* 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.
why:
Testing against a replay unit test for Devnet4 made it necessary to
adjust the TTD handling. Without updated, importing fails at block #5646
which is the parent of the terminal PoW block. Similar considerations
apply for Devnet5 and Kiln.
- prevRandao/mixDigest = payloadAttrs.prevRandao
- timestamp = payloadAttrs.timestamp
- coinbase = payloadAttrs.suggestedFeeRecipient
- extraData = it can be anything 0-32 bytes, but currently set to empty bytes.
* Add block bodies to the propagation and lookups
- Read and propagate block bodies next to the headers
- Add block bodies content (via lookups) to the eth_getBlockByHash
call
- Test the above in test_portal_testnet
* Fix storage/propagation of block bodies
- Data format is an actual block: [header, txs, uncles], which
requires some adjustment to store the block body
- Added also `eth_getBlockTransactionCountByHash` json rpc call
Default the network key will be taken from a network key file
instead of randomly generated on each run. This is done because
the data that gets stored in the content database is dependant on
the network key used, as the node id is derived from this.
This is to avoid having a json rpc call fail if there was a
previous call done more than 10 seconds ago. 10 seconds because
that is the default timeout on the http server side.
* 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.
* Sharing block header data around in a Portal history network (PoC)
- Rework PortalStream to have an instance per PortalProtocol (this
needs to be improved eventually). Each instance uses the same
UtpDiscv5Protocol instance.
- Add processContent on receival of accepted data
- Add dumb neighborhoodGossip: dumb in the sense that it only
offers one piece of content at a time.
- Add to / adjust populate_db to also allow for propagation of
the data and add debug rpc call: portal_history_propagate
- Add eth_rpc_client
- Add eth_getBlockbyHash (no txs or uncles) to eth API
- Add additional test to test_portal_testnet which loads 5 block
headers to 1 node, and offers this data to few nodes, which should
propagate it over the network further. Next query every node for
this data.
* Adjust paths on which Fluffy CI is triggered
* Add documentation on the local testnet
Any transaction where tx.sender has a CODEHASH != EMPTYCODEHASH MUST
be rejected as invalid, where EMPTYCODEHASH =
0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470.
The invalid transaction MUST be rejected by the client and not be included
in a block. A block containing such a transaction MUST be considered invalid.
because EIP-4399 override mixDigest validation rule,
there is no need to check mixDigest == ZERO_HASH
`mixDigest` will carry POS block randomness value
