> Robin what kind of testing have you done on this change? Could you please try to do a fresh conversion of one the smaller repositories, like jtreg, to ensure that we haven't broken anything? The unit tests exercise the Mercurial extension quite a bit, but I really want to ensure we don't mess anything up with regards to the hg -> git conversion.

�� The jtreg repository is actually partially converted in the hgbridge tests, but yes, it makes sense to do something a little more extensive.. I'll kick off a few bigger conversions.
