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.
* 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

* bump rockdb
* Rename `KVT` objects related to filters according to `Aristo` naming
details:
filter* => delta*
roFilter => balancer
* Compulsory error handling if `persistent()` fails
* Add return code to `reCentre()`
why:
Might eventually fail if re-centring is blocked. Some logic will be
added in subsequent patch sets.
* Add column families from earlier session to rocksdb in opening procedure
why:
All previously used CFs must be declared when re-opening an existing
database.
* Update `init()` and add rocksdb `reinit()` methods for changing parameters
why:
Opening a set column families (with different open options) must span
at least the ones that are already on disk.
* Provide write-trigger-event interface into `Aristo` backend
why:
This allows to save data from a guest application (think `KVT`) to
get synced with the write cycle so the guest and `Aristo` save all
atomically.
* Use `KVT` with new column family interface from `Aristo`
* Remove obsolete guest interface
* Implement `KVT` piggyback on `Aristo` backend
* CoreDb: Add separate `KVT`/`Aristo` backend mode for debugging
* Remove `rocks_db` import from `persist()` function
why:
Some systems (i.p `fluffy` and friends) use the `Aristo` memory
backend emulation and do not link against rocksdb when building the
application. So this should fix that problem.
These options, inspired by Nethermind and general internet wisdom, bring
the database size down to 2/3 without affecting throughput. In theory,
they should also bring down memory usage and/or make more efficient use
of whatever memory is already assigned to rocksdb but this needs
verification in a longer test at synced-mainnet sizes.
In the meantime, they make testing easier by removing some noise that
the profiler says are bad, such as excessive SkipList access (countered
by bloom filters).
* Use RocksDb column families instead of a prefixed single column
why:
Better performance
* Use structural objects `VertexRef` and `HashKey` in LRU cache for RocksDb
why:
Avoids repeated de/serialisation
`initTable` is obsolete since nim 0.19 and can introduce significant
memory overhead while providing no benefit (since the table will be
grown to the default initial size on first use anyway).
In particular, aristo layers will not necessarily use all tables they
initialize, for exampe when many empty accounts are being created.
This PR consolidates the split header-body sequences into a single EthBlock
sequence and cleans up the fallout from that which significantly reduces
block processing overhead during import thanks to less garbage collection
and fewer copies of things all around.
Notably, since the number of headers must always match the number of bodies,
we also get rid of a pointless degree of freedom that in the future could
introduce unnecessary bugs.
* only read header and body from era file
* avoid several unnecessary copies along the block processing way
* simplify signatures, cleaning up unused arguemnts and returns
* use `stew/assign2` in a few strategic places where the generated
nim assignent is slow and add a few `move` to work around poor
analysis in nim 1.6 (will need to be revisited for 2.0)

* Fix `blobify()` for `SavedState` object
why:

why:
Stored `block-number - 1` for some obscure reason.
* Cosmetcs, docu
These options are there mainly to drive experiments, and are therefore
hidden.
One thing that this PR brings in is an initial set of caches and buffers for rocksdb - the set that I've been using during various performance tests to get to a viable baseline performance level.
The `rocksdb` version shipped with distributions is typically old and
therefore often lacks features we use - it also doesn't match the one
assumed by nim-rocksdb leading to ABI mismatch risks.
Instead of depending on the system rocksdb, we'll now use the rocksdb
version assumed by nim-rocksdb and locked in its vendor folder by always
building it together with nimbus.
This avoids the problem of unknown rocksdb versions at a (small) cost to
build time.
CI caching and full windows support for building from source [remains
TODO](https://github.com/status-im/nim-rocksdb/issues/44).
* Remove all journal related stuff
* Refactor function names journal*() => delta*(), filter*() => delta*()
* remove `trg` fileld from `FilterRef`
why:
Same as `kMap[$1]`
* Re-type FilterRef.src as `HashKey`
why:
So it is directly comparable to `kMap[$1]`
* Moved `vGen[]` field from `LayerFinalRef` to `LayerDeltaRef`
why:
Then a separate `FilterRef` type is not needed, anymore
* Rename `roFilter` field in `AristoDbRef` => `balancer`
why:
New name more appropriate.
* Replace `FilterRef` by `LayerDeltaRef` type
why:
This allows to avoid copying into the `balancer` (see next patch set)
most of the time. Typically, only one instance is running on the backend
and the `balancer` is only used as a stage before saving data.
* Refactor way how to store data persistently
why:
Avoid useless copy when staging `top` layer for persistently saving to
backend.
* Fix copyright header?
`persist` is a hotspot when processing blocks because it is run at least
once per transaction and loops over the entire account cache every time.
Here, we introduce an extra `dirty` map that keeps track of all accounts
that need checking during `persist` which fixes the immediate
inefficiency, though probably this could benefit from a more thorough
review - we also get rid of the unused clearCache flag - we start with
a fresh cache on every fresh vmState.
* avoid unnecessary code hash comparisons
* avoid unnecessary copies when iterating
* use EMPTY_CODE_HASH throughout for code hash comparison
The current implementation cannot be used practically since it causes
several full reallocations of the whole free list per deletion - it
needs to be reimplemented, or the chain cannot practically progress
beyond ~2.5M blocks where a lot of removals happen.

