You should be concerned, because these are your "Zope" threads that are dying -- eventually, you will have none left to service requests. This problem is a symptom of something inside Zope which is killing off threads, most likely an unhandled exception somewhere. Try turning on the STUPID_DEBUGGER_LOG and see if you get more enlightening log output. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

[ANNOUNCE] Zope 2.1.6 released...
by Brian Lloyd 20 Mar '00

20 Mar '00

Hi all, Zope 2.1.6 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.1.6/ This release fixes a few issues with Friday's 2.1.5 security update release: o Some bits from the currently development branch got into the 2.1.x release branch, causing problems for folks using certain database adapters - this has been fixed. o A fix to Acquisition that happened in 2.1.5 caused a problem with ZClasses, since some of the code in Factory.py previously worked around the problem and now no longer needed to. This has been fixed in 2.1.6. Users of the SiteAccess product should note that the security changes in 2.1.5 necessarily require a change to the SiteAccess product - as he noted in a previous email to the zope list, Evan will be releasing an updated SiteAccess shortly. Also, the XMLDocument product has a buglet that was made effective by a fix to a bug in Acquisition. Prior to 2.1.5, there were cases where acquisition-wrapped objects sometimes didn't have their full acquisition context. This was fixed in 2.1.5. Unfortunately, some applications may depend on the old incomplete wrapping. :( Currently, when you add an XML document, you will get a WrongDocumentException. This can be fixed by changing: if document and ownerDocument and document != ownerDocument: to: if (document and ownerDocument and getattr(document, 'aq_base', document) is not getattr(ownerDocument, 'aq_base', ownerDocument) ): in the appendChild method in class Node in file Node.py. A new rev of XMLDocument containing this fix will be available soon. Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.1.x site. These updates are available for those currently using the 2.1.x source release or the 2.1.x binary releases for either solaris or linux. To apply a differential update to your site: o download the appropriate .tgz file from zope.org o shutdown your Zope process o copy the .tgz to your Zope directory and extract it o run w_pcgi or wo_pcgi *if you are not using a binary release* o restart your process Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Vladimir, I just had this same thing happen, and bypassing the factory worked. I changed the calling method from calling "maClass_factory to myClass_addForm, and the add method worked fine.

retrieving variables from an earlier form
by Joe Hewitt 20 Mar '00

20 Mar '00

I'm trying to create several screens to allow my technician to keep a log of problem reports. I chose to create a search form. The data will display in the usual table form and the user will select the item wanted for display in an update form with the values shown as default field values. In the table view, I created a link to my next form in the following way: <a href="http://localhost:8080/School/Admin/Computer/displayitem?id=<dtml-var id>&Submit=Submit&Query"> The problem is that no data gets stuffed into the values="" attributes of the form which leads me to believe that either I'm not using the <dtml-sqlvar> tags correctly or I'm not calling the data selected from the database (mysql) for use in the new form correctly. I read the how-to on inserting sql data, but I want to create a form that will update existing records. Any help will be appreciated, Joe

Brian, It appears to be a good fix. I'll run with it and let you know how it goes. I suppose that I should cc the list as well. Curtis >>> Brian(a)digicool.com 03/20/00 10:50AM >>> Hi Curtis - We are going to be releasing a fixed update today - in the meantime, if you could try something out to verify that it fixes your problem as well, that would be great. I've attached a file ZRDB.tgz. If you copy that to your lib/python/Shared/DC/ZRDB directory and unpack it, then restart Zope you should be working again. If you have a minute to try this can you let me know how it goes? Thanks!
