<h1>
pathod
<small>A pathological web daemon.</small>
</h1>
</div>
<p>Pathod is a pathological HTTP daemon designed to let you craft almost any
conceivable HTTP response, including ones that creatively violate the
standards. HTTP responses are specified using a <a href="/docs/language">small,
terse language</a>, which pathod shares with its evil twin <a
href="/docs/pathoc">pathoc</a>. </p>
<section>
<div class="page-header">
<h1>Getting started</h1>
</div>
<p> To start playing with pathod, simply fire up the daemon: </p>
<pre class="terminal">./pathod</pre>
<p>By default, the service listens on port 9999 of localhost. Pathod's
documentation is self-hosting, and the pathod daemon exposes an interface that
lets you play with the specifciation language, preview what responses and
requests would look like on the wire, and view internal logs. To access all of
this, just fire up your browser, and point it to the following URL:</p>
<pre class="example">http://localhost:9999</pre>
<p>The default crafting anchor point is the path <b>/p/</b>. Anything after
this URL prefix is treated as a response specifier. So, hitting the following
URL will generate an HTTP 200 response with 100 bytes of random data:</p>
<pre class="example">http://localhost:9999/p/200:b@100</pre>
<p>See the <a href="/docs/language">language documentation</a> to get (much)
fancier. The pathod daemon also takes a range of configuration options. To view
those, use the command-line help:</p>
<pre class="terminal">./pathod --help</pre>
</section>
<section>
<div class="page-header">
<h1>Anchors</h1>
</div>
<p>Anchors provide an alternative to specifying the response in the URL.
Instead, you attach a response to a pre-configured anchor point, specified with
a regex. When a URL matching the regex is requested, the specified response is
served.</p>
<pre class="terminal">./pathod -a "/foo=200"</pre>
<p>Here, "/foo" is ithe regex specifying the anchor path, and the part after
the "=" is a response specifier.</p>
</section>
<section>
<div class="page-header">
<h1>File Access</h1>
</div>
<p>There are two operators in the <a href="/docs/language">language</a> that
load contents from file - the <b>+</b> operator to load an entire request
specification from file, and the <b>&gt;</b> value specifier. In pathod, both
of these operators are restricted to a directory specified at startup, or
disabled if no directory is specified:</p>
<pre class="terminal">./pathod -d ~/staticdir"</pre>
</section>
<section>
<div class="page-header">
<h1>Internal Error Responses</h1>
</div>
<p>Pathod uses the non-standard 800 response code to indicate internal
errors, to distinguish them from crafted responses. For example, a request
to:</p>
<pre class="example">http://localhost:9999/p/foo</pre>
<p>... will return an 800 response because "foo" is not a valid page
specifier.</p>
</section>
<section>
<div class="page-header">
<h1>API</h1>
</div>
<p>pathod exposes a simple API, intended to make it possible to drive and
inspect the daemon remotely for use in unit testing and the like. </p>
<table class="table table-bordered">
<tbody >
<tr>
<td>
/api/clear_log
</td>
<td>
A POST to this URL clears the log buffer.
</td>
</tr>
<tr>
<td>
/api/info
</td>
<td>
Basic version and configuration info.
</td>
</tr>
<tr>
<td>
/api/log
</td>
<td>
Returns the current log buffer. At the moment the buffer size is 500 entries -
when the log grows larger than this, older entries are discarded. The returned
data is a JSON dictionary, with the form:
<pre>{ 'log': [ ENTRIES ] } </pre>
You can preview the JSON data returned for a log entry through the built-in web
interface.
