HTTP Parser
===========
This is a parser for HTTP messages written in C. It parses both requests
and responses. The parser is designed to be used in performance HTTP
applications. It does not make any allocations, it does not buffer data, and
it can be interrupted at anytime. It only requires about 100 bytes of data
per message stream (in a web server that is per connection).
Features:
* No dependencies
* Parses both requests and responses.
* Handles keep-alive streams.
* Decodes chunked encoding.
* Extracts the following data from a message
* header fields and values
* content-length
* request method
* response status code
* transfer-encoding
* http version
* request path, query string, fragment
* message body
Usage
-----
One `http_parser` object is used per TCP connection. Initialize the struct
using `http_parser_init()` and set the callbacks. That might look something
like this:
http_parser *parser = malloc(sizeof(http_parser));
http_parser_init(parser, HTTP_REQUEST);
parser->on_path = my_path_callback;
parser->on_header_field = my_header_field_callback;
parser->data = my_socket;
When data is received on the socket execute the parser and check for errors.
size_t len = 80*1024;
char buf[len];
ssize_t recved;
recved = read(fd, buf, len);
if (recved != 0) // handle error
http_parser_execute(parser, buf, recved);
if (http_parser_has_error(parser)) {
// handle error. usually just close the connection
}
During the `http_parser_execute()` call, the callbacks set in `http_parser`
will be executed. The parser maintains state and never looks behind, so
buffering the data is not necessary. If you need to save certain data for
later usage, you can do that from the callbacks. (You can also `read()` into
a heap allocated buffer to avoid copying memory around if this fits your
application.)
The parser decodes the transfer-encoding for both requests and responses
transparently. That is, a chunked encoding is decoded before being sent to
the on_body callback.
It does not decode the content-encoding (gzip). Not all HTTP applications
need to inspect the body. Decoding gzip is non-neglagable amount of
processing (and requires making allocations). HTTP proxies using this
parser, for example, would not want such a feature.

<h1>libebb</h1>
<p>
libebb is a lightweight HTTP server library for C. It lays the
foundation for writing a web server by providing the socket juggling
and request parsing. By implementing the HTTP/1.1 grammar provided in
RFC2612, libebb understands most most valid HTTP/1.1 connections
(persistent, pipelined, and chunked requests included) and rejects
invalid or malicious requests. libebb supports SSL over HTTP.
</p>
<p>
The library embraces a minimalistic single-threaded evented design.
No control is removed from the user. For example, all allocations are
done through callbacks so that the user might implement in optimal
ways for their specific application. By design libebb is not
thread-safe and all provided callbacks must not block. libebb uses
the <a href="http://libev.schmorp.de/bench.html">high-performance</a>
libev event loop, but does not control it. The user of the library may
start and stop the loop at will, they may attach thier own watchers.
</p>
<p>
libebb depends on POSIX sockets, libev, and optionally GnuTLS.
</p>
<p>
libebb is in the early stages of development and probably contains
many bugs. The API is subject to radical changes. If you're
interested <a href="http://github.com/ry/libebb/tree/master">checkout
the source code</a> and <a
href="http://groups.google.com/group/ebbebb">join the mailing
list</a>. A release will be made when it proves stable.
</p>
<p>libebb is released under <a
href="http://www.gnu.org/licenses/license-list.html#X11License">the
X11 license</a>.</p>
<h2>Usage</h2>
<p>
libebb is a simple API, mostly it is providing callbacks. There are
two types of callbacks that one will work with:
</p>
<ul>
<li>callbacks to allocate and initialize data for libebb. These are
named <code>new_*</code> like <code>new_connection</code> and
<code>new_request</code></li>
<li>callbacks which happen on an event and might provide a pointer to
a chunk of data. These are named <code>on_*</code> like
<code>on_body</code> and <code>on_close</code>.</li>
</ul>
<p>
In libebb there are three important classes: <code>ebb_server</code>,
<code>ebb_connection</code>, and <code>ebb_request</code>.
Each server has many peer connections. Each peer connection may have many
requests.
There are two additional classes <code>ebb_buf</code> and <code>ebb_request_parser</code>
which may or may not be useful.
</p>
<h3><code>ebb_server</code></h3>
<p>
<code>ebb_server</code> represents a single web server listening on a
single port. The user must allocate the structure themselves, then
call <code>ebb_server_init()</code> and provide a libev event loop.
