Publish.py / publish hack
by Pierre-Julien Grizel 30 Oct '00

30 Oct '00

Hi, I'm using Zope 2.2.2 and for some personal reasons I need to patch the publish function from Publish.py. I used the usual __init__.py straegy to patch ZPublisher : from MyModule import Mypublish import ZPublisher.Publish from ImageFile import ImageFile # Patch the original publish function ZPublisher.Publish.publish = Mypublish But the fact is, publish is called several times at several places in the source code, and especially from the publish_module function when an exception is raised... And, although my patch works most of the times, it doesn't work when an exception is raised. I may need to replace another 'publish' reference somewhere, but does anyone know WHERE exactly ?? Many thanks, P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail.

siteaccess, hosting etc, sanity check
by Jonathan Cheyne 30 Oct '00

30 Oct '00

Hi all, just a bit further down my vhosting journey ... got apache ProxyPassing and siteaccess installed but something is missing. I type in my vhosted domain www.red.com which (correctly) goes straight to /red and shows the index_html contents *except* images which show broken. The source shows that they (correctly) are trying to load from www.red.com/imagename which is right. This image is in /red along with the index_html. Also the one link to a dtml document in the /red directory is also broken. If I suppress siteaccess then everthing works from the initial www.red.com but only because the links and images are loading from the 'master site url'. you can click but then the url obviously gives the game away. so proxypass works. What I dont get is why I can see the body text in index_html, which lays out the page but not the image embedded in the page? my various settings ... NameVirtualHost 111.222.333.444 <VirtualHost 111.222.333.444> ServerName www.red.com ProxyPass / http://www.blue.com:8080/red ProxyPassReverse / http://www.blue.com:8080/red </VirtualHost> then in /red we have a siteroot with the following title: base: http://www.red.com path: / www.blue.com and www.red.com both point to 111.222.333.444 and the box also has the www.blue.com as its host name which zope recognises on start iup. a bit stuck.

Website develoment with CVS Zope?
by Jimmie Houchin 30 Oct '00

30 Oct '00

I am about to begin development and would like to use the CVS version of Zope. I have already setup my /usr/local/Zope/Zope2 directory and gotten Zope via CVS. When I have it install Zope and begin development are what issues or problems will I have when I do an update? I know because I will be developing and changing files in these directories but not via CVS that CVS will probably complain about the changes. Is this a problem? I will also be wanting to use the CVS of other Zope items like the PTK. Does this impact this in any way? How do those of you who develop using the CVS version do it? Any advice or best practices? Thanks for any help. Jimmie Houchin

Verify Watermark.
by Hannes Grund 30 Oct '00

30 Oct '00

In Zope2.1.6 there was a function called 'verify watermark' in module Accesscontrol.User. This function seems to have gone in the 2.2.2 release. My question: Is there any direct replacement for this method ? Or at least a some kind of equivalent code ? thanks in advance, Hannes

Login Manager problem
by Luca Mearelli 30 Oct '00

30 Oct '00

Hello, I posted this some days ago on zope-ptk and zope-dev mailing list, but got no response, so I thought I've sent it to the wrong mailing list, here is waht happens, and a possible solution :-) I had a strange problem when trying out LoginManager v0.8.8b1 with the latest cvs Checkout (as of Oct.23), here is the traceback trying to add a LoginManager (The form didn't show up): Error Type: NameError Error Value: path ... Traceback (innermost last): File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/tmp/Zope2/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/tmp/Zope2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/App/special_dtml.py, line 120, in __call__ (Object: addLoginManager) (Info: /usr/local/tmp/Zope2/lib/python/Products/LoginManager/addLoginManager.dtml) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: UserSourcesMetaTypes(this())) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_Util.py, line 331, in eval (Object: UserSourcesMetaTypes(this())) (Info: UserSourcesMetaTypes) File /usr/local/tmp/Zope2/lib/python/ZPublisher/HTTPRequest.py, line 772, in __getitem__ NameError: (see above) after looking at the LM code I found that the manage_addLoginManagerForm is defined in LoginManager.py: ... manage_addLoginManagerForm = HTMLFile('addLoginManager', globals(), UserSourcesMetaTypes = PlugInFinder(LoginManager.UserSourcesGroup), LoginMethodsMetaTypes = PlugInFinder(LoginManager.LoginMethodsGroup)) ... At first I thought it could have been a LM problem, removing UserSourcesMetaTypes(this()) let the form appear, but when I focused on the UserSourcesMetaTypes work, and how the user sources PlugIns get installed I found nothing (It was actually my first test with LM & ZPatterns), moreover there was no mention of such problems by anyone else on the Mailing Lists. Then I tried to it on a Zope 2.2.0 (released) and it worked fine adding the LM. So it should have been something with my Zope CVS checkout, when looked at the HTTPRequest.py file at the line shown in the Traceback, i found a possible error with "__getitem__" When it tries to return the value of UserSourcesMetaTypes, it enters the "if key[:1]=='U':" at line 760 since UserSourcesMetaTypes starts with 'U', but match is empty, therefore path is not initialized and at the line 772 we have the NameError. Putting the lines 772-774 inside the "if match is not None:" fixed the problem (I included a diff for this), is it the right way to go, is it enough? I think so but I have a small knowledge of Zope internals so I'm not completely sure i.e. if we want to match only the env.variables starting with "URL" why not even change the "if key[:1]=='U':" into "if key[:3]=='URL':"?

Multiple Inheritance and the Portal Base classes.
by Steinar Rune Eriksen 30 Oct '00

30 Oct '00

Can anybody see why I get the following error ? I try to subclass DemoPortalBase and PortalObjectBase into a class CMyPortalBase which I again subclass with a Zope ZClass. It all works fine until I add another class in the inheritance list of CMyPortalBase.When I try to call its __init__ method with the "self" argument if does not recognise this as the instance variable ? (I tries to print self, and it says that this is an instance of my ZClass). In other Python programs, calling Parent.__init__(self) works fine, but when running through Zope in this context Error Type: TypeError Error Value: unbound method must be called with class instance 1st argument class CMyPortalBase(TemplatePage.CTemplatePage,Portal.DemoPortalBase, PortalObject.PortalObjectBase): def __init__(self): TemplatePage.CTemplatePage.__init__(self) The CTemplatePage class is as follows : class CTemplatePage: standard_html_header = Globals.HTMLFile("StandardHeader", globals()) standard_html_footer = Globals.HTMLFile("StandardFooter", globals()) def __init__(self): print "In CTemplatePage" ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
