Well, with STUPID_FILE_LOG (or STUPID_LOG_FILE) I managed to snag this: ------ 2000-03-10T05:03:23 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 216.32.64.10:61714 at 859ff38 channel#: 5831 requests:1> (socket.error:(32, 'Broken pipe') [/opt/Zope-2.1.4-src/ZServer/medusa/asynchat.py|handle_read|80] [/opt/Zope-2.1.4-src/ZServer/medusa/http_server.py|recv|406] [/opt/Zope-2.1.4-src/ZServer/medusa/asyncore.py|recv|256]) ------ 2000-03-10T05:03:32 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_channel connected 216.32.64.10:62068 at 8655290 channel#: 5832 requests:1> (socket.error:(32, 'Broken pipe') [/opt/Zope-2.1.4-src/ZServer/medusa/asynchat.py|handle_read|80] [/opt/Zope-2.1.4-src/ZServer/medusa/http_server.py|recv|406] [/opt/Zope-2.1.4-src/ZServer/medusa/asyncore.py|recv|256]) ------ 2000-03-10T05:04:14 INFO(0) GUF Successful authentication for user Swebb3 (http://207.241.10.50/premium/acl_users) Server is still up, but I'm wondering if these channels reopen or if they all close if that's what stops the server? I can see how this exception is getting left unhandled in the medusa code, so I'm going to try and catch it and startup the server again. -Jon Pavlos Christoforou <pavlos(a)gaaros.com> writes: > No nothing.

Zope style consider harmful
by Sin Hang Kin 10 Mar '00

10 Mar '00

Please do not try to match the start tag and end tag again and again in zope. Please come to see the http://zope.org/Members/kentsin and get the root.zexp for evaluation. This is a set of method/attributes which will publish the folder's index_htm document The methods will generate the doctype, stylesheet, javascript, rdf for the document. It can be configure by setting certain attributes. Hope this will get into the zope mainstream. Rgs, Kent Sin

Zope Stability Question
by James W. Howe 10 Mar '00

10 Mar '00

I'm working on a project for which Zope seems appropriate. However, an outside consultant for our client claims that the major problem with Zope is that it requires Python, and Python is much less stable than something like Perl. I haven't used Zope or Python enough to have counterarguments to this comment. I don't know specifically what stability issues this person may be referring to, but I would like to ask for feedback on this persons comment. Thanks. James W.

Finding crash information
by Jon Prettyman 10 Mar '00

10 Mar '00

I'm having a serious problem with my Zope server running in production. Platform: RedHat Linux 6 (2.2.12-20 kernel) Python 1.5.2 Zope 2.1.4 starting with: python z2.py as root/nobody on port 80 straight ZServer Under load (not too heavy, but busy) the Zope process SILENTLY stops. I get no traceback info anywhere that I can see. Nothing to stdout/stderr, nothing in Z2.log. If I start as: python z2.py -Z '' to prevent the fork and detach I still get no message when the crash occurs. I can't run this in DEBUG mode because I'm using GUF cookie mode to authenticate and the login screen ends up showing an exception error (by design?) If anyone can tell me how to run in DEBUG mode but make GUF still hide the exception error that would be a big help. If anyone can help me keep this server from crashing every forty-five minutes I'll buy 'em a beer next time they're in Portland. -Jon BTW, the site is very non-exotic. GenericUserFolder with a lot of static content and one ZCatalog w/CatalogAware ZClass.

Usually /lib/python/Shared/Local > > is a good place, make sure to add the > > __init__.py file inside the folder. You > > then refer to the class as Shared.Local.Chicken. -------------------------------------------------- (1) It should work. I have tested it. Nothing special is required for the __init__.py file. (2) Make sure that you have an __init__.py file inside your lib/python/Shared/Local folder. This file can be empty. Or you can provide some __doc__ and __version__ string like Digicool people do. But it really can be an empty file. (3) Inside that folder, create a file Chicken.py, which contains the following three lines: class Chicken: def __init__(self, size): self.size = size (4) This python file will not compile automatically. It will only be compiled when it is imported by some other Zope modules. (5) To test what you want: create an external method. In the folder Extensions inside your Zope root (if you don't have an Extensions folder, you have to create one first), create a file Test.py containing the following lines: import Shared.Local.Chicken def getSize(self): return self.size def test(self): Shared.Local.Chicken.Chicken.getSize = getSize a = Shared.Local.Chicken.Chicken(123) return a.getSize() (6) Go to Zope management screen. Restart Zope. (Or shut it down and restart it manually.) (7) Create an external method with 'Id' = test, 'Function name' = test, Python module file = Test and click on the 'Edit' button, then click on the 'OK' button. If you don't know what an external method is, you've got bigger problems than I thought. :) (8) Hit the 'Try It' tab. Done! now you can use the external method inside your other DTML documents/methods. For instance, you can have a mytest_dtml method with the following lines: <dtml-var standard_html_header> <dtml-var "test()"> <dtml-var standard_html_footer> and it will print the number 123 when you view it. I shouldn't have treated you like a 3-year old. But I guess making instructions as clearly as possible eliminates unnecessary confusions. :) We've all been newbies once.
