpx implementation does not delete a
socket with a filename. And on start up, if nghttpx detects that the
specified socket already exists in the file system, nghttpx first
deletes it. However, if SIGUSR2 is used to execute new binary and
both old and new configurations use same filename, new binary does not
delete the socket and continues to use it.
OCSP STAPLING
-------------
OCSP query is done using external perl script ``fetch-ocsp-response``,
which has been developed as part of h2o project
(https://github.com/h2o/h2o).
The script file is usually installed under
``$(prefix)/share/nghttp2/`` directory. The actual path to script can
be customized using :option:`--fetch-ocsp-response-file` option.

Programmers' Guide
==================
Includes
--------
To use the public APIs, include ``nghttp2/nghttp2.h``::
#include <nghttp2/nghttp2.h>
The header files are also available online: :doc:`nghttp2.h` and
:doc:`nghttp2ver.h`.
Remarks
-------
Do not call `nghttp2_session_send()`, `nghttp2_session_mem_send()`,
`nghttp2_session_recv()` or `nghttp2_session_mem_recv()` from the
nghttp2 callback functions directly or indirectly. It will lead to the
crash. You can submit requests or frames in the callbacks then call
these functions outside the callbacks.
Currently, `nghttp2_session_send()` and `nghttp2_session_mem_send()`
do not send client connection preface
(:macro:`NGHTTP2_CLIENT_CONNECTION_PREFACE`). The applications are
responsible to send it before sending any HTTP/2 frames using these
functions if :type:`nghttp2_session` is configured as client.
Similarly, `nghttp2_session_recv()` and `nghttp2_session_mem_recv()`
do not consume client connection preface unless
`nghttp2_option_set_recv_client_preface()` is used with nonzero option
value. The applications are responsible to receive it before calling
these functions if :type:`nghttp2_session` is configured as server and
`nghttp2_option_set_recv_client_preface()` is not used.
.. _http-messaging:
HTTP Messaging
--------------
By default, nghttp2 library checks HTTP messaging rules described in
`HTTP/2 specification, section 8
<https://tools.ietf.org/html/draft-ietf-httpbis-http2-17#section-8>`_.
Everything described in that section is not validated however. We
briefly describe what the library does in this area. In the following
description, without loss of generality we omit CONTINUATION frame
since they must follow HEADERS frame and are processed atomically. In
other words, they are just one big HEADERS frame. To disable these
validations, use `nghttp2_option_set_no_http_messaging()`.
For HTTP request, including those carried by PUSH_PROMISE, HTTP
message starts with one HEADERS frame containing request headers. It
is followed by zero or more DATA frames containing request body, which
is followed by zero or one HEADERS containing trailer headers. The
request headers must include ":scheme", ":method" and ":path" pseudo
header fields unless ":method" is not "CONNECT". ":authority" is
optional, but nghttp2 requires either ":authority" or "Host" header
field must be present. If ":method" is "CONNECT", the request headers
must include ":method" and ":authority" and must omit ":scheme" and
":path".
For HTTP response, HTTP message starts with zero or more HEADERS
frames containing non-final response (status code 1xx). They are
followed by one HEADERS frame containing final response headers
(non-1xx). It is followed by zero or more DATA frames containing
response body, which is followed by zero or one HEADERS containing
trailer headers. The non-final and final response headers must
contain ":status" pseudo header field containing 3 digits only.
All request and response headers must include exactly one valid value
for each pseudo header field. Additionally nghttp2 requires all
request headers must not include more than one "Host" header field.
HTTP/2 prohibits connection-specific header fields. The following
header fields must not appear: "Connection", "Keep-Alive",
"Proxy-Connection", "Transfer-Encoding" and "Upgrade". Additionally,
"TE" header field must not include any value other than "trailers".
Each header field name and value must obey the field-name and
field-value production rules described in `RFC 7230, section
3.2. <https://tools.ietf.org/html/rfc7230#section-3.2>`_.
Additionally, all field name must be lower cased. While the pseudo
header fields must satisfy these rules, we just ignore illegal regular
headers (this means that these header fields are not passed to
application callback). This is because these illegal header fields
are floating around in existing internet and resetting stream just
because of this may break many web sites. This is especially true if
we forward to or translate from HTTP/1 traffic.
For "http" or "https" URIs, ":path" pseudo header fields must start
with "/". The only exception is OPTIONS request, in that case, "*" is
allowed in ":path" pseudo header field to represent system-wide
OPTIONS request.
With the above validations, nghttp2 library guarantees that header
field name passed to `nghttp2_on_header_callback()` is not empty.
Also required pseudo headers are all present and not empty.
nghttp2 enforces "Content-Length" validation as well. All request or
response headers must not contain more than one "Content-Length"
header field. If "Content-Length" header field is present, it must be
parsed as 64 bit signed integer. The sum of data length in the
following DATA frames must match with the number in "Content-Length"
header field if it is present (this does not include padding bytes).
Any deviation results in stream error of type PROTOCOL_ERROR. If
error is found in PUSH_PROMISE frame, stream error is raised against
promised stream.

Building Android binary
=======================
In this article, we briefly describe how to build Android binary using
`Android NDK <http://developer.android.com/tools/sdk/ndk/index.html>`_
cross-compiler on Debian Linux.
The easiest way to build android binary is use Dockerfile.android.
See Dockerfile.android for more details. If you cannot use
Dockerfile.android for whatever reason, continue to read the rest of
this article.
