`parseCmdArg` is expected to raise `ValueError` but for `enr.Record`,
`Node`, `PrivateKey`, and `NatConfig`, we raise `ConfigurationError`.
Change to `ValueError` instead.
Instead of patching BlockHeader or BlockBody codec
each time it get additional optional fields,
this PR make the rlp codec automatically handle
optional fields. Thus rlp codec overloading of
EthBlock, BlockHeader, and BlockBody can be removed.
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).
