The two steps so far seems to give the necessary information to code
paths that want them, so it is not wrong per-se, but this makes me
wonder a few things.
- There may be multiple ref backends and iterators corresponding to
them. Is it reasonable to assume that there are backends that do
not need "repo"? Otherwise, shouldn't this be added to the base
class "struct ref_iterator base"?
- The iterator_begin() and other functions have been taught to take
the repository in addition to the ref_store in the previous step,
but
. Doesn't iterator iterate over a single ref_store? Shouldn't it
have a pointer to the ref_store it is iterating over?
. Doesn't a ref_store belong to a single repository? Shouldn't
it have a pointer to the repository it is part of?
If the answers to both are 'yes', then we wouldn't need to add a
repository pointer as a new parameter to functions that already
took a ref store.
In other words, I am wondering if the right pieces of information
are stored in the right structure.
Thanks.
