Where to begin (Performance on 2.9.0 vs. 2.8.4)
by Dennis Allison 28 Jan '06

28 Jan '06

Migrating systems to 2.9.0, we have noticed "sluggish" behavior compared to 2.8.4. The 2.8.4 systems run on a dual processor AMD2600 32-bit processors. The 2.9.0 systems run on AMD dual opteron 240 processors. The dual opteron systems have much more memory, much faster memory, and faster disks. We use mysql and pound and a number of other systems. I am trying to localize and quantify the performance issue we are seeing. I have checked the raw hardware as seen by python: 2.9.0 machine: Pystone(1.1) time for 50000 passes = 1.07 This machine benchmarks at 46729 pystones/second 2.8.4 machine: Pystone(1.1) time for 50000 passes = 1.23 This machine benchmarks at 40650.4 pystones/second Running disk benchmarks suggests that the 2.9.0 machine is faster in disk operations by 10 to 20 percent. I have not yet checked raw network operations yet, but I suspect that they show equivalent performance. I believe that Zopes are working fine and that the performance problems we are seeing are in the management of network input and output rather than in the Zopes themselves. Is there some performance test I can use to characterize the Zope system itself so I can compare Zopes running on the two machines?

Security class attribute
by Peter Bengtsson 27 Jan '06

27 Jan '06

Now in Zope 2.9 I get these warnings:: 2006-01-26 14:31:45 WARNING Init Class Products.MyProduct.Homesite.FilesContainer has a security declaration for nonexistent method 'FileManagement' That's understandable because I've coded it like this:: class MyProduct(...): security=ClassSecurityInfo() security.declareProtected('View', 'FileManagement.html') setattr(MyProduct, 'FileManagement.html', MyProduct.FileManagement) In other words, I create methods after the class has been defined and squeeze them in manually. Very convenient. To avoid the WARNING message above I thought I could use declareProtected() _after_ the the class has been defined just as with the additional method; but no luck :( I tried this:: class MyProduct(...): security=ClassSecurityInfo() setattr(MyProduct, 'FileManagement.html', MyProduct.FileManagement) MyProduct.security.declareProtected('View', 'FileManagement.html') But I'm getting:: AttributeError: type object 'MyProduct' has no attribute 'security' Which I totally don't understand. To test my sanity I wrote this test script which works fine:: class _Z: def __init__(self): self.z = "Z" def declareProtected(self, *a,**k): print "++declare something+" def foo(): print "I'm being called" return _Z() class A: security=foo() def __init__(self): pass A.security.declareProtected("foo") print dir(A) Which works like you'd expect with the followin output:: I'm being called ++declare something+ ['__doc__', '__init__', '__module__', 'security'] What's going on [differently] in Zope? What am I missing? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

RE: [Zope] Can one nest macros with slots?
by Doyon, Jean-Francois 26 Jan '06

26 Jan '06

The situation: I have a "main_template" that does the looks of the site, with a "main" slot where the content goes, much like the standard templates give you. Now I have objects that behave similarly and share some interface components, so I figured I could try to create another macro, with another slot to fit inside that "main" slot, that all of the objects/content types could re-use. So I end up doing what I said below ... But that doesn't work :( I've come up with an alternative for now, though it's not as elegant as this I think ... But it'll have to do. If you care to keep reading, the details: main_template: <define-macro="master"> <... some html ...> <define-slot="main" /> <... some html ...> </define-macro> shared template: <use-macro="main_template/master"> <fill-slot="main"> <define-macro="shared"> <... some html ...> <define-slot="sharedslot" /> <... some html ...> </define-macro> </fill-slot> </use-macro> Object specific template: <use-macro="shared"> <fill-slot="sharedslot"> <... some html ...> </fill-slot> </use-macro> This works without errors, except that only the first macro "shared" comes out, the "master" one never gets processed :( I would've expected this to be recursive ... Ah well :( Thanks!

