Why use apply(foo.__call__, ..)?
by Ross Boylan 01 Sep '00

01 Sep '00

In looking over the code for ZWiki/ZC, I see a lot of places with the following construct: apply(foo.__call__, some, arguments) Why not just say foo(some, arguments)? Examples of the construct from ZWikiPage.py: apply(self.aq_parent.standard_wiki_page.__call__, (None, REQUEST, REQUEST.RESPONSE)) or apply(DTMLDocument.__call__,(self, self.aq_parent, REQUEST, REQUEST.RESPONSE)) [OK, in this case the question technically is why use apply(foo.__call__, (a, b, c)) instead of foo(a,b,c)? Hmmm... x.foo(a, b, c) -> foo.__call__(x, a, b, c).] These requests are mostly, if not entirely, directed at WikiPages/Headers/etc, whose definition is, in part, class ZWikiPage(DTMLDocument): #, CatalogAware): def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw): """Render a zwiki page, with standard header & footer """ I thought the use of keyword argument dictionaries in apply might explain this, but, as the two opening examples show, not all cases have keywords. Second, even if they do one could say aDocument(self, REQUEST, REQUEST.RESPONSE, kw). I understand from Johan that this is "inherited" code (in the non OO sense), so I thought I'd throw this out as a general question. Is there some subtlety of the interaction of Zope (acquisition, perhaps, or extension classes in general) and python that makes foo(x) and foo.__call__(x) have different meanings? Is it something about standard_zwiki_page, which I notice is not a regular python variable? I don't need the answer to this to do something; I'm just trying to understand how things work. Thanks.

2.2.1, Membership, and a __hash__ error.

I havent been able to reproduce Andy's issue yet either (though we're working to figure it out). At this point the only common thread seems to be "nested ZClasses", though it is apparently not as simple as that. Anyone seeing this problem who can provide me with a zipped up Data.fs and a _complete_ description of what (Python) products are installed in the affected installation would help greatly in being able to reproduce the problem...

New version of BTreeFolder
by Shane Hathaway 31 Aug '00

31 Aug '00

Hi gang, This version just fixes a bug with the folder contents tab on Windows. For some reason, on Windows 95 (and perhaps other platforms) the Python interpreter behaves differently enough that if you use a class attribute from a different module and put it in your own class, you may in fact be modifying its global context. It's probably a bug in Python. As a workaround, this version of BTreeFolders doesn't have the "details" tab anymore. http://www.zope.org/Members/hathawsh/BTreeFolder/BTreeFolder-0.1.1.tar.gz BTW has anyone done any semi-formal speed tests? It's rumored that a custom getattr in Python can cause a bit of a slowdown. We could write a custom getattr in C to solve the problem. But we don't want to do any premature optimization. Shane

New version of PortalMembership likely coming within 24 hours

If you said you had patches for me, now is the time. I have some fairly significant improvements and fixes ready (missing a deluser function at the moment, can't even find delItem in my tree anywhere...) (I've been working at it for the last 5 hours straight, my brain is a bit too fizzeled to remember who had patches for me) Bill -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.
