Hi all, Zope 2.1.0 beta 2 has been released. This release includes fixes for issues found in beta 1, an updated load_site.py script and Martijn Pieters' patches to implement try/except/else and try/finally constructs in DTML. Unless something major comes up, this will be the final beta before 2.1.0 final. You can download binary and source distribution of Zope 2.1.0 beta 2 from the Zope.org website: http://www.zope.org/Products/Zope/2.1.0b2/ Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

RE: [Zope] xmlrpc calls require string results?

It looks like XML-RPC is trying to do something kind of useful with error messages. It would be better if its exception method didn't throw away the exception type, but that's a minor issue (that I may come up with a patch for later). But the exception method always returns an XML-RPC Fault object -- I'm getting back ProtocolError objects. Looking at the sources gives me a hint: ZPublisher/Publish.py defines two methods: - 'publish_module' catches an exception and uses the response object's exception methods to handle it. - 'publish' catches an exception and looks for an 'err_hook' method in the module_info. Is it possible that publish is being used where the author of xmlrpc.py expected publish_module? If so, what/where would need to be changed to create an err_hook to handle this?

And a possibility to set such style defaults. This is what I am thinking too.

No, I did not give the option to remove them. I should have them by next release. Thanks for the feedback Hannu Pavlos

What's the problerm?
by Victor.Zhai＠ogilvy.com 16 Nov '99

Hi, I have replace my old zope system to Zope-2.0.1,And then appear some problerm. A user have been set up in the Root directory "acl_users" and I want to ftp to ZServer with it.But when pass the Username and Password.It cannot list the root dirctory.(Permission denied). I give this Local Role the Manager's above Owner right. But It can work properly within the first ZOpe version. Can some one help me. Thanks a lot.

Namespace funkiness
by Thomas Marsh 16 Nov '99

16 Nov '99

Hi Zope-dev, I have a dtml method, "A", that calls another dtml method, "B". Now, B has some <dtml-var blah> calls in it. B works fine on its own, but when A calls B, for some reason B cannot see blah (a property set in the root folder). I see this behaviour a lot. Can anyone explain it? --thomas -- Thomas Marsh Email: tmarsh(a)point-one.net Phone: (512) 381-6457

How does it call it - with <dtml-var B>? Or with <dtml-var "B()"> ? If the latter, you'll need to pass the request and namespace through to it. Something like <dtml-var "B(REQUEST,_)"> Anthony

Deleting a role doesn't remove associated permissions
by Andrew Wilcox 16 Nov '99

Yikes! Delete a role, and the permissions grants to users who are in that role remain. But the role or the permissions are no longer displayed, so the fact that someone has permission for a resource is hidden!

Possible to share zclass properties by subclassing?
by Andrew Wilcox 15 Nov '99

15 Nov '99

I have several ZClasses I'm creating, and they share a number of common properties. Oh, I said, why don't I make an abstract ZClass for the common properties, and subclass my other ZClasses from that? But, oh well, the superclass view doesn't show up in the subclass manage screen, and I don't see the superclass property sheet as an option to select in the subclass "Views" tab. Am I off base here? Is there a way to share common properties? How should I do this? Thanks! Andrew

Re: [Zope] Cheap LINUX Zope host?
by Sam Gendler 15 Nov '99

The biggest issue with SCSI is not so much performance any longer, but reliability. IDE drives have been traditionally targeted at the consumer market, while SCSI drives are aimed at the professional/server market. If you look at the Mean Time Between Failures numbers for the two types, SCSI tends to have been designed for higher reliability. That said, however, I have only ever had 2 IDE drives go south on me, with 0 scsi over the course of about 10 years. Those numbers are close enough for me, usually. Drive throughput tends to not be a huge issue with webservers, since servers spend most of their time seeking from one small object to another, not streaming enormous files to a network socket. With seek times anywhere between 8-14ms, and average object size somewhere around 8-15KB, if every object requires only one seek and one read from the disk, you can still only get about 70 transactions/second (assuming the read is instantaneous, which it isn't), which is only about 1 MB/second throughput. Therefore, it is much better to use multiple, slower drives, and distribute objects across multiple machines. Unfortunately, the data in zope is all stored in a single file, so this cannot be done. RAID is not much of a win, either, since raid increases throughput, but does nothing to improve seek time (it might even make it worse). You will be MUCH better off with more memory for buffering objects, to prevent disk access at all, rather than a fast drive. On a zope-dev note, I have a variety of solutions that would allow zope to distribute objects across multiple physical hard drives, that should not be too difficult to implement, if anyone is interested. I don't have time to play with such concepts myself until next year. --sam tommy_b(a)my-deja.com wrote: > Oops, I'm going to use LINUX as the host OS. > > I've done a bit of research on using SCSI. IWill & Tekram put out SCSI3 cards under $70 (according to http://www.pricewatch.com) Anyone use these guys? However, I'm not sure a cheap/close-out SCSI drive will match the performance-to-value ratio to a new ATA-66. http://www.storagereview.com has lots of drive tests that leads me to this thought. If I was spending more than $1000 for a new system, I'd go SCSI for sure. I need to keep below $700, but SCSI is one of my first planned upgrades. Is SCSI worth me getting a old used system with 64MB of RAM & slapping a SCSI card into it, or should I go for a new (dual) Celeron with 128MB? > > Has anyone actually done performce tests with Zope & SQL to compare what component has the most impact for a _cheap_ system: CPU, memory, or HD throughput (ATA vs SCSI)? > > Thanks for Stephan, Jim, & Nitin for the replies! > -- > > On Sun, 14 Nov 1999 18:28:56 Nitin Borwankar wrote in "Re: [Zope] What to buy for cheap Zope host?": > >tommy_b(a)my-deja.com wrote: > >> I'm building a computer to train & test Zope.

However this may take you into the next price point segment ~1000$. I have found there are good bargains on SCSI drives to be had on eBay and ONSALE auctions - go for new and 7200RPM or more. > > --== Sent via Deja.com http://www.deja.com/ ==-- > Share what you know.

How do I correct this? You can acquire REQUEST: def __str__(self): req = self.REQUEST before using the __str__ of your object, stuff what your looking for in REQUEST (it it's not allready in there). -Michel
