This allows for protocols build on top of discv5 to use the ENR
provided in the handshake directly, instead of having to rely
on requesting it from the discv5 routing table.
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).
* persist ENRs (parsed) from the discovery5 protocol
* filter fork_digest from eth2 data

- 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.
- Unify the debug log and info log into one. Removing the
redundant information
- Log the custom ENR fields more pretty
- Make the JSON format logging more pretty for several types
Nim devel brach(1.7.1) introduce gc=orc as default mode.
Because the p2p protocol using unsafe pointer operations
for it's ProtocolInfo and using global variables scattered
around, the orc mistakenly(or maybe correctly) crash the protocol.
Seems there are two occasions possible where we try to ping the
own local node which causes an assert
- One via the bounding
- One via a received ping, which is strange in the first place but
notice in a stack trace
* Move NetworkId type to common eth_types
NetworkId is after all a common type and this way it avoid an
application that requires it to also import all devp2p related
network types.
RLP related calls are moved to eth_types_rlp, this means that p2p
protocols that send NetworkId over the wire need to import this
too. Or just common in general.
* Remove # in front of multiline comment end bracket
These seem to be interpreted wrongly by the GitHub code browser.
This is specifically useful for when the failure is caused by an
"Operation not permitted", as then we can see for which specific
port(s) a firewall might be blocking outgoing traffic.
* tighter nimcrypto imports
* install openssl on macos for Nim devel
* add getTotalDifficulty base method to AbtractChainDB

`eth_types` is being imported from many projects and ends up causing
long build times due to its extensive import lists - this PR starts
cleaning some of that up by moving the chain DB and RLP to their own
modules.
this PR also moves `keccakHash` to its own module and uses it in many
places.
