I recently upgraded the systems to Python 2.6, and the worst part of that was getting
Trac to work again.
This guide assumes you have a working install of Trac on Python 2.5/mod_python/Apache2.2 already, as described in the
Trac install guide, and that
Python 2.6 is installed.
What needs to be done:
- Install Python 2.6 and Trac for 2.6
- Build a new version of mod_python
- Build a new version of libsvn
- Replace Apache DLLs
Visual C++ 2008 Express Edition or any retail version of VS 2008.
Install Python 2.6 and
Trac on 2.6 (using “
easy_install trac” is recommended)
You’ll probably also want to easy_install
Pygments for source highlighting.
Building mod_python for 2.6
guide to mod_python covers the creation and installation of a compatible version of the module.
At this point, you should be able to restart Apache and load up your “old” Trac on Python 2.6, but with the error message that “svn” support is not installed.
A pre-built version of this can be found here:
Building svn/libsvn for Python 2.6
Follow my previous
guide to compile and install Python SVN bindings.
At this point, if you restart Apache, your Trac will most likely throw an exception about “_mod” being undefined.
Replacing Apache DLLs to make libsvn work
There’s a slight difference between libapr-1.dll as supplied with Apache 2.2 and the one we built together with libsvn, so
the fix is to replace the one in your Apache2.2\bin folder with the one you built yourself, and copying all the libsvn*.dll files you built in the previous step to the same folder.
Restarting Apache now should make Trac work fully, with Subversion support.
