Mdbx now takes a logger - but this has not been pushed to all callers -
meaning it had an invalid logger
This fixes the log propagation.
It also fixed a start-up issue for http.enabled and txpool.disable
created by a previous merge
This fixes an issue where the mumbai testnet node struggle to find
peers. Before this fix in general test peer numbers are typically around
20 in total between eth66, eth67 and eth68. For new peers some can
struggle to find even a single peer after days of operation.
These are the numbers after 12 hours or running on a node which
previously could not find any peers: eth66=13, eth67=76, eth68=91.
The root cause of this issue is the following:
- A significant number of mumbai peers around the boot node return
network ids which are different from those currently available in the
DHT
- The available nodes are all consequently busy and return 'too many
peers' for long periods
These issues case a significant number of discovery timeouts, some of
the queries will never receive a response.
This causes the discovery read loop to enter a channel deadlock - which
means that no responses are processed, nor timeouts fired. This causes
the discovery process in the node to stop. From then on it just
re-requests handshakes from a relatively small number of peers.
This check in fixes this situation with the following changes:
- Remove the deadlock by running the timer in a separate go-routine so
it can run independently of the main request processing.
- Allow the discovery process matcher to match on port if no id match
can be established on initial ping. This allows subsequent node
validation to proceed and if the node proves to be valid via the
remainder of the look-up and handshake process it us used as a valid
peer.
- Completely unsolicited responses, i.e. those which come from a
completely unknown ip:port combination continue to be ignored.
-
The disconnect message could either be a plain integer, or a list with
one integer element. We were encoding it as a plain integer, but
decoding as a list. Change this to be able to decode any format.
This is the beginning of the series of changes to make it possible to
run multiple instances of erigon inside a single process (as devnet tool
does), with the logging from these processes going to respective log
files correctly.
This is the first part where the initial infrastructure is being
established

--nat stun is an automatic external IP detection alternative to manual --nat extip option.
It can be used both at home or on production servers without any extra setup.
It is fast (up to 5 ms) and more reliable than alternatives (as the request goes to the public internet).
This auto-detection is useful to run multiple instances of a service in cloud environments
where the node IPs are not known in advance.
