To address the problem demonstrated in #1282, clean needs to delete things in a top-level order, and skip cleaning children of anything deemed uncleanable. The plan is to make iter_objects (now iter_items) return more detailed information including what the item's parent(s) are, so that the consumer of the stream can build up a graph of items. Since iter_items can be called over RPC and used as a stream, it isn't practical to compute the entire graph and return it in a single response. But the stream items can be used to build up the graph incrementally. Signed-off-by: J Robert Ray <jrray@jrray.org>
This is only true when there are no concurrent writers! This is the test from #1282 but passes as of the changes in this PR. Signed-off-by: J Robert Ray <jrray@jrray.org>

There was a problem hiding this comment.
Note to self, this should also mark these objects as attached in self.attached.

It's working as a proof of concept (as in all tests pass) but I didn't update the rpc repo type for these changes
and handling payloads is unfinished. I'm surprised it even compiles with the server feature enabled, as I was avoiding turning that feature on until I got the basics working.Edit: I see, object iteration over rpc isn't supported.
