ZCatalog Strategy
by Mark Gibson 24 Mar '06

24 Mar '06

I'm struggling to weigh the cost of getObject() vs. the cost of adding more metadata to the catalog. I'll explain my situation. I have 10,000 widgets cataloged. I do a path and date query that returns me maybe 12 of these. Then I have a choice of calling getObject().getData() on each of these, or I could add getData to the catalog metadata. Does the cost of calling getObject() for a dozen objects justify creating a new metadata field? More generally how does a large amount of metadata in the catalog affect performance of queries? The wisdom of those more knowledgeable than me would be appreciated. Mark

Screwy permissions problem has me stumped
by Kirk Strauser 24 Mar '06

24 Mar '06

My Zope server uses exUserFolder and PostgreSQL for authentication. I turned on query logging today for unrelated reasons, and noticed an almost continuous stream of queries: SELECT * FROM passwd where upper(username)=upper('kirk') SELECT * FROM passwd where upper(username)=upper('kirk') SELECT * FROM passwd where upper(username)=upper('kirk') SELECT * FROM passwd where upper(username)=upper('kirk') where "kirk" is my own username. The problem was that I wasn't logged in at the time. I traced the problem back to our main page template, which starts with: <head> <title>Example.com : <span tal:replace="template/title_or_id">Page Title</span></title> </head> Being curious, I changed my username in the PostgreSQL table to "kirk_foo", and watched as my logfiles began filling with 401 errors with backtraces like: Time 2006/03/23 13:46:38.832 US/Central User Name (User Id) ourcustomer (ourcustomer) Request URL http://www.example.com/invoices/index_html Exception Type Unauthorized Exception Value You are not allowed to access 'title_or_id' in this context as customers get messages like: Site Error An error was encountered while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access 'title_or_id' in this context Now, "ourcustomer" has full rights to the "invoices" folder and all files in it, but they can't execute the "title_or_id" method on objects inside. Also, how on Earth did my username get dragged into this? As the main site developer, I own all the objects in the site, but I don't have any odd Proxy access set up. I can't figure out why customers are trying to call title_or_id as me in the first place, let alone why it fails. Any insight? -- Kirk Strauser The Day Companies

CSS Best practises
by John Huttley 24 Mar '06

24 Mar '06

Thanks to everyone for your thoughts. In summary, no one mentioned ZStylesheets. Files are ok, but no one is concerned about hierarchies. For example having a site level look and feel with specific styles for certain areas, such as tables. I'll go with the file at the top level.. Regards, john

unrestricted pagetemplatefile?
by Jürgen Herrmann 24 Mar '06

24 Mar '06

hi! the question about "unrestricted pagetempltefiles" has come up once, i found a discussion here: http://mail.zope.org/pipermail/zope-dev/2004-March/thread.html#22094 is there such a thing yet? browsing the sourcecode lets me tend to a "no"... maybe there is a patch? how difficult would it be to implement it, any hints at which methods contain the "magic"? :) thanks in advance. regards, juergen _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Jürgen Herrmann Bruderwöhrdstraße 15b, DE-93051 Regensburg Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 WEB: http://www.XLhost.de

Hi, What is the best way of handling CSS? I've looked at ZStylesheets, but it is buggy and uses depreciated functions that will not be available in 2.10. All advice welcome, --John

Strange errors while 'make'ing
by a blob of green gelatin 23 Mar '06

23 Mar '06

Hi all, I've been checking out the archives in an attempt to find an already-published answer to my problem and have only found one thread which comes close to describing what I'm seeing. When run 'configure', there are no problems. Once I try making things, I get strange errors which I suppose are probably python-related: slimemold[52]:/tmp/Zope-2.9.1% ./configure --prefix=/usr/local/bin/zope Configuring Zope installation Testing for an acceptable Python interpreter...
