bandwidth and CPU usage)
* update stability subnets in ENR on startup
* log gossip state

* document stuff
* add random include
* don't overwrite subscription state when not subscribed

and may cause gossip to disconnect itself completely - use a simple head
distance instead
* fix gossip disconnection - if in hysteresis, node.gossipState will be
set to disabled even though we don't disable topic subscriptions
* fix extra duty registration call
Similar to the existing `RewardInfo`, this PR adds the infrastructure
needed to export epoch processing information from altair+. Because
accounting is done somewhat differently, the PR uses a fork-specific
object to extrct the information in order to make the cost on the spec
side low.
* RewardInfo -> EpochInfo, ForkedEpochInfo
* use array for computing new sync committee
* avoid repeated total active balance computations in block processing
* simplify proposer index check
* simplify epoch transition tests
* pre-compute base increment and reuse in epoch processing, and a few
other small optimizations
This PR introduces the type and does the heavy lifting in terms of
refactoring - the tools that use the accounting will need separate PR:s
(as well as refinements to the exportred information)
* "official" -> "scenarios", like the submodule
* fewer test binaries - various compile hacks have been improved over
time, test suite should follow
* remove obsolete bls tests - there are better test vectors in
nim-blscurve
* remove obsolete mentions of `ssz_testing`
* remove obsolete comments about proc vs globals, unittest2 already uses
proc's
This extends `mock_blocks` support to also allow producing Merge blocks.
The only step missing was initialization of the `ExecutionPayload` to an
empty value (as created by `build_empty_execution_payload`).
So far, `withState` and `withBlck` templates could only be used to have
convenience access to fork-agnostic BeaconState and BeaconBlock fields.
This patch:
- injects an additional `stateFork` constant that allows to use
`when` expressions to also access Altair and Merge-specific fields.
- introduces a `withStateAndBlck` template to support operating on both
a `BeaconState` and `BeaconBlock` at a time.
- makes sync committee related functions Merge aware.
- changes a couple if-else trees for forks into case statements so that
forgotten future forks are promoted to compile-time errors.
So far, SSZ tests for `uint128` and `uint256` integers were disabled
due to "compile-time issues". The code has been adjusted to support
those additional test vectors, and the corresponding tests have been
enabled.
In tests, the private key was put into the validator deposit's withdraw
credentials so that it can be recovered later. This leads to problems
when creating the validators through other means that do not put the key
there. In general, mock private keys only depend on the validator index,
though, and because it is clear what the index of a validator is, it is
not actually needed to put the key into the credentials.
There are a number of locations in the code that get attestations on a
forked beacon state. For attestation pools test, a convenience wrapper
was available to reduce clutter. This patch integrates that wrapper into
the core component so that it can also take advantage of the wrapper.
Replaced non-conventional `-Present` form in copyright headers with the
more appropriate `-2021` version that is already used by the majority of
the code base. Copyright header should indicate the years during which
the specific file was modified.
There are multiple ways how states can be processed during tests. One is
through tests/mocking, the other through tests/xxxutil. Both methods can
create genesis states with a set of deposits from mock validators. The
private keys for those validators are created differently, though. While
tests/mocking generates random keys, testblockutil generates fixed keys.
This is a problem when mixing both tests/mocking and testblockutil in a
single test case, as they assume that the deposits were generated using
the same method. This patch aligns the key generation across tests.
The initialization of a `SyncAggregate` to its default value is not very
intuitive. There is an `init` function in `sync_committee_msg_pool` that
provides a convenience wrapper. This patch exports that initializer so
that the rest of the code base can also take advantage of it.
Adds a function that constructs a Merkle proof for a generalized index.
This will be used during light client sync to update light clients with
a new state (see NEXT_SYNC_COMMITTEE_INDEX / FINALIZED_ROOT_INDEX).
The phase0 and altair overloads of `makeBeaconBlock` slightly differ in
their signatures which makes using them unnecessarily verbose.
- A placeholder `sync_aggregate` argument similar to `executionPayload`
is added to the phase0 overload to match the altair signature.
- A wrapper operating on `ForkedHashedBeaconState` is introduced.
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.
testblockutil currently fails to add test blocks to Altair state because
it assumes phase0 blocks in various places. This patch corrects this
limitation by using forked types internally. Note that existing clients
so far solely operate on phase0 blocks and should eventually be updated.
* Add parallel attestation verification
* Update tests, batchVerify doesn't use the threadpool with only single core (nim-blscurve update)
* bump nim-blscurve
* Debug info for failing eth2 test vectors
* remove submodule eth2-testnets
* verbose debugging of make failure on Windows (libbacktrace?)
* Remove CI debug mode
* initialization convention
* Fix new altair tests
When creating beacon blocks, the state needs to be advanced to the new
slot to determine the correct proposer index. In #875 a regression got
introduced that removed this logic when mocking blocks. Existing tests
failed to detect this, as they do not make use of the proposer index.
This patch re-introduces the state advancement, fixing the problem.
Currently, only the function to mock a block at next slot is exported.
A more generic function that allows specifying any slot is available but
not exported. This patch marks that function to also be exported.
The mocking framework was limited to chain configurations that do not
include Altair at genesis. This patch extends it so that genesis states
can be generated that are already upgraded to Altair. This is useful for
tests such as eth2spec/test/altair/unittests/test_sync_protocol.py.
The `initGenesisState` function to mock genesis states for testing was
originally introduced with a `genesis_time` parameter in #326. However,
this parameter was never respected and genesis state was always mocked
with `genesis_time` assumed to be 0. Since there is no test overriding
`genesis_time`, the parameter is removed until needed.

