* Normalised storage tree addressing in function prototypes
detail:
Argument list is always `<db> <account-path> <slot-path> ..` with
both path arguments as `openArray[]`
* Remove cruft
* CoreDb internally Use full account paths rather than addresses
* Update API logging
* Use hashed account address only in prototypes
why:
This avoids unnecessary repeated hashing of the same account address.
The burden of doing that is upon the application. In the case here,
the ledger caches all kinds of stuff anyway so it is common sense to
exploit that for account address hashes.
caveat:
Using `openArray[byte]` argument types for hashed accounts is inherently
fragile. In non-release mode, a length verification `doAssert` is
enabled by default.
* No accPath in data record (use `AristoAccount` as `CoreDbAccount`)
* Remove now unused `eAddr` field from ledger `AccountRef` type
why:
Is duplicate of lookup key
* Avoid merging the account record/statement in the ledger twice.
* CoreDb: remove PHK tries
why:
There is no general use anymore for an MPT with a pre-hashed key. It
was used to resemble the `SecureHexaryTrie` logic from the legacy DB.
The only pace where this is needed is the `Leger` which uses a
a distinct MPT version anyway (see `distinct_ledgers.nim`.)
* Rename `CoreDx*` -> `CoreDb*`
why:
The naming `CoreDx*` was used to differentiate the new CoreDb API from
the legacy API which had descriptors named `CoreDb*`.
* Fix initialiser
why:
Possible crash (app profiling, tracer etc.)
* Update column family options processing
why:
Same for kvt as for aristo
* Move `AristoDbDualRocks` backend type to the test suite
why:
So it is not available for production
* Fix typos in API jump table
why:
Used for tracing and app profiling only. Needed some update
* Purged CoreDb legacy API
why:
Not needed anymore, was transitionary and disabled.
* Rename `flush` argument to `eradicate` in a DB close context
why:
The word `eradicate` leaves no doubt what is meant
* Rename `stoFlush()` -> `stoDelete()`
* Rename `core_apps_newapi` -> `core_apps` (not so new anymore)
* Code cosmetics
* Aristo+Kvt: Fix api wrappers
why:
Api setup killed the backend descriptor when backend mapping was
disabled.
* Aristo: Implement masked profiling entries
why:
Database backend should be listed but not counted in tally
* CoreDb: Simplify backend() methods
why:
DBMS backend access Was provided very early and over engineered. Now
there are only two backend machines, one for `Kvt` and the other one
for an `Mpt` available only via new API.
* CoreDb: Code cleanup regarding descriptor types
* CoreDb: Refactor/redefine `persistent()` methods
why:
There were `persistent()` methods for any type of caching storage
facilities `Kvt`, `Mpt`, `Phk`, and `Acc`. Now there is only a single
`persistent()` method storing all facilities in tandem (similar to
how transactions work.)
For non shared `Kvt` tables, there is now an extra storage method
`saveOffSite()`.
* CoreDb lingo update: `trie` becomes `column`
why:
Notion of a `trie` is pretty much hidden by the new `CoreDb` api.
Revealed are sort of database columns for accounts an storage data,
any of which have an internal state represented by a Keccack hash.
So a `trie` or `MPT` becomes a `column` and a `rootHash` becomes a
column state.
* Aristo: rename backend filed `filters` => `journal`
* Update full sync logging
details:
+ Disable eth handler noise while syncing
+ Log journal depth (if available)
* Fix copyright year
* Fix cruft and unwanted imports
* CoreDb+Ledger: Update logging
why:
Use symbol `api` rather than `ctx` because the latter will be used
as name for particular objects
* CoreDb: Remove cruft
* CoreDb: Remove `TxID` support
why:
It is nowhere used and ugly implemented. The upcoming context layer
will be a cleaner alternative to use, instead should this particular
functionality be needed.
* CoreDb: Rearrange base methods in source code for better reading
* CoreDb+Aristo: Update API closures for better reading & maintenance
* CoreDb: Implement context layer for MPT
why:
On `Aristo` the context layer allows to manage different views on
the same backend database. This is an abstraction of the legacy
hexary trie which can be localised on a particular root nose.
details:
The `ctx` context provides the state (equiv. to state root) of the
database for MPT and account descriptors.
* Fix Copyright headers
