Re: [Zope-dev] Re: z3 server+publication refactor for z2
FYI there was a couple of hours work done on this today at the sprint in Paris. It seemed to us the the next necessary step in Sidneis branch was to make Zope2 traversal adapters for non-zope3 objects. This work has now started, in the form of refactoring the BaseRequest traversal into Zope3 type traversal chunks that we can make adapters of. Current problem: getRole is called with the entry_name unless the subobject was gotten via a getitem interface, when it's called with None. As we want to do the getRole part outside of the name traversal, we don't know in which way the name was gotten. So we need to solve that tomorrow somehow.

Well, the biggest is making an adapter for the Zope 3 request so that it implements the same interface as the Zope 2 request. Other than that, it was pretty much working. We might not need a special request type. We could try to continue to use ZPublisher's request implementation, at least for now. In WSGI, the application gets the env and streams. In Zope 3, this is the WSGIPublisherApplication (see zope.app.wsgi). It is responsible for creating the request, but it chooses to delegate to an HTTP request factory. This factory decides, based on certian rules, whether we're dealing with a plain HTTP/WebDAV request or XML-RPC or browser etc. In Zope 2, this factory (or the WSGIPublisherApplciation itself) could simply create a ZPublisher request object. After creating the request, the WSGIPublisherApplication would turn the request over to ZPublisher.Publish.publish and sends it on its normal path. This is the small solution in which we provide a WSGI-capable frontend to the ZPublisher. The big solution would be to replace ZPublisher with zope.publisher and a custom Zope2-oriented publication + appropriate traversers. In this case I wouldn't advise for adapting the Zope 3 request to a Zope 2 request. I would rather introduce a new request type, IZope2Request, based on zope.publisher's IBrowserRequest, that provides all the additional Zope 2 API. I think the big solution would take a considerable effort. It's less than three weeks before feature freeze. That is very little time even for the small solution. Oh, and now I recall, we don't have 'streaming', 'chunked', We have something along those lines. Jim can say more. and 'gzipping' yet, though the latter two would be easily implemented as wsgi middleware (could even use the implementation from django/turbogears). Yeah. Good idea. Perhaps we can see if we can create a common wsgzip package or something that is open to all WSGI-capable Python frameworks.

I think it'd be technically possible to have both solutions coexist. After all, that's what we're doing in Zope 3. zope.app.twisted and zope.app.server can coexist easily, I don't see why it shouldn't be possible in Zope 2. They must coexist in any case. We can not get rid or replace a major component - neither without breaking compatibility nor without deprecation. -aj -- ZOPYX Ltd. Co.
