Re: [Zope-dev] Possible ZCatalog Bug
Does this work?
(it does for me)
If not, does this?
If so, what kind of index is 'date'?

Regarding the code downloads: I think code for the CMS stuff will be publicly available rather soon.

For ZQuest and Proiektor we might not offer a PUBLIC download before the code is reasonably cleaned up. but for "hard-core" developers who can live with "half-baked" stuff as you put it: Stephan can give you the code.

[Zope-dev] ZCatalog FieldIndex Bug
Hi, Correct me if I'm wrong, but if I query a field index with an empty string, I expect to get returned all catalogued objects where that attribute's value _is_ the empty string. Anyway, this happens most of the time and I wish it happened all the time. Basically, the only situation where this _doesn't_ happen is when _none_ of the objects catalogued in the field index have a value of the empty string, which seems really bug and nasty to me ;-) Well, the attached .zexp will demonstrate the problem nicely. Import it and 'Test' the 'dotest' python script. ..then read the source. You'll also see my gripe about the hard coded redirect in manage_catalogReindex, which prevents you automatically re-indexing catalogs unless you use the hack I did. Right, I'm off to the collector :-) cheers, Chris fieldindexTest.zexp

API Documentation, a Demo, Feature List and so on are available on the site. 2. Proiektor - Proiektor is a groupware and project management system developed by iuveno. It is based on DBObjects and implements a nice set of features with some unique design ideas. But see yourself... 3. ZQuest - ZQuest was originally written for a university as testing tool and is now also developed by iuveno AG. It has a good set of features, especially for scientific questions. ZQuest uses DBObjects of course. If you are interested, click on the link above ... 4. CMS - Our Content Management System is coming soon with a true user-friendly management interface...

Re: [Zope-dev] MySQL-python-0.3.5 with ZMySQLDAMike
Mike, Is your Zope one of the standard installs or did you build it yourself? If it's one of the standard installs then it was built with Python 1.5.2. This means that your build of _mysql.pyd won't work with Zope as it was built with Python2.0. You will need to get Python 1.5.2 and rebuild _mysql.pyd. At least that's my take on it.

[Zope-dev] Trouble with ZODB when switching between Zope-releases with Python 1.5 and Python2.0
hi out there, I recently tried Zope-2.3.1b3 with Python 2.0 and it worked so far ... except some of the known issues at compile time .. I had trouble with a few products including ParsedXML so I switched back to Python 1.5.2 and updated to Zope-2.3.1 I did not replace my Data.fs. Everything works fine .. except when i want to browse one of my test-directories where I have many Instances of different Products I get this Error: --- ZopeERROR Error Type: UnpicklingError Error Value: invalid load key, 'X'. --- Traceback (innermost last): File /usr/share/Zope-2.3.1/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/share/Zope-2.3.1/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/share/Zope-2.3.1/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/share/Zope-2.3.1/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/share/Zope-2.3.1/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_main) File /usr/share/Zope-2.3.1/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_main) File /usr/share/Zope-2.3.1/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: manage_main) File /usr/share/Zope-2.3.1/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: manage_main) File /usr/share/Zope-2.3.1/lib/python/App/special_dtml.py, line 236, in _exec (Object: manage_main) File /usr/share/Zope-2.3.1/lib/python/DocumentTemplate/DT_In.py, line 666, in renderwob (Object: objectItems) File /usr/share/Zope-2.3.1/lib/python/DocumentTemplate/DT_In.py, line 761, in sort_sequence (Object: objectItems) File /usr/share/Zope-2.3.1/lib/python/ZODB/Connection.py, line 533, in setstate UnpicklingError: (see above) --- and stderr says: 2001-04-05T09:35:45 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\001\034\377' Traceback (innermost last): File /usr/share/Zope-2.3.1/lib/python/ZODB/Connection.py, line 533, in setstate UnpicklingError: invalid load key, 'X'. --- It seems, that there is one Instance in a undefined state which is probably caused by the differences in pickling between Python 1.5 and 2.0.

[Zope-dev] MySQL-python-0.3.5 with ZMySQLDAMike
Hello! There are two copies of the _mysql.pyd file on my disk: the one I built yesterday is here C:\Python20\win32comext\MySQL-python-0.3.5\build\lib.win32-2.0 and there's another one here that I didn't know about here: C:\Python20 I'm not sure where that one came from... Anyway, I took the _mysql.pyd from C:\Python20\win32comext\MySQL-python-0.3.5\build\lib.win32-2.0 and tried putting it in bin/lib But then when I tried to startup zope, it died. No error messages. It just tried to start and then died (on win, this is a console window that opens and closes itself) I then tried putting it in C:\zopes\chikoon\lib\python\Products\ZMySQLDA but had the same results. Sorry to continue with the saga, but at least there's no copy in html this time!

[Zope-dev] 27 million objects.
Hi, Michael. Sorry for taking so long getting back to you. The programmer solving our problems with the post codes has solved it in a different way than what I would've done (his method is way superior), so we're not ending up adding all addresses as Zope Objects. Therefore, I don't have any benchmark tests available. We are going to transfer some 10GB of data at a later stage though (within a month), and that could result in some tests being done - if so, I'll send you an email. :-) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