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

The spec imports are a mess to work with, so this branch cleans them up
a bit to ensure that we avoid generic sandwitches and that importing
stuff generally becomes easier.
* reexport crypto/digest/presets because these are part of the public
symbol set of the rest of the spec types
* don't export `merge` types from `base` - this causes circular deps
* fix circular deps in `ssz/spec_types` - this is the first step in
disentangling ssz from spec
* be explicit about phase0 vs altair - longer term, `altair` will become
the "natural" type set, then merge and so on, so no point in giving
`phase0` special preferential treatment
Simpler module name for stuff that covers forks
* check that runtime config matches database state
* also include some assorted altair cleanups
* use "standard" genesis fork in local testnet to work around missing
runtime config support
* update validator key cache on startup
Versions prior to 1.1.0 do not write a validator key cache at all.
Versions from 1.4.0 and upwards require an immutable validator key cache
to verify blocks - normally, block verification fills the cache but that
assumes that at least one block was verified by a version that has the
key cache.
Taken together, this breaks direct upgrades from anything <1.1.0 to
1.4.0.
The fix is simply to refresh fill the cache from an existing state on
startup.
* also log serious block validation failures at info level
* bump libp2p
* altair sync v2
Use V2 sync requests after the altair fork has happened, according to
the wall clock
* Fix the behavior of the v1 req/resp calls after Altair

* 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

of time - better store them in uncompressed format which makes behaviour
just after startup faster / more predictable.

as well (one less cache to keep in sync)
* bump blscurve, introduce loadValid for known-to-be-valid keys

epoch, when applying states and slots
* load state cache for each slot/block (for longer slot jumps)

* look up two state cache epochs, instead of the same epoch twice :)
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
* update ChainDAG.effective_balance() to use StateData; rm unused ChainDAG.getBlockByPreciseSlot()
* update get_effective_balances to avoid god object; avoid most memory allocation in Altair epoch reward and penalty processing
* gossip_to_consensus -> block_processor (it's processing only blocks,
but not only from gossip)
* measure queue and validation time for blocks
* measure assignment and state loading times for updateStateData
* avoid some unnecessary block copies in block sync
* warn that database is corrupt if we hit tail without a state
* proposed structure for hf1
* refactor datatypes.nim into datatypes/{base, phase0, hf1}.nim
* hf1 is Altair
* some syncing with alpha 2
* adjust epoch processing to disambiguate access to RewardFlags
* relocate StateData to stay consistent with meaning phase 0 StateData
* passes v1.1.0 alpha 5 SSZ consensus object tests
* Altair block header test fixtures work

