No I don't think so. We are using ext2 but the problem could be the python interprenter as Andreas mentioned .. Gitte

Is it possible to import something to a zope server that i don't have telnet/shh access to? In other words, I can only access the web-based management interface. thanks in advance

YA newbie question (hey, I'm learning!)
by Kirk Strauser 17 Oct '01

17 Oct '01

Hello again, all. I am building a site that has many pages which are totally identical, with the exception of the database query that generates their contents. My idea was to create this hierarchy: Site/ Listings/ index_html (DTML doc) getContents (SQL method - a default that gets *all* possible content) SubListing1/ getContents (SQL method - specific for listing #1) SubListing2/ getContents (SQL method - specific for listing #2) ... That way, I could go to http://site.com/Listings/SubListing1 and see the standard index_html but with only the contents related to SubListing1. The problem I'm encountering is that my plan works well *as long as* there is no getContents method in the Listings/ directory. While this makes sense in a way, I was under the impression that SubListing1/getContents would take precedence. Is there a way to make it do so? I'd prefer to actually leave Listings/getContents in place as a fail-safe default value if at all possible. On a related note, I'd like to specify certain properties to be accessed in the index_html document (page title, one-line summary, etc.), and have those properties unique to each SubListing, with a set of defaults defined for everything in Listings. Is this possible? If so, where can I set those? Once again, anything I have defined in Listings seems to overwrite the values I define in SubListings, although I had expected it to be the other way around. Many thanks, -- Kirk Strauser

Problem rendering a document
by Steven Grimes 17 Oct '01

When trying to write a report which does some intense calculations I keep getting the following error in my browser: ! Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later. (107) bad stdout strlen (0) At the same time this shows up in the command window where I started an instance of Zope. I'm using Windows NT4 Server and IIS 4 with Zope 2.2.0 started in debug mode. The method I run uses ZODBCDA to connect to a database on a different server. Anyone have any idea what is going on and if there is anything I can do to fix this? 2001-10-17T16:23:54 ERROR(200) ZServer uncaptured python exception, closing channel <PCGIChannel at 19e3fc0> (socket.error:(10053, 'winsock error') [C:\Program Files\ATIAnywhere\ZServer\medusa\asynchat.py|initiate_send|211] [C:\Program Files\ATIAnywhere\ZServer\medusa\asyncore.py|send|274]) Thanks in Advance Steven Grimes Database Engineer sgrimes(a)atinucleus.com Accelerated Technology, Inc. 720 Oak Circle Drive East Mobile, AL 36609 www.acceleratedtechnology.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Over Ten Years of Providing Embedded Solutions ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is a list of live zope sites that (presumably) have reasonable amounts of traffic.

We hired a local evening programmer to build an internet brokerage weblication for us(his word). After a full year and a half we are all on line today and it is failing miserably. We called in a reputable company from the area and they tell us the problem is the platform. Our programmer insists that Zope can support our business and these are the kinks of a new use.

ZCatalogs addIndex requires JavaScript
by Kyler B. Laird 17 Oct '01

[vent ahead] It sure would be nice if the products that require JavaScript would be eliminated. At the very least, a warning would be appreciated. I just spent a couple hours trying to get started with ZCatalogs and I couldn't figure out why I couldn't add an index. It turns out to be some JavaScript kludge. Grrr.... --kyler

(That is, do you put code in a subdirectory of <zope>/lib/python/Product? If yes, just put your Python modules in the Extensions subdirectory of your Product directory, along with files defining your external methods. (Note that you can have more than one external method in a file.) Then, create an __init__.py file in the Extensions subdirectory of your Product. (I think you have to include __doc__ and __version__ strings in the __init__.py, but I'm not sure.) Finally, in __init__.py import all the files in the directory. (I think that makes Zope aware of them for purposes of updating.) I've found that with a setup like that, updating my product from the Control Panel updates all the Python modules and external methods in my product's Extensions directory. It even works with the automatic update feature you can turn on for your product in the Control Panel's item for your product.

RE: [Zope] Linux Zope <=> MSSQL
by sean.upton＠uniontrib.com 17 Oct '01

I think at some point there was a FreeTDS hack to the Sybase DA that would work with SQL Server 6.5, or something... Not sure if that would work for you or if it is currently maintained, and pretty sure M$ has broken TDS in recent incarnations of SQL server (embrace, extend, etc). Of course, I would think the following was interesting if I were in your situation: http://pyxsqmll.sourceforge.net/ I'm guessing you could hack the MySQLDA to sit on top of this. Of course, this is totally a guess, but it sounds doable. Disclaimer: I haven't done anything like this, haven't worked with MS stuff in a while, and just happened to remember seeing this.

It would be a big plus to run Zope on FreeBSD or (2nd choice) Linux. I started to look at SQL Relay, but got scared off by a discussion on its mailing list titled "Massive Memory Leaks".

Exactly. This would be a good start, imho. Right now I have "Use Database connection" and "Use Database connections".... :-P If they were grouped by product atleast this would be solved. Hmmm.. then you could have the "Acquire permission settings?" affect the whole product too.. /Magnus
