Upgrade to 2.5.0 breaks site: TypeError: object of type 'string' is not callable
I'm running into strange trouble with one site when I try to upgrade it from Zope 2.4 to 2.5.0. With 2.4 (up to 2.4.4b1), the site works fine. Now when I upgrade Zope to 2.5.0 (or 2.5.1b1), I get an "TypeError: object of type 'string' is not callable" whenever I try to access the site (see below). Furthermore, running the Data.fs ZODB with 2.5.x once seems to corrupt it! I.e. when I move back the Data.fs to 2.4.4b1 (where it had worked before), it suddenly fails with the same error! This is the error message: Site Error An error was encountered while publishing this resource. TypeError Sorry, a site error occurred.

Please try the following in your unbroken 2.4.4b1, and then in 2.5: 1. Go to your ZOPE/lib/python directory 2. Start Python 3. Type these commands:
import Zope app = Zope.app() print app.__before_traverse__ print app.__before_publishing_traverse__._list
What does it print? Cheers, Evan @ Zope
Hi Gregor, I'm not sure about the initial problem you're having, but I can help you move FileStorages back and forth between 2.4 and 2.5 without "corruption". To use the "corrupted" Data.fs that came as a result of using a 2.4 Data.fs under 2.5, and then going back to 2.4 with the same Data.fs (actual symptom: AttributeError: __call__ in line 171 of BeforeTraverse.py), use this small MonkeyPatch product into your 2.4 instance: http://www.zope.org/Members/mcdonc/Products/MultiHookMonkeyPatch . 2.5 inserts an instance of a class as a traversal function that does not exist in 2.4; this patch creates a "dummy" class definition that allows you to start the site again and delete the 2.5-specific objects that get added to the root (temp_folder, session_data_manager, browser_id_manager). - C ----- Original Message ----- From: "Gregor Hoffleit" <gregor@hoffleit.de> To: <zope@zope.org> Sent: Wednesday, March 06, 2002 8:31 AM Subject: [Zope] Upgrade to 2.5.0 breaks site: TypeError: object of type 'string' is not callable
I'm running into strange trouble with one site when I try to upgrade it from Zope 2.4 to 2.5.0.
With 2.4 (up to 2.4.4b1), the site works fine. Now when I upgrade Zope to 2.5.0 (or 2.5.1b1), I get an "TypeError: object of type 'string' is not callable" whenever I try to access the site (see below).
Furthermore, running the Data.fs ZODB with 2.5.x once seems to corrupt it! I.e. when I move back the Data.fs to 2.4.4b1 (where it had worked before), it suddenly fails with the same error!
This is the error message:
