#
# General notes about the code:
# * Weird styling - the sections taken from the spec use python styling while
# the others use NEP-1 - helps grepping identifiers in spec
# * When updating the code, add TODO sections to mark where there are clear
# improvements to be made - other than that, keep things similar to spec unless
# motivated by security or performance considerations
performance fixes (#2259) * performance fixes * don't mark tree cache as dirty on read-only List accesses * store only blob in memory for keys and signatures, parse blob lazily * compare public keys by blob instead of parsing / converting to raw * compare Eth2Digest using non-constant-time comparison * avoid some unnecessary validator copying This branch will in particular speed up deposit processing which has been slowing down block replay.

# Performance notes:
# * The state transition is used in two contexts: to verify that incoming blocks
# are correct and to replay existing blocks from database. Incoming blocks
# are processed one-by-one while replay happens multiple blocks at a time.
# * Although signature verification is the slowest operation in the state
# state transition, we skip it during replay - this is also when we repeatedly
# call the state transition, making the non-signature part of the code
# important from a performance point of view.
# * It's important to start with a prefilled cache - generating the shuffled
# list of active validators is generally very slow.
# * Throughout, the code is affected by inefficient for loop codegen, meaning
# that we have to iterate over indices and pick out the value manually:
# https://github.com/nim-lang/Nim/issues/14421
# * Throughout, we're affected by inefficient `let` borrowing, meaning we
# often have to take the address of a sequence item due to the above - look
# for `let ... = unsafeAddr sequence[idx]`
# * Throughout, we're affected by the overloading rules that prefer a `var`
# overload to a non-var overload - look for `asSeq()` - when the `var`
# overload is used, the hash tree cache is cleared, which, aside from being
# slow itself, causes additional processing to recalculate the merkle tree.

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>