We offer ``android-config`` and ``android-make`` scripts to make the
build easier. To make these script work, NDK toolchain must be
installed in the following way. First, let us introduce
``ANDROID_HOME`` environment variable. We need to install toolchain
under ``$ANDROID_HOME/toolchain``. An user can freely choose the path
for ``ANDROID_HOME``. For example, to install toolchain under
``$ANDROID_HOME/toolchain``, do this in the the directory where NDK is
unpacked::
$ build/tools/make-standalone-toolchain.sh \
--install-dir=$ANDROID_HOME/toolchain \
--toolchain=arm-linux-androideabi-4.9 \
--llvm-version=3.5 \
--platform=android-16
The additional flag ``--system=linux-x86_64`` may be required if you
are using x86_64 system.
The platform level is not important here because we don't use Android
specific C/C++ API.
The dependent libraries, such as OpenSSL and libev should be built
with the toolchain and installed under ``$ANDROID_HOME/usr/local``.
We recommend to build these libraries as static library to make the
deployment easier. libxml2 support is currently disabled.
We use zlib which comes with Android NDK, so we don't have to build it
by ourselves.
If SPDY support is required for nghttpx and h2load, build and install
spdylay as well.
Before running ``android-config`` and ``android-make``,
``ANDROID_HOME`` environment variable must be set to point to the
correct path. Also add ``$ANDROID_HOME/toolchain/bin`` to ``PATH``::
$ export PATH=$PATH:$ANDROID_HOME/toolchain/bin
To configure OpenSSL, use the following script:
.. code-block:: sh
#!/bin/sh
if [ -z "$ANDROID_HOME" ]; then
echo 'No $ANDROID_HOME specified.'
exit 1
fi
PREFIX=$ANDROID_HOME/usr/local
TOOLCHAIN=$ANDROID_HOME/toolchain
PATH=$TOOLCHAIN/bin:$PATH
export CROSS_COMPILE=$TOOLCHAIN/bin/arm-linux-androideabi-
./Configure --prefix=$PREFIX android
And run ``make install`` to build and install.
We cannot compile libev without modification. Apply `this patch
<https://gist.github.com/tatsuhiro-t/48c45f08950f587180ed>`_ before
configuring libev. This patch is for libev-4.19. After applying the
patch, to configure libev, use the following script:
.. code-block:: sh
#!/bin/sh
if [ -z "$ANDROID_HOME" ]; then
echo 'No $ANDROID_HOME specified.'
exit 1
fi
PREFIX=$ANDROID_HOME/usr/local
TOOLCHAIN=$ANDROID_HOME/toolchain
PATH=$TOOLCHAIN/bin:$PATH
./configure \
--host=arm-linux-androideabi \
--build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \
--prefix=$PREFIX \
--disable-shared \
--enable-static \
CPPFLAGS=-I$PREFIX/include \
LDFLAGS=-L$PREFIX/lib
And run ``make install`` to build and install.
To configure spdylay, use the following script:
.. code-block:: sh
if [ -z "$ANDROID_HOME" ]; then
echo 'No $ANDROID_HOME specified.'
exit 1
fi
PREFIX=$ANDROID_HOME/usr/local
TOOLCHAIN=$ANDROID_HOME/toolchain
PATH=$TOOLCHAIN/bin:$PATH
./configure \
--disable-shared \
--host=arm-linux-androideabi \
--build=`dpkg-architecture -qDEB_BUILD_GNU_TYPE` \
--prefix=$PREFIX \
--without-libxml2 \
--disable-src \
--disable-examples \
CPPFLAGS="-I$PREFIX/include" \
PKG_CONFIG_LIBDIR="$PREFIX/lib/pkgconfig" \
LDFLAGS="-L$PREFIX/lib"
And run ``make install`` to build and install. After spdylay
installation, edit $ANDROID_HOME/usr/local/lib/pkgconfig/libspdylay.pc
and remove the following line::
Requires.private: zlib
After prerequisite libraries are prepared, run ``android-config`` and
then ``android-make`` to compile nghttp2 source files.
If all went well, application binaries, such as nghttpx, are created
under src directory. Strip debugging information from the binary
using the following command::
$ arm-linux-androideabi-strip src/nghttpx

Contribution Guidelines
=======================
[This text was composed based on 1.2. License section of curl/libcurl
project.]
When contributing with code, you agree to put your changes and new
code under the same license nghttp2 is already using unless stated and
agreed otherwise.
When changing existing source code, you do not alter the copyright of
the original file(s). The copyright will still be owned by the
original creator(s) or those who have been assigned copyright by the
original author(s).
By submitting a patch to the nghttp2 project, you are assumed to have
the right to the code and to be allowed by your employer or whatever
to hand over that patch/code to us. We will credit you for your
changes as far as possible, to give credit but also to keep a trace
back to who made what changes. Please always provide us with your
full real name when contributing!
Coding style
------------
We use clang-format to format source code consistently. The
clang-format configuration file .clang-format is located at the root
directory. Since clang-format produces slightly different results
between versions, we currently use clang-format which comes with
clang-3.5.
To detect any violation to the coding style, we recommend to setup git
pre-commit hook to check coding style of the changes you introduced.
The pre-commit file is located at the root directory. Copy it under
.git/hooks and make sure that it is executable. The pre-commit script
uses clang-format-diff.py to detect any style errors. If it is not in
your PATH or it exists under different name (e.g.,
clang-format-diff-3.5 in debian), either add it to PATH variable or
add git option ``clangformatdiff.binary`` to point to the script.
For emacs users, integrating clang-format to emacs is very easy.
clang-format.el should come with clang distribution. If it is not
found, download it from `here
<https://llvm.org/svn/llvm-project/cfe/trunk/tools/clang-format/clang-format.el>`_.
And add these lines to your .emacs file:
.. code-block:: lisp
;; From
;; https://code.google.com/p/chromium/wiki/Emacs#Use_Google's_C++_style!
