This is a workaround following hive example, because one of the test case
withdrawalsAmountBounds.json, have bad blocks between good blocks.
And that bad blocks contains big int too big to fit in uint64 of
withdrawal amount field.
Clients who still importing concatenated blocks cannot pass all tests.
previously, the withdrawal validation is in process_block only,
but the one in persist block, which is also used in synchronizer
is not validated properly.
* Added missing deferred cleanup directive to sub-test functions
why:
Rocksdb keeps the files locked for a short while leading to errors. This
was previously solved my using different db sub-directories
* Provide vertex deep-copy function globally.
why:
is just handy
* Avoid unnecessary vertex caching when merging proof nodes
also:
Run all merge tests on the rocksdb backend
Previously, proof node tests were run without backend
* Fix vertex ID generator state handling for rocksdb backend
why:
* Key error in walk iterator
* Needs to be loaded when opening the database
* Use non-zero sub-table prefixes for rocksdb
why:
Handy for debugging
* Fix error code for missing key on rocksdb backend
why:
Previously returned `VOID_HASH_KEY` rather than `GetKeyNotFound`
* Explicitly copy vertex data between internal table and function/result argument
why:
Function argument or return reference may still refer to the same data
object.
* Updated error symbols
why:
Error symbol names for the hike module now start with the prefix `Hike`.
* Write back modified branch node into local top layer cache
why:
With the backend available, the source of the branch node references
might not be the top layer cache. So any change must be explicitely
recorded.
* Generalised Aristo DB constructor for any type of backend
details:
* Records to be deleted are represented as key-void (rather than
key-value) pairs by the put-function arguments
* Allow direct driver access, iterators as example implementation and
for testing.
* Provide backend storage interface
details:
Stores the top layer onto backend tables
* Implemented Rocks DB backend
details:
Transaction based `put()` functionality
Iterators (based on direct RocksDB access)
* Fix include
why:
Eth67 not default yet so that got missed
* Rename `LeafKey` => `LeafTie`
why:
Name is a pen picture of what this object is for. Also, it avoids the
ubiquitous term `key`.
* Provided `getOrVoid()` wrapper for `getOrDefault()`
also:
Provide `isValid()` syntactic sugar for `.isNil.not`, `!= 0` etc.
Reorg descriptor source, split into sub-sources
* Bundled `NodeKey` objects with root ID and called it `HashLabel`
why:
`NodeKey` (aka repurposed Hash265) objects are unique only within a
particular sub-trie (e.g. storage slots) which are kept separated
(i.e non-interleaved) by design. This is not applied to the backend
as the map VertexID->NodeKey labelling the nodes needs not be injective.
For the in-memory database (transaction) layers, the injective map
VertexID->(VertexID,NodeKey) is used where the first field of the image
tuple is the root ID of the sub-trie the `NodeKey` object is valid. So
identical storage tries for different accounts can be represented.
* Exclude some storage tests
why:
These test running on external dumps slipped through. The particular
dumps were reported earlier as somehow dodgy.
This was changed in `#1457` but having a second look, the change on
hexary_interpolate.nim(350) might be incorrect.
* Redesign `Aristo DB` descriptor for transaction based layers
why:
Previous descriptor layout made it cumbersome to push/pop
database delta layers.
The new architecture keeps each layer with the full delta set
relative to the database backend.
* Keep root ID as part of the `Patricia Trie` leaf path
why;
That way, forests are supported
* Fix missing Merkle key removal in `merge()`
* Accept optional root hash argument in `hashify()`
why:
For importing a full database, there will be no proof data except the
root key. So this can be used to check and set the root key in the
database descriptor.
also:
Associate vertex ID to `hashify()` error return code
* Added Aristo Trie traversal function
why:
* step along leaf vertices in sorted order
* tree/trie consistency checks when debugging
* Enabled storage slots test data for Aristo DB
* Keep vertex ID generator state with each db-layer
why:
The vertex ID generator state is part of the difference to the below
layer
* Move otherwise unused source to test directory
* Add Merkle hash generator
also:
* Verification facility for debugging
* Empty Merkle key hashes encoded as `EMPTY_ROOT_HASH`
details:
1. Merging a leaf vertex merges a `Patricia Trie` path (while
adding/modiying vertices) and adds a leaf node with payload
2. Merging a Merkel node merges a single vertex to the `Patricia Trie`
and registers merkel hashes
3. Action 2 can be used before action 1 in order to construct a
Merkel proof as required for handling `snap/1` data.
4. Unit tests show that action 3 is benign for now :)
* Unit tests update, code cosmetics
* Fix segfault with zombie handling
why:
In order to save memory, the data records of zombie entries are removed
and only the key (aka peer node) is kept. Consequently, logging these
zombies can only be done by the key.
* Allow to accept V2 payload without `shanghaiTime` set while syncing
why:
Currently, `shanghaiTime` is missing (alt least) while snap syncing. So
beacon node headers can be processed regardless. Normal (aka strict)
processing will be automatically restored when leaving snap sync mode.
* Cosmetics, renamed fields (eVtx, bVtx) -> (eVid, bVid)
* Multilayered delta architecture for Aristo DB
details:
Any VertexID or data retrieval needs to go down the rabbit hole and
fetch/get/manipulate the bottom layer -- even without explicit
backend.
* Direct reference to backend from top-level layer
why:
Some services as the vid management needs to be synchronised among all
layers. So access is optimised.
* Experimental MP-trie
why:
Deleting records is a infeasible with the current structure
* Added vertex ID recycling management
Todo:
Provide some unit tests
* DB layout update
why:
Main news is the separation of `Merkel` hashes into an extra table.
details:
The code fragments cover conversion between compact MPT records and
Aristo DB records as well as some rudimentary cache handling for
the `Merkel` hashes (i.e. the extra table entries.)
todo:
Add some simple unit test for the descriptor record (currently used
for vertex ID management, only.)
* Updated vertex ID recycling management
details:
added simple unit tests (mainly testing ABI)
* docu update
* Set maximum time for nodes to be banned.
why:
Useless nodes are marked zombies and banned. They a kept in a table
until flushed out by new connections. This works well if there are many
connections. For the case that there are a few only, a maximum time is
set. When expired, zombies are flushed automatically.
* Suspend full sync while block number at beacon block
details:
Also allows to use external setting from file (2nd line)
* Resume state at full sync after restart (if any)
