Zope and threads.
by Pascal Peregrina 22 Feb '05

22 Feb '05

Hi, I need to have some processing done in one thread, that will set some attributes of a (non persistent) object. This processing is completely independant from Zope objects. Zope objects (persistent or non-persistent) will only need to "read" data from this object. What would be the best way to do this (specially how to initialize my thread ?)

zope rewrite problems.
by Wombie Tomek 22 Feb '05

22 Feb '05

can someone tell me what i'm doing wrong? i'm trying to use zope behind apache but i'm having some odd troubles. my site works with the current rewrite rule for the most part but any query strings thrown to the site result in weird errors. for example searches do not work, language switching, zphotos... i have a standard virtualhostmonster and my rewrite rules in apache look something like this: RewriteRule ^/(.*) http://www.thoracicavity.com:8085/VirtualHostBase/http/ www.thoracicavity.com:80/wombie/VirtualHostRoot/$1 [P,L] the site is of course... www.thoracicavity.com

using a ZODB standalone app with Zope
by Istvan Albert 22 Feb '05

22 Feb '05

Hello All, I'm trying to migrate a ZODB standalone application for use in Zope. I have a module that instantiates a ZODB storage upon import and then has module functions that return the root for this database. --- storage = FileStorage.FileStorage(Config.DB_FILENAME) db = DB(storage) def get_root(): conn = db.open() return conn.root() def commit(): get_transaction().commit() --- The current setup does not work in Zope, I get timeout errors and I'm guessing that the two databases interfere somehow. What I plan to do is to make use of the database created by Zope instead. In a python script how would I go about fetching the root of the database that is used by Zope. thanks, Istvan.

Why I must set security-property "Access contents information" to get Data from Database?
by Patrick Ulmer 22 Feb '05

22 Feb '05

Hi, I have protect my folder by using acl_users. But now I must allow access by anonymous to one DTML-Document. This document uses <dtml-in> to get data from my MySQL-Database. To allow acces I have to set the following security properties: 1. DTML-Document: View 2. Z-SQL-Method: Use Database Methods 3. Parent Folder: Access contents information Is that right? 1 is for viewing HTML. 2 and 3 for access Database. I'm not realy sure, why I must set 3? Can somebody explain it? Thanks, Patrick

That can't be done in the general case. Indeed, but I'm looking to service the situation where there's already a table with columns x,y, and z that I'd like to become a folder of content objects with x,y,z. Yes, the functionality would be in a python class, but that might be somethign fairly generic, like the PropertyManager interface... possible? cheers, Chris PS: How's the CA mapper for APE coming? -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Corrupted data.fs
by Marco Bizzarri 22 Feb '05

22 Feb '05

Hi all. We're experiencing nightly corruption of a Data.fs in an intranet application. We've removed all the packing/backup stuff, we've moved from zope 2.6.4 to zope 2.7.4, but we still have data corruption in the morning. Here is the error from the event log: 2005-02-22T09:21:51 ERROR(200) ZODB Couldn't load state for 0x3b3939 Traceback (most recent call last): File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 663, in _load doid, serial, prev, tloc, vlen, plen = unpack(DATA_HDR, h) error: unpack str size does not match format ------ 2005-02-22T09:22:07 ERROR(200) ZODB Couldn't load state for 0x3214dc Traceback (most recent call last): File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 663, in _load doid, serial, prev, tloc, vlen, plen = unpack(DATA_HDR, h) error: unpack str size does not match format ------ 2005-02-22T09:23:01 ERROR(200) ZODB Couldn't load state for 0x0eed Traceback (most recent call last): File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 597, in setstate p, serial = self._storage.load(oid, self._version) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 689, in load return self._load(oid, version, self._index, self._file) File "/home/zope/zope-2.7.4/lib/python/ZODB/FileStorage.py", line 665, in _load raise CorruptedDataError, h CorruptedDataError: ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ I'm quite confident the problem is outside of Zope, but I would like to have some pointer on where to investigate in order to undestand the problem.
