* Fix database sort order for local txs
why:
For convenience, packed txs were stored in the block sorted by
rank->nonce. Using local accounts, the greedy grabber uses the sort
order (local,non-local)->rank->nonce which leads to a wrong calculation
of the txRoot.
* Housekeeping
details:
Replaced a couple of local eip1559TxNormalization() functions by a
single public
* Support for local accounts
why:
Accounts tagged local will be packed with priority over untagged
accounts
* Added functions for queuing txs and simultaneously setting account locality
why:
Might be a popular task, in particular for unconditionally adding txs to
a local (aka prioritised account) via "xp.addLocal(tx,true)"
caveat:
Untested yet
* fix typo
* backup
* No baseFee for pre-London tx in verifier
why:
The packer would wrongly discard valid legacy txs.
* De-noisify some Clique logging
why:
Too annoying when syncing against Goerly
* Replay devnet# and kiln sessions
why:
Compiled as local program, the unit test was used for TDD.
* dist: precompiled binaries and Docker images
The builds are reproducible, the binaries are portable and statically link librocksdb.
This took some patching. Upstream PR: https://github.com/facebook/rocksdb/pull/9752
32-bit ARM is missing as a target because two different GCC versions
fail with an ICE when trying to cross-compile RocksDB. Using Clang
instead is too much trouble for a platform that nobody should be using
anyway.
(Clang doesn't come with its own target headers and libraries, can't be
easily convinced to use the ones from GCC, so it needs an fs image from
a 32-bit ARM distro - at which point I stopped caring).
* CI: disable reproducibility test
* Activate wire protocol eth/66
and:
Disentangle protocol_eth66.nim from import sections
why:
Importing the protocol_eth66 module is not necessary. There is
no need to know too many details of the underlying wire protocol. All
that is needed will be exported by blockchain_sync.nim.
* fixes, and rebase
* Update nimbus/p2p/blockchain_sync.nim

* Fixes and rebase
Co-authored-by: Kim De Mey <kim.demey@gmail.com>
why:
TDD data and test script that are not needed for CI are externally held.
This saves space.
also:
Added support for test-custom_networks.nim to run import Devnet5 dump.
* Rearrange/rename test_kintsugu => test_custom_network
why:
Debug, fix and test more general problems related to running
nimbus on a custom network.
* Update UInt265/Json parser for --custom-network command line option
why:
As found out with the Kintsugi configuration, block number and balance
have the same Nim type which led to misunderstandings. This patch makes
sure that UInt265 encoded string values "0x11" decodes to 17, and "b"
and "11" to 11.
* Refactored genesis.toBlock() => genesis.toBlockHeader()
why:
The function toBlock(g,db) may return different results depending on
whether the db descriptor argument is nil, or initialised. This is due
to the db.config data sub-descriptor which may give various outcomes
for the baseFee field of the genesis header.
Also, the version where db is non-nil initialised is used internally
only. So the public rewrite toBlockHeader() that replaces the toBlock()
function expects a full set of NetworkParams.
* update comments
* Rename toBlockHeader() => toGenesisHeader()
why:
Polymorphic prototype used for BaseChainDB or NetworkParams argument.
With a BaseChainDB descriptor argument, the name shall imply that the
header is generated from the config fields rather than fetched from
the database.
* Added command line option --static-peers-file
why:
Handy feature to keep peer nodes in a file, similar to the
--bootstrap-file option.
* Kludge needed for setting up custom network
why:
Some non-features in the persistent hexary trie DB produce an assert
error when initiating the Kinsugi network.
details:
This fix should be temporary, only.
* Fix OS detection
why:
directive detectOs() bails out on Windows if checking for Ubuntu
* test environment for studying crash of hexary trie
why:
the persistent test case will crash unless in genesis.toBlock():
+ pruneTrie is set false, or
+ the directive "tdb.put(emptyRlpHash.data,emptyRlp)" is added right
before the "for k, v in account.storage:" loop
* different tests for OS variants
Includes a simple test harness for the merge interop M1 milestone
This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:
https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md
To execute the work-in-progress test, please run:
In terminal 1:
tests/amphora/launch-nimbus.sh
In terminal 2:
tests/amphora/check-merge-test-vectors.sh
details:
For documentation, see comments in the file tx_pool.nim.
For prettified manual pages run 'make docs' in the nimbus directory and
point your web browser to the newly created 'docs' directory.
why:
Previous version was based on lru_cache which is ugly. This module is
based on the stew/keyed_queue library module.
other:
There are still some other modules rely on lru_cache which should be
removed.