(load "/<path/to>/clang-format.el")
(add-hook 'c-mode-common-hook
(function (lambda () (local-set-key (kbd "TAB")
'clang-format-region))))

h2load - HTTP/2 benchmarking tool - HOW-TO
==========================================
h2load is benchmarking tool for HTTP/2. If built with
spdylay (http://tatsuhiro-t.github.io/spdylay/) library, it also
supports SPDY protocol. It supports SSL/TLS and clear text for both
HTTP/2 and SPDY.
Basic Usage
-----------
In order to set benchmark settings, specify following 3 options.
``-n``
The number of total requests. Default: 1
``-c``
The number of concurrent clients. Default: 1
``-m``
The max concurrent streams to issue per client.
If ``auto`` is given, the number of given URIs is used.
Default: ``auto``
Here is a command-line to perform benchmark to URI \https://localhost
using total 100000 requests, 100 concurrent clients and 10 max
concurrent streams::
$ h2load -n100000 -c100 -m10 https://localhost
The benchmarking result looks like this::
finished in 0 sec, 385 millisec and 851 microsec, 2591 req/s, 1689 kbytes/s
requests: 1000 total, 1000 started, 1000 done, 1000 succeeded, 0 failed, 0 errored
status codes: 1000 2xx, 0 3xx, 0 4xx, 0 5xx
traffic: 667500 bytes total, 28700 bytes headers, 612000 bytes data
The number of ``failed`` is the number of requests returned with non
2xx status. The number of ``error`` is the number of ``failed`` plus
the number of requests which failed with connection error.
The number of ``total`` in ``traffic`` is the received application
data. If SSL/TLS is used, this number is calculated after decryption.
The number of ``headers`` is the sum of payload size of response
HEADERS (or SYN_REPLY for SPDY). This number comes before
decompressing header block. The number of ``data`` is the sum of
response body.
Flow Control
------------
HTTP/2 and SPDY/3 or later employ flow control and it may affect
benchmarking results. To adjust receiver flow control window size,
there is following options:
``-w``
Sets the stream level initial window size to
(2**<N>)-1. For SPDY, 2**<N> is used instead.
``-W``
Sets the connection level initial window size to
(2**<N>)-1. For SPDY, if <N> is strictly less
than 16, this option is ignored. Otherwise
2**<N> is used for SPDY.
Multi-Threading
---------------
Sometimes benchmarking client itself becomes a bottleneck. To remedy
this situation, use ``-t`` option to specify the number of native
thread to use.
``-t``
The number of native threads. Default: 1
Selecting protocol for clear text
---------------------------------
By default, if \http:// URI is given, HTTP/2 protocol is used. To
change the protocol to use for clear text, use ``-p`` option.
Multiple URIs
-------------
If multiple URIs are specified, they are used in round robin manner.
.. note::
Please note that h2load uses sheme, host and port in the first URI
and ignores those parts in the rest of the URIs.

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 responde 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 paramter. 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()``.
Recieve server push and enable SSL/TLS
++++++++++++++++++++++++++++++++++++++
.. 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;
boost::asio::ssl::context tls(boost::asio::ssl::context::sslv23);
tls.set_default_verify_paths();
// disabled to make development easier...
// tls_ctx.set_verify_mode(boost::asio::ssl::verify_peer);
configure_tls_context(ec, tls);
// connect to localhost:3000
session sess(io_service, tls, "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([&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.write(reinterpret_cast<const char *>(data), len);
std::cerr << std::endl;
});
});
});
});
sess.on_error([](const boost::system::error_code &ec) {
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[]) {
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 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) {
auto req = sess.submit(ec, "GET",
"http://localhost:3000/" + std::to_string(i + 1));
req->on_response(printer);
req->on_close([&sess, count](uint32_t error_code) {
if (--*count == 0) {
// shutdown session after |num| requests were done.
sess.shutdown();
}
});
}
});
sess.on_error([](const boost::system::error_code &ec) {
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.

nghttpx - HTTP/2 proxy - HOW-TO
===============================
nghttpx is a proxy translating protocols between HTTP/2 and other
protocols (e.g., HTTP/1, SPDY). It operates in several modes and each
mode may require additional programs to work with. This article
describes each operation mode and explains the intended use-cases. It
also covers some useful options later.
Default mode
------------
If nghttpx is invoked without any ``-s``, ``-p`` and ``--client``, it
operates in default mode. In this mode, nghttpx frontend listens for
HTTP/2 requests and translates them to HTTP/1 requests. Thus it works
as reverse proxy (gateway) for HTTP/2 clients to HTTP/1 web server.
HTTP/1 requests are also supported in frontend as a fallback. If
nghttpx is linked with spdylay library and frontend connection is
SSL/TLS, the frontend also supports SPDY protocol.
By default, this mode's frontend connection is encrypted using
SSL/TLS. So server's private key and certificate must be supplied to
the command line (or through configuration file). In this case, the
fontend protocol selection will is done via ALPN or NPN.
With ``--frontend-no-tls`` option, user can turn off SSL/TLS in
frontend connection. In this case, SPDY protocol is not available
even if spdylay library is liked to nghttpx. HTTP/2 and HTTP/1 are
available on the frontend and a HTTP/1 connection can be upgraded to
HTTP/2 using HTTP Upgrade. Starting HTTP/2 connection by sending
HTTP/2 connection preface is also supported.
