ZCatalog FieldIndex Bug
by Chris Withers 06 Apr '01

06 Apr '01

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

What should I try next? Thanks, Michael Bernstein

Possible ZCatalog Bug
by Edmund Goppelt 06 Apr '01

06 Apr '01

A ZCatalog when passed an empty mapping of search terms returns no records found in Zope 2.3.1, instead of all records. This is not the way I remember ZCatalog working in previous versions of Zope. Is this a bug? Too, can someone clue me in on the proper place to look for bugs in Zope before posting an email like this one? I really hate to take up people's time raising known bugs. Maybe I just don't know how to use it, but the bug collector seems to be out of date or broken or both. -- Ed Goppelt

dtml-in performance
by Brett Carter 05 Apr '01

05 Apr '01

What can I do to maximize the peformance of a dtml-in statement? When iterating over a 2000 row database query, it takes about 20 seconds - time mostly spent doing security checks, and calling __getitem__ in DT_InSV.py. Is the performance of dtml-in just slow? -Brett

Trouble with ZODB when switching between Zope-releases with Python 1.5 and Python2.0
by Ulrich Eck 05 Apr '01

05 Apr '01

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. Is there a way to find out which object causes this error and delete it ???? thanks for your help Ulrich Eck net-labs

MySQL-python-0.3.5 with ZMySQLDAMike
by Mike Blake 05 Apr '01

05 Apr '01

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 <zopedir>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! I apologize to everyone for that... bye! mike blake phil wrote: > RE: [Zope-dev] MySQL-python-0.3.5 with ZMySQLDAMike, > You need to put the file _mysql.pyd into your PYTHONPATH. > Try putting it into the same folder as the ZMySQLDA or into > <zopedir>bin/lib.
