Indeed I am using mod_wsgi. However, I cannot see how to set PythonInterpreter to 'main_interpreter'. So far as I can judge, this should be done through a declaration such as this in httpd.conf: <Location /SDPublisher> SetHandler mod_wsgi PythonInterpreter main_interpreter </Location> (according to what I could find at http://trac.edgewall.org/wiki/TracModPython) but this does not work, or rather Apache will not start with this included. help..! ________________________________________ From: Graham Dumpleton [graham.dumpleton at gmail.com] Sent: Wednesday, December 16, 2009 12:34 AM To: Peter Robinson Cc: mod_python at modpython.org Subject: Re: [mod_python] Using mod_python Berkeley DB XML, XmlManager, with MacOSX Tiger/Leopard/SnowLeopard (again) Are you definitely using PythonInterpreter set to 'main_interpreter'? Are you stuck with using mod_python? Any way you can use mod_wsgi? Since been discovered that even in main interpreter, mod_python's usage of GIL thread state APIs is wrong. The mod_wsgi module gets it right, although still have to tell mod_wsgi to use main interpreter as well to avoid other issues.