* Add persistent last state stamp feature
why:
This allows to run `CoreDb` without journal
* Start `CoreDb` without journal
* Remove journal related functions from `CoredDb`
* Update TDD suite logger output format choices
why:
New format is not practical for TDD as it just dumps data across a wide
range (considerably larder than 80 columns.)
So the new format can be turned on by function argument.
* Update unit tests samples configuration
why:
Slightly changed the way to find the `era1` directory
* Remove compiler warnings (fix deprecated expressions and phrases)
* Update `Aristo` debugging tools
* Always update the `storageID` field of account leaf vertices
why:
Storage tries are weekly linked to an account leaf object in that
the `storageID` field is updated by the application.
Previously, `Aristo` verified that leaf objects make sense when passed
to the database. As a consequence
* the database was inconsistent for a short while
* the burden for correctness was all on the application which led
to delayed error handling which is hard to debug.
So `Aristo` will internally update the account leaf objects so that
there are no race conditions due to the storage trie handling
* Aristo: Let `stow()`/`persist()` bail out unless there is a `VertexID(1)`
why:
The journal and filter logic depends on the hash of the `VertexID(1)`
which is commonly known as the state root. This implies that all
changes to the database are somehow related to that.
* Make sure that a `Ledger` account does not overwrite the storage trie reference
why:
Due to the abstraction of a sub-trie (now referred to as column with a
hash describing its state) there was a weakness in the `Aristo` handler
where an account leaf could be overwritten though changing the validity
of the database. This has been changed and the database will now reject
such changes.
This patch fixes the behaviour on the application layer. In particular,
the column handle returned by the `CoreDb` needs to be updated by
the `Aristo` database state. This mitigates the problem that a storage
trie might have vanished or re-apperaed with a different vertex ID.
* Fix sub-trie deletion test
why:
Was originally hinged on `VertexID(1)` which cannot be wholesale
deleted anymore after the last Aristo update. Also, running with
`VertexID(2)` needs an artificial `VertexID(1)` for making `stow()`
or `persist()` work.

* Remove crufty `pruneTrie` arguments
* Replaced legacy `distinct_trie` logic by new `ledger` functionality
why:
The module `distinct_trie` is supported by `Aristo` in trivial cases.
* Activate `test_op_memory`
This PR exploits structural properties of era files to simplify the
implementation and in particular remove the need to load all era file
indicies at startup which may be slow (due to archival storage residing
on slow drives)
* Attempt to roll back stateless mode implementation in a single PR
why:
+ Stateless mode is not fully working and in the way
+ Single PR should make it feasible to investigate for a possible
re-implementation
* Fix copyright year
* Fix annotation for exception (evmc mode)
* Update some docu & messages
* Remove cruft from the ledger modules
* Must not overwrite genesis data on an initialised database
why:
This will overwrite the global state of the Aristo single state DB.
Otherwise resuming at the last synced state becomes impossible.
* Provide latest block number from journal
why:
This relates the global state of the DB directly to the corresponding
block number.
* Implemented unit test providing DB pre-load and resume
why:
When deleting accounts while restoring the previous state, storage tries
must be deleted first. Otherwise a `DelDanglingStoTrie` error will occur
when trying to delete an account which refers to an active storage trie.
* Introduce wrapper type for EIP-4844 transactions
EIP-4844 blob sidecars are a concept that only exists in the mempool.
After inclusion of a transaction into an execution block, only the
versioned hash within the transaction remains. To improve type safety,
replace the `Transaction.networkPayload` member with a wrapper type
`PooledTransaction` that is used in contexts where blob sidecars exist.

