|
|
|
#
|
|
|
# Requirements:
|
|
|
# - Python 2.6
|
|
|
# - PyWin32 build 214 or newer
|
|
|
# - Mercurial installed from source (python setup.py install)
|
|
|
# - IIS 7
|
|
|
#
|
|
|
# Earlier versions will in general work as well, but the PyWin32 version is
|
|
|
# necessary for win32traceutil to work correctly.
|
|
|
#
|
|
|
#
|
|
|
# Installation and use:
|
|
|
#
|
|
|
# - Download the isapi-wsgi source and run python setup.py install:
|
|
|
# http://code.google.com/p/isapi-wsgi/
|
|
|
#
|
|
|
# - Run this script (i.e. python hgwebdir_wsgi.py) to get a shim dll. The
|
|
|
# shim is identical for all scripts, so you can just copy and rename one
|
|
|
# from an earlier run, if you wish.
|
|
|
#
|
|
|
# - Setup an IIS application where your hgwebdir is to be served from.
|
|
|
# On 64-bit systems, make sure it's assigned a 32-bit app pool.
|
|
|
#
|
|
|
# - In the application, setup a wildcard script handler mapping of type
|
|
|
# IsapiModule with the shim dll as its executable. This file MUST reside
|
|
|
# in the same directory as the shim. Remove all other handlers, if you wish.
|
|
|
#
|
|
|
# - Make sure the ISAPI and CGI restrictions (configured globally on the
|
|
|
# web server) includes the shim dll, to allow it to run.
|
|
|
#
|
|
|
# - Adjust the configuration variables below to match your needs.
