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.

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.

Zope Question : Virtual folders / URL's
by Ian Sparks 10 Mar '00

10 Mar '00

Have been reading the docs but still not clear on a few things. I have my site mapped out in my mind. It has URL's like : mysite.com/ (main page) mysite.com/rss (rss content for mysite) mysite.com/<username> (main <username> page) mysite.com/<username>/rss (rss news content feed for <username> page) Where I come from data belongs in a database. I'm happy for all my HTML to be in the ZopeDB but not any application data (users definitions, news items etc etc). So, looking at my URLs I see that there are a mixture of static and virtual folders. mysite.com/index_html is obviously static though it contains dynamic content. Doing this with Zope is easy and obvious. mysite.com/Fred/ is a dynamic page. Fred only exists as a username in a users table and related information in other tables. It's not obvious to me how I go about serving this page because I can't create a static page for every username (nor do I want to). Clearly mysite.com/Fred/rss will use almost identical processing to the mysite.com/rss page, just different parameters so re-using my "rss" generating code is important to me too. I'm know these virtual folders can be served up by Zope. Can someone tell me what I am missing? - Ian Sparks.

how do you do dynamic redirection?
by Graham Chiu 10 Mar '00

10 Mar '00

I would like to redirect a user based upon a variable. <dtml-call "RESPONSE.redirect(/target?myvariable=xyz)"> raises a syntax error. Does the redirect command only take literals? ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin

No resposne to valid HTTP requests.
by Curtis Maloney 10 Mar '00

10 Mar '00

Greetings, So, I got into work this morning, ready for another day of zoping, only to find my server not quite responding properly. When i went to the manage screen, the tree frame didn't fill, but the right-hand frame was fine. Hmm, thought I. Oh well... i can work without it. So, I clicked on the folder for todays work and..... nothing.... no response at all, not ever a timeout! Talk to the network admin, we both kick about... and it seems that the ZOPE server will respond correctly to invalid GET requests, but just freeze on valid requests. Further testing shows that it's ONLY when i try to use the management screens. The only change in my system recently has been upgrading from NS4.7 to NS4.72. It's RedHat 6.1, and Zope 2.1.4. Any idea? -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>
