Hi: I think that the possibility of having "inactive" objects, objects that are instantied, exist in the ZODB and in the folder tree but are invisibile to the Zope machinery (acquisition, rendering, itemizing) by setting/unsettting a property flag would also be something of extreme usefulness.

ZPT: how to access property sheet of custom ZClass
by David Hart 07 Mar '02

07 Mar '02

Hi! I'm implementing a simple db, using the same methods in the JobBoard example. I looked at Kube, but I'd like something a bit more generic. I'm trying to make add/edit forms and display pages as simple as possible. Rather than have custom versions of all of these, each with copies of the same property names, I'd like to pull the property/attribute names from the property sheet of the ZClass in the Product I added. Something like: <span tal:repeat="props python:root.Control_Panel.Products.CEdb.cedb_record.propertysheets.common.record_default_properties.attrs()"> <p tal:content="props"></p> </span> The above example is probably very wrong for many reasons-- it shows my lack of experience with TAL, python and Zope innards in general -- but I think it conveys what I'm trying to do. I'm not sure if I can use "python:object.attrs()", or even if the objects under Control Panel are accessible to ZPT as the above example produces a guarded_getattr error. Also, is there a more generic or elegant way to refer to the record_default_properties object? Any help would be much appreciated! Regards, Dave

Is this a suggestion that TF go into the core? One other (major) problem with TF is that it breaks session tracking site-wide, or at least the ability to have more than one session id manager per Zope instance in CST; I'm not sure about sessions in Zope 2.5... TF seems to have too much normalcy-hijacking magic to go into the core, if you ask me...

recursion depth exceeded
by Terry Kerr 06 Mar '02

Hi, I am running a fairly high traffic Zope server where people occassionly ftp files in and out of the server. Approximately once per week, the zope process will go to using 99%CPU and stay like that untill it is restarted. The error shown in the stupid log file is: 2002-03-06T01:22:41 ERROR(200) ZServer uncaptured python exception, closing channel <zope_ftp_channel connected 202.129.84.50:64011 at 8ac4ecc> (exceptions.RuntimeError:maximum recursion depth exceeded [/usr/local/lib/python2.1/asyncore.py|poll|104] [/usr/local/lib/python2.1/asyncore.py|handle_write_event|393] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|handle_write|147] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|initiate_send|209] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/asynchat.py|refill_buffer|190] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/ftp_server.py|close|179] [/usr/local/zope/Zope-2.4.3-src/ZServer/medusa/ftp_server.py|close|903] [/usr/local/lib/python2.1/asyncore.py|close|355] [/usr/local/lib/python2.1/asyncore.py|del_channel|241] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] [/usr/local/lib/python2.1/asyncore.py|__getattr__|361] .... and so on...

I have looked into it, but most of it is over my head and I was hoping somebody could help. I have tried to reproduce the error, but without success.

WebDAV quibble -- fix in 2.6?
by Casey Duncan 06 Mar '02

06 Mar '02

This maybe more 2.6 (or even 2.5.1 final) fodder: I notice that in a vanilla Zope install, Anonymous users are allowed access through WebDAV. This is bad for two reasons: 1. From a security perspective this discloses way too much information about your site to the outside world. 2. Due to vagarities of WebDAV authentication, it makes it impossible to edit anything, because I guess the WebDAV implementation is too stupid to force a login when you try to lock something as anonymous (instead is returns a 500 server error). To get around this you have to create or copy an object to force a login. This problem disappears if everyone must login to access WebDAV at all. So the question is: Is there a good reason why WebDAV access is granted to anonymous by default? If not I vote we change it. /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association c.duncan(a)nlada.org \---------------------------------------------------/

two hard questions
by Tim McLaughlin 06 Mar '02

06 Mar '02

Firstly, I'm trying to return a lazy list to a dtml-in, but it seems that the __getitems__ are all called up front.... This is the class and the print statement shows up in debugging before any debugging output from within the dtml-in: class LazyList: def __init__(self, root, selections): self._root = root self._selections = selections def __getitem__(self, index): s = self._selections[index] print s.getPath() ##### this is executed for all items before anythingwithin the dtml-in o = self._root.restrictedTraverse(s.getPath()) o.setSelection(s) return o def __len__(self): return len(self._selections) Does this mean that dmtl-in touches all of the objects first for some reason? Or am I missing something? Second hard ?..... Is there any way to wrap a Folder subclassed instance within another class so that I can override some methods on an instance by instance basis? I tried doing a .__class__ replacement, but for whatever reason, Zope machinery seems to keep it from taking effect. Any ideas? I've tried about 5 different approaches to no avail :( Sincerely, Tim McLaughlin -- Tim McLaughlin Iteration ZERO, Inc. - www.iterationzero.com 703.481.3983

Right, but works only if the string-representation is not greater than the max-value of an integer. The following does not work for me. <dtml-let longnumber="2400000000L"> update tbl_test set adresse = <dtml-sqlvar longnumber type="int"> </dtml-let> Greetings -- Andre Schubert EMail: Andre.Schubert(a)km3.de Tel: 03774 6625-78 km3 teledienst GmbH Fax: 03774 6625-79
