problem with commits in SQLAlchemyDA
by Maric Michaud 27 Apr '10

27 Apr '10

Hi all, I wanted to use SQALchemyDA with a standalone Zope 2.11 (we only depends on CMFCore). i tried to get it up using easy_install, which is pretty straightforward, once removed the incompatible zope.component package needed in the dependencies. It ends up with the following installed packages (skipping zope 3 components) : zope.sqlalchemy-0.4-py2.4.egg z3c.sqlalchemy-1.3.10.1-py2.4.egg SQLAlchemy-0.5.5-py2.4.egg Products.SQLAlchemyDA-0.4.1-py2.4.egg At first glance, this works well, but the DA actually can't manage to commit any sql requests (I try only for insert in Mysql and postgres but I'm sure it's always true). This is quite an unexpectable behavior for a DA. I think the problem is related to this thread I found on tg-trunk newsgroup : http://www.mail-archive.com/turbogears-trunk@googlegroups.com/msg07302.html There is a misleading comment in the docstring of zope.sqlalchemy.datamanager.join_transaction speaking of a DirtyAfterFlush SessionExtension, which I never seen except in plone code. In the last I finally manage to make it work by monkey patching SQLAlchemyDA itself this way : try : from Products.SQLAlchemyDA import da from z3c.sqlalchemy import getSAWrapper, createSAWrapper if '0.4.1' in da.__file__ and not hasattr(da.SAWrapper, '_patched__wrapper_property') : da.SAWrapper._patched__wrapper_property = da.SAWrapper._wrapper def _always_invalidated_wrapper(self): """The property '_wrapper' patched by CFENet to correct what seems to be a bug in SQLAlchemyDA which prevents any commit.""" from zope.sqlalchemy.datamanager import STATUS_INVALIDATED if self.dsn: try: return getSAWrapper(self.util_id) except ValueError: return createSAWrapper( self.dsn, forZope=True, transactional=self.transactional, engine_options={'convert_unicode' : self.convert_unicode, 'encoding' : self.encoding}, extension_options={'initial_state': # the whole # point is here STATUS_INVALIDATED}, name=self.util_id) return None da.SAWrapper._wrapper = property(_always_invalidated_wrapper) except ImportError : pass Anyone has any insights about this problem, any comments on my solution, did it have been reported and corrected, or am I simply missing something ? -- _____________ Maric Michaud

We have a project where we are using Formulator under CMF 1.X + Zope 2.8. Unfortunately Formulator seems to horribly broken Zope 2.11.

strange database read conflict error
by Dragos Chirila 28 Aug '09

28 Aug '09

Hello everyone, I have a question regarding a database read conflict error. I would appreciate any thoughts on this issue. I am using Zope 2.8.9.1-final, Python 2.3.7 with a ZEO server and 4 clients for 6 months now. I have noticed that the event.log is filled with read conflict errors like the one below: 2009-08-28T10:29:26 INFO ZODB.Conflict database read conflict error (oid 0x09, class Products.Transience.Transience.Increaser) at /VirtualHostBase/http/metropotam.ro:80/metropotam/VirtualHostRoot/Opera/loc4769172835-Ateneul-Roman/ (21 conflicts, of which 0 were unresolved, since startup at Thu Aug 27 15:25:02 2009) This URL of the object is http://metropotam.ro/Opera/loc4769172835-Ateneul-Roman . We have around 2000 objects of the same type and this is *the only one* that generates read conflict errors. I have tried a few things: 1. Edit object and recatalog it 2. Rename it 3. Delete object, pack database, create a new object and then rename it to keep the URL alive 4. checked the data.fs and got no errors (fstest.py) None of the above solved the problem; I still get a lot of conflicts. Is there a way to fix this? I found it very strange that I get conflicts only for this object and for no other of the same type, even in the same folder... Thank you, Dragos Chirila

Zope and wxPython interface
by Lumir Jasiok 14 Aug '09

14 Aug '09

Hi, I need to write an application which will be based on MVC design and will have both web interface and desktop GUI based on wxPython. It is possible to write such an application as standard Zope app and use zope.interfaces package for defining wxPython GUI as other view (I hope that it's called view, I am not sure - I am new in Zope programming)? Or am I totally wrong? Best Regards Lumir Jasiok -- Lumír Jasiok VSB-TU Ostrava - Computer centre Tel: +420 59 732 3189 E-mail: lumir.jasiok(a)vsb.cz http://www.vsb.cz

It's strange that this recipe is still being developed since it isn't needed for Zope 2.12. I've CC'ed in a couple of the people currently working on it, hopefully they can comment? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
