<h1>Building, Configuring and Testing Python XPCOM Package</h1>
|
|
<p>This document attempts to explain how to build, configure and test the
|
|
Python XPCOM Package. This document assumes you have already successfully
|
|
built
|
|
Mozilla from source and your environment is currently set up for such a build -
|
|
see the <a href="http://www.mozilla.org/build/">Mozilla build documentation</a>
|
|
for more information.</p>

<h2><a name="ConfigureTheEnvironment">Configuring your Environment</a></h2>
|
|
<p>In addition to the existing environment requirements for building Mozilla itself, the
|
|
Python XPCOM package has the following requirements:</p>
|
|
<ul>
|
|
<li>
|
|
<a name="MozillaDirectory"><b>Mozilla Directory</b></a><b> - </b>Ensure the Mozilla
|
|
<i> bin</i> directory is on your PATH
|
|
(LD_LIBRARY_PATH
|
|
on Unix) so Python can locate the <i> xpcom.dll</i> module needed for
|
|
core XPCOM services.</li>
|
|
<li><a name="PYTHONPATH"><b>PYTHONPATH</b></a> - <tt>PYTHONPATH</tt> needs to be set appropriately. Ensure
|
|
the parent to this <i>xpcom</i> directory is on your path so "import
|
|
xpcom" locates this directory. Note that the Mozilla <i>components</i> directory does not need to be on the <tt>PYTHONPATH</tt>,
|
|
but any modules used by your components must be set correctly. If anything
|
|
is wrong here you should get a normal <tt>ImportError</tt>.</li>
|
|
</ul>
|
|
<blockquote>
|
|
<p>Note that on Windows, the PYTHONPATH is generally maintained in the
|
|
Registry; however, you can set this variable at a DOS prompt, and it will still be
|
|
added to the core PYTHONPATH.
|
|
</blockquote>
|
|
<h2><a name="BuildingTheExtensions">Building</a></h2>
|
|
<p>The initial release of the Python XPCOM package has a very simple, hard-coded
|
|
build process. The intention is to include this package in the Mozilla
|
|
source tree, and integrate the build with the Mozilla build. Until this
|
|
happens, perform the following steps:</p>
|
|
<ul>
|
|
<li>Ensure you can successfully build Mozilla itself from source-code.</li>
|
|
<li>Unpack this source code, and change to the <i>xpcom</i> directory under
|
|
the root <i>PyXPCOM</i> directory.</li>
|
|
<li>For Windows, edit <i>makefile.stupid.win</i>, while for Linux, edit <i>makefile.stupid.linux</i></li>
|
|
<li>As per the instructions at the top of the makefile, edit the MOZ_SRC,
|
|
INSTALLDIR and PYTHON_SRC definitions appropriately.</li>
|
|
</ul>
|
|
<h3>Build Example: Building on Windows</h3>
|
|
<p>For this example, we will assume that the source-code for Mozilla is in C:\src\mozilla,
|
|
the source-code for the PyXPCOM package is in <i>c:\src\pyxpcom</i>. Further, we assume
|
|
that you have Python 2.0 installed in <i>C:\Python20</i>, and wish to install
|
|
the built Python XPCOM package so it exists in <i>C:\Python20\xpcom</i>.</p>
|
|
<p>To build the package in this environment, you would perform the following
|
|
steps:</p>
|
|
<ul>
|
|
<li>Unpack the PyXPCOM package source-code into the appropriate directory</li>
|
|
<li>Edit makefile.stupid.win with the following changes:<br>
|
|
<i>MOZ_SRC=c:\src<br>
|
|
INSTALLDIR=C:\Python20<br>
|
|
PYTHON_SRC=C:\Python20</i></li>
|
|
<li> From the top-level Python xpcom source directory (i.e., the
|
|
directory with <i>makefile.stupid.win</i>), execute the command:<br>
|
|
<i>nmake -f makefile.stupid.win install</i></li>
|
|
</ul>
|
|
<p>NOTE: To build a Debug version of the Python XPCOM library, you can add <i>DEBUG=1</i>
|
|
to the nmake command-line.</p>
|
|
<p>If everything appears to work and you are brave, you may also like to execute
|
|
<i>make -f makefile.stupid.win test</i> to execute the test script.
|
|
Otherwise, continue to the following section where we confirm the installation
|
|
step-by-step.</p>
|
|
<h3>Build Example: Building on Linux</h3>
|
|
<p>For this example, we will assume that the source-code for Mozilla is in ~/src/mozilla,
|
|
the source-code for the PyXPCOM package is in ~/src/pyxpcom. Further, we assume
|
|
that you have ActivePython 2.0 installed in <i>/usr/local/ActivePython2.0</i>,
|
|
and wish to install the built Python XPCOM package so it exists in <i>/usr/local/ActivePython2.0/lib/python2.0/site-packages/xpcom</i>.</p>
|
|
<p>To build the package in this environment, you would perform the following
|
|
steps:</p>
|
|
<ul>
|
|
<li>Unpack the PyXPCOM package source-code into the appropriate directory</li>
|
|
<li>Edit makefile.stupid.linux with the following changes (substituting
|
|
username accordingly):<br>
|
|
<i>MOZ_SRC=/home/username/src<br>
|
|
INSTALLDIR=/usr/local/ActivePython-2.0/site-packages<br>
|
|
PYTHON_SRC=/usr/local/ActivePython-2.0</i></li>
|
|
<li>Build: As a regular user, from the top-level Python xpcom source
|
|
directory (i.e., the directory with <i>makefile.stupid.linux</i>), execute
|
|
the command:<br>
|
|
<i>make -f makefile.stupid.linux DEBUG=1</i></li>
|
|
<li>Install: Log in as a user with permissions to install into the relevant directories
|
|
(usually the root user). From the top-level Python xpcom source
|
|
directory (i.e., the directory with <i>makefile.stupid.linux</i>), execute
|
|
the command:<br>
|
|
<i>make -f makefile.stupid.linux DEBUG=1 install</i></li>
|
|
<li>Switch back to a regular user, ready for testing!</li>
|
|
</ul>
|
|
<p>NOTE: The instructions above are for a Debug build, as this is the default
|
|
Mozilla build type. If you have configured Mozilla to build a Release
|
|
version of Mozilla, you can drop the DEBUG=1 option. It is important that
|
|
PyXPCOM and Mozilla itself are consistent with respect to Release and Debug
|
|
builds. For more details, please consult the makefile.</p>
|
|
<p>If everything appears to work and you are brave, you may also like to execute
|
|
<i>make -f makefile.stupid.linux test</i> to execute the test script.
