* Add nph check to fluffy CI lint
* Add a section on nph usage in the fluffy.guide
* Update copyright years for altered files
* Avoid chained methods formatting style in db code
* Update nph in CI to v0.5
* Remove leftover commented import
* Move comment to avoid nph turning complex list into simple list (nph bug)
* Update nph in CI to v0.5.1
* Formatting fluffy with nph v0.5.1
This would currently manifest sometimes in state gossip test in
CI or locally. But could occur on fluffy binary in case state
network is enable and data is gossiped.
* 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
- Add Era1 helpers to be able to iterate fast over block tuples
and individual total difficulties
- Add buildAccumulator from Era1 file
- Add Era1 based BlockHeader with proof + bodies/receipts gossip
calls
- Add new JSON-RPC debug methods to be able to test the above
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
