Core db update storage root management for sub tries (#1964) * Aristo: Re-phrase `LayerDelta` and `LayerFinal` as object references why: Avoids copying in some cases * Fix copyright header * Aristo: Verify `leafTie.root` function argument for `merge()` proc why: Zero root will lead to inconsistent DB entry * Aristo: Update failure condition for hash labels compiler `hashify()` why: Node need not be rejected as long as links are on the schedule. In that case, `redo[]` is to become `wff.base[]` at a later stage. This amends an earlier fix, part of #1952 by also testing against the target nodes of the `wff.base[]` sets. * Aristo: Add storage root glue record to `hashify()` schedule why: An account leaf node might refer to a non-resolvable storage root ID. Storage root node chains will end up at the storage root. So the link `storage-root->account-leaf` needs an extra item in the schedule. * Aristo: fix error code returned by `fetchPayload()` details: Final error code is implied by the error code form the `hikeUp()` function. * CoreDb: Discard `createOk` argument in API `getRoot()` function why: Not needed for the legacy DB. For the `Arsto` DB, a lazy approach is implemented where a stprage root node is created on-the-fly. * CoreDb: Prevent `$$` logging in some cases why: Logging the function `$$` is not useful when it is used for internal use, i.e. retrieving an an error text for logging. * CoreDb: Add `tryHashFn()` to API for pretty printing why: Pretty printing must not change the hashification status for the `Aristo` DB. So there is an independent API wrapper for getting the node hash which never updated the hashes. * CoreDb: Discard `update` argument in API `hash()` function why: When calling the API function `hash()`, the latest state is always wanted. For a version that uses the current state as-is without checking, the function `tryHash()` was added to the backend. * CoreDb: Update opaque vertex ID objects for the `Aristo` backend why: For `Aristo`, vID objects encapsulate a numeric `VertexID` referencing a vertex (rather than a node hash as used on the legacy backend.) For storage sub-tries, there might be no initial vertex known when the descriptor is created. So opaque vertex ID objects are supported without a valid `VertexID` which will be initalised on-the-fly when the first item is merged. * CoreDb: Add pretty printer for opaque vertex ID objects * Cosmetics, printing profiling data * CoreDb: Fix segfault in `Aristo` backend when creating MPT descriptor why: Missing initialisation error * CoreDb: Allow MPT to inherit shared context on `Aristo` backend why: Creates descriptors with different storage roots for the same shared `Aristo` DB descriptor. * Cosmetics, update diagnostic message items for `Aristo` backend * Fix Copyright year

This feature needed an abstraction of the `HashKey` object which is now either a hash or a blob of length at most 31 bytes. This leaves two ways of representing an empty/void `HashKey` type, either as an empty blob of zero length, or the hash of an empty blob. * Update `CoreDb` interface (mainly reducing logger noise) * Fix copyright years (to make `Lint` happy)

Core db and aristo maintenance update (#2014) * Aristo: Update error return code why: Failing of `Aristo` function `delete()` might fail because there is no such data item on the db. This must return a single error code as is done with `fetch()`. * Ledger: Better error handling why: The `expect()` clauses have been replaced by raising asserts indicating the error from the database backend. Also, `delete()` failures are legitimate if the item to delete does not exist. * Aristo: Delete function must always leave a label on DB for `hashify()` why: The `hashify()` uses the labels left bu `merge()` and `delete()` to compile (and optimise) a scheduler for subsequent hashing. Originally, the labels were not used for deleted entries and `delete()` still had some edge case where the deletion label was not properly handled. * Aristo: Update `hashify()` scheduler, remove buggy optimisation why: Was left over from version without virtual state roots which did not know about account payload leaf vertices referring to storage roots. * Aristo: Label storage trie account in `delete()` similar to `merge()` details; The `delete()` function applied to a non-static state root (assumed to be a storage root) will check the payload of an accounts leaf and mark its Merkle keys to be re-checked when runninh `hashify()` * Aristo: Clean up and re-org recycled vertex IDs in `hashify()` why: Re-organising the recycled vertex IDs list intends to reduce the size of the list. This list is organised as a LIFO (or stack.) By reorganising it in a way so that the least vertex ID numbers are on top, the list will be kept smaller as observed on some examples (less than 30%.) * CoreDb: Accept storage trie deletion requests in non-initialised state why: Due to lazy initialisation, the root vertex ID might not yet exist. So the `Aristo` database handlers would reject this call with an error and this condition needs to be handled by the API (which realises the lazy feature.) * Cosmetics & code massage, prettify logging * fix missing import

