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

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

I can, for instance, call /folder/pythonscript/title_or_id /folder/pythonscript/manage_workspace There the behaviour you describe does not occur. Regards, Hans Then

Acquisition? problem
by Hans Then 30 Jun '06

30 Jun '06

Hi all, I am writing a small object browser for the EPOZ toolbox. In the browser I have a tree of object references. Clicking on the tree should show more details of the selected object. I have created a template details that should show the details of the object, like this: /folder/selected_object/details This is all TTW code by the way. The template works fine for most values of selected_object, but for some it fails. It fails for at least PageTemplates and Python Scripts. For those objects, calling the details template will simply show the normal output of the object. Any ideas on how to solve this? Regards, Hans Then

Hi, How can I save blob data in SQLServer using ZSQLs? I'm using mxODBC. I have a ZSQL that looks something like this: > update > table_name > set > blob_data = <dtml-sqlvar "i_blob_data" type="nb"> > where > conditions.... But I get the following error when I run the above ZSQL: > ProgrammingError: ('07002', 0, '[Microsoft][ODBC SQL Server > Driver]COUNT field incorrect or syntax error', 6108) Any comments will be much appreciated. thanks, Satchit

ConflictError with *one* ZEO client?
by Richard Jones 29 Jun '06

29 Jun '06

I've got a zopectl script I'm trying to run with the "zopectl run" command. It crashes out with a ConflictError even if there are no other ZEO clients connected to the ZEO store. I've restarted the ZEO store, no change. Any advice? Ideas? Richard

Improved Zope Org Proposal
by John Schinnerer 28 Jun '06

28 Jun '06

Aloha, ... >> I start to understand: >> >> You want to have a narrow, a focused site >> because you fear that a bigger one cannot be managed. >> >> In such a case, I would say: start with the small solution >> and maybe get bigger later. This is a basic principle of design that works (as opposed to design that fails to work). Start small and work the edges outwards. The "work edges outwards" that works is often modular in nature (perhaps a.k.a. 'micro-sites'). That doesn't mean it can't look-and-feel like "one big site as access point." Biting off more than one (person, organization, whatever) can chew usually results in choking... So I actually see a lot of agreement in what may appear to be argument. Also: I agree that despite the wonders of zope, the zope.org site is not as stunning a place to refer people to as it could be. For the most general public face of the site, I support the idea of a clear and simple "brochure-like" approach. A couple major open source project/product sites that I am excited about referring people to: http://rubyonrails.org http://www.mozilla.com ...and to some extent http://www.openoffice.org ...although IMO the OO site is not quite as clear and well-designed as the other two...better than zope.org though. Also bearing in mind that the Ruby On Rails site is for a development platform while Mozilla and OO are end-user app sites - somwhat different audiences. cheers, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net
