Setting up Mercurial on IIS

I have just set up a Mercurial server using IIS to serve the requests. I found that the following blog post was a great step by step guide to setting it up http://blog.schuager.com/2010/03/how-to-setup-mercurial-server-on.html.

The reason for this is that I had installed the standalone version of Mercurial and that it could not reference the compiled C versions of the python modules. I fixed this by copying the pure python modules into the lib directory.

I disabled this for the whole repo by adding the following to the web.config at the top level of the IIS hg app.

  "Generates a UUID"
  (shell-command "python -c \"import uuid;print uuid.uuid4()\"" t)
