Re: [Zope] Pages Half Rendering, probably fixed in 2.2?

Maybe, you should take a 2.2 ZServer and use it with your Zope 2.1.6. I do not know, however, whether this will bring up other problems. Guess I'll just have to wait and see if 2.2 makes it go away... cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] Pages Half Rendering :(
Chris, You know, I've seen that problem before on sites like Microsoft and E-Trade. The page will be really slow to load, and I will only get part of the HTML source. But it affects images, too, so my guess is it's a web server problem rather than an application server problem. Anyone else have any ideas? - T.J. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Chris Withers Sent: Saturday, August 19, 2000 9:04 AM To: [EMAIL PROTECTED] Subject: [Zope] Pages Half Rendering :( Hi, I experienced the same weird intermittent problem yesterday that I have had on odd ocassions over the last eight months. Basically, Zope 2.1.6 returns only half a page. By that I mean if I view source, the HTML just stops at some point through the page. The point depends on the actual time, it varies... clicking reload means you get more or less of the page than last time. All very odd... what makes it worse is that it happens intermittently under certain cirumstances that I can't pin down. Yesterday was on a page that performed a ZCatalog search and returned a table of the results. It worked fine from here at NIP, but when I tried at home over dialup I got the problem. That said, I've had the same thing happen a few times in the past here at NIP, mainly where pages were raising exceptions and the error wasn't getting displayed, just some half-rendered HTML... all very confusing :S Also, totally bizarely, one of our clients had problems on the same page. Searching works fine here from NIP and at home over DSL for some NIP employees. I was trying over dialup from home but had the problem I already metnioned. However, whatever the client searched for, he got no results. The page rendered fine but it was the paeg saying 'no results could be found matching youur query'. If anyone else has experienced anything liek either of these problems, or has any idea as to what may be going on, I'd love to hear it :S cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Pages Half Rendering :(
I've seen this in Netscape only, mostly while using the management interface. I haven't been able to track it down. I wonder if it has something to do with the bug in OFS.Image.index_html that Dieter Maurer reported a few messages back. I've also had a problem where mgmt interface icons don't get loaded properly, and show up broken, but on a page reload, they get loaded properly.

I doubt that the OFS.Image.index_html bug has something to do with that: Only images and files are affected. And ZPublisher seems to magically handle the "RESPONSE" return without problem. The problem only occured, because I used: dtml-var "image.index_html(REQUEST,RESPONSE)" The dtml-var probably turned the RESPONSE object it got as return value into a string and this string seriously confused the browser (as one can understand).

Hi Chris, SentChris Withers writes: I experienced the same weird intermittent problem yesterday that I have had on odd ocassions over the last eight months.

The point depends on the actual time, it varies... clicking reload means you get more or less of the page than last time. All very odd... what makes it worse is that it happens intermittently under certain cirumstances that I can't pin down. Months ago, I met a similar problem with Zope 2.1.6: A non-deterministic amount of image data was returned rather than the complete image. The analysis revealed a missing thread synchronization between the Zope thread producing the image data and the ZServer thread delivering this data. However, I saw this problem only together with the HTTPResponse.write (i.e. streaming output), and never when a page or image was delivered traditionally. When I reported the problem, DC immediatedly answered that the problem was already fixed in CVS: the threads were now synchronized. Maybe, you should take a 2.2 ZServer and use it with your Zope 2.1.6. I do not know, however, whether this will bring up other problems. You may also look at my ZServer patch for the above problem. It definitely is not optimal, because it does not synchronize the threads but simply prevents ZServer to store large results in a temporary file. It was this concurrent access to the temporary file that led to the data loss. With the patch, I never again had problems with ZServer 2.1.6.
