* Provided common scheduler API, applied to `full` sync
* Use hexary trie as storage for proofs_db records
also:
+ Store metadata with account for keeping track of account state
+ add iterator over accounts
* Common scheduler API applied to `snap` sync
* Prepare for accounts bulk import
details:
+ Added some ad-hoc checks for proving accounts data received from the
snap/1 (will be replaced by proper database version when ready)
+ Added code that dumps some of the received snap/1 data into a file
(turned of by default, see `worker_desc.nim`)
* 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.
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.
* 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
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.
