<h2 id="overview">AISL Overview</h2>
|
||
|
|
|
||
|
|
<p>If you are reading this, either you are somehow already familiar with web
|
||
|
|
applications and web servers and you probably used to count them as an
|
||
|
|
independent entities. Indeed, most of the existing web technologies are
|
||
|
|
based on standalone web server and HTTP parser that together provide some
|
||
|
|
programming interface to work with cached in memory and on a hard disk HTTP
|
||
|
|
request. It is not that efficient and sometimes even vulnerable in sence of
|
||
|
|
DDoS attacks.</p>
|
||
|
|
<p>AISL works differently. Using AISL you can create web application
|
||
|
|
that is a web server. It means that developer can keep under control all the
|
||
|
|
workflow of an HTTP stream, by appropriate reactoin on triggered by AISL
|
||
|
|
programmable events, which is a great performance and security advantage.
|
||
|
|
For example, application may want to already start some routines to prepare
|
||
|
|
response, when just first line of the HTTP request like
|
||
|
|
<span class="inline-code">GET /index.html HTTP/1.1</span> was received. Or
|
||
|
|
it may also want to ignore some of the HTTP headers or even full body
|
||
|
|
content to preserve resources and CPU time, if they are unnecessary
|
||
|
|
or even unwelcome.</p>
|
||
|
|
|
||
|
|
<h3 id="features">Features</h3>
|
||
|
|
<ul>
|
||
|
|
<li>Asynchronous event-based engine</li>
|
||
|
|
<li>Lightweight solution: size of the shared C library is just about 38
|
||
|
|
Kbytes.</li>
|
||
|
|
<li>HTTP 1.x support (support of HTTP 2.0 is planned).</li>
|
||
|
|
<li>HTTPS support (using openssl).</li>
|
||
|
|
<li>Free software with open source code.</li>
|
||
|
|
<li><a href="https://creativecommons.org/licenses/by-nd/4.0/" rel="license">CC BY-ND 4.0</a> License.</p>

|
||
|
|
<h3 id="installation">Installation</h3>
|
||
|
|
<p>One can get AISL sources from GitHub at any time. Master branch is always
|
||
|
|
stable. To get the Library follow these steps:</p>
|
||
|
|
<ol>
|
||
|
|
<li>Clone GIT repositroy<code>$ git clone https://github.com/lowenware/aisl.git</code></li>
|
||
|
|
<li>Navigate to cloned folder<code>$ cd aisl</code></li>
|
||
|
|
<li>Compile the library<code>$ make PREFIX=/usr/local LIB_DIR=lib</code>
|
||
|
|
Set <code class="inline">PREFIX</code> to preffered installation path
|
||
|
|
and <code class="inline">LIB_DIR</code> to your system related name of
|
||
|
|
library directory (lib, lib32 or lib64).</li>
|
||
|
|
<li>Install the library<code>$ sudo make install</code></li>
|
||
|
|
<li>Optionaly advanced users may want to build library with one or more
|
||
|
|
options:
|
||
|
|
<code class="inline">AISL_WITH_SSL=0</code> - disable
|
||
|
|
HTTPS support, <code class="inline">AISL_WITH_STRINGIFIERS=0</code> -
|
||
|
|
disable several optional *_to_string functions to preserve library sizea,
|
||
|
|
<code class="inline">AISL_WITH_DEBUG=1</code> - enable library debug
|
||
|
|
output.</li>
|
||
|
|
<li>You may also want to edit (if you have changed
|
||
|
|
<code class="inline">PREFIX</code> or <code class="inline">LIB_DIR</code>)
|
||
|
|
and copy <i>libaisl.pc.example</i> file to <i>/usr/lib/pkgconfig</i>, so
|
||
|
|
<i>pkgconfig</i> could be used to simplify future linking.</li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<h3 id="hello-world">Getting started - Hello World</h3>
|
||
|
|
<p>If you have AISL installed, it is time to try it out with simple
|
||
|
|
`Hello World!` application. Full source code could be found on a
|
||
|
|
<a href="https://github.com/lowenware/aisl/blob/master/examples/hello-world.c">GitHub</a>
|
||
|
|
and the most important steps are highlighted bellow.</p>
|
||
|
|
<p>Include AISL meta-header file to add necessary declarations to you
|
||
|
|
code file. You should never include other AISL header files in to your
|
||
|
|
projects.</p>
|
||
|
|
<code>#include <aisl/aisl.h></code>
|
||
|
|
|
||
|
|
<p>In this example we create one HTTP server without encryption, that will
|
||
|
|
listen to port 8080 on all available network interfaces.</p>
|
||
|
|
<code>struct <a href="#aisl_cfg_srv">aisl_cfg_srv</a>[] srv = {{
|
||
|
|
.host = "0.0.0.0",
|
||
|
|
.port = 8080,
|
||
|
|
.secure = false
|
||
|
|
}};</code>
|
||
|
|
|
||
|
|
<p>To initialize configuration structure we use default values.</p>
|
||
|
|
<code>struct <a href="#aisl_cfg">aisl_cfg</a> cfg = AISL_CFG_DEFAULT;</code>
|
||
|
|
|
||
|
|
<p>An address of the defined servers configuration and their number must be
|
||
|
|
also stored in the structure.</p>
|
||
|
|
<code>cfg.srv = srv;
|
||
|
|
cfg.srv_cnt = sizeof (srv) / sizeof (srv[0]);</code>
|
||
|
|
|
||
|
|
<p>Event handler is a core function of the web application. It should match
|
||
|
|
<a href="#AislCallback">AislCallback</a> prototype and its address also
|
||
|
|
must be stored in the configuration structure before library
|
||
|
|
initialization.</p>
|
||
|
|
<code>cfg.callback = hello_world;</code>
|
||
|

