Workaround for objectValues security problem?
by Andres Corrada-Emmanuel 13 Jul '00

13 Jul '00

Hi, I'm trying to create a navigation bar DTML Method that goes something like this: <dtml-let root="PARENTS[-1]"> <dtml-in "root.objectValues('Folder')"> . . . The problem, as reported in a posting from Jerome Alet last week, is that the Anonymous user does not have permission to access the objectValues method. Giving the navigation bar DTML Method the proxy role of manager does not work correctly: the method can be called directly but not within other documents or methods. Does someone have a workaround for this problem? Thank you.

Hi, I want to try out the BTreeFolder product. I unpacked it an restarted Zope, but int the Products-management screen it shows up as a broken product. I use Zope-2.1.4 ... Below is the Traceback it gives me on a click: ----------------------------- BTreeFolder Import Traceback Traceback (innermost last): File "/usr/local/Zope-2.1.4-src/lib/python/OFS/Application.py", line 387, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/Zope/lib/python/Products/BTreeFolder/__init__.py", line 89, in ? import BTreeFolder File "/usr/local/Zope/lib/python/Products/BTreeFolder/BTreeFolder.py", line 89, in ? from AccessControl import getSecurityManager ImportError: cannot import name getSecurityManager ----------------------------- any ideas?

Zope 2.2.0b4: Congrats on a job well done + Tips for upgrading
by T.J. Mannos 13 Jul '00

13 Jul '00

Hi, there, I'd just like to announce that I've installed Zope 2.2.0b4 via CVS and done a complete run-through of my site. It seems to work flawlessly now, and I've gone ahead and installed it on my main port for a trial period. I hope to launch the site using the final version of 2.2.0 (so hurry up, developers!!) :) Anyway, upgrading wasn't without its problems, so let me share with you some tips that will help those in my situation upgrade more successfully. Note that I've skipped some steps, with the assumption that since your upgrading an existing Zope version, you already know how to install Zope. Directories cited: Original installation: /usr/Zope-2.1.6 Fresh install of 2.1.6 (for diff'ing changes I made in the python modules): /temp/Zope-2.1.6 New CVS install of Zope-2.2.0b4: /usr/local/Zope2 (I moved it to the /usr/local volume because I had more space there). Products installed: SQLSession SiteAccess TinyTable ZMySQLDA (your product list may vary) FIRST, I like to hack the source a lot. I have my own special comment tags, such as  instead of <dtml-comment> ... </dtml-comment>, and I have my own special <dtml-var> modifier, js_friendly, which quotes all special characters so I can use them in JavaScript code. On a tip from Shane, I started using CVS to download the Zope source code so that it would merge the changes made in each upgrades with the changes I've made to the source. (Do a search for "CVS" on Zope.org) However, this was my first CVS, so I still needed to bring over the changes I'd previously made. So....... cd /usr/local/Zope2 diff -rc /temp/Zope-2.1.6/lib/python /usr/Zope-2.1.6/lib/python >MyChanges.diff patch -p3 <MyChanges.diff NOTE: Results may vary. By the way, incase you don't want to mess around with CVS (or you're like me and can't figure out how it works), the above commands should achieve the same effect, although you might get a few failed hunks and have to fix them manually. If you don't modify the Zope source, you can skip this step. SECOND, I had all my data, external methods, and installed products on my old installation. I didn't want to lose them. Now, don't be tempted to just copy all your Products over from the lib/python/Products folder. Some of them, such as SiteAccess and SQLSession, if you have them, WON'T WORK. (Furthermore, they'll break your installation, and you won't even be able to get to a management screen). Here's what you do: 1. Back up your new var directory (incase something goes terribly wrong) and copy the old data over. cd /usr/local/Zope2 mv var var.bak cp -R /usr/Zope-2.1.6/var . 2. Copy your external methods over. cp -R /usr/Zope-2.1.6/Extensions 3. Copy *some* (not all) of your Products over. cd lib/python/Products cp -R /usr/Zope-2.1.6/lib/python/Products/TinyTable . cp -R /usr/Zope-2.1.6/lib/python/Products/ZMySQLDA . 4. Start Zope (you may have to modify the startup script and the superuser password) and load the management interface. Delete all your SiteRoots and SQLSessions. You'll have to re-create them. 5. If you're like me, you created all your 2.1.6 objects using the superuser account. You can't do that in 2.2.0. So, go to your acl_users folder and create a new account having Manager and Owner privileges. 6. Download and install new versions of SQLSession, SiteAccess, and possibly ZMySQLDA, if you have it. (Be warned, though, you may have to re-create all of your database connections and SQL methods!) 7. Re-start Zope and log in as the new account you just created. Take ownership of your root directory. (Click "Ownership" tab, then "Take Ownership"). 8. Re-create your SQLSessions and SiteRoots. Check your database folder to make sure your SQL sessions are all intact. (If not, you have no sympathy from me. I had to re-create all 40 of mine when I tried beta 2). 9. Check for bugs -- I'm sure you'll find plenty! If you're getting a lot of Unauthorized errors using external methods, check all your external methods and make sure each class has the property "__allow_access_to_unprotected_subobjects__" set equal to "1". For instance, I had a bunch of simple objects created this way: class simpleClass: pass Under 2.2, I had to do it this way: class simpleClass: __allow_access_to_unprotected_subobjects__=1 pass THIRD, I'm waiting for the next release of Zope so that I can test out this CVS feature. I'm excited! Upgrading is such a pain, and I'm hoping CVS can help to automate that somewhat. I'll let you know how it goes. One very wise thing to do before every CVS checkout, though, is a complete backup of the Zope directory! After four failed upgrades (including the alpha), I don't want to take my chances. Thanks, Zope developers, for an excellent product! - T.J. Mannos - Salt Lake Community College

Hi WorldPilot Users, We just wanted to make a short notice, that we are starting to release alpha Snapshots of WorldPilot.1.1.0. It has various new enhancements, like email composer Address Book lookup, File Archive and others. The newest enhancement is Palm PDA Sync for Linux :-) This version comes along with the WorldPilot Intenet Pocket Sync conduit for Palm(TM) compatible PDAs. It enables you to sync WorldPilot over the net by using a Linux computer. The Current Version supports the Linux and simular plattforms. http://www.worldpilot.org We'll be moving the future WorldPilot Development over to Source Forge in the following weeks, too. Have fun. Cheers, Ryan -- Ryan Hughes <rh(a)n-h.net> Neuberger & Hughes GmbH http://www.n-h.net ___________________________________________________ WorldPilot - Get Synced - http://www.worldpilot.org The Open Source Personal Information Manager Server Powered by Python and Zope - http://www.zope.org

Darn. I had slides for a LUG presentation up on one of my former company's servers, but they seem to have taken the box down. I don't have it archived anywhere. Maybe somebody made a copy? It was from... errr... maybe November last year?

I consider myself a ZOPE newbie, because use I use ZOPE to access some really simple databases.
