* ForkedChain implementation
- revamp test_blockchain_json using ForkedChain
- re-enable previously failing test cases.
* Remove excess error handling
* Avoid reloading parent header
* Do not force base update
* Write baggage to database
* Add findActiveChain to finalizedSegment
* Create new stagingTx in addBlock
* Check last stateRoot existence in test_blockchain_json
* Resolve rebase conflict
* More precise nomenclature for block import cursor
* Ensure bad block nor imported and good block not rejected
* finalizeSegment become forkChoice and align with engine API forkChoice spec
* Display reason when good block rejected
* Fix comments
* Put BaseDistance into CalculateNewBase equation
* Separate finalizedHash from baseHash
* Add more doAssert constraint
* Add push raises: []
* Disable `TransactionID` related functions from `state_db.nim`
why:
Functions `getCommittedStorage()` and `updateOriginalRoot()` from
the `state_db` module are nowhere used. The emulation of a legacy
`TransactionID` type functionality is administratively expensive to
provide by `Aristo` (the legacy DB version is only partially
implemented, anyway).
As there is no other place where `TransactionID`s are used, they will
not be provided by the `Aristo` variant of the `CoreDb`. For the
legacy DB API, nothing will change.
* Fix copyright headers in source code
* Get rid of compiler warning
* Update Aristo code, remove unused `merge()` variant, export `hashify()`
why:
Adapt to upcoming `CoreDb` wrapper
* Remove synced tx feature from `Aristo`
why:
+ This feature allowed to synchronise transaction methods like begin,
commit, and rollback for a group of descriptors.
+ The feature is over engineered and not needed for `CoreDb`, neither
is it complete (some convergence features missing.)
* Add debugging helpers to `Kvt`
also:
Update database iterator, add count variable yield argument similar
to `Aristo`.
* Provide optional destructors for `CoreDb` API
why;
For the upcoming Aristo wrapper, this allows to control when certain
smart destruction and update can take place. The auto destructor works
fine in general when the storage/cache strategy is known and acceptable
when creating descriptors.
* Add update option for `CoreDb` API function `hash()`
why;
The hash function is typically used to get the state root of the MPT.
Due to lazy hashing, this might be not available on the `Aristo` DB.
So the `update` function asks for re-hashing the gurrent state changes
if needed.
* Update API tracking log mode: `info` => `debug
* Use shared `Kvt` descriptor in new Ledger API
why:
No need to create a new descriptor all the time
Add these to the list of specially disabled tests during `make test`,
as they are exceptionally slow.