<p>When configuration is ready, it is time to allocate and initialize our
|
||
|
|
<a href="#AislInstance">AislInstance</a> and start application loop.</p>
|
||
|
|
<code>AislInstance aisl;
|
||
|
|
AislStatus status;
|
||
|
|
...
|
||
|
|
if ( (aisl = aisl_new(&cfg)) != NULL ) {
|
||
|
|
/* launch application loop */
|
||
|
|
fprintf(stdout, "Entering main loop\n" );
|
||
|
|
for(;;) {
|
||
|
|
status = aisl_run_cycle(aisl);
|
||
|
|
|
||
|
|
if ( status != AISL_SUCCESS )
|
||
|
|
aisl_sleep(aisl, 500);
|
||
|
|
}
|
||
|
|
aisl_free(aisl);
|
||
|
|
} else {
|
||
|
|
fprintf(stderr, "Failed to initialize AISL\n");
|
||
|
|
}</code>
|
||
|
|
<p>Function <a href="#aisl_run_cycle">aisl_run_cycle</a> being called within
|
||
|
|
a loop does all the core routines of our HTTP server and triggers event callback
|
||
|
|
defined in configuration structure. To avoid unnecessary CPU loading we
|
||
|
|
also execute <a href="#aisl_sleep">aisl_sleep</a> on idle cycles. To
|
||
|
|
release allocated by AISL resources on a runtime we are using
|
||
|
|
<a href="#aisl_sleep">aisl_sleep</a>.</p>
|
||
|
|
|
||
|
|
<p>And finally it is time to define the event handler matching
|
||
|
|
<a href="#AislCallback">AislCallback</a> prototype.</p>
|
||
|
|
<code>static void
|
||
|

if (evt->code != AISL_EVENT_STREAM_REQUEST)
|

return;

