Bug in DateTime arithmetic
by Jeff K. Hoffman 12 Apr '99

Hello, everyone. While messing around with Zope, I came across a bug in the DateTime class. The following python session exhibits the faulty behavior: Python 1.5.1 (#1, Dec 11 1998, 07:16:57) [GCC 2.7.2.3] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> from DateTime import * >>> >>> date = DateTime('05/01/1999').earliestTime() >>> d = (date - date.day()).earliestTime() >>> print d 1999/04/30 00:00:01 US/Eastern >>> print (d - 24) 1999/04/06 00:00:01 US/Eastern # correct >>> print (d - 25) 1999/04/05 00:00:01 US/Eastern # correct >>> print (d - 26) 1999/04/03 23:00:1 US/Eastern # incorrect >>> d = d - (d.day() - 1) >>> print d 1999/03/31 23:00:1 US/Eastern # incorrect >>> ^D Apparently, the DateTime code is picking up an extra hour somewhere which is throwing the calculation off. I've submitted this to the collector, but I am posting it here for discussion. Anyone know what the problem might be? I'm willing to fix it and submit a patch, but right now I have no clue where to look. jkh

Making a Product has crashed my serve.py/and or Zope
by Jason Spisak 11 Apr '99

11 Apr '99

Hey gang, Boy do I suck. I am making a product called Copmany and it's meta-type is called Company as well, for reasons best not discussed, I started from scratch again and was creating another one called Company with metaa-type company. Well needless to say Zope won't start now because as soon as I created two products with the same meta-type I died. Does anyone know how to change the meta-type or fully delete the old Company product from start-up when Zope registers products? All the best, Jason Spisak webmaster(a)mtear.com

This is the difference, in my sandbox I have the full set of permissions. I would suggest checking out a Zope from CVS to test NotMail and IMAPAdapter as this is the version that they have been tested and developed against. Neither NotMail nor IMAPAdapter will be releases as "official" (read: 1.0) until Zope 2.0. Till then they're beta code when used with a recent Zope checkout. When used with 1.10.2, who knows. In fact, I'll state clearly in the README's that a CVS version is required. This way I won't waste *your* valuable time. <snip> > (I'm running Zope 1.10.2 win32) > > Sorry, an error occurred.<p> > <!-- > Traceback (innermost last): > File D:/ZopeOne\lib/python\ZPublisher\Publish.py, line 877, in > publish_module > File D:/ZopeOne\lib/python\ZPublisher\Publish.py, line 515, > in publish > (Info: Imap/Hayden) > File lib/python/Products/IMAPAdapter/IMAPAdapter.py, line 208, in > validate > (Object: Navigation) > AttributeError: __getslice__ > This is because there is no View permission restriction, your auth info is 'None', which, of course, has no __getslice__ method. -Michel > > Brad Clements, bkc(a)murkworks.com (315)268-1000 > http://www.murkworks.com (315)268-9812 Fax > netmeeting: ils://ils.murkworks.com ICQ: 14856937 >

We have tought about the possiblities of a quota mechanism (which is harder than it sounds, because of the overhead of checking size limits on *every* request), but it sounds like what your looking for is the Zope equivalent of the UINX 'df' command. You can take a look at the find machinery, and then add a __len__ method to *every* object and put the two together to make a 'df' like method for OFS.Folder.

Thanks > Install IMAPAdapter and NotMail (use the latest beta of NotMail 0.1.1, which fixes an unrelated DTML bug) http://www.zope.org/Download/Prereleases/Mail Create a NotMail, in your case called Hayden Create a Role in that NotMail called NotMail Check the 'View' Permission for the Role NotMail in the NotMail folder (alternatively, you can create the role and check the permission in a higher level folder, like your /Imap folder) *In a different browser* meaning not in the same browser or in another instance of the same broswer you are managing the Zope from, go to /Imap/Hayden. Log in with the imap userid and password. If you use the same browser you manage Zope with, it *will not* work. I use linux so I just run a netscape as a different user, or use my other computer (which is NT :( ), or start a netscape on another machine and X it over.

zope's zen - mapping web site to programming environment
by klm＠digicool.com 08 Apr '99

08 Apr '99

As i've been getting a sense of zope (i'm slow, i know), i'm enjoying seeing a model that pulls it all together for me. It may be obvious to anyone that has zope's zen - or it may be just plain wrong ("jpw"). I wonder, and wonder how it registers on you all. So... My realization is that for the programmer, below the content- management functionality, zope translates the framework of object- oriented programming onto the framework of a web (or other document publishing) site. (From stray comments i gather that bobo more obviously did this, and that zope is increasingly getting back to that point, making this all easier to apprehend and use.) - Acquisition turns the document hierarchy into modular programming scopes: - Folders are sorta like python modules and class objects. - Documents are routines - folder methods - with literal and dynamic content - External Methods correspond to python's extension builtins - Components (formerly Products) correspond to pythons extension modules - These scopes provide the programming-environment namespace in the structure of the site, enabling hierarchical sharing routines and state information (like user permissions) through that stucture. - Mapping of URLs onto method invocations provides a call structure for calling into the document hierarchy namespaces. - DTML brings together the textual and procedural roles of documents at a Zope site, providing the way to express the active versus literal portions as web-site document "templates". If this view is on-base, i would structure something describing the "Zen of Zope" around this mapping of programming constructs to web sites/document hierarchies. And if this is on base, i can see one way to formulate a marketing message: This translation of object-oriented programming onto a web-site structure enables geeks (and adventurous others) to bring the power of programming more directly to any web-site publishing application. What this means for content managers is an already rich environment of facilities that does the regular things easily and well, and can be made to do anything that can be programmed, if they need something extraordinary. Open source only enhances the evolutionary process, enabling sharing and eventual incoporation of new solutions for common needs... Ken klm(a)digicool.com

Anyone have IMAPAdapter working?
by Brad Clements 08 Apr '99

08 Apr '99

It looks like my NotMail can't get tree to recognize the imapFolderTree in ImapAdapter. In folder /Imap, I created a Notmail object called "Hayden". When I access /Imap/Hayden I'm prompted for my userid and password (which happens to match my access file entry, btw). I then get this traceback. (also, if I use a different userid that is only on the imap server, I get "you are not authorized" however I think I have all permissions turned on for IMAPUser). If anyone has a step-by-step installation process, I'd appreciate seeing it. Thanks  </body> </html> <!-- Traceback (innermost last): File D:/ZopeOne\lib/python\ZPublisher\Publish.py, line 877, in publish_module File D:/ZopeOne\lib/python\ZPublisher\Publish.py, line 590, in publish (Info: Imap/Hayden/imap_menu) File D:/ZopeOne\lib/python\OFS\DTMLMethod.py, line 157, in __call__ (Object: imap_menu) File D:/ZopeOne\lib/python\OFS\DTMLMethod.py, line 153, in __call__ (Object: imap_menu) File D:/ZopeOne\lib/python\DocumentTemplate\DT_String.py, line 513, in __call__ (Object: imap_menu) File D:/ZopeOne\lib/python\DocumentTemplate\DT_With.py, line 138, in render (Object: AUTHENTICATED_USER) File D:/ZopeOne\lib/python\TreeDisplay\TreeTag.py, line 152, in render (Object: a tree tag) File D:/ZopeOne\lib/python\DocumentTemplate\VSEval.py, line 200, in eval (Object: imapFolderTree(REQUEST)) File <string>, line 0, in ?