* Redesign of BaseVMState descriptor
why:
BaseVMState provides an environment for executing transactions. The
current descriptor also provides data that cannot generally be known
within the execution environment, e.g. the total gasUsed which is
available not before after all transactions have finished.
Also, the BaseVMState constructor has been replaced by a constructor
that does not need pre-initialised input of the account database.
also:
Previous constructor and some fields are provided with a deprecated
annotation (producing a lot of noise.)
* Replace legacy directives in production sources
* Replace legacy directives in unit test sources
* fix CI (missing premix update)
* Remove legacy directives
* chase CI problem
* rebased
* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation
why:
Constructing a new 'AccountsCache' descriptor can be avoided sometimes
when the current state root is properly positioned already. Such a
feature existed already as the update function 'initStateDB()' for the
'BaseChanDB' where the accounts cache was linked into this desctiptor.
The function 'initStateDB()' was removed and re-implemented into the
'BaseVmState' constructor without optimisation. The old version was of
restricted use as a wrong accounts cache state would unconditionally
throw an exception rather than conceptually ask for a remedy.
The optimised 'BaseVmState' re-initialisation has been implemented for
the 'persistBlocks()' function.
also:
moved some test helpers to 'test/replay' folder
* Remove unused & undocumented fields from Chain descriptor
why:
Reduces attack surface in general & improves reading the code.
details:
1. The check for cumulativeGasUsed + tx.gasLimit <= header.gasLimit
makes neither sense nor is it part of the Eip1559 specs. Nevertheless
a check tx.gasLimit <= header.gasLimit is added to satisfy some
unit test (see comments in validateTransaction() body.)
2. As a replacement check for the one removed in 1, a check for
cumulativeGasUsed + gasBurned <= header.gasLimit has been added
(see comments in processTransactionImpl() body.)
3. Prototypes for processTransaction() variants have been cleaned up and
commented.
why:
Detail 1. in particular produces an error for tightly packed blocks when
the last tx in the list has a generous gasLimit.
* crash test scenario
details:
Example code for inspecting nested block chain and accounts cache
database transaction framework. There seems to be a pathological
case where the system crashes after a rollback (as appeared in the
tx-pool packer code.)
* simplified crash scenario
* Workable solution (as suggested by Andri)
details:
Avoiding db.rollback() (db.commit() is OK) while vmState.stateDB is
alive.
* Rename text_txcrash => test_accounts_cache
why:
Unit tests covers part of accounts_cache handling
* comment update
Add the new [Arrow Glacier fork](https://eips.ethereum.org/EIPS/eip-4345).
Only the difficulty calculation is changed, but as a new fork it still affects
a number of places in the code.
To the best of my knowledge the change is only scheduled on Mainnet.
In addition:
- The fork date comments in `chain_config.nim` have been checked against the
real networks, set consistently in UTC instead of random timezones, and made
neater. Maybe we'll keep these when transferring config to a file someday.
- It's added to forkid hash tests (EIP-2124/EIP-2364), of course.

* PoW wrapper for verification & mining
why:
It eases data management of per-Epoch lookup tables. Also some unit
tests show limits of usefulness on non-specialised machines for
mining besides developing tests.
details:
For PoW verification, this patch provides a pretty wrapper hiding the
details of the ethash/Hashimoto lookup cache management.
For mining on my development system without special hardware, the
underlying ethash functions are prohibitively slow. It takes
* ~20 minutes to prepare the full ethash/Hashimoto lookup dataset
* a second to run ~25k nonce tests (in the mining loop)
The mining part might be of some use for generating test data for
the tx-pool, though.
* Using PowRef as replacement for EpochHashCache + hashimotoLight()
* Fix typo (CI failed)
why:
was below log level when testing locally
* fix canonical naming
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.
the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.
this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.
EIP-2718:
- chainID: Long! of Query
- chainID: Long of Transaction
EIP-1559:
- baseFeePerGas: BigInt of Block
- effectiveGasPrice: BigInt of Transaction
- maxFeePerGas: BigInt of Transaction
- maxPriorityFeePerGas: BigInt of Transaction
this is a preparation for migration to confutils based config
although there is still some getConfiguration usage in tests code
it will be removed after new config arrived
although they are technically different, but in reality,
many networks are using the same id for ChainId dan NetworkId.
in this commit, we set networkid from config file's chainId.
- allow clique period and epoch to be configured via config file
- this also activate poaEngine mode
- remove clique period configuration from cli to reduce confusion
- fix#786
