New zope.org status update
by Brian Lloyd 02 Aug '03

02 Aug '03

Hi all - Well the migration script is running great -- as it has been since 10a this morning :) It's currently converting member folders for users whose names start with 's' - so it has a little while still to go. It's a few hours over what I guesstimated it would take and still working, so I think I'm going to shoot for going live on Saturday. As exciting as it is watching names roll by in the log, I don't think it buys us much to go live at 4am vs. later on Saturday :) Brian Lloyd brian(a)zope.com V.P.

NOTICE: Final content migration and transition to new zope.org begins today!
by Brian Lloyd 01 Aug '03

01 Aug '03

Hi all - sorry for the wide cross-posting, but I want to be sure that the word gets out. Starting today, we will be starting the transition of zope.org to a new look and a new platform. We plan to do the final content migration later today, so if you are a frequent content contributor to zope.org, you may want to hold off on new additions until the new site goes live (expected to be Friday). I've put a prominent notice on the current zope.org homepage with the same info. Thanks, and we'll see you on Friday with a new zope.org! Brian Lloyd brian(a)zope.com V.P.

getting parent in product
by Christopher N. Deckard 01 Aug '03

01 Aug '03

Hello, I've written a ZMI configurable PutFactory Product to allow our users to be able to configure what types of objects are created when files are PUT using WebDav. What I would like to add is the ability to call a script immediately after the object is created. The script could do things like auto-catalog images in a ZCatalog or send out an email every time a file is uploaded. Looking at the code in webdav/NullResource.py NullResources.PUT(): ob = (factory(name, typ, body) or self._default_PUT_factory(name, typ, body) ) # We call _verifyObjectPaste with verify_src=0, to see if the # user can create this type of object (and we don't need to # check the clipboard. try: parent._verifyObjectPaste(ob.__of__(parent), 0) except Unauthorized: raise except: raise 'Forbidden', sys.exc_info()[1] # Delegate actual PUT handling to the new object. ob.PUT(REQUEST, RESPONSE) self.__parent__._setObject(name, ob) RESPONSE.setStatus(201) it doesn't look like I can do what I'd like to do without overriding NullResource.PUT(). Any thoughts on how to accomplish this? Thanks, -Chris -- -------------------------------------------------------------------- Christopher N.

I reinstall it again and the problem is gone now. Perhaps the patches of windows, which I installed just after installing this product, did something wrong.

NewBie DTMl Help
by S K Rahman 01 Aug '03

01 Aug '03

Hi all, I am trying to learn and if possible migrate some of my office apps to zope. The trouble is somewhere here From Index_html page I am using a input form to get the login, password so that it can authenticated of the currently internal central auth system. The form is posted to login_verify having content as follows. The Authenticate_user is a ZSQL method taking user ID as parameter and is supposed to return password, name and access level of that user. <dtml-in Authenticate_user> <dtml-if expr="password==upassword"> Auth success <dtml-call RESPONSE.redirect('main')> <dtml-else> Auth Failed </dtml-if> </dtml-in> Unfortunately I dot get Auth Sucess but the redirect never happens. I tried earlier this using dtml-call instead of dtml-in but soon I realized that dtml-call does not return any values I need the output of password, access level so that I can set the apporiarte permissons on the respective page. Please advise. Regards

Problem setting up an apache proxy to Zope's webDAV service.
by Alex Coventry 01 Aug '03

01 Aug '03

Hi. I have the following rewrite rule in my httpd.conf: RewriteRule ^/webDAV(.*) http://localhost:1981/VirtualHostBase/https/coventry.mit.edu:443/webDAV/Vir… [L,P] This proxies webDAV requests for https://coventry.mit.edu/webDAV/ to the zope service running on port 1981. Attempting to open that URL in the webDAV client Goliath results in these requests being recorded in Z2.log: OPTIONS /VirtualHostBase/https/coventry.mit.edu:443/webDAV/VirtualHostRoot/ HTTP/1.1 PROPFIND /VirtualHostBase/https/coventry.mit.edu:443/webDAV/VirtualHostRoot/ HTTP/1.1 However, this results in a Not Found error. The full record from the error log is at the bottom of this email. It seems to be failing on an attempt to access https://coventry.mit.edu/PROPFIND. Why it has decided to try to access the webDAV method as if it were part of the URL is beyond me. I'd be grateful to anyone who could tell me what I'm doing wrong here. Alex.

Performance requirements and ZEO
by bart hubbard 01 Aug '03

01 Aug '03

I'm working on a project to build a public website using Zope, and am in a position where I need to spec and order the hardware before beginning the work on the site. We're going to plan for 500,000 hits/day as a benchmark. I'm leaning towards a ZEO configuration, with a dedicated ZEO Storage Server and 2 ZEO Client machines, with a load-balancer up front. This way, the worst case is the performance isn't up to par, and I can just toss another machine at it as a ZEO Client. Here's the question: is there any benefit to having dual-processor machines on any of these? I think we can afford 3 of them, if necessary, but is it even needed? I was planning on going with Dual-Xeon 2.8 GHz boxes running Linux. I'd rather not run more than one instance of Zope on the clients, btw. Also, I'm having trouble finding info on getting SSL working in a ZEO setup. Are there any docs out there I should read? much thanks, bart

Permission for packing database
by Marc Burgauer 01 Aug '03

01 Aug '03

I would like to set up a CRON job to daily pack a Zope database. The application does some heavy text processing and consequently the database can grow half a gig per day just because of keeping all the transactions, while the data to keep is just a few megs. Because I have to type the password in clear text into the script for CRON (I intend to use wget), I'd like to create a user with a dedicated role that can do nothing, but do the packing. I could not find which permission is required for this. Can anybody tell me what the minimum privileges are for packing the database? OR can the superuser account be used for this? (With packing I mean: /Control_Panel/Database/manage_pack) Cheers Marc

More verbose undo/transaction desciptions
by Carsten Gehling 01 Aug '03

01 Aug '03

Is it possible to make the Undo tab's list of transactions more verbose? Say that I change the value of one property of an object, and then at a later time change another property of the same object. In the object's Undo tab, there's only displayed, that I called the "editTheObject-something" method twice, not which properties that were changed. Is it something that I tweak in my product's code? - Carsten

Disappointed by VerboseSecurity
by Eugene Morozov 01 Aug '03

01 Aug '03

Hello! I've just installed VerboseSecurity product to resolve problems with my site but it doesn't print anything really useful: Unauthorized: Your user account does not have the required permission. Access to 'title' of (DTMLDocument instance at 8fb4738) denied. Your user account, Anonymous User, exists at /acl_users. Access requires one of the following roles: ['Authenticated', 'Manager']. Your roles in this context are ['Anonymous']. (Also, an error occurred while attempting to render the standard error message.) But I want to know access to `title' of which DTML Document is denied. I have plenty of DTML Documents including each other and methods querying `title' property. :(( Eugene