The backend is supposed to be HTTP/1 Web server. For example, to make
nghttpx listen to encrypted HTTP/2 requests at port 8443, and a
backend HTTP/1 web server is configured to listen to HTTP/1 request at
port 8080 in the same host, run nghttpx command-line like this::
$ nghttpx -f0.0.0.0,8443 -b127.0.0.1,8080 /path/to/server.key /path/to/server.crt
Then HTTP/2 enabled client can access to the nghttpx in HTTP/2. For
example, you can send GET request to the server using nghttp::
$ nghttp -nv https://localhost:8443/
HTTP/2 proxy mode
-----------------
If nghttpx is invoked with ``-s`` option, it operates in HTTP/2 proxy
mode. The supported protocols in frontend and backend connections are
the same in `default mode`_. The difference is that this mode acts
like forward proxy and assumes the backend is HTTP/1 proxy server
(e.g., squid, traffic server). So HTTP/1 request must include
absolute URI in request line.
By default, frontend connection is encrypted. So this mode is also
called secure proxy. If nghttpx is linked with spdylay, it supports
SPDY protocols and it works as so called SPDY proxy.
With ``--frontend-no-tls`` option, SSL/TLS is turned off in frontend
connection, so the connection gets insecure.
The backend must be HTTP/1 proxy server. nghttpx supports multiple
backend server addresses. It translates incoming requests to HTTP/1
request to backend server. The backend server performs real proxy
work for each request, for example, dispatching requests to the origin
server and caching contents.
For example, to make nghttpx listen to encrypted HTTP/2 requests at
port 8443, and a backend HTTP/1 proxy server is configured to listen
to HTTP/1 request at port 8080 in the same host, run nghttpx
command-line like this::
$ nghttpx -s -f'*,8443' -b127.0.0.1,8080 /path/to/server.key /path/to/server.crt
At the time of this writing, Firefox nightly supports HTTP/2 proxy.
Chromium can use nghttpx as secure (SPDY) proxy and will support
HTTP/2 proxy in the near future.
To make Firefox nightly or Chromium use nghttpx as HTTP/2 or SPDY
proxy, user has to create proxy.pac script file like this:
.. code-block:: javascript
function FindProxyForURL(url, host) {
return "HTTPS SERVERADDR:PORT";
}
``SERVERADDR`` and ``PORT`` is the hostname/address and port of the
machine nghttpx is running. Please note that both Firefox nightly and
Chromium require valid certificate for secure proxy.
For Firefox nightly, open Preference window and select Advanced then
click Network tab. Clicking Connection Settings button will show the
dialog. Select "Automatic proxy configuration URL" and enter the path
to proxy.pac file, something like this::
file:///path/to/proxy.pac
For Chromium, use following command-line::
$ google-chrome --proxy-pac-url=file:///path/to/proxy.pac --use-npn
As HTTP/1 proxy server, Squid may work as out-of-box. Traffic server
requires to be configured as forward proxy. Here is the minimum
configuration items to edit::
CONFIG proxy.config.reverse_proxy.enabled INT 0
CONFIG proxy.config.url_remap.remap_required INT 0
Consult Traffic server `documentation
<https://docs.trafficserver.apache.org/en/latest/admin/forward-proxy.en.html>`_
to know how to configure traffic server as forward proxy and its
security implications.
Client mode
-----------
If nghttpx is invoked with ``--client`` option, it operates in client
mode. In this mode, nghttpx listens for plain, unencrypted HTTP/2 and
HTTP/1 requests and translates them to encrypted HTTP/2 requests to
the backend. User cannot enable SSL/TLS in frontend connection.
HTTP/1 frontend connection can be upgraded to HTTP/2 using HTTP
Upgrade. To disable SSL/TLS in backend connection, use
``--backend-no-tls`` option.
By default, the number of backend HTTP/2 connections per worker
(thread) is determined by number of ``-b`` option. To adjust this
value, use ``--backend-http2-connections-per-worker`` option.
The backend server is supporsed to be a HTTP/2 web server (e.g.,
nghttpd). The one use-case of this mode is utilize existing HTTP/1
clients to test HTTP/2 deployment. Suppose that HTTP/2 web server
listens to port 80 without encryption. Then run nghttpx as client
mode to access to that web server::
$ nghttpx --client -f127.0.0.1,8080 -b127.0.0.1,80 --backend-no-tls
.. note::
You may need ``-k`` option if HTTP/2 server enables SSL/TLS and
its certificate is self-signed. But please note that it is
insecure.
Then you can use curl to access HTTP/2 server via nghttpx::
$ curl http://localhost:8080/
Client proxy mode
-----------------
If nghttpx is invoked with ``-p`` option, it operates in client proxy
mode. This mode behaves like `client mode`_, but it works like
forward proxy. So HTTP/1 request must include absolute URI in request
line.
HTTP/1 frontend connection can be upgraded to HTTP/2 using HTTP
Upgrade. To disable SSL/TLS in backend connection, use
``--backend-no-tls`` option.
By default, the number of backend HTTP/2 connections per worker
(thread) is determined by number of ``-b`` option. To adjust this
value, use ``--backend-http2-connections-per-worker`` option.
The backend server must be a HTTP/2 proxy. You can use nghttpx in
`HTTP/2 proxy mode`_ as backend server. The one use-case of this mode
is utilize existing HTTP/1 clients to test HTTP/2 connections between
2 proxies. The another use-case is use this mode to aggregate local
HTTP/1 connections to one HTTP/2 backend encrypted connection. This
makes HTTP/1 clients which does not support secure proxy can use
secure HTTP/2 proxy via nghttpx client mode.
Suppose that HTTP/2 proxy listens to port 8443, just like we saw in
`HTTP/2 proxy mode`_. To run nghttpx in client proxy mode to access
that server, invoke nghttpx like this::
$ nghttpx -p -f127.0.0.1,8080 -b127.0.0.1,8443
.. note::
You may need ``-k`` option if HTTP/2 server's certificate is
self-signed. But please note that it is insecure.
