Why do you want to be able to change the working directory? Generally it is not a good idea to be writing a WSGI application which depends on being executed within a specific current working directory. This is because there is no guarantee across different web hosting environments that one can control the application working directory and if you try to change it yourself from the application code then you may run into issues with multithreading and different parts of an application wanting it to be set to different values at the same time. Thus, as explained in the Apache mod_wsgi documentation, specifically section "Application Working Directory" of: http://code.google.com/p/modwsgi/wiki/ApplicationIssues you should aim to always use absolute paths to access the file system. To make an application somewhat moveable, you can calculate the absolute path based relative to the __file__ attribute of a Python module. That said, if running in daemon mode of Apache mod_wsgi, you can control the home directory of the application using the 'home' option to WSGIDaemonProcess. In Apache mod_wsgi 2.0, daemon processes will actually by default change to the home directory of the user the process is running as if that directory isn't overridden through that option. For details of these options see WSGIDaemonProcess directive documentation in: http://code.google.com/p/modwsgi/wiki/ConfigurationDirectives In embedded mode of Apache mod_wsgi there is no way to specify through the configuration what the application working directory should be, as the processes are shared by other Apache modules and because it is a shared environment, it would be bad practice to be trying to change the working directory as something else could easily change it and your application would fail if it was dependent on the working directory remaining the same. BTW, for Apache mod_wsgi questions are better directed to the official mod_wsgi list at: http://groups.google.com/group/modwsgi The reference to the list and all the documentation can be found at: http://www.modwsgi.org Graham _______________________________________________ Web-SIG mailing list Web-SIG@python.org Web SIG: http://www.python.org/sigs/web-sig Unsubscribe: http://mail.python.org/mailman/options/web-sig/archive%40mail-archive.com
