September 2000 - Zope

Not like ASP complaint - any good answers
by Sean McGrath 04 Sep '00

04 Sep '00

All, I have had a number of e-mails from developers using Microsoft ASP in recent days. The paraphrased consensus in the e-mails is that the external methods/python methods approach to mixing markup with code in Zope is more clunky than in ASP where you can intermingle the two at will. Has anyone written anything on this topic I could point them to? regards, Sean http://www.pyxie.org - an Open Source XML Processing library for Python

Re: [Zope] If-Modified-Since problem again?!

No traceback, because no exception. I speak of a true rounding problem: the image is modified at "x" (expressed in seconds) Zope sends "x" converted to a date/time string as "Last-Modified" Zope receives the date/time string back as "If-Modified-Since". Zope converts it to a "long", say y. *BUT* y is not x, it is "x-1". Of cause, this does not happen for all modification times. But there are not too few of them. Dieter

Re: [Zope] Non-blocking MailHost
by Richard Taylor 04 Sep '00

04 Sep '00

I think what people have in mind (correct me if I am wrong) is something that will accept messages (for posting to the mailhost at some time in the future) and then immediately return. I guess it would spawn another process/thread to do the posting asynchronously. The problem, as I see it is how to handle an error with the posting. The user who submitted the mail is now long gone so it must be left to an administrator to pick up the pieces. Perhaps the posting routine could accept a user (developer) provided exception handler that gets called if a posting fails. It maybe better to just hand this off to a completely separate program rather than try to handle it within a zope thread.

Catalog AND Zieve
by Menard.Jean-Francois＠hydro.qc.ca 04 Sep '00

04 Sep '00

I'm trying to use the Zieve product with my Catalog to sort the results on a variable key. Since the Catalog do not return the actual objects, how can I use Zieve with it? Maybe an external method returning the object list? If so, how shold I do that?

Hi all, I am getting the following error when i try to install the portal toolkit with the ' experimental login manager support'. I am using the zpatterns version : ZPatterns-0-4-1snap1and demo portal : 0.8.2 and other products. If I create the portal with no initail member then i am able to have a portal with login manager support. But then after I have installed the portal I am unable to add a member. ?? Can i have a working snapshot of the portal toolkit with the login manager for a windows version or probably a direction as to how to go abt fixing the above problem?? -neeloy ============================================================================ ================================= Error Type: NameError Error Value: client File C:\Program Files\WebSite\lib\python\Products\ZPatterns\DataSkins.py, line 377, in _v_currentSheets (Object: wqeqw) NameError: (see above) ============================================================================ ================================================= Traceback (innermost last): File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\PROGRA~1\WebSite\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: RoleManager) File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\PROGRA~1\WebSite\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\OFS\DTMLMethod.py, line 167, in __call__ (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: Portal_add) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_With.py, line 146, in render (Object: Portal.createInObjectManager(REQUEST['id'], REQUEST)) File C:\PROGRA~1\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 337, in eval (Object: apply_wizard(REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

sending mail slow?
by Chris Withers 04 Sep '00

04 Sep '00

Hi, I've noticed that sending mail from within Zope the <sendmail> tab or mailhost.send() is very slow (like it adds a few seconds to the time it takes to get a page back from a post). Why is that? how can I make it faster? I'd thought about having the actual mail sending done in a different thread/process but I don't know how I'd do that or whether it'd be worth doing. I wonder where the slowness is coming from :S cheers, Chris

Images slow rendering problem
by Pierre-Julien Grizel 04 Sep '00

04 Sep '00

Hi, I already posted this message several monthes ago, expecting a new Zope version would fix the problem, but... I have some images on my pages (let's say 10 - not a lot), rendered either by dtml-var or a manual <IMG> tag. When I render the page on some of my LAN boxes (especially with IE), some images doesn't load at the first time. I need to reload the page to make them appear. When I monkeyly hit the 'F5' key, some images do not show again. Argl. Anoying.... The problem is worst ever through Internet. Any clues ? Is it a Zope images rendering problem ? Many thanks, P.-J.

Zope.org is soooooo slow.
by Erik Enge 04 Sep '00

04 Sep '00

Zope.org is slow as hell. A couple of days a week at least. It doesn't exactly work in favor for Zope when I try to show of Zope.org to friends, collegues or potential customers and the site won't even respond. Argh! Why is it so slow? Do something about it!

Graphics served randomly. Apache - pcgi cacheing problem
by Felipe E. Barousse Boué 04 Sep '00

04 Sep '00

Has anyone seen the following behavior: I am using PCGI with Zope 2.1.6 and Apache 1.3.9. Everything works fine except when reloading the same page, the graphics in it are not "painted" by the client browser. Checking on the apache logs, I found there is a 304, meaning the object has not changed on the web server and therefore the client should be using its local cached copy. On the Z2.log, for the same graphics requests, there are no 304's but 200's meaning Zope DID serve the graphic through pcgi. So, It appears Apache is loosing the graphics somewhere. Nevertheless, the graphic is never rendered. Weirdly this happens on IE 5.0, Netscape 4.75 and StarOffice 5.2. All browsers do have at least 5 MB of disk cache and 3 MB of memory cache. This confirms the problem lies on Apache itself. Am I right? This happens in a random fashion. I have not been able to establish some pattern. The text on the pages gets rendered fine. Any ideas on how to solve this issue will be greatly appreciated, Best regards. Felipe Barousse
