I need it like on "microsoft.com". Have some "old links" and "new structure" of site + table with columns "old link" - "new-link". Without creating full house of new documents with "old names" for redirecting to new.

Error 404: Not Found

I have some trouble trying to extend hierarchical structure of my site. If I have "virtual" directory structure, need to call method resolving "Error 404". I've try it. But method "standard_error_message" render only, and no way to catch exception. I don't need to see Zope Error Screen. I want to give up this exception. What you recommend me?

tree tag question
by Jonothan Farr 17 Mar '00

17 Mar '00

This is driving me crazy. I can't for the life of me figure out how dtml-tree is hooked into the template machinery. It looks like the tag is implemented in the class TreeDisplay.TreeTag.Tree. Yet searching for these modules yields only: ---- TreeTag Matches (2) ---- __init__.py (c:\program files\zope\lib\python\treedisplay):import TreeTag TreeTag.py (c:\program files\zope\lib\python\treedisplay):__rcs_id__='$Id: TreeTag.py,v 1.39 1999/11/12 16:25:49 brian Exp $' ---- TreeDisplay Matches (3) ---- Globals.py (c:\program files\zope\lib\python):import TreeDisplay, string Misc_.py (c:\program files\zope\lib\python\ofs): pl=ImageFile('TreeDisplay/www/Plus_icon.gif') Misc_.py (c:\program files\zope\lib\python\ofs): mi=ImageFile('TreeDisplay/www/Minus_icon.gif') Tree has too many matches to list, but none of them match the Tree class listed above. What blows me away is this bit from DocumentTemplate.DT_String: commands={ 'var': Var, 'call': Call, 'in': ('in', 'DT_In','In'), 'with': ('with', 'DT_With','With'), 'if': ('if', 'DT_If','If'), 'unless': ('unless', 'DT_If','Unless'), 'else': ('else', 'DT_If','Else'), 'comment': Comment, 'raise': ('raise', 'DT_Raise','Raise'), 'try': ('try', 'DT_Try','Try'), 'let': ('let', 'DT_Let', 'Let'), 'return': ReturnTag, } No tree!! The in DT_String.parseTag and DT_HTML.parseTag: try: return tag, args, self.commands[name], None except KeyError: raise ParseError, ('Unexpected tag', tag) No exception for 'tree'. I don't see 'parseTag' or 'commands' overridden in DTMLMethod, nor is 'commands' overridden in DT_HTML. This is with Zope version: Zope 2.1.4. The dtml-tree tag does work, I just can't figure out how. Can someone in the know please take a moment to enlighten me? Thanks, -jfarr

Zope 2.1.5 release and *security update*
by Brian Lloyd 17 Mar '00

17 Mar '00

Hi all, Zope 2.1.5 has been released - you can download it from the usual place on Zope.org: http://www.zope.org/Products/Zope/2.1.5/ This release fixes two fairly important security issues that have recently come to our attention: o It was possible for a Zope user with a fair amount of Zope zen and permission to create DTML documents and Folders to circumvent the security machinery within DTML in certain situations, possibly giving the user the ability to use resources that he wouldn't otherwise be able to access via DTML. o It also came to our attention that the DTML code in ZSQLMethod objects was not subject to the same security constraints as the DTML code in DTMLMethods and DTML Documents. The 2.1.5 release fixes both of these issues and we highly recommend that you upgrade, especially if you use Zope for sites that allow untrusted users to create Folders and DTML Documents or DTML Methods. The release also includes a number of recent bug fixes, including the problem in TimeStamp objects that caused the bobobase_modification_time() of Zope objects to appear to be a day behind. Note that this release contains two binary changes, so those running Zope from the source release will need to rebuild the Zope extensions after applying the update. The fixes are also available in CVS and binaries will need to be rebuilt after the update for those of you using CVS. Note that with the 2.1.5 release we will also be releasing "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 (diff releases are not available for win32 for now). 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
