<div class="refsect3">
<a name="udisks-modular-design"></a><h4>UDisks modular approach</h4>
<p>UDisks functionality can be extended by modules. It's not a fully
pluggable system as we know it, in this case modules are almost integral
parts of the source tree. Meaning that modules are free to use whatever
internal objects they need as there is no universal module API (or a
translation layer).</p>
<p>This fact allows us to stay code-wise simple and transparent. It also means
that there's no support for out-of-the-tree modules and care must be taken
when changing UDisks internals. As a design decision, for sake of simplicity,
once modules are loaded they stay active until the daemon exits (this may be
a subject to change in the future).</p>
<p>The primary motivation for this was to keep the daemon low on resource
footprint for basic usage (typically desktop environments) and only
activating the extended functionality when needed (e.g. enterprise storage
applications). As the extra information comes in form of additional D-Bus
objects and interfaces, no difference should be observed by legacy clients.</p>
</div>
<div class="refsect3">
<a name="udisks-modular-design-dbus"></a><h4>D-Bus interface extensibility</h4>
<p>The modular approach is fairly simple, there are basically two primary ways
of extending the D-Bus API:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>by attaching custom interfaces to existing objects (limited to block and
drive objects for the moment)</p></li>
<li class="listitem"><p>by exporting objects of its own type directly in the object manager root</p></li>
</ul></div>
<p>Besides that there are several other ways of extensibility such as attaching
custom interfaces on the master /org/freedesktop/UDisks2/Manager object.</p>
</div>
<div class="refsect3">
<a name="udisks-modular-activation"></a><h4>Modules activation</h4>
<p>The UDisks daemon constructs a <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleManager" title="UDisksModuleManager"><span class="type">UDisksModuleManager</span></a> singleton acting as
a manager. This object tracks module usage and takes care of its activation.</p>
<p>By default, module manager is constructed on daemon startup but module
loading is delayed until requested. This can be overriden by the
--force-load-modules and --disable-modules commandline switches that makes
modules loaded right on startup or never loaded respectively.</p>
<p>Upon successful activation, the "modules-ready" property on the <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleManager" title="UDisksModuleManager"><span class="type">UDisksModuleManager</span></a>
instance is set to <a href="../glib/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a>. Any daemon objects watching this property are
responsible for performing "coldplug" on their exported objects to assure
modules would pick up the devices they're interested in. See e.g.
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObjectNewFunc" title="UDisksModuleObjectNewFunc ()"><code class="function">UDisksModuleObjectNewFunc()</code></a> to see how device binding works for
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObject" title="UDisksModuleObject"><span class="type">UDisksModuleObject</span></a>.</p>
<p>Modules are in fact separate shared objects (.so) that are loaded from the
"$(libdir)/udisks2/modules" path (usually "/usr/lib/udisks2/modules"). No
extra or service files are needed, the directory is enumerated and all files
are attempted to be loaded.</p>
<p>Clients are supposed to call the org.freedesktop.UDisks2.Manager.EnableModules()
D-Bus method as a "greeter" call. Please note that from asynchronous nature
of uevents and the way modules are processing them the extra D-Bus interfaces
may not be available right after this method call returns.</p>
</div>
<div class="refsect3">
<a name="udisks-modular-api"></a><h4>Module API</h4>
<p>The (strictly internal) module API is simple - only a couple of functions
are needed. The following text contains brief description of individual
parts of the module API with further links to detailed description within
this API reference book.</p>
<p>The <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleManager" title="UDisksModuleManager"><span class="type">UDisksModuleManager</span></a> first loads all module entry functions, i.e.
symbols defined in the public facing header "udisksmoduleiface.h". Only
those symbols should be exported from each module. The header file is only
meant to be compiled in modules, not the daemon. If any of the symbols is
missing in the module library, the whole module is skipped.</p>
<p>Once module symbols are resolved, module manager activates each module by
calling <code class="function">udisks_module_init()</code> on it. The returned so-called "state" pointer
is stored in the <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleManager" title="UDisksModuleManager"><span class="type">UDisksModuleManager</span></a> and can be later retrieved by calling
the <a class="link" href="udisks2-UDisksModuleManager.html#udisks-module-manager-get-module-state-pointer" title="udisks_module_manager_get_module_state_pointer ()"><code class="function">udisks_module_manager_get_module_state_pointer()</code></a> method. This is typically
used further in the module code to retrieve and store module-specific runtime
data.</p>
<p>Every one of the "udisksmoduleiface.h" header file symbols has its counterpart
defined in the "udisksmoduleifacetypes.h" header file in form of function
pointers. Those are used internally for symbol resolving purposes. However,
they also carry detailed documentation. For illustration purposes, let's
call these symbol pairs the "module setup entry functions". See
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleIfaceSetupFunc" title="UDisksModuleIfaceSetupFunc ()"><span class="type">UDisksModuleIfaceSetupFunc</span></a>, <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObjectNewSetupFunc" title="UDisksModuleObjectNewSetupFunc ()"><span class="type">UDisksModuleObjectNewSetupFunc</span></a> and
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleNewManagerIfaceSetupFunc" title="UDisksModuleNewManagerIfaceSetupFunc ()"><span class="type">UDisksModuleNewManagerIfaceSetupFunc</span></a> for reference. These however are
essentially auxiliary symbols only described for demonstrating the big
picture; for the useful part of the module API please read on.</p>
<p>Every module setup entry function (besides the very simple <code class="function">udisks_module_init()</code>)
returns an array of setup structures or functions, containing either none
(NULL result), one or more elements. The result is then mixed by
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleManager" title="UDisksModuleManager"><span class="type">UDisksModuleManager</span></a> from all modules and separate lists are created for
each kind of UDisks way of extension. Such lists are then used in the daemon
code at appropriate places, sequentially calling elements from the lists to
obtain data or objects that are then typically exported on D-Bus.</p>

