remove attestation/aggregate queue (#2519) With the introduction of batching and lazy attestation aggregation, it no longer makes sense to enqueue attestations between the signature check and adding them to the attestation pool - this only takes up valuable CPU without any real benefit. * add successfully validated attestations to attestion pool directly * avoid copying participant list around for single-vote attestations, pass single validator index instead * release decompressed gossip memory earlier, specially during async message validation * use cooked signatures in a few more places to avoid reloads and errors * remove some Defect-raising versions of signature-loading * release decompressed data memory before validating message

handle duplicate pubkeys in sync committee (#2902) When sync committee message handling was introduced in #2830, the edge case of the same validator being selected multiple times as part of a sync subcommittee was not covered. Not handling that edge case makes sync contributions have a lower-than-expected participation rate as each sync validator is only counted up through once per subcommittee. This patch ensures that this edge case is properly covered.

# Status lib

disentangle eth2 types from the ssz library (#2785) * reorganize ssz dependencies This PR continues the work in https://github.com/status-im/nimbus-eth2/pull/2646, https://github.com/status-im/nimbus-eth2/pull/2779 as well as past issues with serialization and type, to disentangle SSZ from eth2 and at the same time simplify imports and exports with a structured approach. The principal idea here is that when a library wants to introduce SSZ support, they do so via 3 files: * `ssz_codecs` which imports and reexports `codecs` - this covers the basic byte conversions and ensures no overloads get lost * `xxx_merkleization` imports and exports `merkleization` to specialize and get access to `hash_tree_root` and friends * `xxx_ssz_serialization` imports and exports `ssz_serialization` to specialize ssz for a specific library Those that need to interact with SSZ always import the `xxx_` versions of the modules and never `ssz` itself so as to keep imports simple and safe. This is similar to how the REST / JSON-RPC serializers are structured in that someone wanting to serialize spec types to REST-JSON will import `eth2_rest_serialization` and nothing else. * split up ssz into a core library that is independendent of eth2 types * rename `bytes_reader` to `codec` to highlight that it contains coding and decoding of bytes and native ssz types * remove tricky List init overload that causes compile issues * get rid of top-level ssz import * reenable merkleization tests * move some "standard" json serializers to spec * remove `ValidatorIndex` serialization for now * remove test_ssz_merkleization * add tests for over/underlong byte sequences * fix broken seq[byte] test - seq[byte] is not an SSZ type There are a few things this PR doesn't solve: * like #2646 this PR is weak on how to handle root and other dontSerialize fields that "sometimes" should be computed - the same problem appears in REST / JSON-RPC etc * Fix a build problem on macOS * Another way to fix the macOS builds Co-authored-by: Zahary Karadjov <zahary@gmail.com>

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking
