Exploring non always repeating tracebacks in test case
by Marco Bizzarri 03 Jan '07

03 Jan '07

Hi all. I'm trying to explore the possible reasons behind some strange traceback which on some conditions (unknown to me at the moment) appears while running my ZopeTestCases. When I run all my tests, sometimes I get no error. Sometimes I get from 3 to 5 tracebacks, all related to the same part of the code. Here is one of those tracebacks. ERROR: testActIntegration.DeterminationTestCase.testProposal ---------------------------------------------------------------------- Traceback (most recent call last): File "testActIntegration.py", line 106, in testProposal draft.fromScratch(AUTHOR) File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Acts.py", line 1298, in fromScratch self.makeDocumentUsingData() File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Acts.py", line 1085, in makeDocumentUsingData 'application/pdf') File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Documents.py", line 676, in setBinaryFileType self.updateData(file, content_type) File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Documents.py", line 558, in updateData data, size = self._read_data(file) File "/var/local/zope27/base278/lib/python/OFS/Image.py", line 518, in _read_data get_transaction().commit(1) File "/var/local/zope27/base278/lib/python/ZODB/Transaction.py", line 241, in commit ncommitted += self._commit_objects(objects) File "/var/local/zope27/base278/lib/python/ZODB/Transaction.py", line 356, in _commit_objects jar.commit(o, self) File "/var/local/zope27/base278/lib/python/ZODB/Connection.py", line 452, in commit dump(state) File "/usr/lib/python2.3/copy_reg.py", line 69, in _reduce_ex raise TypeError, "can't pickle %s objects" % base.__name__ TypeError: can't pickle function objects Of course, there is a lot of my code here, so basically I'm not asking about the problem, but on how I could further explore the problem (aside from putting a conditional break in the code and run the tests until it is activated). Another (related) question is related to the following snippet, from OFS.Image: File "/var/local/zope27/base278/lib/python/OFS/Image.py", line 518, in _read_data get_transaction().commit(1) Here we have therefore a subtransaction committed. This worries me a lot, since my code deals, at the same time, with PostgreSQL database and ZCatalog. In the ZCatalog, the subtransactions where disabled since they were not compatible with PostgreSQL. I think there is a similar issue with subtransaction in Image... am I wrong?

The product I made isn't in the product management page
by Allen Huang 03 Jan '07

I'm using Zope 2.8.8 and I trying to make my own product. Whenever I make a product with errors in the python coding, I could see my product name registered in the product management page. But when I fix all the error, the product disappears; it not in the product management page or the add menu. What is the problem here? here is my coding __init__.py-------- ------------------- import helloModule def initialize(context): context.registerClass( helloModule.helloClass, permission="Add Hello Object", constructor=( helloModule.manage_addHelloForm, helloModule.manage_addHello ) ) helloModule.py-------- ------------------------ def manage_addHelloForm(self): " Form for adding a Hello Object " return """ <html> <head> <title></title> </head> <body> <form method="post" action="./manage_addHello"> <input type=text name=id> <input type=submit value="Add Hello"> </form> </body> </html> """ def manage_addHello(self): " Method for adding a Hello Object " newHello=helloClass(id) self._setObject(id, newHello) return self.manage_main(self, REQUEST) class helloClass: meta_type='Hello Object' def __init__(self, name='World'): self.name=name def saySomething(self): return "Hello, " + self.name def edit(self, name): self.name=name __________________________________________________ Do You Yahoo!?

thanks for repling Marco. I'm using a window version of zope and linux command 'zopectl fg' doesn't work. what is the forground command in windows? Is the "run in console" the same as forground?? ----- Original Message ---- From: Marco Bizzarri <marco.bizzarri(a)gmail.com> To: Allen Huang <swapp0(a)yahoo.com> Cc: Zope <zope(a)zope.org> Sent: Wednesday, January 3, 2007 11:48:59 AM Subject: Re: [Zope] The product I made isn't in the product management page Two suggestions: 1) run zope in foreground, so that you can see if Zope is complaining about your project; 2) make helloClass derive from OFS.SimpleItem.SimpleItem.

[zope 2.7-2.8] Howt to alow import module in Python script
by Mihamina Rakotomandimby 02 Jan '07

02 Jan '07

Hi, As far as I know, if I want to use/import a module (let's say urllib*) in a Python Script (the restricted ones), I have to use external methods and then use it in the Python script. I remember I saw in a zope related Mailing List (CPS, Plone, Zope...) I cant list somewhere the modules I want to be loadable from restricted Python script. Would you remind me the place I could do it please? Thank you. I mostly need urllib, ftplib, re, HTMLParser,...
