getPersistentItemIDs not cooperating?
by Steve Spicklemire 24 May '01

Has anyone seen anything like this? I have the following script in a Specialist: ## Script (Python) "deleteAllTracks" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## trackMaster=context.Tracks import string iList=[] for id in trackMaster.defaultRack.getPersistentItemIDs(): iList.append(id) theItem=trackMaster.getItem(id) iList.append(theItem.manage_delete()) return "OK! deleted:" + string.join(iList,',') It works.. partially. For some reason it looks like getPersistentItemIDs does not always return a *complete* list. I need to run this method several times to completely exhaust the Rack's storage. Thoughts? The only way I ever create Track objects is via a different method that is only accessed once (a long time ago!) thanks, -steve

RE: [Zope-dev] ZEO on SMP
by Randall F. Kern 23 May '01

If I understand your scenario, you are trying to run two instances of Zope on a single machine, talking to a ZEO server? That won't work :) Neither Unix nor Windows knows what to do with two processes trying to open the same port for listen. I'm surprised the second Zope instance even starts. If you want to try it, start each instance of Zope on different ports, then use some kind of ipforwarding/load balancer on the box to route connections to port 80 to either of your Zope servers (say 8081 and 8082). -Randy > -----Original Message----- > From: Dyon Balding [mailto:dyon@devcoder.com.au] > Sent: Wednesday, May 23, 2001 12:08 PM > To: Tino Wildenhain > Cc: zope-dev(a)zope.org > Subject: Re: [Zope-dev] ZEO on SMP > > > Tino, > > Thanks for your reply. > > When you say it works fine on a dual processor machine, are you saying > that a single ZEO client fully utilises both processors? or that you > are running two ZEO clients successfully? > > Unfortunately I'm currently stuck with Windows due to both political > reasons, and because we are interfacing to a large SQLServer database. > > -d > > On Wed, May 23, 2001 at 08:44:59PM +0200, Tino Wildenhain wrote: > > Hi Dyon, > > > > ZEO on a dual processor machine runs fine for me. > > I'm using redhat-linux for the server (ZEO and Clients > > on same machine) > > If you dont need strange things I would not recommend > > Win2k as server platform. > > > > Best regards > > Tino Wildenhain > > > > --On Mittwoch, 23.

ZCatalog Brains
by Chris Withers 23 May '01

23 May '01

Hi, Is it still fair game to use the data_record_normalized_score_ attibute of ZCatalog Brain objects? If so, is it accurate and meaningful? Finally, is there any way I can do the Google-esque thing of showing the snippet of the searched etxt with the words that were found highlighted? cheers, Chris

Extended DTML Sorting gone into trunk
by Andreas Jung 23 May '01

23 May '01

For your information: the implementation of the Extended DTML Sorting proposal (http://dev.zope.org/Wikis/DevSite/Proposals/ExtendedDTMLSorting) has gone into the trunk. The implementation introduces a new module "sequence" to the _ namespace. For further documentation check the online help (search for sequence) or the implementation under lib/python/DocumentTemplates/sequence. Thanks to Oleg for the implementation. Cheers, Andreas

Subclassing SimpleItem and overriding __allow_access_to_unprotected_subobjects__
by Mark Postal 22 May '01

22 May '01

I am trying to acquire the functionality of SimpleItem and the new Zope 2.2+ security model (methods are private by default) in a single class. Thus I subclass SimpleItem and override __allow_access_to_unprotected_subobjects__ as follows: class subclass(SimpleItem): __allow_access_to_unprotected_subobjects__=None __ac_permissions__=( ('View', ['index_html'], ('Anonymous',))) private = HTMLFile('filename', globals()) . . . I would expect that the 'private' method would no longer be viewable via the web. But it is. Am I missing the obvious here? Mark Postal

LeakFinder product
by Shane Hathaway 21 May '01

21 May '01

New product: http://www.zope.org/Members/hathawsh/LeakFinder This product assists in locating memory leaks in Zope code. It uses patterns we, at Digital Creations, often employ for fixing memory leaks. It provides a way to get a "controlled" refcount and the traceback of class instance creation. Instructions provided. Be careful with it, please. Shane
