[Zope3-Users] Using zope.component outside Zope 3-how to bootstrap the registries
I am trying to use zope.component (Zope3 3.0) within a Python module (not running the whole Zope 3 boilerplate). I want to register a utility. What is the correct way to setup the registries (in particular the Utility registry) in order to register utilities?

[Zope3-Users] IContainer as IReadFile in WebDav
Hi, I have the following objects structure: ISomeContainer (subclass IContainer) IPlot (subclass of IContainer) IPlotPoint (subclass IContained) IPlotPoint is rather a simple object, containing X and Y of the point I would like to provide all the IPlot's in ISomeContainer as CSV files using WebDAV, to allow easy getting the data into Excel. The problem is that for some reason WebDAV always list all IPlot's as Web Folders, not as files. I cannot make zope to list IPlot as file in WebDAV Folder. I don't know how to override this. I wrote my own adapter for IPlot, but it seems to be never called: How to wire this adapter into WebDav? Should I do that another way? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Hello Jonathan,
A quick guess:
for="zope.app.container.interfaces.Icontainer"
is
for="zope.app.container.interfaces.IContainer"

[Zope3-Users] Infrastructure Requirements?
I'm at the very beginning of what will hopefully be a successful deployment of some Zope3 apps. The big question I'm getting now from the infrastructure-minded people is what sort of hardware requirements I'll need (?) Given that I'm a bit of an Ubuntu nut, I wanted to look into a Sun server. I know that I won't need much in the way of storage, the minimum CPU and memory will do... after that I get a little lost :) If our final setup (a couple years down the line) will have something like 4-5 components all running on Zope3, must be highly available, and gracefully handle minor failures, what should I spec in terms of hardware? /me awaits flames ...

Why don't you run some load tests to determine what a single server can handle with your application. Then ask the 'marketing/sales' guys for user projections (total users, simultaneous users). Then you will have a rough idea of what you need (rough being the operative word: you may need to look at load balancing, separate application and database servers, etc).

RE: [Zope3-Users] Infrastructure Requirements?
(From my Zope 2 experience, though it should be relevant here). Building an HA architecture for Zope is pretty much like anything else ... There's very little that's Zope specific. Minimum: - 8 boxes: 2 web, 2 app, 2 storage, 2 load balancers - On the web boxes run Apache with mod_rewrite to get you to the Zope instance(s) running on the app layer machines - Use ZEO w/ ZRS on the storage side. There are ways without ZRS probably, look at the Disk Replication Block Device (DRBD) project. I still bother to try and get single CPU machines, because of the whole Python GIL vs. Thread issue, though newer linuxes have CPU affinity. How you setup the load-blanacing will depend on a whole lot of factors, notably what software we use, and is beyond this list (Besides I don't do that bit, our "infrastructure" guys do that for me). We've head great success with that setup (3 app servers however) ... Vastly improved perfromance and availability.

[Zope3-Users] Infrastructure Requirements?
I'm bound to show my naivete on this round ;-) Let's say that we take HA out of the equation and that our supposed infrastructure already has storage and web covered. The app will be used by *maybe* 50 concurrent users. I'm already pretty confident in the answer, but would I do okay with something like "Config 1" shown here: (please forgive the HUGE URL) http://shop.sun.com/is-bin/INTERSHOP.enfinity/WFS/Sun_NorthAmerica-Sun_Store_US-Site/en_US/-/USD/ViewStandardCatalog-ShowAllProducts;pgid=Ljhoa7SWrIFSR0Uo1qu2uEHihp2IWGSt?CategoryName=HID-1686398653&CategoryDomainName=Sun_NorthAmerica-Sun_Store_US-SunCatalog -- Dan Buch SmartEd Services ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

What is the correct way to setup the registries (in particular the Utility registry) in order to register utilities? I don't think you need to set up the registries. There should be a base Global Registry in place already. Quite some time ago, I used zope.component, zope.interface, and a couple of other core supporting packages (zope.exceptions, zope.testing) in a command line tool. I didn't need to do any bootstrapping. I was able to use `zope.component.provideUtility` immediately. I used packages extracted manually from Zope 3.1. I'm not sure what `zope.component (Zope3 3.0)` is like. If it's from Zope3 3.0.0, it may be radically different than what I used. I believe Zope 3.1 implemented the "Simplify Component Architecture" proposal which got rid of extraneous bits like Services, and as such may be a bit easier to work with. -- Jeff Shell ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
