[Zope-dev] post publishing hook

[Florent Guillaume]

I really could use a post publishing hook.
Standard use case: delay indexing at the end of the request to only do 
it once per object even if the object has been modified 4 times.

Today there's the REQUEST._hold() hack with an instance having a 
__del__, but this gets executed outside the main transaction, and 
REQUEST is already dying.

I'd like a post-publishing hook that's called in the initial REQUEST and 
transaction.

Open issues are:
1. what if there's an exception in the hook? I'd say log it but that's all.
2. what if there's a Conflicterror? That's tougher to deal with... The 
transaction has to be retried, without the user being aware of it, so it 
means the hook should probably be called *before* things are sent to the 
browser.

What do you think?
