<p>
A Python package is a collection of modules that provide to the user a certain
functionality. If you're not familiar on how to create packages, a good
introduction to them is provided in the
<a href="http://www.python.org/doc/current/tut/node8.html">
Python Tutorial</a>.</p>
<p>
But we are wrapping C++ code, using Boost.Python. How can we provide a nice
package interface to our users? To better explain some concepts, let's work
with an example.</p>
<p>
We have a C++ library that works with sounds: reading and writing various
formats, applying filters to the sound data, etc. It is named (conveniently)
<tt>sounds</tt>. Our library already has a neat C++ namespace hierarchy, like so: </p>
<code><pre>
<span class=identifier>sounds</span><span class=special>::</span><span class=identifier>core
</span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>io
</span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>filters
</span></pre></code>
<p>
We would like to present this same hierarchy to the Python user, allowing him
to write code like this:</p>
<code><pre>
<span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters
</span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters</span><span class=special>.</span><span class=identifier>echo</span><span class=special>(...) </span>##<span class=identifier>echo </span><span class=identifier>is </span><span class=identifier>a </span><span class=identifier>C</span><span class=special>++ </span><span class=identifier>function
</span></pre></code>
<p>
The first step is to write the wrapping code. We have to export each module
separately with Boost.Python, like this:</p>
<code><pre>
<span class=comment>/* file core.cpp */
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>core</span><span class=special>)
{
/* </span><span class=keyword>export </span><span class=identifier>everything </span><span class=identifier>in </span><span class=identifier>the </span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>core </span><span class=keyword>namespace </span><span class=special>*/
...
}
/* </span><span class=identifier>file </span><span class=identifier>io</span><span class=special>.</span><span class=identifier>cpp </span><span class=special>*/
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>io</span><span class=special>)
{
/* </span><span class=keyword>export </span><span class=identifier>everything </span><span class=identifier>in </span><span class=identifier>the </span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>io </span><span class=keyword>namespace </span><span class=special>*/
...
}
/* </span><span class=identifier>file </span><span class=identifier>filters</span><span class=special>.</span><span class=identifier>cpp </span><span class=special>*/
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>filters</span><span class=special>)
{
/* </span><span class=keyword>export </span><span class=identifier>everything </span><span class=identifier>in </span><span class=identifier>the </span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>filters </span><span class=keyword>namespace </span><span class=special>*/
...
}
</span></pre></code>
<p>
Compiling these files will generate the following Python extensions:
<tt>core.pyd</tt>, <tt>io.pyd</tt> and <tt>filters.pyd</tt>.</p>
<table width="80%" border="0" align="center">
<tr>
<td class="note_box">
<img src="theme/note.gif"></img> The extension <tt>.pyd</tt> is used for python extension modules, which
are just shared libraries. Using the default for your system, like <tt>.so</tt> for
Unix and <tt>.dll</tt> for Windows, works just as well. </td>
</tr>
</table>
<p>
Now, we create this directory structure for our Python package:</p>
<code><pre>
sounds/
__init__.py
core.pyd
filters.pyd
io.pyd
</pre></code><p>
The file <tt>__init__.py</tt> is what tells Python that the directory <tt>sounds/</tt> is
actually a Python package. It can be a empty file, but can also perform some
magic, that will be shown later. </p>
<p>
Now our package is ready. All the user has to do is put <tt>sounds</tt> into his
<a href="http://www.python.org/doc/current/tut/node8.html#SECTION008110000000000000000">
PYTHONPATH</a> and fire up the interpreter:</p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>io
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>sound </span><span class=special>= </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>io</span><span class=special>.</span><span class=identifier>open</span><span class=special>(</span><span class=literal>'file.mp3'</span><span class=special>)
&gt;&gt;&gt; </span><span class=identifier>new_sound </span><span class=special>= </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters</span><span class=special>.</span><span class=identifier>echo</span><span class=special>(</span><span class=identifier>sound</span><span class=special>, </span><span class=number>1.0</span><span class=special>)