Macros are decided at compile time so that you can ask a template (which is not called) for its macros:: here/main_template/macros/master The code above would have macros being created in some other template at the time this macros is used, and I cannot imagine how they would be available. Why is a macro with whatever uses your common interfaces not suitable? You scenario is too vague for any other advice. --jcc -- Building Websites with Plone http://plonebook.packtpub.com/ _______________________________________________ Zope maillist - Zope(a)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 )

[ANN] jsonserver for Z2 version 1.1.pre3 released [AJAX]
by Balazs Ree 26 Jan '06

26 Jan '06

News in version 1.1.pre3 ------------------------ - bug fixes - more advanced Five support - base demos (quickstart) re-made with Five, besides the old five-less demos are available as well. - more advanced demos: the "Click-to-edit-title" example and a drag-and-drop shopping cart mini application. All done with plain Zope. General information ------------------- Jsonserver provides an alternative way of AJAX client-server communication on Zope. Jsonserver enables Zope to act as a JSON-RPC server. JSON-RPC is an XML-RPC replacement. It is built on JSON, a javascript based data interchange format. JSON has bindings for more languages. On the client side, the "jsolait" javascript library contains both JSON and JSON-RPC support, besides other utilities. Characteristics of this approach are: - You can bind methods in javascript to Zope methods, python scripts or page templates and call them up directly from javascript in a synchronous or asynchronous way (RPC). - Both the call parameters and the return value can be strings, unicode strings, instances of any other builtin python data type, or structures built with the combination of tuples, lists and dicts. These get marshalled transparently with JSON. - As a consequence there is no necessity to use XML to pass around structured data, you can just structure your data with python and pass it directly (but of course you also have the possibility to pass around XML). - Passing of both positional and keyword parameters allows to call up page templates with request parameters. - Full client compatibility with the Zope3 version of jsonserver, i.e. the same client code will be able to run on Zope2 and Zope3 without a change. - Five supported. This version, 1.1.pre3 is a pre-release and considered to be beta. It can be installed on Zope 2.7 and 2.8 (for 2.7 you need to install Five). It is compatible with Plone and can be used from it without restrictions. (PLEASE READ release notes for how to fix a critical Plone bug.) More information, download, and installable demo product at http://www.zope.org/Members/ree/jsonserver2 . Please report bugs directly to me. -- Balazs Ree ree(a)ree.hu

Structured Text Question
by Asad Habib 25 Jan '06

25 Jan '06

Is there any way to have multiple lines of empty space between two sections of text in a Structured Text document? I looked on Google but did not find any answers to this question. However, I did notice that others had asked the question as well. Is this a shortcoming of Structured Text? Any help would be appreciated. Thanks. - Asad

zodb queries, importing and exporting
by Cliff Williams 25 Jan '06

25 Jan '06

LEAD UP: I've got a site that I need to develop and it's a natural and obvious decision that I use zope and plone as they are what I'm familiar with and what I prefer to other CMS/Portal-wares out there. The site will have several counter parts around the globe being administered by various individuals, not all of whom are enlightened enough to realize the folly of using anything other than zope. MEAT OF THE ISSUE: The sites will be tracking dance clubs. We'll be building Types in plone (Using Archetypes) to track information about clubs locally. Each site will potentially have different database technology from the other sites. I know of 3 admins who are planning on using PHP-* + MySQL and a few others who want to use Postgress and some other front end. We want to be able to integrate the information from any one site into any other site with respect to the "club objects" in the disparate databases. I'd like to leverage the simplicity of zope's application/database model and not use SQL storage if possible but don't know how I can be able to "share" with my counterparts who are bent on using relational databases. We do not intend to leave open connections to each other's database servers. The consensus is to do scheduled dumps and push the files to the other admins who would have their own routines for integrating the data into their site. I really don't want to have to set up an SQL server. Any help/suggestions would be greatly appreciated. --Cliff
