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.

LocalFS and application/octet-string download problem
by Radek Kotowicz 22 Feb '05

22 Feb '05

Hello, I have a download folder mapped using LocalFS, there were no problems with downloading documents (html,txt) from that directory but there is with programs like setup.exe. When I wget the file I receive a file with the following content: <open file '/home/zoperunner/zopeinstance_1/download/setup.exe', mode 'rb' at 0x42419f4c> instead of the setup file. Log is OK -- 127.0.0.1 56076 - - [16/Feb/2005:12:50:38 +0200] "GET /download/setup.exe" 200 220 "" "Wget/1.5.3" Any hints? Thanks in advance, rk.

programatically adding acl user folder
by Chris H 21 Feb '05

21 Feb '05

Greets; Found a nice program on the net that allows me to import users from another app via xml-rpc and programatically create a new acl user folder in zope. Now while this works seemlessly in 2.6.4 in 2.7x it functions however I cannot enter the folder regardless of what role I have, from the ZMI. Digging around in the code I find this statement at the very end. ---------------------------- security.declareProtected(ManageUsersPermission,'getUser') def getUsers(self): """Return a list of user objects""" return map(self.getUser,self.getUserNames()) ---------------------------- Further digging on the net to try and get an understanding of this, I find Dieters comments here; http://mail.zope.org/pipermail/zope-dev/2002-January/014715.html with a summary of " "declareProtected" requires the wrapping" Im wondering if this is the source of the problem or do I need to look elsewhere? /ch

zopeXMLMethods and Zope 2.7.x
by Francois-regis.Chalaoux＠sanofi-aventis.com 21 Feb '05

21 Feb '05

Hi All, It seems that zopeXMLMethods and Zope 2.7.x do not work correctly together. In fact, installed xml processors are not visible from ZopeXMLMethods object in ZMI (blank list). Personaly I use 4Suite 1.0a4 as processor. Everything work with Zope 2.7.2 but since Zope 2.7.3 every fail. Have you this problem, solutions ? I've patched zopeXMLMethods with the december proposition of zope mailing-list with no succes then the Thread stopped.

DTML html_quoting my JavaScript
by Andrew Maclean 21 Feb '05

21 Feb '05

Hi, I've got myself into a problem with DTML. The system I've been working on uses a lot of JavaScript, which is stored in DTML methods. After 14 months of development, I have been asked to reproduce the installation on another machine, where, unlike the original installation, all my <dtml-variables> are html_quoted, rendering them useless. According to the Zope book, <dtml-vars> are always html_quoted. I know this is not the case because for over a year I could successfully store JavaScripts in DTML methods. Then there is no html_unquote function. I have considered just moving the data.fs file to the new installation but I don't want to do that because 1) I want to know why this problem arose and 2) It's future dated, so I can't pack this database without changing the system time to a future date. (if anyone knows how the date of the data.fs can be modified please let me know) I doubt I'm the first to use DTML to store JavaScript, so if anyone out there knows how to stop it systematically wrecking the code, could you please please please send me some advise. Thanks, Andy Maclean
