[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

The search order is: 1. Instance dictionary 2. Class dictionary 3. Do depth-first search of base classes from left to right. In other words, the search order is the same as for getattr on Python instances, except that some base classes can be in C. Jim -- Jim Fulton mailto:jim@digicool.com Python Powered!

Definately a bug reindex_object

Michel and Catalog gurus, After further exploration I have found that this code reindex the object <dtml-call "propertysheets.Employee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.HourlyEmployee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.Base_properties.manage_editProperties(REQUEST)"> <dtml-call "RESPONSE.redirect('reindex_object')"> but this code does not <dtml-call "propertysheets.Employee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.HourlyEmployee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.Base_properties.manage_editProperties(REQUEST)"> <dtml-call reindex_object> I'll submit it to the collector All my best, -- Jason Spisak 444(a)hiretechs.com

reindex_html bug
by Jason Spisak 20 Mar '00

20 Mar '00

Michel and Catalog gurus, I am using this code to reindex after changing properties. <html> <body> <dtml-if "REQUEST.has_key('first_name')"> <dtml-call "propertysheets.Employee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.HourlyEmployee_properties.manage_editProperties(REQUEST)"> <dtml-call "propertysheets.Base_properties.manage_editProperties(REQUEST)"> <dtml-call reindex_object> <dtml-call "RESPONSE.redirect('index_html')"> </dtml-if> <form action="<dtml-var URL>"><table> <tr><th align=left valign=top>First Name</th> <td align=left valign=top> <input name="first_name:string" size="35" value="<dtml-var first_name>"></td> <tr> <input type=submit value=" Change "> <input type=reset value=" Reset "> </td></tr> </table></form> </body></html> This method calls itself. Why does it not reindex the object, but if I type in reindex_object from the URL location bar it does? I was not aware of this happening until I unzipped 2.1.5 but I cannot be sure that that it the cause. All my best, -- Jason Spisak 444(a)hiretechs.com

ZCatalog stripper work around (catalog_quote)
by Jason Spisak 20 Mar '00

20 Mar '00

Zopists, I would like to write a quote format similar to html_quote and url_quote and sql_quote that makes values insertable into the Catalog so that they can be searched if they contain '+', '-', '.' and other taboos. Can someone give me a place to start? All my best, -- Jason Spisak 444(a)hiretechs.com

Unique meta_types in a folder
by Jason Spisak 20 Mar '00

20 Mar '00

Zopists, Is there anyway to create a list of unique meta_types in a folder without knowing them before hand. I would hate to pack them into a REQUEST variable throught iteration because that would take forever. Some thing like <dtml-in possible_types> <dtml-in "objectValues(_['sequence-item'])"> <dtml-var mycode> </dtml-in> </dtml-in> I am trying to let the viewer sort the view by meta_type but only have the meta_type they ask for show up. Just like the UniqueValuesfor in the Catalog only for a Folder. All my best, -- Jason Spisak 444(a)hiretechs.com

I've try to found document 'aaa' in root of 'www.zope.org' Looked at 'source code' and found '... Traceback (innermost last): ...'. But for me needed no "traceback" and redirecting for example to root as I've tryed above. Or executing of some "dtml-document" or "dtml-method". If I include <dtml-var error_404> (as in below, all of this in "standard_error_message") <dtml-var standard_html_header> <dtml-if error_message> <dtml-if "error_type != 'NotFound'"> <dtml-var error_message> <dtml-else> <dml-var error_404> </dtml-if> <else> and make a dtml-method - "error_404" in which <dtml-var "RESPONSE.redirect('/')">. Then I take the "myhost.dz/error_404" and give true resulting redirect to root of "myhost.dz". But if I try to "myhost.dz/efjklwekljfwejkl" then I give empty document with symbol "/" and traceback in it . Why? Why not redirected to root?
