Re: [Zope] error-handling product?
by Dylan Reinhardt 15 Nov '02

Yes, thanks... I have quite an extensive set of DTML standard_error_message files. I've been e-mailing myself tracebacks for quite a while now. Now I want to do stuff I wouldn't use DTML for, like batch mailing and significant filtering. If nobody has heard of such a product, I guess I'll get to work making it.

Product Refresh clears Persistent attributes
by John Ziniti 15 Nov '02

15 Nov '02

This is something which has "Just Worked" for me in the past as I have developed Python Products. But now I am stumped. I have two Products. Product #1 is a: (Persistent, ObjectManager, PropertyManager, Implicit, Item) and contains other objects of type: (ObjectManager, Implicit, Item) Product #2 is a: (Persistent, RoleManager, ObjectManager, PropertyManager, Implicit, Item) which contains objects: (RoleManager, PropertyManager, Implicit, Item) The two __init__.py files are nearly identical Attributes (strings, etc.) on contained objects in Product #1 are persistent across Product refreshes, while attributes of contained objects in Product #2 are all flushed on Product reload. The only differences I can see at this point are the base classes, and the fact that Product #1 does not directly store it's sub-objects, but contains a folder which contains the objects. Should that make a difference here? What's going wrong? Thanks in advance, John Ziniti

Trouble with dtml-with
by Roger Fisher 15 Nov '02

15 Nov '02

Thanks to all the helpful replies I had for my need for a "dynamic" <dtml-with>. "_.getitem(StringOfObject)" works beautifully. I have a similar additional newbie problem: FolderA FolderB FolderC FolderD Method1 Method1 (in FolderC) has no problem, of course, doing a <dtml-with FolderD> I cannot figure out how to <dtml-with> to get from Method1 (in FolderC) to code in FolderB. FolderB is parallel to Method1's parent (FolderC). Thanks for any help.

Re: PYTHON: Searching for an object inside a folder
by ielbert 15 Nov '02

15 Nov '02

I would like to bring back the old issue because we did some tests and figured that the often-used idiom: if hasattr(myFolder.aq_explicit,object_id): #myFolder contains object_id #myFolder.aq_explicit prevents aquiring from above... does not always work as expected. It may return different result if, for example, the script is called as: otherFolder/myFolder/myFolder/script Please correct me if I am wrong but it would be better to say: if hasattr(myFolder.aq_inner.aq_explicit,object_id): #....

Python Service error
by McDonnell, Larry 15 Nov '02

15 Nov '02

Hi, I just installed Zope 2.5 on a new Windows2000 system using the Professional version. I am seeing this error which does not drop the Zope service but prevents it from running. Any suggestions? It seems to work fine if I use start.bat. The description for Event ID ( 255 ) in Source ( PythonService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: Stopping Zope..

RE: [Zope] version has tons of things locked
by Smith, Neil (Worcester) 15 Nov '02

15 Nov '02

I've had this problem recently too. I reported it to the list but nobody answered. Searching the archives I found one other person who had the same thing about six months ago. I've had it reoccur since. The only thing to do is to go through all your objects and make dummy changes to the things that are still locked to the version, then save the version again and they will then get saved. There are definitely bugs in the version stuff, but it seems to be fairly rare that it happens. I've been trying to reproduce the problem, but no luck so far. I'm using 2.4.3. What version are you on? -- Neil -----Original Message----- From: Christopher N. Deckard [mailto:chris@globalfoo.net] Sent: 13 November 2002 20:17 To: zope(a)zope.org Subject: [Zope] version has tons of things locked I was doing a bunch of changes in a version and saved the version without any problems. But now tons of things are claiming to be version locked. It seems that if I go into the version, make a change, save the version and the leave the version, that object won't be locked anymore. The problem here is that they may be about 1,000 objects that are version locked. How can I fix this? The objects that are locked should not have been locked, so if I can throw out all of the crud that's messing things up, then it should be fine. (Yes I'll make a backup of the db before I do anything.) What are my options here? At one point a new Python Script that was created in the version ended up not being able to be accessed outside of the version. I made a copy of it and then got POSkey error exceptions. I copied the contents locally, deleted the original, recreated it and pasted the old contents back into it. Everything is fine for that script now. What would have wigged out the version?

Python traceback offsets?
by Skip Montanaro 15 Nov '02

15 Nov '02

I added <dtml-var error_tb> to my standard_error_message so I could get tracebacks. Unfortunately, the information displayed isn't always enough to tell me where the error actually occurred (e.g., "AttributeError... __call__" doesn't mention any actual objects in my script), and the line numbers are off by some amount because of the missing function stuff and the boilerplate comments placed at the head of the script when I edit it via ftp. Is there some sort of fixed offset I can use to calculate the actual line number of the error in my Python script? Alternately, can I tweak the <dtml-var error_tb> stuff to get a complete traceback which includes Python source? Thx, -- Skip Montanaro - skip(a)pobox.com http://www.mojam.com/ http://www.musi-cal.com/