Core db aristo hasher profiling and timing improvement (#1938) * Explicitly use shared `Kvt` table on `Ledger` and `Clique` lookup. why: Speeds up lookup time with `Aristo` backend. For writing `Clique` data, the `Companion` model allows to write `Clique` data past the database locked by evm transactions. * Implement `CoreDb` profiling with API tracking why: Chasing time spent per APT procs ... * Implement `Ledger` profiling with API tracking why: Chasing time spent per APT procs ... * Always hashify when commiting or storing why: A dirty cache makes no sense when committing * Make sure that a zero key is created when adding/updating vertices why: This is an error fix mainly for edge cases. A typical error was that the root key got deleted when there were only a few vertices left on the DB. * Need all created and changed vertices zero-keyed on the cache why: A zero key (i.e. empty Merkle hash) indicates that a vertex key needs to be updated. This would not be needed immediately after a merge as there is an actual leaf path on the cache layer. But after subsequent merge and delete operations this information might get blurred. * Re-org hashing algorithm why: Apart from errors, the previous implementation was too slow for two reasons: + some control hashes were calculated for debugging (now all verification is done in `aristo_check` module) + the leaf paths stored on the cache are used to build the labelling (aka hashing) schedule; there paths were accumulated over successive hash sessions although it is clear that all keys were generated, already

Aristo db update for short nodes key edge cases (#1887) * Aristo: Provide key-value list signature calculator detail: Simple wrappers around `Aristo` core functionality * Update new API for `CoreDb` details: + Renamed new API functions `contains()` => `hasKey()` or `hasPath()` which disables the `in` operator on non-boolean `contains()` functions + The functions `get()` and `fetch()` always return a not-found error if there is no item, available. The new functions `getOrEmpty()` and `mergeOrEmpty()` return an an empty `Blob` if there is no such key found. * Rewrite `core_apps.nim` using new API from `CoreDb` * Use `Aristo` functionality for calculating Merkle signatures details: For debugging, the `VerifyAristoForMerkleRootCalc` can be set so that `Aristo` results will be verified against the legacy versions. * Provide general interface for Merkle signing key-value tables details: Export `Aristo` wrappers * Activate `CoreDb` tests why: Now, API seems to be stable enough for general tests. * Update `toHex()` usage why: Byteutils' `toHex()` is superior to `toSeq.mapIt(it.toHex(2)).join` * Split `aristo_transcode` => `aristo_serialise` + `aristo_blobify` why: + Different modules for different purposes + `aristo_serialise`: RLP encoding/decoding + `aristo_blobify`: Aristo database encoding/decoding * Compacted representation of small nodes' links instead of Keccak hashes why: Ethereum MPTs use Keccak hashes as node links if the size of an RLP encoded node is at least 32 bytes. Otherwise, the RLP encoded node value is used as a pseudo node link (rather than a hash.) Such a node is nor stored on key-value database. Rather the RLP encoded node value is stored instead of a lode link in a parent node instead. Only for the root hash, the top level node is always referred to by the hash. This feature needed an abstraction of the `HashKey` object which is now either a hash or a blob of length at most 31 bytes. This leaves two ways of representing an empty/void `HashKey` type, either as an empty blob of zero length, or the hash of an empty blob. * Update `CoreDb` interface (mainly reducing logger noise) * Fix copyright years (to make `Lint` happy)

Core db update providing additional results code interface (#1776) * Split `core_db/base.nim` into several sources * Rename `core_db/legacy.nim` => `core_db/legacy_db.nim` * Update `CoreDb` API, dual methods returning `Result[]` or plain value detail: Plain value methods implemet the legacy API, they defect on error results * Redesign `CoreDB` direct backend access why: Made the `backend` directive integral part of the API * Discontinue providing unused or otherwise available functions details: + setTransactionID() removed, not used and not easily replicable in Aristo + maybeGet() removed, available via direct backend access + newPhk() removed, never used & was experimental anyway * Update/reorg backend API why: + Added error print function `$$()` + General descriptor completion (and optional validation) via `bless()` * Update `Aristo`/`Kvt` exception handling why: Avoid `CatchableError` exceptions, rather pass them as error code where appropriate. * More `CoreDB` compliant `Aristo` and `Kvt` methods details: + Providing functions like `contains()`, `getVtxRc()` (returns `Result[]`). + Additional error code: `NotImplemented` * Rewrite/reorg of Aristo DB constructor why: Previously used global object `DefaultQidLayoutRef` as default initialiser. This object was created at compile time which lead to non-gc safe functions. * Update nimbus/db/core_db/legacy_db.nim Co-authored-by: Kim De Mey <kim.demey@gmail.com> * Update nimbus/db/aristo/aristo_transcode.nim Co-authored-by: Kim De Mey <kim.demey@gmail.com> * Update nimbus/db/core_db/legacy_db.nim Co-authored-by: Kim De Mey <kim.demey@gmail.com> --------- Co-authored-by: Kim De Mey <kim.demey@gmail.com>