* Aristo: Generalise alien/guest interface for piggiback on database
* Aristo: Code cosmetics
* CoreDb+Kvt: Update transaction API
why:
Use single addressable function `forkTx(backLevel: int)` as used
in `Aristo`. So `Kvt` can be synced simultaneously to `Aristo`.
also:
Refactored `kvt_tx.nim` in a similar fashion to `Aristo`.
* Kvt: Replace `LayerDelta` object by reference
why:
Will be needed when introducing filters
* Kvt: Remodel backend filter facility similar to `Aristo`
why:
This allows to operate on several KVT instances simultaneously.
* CoreDb+Kvt: Fix on-disk storage
why:
Overlooked name change: `stow()` => `persist()` for permanent storage
* Fix copyright headers
* Aristo: Rename journal related sources and functions
why:
Previously, the naming was hinged on the phrases `fifo`, `filter` etc.
which reflect the inner workings of cascaded filters. This was
unfortunate for reading/understanding the source code for actions where
the focus is the journal as a whole.
* Aristo: Fix buffer overflow (path length truncating error)
* Aristo: Tighten `hikeUp()` stop check, update error code
why:
Detect dangling vertex links. These are legit with `snap` sync
processing but not with regular processing.
* Aristo: Raise assert in regular mode `merge()` at a dangling link/edge
why:
With `snap` sync processing, partial trees are ok and can be amended.
Not so in regular mode.
Previously there was only a debug message when a non-legit dangling edge
was encountered.
* Aristo: Make sure that vertices are copied before modification
why:
Otherwise vertices from lower layers might also be modified
* Aristo: Fix relaxed mode for validity checker `check()`
* Remove cruft
* Aristo: Update API for transaction handling
details:
+ Split `aristo_tx.nim` into sub-modules
+ Split `forkWith()` into `findTx()` + `forkTx()`
+ Removed `forkTop()`, `forkBase()` (now superseded by new `forkTx()`)
* CoreDb+Aristo: Fix initialiser (missing methods)
* Aristo: Allow to define/set `FilterID` for journal filter records
why:
After some changes, the `FilterID` is isomorphic to the `BlockNumber`
scalar (well, the first 2^64 entries of a `BlockNumber`.)
The needed change for `FilterID` is that the `FilterID(0)` value is
valid part of the `FilterID` scalar. A non-valid `FilterID` entry is
represented by `none(FilterID)`.
* Aristo: Split off function `persist()` as persistent version of `stow()`
why:
In production, `stow(persistent=false,..)` is currently unused. So,
using `persist()` rather than `stow(persistent=true,..)` improves
readability and is better to maintain.
* CoreDb+Aristo: Store block numbers in journal records
why:
This makes journal records searchable by block numbers
* Aristo: Rename some journal related functions
why:
The name *journal* is more appropriate to api functions than something
with *fifo* or *filter*.
* CoreDb+Aristo: Update last/oldest journal state retrieval
* CoreDb+Aristo: Register block number with state root in journal
why:
No need anymore for extra lookup table `stRootToBlockNum` which maps
a storage root -> block number.
* Aristo: Remove unused function `getFilUbe()` from api
* CoreDb: Remove now unused virtual table `stRootToBlockNum`
why:
Was used to map a state root to a block number. This functionality
is now embedded into the recovery journal backend.
* Turn of API tracking (will fail on `fluffy`)
* Aristo: Code cosmetics, e.g. update some CamelCase names
* CoreDb+Aristo: Provide oldest known state root implied
details:
The Aristo journal allows to recover earlier but not all state roots.
* Aristo: Fix journal backward index operator, e.g. `[^1]`
* Aristo: Fix journal updater
why:
The `fifosStore()` store function slightly misinterpreted the update
instructions when translation is to database `put()` functions. The
effect was that the journal was ever growing due to stale entries which
were never deleted.
* CoreDb+Aristo: Provide utils for purging stale data from the KVT
details:
See earlier patch, not all state roots are available. This patch
provides a mapping from some state root to a block number and allows to
remove all KVT data related to a particular block number
* Aristo+Kvt: Implement a clean up schedule for expired data in KVT
why:
For a single state ledger like `Aristo`, there is only a limited
backlog of states. So KVT data (i.e. headers etc.) are cleaned up
regularly
* Fix copyright year
* Aristo+Kvt: Better RocksDB profiling
why:
Providing more detailed information, mainly for `Aristo`
* Aristo: Renamed journal `stats()` to `capacity()`
why:
`Stats()` was a misnomer
* Aristo: Provide backend read caches for key and vertex IDs
why:
Dedicated LRU caching for particular types gives a throughput advantage.
The sizes of the LRU queues used for caching are currently constant
but might be adjusted at a later time.
* Fix copyright year
* 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
* Update README
* Nimbus-main: replaced `PruneMode` options by `ChainDbMode` options
details:
For the legacy database, this changes the phrase
- `conf.pruneMode == PruneMode.Full` to the expression
+ `conf.chainDbMode == ChainDbMode.Prune`.
* Fix issues moaned about by NIM compiler

* Aristo+Kvm: Use column families for RocksDB
* Aristo+MemoryDB: Code cosmetics
* Aristo: Provide guest column family for export

* Kvt: Provide import mechanism for RoksDB guest column family
why:
So `Kvt` can piggyback on `Aristo` so there avoiding to run a second

why:
Avoiding to run two DBMS systems in parallel.