* slot sanity and all but a couple epoch transition tests switched to Altair
* attestation Altair test fixtures work
* Altair block sanity test fixtures work
* add working altair sync committee tests

The `kvstore` design we're using now turns out to not be the best way to
use `sqlite` - in particular, there are some significant benefits to
using rowid in certain situations and to keep data in separate tables.
With this branch, there are massive improvements in startup time
(seconds instead of minutes) and state/block storage and pruning times
(milliseconds instead of seconds) - these improvements can in particular
be seen on slow drives and translate directly into better attestation
performance.
* update kvstore to new keyspace design
* remove `DirStoreRef` and the hidden `--state-db-kind` option - this
was an experiment to store large blobs in files, but with the new
kvstore, there's no compelling reason to do so
* remove `DbMap` - unused and would need updating for new keyspace
design
* introduce separate tables for each data type (blocks, states etc)
* remove "WITHOUT ROWID" pessimization for tables with large blobs
* close DbSeq statements explicitly (and earlier)
* store beacon block summaries in separate table, without SSZ
compression and load them all with single query on startup
* stop storing backwards compat full states
* mark genesis beacon block as trusted
* avoid faststreams when loading SSZ data
* remove `DisagreementBehavior` (unused)
This PR decreases the lead subscription time which should help
decrease bandwidth usage and CPU making the subscription for future
aggregation happen a bit later. There's room for more tuning here,
probably.
* fix missing negation from in #2550
* fix silly bitarray issues
* decrease subnet lead subscription time
* log all subnet switching source data
* rename subnet trackers to refer to stability and aggregate subnets
* more tests
Currently, we have a bit of a convoluted flow where when sending
attestations, we start broadcasting them over gossip then pass them to
the attestation validation to include them in the local attestation pool
- it should be the other way around: we should be checking attestations
_before_ gossipping them - this serves as an additional safety net to
ensure that we don't publish junk - this becomes more important when
publishing attestations from the API.
Also, the REST API was performing its own validation meaning
attestations coming from REST would be validated twice - finally, the
JSON RPC wasn't pre-validating and would happily broadcast invalid
attestations.
* Unified attestation production pipeline with the same flow for gossip,
locally and API-produced attestations: all are now validated and entered
into the pool, then broadcast/republished
* Refactor subnet handling with specific SubnetId alias, streamlining
where subnets are computed, avoiding the need to pass around the number
of active validators
* Move some of the subnet handling code to eth2_network
* Use BitArray throughout for subnet handling
This also makes future efforts to provide metrics and logs for
attestation efficiency easier
* Export rewards from epoch transition
* Use less memory for reward calculation (bool -> set[enum], field
alignment)
* Reuse reward memory when replaying, avoiding spike
* Allow replaying any range in ncli_db benchmark
When applying a block, we'll currently compute a state root for the
state after slot processing but before block processing - this is
unnecessary when a block is being applied because the intermediate state
root is never observed.
This PR reduces the number of database queries for slashing protection
from 5 reads and 1 write to 2 reads and 1 write in the optimistic case.
In the process, it removes user-level support for writing the database
in the version 1 format in order to simplify the code flow, and prevent
code rot. In particular, the v1 format was not covered by any unit tests
and has no advantages over v2. The concrete code to read and write it
remains for now, in particular to support upgrades from v1 to v2.
The branch also removes the use of concepts which doesn't work with
checked exceptions - in particular, this highlights code that both
raises exceptions and returns error codes, which could be cleaned up in
the future.
* Cache internal validator ID
* Rely on unique index to check for trivial duplicate votes
* Combine two surround vote queries into one
* Combine API for checking and registering slashing into single function
The slashing DB is normally not a bottleneck, but may become one with
high attached validator counts.
* Introduce unittest2 and junit reports
* fix XML path
* don't combine multiple CI runs
* fixup
* public combined report also

