Addresses https://github.com/status-im/nim-beacon-chain/issues/1366
this resolves some peer counting issues that were happening because the
lifetime future in PeerInfo was unreliable (multiple PeerInfo instances
existed per peer)
In addition, this solves another race condition: when connecting to a
peer and later dialling that protocol, it is not certain that the same
connection will be used if there's a concurrent incoming peer connection
ongoing - better not make too many assumptions about who sent statuses
when.
* removed the BlockPool type and all of the proxy functions around it - passing the chain DAG and the quarantine explicitly where appropriately - they don't need to be bundled in a type
* fixed the build after the rebase
* limit attestations kept in attestation pool
With fork choice updated, the attestation pool only needs to keep track
of attestations that will eventually end up in blocks - we can thus
limit the horizon of attestations that we keep more aggressively.
To get here, we expose getEpochRef which gets metadata about a
particular epochref, and make sure to populate it when a block is added
- this ensures that state rewinds during block addition are minimized.
In addition, we'll use the target root/epoch when validating
attestations - this helps minimize the number of different states that
we need to rewind to, in general.
* remove CandidateChains.justifiedState
unused
* remove BlockPools.Head object
* avoid quadratic quarantine loop
* fix
This also assigns precise types to the constants in the minimal
and mainnet presets in order to reduce the chance of compilation
errors when custom presets are used (previously, only the custom
presets have precisely assigned types for the constants).
* cleanups
* fix ncli state root check flag
* add block dump to ncli_db
* limit ncli_db benchmark length
* tone down finalization logs
* introduce trusted blocks
We only store blocks whose signature we've verified in the database - as
such, there's no need to check it again, and most importantly, no need
to deserialize the signature when loading from database.
50x startup time improvement, 200x block load time improvement.
* fix rewinding when deposits have invalid signature
* speed up ancestor iteration by avoiding copy
* avoid deserializing signatures for trusted data
* load blocks lazily when rewinding (less memory used)
* chronicles workarounds
* document trustedbeaconblock
* reorder ssz
* split into hash_trees and ssz_serialization, roughly, for hashing and
IO
* move bitseqs into ssz (from stew)
* clean up imports
* docs, imports
The lack of body of `goodbye` in sync_protocol.nim was preventing
the respective LibP2P protocol to be mounted and advertised on the
network.
Adding a body fixes that, but I've also made some changes in the
P2P protocol codegen that will prevent the issue from happening
again (no body is now considered the equivalent of having an empty
body).
* switch state cache to use ref statedata objects to limit memory usage
* more directly initialize ref StateData
* use HashedBeaconState instead of StateData to try to fix memory leak
* switch cache to seq[ref HashedBeaconState]
* remove unused import

We no longer discriminate between ENR, MultiAddress or ENode
bootstrap records (all of them are remapped to ENodes).
The discovery loop will stochastically try to reconnect to
accidentally disconnected nodes.
* Move BeaconNode type to its own file (fewer imports)
* disentangle sync protocol/request manager
* fix some old nimisms
* de-fear some logs
* simplify eth1 data production
* add stack tracing to release builds
* drop release compile flag for testnet
* off-by-one error in the returned range of blocks
* larger request time-outs to deal with non-responsive servers
* fix an unhandled exception when we fail to deliver a response chunk
The number of user nodes is now specified with `USER_NODES`.
To make the instructions more stable, the "numeric id" of the user
nodes will be starting from 0 (so you can always use `run_node.sh 0`
to start a user node).
If you specify a node index above the total number of nodes, you'll
launch a node without any validators attached (this is useful for
testing the sync for example).
