zope.org SVN Sandbox area created for contributors
by Gary Poster 18 Nov '04

18 Nov '04

SUMMARY: The Zope.org Subversion repository now has a sandbox area for collaboration by contributors. This area has no constraints for checkins except those listed in the contributors agreement, and is intended to promote experimentation and easy, quick sharing. Details and how-to are below. DETAILS: After the discussion of demo packages (http://mail.zope.org/pipermail/zope3-dev/2004-November/012739.html) and the constraints Jim mentioned for full-fledged inclusion in the Zope 3 repository (http://mail.zope.org/pipermail/zope3-dev/2004-November/012740.html) we have set up a SVN sandbox for easy collaboration on prototypes and other experimentation by Zope contributors: /repos/main/Sandbox. This lowers the bar for sharing significantly. The demos discussed in the thread above could be checked in without further modification, for instance. If they are modified to meet the standards for inclusion in the Zope 3 repository, development should move to the Zope 3 repository, or, for large or stand-alone efforts, to their own top-level project. The genesis of the sandbox came from Zope 3; however, developers using Zope 2 should not feel left out. Zope 2 development is also welcome to use the Sandbox area. Please see Jim's README in the top of the sandbox for his guidelines on use of the area: http://svn.zope.org/Sandbox/README.txt?rev=28473&view=auto HOW TO: If you are a contributor who wants to set up your corner of the sandbox, you'll want to make a directory there: svn mkdir -m "<checkin message>" svn+ssh://<zope.org user name>@svn.zope.org/repos/main/Sandbox/<your new sandbox name> Replace the <checkin message>, <zope.org user name>, and <your new sandbox name>. The sandbox name should have your name in it, the name of your project in it, or both. For instance, my command was svn mkdir -m "Making my corner of the sandbox" svn+ssh://poster@svn.zope.org/repos/main/Sandbox/poster Subversion should reply with "Committed revision <number>." Then check out your new sandbox: svn co svn+ssh://<your user name>@svn.zope.org/repos/main/Sandbox/<your new sandbox name> <local name on your machine for the checkout> For instance, my command was svn co svn+ssh://poster@svn.zope.org/repos/main/Sandbox/poster sandbox Further Subversion information is available in the zope.org Subversion wiki: http://dev.zope.org/Subversion/ Please use and enjoy!

I think this is not hte problem since Ape creates the database tables and its columns from scratch. You only must create the database. Anyway, after inspecting the tables I show a lot of blob columns. -----Mensaje original----- De: Andy Dustman [mailto:farcepest@gmail.com] Enviado el: jueves, 18 de noviembre de 2004 18:33 Para: jcc(a)umd.es Asunto: Re: [Zope-dev] Zope-2.7.3, Ape-1.0+ (from cvs) and mysql 4.0.20 raises UnpicklingError What column type are you using in MySQL?

Zope-2.7.3, Ape-1.0+ (from cvs) and mysql 4.0.20 raises UnpicklingError
by jcc＠umd.es 18 Nov '04

