<h1>building</h1>
|

|
|
<p>Building the libtorrent python bindings will produce a shared library (DLL)
|
||
|
|
which is a python module that can be imported in a python program.</p>
|
||
|
|
<div class="section" id="building-using-setup-py">
|
||
|
|
<h2>building using setup.py</h2>
|
||
|
|
<p>There is a <tt class="docutils literal">setup.py</tt> shipped with libtorrent that can be used on windows.
|
||
|
|
On windows the setup.py will invoke <tt class="docutils literal">bjam</tt> and assume that you have boost
|
||
|
|
sources at <tt class="docutils literal">$BOOST_PATH</tt>. The resulting executable is self-contained, it does
|
||
|
|
not depend any boost or libtorrent dlls.</p>
|
||
|
|
<p>On other systems, the setup.py is generated by running
|
||
|
|
<tt class="docutils literal">./configure <span class="pre">--enable-python-binding</span></tt>.</p>
|
||
|
|
<p>To build the Python bindings do:</p>
|
||
|
|
<ol class="arabic">
|
||
|
|
<li><p class="first">Run:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
python setup.py build
|
||
|
|
</pre>
|
||
|
|
</li>
|
||
|
|
<li><p class="first">As root, run:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
python setup.py install
|
||
|
|
</pre>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
</div>
|
||
|
|
<div class="section" id="building-using-boost-build">
|
||
|
|
<h2>building using boost build</h2>
|
||
|
|
<p>To set up your build environment, you need to add some settings to your
|
||
|
|
<tt class="docutils literal"><span class="pre">$BOOST_BUILD_PATH/user-config.jam</span></tt>.</p>
|
||
|
|
<p>Make sure your user config contains the following line:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
using python : 2.3 ;
|
||
|
|
</pre>
|
||
|
|
<p>Set the version to the version of python you have installed or want to use. If
|
||
|
|
you've installed python in a non-standard location, you have to add the prefix
|
||
|
|
path used when you installed python as a second option. Like this:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
using python : 2.6 : /usr/bin/python2.6 : /usr/include/python2.6 : /usr/lib/python2.6 ;
|
||
|
|
</pre>
|
||
|
|
<p>The bindings require <em>at least</em> python version 2.2.</p>
|
||
|
|
<p>For more information on how to install and set up boost-build, see the
|
||
|
|
<a class="reference external" href="building.html#step-2-setup-bbv2">building libtorrent</a> section.</p>
|
||
|
|
<p>Once you have boost-build set up, you cd to the <tt class="docutils literal">bindings/python</tt>
|
||
|
|
directory and invoke <tt class="docutils literal">bjam</tt> with the apropriate settings. For the available
|
||
|
|
build variants, see <a class="reference external" href="building.html#step-3-building-libtorrent">libtorrent build options</a>.</p>
|
||
|
|
<p>For example:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
$ bjam dht-support=on boost=source release link=static
|
||
|
|
</pre>
|
||
|
|
<p>On Mac OS X, this will produce the following python module:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
bin/darwin-4.0/release/dht-support-on/link-static/logging-none/threading-multi/libtorrent.so
|
||
|
|
</pre>

|
<div class="section" id="using-libtorrent-in-python">
|
||
|
|
<h1>using libtorrent in python</h1>
|
||
|
|
<p>The python interface is nearly identical to the C++ interface. Please refer to
|
||
|
|
the <a class="reference external" href="manual.html">main library reference</a>. The main differences are:</p>
|
||
|
|
<dl class="docutils">
|
||
|
|
<dt>asio::tcp::endpoint</dt>
|
||
|
|
<dd>The endpoint type is represented as a tuple of a string (as the address) and an int for
|
||
|
|
the port number. E.g. <tt class="docutils literal">('127.0.0.1', 6881)</tt> represents the localhost port 6881.</dd>
|
||
|
|
<dt>libtorrent::time_duration</dt>
|
||
|
|
<dd>The time duration is represented as a number of seconds in a regular integer.</dd>
|
||
|
|
</dl>
|
||
|
|
<p>The following functions takes a reference to a container that is filled with
|
||
|
|
entries by the function. The python equivalent of these functions instead returns
|
||
|
|
a list of entries.</p>
|
||
|
|
<ul class="simple">
|
||
|
|
<li>torrent_handle::get_peer_info</li>
|
||
|
|
<li>torrent_handle::file_progress</li>
|
||
|
|
<li>torrent_handle::get_download_queue</li>
|
||
|
|
<li>torrent_handle::piece_availability</li>
|
||
|
|
</ul>
|
||
|
|
<p><tt class="docutils literal"><span class="pre">create_torrent::add_node()</span></tt> takes two arguments, one string and one integer,
|
||
|
|
instead of a pair. The string is the address and the integer is the port.</p>
|
||
|
|
<p><tt class="docutils literal"><span class="pre">session::set_settings()</span></tt> not only accepts a <tt class="docutils literal">session_settings</tt> object, but also
|
||
|
|
a dictionary with keys matching the names of the members of the <tt class="docutils literal">session_settings</tt> struct.
|
||
|
|
When calling <tt class="docutils literal">set_settings</tt>, the dictionary does not need to have every settings set,
|
||
|
|
keys that are not present, are set to their default value.</p>
|
||
|
|
<p>For backwards compatibility, <tt class="docutils literal"><span class="pre">session::settings()</span></tt> still returns a <tt class="docutils literal">session_settings</tt>
|
||
|
|
struct. To get a python dictionary of the settings, call <tt class="docutils literal"><span class="pre">session::get_settings</span></tt>.</p>
|
||
|
|
<p>For an example python program, see <tt class="docutils literal">client.py</tt> in the <tt class="docutils literal">bindings/python</tt>
|
||
|
|
directory.</p>
|
||
|
|
<p>A very simple example usage of the module would be something like this:</p>
|
||
|
|
<pre class="literal-block">
|
||
|
|
import libtorrent as lt
|
||
|
|
import time

|
||
|
|
ses.listen_on(6881, 6891)
|
||
|
|
|
||
|
|
e = lt.bdecode(open("test.torrent", 'rb').read())
|
||
|
|
info = lt.torrent_info(e)
|
||
|
|
|
||
|
|
h = ses.add_torrent(info, "./", storage_mode=storage_mode_sparse)
|
||
|
|
|
||
|
|
while (not h.is_seed()):
|
||
|
|
s = h.status()
|
||
|
|
|
||
|
|
state_str = ['queued', 'checking', 'downloading metadata', \
|
||
|
|
'downloading', 'finished', 'seeding', 'allocating']
|
||
|
|
print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % \
|
||
|
|
(s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
|
||
|
|
s.num_peers, state_str[s.state])
|
||
|
|

time.sleep(1)