* Kvt: Update API hooks
* Aristo: Generalised merging snap proofs, now for multiple state roots
why:
This accommodates pre-loading partial tries for unit tests
* Aristo: Update some unit tests
* CoreDb+Aristo: Re-factor tracer
why:
Was bonkers anyway. The main change is that the trace journal is now
kept in a way similar to a transaction layer so that it can predictably
interact with DB transactions.
* Ledger: Debugging helper
* Update tracer unit test applicable for `Aristo`
* Fix copyright year
* Disable `dump()` function as compile time default
why:
This needs to pull in the `rocks_db` library at compile time.
* Remove cruft
* Docu/code cosmetics
* Aristo: Update `forkBase()`
why:
Was not up to the job
* Update/correct tracer for running against `Aristo`
details:
This patch makes sure that before creating a new `BaseVMState` the
`CoreDb` context is adjusted to accommodate for the state root that
is passed to the `BaseVMState` constructor.
* CpreDb+legacy: Always return current context with `ctxFromTx()`
why:
There was an experimental setting trying to find the node with the
proper setting in the KVT (not the hexary tie layer) which currently
does not work reliable, probably due to `Ledger` caching effects.
* Aristo: Provide descriptor fork based on search in transaction stack
details:
Try to find the tx that has a particular pair `(vertex-id,hash-key)`,
and by extension try filter and backend if the former fails.
* Cleanup & docu
* CoreDb+Aristo: Implement context re-position to earlier in-memory state
why:
It is a easy way to explore how there can be concurrent access to the
same backend storage DB with different view states. This one can access
an earlier state from the transaction stack.
* CoreDb+Aristo: Populate tracer stubs with real functionality
* Update `tracer.nim` to new API
why:
Legacy API does not sufficiently support `Aristo`
* Fix logging problems in tracer
details:
Debug logging turned off by default
* Fix function prototypes
* Add Copyright header
* Add tables import
why:
For older compiler versions on CI
* CoreDb+Aristo: Fix handler code
* Aristo+Kvt: Remove cruft
* Aristo+Kvt: The function `forkTop()` always provides a single transaction
why:
Previously it provided a single squashed tx only if there were any. Now
it will provide a blind one if there were none.
* Fix Copyright header
* Fix 'value out of range' RangeDefect caused by large/expensive blocks/transactions during DOS period.
* Clear witness cache in AccountCache persist.
* Revert previous fix and force clear cache after processing each block.
* Revert clear cache in process block.
* 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
why:
Ignoring `nil` objects was handy for a while but eventually led to
lazy programming which in turn led to double destructor calls for
the rocks-db.
* Aristo+Kvt: Fix backend `dup()` function in api setup
why:
Backend object is subject to an inheritance cascade which was not
taken care of, before. Only the base object was duplicated.
* Kvt: Simplify DB clone/peers management
* Aristo: Simplify DB clone/peers management
* Aristo: Adjust unit test for working with memory DB only
why:
This currently causes some memory corruption persumably in the
`libc` background layer.
* CoredDb+Kvt: Simplify API for KVT
why:
Simplified storage models (was over engineered) for better performance
and code maintenance.
* CoredDb+Aristo: Simplify API for `Aristo`
why:
Only single database state needed here. Accessing a similar state will
be implemented from outside this module using a context layer. This
gives better performance and improves code maintenance.
* Fix Copyright headers
* CoreDb: Turn off API tracking
why:
CI would ot go through. Was accidentally turned on.
* Add new RocksNamespaceRef type and remove backups and readonly support from RocksDb KvStore.
* Bump nim-rocksdb to fc2ba4a836b6b47ae1b17d1c45801c7e06585e19
* Fix tests.
* Fix copyright notice.
* Aristo: Remove cruft
* Prettifying profile statistics printing & source code cosmetics
* Aristo/Kvt: API tools update
* CoreDb: Corrections, mostly API related
* CoreDb: Changed the tracer `logDb()` result
why:
Only the key-value table is used from the logger database
* CoreDb: Update legacy tracer
why:
The `contains()` directive did not correspond to `0 < get().len`
also:
Copy `CoreDb` meta settings like `trackLegaApi`, `trackNewApi`, etc. to
overlay tracer descriptor
* CoreDb: Extend/update tracer API
why:
Get ready for accommodating `Aristo` tracer
* Fix missing import
why:
Some CI compilers might have (cached?) a different NIM patch level
* Ditto
* Aristo/Kvt: Provide function hooks APIs
why:
These APIs can be used for installing tracers, profiling functoinality,
