ZODB & Zope 2.8 ZRDB/TM : "raise" + "except: pass"
by Pelletier Vincent 09 Feb '08

09 Feb '08

Hi. I triggered a bad behaviour in Zope 2.8 Transaction class: try: <do something> <commit> <- raises conflict error from ZODB's tpc_vote except: <cleanup> raise Here, <cleanup> uses a transaction-registered connection which is not used before, hence not registered to transaction manager. So that connection tries to register by calling Shared/DC/ZRDB/TM.py:TP._register. Which ends up calling "join" on a status = Status.COMMITFAILED transaction, which raises TransactionFailedError in _prior_operation_failed. Note that before raising, Transaction.register did adapter.objects.append(obj) The raise is caught in TM._register, which prevents it from setting self._registered = 1 A second use of the connection will cause TM to call Transaction.register again because if not self._registered: evaluates to True. But this time, Transaction.register will not raise, since if adapter is None: now evaluates to False. As it does not raise, TM will set self._registered = 1 So now there is a connection which is set as registered, but which will not be commited nor aborted by transaction. Worse, as TM checks self._registered before registering to transaction, the connection will never be registered again. -- Vincent Pelletier

Character display issues upgrading 2.8.8 to 2.9.8
by John Schinnerer 09 Feb '08

09 Feb '08

Aloha, I am in the process of moving from zope 2.8.8 to zope 2.9.8 (running on debian 4.0). I am transferring individual zope sites from 2.8.8 instance to 2.9.8 instance via export/import. So far everything is fine except... I have some content in StructuredDocument objects that includes text with some accented French characters, and some of the curly quotes (the 6--9 quotes) and "real" apostrophes and that sort of thing. They are not displaying correctly in the 2.9.8 zope - they show up as whatever symbol the browser uses to say "oops, can't display this correctly." Both zopes are running on my dev system and I'm looking with all the same browsers so it seems it must be something to do with zope handling the characters (or not). The zope.conf settings for default-zpublisher-encoding are left at the default (iso-8859-15) in both instances, if that is relevant. I've never had any problem like this before, such as in previous upgrades of 2.7.x to 2.8.x. I don't even know where to look, aside from the zope.conf setting above which is the same in both cases. Any ideas why this is happening? Any help appreciated! thanks, John S. -- John Schinnerer, MA WSD ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net

I have checked everything. Even tried connecting to a different Zope instance. Same problem. I just built out this new server. It says the authentication has failed. I am going in with the IP address and correct port addresses (8021, etc) TIA, Trevor On Feb 7, 2008 9:52 AM, Andreas Jung <lists(a)zopyx.com> wrote: > > > --On 7.

undo error
by Webmaster 07 Feb '08

Hi, I am getting an error when trying to undo the deletion of a form created with PloneFormGen. One of the users on the site created a second copy of the form which received some submissions in error prior to its deletion and I was hoping to undo the delete to get the saved data. Is it possible to determine which subsequent changes need to be undone prior to being able to undo the delete. Here is the error: This site encountered an error trying to fulfill your request. The errors were: Error Type MultipleUndoErrors Error Value Undo error 0x047eae: Undo error 0x047eae: Some data were modified by a later transaction Undo error 0x047efa: Undo error 0x047efa: Some data were modified by a later transaction Undo error 0x047ed9: Undo error 0x047ed9: Some data were modified by a later transaction Undo error 0x046702: Undo error 0x046702: Some data were modified by a later transaction Undo error 0x047f01: Undo error 0x047f01: Some data were modified by a later transaction Undo error 0x046c19: Undo error 0x046c19: Some data were modified by a later transaction Undo error 0x026c2f: Undo error 0x026c2f: Some data were modified by a later transaction Thanks in advance for any assistance.

No, it didn´t work. So I decided to screw around and try an url instead of the ip. It liked that. Mabye it didn´t clear pound´s checks, or possibly a problem with vhm.

Zope lists in google
by Josef Meile 07 Feb '08

07 Feb '08

Hi, Today I noticed that google doesn't find anything when giving "site:mail.zope.org" anymore. It worked before :-( Moreover, when you get the robots.txt from the list: http://mail.zope.org/robots.txt You will see: User-agent: * Disallow: / So, is it intended that the zope list aren't indexed by the search bots or is this an error? Best regards Josef

ANNOUNCE: zif.sedna-0.9beta
by Jim Washington 07 Feb '08

07 Feb '08

The Zif Collective is proud to announce yet another confusing option for your applications. Sedna is a "native" XML database, open source, licensed under Apache 2.0 license. See http://modis.ispras.ru/sedna/ for features and download. zif.sedna communicates with Sedna. zif.sedna provides a dbapi-like interface (connections and cursors). zif.sedna provides a zope(3) database adapter and connection pooling (thanks to some code from sqlalchemy). It is provisionally thread-safe. zif.sedna is pure python. XQuery can be cool. zif.sedna is now available at the cheese shop. http://pypi.python.org/pypi/ The readme came out a bit funny there. I know there were some < and > in the document when I wrote it, so you will have to use your imagination a bit to read the blurb. Or easy_install it and read the docs as they were intended. -Jim Washington
