* Use type name eth and snap (rather than snap1)
* Prettified snap/eth handler trace messages
* Regrouped sync sources
details:
Snap storage related sources are moved to common directory.
Option --new-sync renamed to --snap-sync
also:
Normalised logging for secondary/non-protocol handlers.
* Merge protocol wrapper files => protocol.nim
details:
Merge wrapper sync/protocol_ethxx.nim and sync/protocol_snapxx.nim
into single file snap/protocol.nim
* Comments cosmetics
* Similar start logic for blockchain_sync.nim and sync/snap.nim
* Renamed p2p/blockchain_sync.nim -> sync/fast.nim
* 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

* 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Also, the BaseVMState constructor has been replaced by a constructor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.
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.
Use a hard-coded number instead of the same expression as the client, so that
bugs introduced via that expression are detected. Using the same expression as
the client can hide issues when the value is wrong in both places.
When the expected value genuinely changes, it'll be obvious.
Just change this number.

* extract unused clique/mining support into separate file
why:
mining is currently unsupported by nimbus
* Replay first 51840 transactions from Goerli block chain
why:
Currently Goerli is loaded but the block headers are not verified.
Replaying allows real data PoA development.
details:
Simple stupid gzipped dump/undump layer for debugging based on
the zlib module (no nim-faststream support.)
This is a replay running against p2p/chain.persistBlocks() where
the data were captured from.
* prepare stubs for PoA engine
* split executor source into sup-modules
why:
make room for updates, clique integration should go into
executor/update_poastate.nim
* Simplify p2p/executor.processBlock() function prototype
why:
vmState argument always wraps basicChainDB
* split processBlock() into sub-functions
why:
isolate the part where it will support clique/poa
* provided additional processTransaction() function prototype without _fork_ argument
why:
with the exception of some tests, the _fork_ argument is always derived
from the other prototype argument _vmState_
details:
similar situation with makeReceipt()
* provide new processBlock() version explicitly supporting PoA
details:
The new processBlock() version supporting PoA is the general one also
supporting non-PoA networks, it needs an additional _Clique_ descriptor
function argument for PoA state (if any.)
The old processBlock() function without the _Clique_ descriptor argument
retorns an error on PoA networgs (e.g. Goerli.)
* re-implemented Clique descriptor as _ref object_
why:
gives more flexibility when moving around the descriptor object
details:
also cleaned up a bit the clique sources
* comments for clarifying handling of Clique/PoA state descriptor