aisl_flush(s);
|

return;
|

}
|

|
|
|

aisl_reject(s);
|
||
|
|
(void) p_ctx;
|
||
|
|
}</code>
|
||
|
|
<p>The function is being called by AISL engine on every event, but proceeds
|
||
|
|
only if <a href="#AISL_EVENT_STREAM_REQUEST">AISL_EVENT_STREAM_REQUEST</a>
|
||
|
|
is received. It starts an HTML response stored in <code class="inline">html</code>
|
||
|
|
constant. Make sure you use <code class="inline">sizeof (htmk)-1</code> for
|
||
|
|
content length, to avoid unwanted write of last NULL terminating character
|
||
|
|
of <code class="inline">html</code> string constant.</p>
|
||
|
|
|
||
|
|
<p>To compile the example using GCC and pkgconfig run:</p>
|
||
|
|
<code>$ gcc `pkgconf --libs --cflags libaisl` hello-world.c -o hello-world</code>
|
||
|
|
<p>Or specify paths to installed header files and library manualy:</p>
|
||
|
|
<code>$ -I/usr/local/include -L/usr/local/lib -laisl hello-world.c -o hello-world</code>
|
||
|
|
|
||
|
|
<p>Now execute compiled hello_world binary and open <a href="http://localhost:8080">http://localhost:8080</a> in
|
||
|
|
your browser. If you get any <code class="inline">symbol lookup error</code> on execution attempt,
|
||
|
|
try to specify the path to the library in the environment variable:</p>
|
||
|
|
<code>$ LD_LIBRARY_PATH="/usr/local/lib" ./hello-world</code>
|
||
|
|
<p>The result should look like this:</p>
|
||
|
|
<img src="/aisl/hello-world.jpg" class="shrink-picture" />

<p>Right after this chapter you will find full AISL
|
||
|
|
<a href="#api-reference">API Reference</a> that guides through all the types
|
||
|
|
and functions. The most significant of them you may already know from the
|
||
|
|
<a href="#getting-started">Hello World</a> example. To become an advanced
|
||
|
|
AISL developer, you will need to understand <a href="#AislEvent">events model</a>
|
||
|
|
and <a href="#AislStream">stream concept</a>. The rest of library
|
||
|
|
components carry more auxiliary function.</p>
|
||
|
|
|
||
|
|
<h2 id="api-reference">API Reference</h2>
|
||
|
|
<p>AISL library API has object oriented model. Although C has no objects,
|
||
|
|
it still allows to use transparent data structures to represent classes and
|
||
|
|
functions as methods.</p>
|
||
|
|
<p>Each AISL component has a library specific prefix:</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>Aisl*</b> - for data types (typedefs)</li>
|
||
|
|
<li><b>aisl_*</b> - for functions and structures names</li>
|
||
|
|
<li><b>AISL_*</b> - for constants and macro definitions</li>
|
||
|
|
</ul>
|
||
|
|
<p>Functions, related to some data type (methods), include name of the type in
|
||
|
|
their names, i.e. <code class="inline">AislServer - aisl_server_get_address()</code>.
|
||
|
|
There are two exceptions from this rule though introduced for simplicity and
|
||
|
|
shorter names for the functions being used most often: <a href="#AislInstance">AislInstance</a>
|
||
|
|
and <a href="#AislStream">AislStream</a>.</p>
|
||
|
|
|
||
|
|
<h3 id="AislInstance">Class AislInstance</h3>
|
||
|
|
<p>This class represents library engine, that could be dynamically allocated
|
||
|
|
in memory. It means that you can have several library instances in one application,
|
||
|
|
though you may never meet a real use case for this.</p>
|
||
|
|
<p>Every instance may handle several independent HTTP servers running on
|
||
|
|
different network sockets and manages SSL certificates and communication with
|
||
|
|
clients.</p>
|
||
|
|
<p>Each instance must be configured with proper parameters stored in
|
||
|
|
<a href="#aisl_cfg">aisl_cfg</a> data structure with at least one HTTP
|
||
|
|
server and event handler matching <a href="#AislCallback">AislCallback</a>
|
||
|
|
prototype.
