Great to see you've got it working! -----Original Message----- From: Magnus Heino magnus.heino(a)rivermen.se Sent: Wed, 23 May 2001 22:44:22 +0100 To: tmclaughlin(a)visto.com Subject: Re: Fwd: ZClassEvents ------------------- > Magnus, > Did you get this working? Yes. Sorry that you didnt get any response. I have successfully used it in two projects.

So there are actually only the last three (propertysheet_id, changes, REQUEST) and self is actually the container in a ZClass.

Zope 2.3.2 and win32 python 2.1
by richard＠bizarsoftware.com.au 24 May '01

24 May '01

Are there plans for building a python 2.1 compatible Zope 2.3.2 binary release for windows? If not, could someone please let me know what the magic is for building it? I did a search on zope.org, but found little of use... Richard -- Richard Jones richard(a)bizarsoftware.com.au Senior Software Developer, Bizar Software (www.bizarsoftware.com.au)

ZEO on SMP
by Dyon Balding 24 May '01

24 May '01

Hi, We are setting up a cluster of ZEO clients on dual processor machines. >From some experiments and from searching through the mailing lists, it appears that a single Zope process will not take full advantage of the two processors. The solution would appear to be to run two ZEO clients on each server. This, however, is causing problems. I can successfully run two Zope (non-ZEO) processes on a single machine, but two ZEO clients don't seem to coexist nicely on the Windows 2000 machine. The second client to start will accept connections, but never responds with anything. Zope: 2.3.2, ZEO: 1.0b3, Windows 2k for clients, Linux and Windows 2k for storage server. Is there a better solution? If not, has anyone come across this problem? Any pointers appreciated -d

getPersistentItemIDs not cooperating?
by Steve Spicklemire 24 May '01

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

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
