* 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.
* 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.
- 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.
`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.
* Fix stability issues
why:
Handling malformed messages typically raises `RangeError` exceptions
when de-serialising RLP, or decoding message data. This is an
(incomplete) attempt to weed out some out it driven by real live
tests.
remark:
Employing the new `snap` protocol there might be different views on what
the messages really contain (currently specs are more a hint.)
* Update RLP exception handling
* Undo effect-less patch
why:
problem occurred somewhere above the try/catch handler
* Using `checkedEnumAssign()` for RLP enum
* Provide dedicated `DisconnectionReason` enum type RLP reader
why:
Without this reader, the program communicating via RLPX will crash when
receiving out of bound reason codes disconnect message.
Out of bound value assignments to an enum causes a `RangeError`defect
and consequently the program to terminate. This `RangeError` is avoided
here and a `MalformedRlpError` catchable error raised.
* Using default exception type in bespoke `read(DisconnectionReason)`
why:
This should not differ from the default enum parser. The particular
message is different and more targeted, here.
Note: The default RLP parser was not used because `
`array[1,DisconnectionReason]` is currently not properly handled and
should give a siliar error message as a `DisconnectionReason` error.
* De-clutter, custom read() was not needed

* Handle the decodeAuthMessage error case separatly and log to trace
Garbage data on the TCP port (e.g. from port scanners) would
cause lots of error log messages, so log this to trace and get rid
of a (little) bit of exception usage in the process.
* Remove usage of result var in rlpxAccept and rlpxConnect
* Discv4: Add ENRRequest & ENRResponse msgs to avoid fails on these
Fix#499
These messages are not implemented yet however, but just ignored.
* disc: updateExternalIp()
New public proc that can be used to inform the discovery subsystem about
a changed external IP (as reported by UPnP/NAT-PMP in some other module).
