Chris Nauroth commented on HDFS-5673:
-------------------------------------
I just realized that the proposed pseudo-code for promoteDefaultEntries appears
to be mutating an access entry into a default entry. Just to clarify, the
actual requirement is not mutation, but rather copying. The access entry must
be copied to a new entry with scope set to default, but the copied access entry
must be retained without change. For this reason, I plan to keep using "copy"
in the method name instead of "promote".

> This patch will include the core logic for modification of ACLs. This
> includes support for all user-facing APIs that modify ACLs. This will cover
> access ACLs, default ACLs, automatic mask calculations, automatic inference
> of unprovided default ACL entries, and validation to prevent creation of an
> invalid ACL.
