sort_on in newer versions of zcatalog..?
by Geir B�kholt Hansen 03 Apr '00

03 Apr '00

has the 'sort_on' parameter for Zcatalog changed lately?? tried some of my old methods with a Zcatalog on a CVS-zope-install, and they return : Error Type: AttributeError Error Value: 'tuple' object has no attribute 'intersection' when fed '?sort_on=someindex' Is this only in the CVS, or in 2.1.6 too ?? -- Geir Bækholt Hansen web-developer/designer geirh(a)funcom.com http://www.funcom.com

Catalog text search returns unexpected hit
by R. David Murray 03 Apr '00

03 Apr '00

I have a large catalog, and I'm performing a search on a very modest subset of that catalog (searching with a meta_type= that selects from among about 200 objects). For the most part things are working as expected, but I have at least one case where a search term brings up a particular object that does *not* have that search term in the field on which the search is performed. Has anyone else seen anything like this, and does anyone know how I can go about inspecting the guts of the catalog to try to figure out why this object is coming up when it shouldn't? --RDM

problems rendering a dtml method
by fog＠mixadlive.com 03 Apr '00

03 Apr '00

hi, here again with problems in the Translator product: inside the render() method of the dtml-localize tag i do some magic to find suitable Translators and then i ask them for the argument of the tag. sometimes this argument is a dtml method inside a subfolder and the object returned (by a default getitem()) is an Acquisition.ImplicitAcquirerWrapper. the method uses some properties dtml-let-ed above (the properties are there, i can see them in the md passed as an argument to render()) but i don't know how to pass the md to it. using something like: for t in translators: try: v = t.translate(val) if hasattr(v, '__call__'): return v(md) else: return str(v) except AttributeError: pass raise AttributeError(val) but the v(md), obviously does not work and i get an AttributeError from inside the dtml method. any ideas? federico -- Federico Di Gregorio MIXAD LIVE System Programmer fog(a)mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog(a)debian.org Don't dream it.

product creation problem..
by Geir B�kholt Hansen 03 Apr '00

03 Apr '00

trying to make Johanc's IEmethod product fit into our intranet, i modified it to inherit from DTMLdocument instead of method, and modified __call__ in it by cut'n paste from DTMLdocument and adding : std_html_header= apply(HTML.__call__, (self.standard_html_header,bself, REQUEST), kw) std_html_footer= apply(HTML.__call__, (self.standard_html_footer,bself, REQUEST), kw) out = std_html_header + r + std_html_footer return out to make it include standard_html_header and footer.. Everything works nicely, except it seems it cannot see objects outside itself.. As my header and footer references other methods in my site, things break and i get nameerrors..

Raising HTTP response codes from PythonMethods
by Itamar Shtull-Trauring 03 Apr '00

03 Apr '00

In DTML I can do <dtml-raise Redirect>&dtml-BASE0</dtml-raise> and I'll get redirected to BASE0, since the exception is converted into a HTTP response code. How can I do the same in a PM? I'm trying to get a NotModified header to be returned, aborting the transaction while I'm at it. -- Itamar S.T. itamars(a)ibm.net

problems with dtml-if
by fog＠mixadlive.com 03 Apr '00

03 Apr '00

Hi *, my Translator (ok, not only mine...) product has a big problem: it does not work inside a dtml-if tag. does anybody know if the dtml-if tag does something strange to the namespace? apparently the render() method gets called with a much reduced TemplateDict if the dtml-lvar tag is inside a dtml-if. *sigh* federico -- Federico Di Gregorio MIXAD LIVE System Programmer fog(a)mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog(a)debian.org All programmers are optimists. -- Frederick P.

Python 1.6 a1
by Stephan Richter 03 Apr '00

03 Apr '00

Hello everyone, I finally got around checking the Python site again, and what did my tired eyes see? Python 1.6 a1 is out and a roadmap for the next releases. What makes the entire subject so interesting is that Python 1.6 will support unicode and OpenSSL (in the socket, httplib, urllib). Furthermore, there will be a module called sre, which supports unicode regular expressions. What does that mean? I don't know, but maybe we have a major Zope release coming up supporting unicode and OpenSSL (ZServer)? I would love to see it, since I would not need to use Apache anymore. Due to the incompatibilities in the Python code that would mean that Zope would also be backward incompatible; does that mean it would be Zope 3.0.0? I would love if some folks from Digital Creations could comment on that. What is the plan?

XML-RPC woes
by David Brown 02 Apr '00

02 Apr '00

I'm trying to use XML-RPC in a Zope product (specifically, I'm trying to make Userland's Pike work with Zope), and when calling my functions from outside (calling in to Zope), it seems to always return a "500 Internal Server Error". Which, of course, rolls back any changes I may have made. I've seen traffic on the list about this before, was there ever any resolution? dave http://zopefish.weblogs.com/

Just some basic load tests using ab against a specific set of URLs with and without the patch would provide some not-very-scientific-but-still-useful feel for how big the win is...