<code>ebb_server_set_secure()</code> will make the server understand
HTTPS connections.
</p>
<p>
After initialized the <code>ebb_server_listen_on_port()</code> can be
called to open the server up to new connections. libebb does not
control the event loop, it is the user's responsibility to start the
event loop (using <code>ev_loop()</code>) after
<code>ebb_server_listen_on_port()</code> is called.
</p>
<p>
To accept connections you must provide the new server with a callback
called <code>new_connection</code>. This callback must return an allocated
and initialized <code>ebb_connection</code> structure.
To set this callback do
</p>
<pre>my_server-&gt;new_connection = my_new_connection_callback;</pre>
<p>
Additional documentation can be found in <code>ebb.h</code>
</p>
<h3><code>ebb_connection</code></h3>
<p>
This structure contains information and callbacks for a single client
connection. It is allocated and initialized through the
<code>new_connection</code> callback in <code>ebb_server</code>.
To initialize a newly allocated <code>ebb_connection</code> use
<code>ebb_connection_init()</code>.
</p>
<p>
After <code>ebb_connection_init()</code> is called a number of
callbacks can be set: <code>new_request</code>, <code>new_buf</code>,
<code>on_timeout</code>, and <code>on_close</code>.
</p>
<p>
When an <code>ebb_connection</code> is returned to an
<code>ebb_server</code>, data is immediately data is read from the
socket. This data must be stored somewhere. Because libebb is
agnostic about allocation decisions, it passes this off to the user in
the form of a callback: <code>connection-&gt;new_buf</code>. This
callback returns a newly allocated and initialized
<code>ebb_buf</code> structure. How much libebb attempts to read from
the socket is determined by how large the returned
<code>ebb_buf</code> structure is. Using <code>new_buf</code> is
optional. By default libebb reads data into a static buffer
(allocated at compile time), writing over it on each read. In many
web server using the static buffer will be sufficent because callbacks
made during the parsing will buffer the data elsewhere. Providing a
<code>new_buf</code> callback is necessary only if you want to save
the raw data coming from the socket.
</p>
<p>
The <code>new_request</code> callback is called at the beginning of a
request. It must return a newly allocated and initialized
<code>ebb_request</code> structure. Because HTTP/1.1 supports <a
href="http://en.wikipedia.org/wiki/HTTP_persistent_connection">peristant</a>
connections, there may be many requests per connection.
</p>
<p>
You may access the file descriptor for the client socket inside the
<code>ebb_connection</code> structure. Writing the response, in valid
HTTP, is the user's responsibility. Remember, requests must be
returned to client in the same order that they were received.
</p>
<p>
A convience function, <coe>ebb_connection_write</code>, is provided
which will write a single string to the peer. You may use
this function or you may write to the file descriptor directly.
</p>
<p>
To close a peer connection use
<code>ebb_connnection_schedule_close()</code>. Because SSL may require
some additional communication to close the connection properly, the
file descriptor cannot be closed immediately. The
<code>on_close</code> callback will be made when the peer socket is
finally closed.
<em>Only once <code>on_close</code> is called may the
user free the <code>ebb_connection</code> structure.</em>
</p>
<h3><code>ebb_request</code></h3>
<p>
This structure provides information about a request. For example,
<code>request-&gt;method == EBB_POST</code> would mean the method of
the request is <code>POST</code>. There are also many callbacks
which can be set to handle data from a request as it is parsed.
</p>
<p>
The <code>on_uri</code> callback and all other
<code>ebb_element_cb</code> callbacks provide pointers to request
data. The annoying thing is they do not necessarily provide a
complete string. This is because the reads from the socket may not
contain an entire request and for efficency libebb does not attempt to
buffer the data. Theoretically, one might receive an
<code>on_uri</code> callback 10 times, each providing just a single
character of the request's URI. See <code>ebb_request_parser.h</code> for
a full list of callbacks that you may provide. (If you don't set them,
they are ignored.)
</p>
<p>
The <code>on_complete</code> callback is called at the end of
each request.
<em>Only once <code>on_complete</code> is called may the
user free the <code>ebb_request</code> structure.</em>
</p>
<h2>Example</h2>
<p>
A simple example is provided in <code>examples/hello_world.c</code>.