|
|
Otherwise, continue to the following section where we confirm the installation
|
|
step--by-step.</p>
|
|
<h2><a name="RunningTheTests">Testing your Setup</a></h2>
|
|
<p>The Python XPCOM Package has a complete test suite. If you are
|
|
impatient, you can simply execute <i>make -f makefile.stupid.linux test</i> (for
|
|
Linux) or <i>nmake -f makefile.stupid.linux test</i> (for Windows). If
|
|
this command indicates that the tests succeeded, then you can ignore the rest of
|
|
this section.</p>
|
|
<p>In the rest of this section, we walk through some simpler tests a step at a time,
|
|
to help diagnose any problems.</p>
|
|
<p><b>Note:</b> We recommend you do all your testing outside of <i> mozilla.exe</i>; it is far simpler to test all of
|
|
this using the PyXPCOM package stand-alone.</p>
|
|
<p><b>Note:</b> On Windows, if you use a debug build of Mozilla (i.e., in <i>dist\WIN32_D.OBJ\bin)</i>,
|
|
you <b>must</b> use <i>python_d.exe</i>; if you use a release build (i.e., in
|
|
a <i>dist\WIN32_O.OBJ\bin</i> directory), you must use <i>python.exe</i>.
|
|
<i>makefile.stupid.win</i> handles this automatically.</p>
|
|
<p>To test your setup:</p>
|
|
<ol>
|
|
<li>Start Python, and check<br>
|
|
>>> <i>import xpcom</i><br>
|
|
works. If not, <a href="#PYTHONPATH">check your PYTHONPATH</a> - the
|
|
main PyXPCOM package can not be located..</li>
|
|
<li>Check<i><br>
|
|
>>> import xpcom._xpcom</i><br>
|
|
|
|
works. If not, then most likely your <a href="#MozillaDirectory">Mozilla
|
|
directory is not on your path</a>, or something is wrong with <i>_xpcom(_d).pyd/_xpcommodule.so</i>.</li>
|
|
|
|
<li>Next run a simple test: <i>test/test_misc.py</i>. With a Windows debug build, the command may look like:<br>
|
|
<i>C:\Anywhere> python_d \src\python\xpcom\test\test_misc.py<br>
|
|
</i>or on Linux<br>
|
|
<i>/home/user/src/mozilla/dist/bin$ python /home/user/src/python/xpcom/test/test_misc.py</i></li>
|
|
</ol>
|
|
<p>If you can't get this going, you won't get much further! If you do, the
|
|
next step is to register our test component and run our full test suite.</p>
|
|
<h2><a name="Registration">Registering the Loader and Test Component</a></h2>
|
|
<p>First register the generic Python loader. For instructions, see the <a href="file:///F:/src/as/Komodo/src/pyxpcom/xpcom/doc/architecture.html">architecture
|
|
document</a>. Do this only once, regardless of how many
|
|
Python components you have. Then install the test component itself, and
|
|
finally you can test it!</p>
|
|
<h3>Registering the Python Loader and Component</h3>
|
|
<p>To register the Python Loader and Component:</p>
|
|
<ol>
|
|
<li>Ensure the build process has put <i>pyloader.dll </i>(or <i>modpyloader.so</i>
|
|
for Unix), and the files <i> py_test_component.py </i> and <i> py_test_component.idl</i> into
|
|
the Mozilla <i>bin/components</i> directory. If not, copy the files
|
|
there manually.</li>
|
|
<li>Run <i>regxpcom</i>. <i>regxpcom</i> is a standard Mozilla
|
|
executable, found in the <i>bin</i> directory, that detects whether the DLL and .py
|
|
files have been added and registers them accordingly. You should
|
|
see a few messages that include the following:</li>
|
|
</ol>
|
|
<blockquote>
|
|
<pre>Registering: PythonComponentLoader
|
|
Registered 1 Python components in pyloader.dll
|
|
nsNativeComponentLoader: autoregistering succeeded
|
|
Auto-registering all Python components in F:\src\mozilla\dist\WIN32_D.OBJ\bin\components
|
|
Registering: PythonTestComponent
|
|
Registered 1 Python components in py_test_component.py</pre>
|
|
</blockquote>
|
|
<p>If so (or you see no message at all), you are ready to run the test suite.</p>
|
|
<p><b>Note</b>: If you execute this same step a second time, you will not
|
|
see any of the above mentioned messages. XPCOM knows that nothing has
|
|
changed since you last ran <i>regxpcom</i>, so nothing is registered. If
|
|
you do not see these messages the first time you run it, there is the
|
|
possibility that some other process, possibly the build process, has already
|
|
executed this step.</p>
|
|
<h2><b>Running the Test Suite</b></h2>
|
|
<p>To run the test suite, run <i>xpcom/test/regrtest.py.</i> This runs the
|
|
tests and ensures that the test output is as expected. If all tests
|
|
pass, you have a fully functioning Python XPCOM package. Enjoy!</p>