</span></pre></code>
<p>
Nice heh? </p>
<p>
This is the simplest way to create hierarchies of packages, but it is not very
flexible. What if we want to add a <i>pure</i> Python function to the filters
package, for instance, one that applies 3 filters in a sound object at once?
Sure, you can do this in C++ and export it, but why not do so in Python? You
don't have to recompile the extension modules, plus it will be easier to write
it.</p>
<p>
If we want this flexibility, we will have to complicate our package hierarchy a
little. First, we will have to change the name of the extension modules:</p>
<code><pre>
<span class=comment>/* file core.cpp */
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>_core</span><span class=special>)
{
...
/* </span><span class=keyword>export </span><span class=identifier>everything </span><span class=identifier>in </span><span class=identifier>the </span><span class=identifier>sounds</span><span class=special>::</span><span class=identifier>core </span><span class=keyword>namespace </span><span class=special>*/
}
</span></pre></code>
<p>
Note that we added an underscore to the module name. The filename will have to
be changed to <tt>_core.pyd</tt> as well, and we do the same to the other extension modules.
Now, we change our package hierarchy like so:</p>
<code><pre>
sounds/
__init__.py
core/
__init__.py
_core.pyd
filters/
__init__.py
_filters.pyd
io/
__init__.py
_io.pyd
</pre></code><p>
Note that we created a directory for each extension module, and added a
__init__.py to each one. But if we leave it that way, the user will have to
access the functions in the core module with this syntax: </p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>core</span><span class=special>.</span><span class=identifier>_core
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>core</span><span class=special>.</span><span class=identifier>_core</span><span class=special>.</span><span class=identifier>foo</span><span class=special>(...)
</span></pre></code>
<p>
which is not what we want. But here enters the <tt>__init__.py</tt> magic: everything
that is brought to the <tt>__init__.py</tt> namespace can be accessed directly by the
user. So, all we have to do is bring the entire namespace from <tt>_core.pyd</tt>
to <tt>core/__init__.py</tt>. So add this line of code to <tt>sounds/core/__init__.py</tt>:</p>
<code><pre>
<span class=identifier>from </span><span class=identifier>_core </span><span class=identifier>import </span><span class=special>*
</span></pre></code>
<p>
We do the same for the other packages. Now the user accesses the functions and
classes in the extension modules like before:</p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters</span><span class=special>.</span><span class=identifier>echo</span><span class=special>(...)
</span></pre></code>
<p>
with the additional benefit that we can easily add pure Python functions to
any module, in a way that the user can't tell the difference between a C++
function and a Python function. Let's add a <i>pure</i> Python function,
<tt>echo_noise</tt>, to the <tt>filters</tt> package. This function applies both the
<tt>echo</tt> and <tt>noise</tt> filters in sequence in the given <tt>sound</tt> object. We
create a file named <tt>sounds/filters/echo_noise.py</tt> and code our function:</p>
<code><pre>
<span class=identifier>import </span><span class=identifier>_filters
</span><span class=identifier>def </span><span class=identifier>echo_noise</span><span class=special>(</span><span class=identifier>sound</span><span class=special>):
</span><span class=identifier>s </span><span class=special>= </span><span class=identifier>_filters</span><span class=special>.</span><span class=identifier>echo</span><span class=special>(</span><span class=identifier>sound</span><span class=special>)
</span><span class=identifier>s </span><span class=special>= </span><span class=identifier>_filters</span><span class=special>.</span><span class=identifier>noise</span><span class=special>(</span><span class=identifier>sound</span><span class=special>)
</span><span class=keyword>return </span><span class=identifier>s
</span></pre></code>
<p>
Next, we add this line to <tt>sounds/filters/__init__.py</tt>:</p>
<code><pre>
<span class=identifier>from </span><span class=identifier>echo_noise </span><span class=identifier>import </span><span class=identifier>echo_noise
</span></pre></code>
<p>
And that's it. The user now accesses this function like any other function
from the <tt>filters</tt> package:</p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=identifier>import </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>sounds</span><span class=special>.</span><span class=identifier>filters</span><span class=special>.</span><span class=identifier>echo_noise</span><span class=special>(...)

