Evgenii Stratonikov	3cc67db083	[#1419] pilorama: Create new nodes in path if needed ... Consider a node `{FileName: "dir", Attribute: "xxx"}`. In case we add a new node by path `["dir", "file.txt"]`, create a new intermediate node with a single attribute. `GetByPath` now also considers only nodes with a single attribute while building a path.

Evgenii Stratonikov	cf73feb3f8	[#1324] local_object_storage: Implement tree service backend ... In this commit we implement algorithm for CRDT trees from https://martin.klepmann.com/papers/move-op.pdf Each tree is identified by the ID of a container it belongs to and the tree name itself. Essentially, it is a sequence of operations which should be applied in chronological order to get a usual tree representation. There are 2 backends for now: bbolt database and in-memory. In-memory backend is here for debugging and will eventually act as a memory-cache for the on-disk database. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>	2022-07-08 12:47:40 +03:00