and other niceties on the databases.
* Aristo: Provide optional API profiling
details:
It basically is a re-implementation of the `CoreDb` profiling
implementation
* Kvt: Provide optional API profiling similar to `Aristo`
* CoreDb: Re-implementing profiling using `aristo_profile`
* Ledger: Re-implementing profiling using `aristo_profile`
* CoreDb: Update unit tests for maintainability
* update copyright dates
* CoreDb: Provide default db backend symbols
why:
Handy for running `Aristo` against standard tests
note:
These defaults are currently set to legacy DB types. The must be
enabled manually in `db/core_db.nim`.
* Provide `Aristo` for macro assembler related tests
caveat:
Some tests use `initStorageTrie()` which lets `Aristo` bail out. The
test need to run on `distinct_ledgers` (or something like) rather than
`distinct_tries`.
* Tests: Misc modules that can run on `Aristo` as well
* NoHive: Module that can run on `Aristo` as well
* Fix copyright year
* ditto
* Aristo: Reorg `hashify()` using different schedule algorithm
why:
Directly calculating the search tree top down from the roots turns
out to be faster than using the cached structures left over by `merge()`
and `delete()`.
Time gains is short of 20%
* Aristo: Remove `lTab[]` leaf entry object type
why:
Not used anymore. It was previously needed to build the schedule for
`hashify()`.
* Aristo: Avoid unnecessary re-org of the vertex ID recycling list
why:
This list can become quite large so a heuristic is employed whether
it makes sense to re-org.
Also, re-org check is only done by `delete()` functions.
* Aristo: Remove key/reverse lookup table from tx layers
why:
It is ignored except for handling proof nodes and costs unnecessary
run time resources.
This feature was originally needed to accommodate the mental transition
from the legacy MPT to the `Aristo` trie :).
* Fix copyright year
* CoreDb: update test suite
* Aristo: Simplify reverse key map
why:
The reverse key map `pAmk: (root,key) -> {vid,..}` as been simplified to
`pAmk: key -> {vid,..}` as the state `root` domain argument is not used,
anymore
* Aristo: Remove `HashLabel` object type and replace it by `HashKey`
why:
The `HashLabel` object attaches a root hash to a hash key. This is
nowhere used, anymore.
* Fix copyright
* Aristo: Update schedule runner for `hashify()`
why:
Width-first schedule walker overlooked resolvable vertex and ended in
a deadlock situation
* CoreDb+Aristo: Update error code for fringe condition
* Ledger: Remove redundant extra MPT hashing statements
why:
These statement were used for troubleshooting
* CoreDb: Couch medicine for legacy DB backend
why:
MPT will occasionally enter inconsistent states after deletion, some
dirty fix is randomly added to mitgate that.
* Added procs to get and store block witness in db and add generate-witness cli flag.
* Completed initial implementation of block witness storage.
* Added test to verify witness is persisted to db after call to persistBlock.
* Update getBlockWitness to return witness using Result type.
* Make generate witness parameter hidden.
* CoreDb: Test module with additional sample selector cmd line options
* Aristo: Do not automatically remove a storage trie with the account
why:
This is an unnecessary side effect. Rather than using an automatism, a
a storage root must be deleted manually.
* Aristo: Can handle stale storage root vertex IDs as empty IDs.
why:
This is currently needed for the ledger API supporting both, a legacy
and the `Aristo` database backend.
This feature can be disabled at compile time by re-setting the
`LOOSE_STORAGE_TRIE_COUPLING` flag in the `aristo_constants` module.
* CoreDb+Aristo: Flush/delete storage trie when deleting account
why:
On either backend, a deleted account leave a dangling storage trie on
the database.
For consistency nn the legacy backend, storage tries must not be
deleted as they might be shared by several accounts whereas on `Aristo`
they are always unique.
* Update experimental rpc test to do further validation on proof responses.
* Enable zero value storage slots in the witness cache data so that proofs will be returned when a storage slot is updated to zero. Refactor and simplify implementation of getProofs endpoint.
* Improve test validation.
* Minor fixes and added test to track the changes introduced in every block using a local state.
* Refactor and cleanup test.
* Comments added to test and account cache fixes applied to account ledger.
* Return updated storage slots even when storage is empty and add test to build.
* Fix copyright and remove incorrect depth check during witness building in writeShortRlp assertion.
* 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
