Zope and Frontier
by Philip Suh 13 Jul '99

13 Jul '99

Hi again, I'm a longtime Frontier user and now a Zope newbie. My initial interest with Zope is how it works together with Frontier, though I can see lots of other things I'd like to try in Zope as well. I'm not sure how much experience you all have with Frontier. But if anyone has tried to do work with Frontier, or has any experience in making the two products dance well together, I'd be interested in your stories. Thanks in advance, Phil

Pam, First, you're not going to like this part, but I got two replies from people pointing out that FrameMaker isn't accessable to your volunteer collaborators. I concur. You might want to explore options that would make it easier for them, such as some form of SGML. I haven't used Frame in 5 years and thus am not familiar with the file formats it can handle. Here's a patch for ZCMG.8.html, but obviously you'd have to get these changes into the frame source. I think all of them would come up if you ran the spell checker.

Scalability of Zope
by Philip Suh 13 Jul '99

13 Jul '99

Hi, I'm a Zope newbie. I've done some searches in the archives on 'scalability'. I'm currently evaluating Zope for possible use in a high traffic situation. I have seen discussion on the multithreadedness of ZODB3 (in Zope 2), which is good news. What other issues or concerns are there with Zope in regards to scalability? How have people been setting up Zope, and what's the largest Zope installation that you know of (in terms of machines, database size, and traffic)? I like what I see in Zope and hope it will be useful for my applications. Thanks for your help! Philip Suh

newbe question
by Perez, Victor 13 Jul '99

13 Jul '99

I have a site with the following structure: index_html Folder1 Folder2 ... Folder"n" And have a navigation bar method as follows: <TD colspan="3" valign="middle" class="NavBar">   <a href="http://147.1.95.251" style="text-decoration: none; color: White;">HOME</a>  |    <a href="" style="text-decoration: none; color: White;"></a>  |    </TD> As you can see, It should show only the folders that have the "publish" boolean property set to TRUE but when I set the property for one folder, all other folders gets shown, even the ones on a parent level... any ideas? - Atentamente, Victor Perez Muena Automation Support - Port Area (Los Vilos) Los Pelambres Project - Bechtel Chile Ltda.

(I'm working on an external method which is totally outside > the ZClass's Product, it just has to create a ZClass as a > side effect). Gotcha - then yes, you do need to use the Control_Panel.Products.xxx way, since the external is outside of a product.

ZServer streaming output
by Toby Dickenson 13 Jul '99

13 Jul '99

I've been comparing the streaming output of ZServer and ZopeHTTPServer , and come across two disadvantages related to the way ZServer buffers writes in memory. Firstly if the output is created faster than the client can consume it then the Zope process grows to accomodate the buffer. If the streamed output is large then this may not be appropriate. Secondly, there seems to be no convenient way to abort the method if the client disconnects part way through receiving the streamed output. With ZopeHTTPServer in this situation, RESPONSE.write would raise an exception. Is there anyway to recover some of the old behaviour under ZServer?
