February 2002 - Zope-Dev

Increased community participation in collectors
by Ken Manheimer 22 Feb '02

22 Feb '02

We've changed the Zope issue collectors so that any authenticated (logged-in) visitors can comment on issues, not just collector staff and the requester. This is all in the pursuit of quality information flow - some of you have asked for the ability to include your illuminating experiences and/or solutions to existing issues, now you can. Please be discrete with this - "me too"s can drown out crucial info. Currently, all the collector.zope.org collectors have authenticated-visitor commenting enabled: http://collector.zope.org/Zope http://collector.zope.org/Zope3-dev http://collector.zope.org/ZopeOrg http://collector.zope.org/ColDev Commenting in an issue does not "subscribe" you to the issue - that may be spiffy idea, but it'll have to wait for another day. -- Ken klm(a)zope.com

Memory Problem with 2.3.3
by Andre Schubert 21 Feb '02

21 Feb '02

Hi, I have a problem with my Zope 2.3.3 running on a redhat immunix 6.2. The problem is that the zope-threads are growing up. I have running a top since yesterday. 2 days ago the size of all zope-processes was 44MB, yesterday it was 54MB today it is 64MB. This means to me, that all threads are growing up 10MB a day. If have also looked in the debug-information at the top-refcounts. OFS.Image.Image has a delta of around +1500... Is there a problem with OFS.Image.Image, are these objects never closed ???? Please Help Regards, -- Andre Schubert EMail: Andre.Schubert(a)km3.de Tel: 03774 6625-78 km3 teledienst GmbH Fax: 03774 6625-79

ZClasses and Python
by Andre Schubert 20 Feb '02

20 Feb '02

Hi all, i have a little question on ZCLasses and Python. Lets Say i have python-base-class foo which is folderish. I have a zclass bar which has the class foo as base class. Now i have defined as new propertysheet instance in bar called foobar. If i change the properties of foobar, then manage_editProperties is called( i'am right ). Is there a way to catch the manage_editProperties function(called from foobar) in my base-class foo ???? Thanks as P.S.: I hope there is someone understanding this :) -- Andre Schubert EMail: Andre.Schubert(a)km3.de Tel: 03774 6625-78 km3 teledienst GmbH Fax: 03774 6625-79

[ANNOUNCE] ArielPartners releases CVSFile 0.7
by Craeg K. Strong 18 Feb '02

18 Feb '02

This is the first public release of our CVSFile <http://www.zope.org/Members/arielpartners/CVSFile> product. CVSFile enables Zope content to be served out of files residing in CVS sandboxes, and provides access to common CVS functions through the web in the Zope Management Interface. Why not simply use ZCVSFolder <http://www.zope.org/Members/sspickle/ZCVSMixin>? Because CVSFile stores files in CVS as normal files, rather than as Python "pickles." This makes it easy to use the same content, held in CVS, in both Zope and non-Zope contexts. CVSFile extends ExternalFile <http://www.zope.org/Members/arielpartners/ExternalFile>, and therefore inherits all of its functionality.

[ANNOUNCE] ArielPartners releases ExternalFile 0.9
by Craeg K. Strong 18 Feb '02

18 Feb '02

This is the third public release of our ExternalFile <http://www.zope.org/Members/arielpartners/ExternalFile> product. Why not simply use ExtFile <http://www.zope.org/Members/MacGregor/ExtFile>? Because ExternalFile supports pointing to a file "in situ" like a symbolic link, rather than copying it into some central repository directory. This may not seem like a big deal, until you consider that those files might be stored in a revision control system like CVS. ExternalFile gives you the ability to create a Zope object that points to a file in, for example, a CVS sandbox for its content. This new release is compatible with CVSFile-0-7. It also features "workalike" capabilities. ExternalFile can behave like any of the following: * DTMLDocument * DTMLMethod * Image ExternalFile is usable by itself. It is also the base class for CVSFile <http://www.zope.org/Members/arielpartners/CVSFile>.

RE: [Zope-dev] symbolic link patch
by Bjorn Stabell 18 Feb '02

Well, this would be similar to the approach used by the PortableHole product. It's more like a hard link than symbolic link; if you run your site through ZSync, ZSync will unwind all the links and make separate copies. -----Original Message----- From: Maik Jablonski [mailto:maik.jablonski@uni-bielefeld.de] Posted At: Monday, February 18, 2002 23:26 Posted To: Zope Developer Conversation: [Zope-dev] symbolic link patch Subject: [Zope-dev] symbolic link patch hello, i found this "patch" for creating symbolic links within zope: http://lists.zope.org/pipermail/zope-dev/2001-August/012711.html <snip> - edited CopySupport.py - copied the manage_pasteObjects method to a manage_pasteMonikers method - commented the #ob=ob._getCopy(self) line (the duplicate object part) - added a "Paste Ref" button to the lib/python/OFS/dtml/main.dtml file that calls the pasteMonikers method </snip> it seems to be great for my purposes & works fine & i plan to use it on a production system. has someone any information about problems with this kind of "patching"? something like breaking the database in long terms or even more ugly? thank you, Maik -- Maik Jablonski Zentrum fuer Lehrerbildung Universitaet Bielefeld Germany _______________________________________________ Zope-Dev maillist - Zope-Dev(a)zope.org http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

python10 digest + articles at pythonjournal.cognizor.com comprise PythonJournal 2(2)
by editor＠pythonjournal.com 17 Feb '02

17 Feb '02

Python Journal new issue 2(2) is out and about at pythonjournal.cognizor.com with articles and a fairly detailed digest of the content of the 4 very full days of the 2002 Python10 conference. Focus in the articles of this issue is on deepening understanding of how python works -- recursion, PySpy. First -- The pythonista thinks about repeating functions: Alternative recursion methods with iteration splitoff auxiliaries, having different oopses and efficiencies. Then -- Inspect your own pet python's looping and leaping. In realtime! Tutorial on Malcolmson's PySpy shows what documentation ;) looks like inside out, how basic program structures including recursion vs. iteration really slither along. Screenshots, congeners (and cf. inspect.py). PySpy's 5th generation architecture mixes several programming languages like many of the python10 works. Expand to the level you want, then watch the changing of your variables and function calls as python proceeds along its train of thought.... With its introspection, PySpy teases us with the possibility of python consciousness. Great study tool. NOTE: Usually at <A HREF="http://pythonjournal.com"> http://pythonjournal.com</a>, look for it presently at <A HREF="pythonjournal.cognizor.com">***pythonjournal.cognizor.com***. NB. Dr. S.

Zope 2.4.4b1 dumps core
by Dario Lopez-Kästen 15 Feb '02

15 Feb '02

Hi all! I am sorry to report that Zope 2.4.4b1 dumps core. I have filed a bug issue to the collector, and I am also seeking advice on possible ways out of my misery :) I also have attached to the collector issue two tracebacks from two different core dumps. Here is the setup: Zope 2.4.4b1, source release Python 2.1.2 source w/o pymalloc RedhatLinux 7.2, kernel 2.4.7-10 on an P4 machine We use the following products Formulator 1.0 .1- sligthly modified by one consultant LocalFS, latest Transparent folders, latest ReplaceSupport, latest Stripogram, latest DCO2, latest from CVS We have a lot of Oracle operations going on on each request, and we use a *lot' of PythionScripts. Any ideas on what might be wrong? /dario - very, very weary of these core dumps. - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services
