I am trying to trap the following
error:
Traceback (innermost last):
Module Zope2.App.startup, line 173, in zpublisher_exception_hook Module ZPublisher.Publish, line 121, in publish Module Zope2.App.startup, line 240, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 380, in commit Module transaction._transaction, line 378, in commit Module transaction._transaction, line 433, in _commitResources Module ZODB.Connection, line 484, in commit Module ZODB.Connection, line 526, in _commit Module ZODB.Connection, line 554, in _store_objects Module tempstorage.TemporaryStorage, line 200, in store ConflictError: database conflict error (oid 0x39b0, class BTrees._OOBTree.OOBucket, serial this txn started with 0x0366974da4fd2288 2006-07-04 13:33:38.669252, serial currently committed 0x0366974da54d9fcc 2006-07-04 13:33:38.742942) in an external method, as follows:
folder =
self.unrestrictedTraverse(TEMPFOLDERIMAGES,
None)
try: folder.manage_addImage(imageId, imageData)
except:
<handle error message and return gracefully code> But the try/except block is not catching the error!
(the error continues to show up in error_log)
(note: I started by trying "except ConflictError:",
but that was not working, so I went to the bare try/except)
The traceback does not show where the
error originates in the external method, but there is only one place
where the external methods writes to TemporaryStorage. Does this indicate
that the error is not bubbling up properly? Any ideas as to why the error trapping is not
trapping? (running Zope 2.9.2, debug=on)
Thanks,
Jonathan
