Thank you for the response but it seems to me that my problem are not the scripts any more. Even after I deleted the scripts (simple_tree and image_batches_error) the openbsd zope refuses to import the file. After 14 minutes mozilla informed me that the connection was refused when attempting to contact the server, zope (started with -D) shows the startup messages again and nothing was imported. Importing the same file with linux-zope succeeded after 16 minutes. tia Jens-Erik

by Terry 29 Jan '02

29 Jan '02

Hello friends, I have a table1 in database. Have fieldnames like "book_id","bookname",table2 has "user_id","username" I use a Python Script call a ZSQL Method and get result from that ZSQL Method. There is not any fieldname like "phone". Why I couldn't check this in Python Script? Zope said this on my browser """ Site Error An error was encountered while publishing this resource. *Error Type: AttributeError* *Error Value: user_id* """ ###My Python Script result1 =some_ZSQL_Method_table1 result2 =some_ZSQL_Method_table2 result =[] for i in range(len(result1)): result.append(result1[i]) if len(result2) >= i+1: result.append(result2[i]) if result: for i in result: if i.user_id: print "This table have fieldname named user_id" return printed ################# Any idea ?

RE: [Zope] Auto restart (at Zope's own initiative !!!)
by Keith J. Farmer 29 Jan '02

Actually, I posted the dll and 3 test scripts (the two here, plus one non-threaded) to the sourceforge site, hoping for either a clue or a bugfix. I think I did use the extending/embedding doc you sited, along with the O'Reilly books, when I was teaching myself to write extensions. I don't recall anything much related to threading, except Py_BEGIN/END_ALLOW_THREADS, which I think just deals with blocking, which I suspect is a different (and irrelevent?) issue here. C's not my best language, so I'm always a bit suspicious of my C-code when dealing with something even remotely interesting. ---------- Keith J.

This happened on my newly installed Zope 2.5.0 (on debian box) I don't remember having done something special (just when browsing folders through the ZMI) and working alone on this server. Here is the console log... (nothing special before) 2002-01-28T20:00:31 ERROR(200) zdaemon zdaemon: Mon Jan 28 21:00:31 2002: Aiieee! 2664 exited with error code: 11 ------ 2002-01-28T20:00:31 INFO(0) zdaemon zdaemon: Mon Jan 28 21:00:31 2002: Houston, we have forked ------ (start log as usual after) Any hint ?

UnpickleableError with objects derived from Sync.Synchronized
by Alexei Ustyuzhaninov 29 Jan '02

29 Jan '02

Hi! I have objects in my product which shouldn't be accessed simultaneously by different threads. So I mixed their class in the Sync.Synchronized class as recommended in http://www.zope.org/Documentation/How-To/ThreadSafety. But now I can't even create the objects because of UnpickleableError: Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 175, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 240, in commit File /usr/lib/zope/lib/python/ZODB/Transaction.py, line 302, in commit File /usr/lib/zope/lib/python/ZODB/Connection.py, line 418, in commit (Info: (('Products.Tap3Editor.tap3editor', 'tap3editor'), '\x00\x00\x00\x00\x00\x00j\x08', '')) UnpickleableError: (see above) I use zope 2.4.2 for linux from debian binary distribution. So could someone explain what's the problem here? -- Best regards, Alexei

As a counter-case; I had a bunch of these and they would _not_ run until they were recompiled. Most annoying. There's a magic method that does a find-and-apply to all python scripts automatically, can't remember what it's called off the top of my head.

Folder view error in ZMI
by Schmidt, Allen J. 29 Jan '02

Just started getting an odd error on a folder. The folder contains lots of relatively small images; hundreds. The images continue to be displayed correctly when called individually. When clicking on the folder I am getting this error (on the page) and traceback (viewing the source): Error Type: KeyError Error Value: § ---------------------------------------------------------------------------- ---- Troubleshooting Suggestions This resource may be trying to reference a nonexistent object or variable §.

Simple (I hope) question re: images
by Angie Bayley 29 Jan '02

29 Jan '02

Hi all, I have what I suspect is a very simple question regarding images, but I've had a look through the list archives and also through the Zope book and can't track down an answer. This is a site which is being virtually hosted; Apache and Zope both running on the same box and Apache rewriting URLs to pass them to Zope. I want to keep images in a folder of their own on a Zope site that I am creating - not too unusual - and currently I'm referencing them from other folders as dtml-var "images.example_gif" (angle brackets removed to avoid confusing mail programs, browsers etc.) This gives me the right image, but the source code produced is wrong; it gives http://host.with.zope:8080/virtual.host.name/images/example.gif whereas what I'd rather have it produce would be /images/example.gif or, at a pinch, http://virtual.host.name/images/example.gif Am I missing something blatantly obvious here, or can someone suggest a workaround for this? Thanks Angie _________________________________________________________________ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com
