nonlinear response times on multiple concurrent requests for same data
by Sean Hastings 12 Sep '04

12 Sep '04

I have a report page that when going through the maximum amount of data takes maybe 5 seconds to generate on both my Linux server and on the Windows machine I use for development. This report page is a Page Template generated from external product code. There is no external database involved - just Zope objects. I was getting weird periods of serious slowdown on my server, and traced the problem to multiple users running this report at the same time. On the windows machine, if I generate 4 requests, the time to return all of them is approximately 20 seconds or x*N response time. On the Linux machine, however, I seem to be seeing MUCH longer response times for simultaneous requests for the same data. Could this be an issue with the way in which I have Zope configured on the server? or does the Linux version do something differently? I have seen hints of "read only" transactions, but have not been able to figure out how to code these. Is there something I could do to make these read requests for the same data not interfere with each other? --Sean

dtml-in, dtml-var, javascript and keeping quotes
by Richard Rosenberg 12 Sep '04

12 Sep '04

Hello All: Is there a format code (or other way) to do the following: <script language="JavaScript"> var myArray = new Object(); <dtml-in somelist_of_strings prefix="sl"> myArray[<dtml-var sl_item>]=<dtml-var anotherlist_of_strings[sl_index]> </dtml-in> </script> Specifically, I am interested in whether there is a way to force <dtml- var> to render the quotes, assuming both somelist_of_strings and anotherlist_of_strings are both variables available through the REQUEST object. Right now I have to enclose each dtml-var tag inside double quotes, and while it works, it's kind of messy and screws things up when it comes to a different data type. Any suggestions are appreciated.

RE: Importing Products into my Custom Product....
by Bill Hewitt 11 Sep '04

11 Sep '04

I am asking this question again in hopes that maybe this time it will make more sense.... What I want to do is reuse code from one product to the next in a Python Class...... This is trivial in a ZClass, but ???? Anyway, I create a new Python Product "FOO" and I want to import the methods of another Python Product "Bar" ("FOO" and "BAR" are next to each other in the Products Directory), so I add "import Bar" into my __init__.py file for "FOO" When I do this, the ZServer complains that the module does not exist..... So, I try: "from Bar import Bar" and "from Bar.Bar import Bar" and "from Products.Bar import Bar" Again the ZServer complains that the module does not exist -even though they *do* exist right next to each other in the same "Products" Directory..... How do I get one product to use (reuse) the methods of another product that also exists in the "Products" Directory? WPH

dtml-tree status again
by Gál László 11 Sep '04

11 Sep '04

Hi! dtml-tree question again (ZopeTree is not suitable for now, because I want to build a tree from results of zsql methods) A little example to demonstrate my problem: <dtml-tree> <a href="&dtml-URL0;"><dtml-var id></a> </dtml-tree> Each link is pointing to the same page where the dtml-tree is, but when you click on any link, tree will lost its status, and it will be collapsed. Now that's what I don't want :) Version: Zope2.7.2 Lac

Import Problems - What am I doing wrong?
by Bill Hewitt 11 Sep '04

11 Sep '04

I have two Python Products, Virtual_site and Virtual_Misc in the lib/python/Products directory.... In Virtual_Site, I have a Python module called Campus and inside it, I have a Class called Campus..... In Virtual_Misc, I have a Python module called Misc and inside it, I have a Class called Misc and several methods..... I have been trying to import the methods from Virtual_Misc.Misc into Virtual_Site.Campus - but everytime I try to import I get an error.... I have tried putting the following into the module Virtual_Site.Campus: import Misc and from Virtual_Misc import Misc and from Virtual_Misc.Misc import Misc and import Virtual_Misc.Misc.Misc None of these work and I get an error.... So I tried to put the import statement into __init__.py - again no luck..... This is very frustrating to me and obviously I am missing something - IF someone out there can enlighten me, I would greatly appreciate it... TIA WPH

Is it possible to use a ZClass as a base for a Python Class?
by Bill Hewitt 11 Sep '04

11 Sep '04

I have a lot of ZSQL Methods stored in a ZClass and I am wondering if it is possible to somehow import this ZClass and use its methods in a Python Class... I've seen lots about using a Python Class as the Base for a ZClass, but nothing for the other way around.... Anyone know how to do it? WPH

webdav
by John Hunter 11 Sep '04

11 Sep '04

I have a zope server distributing files (eg microsoft word files). These files are templates and should not be editable in place by users using webdav. I want them to download them, edit them on their computer, and then upload the modified document through a web form, which will place the modified document in a new folder. This works fine on linux / osx / etc across many browsers. I am also using CookieCrumbler for authentication. On Windows computers running IE, however, when a user clicks on one of the documents, the basic authentication dialog appears even though they have been authenticated already with cookie crumbler. I've read that you can serve these documents over the webdav src port to work around this, because webdav doesn't understand cookies. I haven't tried it yet because authentication is not my primary concern. As I understand it, webdav is used so that effectively users can edit documents in place. I want to prevent this. What is the right way to achieve this? I was hopeful that by changing the "WebDAV access" and related webdav permissions so that the users don't have permission to do this I could circumvent the problem. This may ultimately work, but I still get the basic authentication dialog. Perhaps if I serve it over the webdav port and remove webdav permissions in the securities tab I can get everything I want, which is: users have read only access to the document and authentication is with cookie crumbler. I hate it when computers try and be helpful. Suggestions, please. Thanks, John Hunter zope 2.7

Hello, I was not able to find the following images when I checked out the Zope Book sources: "Database Cache settings":img:23-1:Figures/dbcache.png "Viewing the pricelist method":img:9-1:Figures/9-1_bobsfeedbags.png The later was reported in http://mail.zope.org/pipermail/zdp/2004-April/004572.html but not yet fixed. I found this image at http://www.zopewiki.org/Figures/9-1_bobsfeedbags.png but Google did not found a hit for the dbcache.png image. Kind regards Andreas.

MailBoxer + Kerio
by Kyle Mott 10 Sep '04

10 Sep '04

Hi. I'm looking for some type of 'imap-to-zope-gateway' script. It should interface with MailBoxer [http://mjablonski.zope.de/MailBoxer/] I talked to the developer and he has heard rumors that these scripts exist. The standard 'smtp2zope.py' won't work because our MailServer (Kerio) won't allow us to pipe messages to a file. Does anyone know where I can find this, or another alternative? -Kyle Mott Directory of Operations, http://www.gadoz.com/

How to get Client IP adres with Zope behind Apachr
by Martin Koekenberg 10 Sep '04

10 Sep '04

Hello, I'm running Zope (2.7.0) behind Apache (2.0.50). I'm trying to get the client ip adres but I always get 127.0.0.1.... That's logical because Apache runs on the same server. How can I get the real users IP adres ? Thanks for your help...... Martin Koekenberg