Thanks to Python's flexibility, you can easily add new methods to a class,
even after it was already created:</p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=keyword>class </span><span class=identifier>C</span><span class=special>(</span><span class=identifier>object</span><span class=special>): </span><span class=identifier>pass
</span><span class=special>&gt;&gt;&gt;
&gt;&gt;&gt; </span>##<span class=identifier>a </span><span class=identifier>regular </span><span class=identifier>function
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>def </span><span class=identifier>C_str</span><span class=special>(</span><span class=identifier>self</span><span class=special>): </span><span class=keyword>return </span><span class=literal>'A C instance!'
</span><span class=special>&gt;&gt;&gt;
&gt;&gt;&gt; </span>##<span class=identifier>now </span><span class=identifier>we </span><span class=identifier>turn </span><span class=identifier>it </span><span class=identifier>in </span><span class=identifier>a </span><span class=identifier>member </span><span class=identifier>function
</span><span class=special>&gt;&gt;&gt; </span><span class=identifier>C</span><span class=special>.</span><span class=identifier>__str__ </span><span class=special>= </span><span class=identifier>C_str
</span><span class=special>&gt;&gt;&gt;
&gt;&gt;&gt; </span><span class=identifier>c </span><span class=special>= </span><span class=identifier>C</span><span class=special>()
&gt;&gt;&gt; </span><span class=identifier>print </span><span class=identifier>c
</span><span class=identifier>A </span><span class=identifier>C </span><span class=identifier>instance</span><span class=special>!
&gt;&gt;&gt; </span><span class=identifier>C_str</span><span class=special>(</span><span class=identifier>c</span><span class=special>)
</span><span class=identifier>A </span><span class=identifier>C </span><span class=identifier>instance</span><span class=special>!
</span></pre></code>
<p>
Yes, Python rox. <img src="theme/smiley.gif"></img></p>
<p>
We can do the same with classes that were wrapped with Boost.Python. Suppose
we have a class <tt>point</tt> in C++:</p>
<code><pre>
<span class=keyword>class </span><span class=identifier>point </span><span class=special>{...};
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>_geom</span><span class=special>)
{
</span><span class=identifier>class_</span><span class=special>&lt;</span><span class=identifier>point</span><span class=special>&gt;(</span><span class=string>&quot;point&quot;</span><span class=special>)...;
}
</span></pre></code>
<p>
If we are using the technique from the previous session, <a href="creating_packages.html">
Creating Packages</a>, we can code directly into <tt>geom/__init__.py</tt>:</p>
<code><pre>
<span class=identifier>from </span><span class=identifier>_geom </span><span class=identifier>import </span><span class=special>*
</span>##<span class=identifier>a </span><span class=identifier>regular </span><span class=identifier>function
</span><span class=identifier>def </span><span class=identifier>point_str</span><span class=special>(</span><span class=identifier>self</span><span class=special>):
</span><span class=keyword>return </span><span class=identifier>str</span><span class=special>((</span><span class=identifier>self</span><span class=special>.</span><span class=identifier>x</span><span class=special>, </span><span class=identifier>self</span><span class=special>.</span><span class=identifier>y</span><span class=special>))
</span>##<span class=identifier>now </span><span class=identifier>we </span><span class=identifier>turn </span><span class=identifier>it </span><span class=identifier>into </span><span class=identifier>a </span><span class=identifier>member </span><span class=identifier>function
</span><span class=identifier>point</span><span class=special>.</span><span class=identifier>__str__ </span><span class=special>= </span><span class=identifier>point_str
</span></pre></code>
<p>
<b>All</b> point instances created from C++ will also have this member function!
This technique has several advantages:</p>
<ul><li>Cut down compile times to zero for these additional functions</li><li>Reduce the memory footprint to virtually zero</li><li>Minimize the need to recompile</li><li>Rapid prototyping (you can move the code to C++ if required without changing the interface)</li></ul><p>
You can even add a little syntactic sugar with the use of metaclasses. Let's
create a special metaclass that &quot;injects&quot; methods in other classes.</p>
<code><pre>
##<span class=identifier>The </span><span class=identifier>one </span><span class=identifier>Boost</span><span class=special>.</span><span class=identifier>Python </span><span class=identifier>uses </span><span class=keyword>for </span><span class=identifier>all </span><span class=identifier>wrapped </span><span class=identifier>classes</span><span class=special>.