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
This is a revamp of the attestation pool that cleans up several aspects
of attestation processing as the network grows larger and block space
becomes more precious.
The aim is to better exploit the divide between attestation subnets and
aggregations by keeping the two kinds separate until it's time to either
produce a block or aggregate. This means we're no longer eagerly
combining single-vote attestations, but rather wait until the last
moment, and then try to add singles to all aggregates, including those
coming from the network.
Importantly, the branch improves on poor aggregate quality and poor
attestation packing in cases where block space is running out.
A basic greed scoring mechanism is used to select attestations for
blocks - attestations are added based on how much many new votes they
bring to the table.
* Collect single-vote attestations separately and store these until it's
time to make aggregates
* Create aggregates based on single-vote attestations
* Select _best_ aggregate rather than _first_ aggregate when on
aggregation duty
* Top up all aggregates with singles when it's time make the attestation
cut, thus improving the chances of grabbing the best aggregates out
there
* Improve aggregation test coverage
* Improve bitseq operations
* Simplify aggregate signature creation
* Make attestation cache temporary instead of storing it in attestation
pool - most of the time, blocks are not being produced, no need to keep
the data around
* Remove redundant aggregate storage that was used only for RPC
* Use tables to avoid some linear seeks when looking up attestation data
* Fix long cleanup on large slot jumps
* Avoid some pointers
* Speed up iterating all attestations for a slot (fixes#2490)
* only deserialize attestation and aggregation gossiped signatures once
* re-indent some aggregate checks into block scope
* spelling
* remove debugging assertion
* put part of gossip validation back into block context
* attestation pool test signature loading isn't so unsafe, and exportRaw isn't free
* remove more development doAsserts; don't exportRaw in loops
* Reset cached indices when resetting cache on SSZ read
When deserializing into an existing structure, the cache should be
cleared - goes for json also. Also improve error messages.
* batch attestations
* Fixes (but now need to investigate the chronos 0 .. 4095 crash similar to https://github.com/status-im/nimbus-eth2/issues/1518
* Try to remove the processing loop to no avail :/
* batch aggregates
* use resultsBuffer size for triggering deadline schedule
* pass attestation pool tests
* Introduce async gossip validators. May fix the 4096 bug (reentrancy issue?) (similar to sync unknown blocks #1518)
* Put logging at debug level, add speed info
* remove unnecessary batch info when it is known to be one
* downgrade some logs to trace level
* better comments [skip ci]
* Address most review comments
* only use ref for async proc
* fix exceptions in eth2_network
* update async exceptions in gossip_validation
* eth2_network 2nd pass
* change to sleepAsync
* Update beacon_chain/gossip_processing/batch_validation.nim

* update some v1.1.0 alpha1 to alpha2
* remove unused getDepositMessage overload and move other out of datatypes/base
* bump nim-eth2-scenarios to download v1.1.0-alpha.2 test vectors
* construct object rather than result
Since quite a lot of additional procs were now compiled as generics, this lead to compiler bugs that had
to be worked-around:
* The `Domain` type was renamed to `Eth2Domain` to avoid compilation errors
due to conflicts with `nativesockets.Domain`.
Similarly, `eth2_network.KeyPair` was renamed to `NetKeyPair`.
* A new more robust version of `hexToByteArray` was added to stew
* set upper bound on EpochRef cache
* max 32 EpochRef instances
* less memory waste in BlockRef by removing EpochRef seq that is mostly
unused (~20mb)
* less memory waste in dag block lookup by not keeping an extra copy of
digest (~70mb)
* fix `==` and `$` for Eth2Digest
* remove `ChainDAG.tmpState` (~50mb?)
all in all, this branch cuts mainnet memory usage by ~160-180mb and puts
limits on EpochRef cache usage - where normally it hovered around 950mb
before, it's now sitting at 600-700mb on my machine.
