[Zope-dev] support for low level HTTP Response logging?
Yo, searching the zope site and googling yielded too many data and no info, so I might as well ask it here. We are very interested in finding out the exact HTTP Responses that the zope server pushes towards the client. So is there a low level hook for logging the http responses ? We want the exact response, complete with all header info etc. Why not just sniff, you might ask? Well, we are developing a web application for mobile microbrowsers, and most these clients have no hooks for attaching a sniffer client side. Installing a sniffer server side is not possible for other reasons.

Re: [Zope-dev] LOTS of roles?

How about creating a role for each user (i.e. user user_id get's just the role user_id, instead of creating a role for for each possible (task,location) tuple. When creating a new user, the admin would have to just assign the permissions, instead of roles. This task could be made easier by creating template permission sets. Interesting idea... tell me if I'm wrong, but I see two obvious problems with this approach: 1) for one-role-per-user: we'd have to visit the security management for N objects in Zope and adjust the permissions every time we add a user. Whereas in my proposal, we only need to do that every time we add a site or change the tasks, which happens much less frequently. 2) for one-role-per-user, changing a user's privileges means wanding around the ZMI setting permissions on N objects. Whereas in my scheme, we can do that in one place (LDAP) by adding or removing a role or two. You might wind up with less roles and I bet administration is a lot easier. my guess is that in our case, the number of roles would be comparable. 200 sites * 10 tasks = 2000 roles 200 sites * 10 users = 2000 roles I think I still don't get all the characteristics of you application. So I'll try to post what I had in mind: - implement a kind of permission matrix: tasksxsites,i.e. permission 1X says that the user who has this permission is allowed to call taskX(site=1,...). Then in taskX you could check if the user has the permission 1X, and otherwise throw an exception. - write an UI which hides the existance of roles, instead let the admin assign permissions directly to users (by implictly creating one role named user_id with all the permissions the admin choose). Optionally give the admin some knobs to use permission templates or other helpers. Note that this could still be combined with normal roles for everything which has nothing to do with your sites. So I don't see why your point 1) and 2) could be an issue, unless you also need stuff like local roles for other things etc. - but that seems to be solvable through an UI too. Then you'd have sites*tasks permissions, and as many roles as you have users. And maybe you steered around the complexity problem w.r.t roles too. cheers, oliver ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Of course this most probably will bring performance down (or even the complete Zope, if there is a simple typo in the hacked code ;-) I assume You only need this for testing.

Are you mainly concerned about the http headers in the response, or the response body? If it is just the headers, Squid's log_mime_hdrs feature will log all HTTP headers from both the request and response for you for each request. If nothing else, perhaps it's a start...

After some more poking around, I've simplified the problem. I have a
product I created with a __call__ method:
def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw):
Call the selected template in the context of myself.
print REQUEST =
print str(REQUEST)
When this is called from DTML like this: dtml-var object REQUEST is {}
when this is called directly REQUEST is the real request information,
when it is called from python object(context, REQUEST) this works as
well.
This is as it should be.
You need to define the attribute isDocTemp=1 to tell
DTML to call an object with parameters None,_, i.e. like
a DTML object.

I've made that suggestion numerous times on the ZPT mailing list, with zero response. Just how much did you have to change to divorce ZPT from Zope? I've fully documented it (as required by the ZPT license). In a nutshell: - implemented MultiMapping as simple python modules - changed the way macros are handled to remove the computed attribute stuff (since it's an acquisition trick) - removed all references to acquisition (for cleanliness, no other reason) including some ZTUtils that won't work without it (ie. tree stuff) - altered the import statements so that I wouldn't clash with another version of ZPT if it were installed (or if Roundup was installed as a Zope Product) - significantly improved error reporting :) The critical change is the way that the macros are handled. The ComputedAttribute stuff just doesn't make sense (and is horribly complicated) when you're not using acquisition. The good news is that TAL requires no changes if you implement a dummy zLOG. I ended up removing the dependency.
