I think you are taking liberties with what I said. First, the server is not *THE* live webserver for Ford's corporate intranet, it is one among *many* and a rather minor one at that. If it were one of the main ones, there is no way they would let me run Zope one it (not an accepted "corporate standard"). In fact, the systems people here have been quite accommodating by even allowing me to run Zope. To answer your question, access to the machine *is* heavily restricted (I never indicated otherwise). That isn't the point. The point is that a (properly configured) named pipe *is* more secure than a port (even a localhost port) because the permissions can be controlled at the system level. So it seems reasonable (to me) for somebody to want to use a named pipe. In any case, I'm not looking to get into an argument about how well-reasoned our corporate security policies. I'm just trying to understand what the purported "more appropriate" alternatives are for PCGI. > Chris -- Mike

No module named GenericUserFolder
by Andreas Tille 03 Sep '03

03 Sep '03

Hi, I wanted to follow the hint about customizing the cache of an ZSQL method given in the Zope Book at chapter Relational Databases. When I try to press the Advanced tab of a ZSQL method I get: Error Type: ImportError Error Value: No module named GenericUserFolder Regarding to http://www.zope.org/Members/Zen/GenericUserFolder it seems that this is a remainder from some previous code which should not really belong to Zope 2.6.1 which I'm using. Or is there any other problem? Kind regards Andreas.

Charset HTTP header switched to UTF-8. Bug or feature ?
by Gilles Lenfant 03 Sep '03

03 Sep '03

Hi, There's a strange thing in a iso-8859-1 (natural) charset site Zope 2.6.1 powered... A form is summitted (POST) to a TTW python script. At the end of the script, after form validation ... <sample> return context.sometemplate(param1=value1, ...) </sample> The "sometemplate" is published with this HTTP header : Content-Type: text/html;charset=UTF-8 When nowhere in my scripts/templates, I stated to use that charset. You can imagine the ugly things that are displayed :-/ I found a workaround: forcing the HTTP header of the response... <sample> REQUEST.RESPONSE.setHeader('Content-Type', 'text/html; charset=iso-8859-1') return context.sometemplate(param1=value1, ...) </sample> Is this behavior a bug or a feature ? Note that with older versions of Zope (2.3.3) I didn't need to force the charset header like this. Thanks in advance --Gilles

Problem with product security and setDefaultAccess()
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 02 Sep '03

02 Sep '03

Hello, I've written a product that behaves much like a Database Adapter/Z SQL Method type combination, only it queries a web service, parses the XML, and returns the results. Most things seem to be working OK, only now I'm having trouble accessing the results through PythonScripts (i.e. restricted TTW code). (Thought the ZMI DTML works ok without complaining) The results are stored in a ResultSet class, which has as attribute a list of objects which are instances of the Result class (i.e. Records) ... This result class provides methods that I keep getting denied access to, no matter what I try. The ResultSet and Result classes do not subclass anything, they're real dumb, and non-persistent. I'm trying to access the gettypename() method, but I always get an access denied. I installed VerboseSecurity and it keep insisting that: The container has no security assertions. Access to 'gettypename' of (Products.Atlas.WFSResults.WFSResult instance at 0x8af92fc) denied. Which so far as I can tell isn't true, since the WFSResultSet DOES have a setDefaultAccess("allow") on it, which in this case should be perfectly safe, or at least good enough for testing. I've tried adding security assertions all over the place, including in the WFSResult class itself, on the method itself, etc ... without any change in the errors. I've tried declaring public, using specific permissions, etc ... I'm out of ideas ... help ? from xml.parsers.expat import ParserCreate from AccessControl import ClassSecurityInfo class WFSResultSet: ClassSecurityInfo().setDefaultAccess("allow") def __init__(self, getfeaturexml, typenames, typeinfo): class WFSResult: def __init__(self, typename, resultset): self.typename = typename self.resultset = resultset def gettypename(self): return self.typename # Define the expat parsing callback functions <snip> parser.Parse(getfeaturexml) resultsasinstances = [] for item in results: resultsasinstances.append( WFSResult( item[0], item[1] ) ) self.results = resultsasinstances def __getitem__(self, index): return self.results[index] Thanks, Jean-François Doyon Internet Service Development and Systems Support GeoAccess Division Canadian Center for Remote Sensing Natural Resources Canada http://atlas.gc.ca Phone: (613) 992-4902 Fax: (613) 947-2410

