ParsedXML create from a Python script
by Brian Sullivan 17 Nov '05

17 Nov '05

I am trying to figure out how to create a ParsedXML object from a Python script and have it parse XML text that I have in string. I have managed to create the object with no content( or default content) but am not sure what to do to have my xml string parsed and contained. Does anybody have a sample of code that does this or can point to a resource with this information?

Does anybody us Komodo to debug Zope?
by Jerry Westrick 17 Nov '05

17 Nov '05

Hello List.... Since I already own komodo (For perl developement), I was wondering if you can use Komodo to debug zope. The only link I found was: http://www.zope.org/Members/andym/KomodoDebugging (dated 2003). Which didn't seam to offer much. Anybody out there using Komodo? Jerry

Passing Parameters to External Methods
by Asad Habib 17 Nov '05

17 Nov '05

Hello. I am trying to use the Python version of the PHP script written by Jason Rust called 'HTML_ToPDF.php'. I have represented this script using an External Method since it uses functions, such as open, which cannot be used in Zope Python scripts for security reasons. The python code for the script consists of a class definition and so I have had to create a python function which instantiates an object of this class. However, I am having toruble passing parameters to this function which are needed by the class constructor to instantiate an object of this class. Can parameters be passed to external methods? Whenever I try to pass parameters to function 'createHtmlToPdf', Zope returns an error stating that no such function exists. Other on the hand, if I pass no parameters this call is successful but the init function fails complaining that three parameters are expected. I have provided a snippet of my code below. Any help would be greatly appreciated. Thanks. - Asad def createHtmlToPdf(in_htmlFile, in_domain, in_pdfFile): return html2pdf(in_htmlFile, in_domain, in_pdfFile) # This is based on a php script (c) Jason Rust <jrust(a)rustyparts.com> # See that script for licensing # Convert an HTML file to a PDF file using html2ps and ps2pdf from tempfile import gettempdir, mkstemp import os import re from re import IGNORECASE, DOTALL from copy import copy class html2pdf: def __init__(self, in_htmlFile, in_domain, in_pdfFile = None): """Constructor in_htmlFile The full path to the html file to convert in_domain The default domain name for images that have a relative path in_pdfFile (optional) The full path to the pdf file to output. If not given then we create a temporary name. """

probably a simple answer...
by Kate Legere 17 Nov '05

17 Nov '05

So this probably has a simple answer but if someone could direct me it would save lots of time ... I have a python script that gets called from a dtml method and returns the information requested from a mySql database and opens it as an excel file. I'd like it also to save the file (it can safely overwrite the existing file) ... how do I do this? ---the python script has request = container.REQUEST RESPONSE = request.RESPONSE table_example = <-- html table formatting tags and python code to get the info from the database --> RESPONSE.setHeader("Content-type","application/vnd.ms-excel") RESPONSE.setHeader("Content-disposition","attachment;filename=statsSpreadshe et.xls") return table_example ----------------- Kate

question about Zope capabilities
by Rich Robinson 17 Nov '05

17 Nov '05

Hi, I'm brand new on this list and writing to get a bit of insight here. We had someone design a web site using Zope, and very pleased with it. That person is no longer with us and I'm not at all a savvy back-end person, let alone Zope-savvy. At this point, the site is great for managing content via the database. However, as far as I can see pretty much all the content needs to fit into templates, with the result that there appears to be little room for setting up a more free-form looking page that can incorporate graphics in a freer, more visual way. Sure, we can add images and any HTML we like, but they are confined to the areas designated by the templates. In other words, the site tends to "look like" a database-driven website - not unpleasing by any means, but I'm wondering if Zope lends itself to more "creative" looking pages that departs from the templated look. At zope.org there is a list of sites using Zope that I'll have a look at, but I'd be appreciative of any feedback. We are thinking of hiring someone with more graphics than back-end experience and I'd like to hear if anyone thinks Zope is adaptable to give someone plenty of creative expression. Thanks! Rich

Apache-pound-zeo-zope instances. Bad gateway and dual cpus related issues
by Christophe Gravier 17 Nov '05