Then you can use curl to issue HTTP request via HTTP/2 proxy::
$ curl --http-proxy=http://localhost:8080 http://www.google.com/
You can configure web browser to use localhost:8080 as forward
proxy.
HTTP/2 bridge mode
------------------
If nghttpx is invoked with ``--http2-bridge`` option, it operates in
HTTP/2 bridge mode. The supported protocols in frontend connections
are the same in `default mode`_. The protocol in backend is HTTP/2
only.
With ``--frontend-no-tls`` option, SSL/TLS is turned off in frontend
connection, so the connection gets insecure. To disable SSL/TLS in
backend connection, use ``--backend-no-tls`` option.
By default, the number of backend HTTP/2 connections per worker
(thread) is determined by number of ``-b`` option. To adjust this
value, use ``--backend-http2-connections-per-worker`` option.
The backend server is supporsed to be a HTTP/2 web server or HTTP/2
proxy. If backend server is HTTP/2 proxy, use
``--no-location-rewrite`` and ``--no-host-rewrite`` options to disable
rewriting location, host and :authority header field.
The use-case of this mode is aggregate the incoming connections to one
HTTP/2 connection. One backend HTTP/2 connection is created per
worker (thread).
Disable SSL/TLS
---------------
In `default mode`_, `HTTP/2 proxy mode`_ and `HTTP/2 bridge mode`_,
frontend connections are encrypted with SSL/TLS by default. To turn
off SSL/TLS, use ``--frontend-no-tls`` option. If this option is
used, the private key and certificate are not required to run nghttpx.
In `client mode`_, `client proxy mode`_ and `HTTP/2 bridge mode`_,
backend connections are encrypted with SSL/TLS by default. To turn
off SSL/TLS, use ``--backend-no-tls`` option.
Specifying additional CA certificate
------------------------------------
By default, nghttpx tries to read CA certificate from system. But
depending on the system you use, this may fail or is not supported.
To specify CA certificate manually, use ``--cacert`` option. The
specified file must be PEM format and can contain multiple
certificates.
By default, nghttpx validates server's certificate. If you want to
turn off this validation, knowing this is really insecure and what you
are doing, you can use ``-k`` option to disable certificate
validation.
Read/write rate limit
---------------------
nghttpx supports transfer rate limiting on frontend connections. You
can do rate limit per frontend connection for reading and writeing
individually.
To perform rate limit for reading, use ``--read-rate`` and
``--read-burst`` options. For writing, use ``--write-rate`` and
``--write-burst``.
Please note that rate limit is performed on top of TCP and nothing to
do with HTTP/2 flow control.
Rewriting location header field
-------------------------------
nghttpx automatically rewrites location response header field if the
following all conditions satisfy:
* URI in location header field is not absolute URI or is not https URI.
* URI in location header field includes non empty host component.
* host (without port) in URI in location header field must match the
host appearing in :authority or host header field.
When rewrite happens, URI scheme and port are replaced with the ones
used in frontend, and host is replaced with which appears in
:authority or host request header field. :authority header field has
precedence. If the above conditions are not met with the host value
in :authority header field, rewrite is retried with the value in host
header field.
Hot swapping
------------
nghttpx supports hot swapping using signals. The hot swapping in
nghttpx is multi step process. First send USR2 signal to nghttpx
process. It will do fork and execute new executable, using same
command-line arguments and environment variables. At this point, both
current and new processes can accept requests. To gracefully shutdown
current process, send QUIT signal to current nghttpx process. When
all existing frontend connections are done, the current process will
exit. At this point, only new nghttpx process exists and serves
incoming requests.
Re-opening log files
--------------------
When rotating log files, it is desirable to re-open log files after
log rotation daemon renamed existing log files. To tell nghttpx to
re-open log files, send USR1 signal to nghttpx process. It will
re-open files specified by ``--accesslog-file`` and
``--errorlog-file`` options.
Multiple backend addresses
--------------------------
nghttpx supports multiple backend addresses. To specify them, just
use ``-b`` option repeatedly. For example, to use backend1:8080 and
backend2:8080, use command-line like this: ``-bbackend1,8080
-bbackend2,8080``. For HTTP/2 backend, see also
``--backend-http2-connections-per-worker`` option.

Python API Reference
====================
.. py:module:: nghttp2
nghttp2 offers some high level Python API to C library. The bindings
currently provide HPACK compressor and decompressor classes and HTTP/2
server class.
The extension module is called ``nghttp2``.
``make`` will build the bindings. The target Python version is
determined by configure script. If the detected Python version is not
what you expect, specify a path to Python executable in ``PYTHON``
variable as an argument to configure script (e.g., ``./configure
PYTHON=/usr/bin/python3.4``).
HPACK API
---------
.. py:class:: HDDeflater(hd_table_bufsize_max=DEFLATE_MAX_HEADER_TABLE_SIZE)
This class is used to perform header compression. The
*hd_table_bufsize_max* limits the usage of header table in the
given amount of bytes. The default value is
:py:data:`DEFLATE_MAX_HEADER_TABLE_SIZE`. This is necessary
because the deflater and inflater share the same amount of header
table and the inflater decides that number. The deflater may not
want to use all header table size because of limited memory
availability. In that case, *hd_table_bufsize_max* can be used to
cap the upper limit of table size whatever the header table size is
chosen by the inflater.
.. py:method:: deflate(headers)
Deflates the *headers*. The *headers* must be sequence of tuple
of name/value pair, which are byte strings (not unicode string).
This method returns the deflated header block in byte string.
Raises the exception if any error occurs.
.. py:method:: set_no_refset(no_refset)
Tells the deflater not to use reference set if *no_refset* is
evaluated to ``True``. If that happens, on each subsequent
invocation of :py:meth:`deflate()`, deflater will clear up
refersent set.
