1 # An example WSGI script for IIS/isapi-wsgi to export multiple hgweb repos
2 # Copyright 2010 Sune Foldager <cryo@cyanite.org>
3 #
4 # This software may be used and distributed according to the terms of the
5 # GNU General Public License version 2 or any later version.
6 #
7 # Requirements:
8 # - Python 2.6
9 # - PyWin32 build 214 or newer
10 # - Mercurial installed from source (python setup.py install)
11 # - IIS 7
12 #
13 # Earlier versions will in general work as well, but the PyWin32 version is
14 # necessary for win32traceutil to work correctly.
15 #
16 #
17 # Installation and use:
18 #
19 # - Download the isapi-wsgi source and run python setup.py install:
20 # http://code.google.com/p/isapi-wsgi/
21 #
22 # - Run this script (i.e. python hgwebdir_wsgi.py) to get a shim dll. The
23 # shim is identical for all scripts, so you can just copy and rename one
24 # from an earlier run, if you wish.
25 #
26 # - Setup an IIS application where your hgwebdir is to be served from.
27 # On 64-bit systems, make sure it's assigned a 32-bit app pool.
28 #
29 # - In the application, setup a wildcard script handler mapping of type
30 # IpsapiModule with the shim dll as its executable. This file MUST reside
31 # in the same directory as the shim. Remove all other handlers, if you wish.
32 #
33 # - Make sure the ISAPI and CGI restrictions (configured globally on the
34 # web server) includes the shim dll, to allow it to run.
35 #
36 # - Adjust the configuration variables below to match your needs.
37 #

44 path_prefix = 1 # This many path elements are prefixes (depends on the
45 # virtual path of the IIS application).

47 import sys
48
49 # Adjust python path if this is not a system-wide install
50 #sys.path.insert(0, r'c:\path\to\python\lib')
