Re: [Zope-CMF] How to get Type in manage_afterAdd?
by Florent Guillaume 01 Feb '02

01 Feb '02

[sent to zope-dev] This problem is due to a deep bug in the current implementation of the Types Tool: a created object has no way to know its portal_type during construction (the constructor doesn't have this information, thus nor __init__ nor the hooks like manage_afterAdd can have it). I thought that this bug was already in the Tracker but I don't find it. Anyone knows ? Anyway I'd propose the following: we need, in constructInstance, to somehow pass the portal_type to the object constructor. Unfortunately this has to be backwards-compatible with all the constructors out there that don't know about it. I see two possible ugly solutions to do it: - do "constructor.__portal_type = portal_type" before calling constructor(...), and the constructor does something like: def manage_addFoo(...): try: portal_type = manage_addFoo.__portal_type manage_addFoo.__portal_type = None except: portal_type = None ... - in constructInstance, use introspection (getargspec) to look if the constructor accepts a portal_type=xxx named parameter, and pass it if it does. Anyone sees something cleaner ? :-) Florent Jon Edwards <jon(a)pcgs.freeserve.co.uk> wrote: > I've created a new product - "organisation", which has a property > "org_type", which I set in manage_afterAdd by doing - > > self.org_type = self.portal_type > > - which then gets catalogued.

Zope 2.5. cAccessControl.c tentative patch
by Matthew T. Kromer 01 Feb '02

01 Feb '02

FYI, those people who had to set ZOPE_SECURITY_POLICY to PYTHON are advised to apply the following Patch for 2.5's cAccessControl.c module and see if it helps. As far as I can see, it solves the Zope 2.5 problems reported by Martijn Faassen with ParsedXML. -- Matt Kromer Zope Corporation http://www.zope.com/ Index: cAccessControl.c =================================================================== RCS file: /cvs-repository/Zope/lib/python/AccessControl/cAccessControl.c,v retrieving revision 1.13 diff -u -r1.13 cAccessControl.c --- cAccessControl.c 11 Jan 2002 17:14:27 -0000 1.13 +++ cAccessControl.c 1 Feb 2002 17:27:31 -0000 @@ -1703,6 +1703,7 @@ Py_DECREF(r); r = self->__roles__; if (r == NULL) goto err; + Py_INCREF(r); } /*|

Generating abstracts in ZCatalog
by Cuthbertson, Mark 01 Feb '02

01 Feb '02

Hi, I'm quite new to all this Zope development but seem to be picking things up quite nicely. However, I am having a problem generating abstracts for my Search Engine. It's something that I used to be able to do quite easily in IIS / ASP but being new to Zope I can't seem to find a way how to do it automatically. Firstly, is this possible within Zope? And if so, how? Thanks in advance, and apologies if there is an obvious answer to this that I've missed (even though I did painstakingly search through the archives!)

Re: [Zope-dev] Call Profiler

We found once we'd turned this onto our production code (and Richard had made my initial vile hack actually work in a way that didn't cause bleeding from the brain) we were able to very very quickly spot a whole lot of stuff that was Just Not Doing The Right Thing. Unfortunately, the existing python profiling stuff is at too low a level to be useful - this stuff really fills a need. Plus, if it's integrated into Zope, Richard doesn't have to spend work time on maintaining it :) Anthony
