MySQLDA on BSD
by Ed Colmar 11 Apr '02

11 Apr '02

Hey all. I'm assisting with a BSD server that is attempting to get zope/MySQLDA going. Now, I know very little about BSD, and I don't have root. So, I'm just trying to get some information to pass on to the admin. Basically, zope and zope-MySQLDA were both installed from the BSD ports tree. Zope is running fine, and the ZMysqlda seems to be installed correctly. However the _mysql.so module was not in the right place, so I had him move it into the zope python path. Now, We're getting init failed on this module. Any ideas on this? Should we be building this from the source, or is there an easy solution using this existing file? Thanks! -ed-

Searching: Zcatalog, what else?
by Paul Winkler 11 Apr '02

11 Apr '02

Hi all, re. search engines in zope: I know there's Zcatalog, but I'm curious what my other options are for implementing searches. Simply finding a string in the body of a document would be great. For example, How would you do text search if your data is in an SQL database? Maintain a separate text index and update it every so often? You can tell I'm no dba. :) -- Paul Winkler home: http://www.slinkp.com "Muppet Labs, where the future is made - today!"

Zope crashing - updating Python 2.1.3
by Sion Morris 11 Apr '02

11 Apr '02

Hi, For a while Zope has been crashing frequently. I have attempted to solve the crashing by following the suggestions offered by Matthew Kromer on ZopeNewbies at http://www.zopenewbies.net/1012338535/index_html (Run single threaded, updating ZMySQLDA, change Script_magic constant, set environment variable ZOPE_SECURITY_POLICY, applying a patch, updating Zope to 2.5.1b1.) None of the suggestions made a difference :-( On Zope newbies today I saw this: "While the most recent release of Python is 2.2, there are a couple of bugs that have come up since 2.1.2 was released, in particular one bug that caused Zope to crash." Hooray... But the binary distribution of Zope 2.5.1b1, which I have installed, comes with Python 2.1.2. How do I update this Python to 2.1.3? Thanks in advance for any help, Sion

SSL
by D.Rick Anderson 11 Apr '02

11 Apr '02

What is the best method for implementing SSL for Zope on RedHat 7.1? I've tried the Apache front-end thing and it works for our local network but the web server is behind a firewall and something about portforwarding keeps it from working through the firewall. Isn't there some product that you can simply install into Zope that gives you SSL capability? I looked into MCrypto but it wouldn't compile correctly on this box. TIA Rick

Zope Tutorial Problems
by scollyer＠netspinner.co.uk 11 Apr '02

11 Apr '02

I'm having problems with the Zope Tutorial in Zope 2.5.0 binary distribution under Linux (kernel 2.4.10, SuSe 7.3 distro). a) I'm running Zope via ZServer as a non-root user, and I've added the tutorial to the Examples folder via the "Select Type to Add" menu. This seems to have worked fine, but when I select lesson 1, I get a long red message, telling me that "Zope cannot find the tutorial examples ..." b) I've created a new folder under the Zope Tutorial folder for the "Elvis Lives" site, and I created the DTML doc home.html by following the instructions in the tutorial. However, when I come to view it, I get a Zope Error like this: Error Type: KeyError Error Value: header.gif and a Python traceback. This looks as if Zope is failing to find header.gif, which may be related to the first problem. Anyone know what's going on here ? I have chmod'ed the whole of the Zope installation tree to a+w prior to running the start script, so I'm assuming it's not a perms problem. Steve Collyer

zope canon?
by zopedan 11 Apr '02

11 Apr '02

Is there any zope cannonical collection of whats useful/used in zope development, and what is not? I have a product I'm thiking of working on and I was looking at Zpatterns and thought, "Hey this sounds neat". Then I Thought "This doesn't look like its been updated in a few months, and the zope book only briefly mentions it's existance, does this mean I should think about using it, or that it's been enveloped by another project/product I should use instead, or that It's useless and dead?" Now I am suffering from i-bet-everyone-knows-the-answer-but-me-itis. "Does the whole zope community either no this is a dead end or that it's 'like the ONLY' starting point for a project like mine". Why should I re-invent the wheel when someone else has done the work for me? But at the moment I can't seem to find a way to tell square wheels from round ones. I know there is not only one way to do something in zope, but there are bad ways and better ways. Instead of asking specifically about Zpatterns I'll ask about products in general, how (without simply knowing before hand and working for d.c) do I know what is a good or bad starting place for a project. -Dan Narkiewicz
