Wouldn't it be better to just move IPubFailure before the abort? Is there a reason for subscribing to such an event which would required the transaction to be aborted already? I can see the usefulness of the transaction being already doom()ed before this event, but not aborted. On Wed, Nov 11, 2009 at 08:53, Martin Aspeli <optilude+lists@gmail.com> wrote:
Hi,
In Zope 2.12 ZPublisher we have a good set of events now, which provide useful hooks for modifying the response before or after publication. However, I'd like to add one more. ;-)
Basically, we have IPubFailure, but this is sent *after* transaction.abort() and endInteraction(). This means that it's impossible to read from the ZODB when trying to deal with a failure.
I'd like to add an event before that, IPubBeforeAbort, which mirrors IPubBeforeCommit in being sent before the transaction is aborted.
I can do this on Zope trunk + 2.12 branch if no-one objects.
