Mercurial 1.7.2+ higher source packages cause IIS7 / isapi-wsgi (hgwebdir_wsgi) to fail

[Ethan Brown]

The solution is to download the source from
http://mercurial.selenic.com/release and extract it to a directory where a
'pure' Python version can be installed from.  Steps described here:
http://mercurial.selenic.com/wiki/WindowsInstall


python setup.py --pure build_py -c -d . build_ext -i build_mo --force
python setup.py --pure install --force

It would appear that something changed from 1.7.1 to 1.7.2 and later that
causes installation via mercurial-1.7.2.win32-py2.6.exe to longer function
properly when using Isapi-Wsgi under IIS.

Unfortunately, I don't know enough about Python (or have the time at the
moment) to figure out the root cause.
