Prologue: I'm going to violate the cardinal rule of question asking and
not post code, simply because I'm not to the point of having a test
case yet. That said:
We have had running, for a few months now, this stack:
CherryPy -> modpython_gateway.py -> mod_python
As I investigated, I discovered (I didn't set it up) that
modpython_gateway.py is a full WSGI layer that wraps CherryPy. So,
between some PYTHON_PATH problems we've been having and in interest of
moving off of an unmaintained project, I set out to investigate
mod_wsgi (thanks Graham for the pointer...that was me on the mod_python
list).
So, I've got it somewhat working. Our custom CherryPy bootup script has
an application object (retrieved from cherrypy.tree.mount) that is
found, and anything exposed as regular HTTP works fine. I say regular
HTTP because we have custom logic to expose some methods that pertain
to AMF calls.
On the original stack, all worked fine. However, under mod_wsgi methods
exposed via our custom expose_as_amf() logic return a 404. And it's
not Apache, I get the 404 from CherryPy.
The only major thing that might have changed is that our source path is
no longer first in sys.path. mod_python allows you to do this:
PythonPath "['/home/wsbuild/wordstream/server/wordstream/src']+sys.path"
Whereas mod_wsgi only has a directive for appending to sys.path.
Other than that, is there any code I need to look for that would change
the behavior between the original stack and the pure mod_wsgi stack?
Here is our expose as http methods and expose as amf methods if it helps
any. (Mind the wrap)
@staticmethod
def expose_as_http(func=None, alias=None):
def http_deco(f):
expose_func = cherrypy.expose(func, alias)
f = expose_func(f)
cleanup_func =
cherrypy.tools.post_request_connection_cleanup_tool()
f = cleanup_func(f)
return f
return http_deco
@staticmethod
def expose_as_amf(uri, name=None, authenticator=None):
'''Decorator to expose a function as an AMF service
@param uri: AMF service endpoint URL
@type uri: str
@param name: AMF service name (if None, uses function name)
@type name: str
@param authenticator: Custom Authenticator (if None, uses
self.authenticate)
@type authenticator: function
'''
parent_vars = sys._getframe(1).f_locals
def null_deco(f):
if name:
method_name = name
else:
method_name = f.__name__
parent_vars.setdefault('amf_methods', []).append((uri,
method_name, f, authenticator))
return f
return null_deco
Thanks for any pointers!
