with a standalone fluffy node
* Add nph check to nimbus_verified_proxy CI lint
* Formatting nimbus_verified_proxy code with nph v0.4.1
* Update copyright years
* Change order of nph check vs copyright check
* 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.
* Remove custom block chain unit tests
why:
The custom block chain unit test functionality is superseded by
`test_coredb`.
All the custom block chains used here are hopelessly out of date and
the configs were never updated regarding fork and ttd settings (while
the production code has moved on.)
* CoreDb: Update unit tests suite
details:
Can accommodate non-built in network dumps. Inherited some functionality
from the now retired `test_custom_network` test.
* Initial implementation of era1 + export + verify
Initial implementation of era1 + export and verify command in the
existing eth_data_exporter.
* Quick verify version to test with geth created era1 files
* Add Era1File object and getter for specific block tuple
* Add getAccumulatorRoot and update AccumulatorRoot type name
+ clean-up of some comments.
* Implement BlockIndex based verify + additional helper calls
+ fix bug for reading last (incomplete) Era1 file
* Fix init BlockIndex offsets for last era + extra check on reading
* Remove duplicated e2store code
* 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
* CoreDb: Improve API and API tracking
why:
Now logs state roots where appropriate
* CoreDb: re-implement `CoreDbVidRef` => `CoreDbTrieRef`
why:
Instead of a root vertex ID wrapper, the purpose of this object type
has been upgrades to a sub-trie prototype.
caveat:
`Aristo` backend not fully functional, yet.
* CoreDb: Update `Aristo` backend
why:
Supports virtual sub-tries
* CoreDb: Account address tracking for `StorageTrie` virtual tries
details:
Supported with API tracking/logging
* CoreDb: Keep account address in payload object
why:
No need to provide extra address argument for `merge()`, also
provides tracking possibility for account debugging.
* Ledger: Update new API for `Aristo` specific storage trie handling
* CoreDb+Ledger: Update unit tests
* Fix copyright headers
* Aristo: Update unit test suite
* Aristo/Kvt: Fix iterators
why:
Generic iterators were not properly updated after backend change
* Aristo: Add sub-trie deletion functionality
why:
For storage tries linked to an account payload vertex ID, a the
whole storage trie needs to be deleted with the account.
* Aristo: Reserve vertex ID numbers for static custom state roots
why:
Static custom state roots may be controlled by an application,
e.g. for a receipt or a transaction root. The `Aristo` functions
are agnostic of what the static state roots are when different
from the internal tree vertex ID 1.
details;
The `merge()` 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.
* Aristo: Correct error code symbol
* Aristo: Update error code symbols

why:
Had a tendency to stop early leaving an incomplete job

* Run hardForkTransition before executing transactions in getBlockWitness.
* Improve logging and add help message.

* Add cleanup code, address review comments
* Disable metrics for libverifproxy only
* Update confutils