</span>##<span class=identifier>inject </span><span class=identifier>some </span><span class=identifier>methods </span><span class=identifier>in </span><span class=identifier>the </span><span class=identifier>point </span><span class=identifier>foo

</span><span class=keyword>return </span><span class=literal>'Point(x=%s, y=%s)' </span><span class=special>% (</span><span class=identifier>self</span><span class=special>.</span><span class=identifier>x</span><span class=special>, </span><span class=identifier>self</span><span class=special>.</span><span class=identifier>y</span><span class=special>)
</span><span class=identifier>def </span><span class=identifier>foo</span><span class=special>(</span><span class=identifier>self</span><span class=special>):
</span><span class=identifier>print </span><span class=literal>'foo!'
</span></pre></code>
<p>
Now let's see how it got:</p>
<code><pre>
<span class=special>&gt;&gt;&gt; </span><span class=identifier>print </span><span class=identifier>point</span><span class=special>()
</span><span class=identifier>Point</span><span class=special>(</span><span class=identifier>x</span><span class=special>=</span><span class=number>10</span><span class=special>, </span><span class=identifier>y</span><span class=special>=</span><span class=number>10</span><span class=special>)
&gt;&gt;&gt; </span><span class=identifier>point</span><span class=special>().</span><span class=identifier>foo</span><span class=special>()
</span><span class=identifier>foo</span><span class=special>!
</span></pre></code>
<p>
Another useful idea is to replace constructors with factory functions:</p>
<code><pre>
<span class=identifier>_point </span><span class=special>= </span><span class=identifier>point
</span><span class=identifier>def </span><span class=identifier>point</span><span class=special>(</span><span class=identifier>x</span><span class=special>=</span><span class=number>0</span><span class=special>, </span><span class=identifier>y</span><span class=special>=</span><span class=number>0</span><span class=special>):
</span><span class=keyword>return </span><span class=identifier>_point</span><span class=special>(</span><span class=identifier>x</span><span class=special>, </span><span class=identifier>y</span><span class=special>)
</span></pre></code>
<p>
In this simple case there is not much gained, but for constructurs with
many overloads and/or arguments this is often a great simplification, again
with virtually zero memory footprint and zero compile-time overhead for
the keyword support.</p>

If you have ever exported a lot of classes, you know that it takes quite a good
time to compile the Boost.Python wrappers. Plus the memory consumption can
easily become too high. If this is causing you problems, you can split the
class_ definitions in multiple files:</p>
<code><pre>
<span class=comment>/* file point.cpp */
</span><span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>point</span><span class=special>.</span><span class=identifier>h</span><span class=special>&gt;
</span><span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>boost</span><span class=special>/</span><span class=identifier>python</span><span class=special>.</span><span class=identifier>hpp</span><span class=special>&gt;
</span><span class=keyword>void </span><span class=identifier>export_point</span><span class=special>()
{
</span><span class=identifier>class_</span><span class=special>&lt;</span><span class=identifier>point</span><span class=special>&gt;(</span><span class=string>&quot;point&quot;</span><span class=special>)...;
}
/* </span><span class=identifier>file </span><span class=identifier>triangle</span><span class=special>.</span><span class=identifier>cpp </span><span class=special>*/
</span><span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>triangle</span><span class=special>.</span><span class=identifier>h</span><span class=special>&gt;
</span><span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>boost</span><span class=special>/</span><span class=identifier>python</span><span class=special>.</span><span class=identifier>hpp</span><span class=special>&gt;
</span><span class=keyword>void </span><span class=identifier>export_triangle</span><span class=special>()
{
</span><span class=identifier>class_</span><span class=special>&lt;</span><span class=identifier>triangle</span><span class=special>&gt;(</span><span class=string>&quot;triangle&quot;</span><span class=special>)...;
}
</span></pre></code>
<p>
Now you create a file <tt>main.cpp</tt>, which contains the <tt>BOOST_PYTHON_MODULE</tt>
macro, and call the various export functions inside it. </p>
<code><pre>
<span class=keyword>void </span><span class=identifier>export_point</span><span class=special>();
</span><span class=keyword>void </span><span class=identifier>export_triangle</span><span class=special>();
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>_geom</span><span class=special>)
{
</span><span class=identifier>export_point</span><span class=special>();
</span><span class=identifier>export_triangle</span><span class=special>();
}
</span></pre></code>
<p>
Compiling and linking together all this files produces the same result as the
usual approach:</p>
<code><pre>
<span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>boost</span><span class=special>/</span><span class=identifier>python</span><span class=special>.</span><span class=identifier>hpp</span><span class=special>&gt;