.. py:method:: change_table_size(hd_table_bufsize_max)
Changes header table size to *hd_table_bufsize_max* byte. if
*hd_table_bufsize_max* is strictly larger than
``hd_table_bufsize_max`` given in constructor,
``hd_table_bufsize_max`` is used as header table size instead.
Raises the exception if any error occurs.
.. py:method:: get_hd_table()
Returns copy of current dynamic header table.
The following example shows how to deflate header name/value pairs:
.. code-block:: python
import binascii, nghttp2
deflater = nghttp2.HDDeflater()
res = deflater.deflate([(b'foo', b'bar'),
(b'baz', b'buz')])
print(binascii.b2a_hex(res))
.. py:class:: HDInflater()
This class is used to perform header decompression.
.. py:method:: inflate(data)
Inflates the deflated header block *data*. The *data* must be
byte string.
Raises the exception if any error occurs.
.. py:method:: change_table_size(hd_table_bufsize_max)
Changes header table size to *hd_table_bufsize_max* byte.
Raises the exception if any error occurs.
.. py:method:: get_hd_table()
Returns copy of current dynamic header table.
The following example shows how to inflate deflated header block:
.. code-block:: python
deflater = nghttp2.HDDeflater()
data = deflater.deflate([(b'foo', b'bar'),
(b'baz', b'buz')])
inflater = nghttp2.HDInflater()
hdrs = inflater.inflate(data)
print(hdrs)
.. py:function:: print_hd_table(hdtable)
Convenient function to print *hdtable* to the standard output. The
*hdtable* is the one retrieved by
:py:meth:`HDDeflater.get_hd_table()` or
:py:meth:`HDInflater.get_hd_table()`. This function does not work
if header name/value cannot be decoded using UTF-8 encoding.
In output, ``s=N`` means the entry occupies ``N`` bytes in header
table. If ``r=y``, then the entry is in the reference set.
.. py:data:: DEFAULT_HEADER_TABLE_SIZE
The default header table size, which is 4096 as per HTTP/2
specification.
.. py:data:: DEFLATE_MAX_HEADER_TABLE_SIZE
The default header table size for deflater. The initial value
is 4096.
HTTP/2 servers
--------------
.. note::
We use :py:mod:`asyncio` for HTTP/2 server classes. Therefore,
Python 3.4 or later is required to use these objects. To
explicitly configure nghttp2 build to use Python 3.4, specify the
``PYTHON`` variable to the path to Python 3.4 executable when
invoking configure script like this::
$ ./configure PYTHON=/usr/bin/python3.4
.. py:class:: HTTP2Server(address, RequestHandlerClass, ssl=None)
This class builds on top of the :py:mod:`asyncio` event loop. On
construction, *RequestHandlerClass* must be given, which must be a
subclass of :py:class:`BaseRequestHandler` class.
The *address* must be a tuple of hostname/IP address and port to
bind. If hostname/IP address is ``None``, all interfaces are
assumed.
To enable SSL/TLS, specify instance of :py:class:`ssl.SSLContext`
in *ssl*. Before passing *ssl* to
:py:func:`BaseEventLoop.create_server`, ALPN protocol identifiers
are set using :py:meth:`ssl.SSLContext.set_npn_protocols`.
To disable SSL/TLS, omit *ssl* or specify ``None``.
.. py:method:: serve_forever()
Runs server and processes incoming requests forever.
.. py:class:: BaseRequestHandler(http2, stream_id)
The class is used to handle the single HTTP/2 stream. By default,
it does not nothing. It must be subclassed to handle each event
callback method.
The first callback method invoked is :py:meth:`on_headers()`. It is
called when HEADERS frame, which includes request header fields, is
arrived.
If request has request body, :py:meth:`on_data()` is invoked for
each chunk of received data chunk.
When whole request is received, :py:meth:`on_request_done()` is
invoked.
When stream is closed, :py:meth:`on_close()` is called.
The application can send response using :py:meth:`send_response()`
method. It can be used in :py:meth:`on_headers()`,
:py:meth:`on_data()` or :py:meth:`on_request_done()`.
The application can push resource using :py:meth:`push()` method.
It must be used before :py:meth:`send_response()` call.
A :py:class:`BaseRequestHandler` has the following instance
variables:
.. py:attribute:: client_address
Contains a tuple of the form ``(host, port)`` referring to the
client's address.
.. py:attribute:: stream_id
Stream ID of this stream
.. py:attribute:: scheme
Scheme of the request URI. This is a value of ``:scheme``
header field.
.. py:attribute:: method
Method of this stream. This is a value of ``:method`` header
field.
.. py:attribute:: host
This is a value of ``:authority`` or ``host`` header field.
.. py:attribute:: path
This is a value of ``:path`` header field.
.. py:attribute:: headers
Request header fields.
A :py:class:`BaseRequestHandler` has the following methods:
.. py:method:: on_headers()
Called when request HEADERS is arrived. By default, this method
does nothing.
.. py:method:: on_data(data)
Called when a chunk of request body *data* is arrived. This
method will be called multiple times until all data are
received. By default, this method does nothing.
.. py:method:: on_request_done()
Called when whole request was received. By default, this method
does nothing.
.. py:method:: on_close(error_code)
Called when stream is about to close. The *error_code*
indicates the reason of closure. If it is ``0``, the stream is
going to close without error.
.. py:method:: send_response(status=200, headers=None, body=None)
Send response. The *status* is HTTP status code. The *headers*
is additional response headers. The *:status* header field will
be appended by the library. The *body* is the response body.
