Kris Nuttycombe 9a77e51cc4 shardtree: Rework rewind & checkpoint depth handling. 2024-09-27 08:44:14 -06:00
Kris Nuttycombe 05f23d9763 incrementalmerkletree-testing: Always rewind to a checkpoint. 
The previous semantics of the `rewind` operation would remove the last
checkpoint, if any, but would not further modify the tree. However,
these semantics are error prone - if you rewind to a checkpoint, you are
not able to rewind to the same checkpoint again; also, in practice, it
doesn't make sense to shift the location of a checkpoint in the note
commitment tree. This change alters `rewind` to (a) take an explicit
checkpoint depth, with depth `0` meaning that any state added since the
last checkpoint should be discarded, and (b) only allow a rewind
operation to succeed if a checkpoint actually exists at the specified
depth.

Merge pull request #114 from nuttycom/bridgetree-0.6.0 
Release `bridgetree` version 0.6.0.
 2024-09-25 16:51:29 -06:00
Kris Nuttycombe 13a52fcea4 Release `bridgetree` version 0.6.0. 
This change removes `bridgetree` from the workspace, so that it will no
longer be maintained in lockstep with changes to the
`incrementalmerkletree` crate. `bridgetree` will only receive bug-fix
changes in the future.

Kris Nuttycombe 192cb3ffda shardtree: Remove `Node::Pruned` 
In 7e48886fd3, `Node::Pruned` was
introduced in order to fix problems with `LocatedTree::max_position`
resulting from reinsertion of subtree information as children of
a previously pruned subtree represented by a `Node::Leaf` at its
root. This fix introduced a large amount of complexity that is
better resolved by fixing the `max_position` function in a different
way and generally minimizing its usage.

This makes it easier for us to track where new tree nodes are created,
and how the node kinds are used within the `ShardTree` data model.

incrementalmerkletree: Documentation fix for `Checkpoint` retention.

Kris Nuttycombe d40e178f8d shardtree: Do not unify pruned nodes with empty nodes. 2024-05-28 19:22:45 -06:00
Kris Nuttycombe 7e48886fd3 shardtree: Add `Pruned` node type 
In circumstances where insertion into a subtree results in pruning, and
then a subsequent insertion within the same range contains leaves that
must be retained, it is necessary to be able to distinguish the maximum
position among notes that have been observed but later pruned. This
fixes a bug wherein an insertion into an already-pruned tree could cause
the maximum position reported for the subtree to regress.
 2024-05-28 19:22:45 -06:00
Kris Nuttycombe ffc087424d shardtree: Discard `REFERENCE` retention in leaf overwrites. 
Also, disallow value-conflicted overwrites at the leaf level.

Kris Nuttycombe e55ff2d7f2 incrementalmerkletree: add `Reference` retention type. 
This new retention type is intended to be used when inserting frontiers
that should not automatically be pruned.

Also, improve documentation for the `Retention` type.
