Bug ID: 6689
Summary: hgWeb installed via PIP on IIS breaks when updating to
Python 3.x
Product: Mercurial
Version: 6.1.1
Hardware: PC
OS: Windows
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: hgweb
Assignee: bugzi...@mercurial-scm.org

Screencap of the error message received
Environment:
* Windows Server 2019 or 2022 with IIS Role installed.
** CGI and ISAPI restrictions role features are installed
* Python 2.7.18 installed to directory c:\Python27
* Python 3.10.4 installed to directory c:\Python310
* Mercurial package installed via "pip install mercurial" for the appropriate
Python version
* hgweb.cgi file taken from repository, only modifications are the "shebang"
line on top to point to the Python executables (which doesn't seem to do
anything in IIS) and the config path.
Background:
I have a Mercurial version 6.1.1 site running on Python 2.7 that is serving
repositories as expected. To upgrade the Python version, I expected to be able
to install Python 3.10 , navigate to c:\python310\scripts, run the command "pip
install mercurial", and update my web.config and hgweg.cgi files to point to
the new Python version's executable.
This procedure to upgrade the Python version (minus the web.config part) works
when using ApacheLounge to host the content. When I try it in IIS, I receive
this error message:
