Subject: cloning a namespace downloads all the objects
Message-ID: <CAMK1S_hdsgXoPcSn__htpGCpmCsAGb9j+m+SvxtO_69eqC92gA@mail.gmail.com>

Hi,

I have a repo on a server, which contains, as namespaces, the contents
of several different repos of varying sizes.  When I run a clone
command for the smallest of the namespaces (I have a script that
intercepts the clone and sets GIT_NAMESPACE appropriately), I get the
correct set of refs, but *all* the objects from *all* the namespaces.

And since no refs from the other namespaces have come down, a 'git gc
--prune=now', run immediately after, reduces the size of
".git/objects" to the size I would expect for just that small
namespace.

In effect, it is bringing down data that is not reachable and will be
wiped out on the next gc.

Is this expected?
