[Zope-dev] Re: Weird IndexableObjectWrapper + TopicIndex + aq_acquired interactions.
OK, so, for some reason some CMF objects fail when being indexed because they are wrapped in an aq wrapper that wrapped an IndexableObjectWrapper that wraps another aq_wrapper. And sometimes, the same object do not fail in otehrwise very similar situation. *sigh*. So for example, this works fine: container._setObject(id, ob) ob = container._getOb(id) returns to the workflows constructInstance method yadayadyada ob.indexObject() All if fine. And this fails: container._setObject(id, ob) ob = container._getOb(id) ob.manage_permission( permission_to_manage='Access contents information', roles=ACCESS_CONTENTS_INFO_ROLES, acquire=0) returns to the workflows constructInstance method yadayadyada ob.indexObject() Now, it only fails around every second time. Mhm. Nope, not everytime. It's regukar, a unit test will fail on the same places both times, but *exactly the same call* will still fail about every second time. Hurray. I'm so happy this problem is so easy to track down!

Now, in our case, the object is an IndexableObjectWrapper, wrapping an Acquisition wrapped object. So, aq_acquire will Acquicision wrap the IndexableObjectWrapper, with the result that the object being used now has no context! Really? What is the aq_parent that was used when wrapping the object? It is context of the IndexableObjectWrapper. The context of the indexable wrapped object does not change. ... Then, it passes this to validate, who in turn passes it to allowed, who check that the object has the users user folder in it's context. And it hasn't, because it has no context. *blam* You get an AuthorizedError, and the object does not get indexed. Where does the context come from used when aq_acquire acquisition wrapped the IndexableObjectWrapper? The best way around such problems would probably by to make IndexableObjectWrapper a public class. -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

RE: [Zope] Zope scalability / efficiency question
I did some tests a few years back, basically that came out such that you run the number of zope instances as you have CPUs. I was able to get double the performance of a single instance on a dual cpu server when adding a second instance. On a single CPU server, I found that the number of requests the server was able to render was cut by nearly 50% +/- when adding a second instance. My rule for building out ZEO Client servers is: Single CPU - Single Zope instance Multiple Processors - # CPUs == # of Zope instances Make sure you have enough ram if you're running multiple instances. The number of sites you can run from a single instance without cache problems really takes some localized knowledge of how your instances are performing. I run *lots* of sites from a single Zope instance without splitting them off at the load balancer into different mini-pools. I do this because I can, but if I was performance challenged from, say, cache flipping, I would definitely do this. You could likely better off if you ran all of your sites within a single instance (spread across multiple multi-processor machines with enough ram (2 - 4 GBs should do?)). It's a tough question to answer with much precision without intimate knowledge of what you're doing and how your systems are performing. If they're in the same zope instance, managing them as separate entities is difficult. Your application and maintenance of these sites might be the best determination for how you should factor the instances across your hardware.

Re: [Zope] Multiple ZODB for virtual hosts with ZEO
David Pratt wrote at 2005-9-17 13:07 -0300: Is it possible for ZEO to be configured with multiple databases, This is still possible but might go away in future. Then, you would use more than a single ZEO; one ZEO per database, to be precise. Any ZEO client can connect to any number of ZEO servers or (currently) storages on one or many ZEO servers. one for each virtual host similar to creating a ZODB mount point for an instance so if there is a problem with a site's database it is limited to a single site and that individual backups can be made of each ZODB? You can do this -- without ZEO, with a single ZEO (and multiple storages) and with many ZEOs. In fact, this feature has nothing to do with ZEO but results from mountability. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Multiple databases/instances
I'm working on the scalability aspect of Zope, and am trying to see what the best practices are for creating multiple databases or multiple Zope instances. I am using ZEO and have allowed for multiple databases (Data.fs files) by editing zeo.conf just to try that out, because our current database is getting very large. The way I understand it, ZEO allows the work load to be distributed among multiple clients when you are getting a lot of hits, but does not address the issue of having a very large database for which it may slow down. So for this you would either create multiple instances of Zope/ZEO which each have their own database, or you would just create multiple databases within a single Zope/ZEO instance. Is there what is considered a best practice as far as choosing one of these options? Is there a database size I should try to maintain by distributing my Plone sites among different databases - or maybe just have a separate database for each? Or perhaps I am way off...

Very educational, thanks for the replies!
I didn't understand Dieter's comment until I tried Axel's suggestion.
It apparently works by adding a theSecret method to the Folder
class and derived objects including the root App object.
i.e. you can visit http://localhost:8080/theSecret and (if the method
has a docstring) you'll see 'A hobbit!'.
I have to say that's pretty darn obscure behavior.
It's the antithesis of self-documenting, and I've never seen it used
before. Is this documented somewhere?
I see one example of it in OFS/tests/testProductInit.py...
Also, AFAICT there's no way to declare security on that function.
(which is OK in this case since I wanted something 'public' anyway).
Anyway, in the end, I followed neither suggestion, since I don't want
either to pollute the Folder (class) namespace, nor do I want
to register a constructor that isn't really a constructor ...
the former would be obnoxious to users who install my product, the
latter seems likely to confuse whoever has to maintain this code
after me!
Instead, I bit the bullet and rewrote the offending part of the
UI as a PageTemplateFile; it wasn't much work after all and I can
leave the rest as DTML for now. I like this solution because
client code (the template) has to explicitly look up the function
via the 'modules' mapping.