Hi all, I have spent over two days testing the Ape product, and all the time I become the error UnpicklingError, unpickling stack underflow . Here are my results: - Using a filesystem database works fine. - Since mysql creates the tables as myisam (non-transactional) per default after some failed tests I tweaked the code, so that the tables are created as InnoDB. - I have tried a fresh installed zope. - I have put some LOG statements into the code and here is the log: ------> 2004-11-18T18:00:58 INFO(0) ZODB conflict error at /sql/manage_addProduct/OFSP/addDTMLMethod (1 conflicts since startup at 2004-11-18T17:59:31) ------ 2004-11-18T18:00:59 INFO(0) apelib.zodb3.connection.setstate p = (dp1 S'class_name' p2 S'OFS.Folder.Folder' p3 sS'mapper_name' p4 S'folder' p5 s.(dp6 S'modtime' p7 L1100797193L sS'items' p8 (lp9 sS'id' p10 S'sql' p11 sS'security' p12 (lp13 (S'executable-owner' S'' S'' S'acl_users/jcoruna' tp14 a(S'local-role' S'Owner' S'' S'jcoruna' tp15 asS'remainder' p16 S"array('c')" p17 sS'properties' p18 (lp19 (S'title' p20 S'string' p21 S'' tp22 as. ------ 2004-11-18T18:00:59 INFO(0) zodb3.serializers.RemainingState.deserialize state = array('c') ------ 2004-11-18T18:00:59 ERROR(200) ZODB Couldn't load state for '5' Traceback (most recent call last): File "/usr/lib/zope/lib/python/Products/Ape/lib/apelib/zodb3/connection.py", line 360, in setstate event = osio.deserialize(oid, obj, classification, state) File "/usr/lib/zope/lib/python/Products/Ape/lib/apelib/core/io.py", line 160, in deserialize mapper.serializer.deserialize(event, state) File "/usr/lib/zope/lib/python/Products/Ape/lib/apelib/core/serializers.py", line 121, in deserialize s.deserialize(event, state) File "/usr/lib/zope/lib/python/Products/Ape/lib/apelib/zodb3/serializers.py", line 293, in deserialize s = u.load() UnpicklingError: unpickling stack underflow <------------ I think that the problem is that ape tries to unpickle the string "array('c')" and fails. Any clues? Sorry for the long post, but I think it's worth the length.

OK, is the test.py in the root an artifact of make instance, or has that bug been fixed completely very recently? It's still there in Zope 2.7.3, and it was still in Zope-trunk last week. -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/

webdav and excel read-only problem
by David King 16 Nov '04

16 Nov '04

I'm having the problem that others have already posted about [1][2]. Andreas Jung mentioned in a message from September 2004 that he had posted an explaination of the issues about two years ago. I've googled zope.org and manually searched every month in the archive at [3] and couldn't find that explaination. I've also searched through Microsoft's knowledgebase with no luck. Does anybody have a link to Andreas' message or a similar explaination of the problem?

connecting server code to the ZODB
by Tim Hicks 14 Nov '04

14 Nov '04

Hi, I'm trying to figure out how to adjust Nikolay Kim's smtpserver code <http://cvs.sourceforge.net/viewcvs.py/collective/smtpserver/> so that objects within the ZODB can affect the way that messages are received (i.e. veto messages based on certain criteria in the first instance). My problem is that I don't quite know how to get hold of the ZODB objects. As far as I can tell, Nikolay's smtpserver.SMTPServer.SMTPChannel.process_message method uses ZServer.PubCore.handle to make the connection, but I don't really understand how this all works. What I really want to be able to do from the server code is something like:: root = magic_that_gets_me_zodb_root() account_manager = root['Control_Panel']['AccountManager'] account_manager.checkAccepts(msg) I want calls like that to checkAccepts(msg) to be made a several points in the SMTP session - say after each of the SMTP commands RCPT, MAIL, DATA, etc. I only mention that in case there are implications for some transaction jiggery-pokery (although I don't expect any of the checkAccepts() type calls to need to write to the ZODB). Any pointers much appreciated. tim

Need a book recommendation(s) for newer patterns and component based design
by Ira 13 Nov '04

13 Nov '04

Hi. I am new to Python, Zope, and OOP. Can you please recommend a good book(s) on patterns, component architecture, and component-based design as referred to in the excerpt from the Zope X3.0 press release below? I am reading 'Design Patterns' by Gamma, et al, but it does not include interface patterns or perhaps other, newer patterns. Thanks, Ira ------ >From the Zope 3.0 Press Release: 'Richter said the rewrite was important as Zope 2 was built primarily using object-oriented techniques such as inheritance, while Zope X3 has taken advantage of newer patterns such as interfaces and component-based design. "The main goal was to clean up the architecture," said Richter. "In Zope 2 we only used the inheritance of objects to extend and build Zope, this only takes it so far because objects become unmanageable. Zope X3 has a new component architecture that allows you to extend objects and use interfaces." '
