Problems modifying a "global" attribute of a portal tool.
by JoseLuis de la Rosa Triviño 05 Jul '06

05 Jul '06

Hi, I'm working with zope 2.9.1 in debug mode. I have a tool (especifically who_online) where I have created a new class attribute and some methods to modify an read it. A python script is called with a user's click and uses those methods. My problem is that some times when a user modifies the value of the attribute (a python dicctionary) the action takes no effect or it takes effect only in the current transaction. I'm still newbie in zope. The class attribute is called "members_rooms" and the methods are: def joinedRoom(self, member, room): """ Adds the member to the room's list of members. """ self.members_rooms[member] = room logger.info(" %s joined room %s ", member, room) def leftRoom(self, member, room): """ Removes the member from the room where it's supposed to be joined. """ if self.members_rooms.has_key(member): del self.members_rooms[member] logger.info(" %s left the room %s ", member, room) I get log info messages correctly and if I print the value of members_rooms before and after the statement (del or assignment) printed values are correct, but when I query the value of the attribute from a python script just after the "transaction" has finished, the attribute's value has not changed. May some body help me? What am I doing wrong? WhoOnline is a class (and portal tool) that inherits from SimpleItem, Implicit and PropertyManager. Thank you very much.

Rollback and delete weird behavior
by Luiz Fernando B. Ribeiro 03 Jul '06

03 Jul '06

Hello, In a python script I got a structure like this: # Many request checks # A zSQl method deleting some old data cotainer.doDelete(key=key) errors = [ ] for data in list: # Other checks if error: errors.append(error) continue # Inserts in mysql database cotainer.doInsert(data=data, other=stuff) if errors: raise "An Error with list of error: %s" % ', '.join(errors) # --- cut --- The problem is that the raise is not rolling back the delete, looking in mysql log the following sequence was found: --Begin transaction [delete statement] [the insert statements] --Rollback --Begin transaction !! [delete statement again] !! --Commit !!! We tried it many times and revised our code. The only solution was to put the delete statement in weird block like this: if True: cotainer.doDelete(key=key) As if the rollback was only effective against a "2nd level" instruction. This is a really odd behavior but with this trick the rollback was done correctly. Has anyone ever seen this? Luiz Fernando B. Ribeiro

[ANN] TextIndexNG 3.1.10 released
by Andreas Jung 03 Jul '06

03 Jul '06

I am pleased to announce the release of TextIndexNG V 3.1.10 TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Changes in V 3.1.10: - some fixes in the Plone adapters - the TextIndexNG 3 repository has been migrated from CVS to SVN (http://svn.sf.net/textindexng) Requirements: - Zope 2.8+, Zope 3.2+ Download: http://sf.net/projects/textindexng Project page: http://opensource.zopyx.biz/OpenSource/TextIndexNG3 For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the ZPL.

Support Python versions for zope 2.8.7
by kazuo fujimoto 02 Jul '06

02 Jul '06

Hi, there, I read the following comments on http://zope.org/Products/Zope/2.8.7/Zope-2_8_7-released > Support Python versions: > > At this time the only supported and recommended Python versions are 2.3.4 and 2.3.5. > > Using Python 2.4.X is not supported and not recommended at this time. Python 2.4.X will be supported when a security audit took place. This means that you are using Python 2.4 + Zope 2.8 at your own risk. This warning also applies to binary packages that install Zope packages together with a system wide Python 2.4 installation (e.g. Fedora, SuSE...). Such installations are in general not supported. In addition there some third-party products and Python packages that don't work with Python 2.4 and can cause trouble when using Python 2.4. > > -- Andreas Jung (andreas at zopyx dot com) and tried to install zope2.8.7 to my server , whose python is 2.3.4 , and encountred next error message. > > # ./configure --prefix=/usr/local/zope/z287 > > > > Configuring Zope installation > > > > Testing for an acceptable Python interpreter... > > > > Python version 2.3.4 found at /usr/bin/python > > Python version 2.3.4 found at /usr/bin/python2 > > Python version 2.3.4 found at /usr/bin/python2.3 > > > > No suitable Python version found.

database conflict errors
by Jonathan 30 Jun '06

30 Jun '06

During recent load testing of a new application 3.1% to 7.6% of all http requests resulted in conflict errors (3.1% with 10 simultaneous users; 7.6% with 50 simultaneous users). The conflict error occurs when the application attempts to write a small image object into a temporary folder, and each conflict error generates the same traceback: Traceback (innermost last): Module Zope2.App.startup, line 173, in zpublisher_exception_hook Module ZPublisher.Publish, line 121, in publish Module Zope2.App.startup, line 240, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 380, in commit Module transaction._transaction, line 378, in commit Module transaction._transaction, line 433, in _commitResources Module ZODB.Connection, line 484, in commit Module ZODB.Connection, line 518, in _commit ConflictError: database conflict error (oid 0x07, class Products.TemporaryFolder.TemporaryFolder.SimpleTemporaryContainer) I am running Zope 2.9.2 on CentOS 4.3 (linux). Does anyone have any ideas as to what I could do to reduce/eliminate these conflict errors? Thanks, Jonathan

----- Original Message ----- From: "Hans Then" <h.then(a)pythea.nl> >> if you have a python script in the middle of your path, eg: >> folder/pythonscript/somethingelse >> then the pythonscript routine will get executed and 'somethingelse' will > be >> passed in a variable called 'traverse_subpath' >> Create a test python script and try it out (look for traverse_subpath in > the >> REQUEST namespace) >> > What if I don't want that? I can, for instance, call > /folder/pythonscript/title_or_id > /folder/pythonscript/manage_workspace If you want to be sure about the behaviour of your display template I would change the URL to something like: folder/displayroutine?id=objectid and have displayroutine (a script or method) access the object via the parameter id ad generate the appropriate display (based on the type of object it is given). This way you are not going to run into differences in aquisition handling for different types of objects that you are trying to display. Jonathan
