* 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*`.
* Provide dedicated functions for fetching accounts and storage trees
why:
Different prototypes for each class `account`, `generic` and
`storage`.
* Remove `fetchPayload()` and other cruft from API, `aristo_fetch`, etc.
* Fix typos, debugging left overs, comments
For the block cache to be shared between column families, the options
instance must be shared between the various column families being
created. This also ensures that there is only one source of truth for
configuration options instead of having two different sets depending on
how the tables were initialized.
This PR also removes the re-opening mechanism which can double startup
time - every time the database is opened, the log is replayed - a large
log file will take a long time to open.
Finally, several options got correclty implemented as column family
options, including an one that puts a hash index in the SST files.
* Provide dedicated functions for deleteing accounts and storage trees
why:
Storage trees are always linked to an account, so there is no need
for an application to fiddle about (e.g. re-cycling, unlinking)
storage tree vertex IDs.
* Remove `delete()` and other cruft from API, `aristo_delete`, etc.
* clean up delete functions
details:
The delete implementations `deleteImpl()` and `delTreeImpl()` do not
need to be super generic anymore as all the edge cases are covered by
the specialised `deleteAccountPayload()`, `deleteGenericData()`, etc.
* Avoid unnecessary re-calculations of account keys
why:
The function `registerAccountForUpdate()` did extract the storage ID
(if any) and automatically marked the Merkle keys along the account
path for re-hashing.
This would also apply if there was later detected that the account
or the storage tree did not need to be updated.
So the `registerAccountForUpdate()` function was split into a part
which retrieved the storage ID, and another one which marked the
Merkle keys for re-calculation to be applied only when needed.
* Remove unused `merge*()` functions (for production)
details:
Some functionality moved to test suite
* Make sure that only `AccountData` leaf type is exactly used on VertexID(1)
* clean up payload type
* Provide dedicated functions for merging accounts and storage trees
why:
Storage trees are always linked to an account, so there is no need
for an application to fiddle about (e.e. creating, re-cycling) with
storage tree vertex IDs.
* CoreDb: Disable tracer functionality
why:
Must be updated to accommodate new/changed `Aristo` functions.
* CoreDb: Use new `mergeXXX()` functions
why:
Makes explicit vertex ID management obsolete for creating new
storage trees.
* Remove `mergePayload()` and other cruft from API, `aristo_merge`, etc.
* clean up merge functions
details:
The merge implementation `mergePayloadImpl()` does not need to be super
generic anymore as all the edge cases are covered by the specialised
functions `mergeAccountPayload()`, `mergeGenericData()`, and
`mergeStorageData()`.
* No tracer available at the moment, so disable offending tests
The state root computation here is one of the major hotspots in block
processing - in the cases the code only needs to know if it's empty or
not, it can be done a lot faster.
Adding a separate function for this looks fragile and should probably be
revisited.
Broadly, when importing blocks we don't need a transaction / frame per
block because we can simply abort the whole update and try again with a
smaller range if we find a faulty block.
Of course, this applies mainly to semi-trusted blocks where we're not
expected to fail in applying them - this could be blocks either from
files or header-verified blocks as given by consensus.
The module name is a misnomer, because AccountsCache have been
replaced by LedgerRef. But the test still applicable.
Instead of replaying unsupported goerli blocks,
we generate our own transactions and block.
* Remove AccountStateDB
AccountStateDB should no longer be used.
It's usage have been reduce to read only operations.
Replace it with LedgerRef to reduce maintenance burden.
* remove extra spaces

When performing block import, we can batch state root verifications and
header checks, doing them only once per chunk of blocks, assuming that
the other blocks in the batch are valid by extension.
When we're not generating receipts, we can also skip per-transaction
state root computation pre-byzantium, which is what provides a ~20%
speedup in this PR, at least on those early blocks :)
We also stop storing transactions, receipts and uncles redundantly when
importing from era1 - there is no need to waste database storage on this
when we can load it from the era1 file (eventually).
State lookups potentially trigger expensive re-hashings - this is the
first of several steps to remove the unnecessary ones from the general
flow of block processing
* avoid re-reading parent block header from database when it's already
in memory
* 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)
* Bump nim-eth, nim-web3, nimbus-eth2
- Replace std.Option with results.Opt
- Fields name changes
* More fixes
* Fix Portal stream async raises and portal testnet Opt usage
* Bump eth + nimbus-eth2 + more fixes related to eth_types changes
* Fix in utp test app and nimbus-eth2 bump
* Fix test_blockchain_json rebase conflict
* Fix EVMC block_timestamp conversion plus commentary
