[Zope-dev] zope.proxy explanation?
I'm trying to port zope.proxy to Python 3, and most tests seem to work, but investigating those two who doesn't is confusing. The first one is the test to prevent pickling. This works under Python 2, but as I understand it it should work by implementing a __reduce__ function that throws an exception. But that method is never called under Python 2. Instead a pickling error is thrown, but this is because the pickler has no special knowledge about proxies, and then tries to find __reduce__ and fails. Apparently the __reduce__of the proxy isn't found, weirdly enough. In Python 3, the base object now *has* __reduce__, so it *is* found and used, so the test fails. So there is something I'm missing here. It seems to be that two bugs cancel each other out under Python 2, and under Python 3 they don't, and the test fails. //Lennart ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] zope.proxy, c-extensions fallback?
Hi, I'am just playing with repoze.bfg in google appengine (gae) and stumbled over zope.proxy. I tried to use zodict.node.Node which depends on zope.location. zope.location depends on zope.proxy. Latter has mandatory C-extensions. Are there any plans to get rid of them as a fallback for those spezial cases like gae? For zope.interface it was possible too ... tia -- Jens W.

[Zope-dev] zope.proxy
Hi, Is there any documentation on zope.proxy other than the test? I don't speak C anymore. :) Basically, I'm curious if it would be possible to implement translation proxies that would allow getting and setting translated values for certain fields.

I have done something like this a while ago and always wanted to release it. *digs into svn* Ah. We didn't use zope.proxy at all. We differentiate between a real object and the object that carries the schema's translated fields. Have a look at the attached file, it contains the code that I extracted from a project in a hurry, but if the approach sounds reasonable to you, I'd be happy to put that into SVN.

Hi Christian, Thanks for this! Have a look at the attached file, it contains the code that I extracted from a project in a hurry, but if the approach sounds reasonable to you, I'd be happy to put that into SVN. Can you tell me a bit more about how this is hooked into publication? Where do you create the Translation object? How do you look up translations later and present the correct translation to users?
