I was hitting the front page of a CMFDefault site because I had one handy on my dev box. (but I should try Plone for this :=) I wasn't able to see any consistent performance difference.

Re: [Zope-dev] RAMcache and container vs. context
A TALES expression may be prohibitively expensive in any case, no matter how simple it is kept. Please make sure to do some comparative profiling. Cache keys are recomputed on every call of the script, AFAICS. The thought of doing this in restricted Python makes my skin crawl. Stefan On 26. Mai 2005, at 09:12, Chris Withers wrote: Paul Winkler wrote: I kinda wish the RAMCache manager allowed other things than REQUEST variables for differentiation. Arbitrary TALES expressions would be nice. Then we could get rid of this hard-coded gunk and get the same effect by having context/getPhysicalPath as one of the expressions. But of course then you'd have the opportunity to kill your cache performance by making the expressions too expensive. Ah well, TANSTAAFL and all that. I'll probably just drop the idea. I still think it's worth it.

[Zope-dev] Re: [Interested?] New use for Zope+CMF+Archetypes -- startup time improvements
Dieter Maurer wrote at 2005-5-13 19:26 +0200: ... high Zope startup time ... To overcome this obstacle, we tweaked Zope and fixed Python's import mechanism such that Zope now starts either out of a ZIP archive or as a frozen application. ... In more details, we did: * implement a package for a new kind of urls pypackage: for package relative access to resources. The package monkey patches Python's open, os.listdir, os.stat to provide transparent access to pypackage: identified resources. It currently support package relative access for packages loaded from the file system, from a ZIP archive and from the executable itself (i.e. frozen packages). In the last case, the resources are in a separate ZIP archive. This package might be interesting for Python as a whole as it is not Zope specific. I have now released this part as independent Python packages dllimporter and packageresources. You can find them via http://www.dieter.handshake.de/pyprojects In case, they should be included into Zope, I would give them a dual license (my own BSD-like and ZPL). -- 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 )

[Tim Peters] OTOH, defining importing a utility function-- say, safehasattr() --would make it all explicit. That's what ZODB does. [Paul Winkler] OK. (BTW, I just went grepping for this safehasattr() in zope 2.7.6's ZODB and didn't find anything. What's it called?) No such thing in ZODB 3.2. In 3.3+, it's called myhasattr, and is imported from ZODB.serialize. It should grow a saner name and move to ZODB.utils instead: def myhasattr(obj, name, _marker=object()): Make sure we don't mask exceptions like hasattr(). We don't want exceptions other than AttributeError to be masked, since that too often masks other programming errors. Three-argument getattr() doesn't mask those, so we use that to implement our own hasattr() replacement. return getattr(obj, name, _marker) is not _marker There are ~700 calls to hasattr() currently in the Zope core (ouch!). Are there cases where the current use of hasattr() is considered safe? Almost certainly, although who knows which? I don't. As a general matter, it's hasattr() applied to a _persistent_ object that's especially nasty. Asking whether a persistent object has an attribute can invoke an arbitrary amount of code, including network activity to fetch the object's state, and potentially raising (say) ReadConflictError or assorted socket errors. It's Bad to hide those. Or since it's broken by design, should we replace all 700 calls with this hypothetical safe_hasattr()? Spend an hour analyzing each one 0.9 wink.

Re: [Zope-dev] Re: hasattr implementation for Zope?
[Jim Fulton, on cell dereferencing's (lack of) speed] This is amazing. Really amazing. I stand corrected. Well, there's no mystery if you look at LOAD_FAST and LOAD_DEREF in ceval.c; LOAD_DEREF is slower wink. The relative speed of approaches changes across Python releases too. For example, module global lookup benefited enormously from a long string of heroic optimizations in Python's dict implementation. I consider a difference under 10% to be in the noise, and clawing for one as likely to become a pessimization as to remain an optimization under the next release; e.g., there are some obvious ways to speed LOAD_DEREF (although I don't think anyone at present cares enough to work on that). ___ 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 )

We're getting the usual timing results here: it's a cross-platform, cross-release crapshoot.

