Configuring the Notify extension

[Simon King]

I don’t know what is causing the “Access denied” error in the first configuration. Do you still get that error if you disable the notify extension altogether? How about if you set “test = True” in the [notify] section?

The [notify] “config” setting in mercurial.ini would need to be a local filename (on the server) - it can’t be a URL. So it might be something like “C:\repos\AnotherRepo\subscribers.txt”, where “C:\repos” would be replaced with whatever path contains AnotherRepo. However, I would guess that if you get this working, you’ll just be back to the “Access denied” error again.

Running mercurial behind IIS makes debugging a bit more difficult. I would suggest that you start by running “hg serve” from a command prompt on the server, and pushing to that process. If you still get "Access denied”, and there’s no useful output on the server command-line, try adding “--verbose --traceback” to the “hg serve” command.

If it works when pushing to “hg serve”, but not when mercurial is running under IIS, I would guess that the user account running IIS doesn’t have appropriate permissions on the repository.

Let us know how you get on,

Simon

At first, the server really did send emails (but only to the first email in the list, if there was a comma-separated list, as in the description). After a time, however, something changed and now, I am unable to produce a single email notification, no matter how I try.
