You also have to integrate it into the build and carefully arrange the dependencies. You also have to find a free and sensible base address for the dll. At last the new modules must be integrated into the MSI installer script.

So, I would have to change those scripts (if I don't change the libraries), or change the libraries.

It's not an ugly hack, it's a well known feature. Add you don't have to change a lot of places, too. It's sufficient to add the alias at the entry point of your application (the script that starts your app). Once the alias sys.modules]'mmap'] = ralfmmap is set, every import mmap gets your ralfmmap.

On Windows lots of modules are linked into the python main dll. The file PC/config.c contains a list of all modules. From the point of the maintainer it's much easier to link the modules into the main dll instead of creating standalone dlls. I also suspect that it's much faster because relocation is slow (see PC/dllbase_nt.txt). Martin or Mark can give you a better answer. Why do you want to overwrite the existing module instead of using a different name like ralfmmap? import ralfmmap as mmap sys.modules]'mmap'] = mmap Christian ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
[Python-Dev] why is mmap a builtin module on windows?
Hi all, I want to use the mmap module from python trunk with python 2.5. On Linux I can easily replace it, as it is a dynamically loaded module. On windows it is a builtin module and I fear that I must compile python on windows (or resort to some other ugly hack) What is the reason for mmap being a builtin module?
