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.
* 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).
The ENR code used to be solely exception based, and these
exceptions where a left-over of that. They are useless as later
calls use Result anyhow.
Additionally, they cause quite the performance loss because they
are used in the "common path" for the toTypedRecord call, e.g.
when reading the fields of ip6, tcp6 and udp6.
Currently only setting `--styleCheck:hint` as there are some
dependency fixes required and the compiler seems to trip over the
findnode MessageKind, findnode Message field and the findNode
proc. Also over protocol.Protocol usage.
Separate the logging when the node is not reachable and
enrAutoUpdate is on or off to avoid confusion whether or not the
node might still become reachable.
queryRandom was currently only async for the `enrField` version.
However the basic queryRandom is also exported and thus gets
changed so it can be properly used as async proc.
Also added exports for the modules of which objects are used in
the discovery public API.
toBytes for NodeId wasn't selected by compiler byt if it does
get selected, it will fail on the test cases due to the
countdown that is done in logDistance.
Set to toBytesBE properly now and do countup, that should make
it correct also for BE architecture.
Removed toBytes to avoid confusion and avoid this one being
selected ever. The only place toBytes for NodeId was used is in
sessions.nim makeKey func and there also the stint one
(thus native endianness) was selected in Nim 1.2.x.
Native endianness is fine there as it is only an internal
representation.
* Don't fail ENR decoding when value is an RLP list
* Store RLP raw list in the ENR field pair instead
* Add ENR kList FieldKind so lists can be treated differently
Treated differently now when printing out the ENR, mentioning
that it is a raw RLP list
* Allow for tcp/udp ports to always be configured
- Allow for an ENR to be build with tcp and udp ports also when
no IP address is provided
- In the address set-up always provide best efforttcp and udp ports
also when configuration of external ip (and/or ports) fails.
* Modify nodes verification
* Move nodes verification to separate module
By moving verification to separate module it can be re-used
in different contexts not only in discoveryv5.
