Problems with <dtml-tree>
by Ian Clarke 19 Oct '99

19 Oct '99

Hi, I have been trying to create a site making use of the dtml-tree tag. To get started I tried to follow the "Inplementing a navigation tree" section of the Zbook tutorials. I entered everything more or less exactly as was printed (I made some changes to the HTML output). Everything seems to display correctly when I initially view the page (a tree of my "Outline" folder is displayed), however whenever I click on any of the sub-folders I get the error to be found at the end of this email. Can anyone give me a pointer as to what is going wrong? Also, on a general point - is there any effort being made to make the error reporting system more newbie friendly? Ian.

Simple newbie question
by Ian Clarke 19 Oct '99

19 Oct '99

Hi, sorry about the undescriptive title, but I couldn't think of a consise way to describe what I want to do, although I am sure that it is a simple thing. Basically I have a SquishDot site within a folder on my zope installation, but I want users to go straight to that site when they look at http://www.mymachine.com/. I (or think I know) how to make zServer run from port 80, but I can't figure out how to make a "shortcut" between the root of the site and the SquishDot folder. I don't want people to have to look at http://www.mymachine.com/squishfldr to see the site, which is the case at present. Any suggestions are most welcome, Cheers, Ian. -- Ian Clarke Email: I.Clarke(a)strs.co.uk Homepage: http://www.gnu.demon.co.uk/ Also see: http://freenet.on.openprojects.net/ "All we see and all we seem is but a dream within a dream"

ZWeather strategy
by Tim Wilson 19 Oct '99

19 Oct '99

Hi everyone, I'm working on a portal-like site and I'd like to display the current weather conditions on the main page. There are hundreds of stations in the U.S. (don't know about the rest of the world) that have the current weather as part of the METAR system of the National Weather Service. The reports can be retrieved from http://weather.noaa.gov/weather/metar.shtml or by anonymous ftp at ftp://weather.noaa.gov/data/observations/metar In either case you need to know the 4-letter ICAO code for your location. Can anyone recommend a strategy for this task? Some external method that goes out and grabs the latest weather codes perhaps? ZClient? I would really appreciate a suggestion. I'm still a Zope and Python newbie, and I figure this would be a good problem to work on. Thanks. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Selection properties - how?
by Itamar 18 Oct '99

18 Oct '99

I want to add a Selection property to an object. What format to I write the multiple values in - I must be doing something wrong, cause every time I try to make a selection property I get the following error: Traceback (innermost last): File /itamar/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /itamar/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /itamar/Zope-2.0.1-linux2-x86/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /itamar/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 165, in publish File /itamar/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addProperty) File /itamar/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addProperty) File /itamar/Zope-2.0.1-linux2-x86/lib/python/OFS/PropertyManager.py, line 274, in manage_addProperty (Object: ElementWithAttributes) File /itamar/Zope-2.0.1-linux2-x86/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_propertiesForm) (Info: /itamar/Zope-2.0.1-linux2-x86/lib/python/OFS/properties.dtml) File /itamar/Zope-2.0.1-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: manage_propertiesForm) File /itamar/Zope-2.0.1-linux2-x86/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: propertyMap) File /itamar/Zope-2.0.1-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 321, in eval (Object: _.has_key(select_variable)) File <string>, line 0, in ?

This means you have an error in your PCGI resource file (usually Zope.cgi) or you are not pointing Zope at the right file. -Michel

Virtual Host Folder on port 80
by Mike Salib 18 Oct '99

18 Oct '99

Hi everybody, Has anyone sucessfully run Zope with the new VirtualHostFolder product from port 80? I'm seeing a really weird bug where everything works fine whe I instruct the broweser to go to http://my-virtual-host-address.com:80/ but I get an error message back when I visit http://my-virtual-host-address.com/. The error is as follows: Zope Error Zope has encountered an error while publishing this resource. Error Type: ValueError Error Value: unpack list of wrong size In addition, all images on the error page fail. I'm just wondering if anyone is running a zope system using VHFs on port 80. Any ideas anyone? Thanks a lot, Mike -- "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler

NT User Folder - No Domain support?
by Ian Blenke 18 Oct '99

18 Oct '99

After fighting with the "NT User Folder" product for quite a while, I've run across a "feature" :) Unless your NT server is a PDC/BDC for a Domain (so that the local SAM is queried), it isn't possible to use NT User Folder for authentication of users in the Domain. I'm attempting to run Zope on an IIS server that is member server in a Domain, but not a Domain Controller of any kind. The only way to limit access seems to be by adding/deleting local users and putting them in the ACL for HKLM/Software/DigitalCreations/.../Role SO, I'm entertaining alternatives. How can I reference the users in a remote Zope User Folder? It would be nice to be able to put the "smb User Folder" on a Linux server running Zope, and merely XML-RPC the folder lookups from the NT box to the Linux box. Would it be possible to create a regular acl_users folder with the preresiquite methods defined that would merely redirect the "simulated" method to another Zope server? Yes, it's a kludge. Yes it's sick and twisted. The appropriate solution would be to put the Zope server on a BDC. However, I'm not one for the "easy way out" :) - Ian C. Blenke <icblenke(a)2c2.com> <ian(a)blenke.com>

More Pystone benchmarks...
by Tony McDonald 18 Oct '99

18 Oct '99

Hi all, did some more Pystone benchmarks. As usual, with all benchmarks treat these as total fabrications... PowerMac 5400 (180 MHz 603e) running linuxppc (this is my dev box at home) = 890 iMac (266 MHz G3) MacOS 8.6 = 4800 Sun (4 x 250 MHz Ultrasparc II) running Solaris 5.6 = 2200 (lots of stuff going on) (a) Sun (1 x 350 MHz Ultrasparc IIi ) running Solaris 5.7 = 2600 (lightly loaded) (b) DELL (Pentium III 450MHz) running SUSE 6 = 5800 using Apache benchmark with a static HTML page through Apache, not Zope (page may have a couple of SSIs in it); (a) concurrency = 250, number of times = 10,000 gives 457 requests/s (b) c= 250, n = 10,000 gives 141 requests/s ie these boxes aren't slow... Q: How comes the Sun boxes are just so bad at Python? is the Sparc architecture *that* bad? weird. hth tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

The most recent release of PIL allows you to install it as a package. This fixes the name clash. Anthony -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.
