<a name="GstRegistry.description"></a><h2>Description</h2>
<p>
One registry holds the metadata of a set of plugins.
</p>
<p>
<span class="bold"><strong>Design:</strong></span>
</p>
<p>
The <a class="link" href="GstRegistry.html" title="GstRegistry"><span class="type">GstRegistry</span></a> object is a list of plugins and some functions for dealing
with them. Each <a class="link" href="GstPlugin.html" title="GstPlugin"><span class="type">GstPlugin</span></a> is matched 1-1 with a file on disk, and may or may
not be loaded at a given time. There may be multiple <a class="link" href="GstRegistry.html" title="GstRegistry"><span class="type">GstRegistry</span></a> objects,
but the "default registry" is the only object that has any meaning to the
core.
</p>
<p>
The registry file is actually a cache of plugin information. This is
unlike versions prior to 0.10, where the registry file was the primary source
of plugin information, and was created by the gst-register command.
</p>
<p>
The primary source, at all times, of plugin information is each plugin file
itself. Thus, if an application wants information about a particular plugin,
or wants to search for a feature that satisfies given criteria, the primary
means of doing so is to load every plugin and look at the resulting
information that is gathered in the default registry. Clearly, this is a time
consuming process, so we cache information in the registry file. The format
and location of the cache file is internal to gstreamer.
</p>
<p>
On startup, plugins are searched for in the plugin search path. The following
locations are checked in this order:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p>location from --gst-plugin-path commandline option.</p></li>
<li class="listitem"><p>the GST_PLUGIN_PATH environment variable.</p></li>
<li class="listitem"><p>the GST_PLUGIN_SYSTEM_PATH environment variable.</p></li>
<li class="listitem"><p>default locations (if GST_PLUGIN_SYSTEM_PATH is not set). Those
      default locations are:
      <code class="filename">~/.gstreamer-$GST_MAJORMINOR/plugins/</code>
      and <code class="filename">$prefix/libs/gstreamer-$GST_MAJORMINOR/</code>.
    </p></li>
</ul></div>
<p>
The registry cache file is loaded from
<code class="filename">~/.gstreamer-$GST_MAJORMINOR/registry-$ARCH.bin</code> or the
file listed in the GST_REGISTRY env var. One reason to change the registry
location is for testing.
</p>
<p>
For each plugin that is found in the plugin search path, there could be 3
possibilities for cached information:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p>the cache may not contain information about a given file.</p></li>
<li class="listitem"><p>the cache may have stale information.</p></li>
<li class="listitem"><p>the cache may have current information.</p></li>
</ul></div>
<p>
</p>
<p>
In the first two cases, the plugin is loaded and the cache updated. In
addition to these cases, the cache may have entries for plugins that are not
relevant to the current process. These are marked as not available to the
current process. If the cache is updated for whatever reason, it is marked
dirty.
</p>
<p>
A dirty cache is written out at the end of initialization. Each entry is
checked to make sure the information is minimally valid. If not, the entry is
simply dropped.
</p>
<p>
<span class="bold"><strong>Implementation notes:</strong></span>
</p>
<p>
The "cache" and "default registry" are different concepts and can represent
different sets of plugins. For various reasons, at init time, the cache is
stored in the default registry, and plugins not relevant to the current
process are marked with the <a class="link" href="GstPlugin.html#GST-PLUGIN-FLAG-CACHED:CAPS"><code class="literal">GST_PLUGIN_FLAG_CACHED</code></a> bit. These plugins are
removed at the end of initialization.
