Netscape has a menu item "view image" in the context menu for images. Alternatively, you can directly open the image's URL. Opening the image alone gives you more information about the problem: you prabably will get a standard Zope error page with problem description and traceback. Maybe, you encountered some of the image problems that have been discussed in Zope or Zope-dev about 2 weeks ago. Dieter

PCGI application Question?
by kwan 15 Jun '00

15 Jun '00

Hi: In the way of PCGI work. PCGI Wrapper sends request to PCGI Application throught INET port. This is what mention on ZAG document. However, it also has a note said that the PCGI Wrapper is capable of launching the PCGI application, if it is not currently running My problem is, how to found out that the PCGI application is not running and which cause the PCGI Wrapper to launch it instead? My situation is like this: I setup Zope communicate with IIS. However, after I use the scripts/zope.pcgi the var/pcgi.pid got changed. As the ZAG document mention above, it looks like after the Zope server startup... somehow, the PCGI Application (is it pcgi_publisher.py?) dead/shutdown. Which makes PCGI Wrapper (pcgi-wrapper.exe?) to launch its own one. Hence, a new proccess with different PID. Since it is a different proccess, it is not allow to touch the Database file and cause me get the error message "Could not lock the database file" Am I right on this? If this is the situation, how do I check to make sure the PCGI Application actually dead or not response after Zope start up? What can I do to check what cause it to close? Thanks very much for your time Kwan

problem with PTK and LoginManager
by Tim Lynch 15 Jun '00

15 Jun '00

Hi, I can't seem to get PTK to install. When I put both PTKBase and PTKDemo in the Products directory, PTKBase is OK, but PTKDemo is 'broken'. The traceback is: Traceback (innermost last): File "E:\I-10\lib\python\OFS\Application.py", line 387, in import_products product=__import__(pname, global_dict, global_dict, silly) File "E:\I-10\lib\python\Products\PTKDemo\__init__.py", line 3, in ? import Portal, ZODBMember, SQLMember, PersistentUserSource File "E:\I-10\lib\python\Products\PTKDemo\Portal.py", line 5, in ? from Products import LoginManager ImportError: No module named LoginManager LoginManager is installed in Products and is listed as OK in the Control Panel/Products display. I just did a complete re-install of Zope 2.1.4 (no other products at this time); I grabbed PTK from the CVS tree, the version of LoginManager I'm using is what came with the PTK. I'm running under WindowsNT with zope installed as a service. Haven't tried things on the Linux side of my machine as I need to get this stuff working under NT as a deliverable. Any ideas why Portal.py can't find LoginManager? I've tried editing the line in Portal.py from from Products import LoginManager to from Products.LoginManager import LoginManager but that didn't seem to work Any help much appreciated.

Living dangerously - lost objects re-appear after database packing
by Paul Browning 15 Jun '00

15 Jun '00

Hi - I don't recall any mention of this sort of experience before so I thought I'd share it and would be interested in reactions. Yesterday around 18:30 (BST) two Linux boxes of mine which both run Zope re-booted - as they sit next to each other on the same electrical supply I've assuming there was some sort of spike. Neither are setup to re-start Zope services automatically - these are not production servers. They are also not backed up .... So I did the usual manual restart and, on one, got a bit of a shock. It went like this: 1. Login to box running RH 5.2 2. su 3. Start Zope 2.1.6 that has been running fine for months. 4. Open browser to check most recent stuff that I've developed looks OK - it's not there. 5. Go to management screen - newer folders are missing. 6. Go to Undo. Most recent transaction Apr 19. Uh-oh. 7. Decide to get out quick. Shutdown via CP. 8. Data.fs shown as last modified 6 June. 9. Copied Data.fs (having no regular back-ups) 10. Restarted Zope 11. Packed database (shrinks from 36MB to 9MB). 12. Breathe sigh of relief as missing folders re-appear. Is this normal, doctor?

getUsers cf. get_valid_userids question
by Geoff Gardiner 15 Jun '00

15 Jun '00

I want to show all users who have certain roles / and or permissions (Zope 2.1.6). I can't see how to do this directly, because I can't see how to get hold of user objects, which I need to carry out has_permission, etc., methods. I can show the userids of all valid users: <dtml-in get_valid_userids> <dtml-let uid=sequence-item> <dtml-var uid><br> </dtml-let> </dtml-in> but I can't get all actual user objects because getUsers is a method valid only for an identified User folder, and doesn't have acquisition. Should I just go in and code a new get_valid_users in the style of get_valid_userids, or is there another way? Perhaps there would be a security implication (I can't think what) but that's not a major issue for me at the moment. Thank you, Geoff

Hi all, I'm trying to create a product with a Z Class (call it Z_Super) that contains other (private) Z Classes (call them Z_Subs). Creating Z_Super is no problem, but creating Z_Sub in Z_Super gives me the following traceback: Traceback (innermost last): File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: RoleManager) File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 151, in publish File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/BaseRequest.py, line 430, in traverse File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/AccessControl/User.py, line 375, in validate (Object: RoleManager) File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/HTTPResponse.py, line 511, in notFoundError NotFound: (see above) FYI I'm using Zope 2.1.6.

Re: [Zope] Virtual hosts: How to make proper intra-site URL's?

So far so good. >I have not been able to produce this effect using either BASE0..N or >URL0..N. > >Help? You probably need the SiteAccess product by Evan Simpson to do this. It is at http://www.zope.org/Members/4am/SiteAccess . I don't use it myself, but apparently many people on the list do. I don't know if it's already safe to use it with 2.2 beta, but for a production site you probably won't run this anyway Rik