It could be ``None`` if response body is empty. Or it must be
instance of either ``str``, ``bytes``, :py:class:`io.IOBase` or
callable, called body generator, which takes one parameter,
size. The body generator generates response body. It can pause
generation of response so that it can wait for slow backend data
generation. When invoked, it should return tuple, byte string
at most size length and flag. The flag is either
:py:data:`DATA_OK`, :py:data:`DATA_EOF` or
:py:data:`DATA_DEFERRED`. For non-empty byte string and it is
not the last chunk of response, :py:data:`DATA_OK` must be
returned as flag. If this is the last chunk of the response
(byte string could be ``None``), :py:data:`DATA_EOF` must be
returned as flag. If there is no data available right now, but
additional data are anticipated, return tuple (``None``,
:py:data:`DATA_DEFERRD`). When data arrived, call
:py:meth:`resume()` and restart response body transmission.
Only the body generator can pause response body generation;
instance of :py:class:`io.IOBase` must not block.
If instance of ``str`` is specified as *body*, it will be
encoded using UTF-8.
The *headers* is a list of tuple of the form ``(name,
value)``. The ``name`` and ``value`` can be either byte string
or unicode string. In the latter case, they will be encoded
using UTF-8.
Raises the exception if any error occurs.
.. py:method:: push(path, method='GET', request_headers=None, status=200, headers=None, body=None)
Push a specified resource. The *path* is a path portion of
request URI for this resource. The *method* is a method to
access this resource. The *request_headers* is additional
request headers to access this resource. The ``:scheme``,
``:method``, ``:authority`` and ``:path`` are appended by the
library. The ``:scheme`` and ``:authority`` are inherited from
request header fields of the associated stream.
The *status* is HTTP status code. The *headers* is additional
response headers. The ``:status`` header field is appended by
the library. The *body* is the response body. It has the same
semantics of *body* parameter of :py:meth:`send_response()`.
The headers and request_headers are a list of tuple of the form
``(name, value)``. The ``name`` and ``value`` can be either byte
string or unicode string. In the latter case, they will be
encoded using UTF-8.
Returns an instance of ``RequestHandlerClass`` specified in
:py:class:`HTTP2Server` constructor for the pushed resource.
Raises the exception if any error occurs.
.. py:method:: resume()
Signals the restarting of response body transmission paused by
``DATA_DEFERRED`` from the body generator (see
:py:meth:`send_response()` about the body generator). It is not
an error calling this method while response body transmission is
not paused.
.. py:data:: DATA_OK
``DATA_OK`` indicates non empty data is generated from body generator.
.. py:data:: DATA_EOF
``DATA_EOF`` indicates the end of response body.
.. py:data:: DATA_DEFERRED
``DATA_DEFERRED`` indicates that data are not available right now
and response should be paused.
The following example illustrates :py:class:`HTTP2Server` and
:py:class:`BaseRequestHandler` usage:
.. code-block:: python
#!/usr/bin/env python
import io, ssl
import nghttp2
class Handler(nghttp2.BaseRequestHandler):
def on_headers(self):
self.push(path='/css/style.css',
request_headers = [('content-type', 'text/css')],
status=200,
body='body{margin:0;}')
self.send_response(status=200,
headers = [('content-type', 'text/plain')],
body=io.BytesIO(b'nghttp2-python FTW'))
ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
ctx.options = ssl.OP_ALL | ssl.OP_NO_SSLv2 | ssl.OP_NO_SSLv3
ctx.load_cert_chain('server.crt', 'server.key')
# give None to ssl to make the server non-SSL/TLS
server = nghttp2.HTTP2Server(('127.0.0.1', 8443), Handler, ssl=ctx)
server.serve_forever()
The following example illustrates HTTP/2 server using asynchronous
response body generation. This is simplified reverse proxy:
.. code-block:: python
#!/usr/bin/env python
import ssl
import os
import urllib
import asyncio
import io
import nghttp2
@asyncio.coroutine
def get_http_header(handler, url):

Remember that we have not get stream ID when we submit HTTP request
using `nghttp2_submit_request()`. Since nghttp2 library reorders the
request based on priority and stream ID must be monotonically
increased, the stream ID is not assigned just before transmission.
The one of the purpose of this callback is get the stream ID assigned
to the frame. First we check that the frame is HEADERS frame. Since
HEADERS has several meanings in HTTP/2.0, we check that it is request
HEADERS (which means that the first HEADERS frame to create a stream).
The assigned stream ID is ``frame->hd.stream_id``. Recall that we
passed ``stream_data`` in the *stream_user_data* parameter of
`nghttp2_submit_request()` function. We can get it using
`nghttp2_session_get_stream_user_data()` function. To really sure that
this HEADERS frame is the request HEADERS we have queued, we check
that ``session_data->stream_data`` and ``stream_data`` returned from
`nghttp2_session_get_stream_user_data()` are pointing the same
location. In this example program, we just only uses 1 stream, it is
unnecessary to compare them, but real applications surely deal with
multiple streams, and *stream_user_data* is very handy to identify
which HEADERS we are seeing in the callback. Therefore we just show
how to use it here.

Tutorial: HPACK API
===================
In this tutorial, we describe basic use of HPACK API in nghttp2
library. We briefly describe APIs for deflating and inflating header
fields. The example of using these APIs are presented as complete
source code `deflate.c`_.
Deflating (encoding) headers
----------------------------
First we need to initialize :type:`nghttp2_hd_deflater` object using
`nghttp2_hd_deflate_new()` function::
int nghttp2_hd_deflate_new(nghttp2_hd_deflater **deflater_ptr,
size_t deflate_hd_table_bufsize_max);
This function allocates :type:`nghttp2_hd_deflater` object and
initializes it and assigns its pointer to ``*deflater_ptr`` passed by
parameter. The *deflate_hd_table_bufsize_max* is the upper bound of
header table size the deflater will use. This will limit the memory
usage in deflater object for dynamic header table. If you doubt, just
specify 4096 here, which is the default upper bound of dynamic header
table buffer size.
