Uncaptured python exception
by Jon Emmons 31 May '07

31 May '07

I am using zope 2.9, python 3.4. when I have a bug in my python I get "Uncaptured Python Exception" coming from zope. This is a nightmare. I have spent hours trying to trace down the simplest typos that would have been instantly reported in any other development environment. How do I get zope to "Capture" these exceptions? I just want to know what line the error occurred in! Anything at all would be helpful! Do I need a different version of zope or python? Perhaps a python module? Jon

Function reindexObject()

Hi, I have made some python scripts to export data of some zope2.7 products in text file, and I have made some scripts to import theses data to rebuild products in zope2.9. Theses scripts run very well. But my problem is that all product that is rebuilt are in /SITES/plone_mySite/ I want rebuil all product in zope2.9 in the same directory as zope 2.7. I have the same structure for zope 2.7 and zope 2.9. My Import script ------------------------------------------------------------------------- id = self.generateUniqueId('J_product') self.invokeFactory('J_product', id) mct = getattr(self, id) mct.setTitle(row[1]) mct.setJ_product_descriptif(row[2]) mct.setJ_product_web(row[3]) ## add images ## im = recup_image(mesimages,compteur,"") if im != 'no_image': mct.setJ_product_image(im) self.portal_workflow.doActionFor(mct,"publish", comment="") self.reindexObject() ---------------------------------------------------------------------------- Thanks Julian

Redirection problem
by Ken Ara 28 May '07

28 May '07

We have a filesystem product with an edit method that allows users to change some properties. At the end, the user is redirected to the page from which they came. Our setup has Squid in front on port 80, with Pound on port 81 load-balancing to 3 ZEO clients. No matter how we define the redirect URL - even when we hardcoded it explicitly with ':80' for test purposes - the redirection is always to port 81. What is going on? Thanks!

this snippet behaves differently on windows and linux: http://zope.pastey.net/42188-1gbl I would be thankful of any clues to why. in linux it copies a gif picture off the filesystem and into the zodb. In windows. the object gets created but no gif is present.also no errors in the log -- -- Einar Næss Jensen http://einarblog.homemade.no/einarblog http://www.homemade.no tlf: +47 90990249 (\__/) (='.'=)This is Bunny.

Unauthorized: You are not allowed to access 'manage_page_header' in this context
by Yuri 25 May '07

I've an application in Zope. A user see this message when he try to submit a form. I've tried myself with his account and I had no error. I'm using OpenFlow, if it matters. The user is never sent to the openflow instance, so I don't understand how he tries to request this url. Can be a browser problem? The user is sent to management screen with no apparent reason: Time 2007/05/25 10:12:05.769 GMT+2 User Name (User Id) ww (ww) Request URL http://myserver.com:8080/xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/pa… Exception Type Unauthorized Exception Value You are not allowed to access 'manage_page_header' in this context Traceback (innermost last): * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 306, in __call__ * Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec * Module Products.PageTemplates.PageTemplateFile, line 106, in _exec * Module Products.PageTemplates.PageTemplate, line 96, in pt_render *<PageTemplateFile at /xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/index_html used for /xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/paper>* * Module TAL.TALInterpreter, line 190, in __call__ * Module TAL.TALInterpreter, line 234, in interpret * Module TAL.TALInterpreter, line 569, in do_insertStructure_tal * Module Products.PageTemplates.TALES, line 221, in evaluate *URL: index_html* *Line 1, Column 0* *Expression: standard:'here/manage_page_header'* *Names:* {'container': <instance instance at b0556230>, 'context': <RendicontiFolder instance at b0556b60>, 'default': <Products.PageTemplates.TALES.Default instance at 0xb74e8c8c>, 'here': <RendicontiFolder instance at b0556b60>, 'loop': <SafeMapping instance at 9d2d1b0>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 0xb744604c>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at 9d2d1b0>, 'request': <HTTPRequest, URL=http://myserver.com:8080/xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/paper/index_html>, 'root': <Application instance at b59f72f0>, 'template': <PageTemplateFile at /xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/index_html used for /xxx/yyy/WorkFlow/ProcessInstances/1180080540.75/paper>, 'traverse_subpath': [], 'user': bersani} * Module Products.PageTemplates.Expressions, line 172, in __call__ * Module Products.PageTemplates.Expressions, line 160, in _eval * Module Products.PageTemplates.Expressions, line 116, in _eval __traceback_info__: here * Module Products.PageTemplates.Expressions, line 311, in restrictedTraverse __traceback_info__: {'path': ['manage_page_header'], 'TraversalRequestNameStack': []} Unauthorized: You are not allowed to access 'manage_page_header' in this context

Zope 2, local python script security
by David H 24 May '07

24 May '07

Hi Zope list, I have a (zope 2.8.8-final) folder that gives users with the role "Authenticated" the following Permissions: ------------------------------- . access contents . view - note: no webDav or FTP access is allowed ------------------------------- Playing around with wget and curl I find I can (with proper authentication) download the "published" but not raw source of zpt and python files available in the folder. So, for example, the script "\folder\pyDate" returns '2007/05/23' not its source, e.g. # module: pyDate from DateTime import DateTime return DateTime().Date() This is the behavior I want - as we have a requirement to keep source secure. I realize that source in Zope-Instance/Extensions is the most secure but I'm interested in local script security. Thanks, David

help with detecting mime_type
by Alan 24 May '07

24 May '07

Dears, In my external method I can get mime_type = file.headers.headers[1].split()[1] and then my code proceed based on which mime type was identified for the file uploaded. What happens now is that a user uploading a tgz file from a Windows platform and then my code did not identify it as a application/x-gzip-compressed or similar (it gets application/octet-stream). As far as I understood from this case, such mime type info is passed by user's system (where Windows usually is not aware of tar.gz, tgz etc format) rather than being set by zope server. So since I was not aware of that, my question is: does anyone know a better and reliable way of identifying a file mime type (or a file format) independent from which platform/browser it is submitted? I realise I can use a conditional for checking extension file name in addition to mime type detection. But I would go for that only if I cannot find anything fairer. Many thanks in advance.

unicode, zmi, utf-8, management_page_charset and default-zpublisher-encoding
by Joerg Baach 23 May '07

23 May '07

Hi *, I spent hours now reading documentation, blogs and mails, and still did not get my head around the whole unicode issue. This is what I would like to do: 1. Have content and forms displayed using zpts, encoded in utf-8. 2. Get the data back into zope as unicode. 3. Store unicode in properties of objects, e.g. folders. 4. Edit those properties in the ZMI. 5. Search them in the catalog. My findings so far I have documented in http://www.baach.de/content/unicode basically using 1. setHeader('Content-Type','text/html;; charset=utf-8') 2. marking form fields (firstname:ustring:utf8) 2. using ustrings as properties. Works fine, but - what do I do about the title property of objects, e.g. folder? Its seems that I can't change them to anything, because once deleted I can't replace them by ustrings. I found that there is default-zpublisher-encoding and management_page_charset, but these make ustring etc. vanish from the zmi. So, should I use the management_page_charset and default-zpublisher-encoding instead of ustrings for storing data? I can't find anything that explains those six components (setHeader, form-field-ustring:utf8, ustrings, management_page_charset, default-zpublisher-encoding, title property) together, but would really like to understand how its working, preferably accross Zope versions. I am very willing to write a tutorial on it, so I am happy about any pointers. I am currently testing with Zope 2.8.5-final + python 2.4.4, and im the process of testing with the newest 2.10.x Cheers, Joerg
