Please file a feature request to "".
Zope should distinguish between "Write" and "Read conflict errors".
You can try the necessary modification yourself. Patch
for Zope 2.6.1 attached.

You probably see a "Database read conflict error".
It may happen for reading "foo", "bar" or "tab_kopf".
The patch will give you hints what object got this error.

You may look at my "pydoc" patches.
Maybe, something similar allows you to use "epydoc", too.

[Zope-dev] Call Product Constructor

2003-03-28 Thread Matt Ficken 
This is the __init__.py of my product (ZID):

from ZIDProduct import ZID

def initialize ( context ):
  context.registerClass(
ZID,
constructors = (
  ZID.manage_addZIDForm,
  ZID.manage_addZID,
  ZID.manage_add_folder
)
  )

I want the constructor ZID.manage_add_folder to get called at the end of the 
initialize function. How do I do this?

Conflict Errors are things that can happen during the normal course of a
Zope operation. They happen whenever a request tries to read or write an
object for the first time in a request (transaction) that started before
another request (transaction) that already modified such object. Zope
automatically restarts the conflicting transaction, so the only visible
effect is a little delay before the transaction finishes.

You should only worry if you're seeing a copious amount of such
messages, or if you are seeing these errors in the browser, which
happens after zope retries the transaction 3 times and still gets a
conflict error, in which case it gives up.

Cheers, Leo

[Zope-dev] ConflictError

2003-03-28 Thread Andre Schubert 
Hi all,

i have a little problem with the following log-entry in my logfile.

2003-03-28T10:09:18 INFO(0) ZODB conflict error at /foo/bar/tab_kopf (1 conflicts 
since startup at 2003-03-28T10:09:03).

After searching through several mailinglists i found that this
error seem to occur when using sessions, i'am right ?
But my problem is, that tab_kopf is a ImageFile defined in my Product.

tab_kopf = ImageFile('www/tab_kopf.gif',globals())

I dont understand how there could be a ConflictError on a Image ?
I hope someone could give me a tip whats going on.

Thanks in advance, as

How can I make a fixure to get it working ? Did any of you succeed
documenting Zope products with epydoc ?
Two weeks ago I wrote a patch for the cvs version of epydoc that works 
with Zope 2 ExtensionClasses. It's not released because there are still 
some bugs, but if you like I could send you the patch.

Cheers,

Yuppie
