Using exception in rlp.append turn out creates more problem than it solve.
`blockHash` operation is literally everywhere in nimbus-eth1, nimbus-eth2, and fluffy-code.
The compiler begins to complain about unlisted exception.
Rlp bytes coming from network and test vectors already verified by the decoder.
So, any invalid optional fields of blockheader that come into rlp.append means
programming error. Assertion will be more apropiate in this situation and less problematic.
including:
- fix rlp.append of BlockHeader
- add tests for rlp.readRecordType of BlockBody
- add tests for rlp.append of BlockHeader
- add tests for EthBlock roundtrip
* In the incomplete-db node-existence check, don't use contains.
(Using contains led to a problem with CaptureDB.)
* In the incomplete-db check, just checking len > 0 isn't right.
* Oh, I needed the AssertionDefect thing too.
* Need this when compiling under older versions of Nim.
* Sometimes we want missing nodes to be errors, sometimes not.
* Add metrics related to devp2p peer connections
* Avoid reconnecting to peers that just failed connection
- Add SeenTable to avoid reconnecting to peers immediately after
a failed connect. Depending on the failure, the amount of time is
different. This is similar to what is done in nimbus-eth2.
- Attempt to rework rlpxConnect at the same time, in order to
make sure that errors are properly handled. The current structure
is far from ideal, but it is hopefully a small step in the right
direction. To many oddities in there right now to really rework
rlpxConnect properply.
* Fix rlpx thunk fuzzer
The old code, which did it in sequence, made it take a very long
time to accumulate peers in the peer pool, particularly because
occasionally a connection-attempt would hang for a couple of minutes
before timing out.
Adds `Withdrawal` type according to EIP-4895, and extends `BlockHeader`
accordingly. Also adds RLP encoding support for `Withdrawal` to enable
building `BlockHeader` (used by Nimbus-CL in empty block prod fallback).
* persist ENRs (parsed) from the discovery5 protocol
* filter fork_digest from eth2 data
* Update eth/p2p/discoveryv5/dcli.nim

- Fix two possible RangeErrors, due to negative seq allocation
in decodeAuthMessageEIP8 and in decodeAckMessageEIP8
- Set the minimum auth message size to AuthMessageEIP8Length,
in case there are clients that no longer add padding
- Add tests for invalid length cases
RLP Enum deserialization would currently not check if "hole values"
were attempted to be converted to the enum type. Now use
checkedEnumAssign and fail with RlpTypeMismatch on invalid values.
There is at least one occurance of an enum with holes in rlpx p2p:
DisconnectionReason. For this enum the issue could occur.
Also:
- Added enum RLP tests and rlpx p2p disconnect message tests to
test the DisconnectionReason with enum hole value.
- Fixed worse custom DisconnectionReason decoding occurance
in rlpx in waitSingleMsg proc where this issue could occur.
