Zcatalog searches
by Brian Ling 20 Jan '05

20 Jan '05

Hi all, I've setup a site search using ZCatalog and ZCTextIndexs that's happily doing what I want, but I'd like to take a stage further. Is there a way using the ZCatalog Brain objects returned by the ZCatalog search to get the text that actually caused the match? I'm trying to end up with a preview of the area of the content that caused the match, or is a different approach needed? The only way I can think of doing this at the moment is to get the actual content object via the ZCatalog brain object and then re-run a regex search on the content, pulling out the text around any match. This just seems the wrong way forward is there a better way? Thanks for any pointers, I'm still very much in the newbie class at present.

You can also have a look a SpeedPack to speed up TAL. See : http://psyco.sourceforge.net/ to download and install psyco And then see : http://sourceforge.net/project/showfiles.php?group_id=55262&package_id=10732 6 To only use TAL optimization, you change : PATCH_CMF = True To : PATCH_CMF = False in config.py This works fine on Zope 2.7.3 Pascal -----Message d'origine----- De : zope-bounces+pperegrina=lastminute.com(a)zope.org [mailto:zope-bounces+pperegrina=lastminute.com@zope.org]De la part de Chris Withers Envoyé : jeudi 20 janvier 2005 10:44 À : Robert Hill Cc : zope(a)zope.org Objet : Re: [Zope] TALInterpreter Performance Robert Hill wrote: > Hey all, > > I just installed Zope Profiler to check out the performance of my pages and I noticed that I have a few bottlenecks on TALInterpreter calls that I'd like to clean up.

question on objectValues
by Wombie Tomek 20 Jan '05

20 Jan '05

I've trying to write a little dtml method that will out put a list of images in a given location using a variable "path" with is passed from a form. ?path=photos1... but haven't had much luck because it doesn't seems to interpret the variable i want to be a path. if i put the path directly into the program ie "photos1.objectValues()" it works. but i need it to be feed from a variable path. <dtml-in expr="path.objectValues('CMF ZPhotoSlides')"> <folder path="wombat/&dtml-id;/" name="&dtml-title_or_id;" amount="<dtml-in expr="objectValues(['CMF ZPhoto'])"><dtml-if sequence-end><dtml-var count-description></dtml-if></dtml-in>"/> </dtml-in> this should simple ;-) but i'm missing something. thanks... holden

20 Jan '05

Hello Zope-Users Does anyone has a workaround for http://zope.org/Collectors/Zope/569. I´ll parese the cookie by an apache module. The module checks the cookie and "says" it´s not valid I think this is because the cookie is quoted. Any hints? thx christian

20 Jan '05

i have what i hope is a fairly easy question that's been alluding me for a few hours. i've been trying to rewrite a little script i wrote in php long ago. i need to have a script, which returns an image once it decides it exists... the only thing i don't have worked out is how to do something like this: <dtml-var RESPONSE.setHeader('Content-Type','image/jpeg')> readfile(img+?size=thumb); <<----not sure how to do this, this is from php img being a path given through the url: ie ?img=somefolder/someimage.jpg thanks, holden

Memory and Large Zope Page Templates
by Santi Camps 20 Jan '05

20 Jan '05

Hi all, I'm trying to understand some questions about Zope and Memory management. I've configured a Zope with minimal Cache settings: 100 objects of cache, 4 threads and 20 Mb of ZEO Cache. The Storage is a DirectoryStorage of 4Gb. Monitoring the Zope process, all is running fine: it takes about 30 Mb of RAM. I've see that just 2 of the threads are working. The problem begins when I execute a report. The report is a PageTemplateFile that calls a method to obtain a list of processed results and send them to the user. It takes some time of process, but it works fine. What I don't understand is why, after this report, Zope is taking 120 Mb of RAM !! Too much for the cache I have. I've look for for a memory leak, showing refcounts in method like this: def _get_refcounts(self): import sys import types d = {} sys.modules # collect all classes for m in sys.modules.values(): for sym in dir(m): o = getattr (m, sym) if type(o) is types.ClassType: d[o] = sys.getrefcount(o) # sort by refcount pairs = map (lambda x: (x[1],x[0]), d.items()) pairs.sort() pairs.reverse() return pairs But there is nothing rare. I can see how the refcounts of some objects are heavely incresed during the process of the report, but when finished they are freed. But RAM of the Zope process don't decrease. Anybody have an explanation ? It's recomended to run this kind of reports in a new process ? In this case, there are any products to help this way ? Thanks in advance Santi Camps

Mailman integration with Zope
by zope-list＠mcvfifesanddrums.org 20 Jan '05

20 Jan '05

I asked this on the Mailman list, but got nothing but crickets (come to think of it, maybe I should have asked on the developer's list....) Is there any ongoing, current work on integrating Mailman with Zope? I read something somewhere that said there was such a project, but I can't find any recent work or activity. I currently use Mailman for my mailing lists and am embarking on rebuilding a Zope/Plone based site. Integrating it with Mailman would be ideal.

RE: [Zope] http header question
by Nathaniel Wingfield 19 Jan '05

19 Jan '05

OK, I found the solution and it's really wacky. Apparently IE is misreading the header, and if the word "attachment" shows up anywhere on the Content-Disposition line, including in the file name itself, it will spawn the dialog. For example, the following will cause IE to launch the open/save/cancel dialog every time: Content-Disposition: inline; filename="spb_bar_codes_attachment.pdf" While the following will launch the plugin every time: Content-Disposition: inline; filename="spb_bar_codes_xyz.pdf" -----Original Message----- From: Phillip Hutchings [mailto:sitharus@gmail.com] Sent: Wednesday, January 19, 2005 3:50 PM To: Nathaniel Wingfield Cc: zope(a)zope.org Subject: Re: [Zope] http header question On Wed, 19 Jan 2005 12:24:25 -0500, Nathaniel Wingfield <NWingfield(a)dixon-hughes.com> wrote: > > My application streams pdf files from disk (not zodb) to the user, and I've > been writing the http header more or less manually.

I had this problem with PHP powered site. IE would always ask to save and never display with the plugin. Even when the headers were identical it wouldn't work, but everything other than IE worked. I just ended up serving directly with Apache. A quick thing first, the Content-Disposition header should look like this: Content-Disposition: inline; filename="attachment.pdf" to make IE display in the PDF plugin. -- Phillip Hutchings http://www.sitharus.com/ sitharus(a)gmail.com / sitharus(a)sitharus.com ID:[{20050119155530.24590.7625540730-66.208.180.43}] _______________________________________________ CONFIDENTIALITY NOTICE This e-mail is intended only for the addressee named above.
