Zope 296->210 page template calling prob.
by JZopeDev Kioza 06 Mar '07

06 Mar '07

Hello, I have a problem since upgrading to Zope210x that I hope, concerns "Development folks". I use a call to "custom-internal" pagetemplates in one of my products (actually they are plugins). With Zope 2.9.6, in my product I use: return _config.myPT(context={'here':self, 'request':REQUEST}) _config. is a module which initialize myPT as a PageTemplate and read-it in like so: f = open(aPlugin + '/' + myPT) myPT = PageTemplate() myPT.write(f.read()) f.close() This always worked! Now, with Zope 2.10.2svn, and the new PageTemplate machinery, this call doesn't work anymore. My custom pagetemplates are full of "here" statements in their TAL expressions and they are not recognized anymore: Here's the log: Exception Type KeyError Exception Value 'here' Traceback (innermost last): * Module ZPublisher.Publish, line 119, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 42, in call_object * Module Products.SlashAdmin.SlashAdmin, line 1204, in edit_form * Module zope.pagetemplate.pagetemplate, line 96, in __call__ * Module zope.pagetemplate.pagetemplate, line 117, in pt_render * Module zope.tal.talinterpreter, line 271, in __call__ * Module zope.tal.talinterpreter, line 346, in interpret * Module zope.tal.talinterpreter, line 534, in do_optTag_tal * Module zope.tal.talinterpreter, line 516, in no_tag * Module zope.tal.talinterpreter, line 346, in interpret * Module zope.tal.talinterpreter, line 745, in do_insertStructure_tal * Module zope.tales.tales, line 696, in evaluate Line 1, Column 0 Expression: <PathExpr standard:'here/slash_header'> Names: {'args': (), 'default': <object object at 0x2b149c76a200>, 'loop': {}, 'nothing': None, 'options': {'context': {'here': <SlashAdmin at /testpt/browse used for /testpt/www/DOMAINES>, 'request': <HTTPRequest, URL=http://intranet/DOMAINES/browse/edit_form>}}, 'repeat': {}, 'template': <zope.pagetemplate.pagetemplate.PageTemplate object at 0x2b14a55ff6d0>, 'usage': <zope.pagetemplate.pagetemplate.TemplateUsage object at 0x2b14a963fd10>} * Module zope.tales.expressions, line 217, in __call__ * Module zope.tales.expressions, line 194, in _eval * Module zope.tales.expressions, line 118, in _eval ********************************************* I have tried many combinations like using extra_context, combining self.. etc.. But I don't follow what changed between Zope version that could affect that. Surely the "context" key of "options" key (!) does not work as before. Can someone help? Tx jf

Participation on the Python Web-SIG
by Jim Fulton 05 Mar '07

05 Mar '07

I encourage people interested in Zope development to subscribe to the Python Web-SIG mailing list: http://mail.python.org/mailman/listinfo/web-sig I think we should be seeking to collaborate with the wider Python Web development community. Also, often when I discuss things on that mailing list, I feel like I'm the only Zope person present. I'd love to have more support. Also, there are a diversity of points of view in the Zope community and I shouldn't be the only one representing us. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

TypesTool speedup
by Wichert Akkerman 05 Mar '07

05 Mar '07

I'm forwarding a message from limi here, since it makes much more sense here than it does on plone-developers. To summarize it: while analying performance of the Plone 3 codebase they noticed a lot of time was spent trying to figure out which types could be added at a location. Part of that logic uses the TypesTool _queryFactoryMethod function, which goes through the dispatcher to get to the factory method for a type, which is apparently very slow in Zope 2.10, and much faster in Zope 2.9. They came up with http://paste.plone.org/13211 which is an imho somewhat evil approach which introduces a thread-local cache for App.FactoryDispatcher._product_packages. As described below the speedup as a result of that is huge. Since Zope startup is as far as I know the only time the result of _product_packages is change perhaps it would be useful to generate that result on speedup. Or perhaps to make _product_packages cache its output. I certainly do want any monkey patches in Plone for this since it should be fixed in either Zope or CMF.

The main news for the day is that we found a combination of slowness in Zope 2.10 and CMF using that method in a less-than-optimal way. The result was that rendering the content menu (the one that decides what types you can add where etc) was eating an amazing amount of time. Explained in my usual UI designer hand-wavy way, every time we load a page in logged in mode, it checks the list of Products to figure out what you can add. So, by caching this locally in TypesTool so it doesn't get looked up every time (the list of Products doesn't change with every request, after all), we get a significant speedup. Let's see some numbers of loading the front page of a fresh plone : Before types tool optimization (10 requests): Products/CMFPlone/skins/plone_content/document_view.pt 8.54s lib/python/plone/app/contentmenu/contentmenu.pt 6.26s After types tool optimization: Products/CMFPlone/skins/plone_content/document_view.pt 2.55s lib/python/plone/app/contentmenu/contentmenu.pt 0.29s That makes every logged in page over 3 times faster. I like it. :) Patch for CMFCore TypesTool included. -- Alexander Limi · http://limi.net _______________________________________________ Plone-developers mailing list Plone-developers(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plone-developers ----- End forwarded message ----- -- Wichert Akkerman <wichert(a)wiggy.net> It is simple to make things. http://www.wiggy.net/ It is hard to make things simple.

difference between OOSet and OOTreeSet?
by Chris Withers 02 Mar '07

02 Mar '07

Hi All, Wondering if someone could tell me the difference between an OOSet and an OOTreeSet? They seem to have different interfaces and yet seem to be used in similar circumstances in PluginIndexes/common/UnIndex.py... I'm looking for a set-like data structure which will likely get pretty large over time and so I don't want the whole data structure written to disk each time I add a new item to the set. What should I be using? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
