[Zope-dev] Re: SOAP Support for ZOPE

Hi Brian:

I discussed with Michel Pelletier and he will help to produce a patch
that exactly implements your proposal that we'll send to you for your
review. Then we'll just provide an outside Product that calls the
registration function.

Thanks a lot for your suggestions...

Hi all - having had to implement a monkey patch product before to enable
SOAP, I'd like to make a few observations and a suggestion:

  - It is a pain to do anything with SOAP because the
    publisher has a hard-coded idea that anything xml must
    be xml-rpc

  - There is currently no easy way around this w/o monkey
    patching, which then leaves you vulnerable to future
    changes to the publisher

  - Opinions on the state of SOAP support in the Python world
    are far from unanimous - I think it would be premature to
    put a particular implementation into Zope proper

  - That said, Zope should make it possible for Cignex and
    others to provide SOAP support as add-on products without
    unreasonable contortions

So the suggestion: I think we'd be in a better place if we:

  - Fix the publisher to at least recognize a SOAP request vs.
    an xml-rpc request

  - Provide some kind of 'registration hook' so that a Product
    can register with the publisher to handle SOAP requests

  - Have the publisher hand off where appropriate to a registered
    SOAP handler if installed, else return an HTTP NotImplemented
    or similar if there is no SOAP handler

  - Apply the KISS rule: only one product can register to the be
    the SOAP handler, and resist turning this into any kind of
    grand-unified-pluggable-publisher architecture ;)

This would be minimally disruptive to the Zope core, while enabling
people interested in SOAP to evolve different solutions without
everybody having to buy into a particular approach or implementation
right now.
