Colorz product - beta 3 :-s - bugs fixed + new method
by Max M 29 Nov '02

29 Nov '02

I have received a lot of feedback, interrest and positive comments on the Colorz product.. Thank you all. But issues showed up so I have changed it a bit. get it while it is still fresh at: http://www.zope.org/Members/maxm/productList/colorz/colorz10b3.zip/view regards max M #############################3 Bugs fixed! - I had hardwired colorz as an id into some of the dtml. This has been change. Thanks to Jerome Alet for the "patch" - Whenever a grey color was used, what should have been levels of greys actually had red in it. This is due to the Python colorsys module. I can see that it can be confusing, so I have special-cased grey colors. #############################3 New functionality A new method is added 'getcolor()' wich can be called like:: <dtml-var "colorz.getcolor(colorname='main', brightnes=50, saturation=20)"> <dtml-var "colorz.getcolor('main', 50, 20)"> <dtml-var "colorz.getcolor(brightnes=50)"> ("main" is default)

OT: Microsoft's marketing of its content management products
by Ausum Studio 29 Nov '02

29 Nov '02

Looks like as if they had renamed former NCompass' Resolution to "Content Management Server" just to be able to use the acronym 'CMS' and let believe unaware newcomers that they had been in the content management businees before the term 'Content Management System' was invented. Nasty move, indeed, but nothing that could've stopped me to smile while watching its fancy flash demo, because its funny to notice how MS does make heavy use of its marketing resources, just to make believe they are leading the industry, when we all know how PITA is to get all that stuff to work properly, just to make the things that Zope/CMF does in a heartbeat. I'm looking forward the release of to-be-cool Zope3. I'm sure I'll smile even more. :) Ausum ps. The MS demo: http://www.microsoft.com/sharepoint/evaluation/demo/CMS_SPS.swf

WebDAV & ZPT question
by Lars Heber 29 Nov '02

29 Nov '02

Hello zopistas, I tried several webDAV capable applications to use ZPTs, they usually work fine except for one thing: I have one template under Zope, and I want to reuse them in such an application by doing the following: - Open the template - Change contents - Save it back _with_another_name_into_another_directory. The new created files were written back onto the Zope server, but their meta_type wasn't ZPT anymore but DTML Document or even File, depending on the used application. Is there a possibility to set the target meta_type which Zope should use on upload? Also: Is it possible to pass "properties" from such an app to Zope? I specially think of the title property which each object should have... Who knows a Windows application which is capable of these features? Thanks a lot. -- Lars Heber T-Systems GEI GmbH Hausanschrift: Clausstrasse 3, 09126 Chemnitz Postanschrift: Clausstrasse 3, 09126 Chemnitz Telefon : (+49 371) 5359-271 Fax : (+49 371) 5359-133 E-Mail : Lars.Heber(a)t-systems.com Internet: http://www.t-systems.de

attaching files from a folder
by jonatan 29 Nov '02

29 Nov '02

hi! i would like to attach files in a folder named 'attach' here is a very basic dtml: <dtml-mime type="text/plain; charset=iso-8859-2" encode="quoted-printable"> <dtml-in "attach.objectValues()"> <dtml-boundary encode="base64" disposition="attachment"> </dtml-in> </dtml-mime> zope doesnt permit saving this: Error Type: Document Template Parse Error Error Value: Unexpected tag, for tag <dtml-boundary encode="base64" disposition="attachment">, on line 37 of send_welcome_mail if i get <dtml-boundary> out of <dtml-in>, then it works. but how can i loop over some sequence to be included within <dtml-boundary>? one more question: i would like "8bit" for content-transfer encoding. isnt there a way to use that? thanks, jonatan

RE: [Zope] My Zope is leaking memory ... Still no luck.
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 29 Nov '02

29 Nov '02

Hello everyone, Well, I'm still not having any luck tracking this down ... I've tried to keep a nice and close eye on the top refcounts, but I'm not seeing anything strange, the really big delta is on the DateTime object, as the refcount seems to vary quite a bit, but the top one is fairly stable. I will keep the LeakFinder as a last resort, as it rather dangrous to run apparently :) So, if the database object caching and refcounts are not the cause, what else could it be? So, a few questions: Could I possibly have written Python Code that would leak memory? Keeping in mind I am in no way a Python wizard? Otherwise, I'm going to turn my attention towards Psycopg, since it is heavily used. Anyone have experience running Zope with ZPsycopgDA, and has had memory usage problems? The site makes several queries per second at least, and each thread (6) opens I think 4 persistent database connnections. I'm also wondering if the fact that I asked Psycopg to use Zope's internal DateTime object instead of the mxDateTime one might be the cause, I'll try to play with that ... So if anyone has any more ideas about this, I'm open to anything!

Hello, Yup, that's right, my Zope is leaking memory, and so far, I've had no luck figuring out where it might come from. I run a Zope 2.5.0 on RedHat 7.3. I started by looking into the Python/C type modules, which I fugred are most likely to be causing this. I upgraded Psycopg to the latest version, but it's still occuring. I also use the PIL, but it is seldom used, and could not be the cause of the kind of leakage I'm seeing. Then there's a much more obscure thing, which is a SWIG interface to PROJ.4 (A geographical projection library) ... I had the author look at it, and no leaks were detected in the C library, or using the SWIG interface (Using Valgrind I beleive). My Z SQL Methods do NOT cache results (Maximum time set 0). (...) Any ideas, comments, insights, tips would be MOST appreciated!