Who holds the domain zope.se?
by Dario Lopez-Kästen 02 Sep '03

02 Sep '03

Hello, [sorry for the crosspost] I was wondering if anyone here knew the person who holds the domain zope.se? I am curious about the plans for it... Thet site has a "No website here" in German, but the holder seems to be living in Stockholm: http://www.nic.se/domaner/domansok_result.shtml?domain=zope.se This question is actually related to the fact that I am wondering abut zope activities in Sweden. I'd like very much to have Zope promoted as a reliable platform "commercial-grade" application (i.e. one that is as accepted as Java and PHP solutions). I have no personal commercial interest in promoting zope (at least yet ;-) - my interest lies in being able to promote zope as an alternative to solutions like Oracle AS + Portal, uPortal, etc, etc. This will make my life much easier in the future... Thanks, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Zope slowdown publishing big tables
by Luton, Alex 02 Sep '03

02 Sep '03

Hi, I have recently written a few pages which either generate or contain large html tables. I started to notice some fairly substantial slowdown with tables over 100 or so rows. At a guess, I assume this is zope rendering all the <tr> and <td> tags looking for dtml, but it seems a bit slow even for that. We're running pretty substantial servers with plenty of memory, etc. I'd be interested in any good ways to improve the speed of these pages. The obvious answer would be caching, but I'd rather avoid the complications that entails if possible. I'm more interested in what Zope's really doing to slow itself down here.

REQUEST.unset('property') in DTML ?
by Jaroslav Lukesh 02 Sep '03

02 Sep '03

Hi all, I was read in archives about REQUEST.unset to unset property. But published patch is little older (1999) and my Zope 2.5.1 is totally different than that patch. Zope does not protest when I save DTML method with REQUEST.unset('property'), but when I access page, then Zope give me error that unknown keyword unset. Note that pythonic :) equivalent to unset <dtml-call "del REQUEST.other['property']"> could not be saved to server (error). It is possible to delete previously <dtml-call "REQUEST.set('property')"> in DTML ? Thanks a lot, J. Lukesh

Okey, I'll try to explain you. I have a combo box called "CboLocation" in my index_html page in the root folder of my proyect with some general information. I have a subfolder called "Add Data" where I have a page who add an entry to a database with some information. One of the fields that I need to add is the "Location" that I select in the first page, but when I try to load the "Add Data" page I got this error: Zope Error Zope has encountered an error while publishing this resource.

wiki-how to add comments to top of page
by Joshua Newman 02 Sep '03

02 Sep '03

Hi, On our wiki we have users entering comments with the comment box at the bottom of the page.. The wiki adds comments on the bottom after the last post. So the users have to scroll down to see the newest post. But with a long list this is annoying. Is there a way like squishdot, to locate the new posts to the top of the page? I haven't found the way to do it. Thanks. J

VHM mapping tab disappeared
by Michael LaPera 02 Sep '03

02 Sep '03

Hello All, I am having a very strange issue. I have been using Pound to redirect requests to several Zope application servers (behind a firewall) which, in turn, are talking to a ZEO server. I have been using Virtual Host Monster (VHM) to direct traffic from different domains to different Zope folders/CMF sites and it has (and is still) working beautifully. Well it's been about a couple months since I've added any new domains, using VHM mappings, so I went to VHM and the mappings tab is gone -- but VHM is still redirecting. I just can't figure out how to add more mappings... I am using Zope-2.6.1-linux2-x86 with the most notable Products being CMF 1.3.1, Plone 1.0.1 and DocFinderEverywhere 0.4.1. Please CC me on any replies since I am not subscribed to this list. Thank You, Michael LaPera <michael(a)lapera.com>