17 Nov '05

Hi, I did not find any "architecture related" mailing list, so I deceided topost on the general list. I hope this is OK. I am struggling with my new zeo/zope architecture for some days now. I come to the conclusion that I should ask for help. I currently single cpu machine hosting zope + apache. I am trying to migrate to the architecture: machine A : Apache+pound machine B : 1 zeo + 1 zope machine C : 2 zope machine D : 2 zope all dual core, debian etch testing, Zope is 2.8.1-final and python 2.3.5. 1) Apache (machine A) In /etc/apache2/apache2.conf I inserted the rewrite rule: [...] NameVirtualHost 161.3.50.16 <VirtualHost 161.3.50.16> ServerName ist-guizay.univ-st-etienne.fr DocumentRoot /var/www/ RewriteEngine On RewriteRule ^/(.*) http://161.3.50.16:81/VirtualHostBase/http/ist-guizay.univ-st-etienne.fr:80… [P] </VirtualHost> [...] That is to say that ist-guizay.univ-st-etienne.fr is machine A ... I want to pass to my pound (listening on the same machine, port 81), all request on 80 port of ist-guizay.univ-st-etienne.fr 2) Pound (machine A) In /etc/pound/pound.cfg, I have: [...] ListenHTTP *,81 UrlGroup ".*" BackEnd ip_machine_B,8080,1 BackEnd ip_machine_C,8080,2 BackEnd ip_machine_D,8080,2 EndGroup [...] The architecture is all hosted in the same service (inside an university, no external firewalls except the one on the machine that are filtering zeo/zope/pound/apache ports). I can do : http://machineB.mondomain.com:8080 http://machineC.mondomain.com:8080 http://machineD.mondomain.com:8080 All give me the welcome Zope installation page, as well as http://machineA.mondomain.com:81. (pound conf is ok) But I cannot go any further in my installation. There 2 things that troubles my understanding: A) RewriteRule: http://machineA.mondomain.com as well as http://machineA.mondomain.com/Portail (where /Portail is the path to plone site in fact), both replies: "Bad Gateway The proxy server received an invalid response from an upstream server." I shall have done some mistakes in apache2.conf on the rewriterule: RewriteRule ^/(.*) http://161.3.50.16:81/VirtualHostBase/http/ist-guizay.univ-st-etienne.fr:80… [P] but obviously I don't see it. The current production for 2 years does work (one single cpu with both apache and zope instance) with the same kind of RewriteRule mechanism. B) About running zope on dual core cpus: Not as critical but I missed something here too. I read (http://mail.zope.org/pipermail/zope/1999-December/100589.html) that python core got some lock policies in single thread mode, but I expected to associate one instance per cpu to solve it out. That is the reason why I configured 2 instances per machine (they are dual core ...). Nevertheless, If I log into machine B (running two zope instances), making tail -f ./instances/instance1/log/Z2.log and in another terminal, for the same machine: tail -f ./instances/instance2/log/Z2.log Then, I configure pound to redirect all requests on machine B and finally hit http://machineB:81 a lots, all requests goes to instance1 (first launched). I would expect the system to make the balancing (if one cpu is used by a thread instance1, instance2 can still response with cpu 2 ...) Obviously this is not the case, why ? I solve it by making instances listen on different ports so that pound got now 2 differents entries for one host (one entry per instance). Sorry for the long post, but these are all things needed to be explained to let you understand my problem.

Installing Zope on Ubuntu Breezy
by Weiers Coetser 17 Nov '05

17 Nov '05

Hi I wonder if anybody could tell me what I am doing wrong. I installed zope 2.8, and plone 2.1 via synaptic. I also installed plone-site via synaptic. (When I installed this I was promted for a username and password) Now when I access: http://localhost:8081, I get a quickstart screen. When I click on the link to the management interface (http://localhost:8081/manage) I am promted for user name and password. It does not accept the username and password that I typed when setting up plone-site. I've been googling, and at one place there was an explanation that zope sets up an inituser file with a username and password. I found such a file under /var/lib/zope2.8/instance/plone-site/ with the following information in it: admin:{SHA}JPpU/BsXGIcv7LQrwgMiOS25PB4= I've tried to use this in various ways: username: admin password: {SHA}JPpU/BsXGIcv7LQrwgMiOS25PB4= or username: {SHA}JPpU password: BsXGIcv7LQrwgMiOS25PB4= That did not work. I tried to create a new inituser account using the following command weiers@weiers:/usr/lib/zope2.8/bin$ sudo python zpasswd.py inituser and then got the following feedback: The programme asked me for a username and a password, to repeat the password. I also selected SHA as a mode of encrypting the password, and left the domain restrictions blank. Unfortunately when I try to connect to (http://localhost:8081/manage) I still get the same problem. It won't accept my password. I tried to look for other inituser files on my computer, but I do not see any. ----> I am really stuck. I don't know how to get plone or zope to work on my computer. Please help. If you help me, I promise that I will write the details into a wiki somewhere. Thanks Weiers

ZopeTestCase.Functional and sessions?
by Paul Winkler 16 Nov '05

16 Nov '05

Hi, I've been using CMFTestCase and ZopeTestCase for integration tests and mostly finding it a pretty nice system to work with - I can finally test all the glue code in my skin scripts, which has always been a big blind spot in my tests. But one snag I've run into: ZopeTestCase.utils.setupCoreSessions() works fine with regular ZopeTestCase and CMFTestCase tests; but if I create a test derived from ZopeTestCase.Functional, when I call self.publish() the thread that handles the publishing (it is another thread, right?) has its own app.REQUEST which doesn't contain a SESSION object. The workaround is obvious: 1) Any script that uses sessions should only be tested with other techniques than publish(). 2) If you really want to test something about that script with publish(), the script should be coded so that it works around the possible lack of REQUEST.SESSION. But it would be nice if I didn't have to enforce that. #2 means that when I call publish() I am testing a code path that never actually comes up in production, so that doesn't seem like much of a real integration test. Am I missing something? -- Paul Winkler http://www.slinkp.com
