(from the hip without much thought) -- mysqlUserFolder could be adapted easily to postgres since the interface is SQL and the differences there are (mostly) minor.

xml-rpc question
by Ben Avery 29 Oct '02

29 Oct '02

hi, I'm using Zope (2.6.0, Pyth 2.1.3, Solaris 2.7) as an XML-RPC server, and need to use the XML-RPC boolean datatype. I have a test python script, which accepts a single-struct (dictionary) parameter, checks a boolean value passed to it and responds with another boolean value, but I'm having problems with importing permissions. my script, booltest: ##parameters:=param from xmlrpclib import True, False if param['dead'] == True: alive = False else: alive = True return {'name': param['name'], 'alive': alive} when I call the method from a standalone python script, testbool.py: #!/usr/local/bin/python s=xmlrpclib.Server("http://www.myzopeserver.com") p1 = {'name': 'ben', 'dead': xmlrpclib.False} res = s.test.testbool(p1) print str(res) I get a Zope error (bottom of stacktrace returned): ImportError: import of "True" from "xmlrpclib" is unauthorized. You are not allowed to access True in this context for the security settings of the folder that booltest lives, I have set the user to have permissions on: access contents information import/export objects query view is this a problem with security settings on the object or container, or something else? can anyone help?

apache - virtual hosts - zope
by Josef Kandlhofer 29 Oct '02

29 Oct '02

Hi, we use Zope 2.3.3 and cant upgrade. This version doesnt support virtual host monster!?! We want to use apache on port 80 to connect to zope-http-server. On the apache we use several virtual hosts (a mixture of name-based and ip-based virtual hosts), which refer to different subfolders of zope. I wanted to use mod_rewrite, but therefor i need virtual host monsters?!? What and how can i use instead? (mod_proxy - virtual hosts - site access perhaps??)

zclass propertysheets
by Danny Morgan 29 Oct '02

29 Oct '02

for some reason, I can get some propertysheet information, but not others: with 'history' being a property sheet of a ZClass, These work: return(context.propertysheets.history.propertyMap()) return(context.propertysheets.history.getPropertyType('recent')) But not this: return(context.propertysheets.history.getProperty('recent')) Any clues will be appreciated Danny

You might look at mysqlUserFolder. I've not used it (yet) but will with my next project. And, yes, it is probably overkill for what you want. If you want something very simple, you can always roll your own.

How can I access an MS Access database through zope? I didn't find a db adapter that would allow me to do this. Did I overlook something? Thanks, Mark

RE: [Zope] Problem with ZMI left frame ...

Oh I forgot to mention, the problem is the "Path" section of my root objects isn't getting used ... It tries /p_/pl instead of /site/p_/pl, as it should ... J.F. -----Original Message----- From: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca [mailto:Jean-Francois.Doyon@CCRS.NRCan.gc.ca] Sent: Monday, October 28, 2002 1:10 PM To: zope(a)zope.org Subject: [Zope] Problem with ZMI left frame ... Hello, On friday, I swtich my Zope setup to use Apache+mod_proxy+ZServer instead of Squid+Apache+FastCGI ... And all this went very well, and seems to work better than what I had before ... Just one slightly odd behavior though ... In the ZMI, the left frame, with the expandable tree, the "+" signs appear as broken images !! I've tried quickly to figure out where the logic is that implements this, but can't find it ... I have SiteRoot object, and everything else on the site and ZMI works just fine ... just not THAT one ... Could someone point me in the right direction ? Thanks ...

29 Oct '02

I am getting an intermittent error from the session_data_manager object that gives me the following information: Error Type: KeyError Error Value: duplicate key 24438444A0h9Emyt1QA The traceback is below. I have a Python Script named standard_security_header that is checking session data upon entry into certain pages. The line in that script that is referenced in the traceback is: session = request.SESSION Any idea as to why this duplicate key error is happening?

Webdav and cookie based authentication: exUserFolder compared to cookie crumbler
by Heimo Laukkanen 29 Oct '02

29 Oct '02

Hi, I've been setting up my new development enviroment and have had some problems with exUserFolder - in cases where the service has used cookies based authentication. I've mounted my zope-service with davfs and accessed it well, but problems have risen when I have needed to write through webdav - since the authentication has not worked. However when I've used cookie crumbler to provide the cookie based authentication - everything has worked fine. Has anyone else seen and seen this to happen -- and is there something that should / could be done? -huima

Default Number of Python Threads
by Bert Vanderbauwhede 29 Oct '02

29 Oct '02

Hi, I have Zope (version 2.5) running on three machines, each one running Red Hat Linux 7.2. By default, Zope uses 7 Python threads on two of those machines, but 8 on the other (a dual-processor machine). Is this a problem?
