[Zope3-dev] zope.app.wsgi + zope.app.server.main

[Phillip J. Eby]

Just a question here...  it seems to me that the approach recommended in 
the zope.app.wsgi README for starting a server may be incorrect.  It 
recommends using zope.app.server.main.setup(), but this creates a 
ThreadedTaskDispatcher,  as well as possibly creating servers.

This seems wrong for a WSGI application, which is not a web 
server.  Indeed, looking some more at zope.app.server.main, it seems that 
the 'debug()' function is actually what's needed.  IOW, it seems that 
instead of:

     db = setup(load_options(args))

the correct thing to do would be:

     db = debug(args)

If I may suggest a change, perhaps the 'debug' function might be renamed 
(or aliased) as 'serverless_startup' or something similar, since telling 
people to use 'debug' might be a bit weird.

By the way, there is currently an active discussion on the Web-SIG 
regarding deployment configuration for WSGI applications; I hope that we 
will soon have a concrete recommendation for how to have a server tell a 
WSGI application where to get its configuration file(s) from.  This would 
allow us to add a bit more code to zope.app.wsgi, and then be able to 
deploy Zope applications in deployment-ready WSGI servers without requiring 
the user to write a startup script at all.