Re: [Zope] DTML in Zope 2 vs Zope 3
Wow, thanks for the replies guys. It's good to hear I am not the only one who likes DTML. Tino, thanks for the explanations. I have some thoughts below on that, and keep in mind, I am questioning from my own ignorance. Tino Wrote: The major drawbacks of DTML are: - one namespace (with transparent layers) One namespace? Why do you need more? I havent had any problems with one. Can you give some examples of why this is important or how it would be useful? - confusing naming of tags, like dtml-var which really is dtml-print or something Well I realize that it could be named something else, but it never occured to me. I dont think it's confusing. I mean, in DTML you use 4 tags more than any other, IN, VAR, IF, and CALL. Simple. And if there is one thing I have learned over the few years I have been programming, it is to keep it simple. Simple works. - and the extra tags for flow control, but probably the dtml fans can live with it. Yeah, simple. We can live with it, particularly since we can call more detailed functionality from Python. - peoples practice to use dtml-var foo even inside html-tags attributes, where dtml-foo; should be used. Hmm.. Never thought of that one as I too just use the full dtml-var foo. I can see now that it might make readability a little better to use dtml, but is there a technical reason for using it that way? Thank you again for your input Tino. I can understand the need to take Zope to another level, its the nature of things to keep them growing. And changing Zope to fit the needs of large scale applications is good, I just hate to see the sacrifice of the smaller apps needs. I probably will never get to work on enterprise class systems, in fact I really dont want to, but Zope works beautifully for the small web apps and that's what I want to work on. I wonder what the ratio is of Zope users who use small apps to those who do large apps? Thanks again!

Re: [Zope] DTML in Zope 2 vs Zope 3
Using DTML from WYSIWYG editors is definitely a drawback. But, how many of us use them for doing our work? I might use Dreamweaver to clean up my sliced web template, but soon as I start my Zope work, it's all Crimson Editor coding by hand to Zope. Using Dreamweaver actually slows me down, it's easier to just code it. However, from a newbie perspective, not being able to run my Zope content in my fancy, drag'n'drop editor really bugged me a long time a go. Saying DTML sucks is only stating your difference of oppinion. At least give us some insight as to why it sucks. Technical, usability, or even marketing reasons would be helpful. But, come on DUH? Everybody will have their preference of languages, and even the way they like to layout the code. So I understand that some of us like DTML and some dont. All that aside, DTML may be ugly, but I dont agree. I guess beauty is in the eye of the beholder. :) Well, aside from the fact that you cant use DTML in WYSIWYG editors, I still dont understand why it is not good. If it is simple, easy to use, and it does the job, and I suppose, if you prefer it, why is it not good to use? I've beaten this subject to death, so time to move on. Thanks for hearing me out.

Re: [Zope] DTML in Zope 2 vs Zope 3
Ah you are right. Just occured to me. That is kind of a pain in DTML, but I've learned how to deal with it. Makes sense. If I already have an object, say from a form submitted, in the REQUEST namespace, and I then retrieve data from sql and a column has the same name, I will have an issue. Which one is going to display in my var? I deal with this particular issue by changing my zsql method to return the column name differently, but there are other times when this may arise and it is a problem. And this causes you to have to do a bunch of messy dtml-call REQUEST.set's to set your vars correctly. I have learned how to deal with these things, but you are right, this is a problem with DTML and I can see how this exact issue helps make DTML messy and a little confusing. Great point. Thanks.

[Zope] XML Content handling questions.
Three questions, in order of importance (to me): 1) Is it possible to validate an (uploaded) XML file against a schema (currently on the Zope server)? What, if any, extra packages are needed?I want to use this in my upload forms to alert the user if their files are invalid. 2) I also need to serve up web-based forms and allow the user to create XML content based on a user-selected schema. Something like what Chiba (http://chiba.sf.net/) is targeting. Of course, though, that isn't a Python/Zope solution. Has anyone seen anything that works? At this point, installing Tomcat and Chiba is what I presume I'll be doing in a couple of weeks 3) Is there a function built-in to Zope that allows merging XML files? (ie: all the abc within a list of user-selected files). I've got an Extension that works correctly (using the Amara/4Suite packages), so an answer here is mostly for me to learn Zope better.

Personally, I'd probably just do something like::
{1,2,3}[1:-1].split(',')
This code works as expected... Thanks! :)

Re: [Zope] XML Content handling questions.
Zope itself has no native XML support. However there are some products like ParsedXML that provide additional functionality. You might also look at Silva CMS which is provides native XML support. -aj --On 27.

What, if any, extra packages are needed?I want to use this in my upload forms to alert the user if their files are invalid. 2) I also need to serve up web-based forms and allow the user to create XML content based on a user-selected schema. Something like what Chiba (http://chiba.sf.net/) is targeting. Of course, though, that isn't a Python/Zope solution. Has anyone seen anything that works? At this point, installing Tomcat and Chiba is what I presume I'll be doing in a couple of weeks 3) Is there a function built-in to Zope that allows merging XML files? (ie: all the abc within a list of user-selected files). I've got an Extension that works correctly (using the Amara/4Suite packages), so an answer here is mostly for me to learn Zope better.
