Michael Dürig commented on OAK-153:

Yet to be fixed:
* revision 1354071 removed the call to the after commit hook KernelNodeStoreBranch. See also
* revision 1354045 removed the after commit hook tests in KernelNodeStoreTest

> The {{CommitHook}} interface has two methods, {{beforeCommit()}} and {{afterCommit()}},
since the symmetry originally seemed like a good idea. However, in practice these methods
are not really so symmetric after all.
> For example, unlike {{afterCommit()}} the {{beforeCommit()}} method may end up being
called multiple times for a given changeset if it needs to be repeatedly rebased or otherwise
revised before it can be committed. There isn't even any guarantee that a particular changeset
on which {{beforeCommit()}} has been called ever gets committed. And on the other hand there
are good reasons to avoid calling {{afterCommit()}} on each and every commit that has been
made. Instead it could be called only every now and then to cover larger sets of changes.
> Thus I'd like to split the {{CommitHook}} interface to two parts that I'd tentatively
call {{CommitEditor}} and {{Observer}}.
