I do not think it is such a good idea to allow API callers to
specify for-each-ref-fn directly. See my message in an earlier
review.
I also think ref_filter_cbdata is an implementation detail of
filter_refs and may not have to be exposed to the API callers.
It probably is more sensible for them to pass
- an array of refs to receive filtered results (your ref_array thing)
- the criteria to use when filtering (your ref_filter thing)
as two separate parameters to this function, together with other
parameters that lets you (meaning the implementation of filter_refs())
to decide which for-each-ref iterator to call, e.g. do you want to
use raw iteration? do you want to iterate only over refs/heads? etc.
In other words, the caller of this API should not have to know that
you (meaning the implementation of filter_refs()) are internally
using for_each_ref() API.