</span><span class=preprocessor>#include </span><span class=special>&lt;</span><span class=identifier>triangle</span><span class=special>.</span><span class=identifier>h</span><span class=special>&gt;
</span><span class=identifier>BOOST_PYTHON_MODULE</span><span class=special>(</span><span class=identifier>_geom</span><span class=special>)

debugger, so that it loads its own DLL, before you can set the

<a href="http://connect.apple.com/">http://connect.apple.com/</a>).
Under 10.3 get the Xcode Tools v1.0 (also free).
<p>
Python 2.3 is required. The Python that ships with 10.3 is
fine. Under 10.2.8 use these commands to install Python
as a framework:
<pre>./configure --enable-framework
make
make frameworkinstall</pre>
The last command requires root privileges because the target
directory is
<tt>/Library/Frameworks/Python.framework/Versions/2.3</tt>.
However, the installation does not interfere with the Python
version that ships with 10.2.8.
<p>
It is also crucial to increase the <tt>stacksize</tt> before
starting compilations, e.g.:
<pre>limit stacksize 8192k</pre>
If the <tt>stacksize</tt> is too small the build might crash with
internal compiler errors.

<h2><a name="msvcthrowbug"></a>error C2064: term does
not evaluate to a function taking 2 arguments</h2>
<font size="-1"><i>Niall Douglas provides these notes:</i></font><p>
If you see Microsoft Visual C++ 7.1 (MS Visual Studio .NET 2003) issue
an error message like the following it is most likely due to a bug
in the compiler:
<pre>boost\boost\python\detail\invoke.hpp(76):
error C2064: term does not evaluate to a function taking 2 arguments"</pre>
This message is triggered by code like the following:
<pre>#include &lt;boost/python.hpp&gt;
using namespace boost::python;
class FXThread
{
public:
bool setAutoDelete(bool doso) throw();
};
void Export_FXThread()
{
class_< FXThread >("FXThread")
.def("setAutoDelete", &amp;FXThread::setAutoDelete)
;
}
</pre>
The bug is related to the <code>throw()</code> modifier.
As a workaround cast off the modifier. E.g.:
<pre>
.def("setAutoDelete", (bool (FXThread::*)(bool)) &amp;FXThread::setAutoDelete)</pre>
<p>(The bug has been reported to Microsoft.)</p>

<h2><a name="voidptr"></a>How do I handle <tt>void *</tt> conversion?</h2>
<font size="-1"><i>Niall Douglas provides these notes:</i></font><p>
For several reasons Boost.Python does not support <tt>void *</tt> as
an argument or as a return value. However, it is possible to wrap
functions with <tt>void *</tt> arguments or return values using
thin wrappers and the <i>opaque pointer</i> facility. E.g.:
<pre>// Declare the following in each translation unit
struct void_; // Deliberately do not define
BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID(void_);
void *foo(int par1, void *par2);
void_ *foo_wrapper(int par1, void_ *par2)
{
return (void_ *) foo(par1, par2);
}
...

{
def("foo", &amp;foo_wrapper);

<h2><a name="custom_string"></a>How can I automatically
convert my custom string type to and from a Python string?</h2>
<font size="-1"><i>Ralf W. Grosse-Kunstleve provides these
notes:</i></font><p>
Below is a small, self-contained demo extension module that shows
how to do this. Here is the corresponding trivial test:
<pre>import custom_string
assert custom_string.hello() == "Hello world."
assert custom_string.size("california") == 10</pre>
If you look at the code you will find:
<ul>
<li>A custom <tt>to_python</tt> converter (easy):
<tt>custom_string_to_python_str</tt>
<li>A custom lvalue converter (needs more code):
<tt>custom_string_from_python_str</tt>
</ul>
The custom converters are registered in the global Boost.Python
registry near the top of the module initialization function. Once
flow control has passed through the registration code the automatic
conversions from and to Python strings will work in any module
imported in the same process.

