Serving HG repositories on Windows 2012 R2 Server.

Wed Sep 23 16:46:58 UTC 2015

We have Mercurial running, without changes to Python or Mercurial code, on Windows 2008 R2. The steps are documented on the https://mercurial.selenic.com/wiki/HgWebInIisOnWindows wiki page.

I believe the problem is that you have hgweb.cgi in the URL, which won't work. See section 3, Configuring IIS Rewrite Rules.

Subject: Serving HG repositories on Windows 2012 R2 Server.

Hi,

I'm trying to set up a 2012 R2 windows server with mercurial HG.
browsing, pull, clone,add,commit works. push doesn't work.

Setup:

Basic authentication, pass-through, SSL
Python 2.7 (had to modify random.py. line 114 to make it work)
I only have that single python version.

Using hgweb.cgi

mercurial-3.3.3.win32-py2.7.msi is installed in the python site-packages directory.

Browsing my repositories, cloning and updating on HTTPS works
However, I can't push.

Repositories are in c:\users\public\hg_repos
I have full rights in hg_repos and everything below.
Scripts are in c:\users\public\hgweb

I have placed a web.allow_push = * in .rc\hgrc in the repository

I have tried
mercurial-3.3.3.win-amd64-py2.7.msi
mercurial-3.5.1.win32-py2.7.msi
mercurial-3.5.1.win-amd64-py2.7.msi
mercurial-3.5.win-amd64-py2.7.msi
But none of these can even browse directories. (DLL load error. Dont know the name of the DLL)

In parallel with all this I have a regular (non-python) hg installation for "hg init" on the server.

Q1) Is there some setting in the IIS webserver itself that can prevent writing and cause the error?
Q2) Is there a known good installer configuration for Windows server 2012.
Q2a) is python 3.0 better? Is there a mercurial-python3.0 installer available?
Q3) Are there (simple) tools that can tell more aobut the error

Error:
password:
searching for changes
abort: HTTP Error 502: Bad Gateway

Or, with more detailed output:

abort: 'https://slasvn02/hgweb.cgi/TestRepo' does not appear to be an hg repository:
