Counting threads
by Peter Bengtsson 23 Jan '08

23 Jan '08

Perhaps I'm wrong but I suspect that a Zope I'm running is dying because of running out of threads. They probably die when being designated to open an external relational database connection or something dodgy. What are my options for monitoring and debugging what zope's threads are doing? Is there a simple tool to just get a simple readout of how many threads are busy? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

compile time optimizations for python
by David Bear 20 Jan '08

20 Jan '08

are there any compile time optimizations for python that would also help optimize zope? shared libraries? threads? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

Re: [Zope] Zope ZMI Templates

The other important difference between ajax loaded pages and iframes is that when you click on a link within an iframe page, the returned page is loaded into the same iframe. If I am not being clear, please check out this png file. <a href="http://medicinebrain.com/iframe.png"> http://medicinebrain.com/iframe.png </a> In this png I did a search for DML Docs within a tab panel and the search results are loaded into the same tab. BTW, I would like to simplify the zmi even more for my users. I want to hide various tabs (eg. security, find, etc) and I want to restrict the number of products they are shown in the drop down box for adding to a folder. However, I still want to offer complete zmi functionality to the overall administrator. I can probably hide the security tabs using css (the overall admin won't load the css sheet) but how can I control the products displayed to a user in the folder view of the zmi?

Plone middle aligns all colums
by Lars Hohmuth 17 Jan '08

17 Jan '08

I have a weird problem with our Plone 2.5.3 test site after a new designer took over. Plone now middle aligns the content column and the portlets in the slot on the center line, instead of on top. -------------------- --------------------------- | Left-slots | | | center | | --------------------------- --------------------- We can sort of fix this by manually adding vertical-align: top; in the css. But my designer claims that he caused this by "changing a setting in Plone or the ZMI" and doesn't remember which one. Since it's not on the production site, it's not a life and death situation, but any suggestions what might cause this are gratefully accepted. Google and the Plone site search yielded pretty much nothing. Thanks, Lars Hohmuth

Zope ZMI Templates
by Jurian Botha 17 Jan '08

17 Jan '08

I'm currently developing some customized ZMI pages and I was hoping someone could give me some insight into what the best way would be to do this. I see that Zope 2 uses dtml methods to build the standard ZMI pages but as far as I know (Zope 3 wise) I should rather be using Zope Page Templates to build the pages. I would also like the product to gracefully move on to Zope 3 in future, so that should be taken into consideration as well. Are there perhaps some existsing templates for ZMI that can also be used with Zope 3? -- View this message in context: http://www.nabble.com/Zope-ZMI-Templates-tp14734109p14734109.html Sent from the Zope - General mailing list archive at Nabble.com.

lambda's in external methods
by David Bear 16 Jan '08

16 Jan '08

In the zope 2.7 book it mentions that an optimization technique for external methods is to compile regular expressions in global scope to the module. The re's will then be compiled at zope load time. I am wondering if the same holds for lambdas. I created some simple filters using lambdas. I defined them in the functions where I use them. Is there any advantage to defining them globally to the module? Are there any gottcha's with globally scope objects? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

NamedTemplate.__call__ not returning anything
by Maurits van Rees 14 Jan '08

14 Jan '08

Hi, I have some code where I try to get a named template and render it and if it fails I render a default template instead. But this fails, presumably because the __call__ method of NamedTemplate does not return anything. From zope/formlib/namedtemplate.py (Zope 2.10): class NamedTemplate(object): def __init__(self, name): self.__name__ = name def __get__(self, instance, type=None): if instance is None: return self return component.getAdapter(instance, INamedTemplate, self.__name__) def __call__(self, instance, *args, **kw): self.__get__(instance)(*args, **kw) I seems strange to me that __call__ does not actually return anything. Is it just me? Now, I have some other code where NamedTemplate is working just fine, so there is probably nothing wrong with this __call__ method. So can anybody tell me what is wrong with my following code then? class Renderer(base.Renderer): default_template = ViewPageTemplateFile('vocabularyportlet.pt') def render(self): """Render a named template or the default template. """ template = NamedTemplate("test.vocabulary") try: output = template(self) except ComponentLookupError: output = None # Even if the component lookup works, output can be None. if output is None: output = self.default_template() return output The line "output = template(self)" fails with a ComponentLookupError unless a named template with the name test.vocabulary exists. But when that template is found, output is still None. In case you want to see the entire code, this is in a Plone portlet that I am developing: http://svn.plone.org/svn/collective/collective.portlet.vocabulary/trunk/col… And actually, the tests that I added pass when I change the NamedTemplate.__call__ method to return the value that it just got. So should that method be changed or is there a different way to do this?

Problem with buildout
by Alex Turner 14 Jan '08

14 Jan '08

I am building a plone3 site using buildout, but I've noticed that the scripts in <path>/parts/zope2/utilities and <path>/parts/zope2/ZODBTools have a different interpreter. So much so that the scripts in ZODBTools don't work on my system because they are trying to use a python that doesn't exist. Alex
