Abstract view over block header storage. This module aims to abstract over block header's read, read_opt and known functions by calling the adequate function depending on the block being pruned or not.

val known : Chain.t -> Tezos_crypto.Block_hash.t -> bool Lwt.t
val known_valid : Chain.t -> Tezos_crypto.Block_hash.t -> bool Lwt.t
val known_invalid : Chain.t -> Tezos_crypto.Block_hash.t -> bool Lwt.t
val list_invalid : Chain.t -> (Tezos_crypto.Block_hash.t * int32 * Tezos_error_monad.TzCore.error list) list Lwt.t
val read_contents_opt : t -> Legacy_store.Block.contents option Lwt.t
val read_opt : Chain.t -> Tezos_crypto.Block_hash.t -> t option Lwt.t
val read_predecessor : Chain.t -> pred:int -> Tezos_crypto.Block_hash.t -> t option Lwt.t

Will return the full block if the block has never been cleaned (all blocks for nodes whose history-mode is set to archive), only the header for nodes below the save point (nodes in full or rolling history-mode). Will fail with `Not_found` if the given hash is unknown.

val remove : t -> (unit, Tezos_error_monad.TzCore.error list) result Lwt.t

remove block deletes every occurrence of block in the different stores. If block is the current head, the head is also backtracked to the block predecessor

known_ancestor chain_state locator computes the unknown prefix in the locator according to chain_state. It either returns:

  • Some (h, hist) when we find a valid block, where hist is the unknown prefix, ending with the first valid block found.
  • Some (h, hist) when we don't find any block known valid nor invalid and the node runs in full or rolling mode. In this case (h, hist) is the given locator.
  • None when the node runs in archive history mode and we find an invalid block or no valid block in the locator.
  • None when the node runs in full or rolling mode and we find an invalid block in the locator.