<h2><a name="topythonconversionfailed"></a
>Why is my automatic to-python conversion not being found?</h2>
<font size="-1"><i>Niall Douglas provides these notes:</i></font><p>
If you define custom converters similar to the ones
shown above the <tt>def_readonly()</tt> and <tt>def_readwrite()</tt>
member functions provided by <tt>boost::python::class_</tt> for
direct access to your member data will not work as expected.
This is because <tt>def_readonly("bar",&nbsp;&amp;foo::bar)</tt> is
equivalent to:
<pre>.add_property("bar", make_getter(&amp;foo::bar, return_internal_reference()))</pre>
Similarly, <tt>def_readwrite("bar",&nbsp;&amp;foo::bar)</tt> is
equivalent to:
<pre>.add_property("bar", make_getter(&amp;foo::bar, return_internal_reference()),
make_setter(&amp;foo::bar, return_internal_reference())</pre>
In order to define return value policies compatible with the
custom conversions replace <tt>def_readonly()</tt> and
<tt>def_readwrite()</tt> by <tt>add_property()</tt>. E.g.:
<pre>.add_property("bar", make_getter(&amp;foo::bar, return_value_policy&lt;return_by_value&gt;()),
make_setter(&amp;foo::bar, return_value_policy&lt;return_by_value&gt;()))</pre>
<hr>
<h2><a name="threadsupport"></a
>Is Boost.Python thread-aware/compatible with multiple interpreters?</h2>
<font size="-1"><i>Niall Douglas provides these notes:</i></font><p>
The quick answer to this is: no.</p>
<p>
The longer answer is that it can be patched to be so, but it's
complex. You will need to add custom lock/unlock wrapping of every
time your code enters Boost.Python (particularly every virtual
function override) plus heavily modify
<tt>boost/python/detail/invoke.hpp</tt> with custom unlock/lock
wrapping of every time Boost.Python enters your code. You must
furthermore take care to <i>not</i> unlock/lock when Boost.Python
is invoking iterator changes via <tt>invoke.hpp</tt>.</p>
<p>
There is a patched <tt>invoke.hpp</tt> posted on the C++-SIG
mailing list archives and you can find a real implementation of all
the machinery necessary to fully implement this in the TnFOX
project at <a href="http://sourceforge.net/projects/tnfox/"> this
SourceForge project location</a>.</p>

// Data management for potential rvalue conversions from Python to C++
// types. When a client requests a conversion to T* or T&, we
// generally require that an object of type T exists in the source
// Python object, and the code here does not apply**. This implements
// conversions which may create new temporaries of type T. The classic
// example is a conversion which converts a Python tuple to a
// std::vector. Since no std::vector lvalue exists in the Python
// object -- it must be created "on-the-fly" by the converter, and
// which must manage the lifetime of the created object.
//
// Note that the client is not precluded from using a registered
// lvalue conversion to T in this case. In other words, we will
// happily accept a Python object which /does/ contain a std::vector
// lvalue, provided an appropriate converter is registered. So, while
// this is an rvalue conversion from the client's point-of-view, the
// converter registry may serve up lvalue or rvalue conversions for
// the target type.
//
// ** C++ argument from_python conversions to T const& are an
// exception to the rule for references: since in C++, const
// references can bind to temporary rvalues, we allow rvalue
// converters to be chosen when the target type is T const& for some
// T.
namespace boost { namespace python { namespace converter {
// Conversions begin by filling in and returning a copy of this
// structure. The process looks up a converter in the rvalue converter
// registry for the target type. It calls the convertible() function
// of each registered converter, passing the source PyObject* as an
// argument, until a non-null result is returned. This result goes in
// the convertible field, and the converter's construct() function is
// stored in the construct field.
//
// If no appropriate converter is found, conversion fails and the
// convertible field is null. When used in argument conversion for
// wrapped C++ functions, it causes overload resolution to reject the
// current function but not to fail completely. If an exception is
// thrown, overload resolution stops and the exception propagates back
// through the caller.
//
// If an lvalue converter is matched, its convertible() function is
// expected to return a pointer to the stored T object; its
// construct() function will be NULL. The convertible() function of
// rvalue converters may return any non-singular pointer; the actual

// arity that fname can accept.
//
// There are two versions:
//
// 1. BOOST_PYTHON_FUNCTION_OVERLOADS for free functions