To encode header fields, `nghttp2_hd_deflate_hd()` function::
ssize_t nghttp2_hd_deflate_hd(nghttp2_hd_deflater *deflater,
uint8_t *buf, size_t buflen,
const nghttp2_nv *nva, size_t nvlen);
The *deflater* is the deflater object initialized by
`nghttp2_hd_deflate_new()` function described above. The *buf* is a
pointer to buffer to store encoded byte string. The *buflen* is
capacity of *buf*. The *nva* is a pointer to :type:`nghttp2_nv`,
which is an array of header fields to deflate. The *nvlen* is the
number of header fields which *nva* contains.
It is important to initialize and assign all members of
:type:`nghttp2_nv`. If a header field should not be inserted in
dynamic header table for a security reason, set
:macro:`NGHTTP2_NV_FLAG_NO_INDEX` flag in :member:`nghttp2_nv.flags`.
`nghttp2_hd_deflate_hd()` processes all headers given in *nva*. The
*nva* must include all request or response header fields to be sent in
one HEADERS (or optionally following (multiple) CONTINUATION
frame(s)). The *buf* must have enough space to store the encoded
result. Otherwise, the function will fail. To estimate the upper
bound of encoded result, use `nghttp2_hd_deflate_bound()` function::
size_t nghttp2_hd_deflate_bound(nghttp2_hd_deflater *deflater,
const nghttp2_nv *nva, size_t nvlen);
Pass this function with the same paramters *deflater*, *nva* and
*nvlen* which will be passed to `nghttp2_hd_deflate_hd()`.
The subsequent call of `nghttp2_hd_deflate_hd()` will use current
encoder state and perform differential encoding which is the
fundamental compression gain for HPACK.
Once `nghttp2_hd_deflate_hd()` fails, it cannot be undone and its
further call with the same deflater object shall fail. So it is very
important to use `nghttp2_hd_deflate_bound()` to know the required
size of buffer.
To delete :type:`nghttp2_hd_deflater` object, use `nghttp2_hd_deflate_del()`
function.
Inflating (decoding) headers
----------------------------
We use :type:`nghttp2_hd_inflater` object to inflate compressed header
data. To initialize the object, use `nghttp2_hd_inflate_new()`::
int nghttp2_hd_inflate_new(nghttp2_hd_inflater **inflater_ptr);
To inflate header data, use `nghttp2_hd_inflate_hd()` function::
ssize_t nghttp2_hd_inflate_hd(nghttp2_hd_inflater *inflater,
nghttp2_nv *nv_out, int *inflate_flags,
uint8_t *in, size_t inlen, int in_final);
The *inflater* is the inflater object initialized above. The *nv_out*
is a pointer to :type:`nghttp2_nv` to store the result. The *in* is a
pointer to input data and *inlen* is its length. The caller is not
required to specify whole deflated header data to *in* at once. It
can call this function multiple times for portion of the data in
streaming way. If *in_final* is nonzero, it tells the function that
the passed data is the final sequence of deflated header data. The
*inflate_flags* is output parameter and successful call of this
function stores a set of flags in it. It will be described later.
This function returns when each header field is inflated. When this
happens, the function sets :macro:`NGHTTP2_HD_INFLATE_EMIT` flag to
*inflate_flag* parameter and header field is stored in *nv_out*. The
return value indicates the number of data read from *in* to processed
so far. It may be less than *inlen*. The caller should call the
function repeatedly until all data are processed by adjusting *in* and
*inlen* with the processed bytes.
If *in_final* is nonzero and all given data was processed, the
function sets :macro:`NGHTTP2_HD_INFLATE_FINAL` flag to
*inflate_flag*. If the caller sees this flag set, call
`nghttp2_hd_inflate_end_headers()` function.
If *in_final* is zero and :macro:`NGHTTP2_HD_INFLATE_EMIT` flag is not
set, it indicates that all given data was processed. The caller is
required to pass subsequent data.
It is important to note that the function may produce one or more
header fields even if *inlen* is 0 when *in_final* is nonzero, due to
differential encoding.
The example use of `nghttp2_hd_inflate_hd()` is shown in
`inflate_header_block()` function in `deflate.c`_.
To delete :type:`nghttp2_hd_inflater` object, use `nghttp2_hd_inflate_del()`
function.

note that nghttp2 itself does not depend on libevent.
First we create a setup routine for libevent and OpenSSL in the functions
``main()`` and ``run()``. One thing in there you should look at, is the setup
of the NPN callback. The NPN callback is used for the server to advertise
which application protocols the server supports to a client. In this example
program, when creating ``SSL_CTX`` object, we store the application protocol
name in the wire format of NPN in a statically allocated buffer. This is safe
because we only create one ``SSL_CTX`` object in the program's entire life
time::

Since we are creating a server and uses options, the nghttp2 session
object is created using `nghttp2_session_server_new2()` function. We
registers five callbacks for nghttp2 session object. We'll talk about
these callbacks later. Our server only speaks HTTP/2. In this case,
we use `nghttp2_option_set_recv_client_preface()` to make
:type:`nghttp2_session` object handle client connection preface, which
saves some lines of application code.
We check that the received byte string matches
:macro:`NGHTTP2_CLIENT_CONNECTION_HEADER`. When they match, the
connection state is ready for starting HTTP/2.0 communication. First
we change the callback functions for the bufferevent object. We use
same ``eventcb`` as before. But we specify new ``readcb`` and
``writecb`` function to handle HTTP/2.0 communication. We describe
these 2 functions later.

a server connection header in ``send_server_connection_header()``::
