<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>
</ul>
<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(&amp;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
hello_world(const struct aisl_evt *evt, void *p_ctx)
{
AislStream s;
const char html[] =
"&lt;html&gt;"
"&lt;head&gt;"
"&lt;title&gt;Hello World&lt;/title&gt;"
"&lt;/head&gt;"
"&lt;body&gt;"
"&lt;h1&gt;Hello World&lt;/h1&gt;"
"&lt;p&gt;Powered by AISL&lt;/p&gt;"
"&lt;/body&gt;"
"&lt;/html&gt;";
if (evt-&gt;code != AISL_EVENT_STREAM_REQUEST)
return;
s = evt-&gt;source;
if (aisl_response(s, AISL_HTTP_OK, sizeof (html)-1) == AISL_SUCCESS) {
if (aisl_write(s, html, sizeof (html)-1) != -1) {
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" />
<h3 id="getting-advanced">Getting advanced</h3>
<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.

<ul>
<li><b>instance</b> — a pointer to an <a href="#AislInstance">AislInstance</a>.</li>
</ul>
<p class="content-node">RETURN VALUE</p>
<ul>
<li><a href="#AISL_SUCCESS">AISL_SUCCESS</a> — if some event was triggered</li>

<p>To preserve CPU time it is recommended to add a delay between
<a href="#aisl_run_cycle">aisl_run_cycle</a> calls, at least if anything but
<a href="#AISL_SUCCESS">AISL_SUCCESS</a> has been returned. You may want to
use <a href="#aisl_sleep">aisl_sleep</a> for this.</p>