<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObjectNewFunc" title="UDisksModuleObjectNewFunc ()"><span class="type">UDisksModuleObjectNewFunc</span></a> and <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleNewManagerIfaceFunc" title="UDisksModuleNewManagerIfaceFunc ()"><span class="type">UDisksModuleNewManagerIfaceFunc</span></a> definitions

<p>This is an another way of extending UDisks functionality. Objects in this
scope are meant to be of virtual kind and are pretty flexible - not
necessarily bound to any block device or perhaps representing a group of
resources. For illustration this kind of object may represent e.g. a RAID
array comprised of several block devices, all devices of the same kind such
as loop devices or any higher level representation of something else.</p>
<p>This function may be called quite often, for nearly any uevent received.
It's done this way for broad flexibility and to give a chance to
<a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObjectNewFunc" title="UDisksModuleObjectNewFunc ()"><span class="type">UDisksModuleObjectNewFunc</span></a> functions to claim any device needed.</p>
<p>Every <a href="../gio/GDBusObjectSkeleton.html#GDBusObjectSkeleton-struct"><span class="type">GDBusObjectSkeleton</span></a> can claim one or more devices and UDisks
automatically manages uevent routing and instance lifecycle. A hierarchy of
claimed devices is maintained for the combination of particular module and

<a class="link" href="UDisksLinuxProvider.html" title="UDisksLinuxProvider"><span class="type">UDisksLinuxProvider</span></a> and is strictly internal. Every module can provide

<div class="orderedlist"><ol class="orderedlist" type="1">

 is already claimed by existing <a href="../gio/GDBusObjectSkeleton.html#GDBusObjectSkeleton-struct"><span class="type">GDBusObjectSkeleton</span></a>
 instance for the current <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObjectNewFunc" title="UDisksModuleObjectNewFunc ()"><span class="type">UDisksModuleObjectNewFunc</span></a>, it is guaranteed
 that only that instance will receive further uevents for the particular
 <em class="parameter"><code>device</code></em>
. This is done by calling the <a class="link" href="udisks2-UDisksModuleManager.html#udisks-module-object-process-uevent" title="udisks_module_object_process_uevent ()"><code class="function">udisks_module_object_process_uevent()</code></a>
 method of the <a class="link" href="udisks2-UDisksModuleManager.html#UDisksModuleObject" title="UDisksModuleObject"><span class="type">UDisksModuleObject</span></a> interface. Depending on the returning
 value the device is either kept claimed by the object or removed. When
 last claimed device has been removed from the instance, it is
 automatically destroyed. In either case no further processing is done
 at this cycle to prevent creating new bogus instances for a <em class="parameter"><code>device</code></em>

 that has just given up.</p></li>
<li class="listitem"><p>In case the <em class="parameter"><code>device</code></em>
 is not claimed by any existing <a href="../gio/GDBusObjectSkeleton.html#GDBusObjectSkeleton-struct"><span class="type">GDBusObjectSkeleton</span></a>

 on the return value of the function called. If it returns a new
 <a href="../gio/GDBusObjectSkeleton.html#GDBusObjectSkeleton-struct"><span class="type">GDBusObjectSkeleton</span></a> instance, it also indicates to <a class="link" href="UDisksLinuxProvider.html" title="UDisksLinuxProvider"><span class="type">UDisksLinuxProvider</span></a>
 that it claims the device. The <a class="link" href="UDisksLinuxProvider.html" title="UDisksLinuxProvider"><span class="type">UDisksLinuxProvider</span></a> then registers the
 value with the current function and keeps track of it. If it returns
 <a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, it inidcates that the current function is not interested in this
 kind of device.</p></li>
</ol></div>
<p>It's guaranteed that existing <a href="../gio/GDBusObjectSkeleton.html#GDBusObjectSkeleton-struct"><span class="type">GDBusObjectSkeleton</span></a> instances will receive
uevents for devices they took and creating a new instance will take place
only if the event was not processed by any of them.</p>
