Backfilling is the process of downloading historical blocks via P2P that
are required to fulfill `GetBlocksByRange` duties - this happens during
both trusted node and finalized checkpoint syncs.
In particular, backfilling happens after syncing to head, such that
attestation work can start as soon as possible.
* Fix SyncQueue initialization procedure.
Remove usage of `awaitne`.
Add cancellation support.
Remove unneeded `sleepAsync()` if peer's head is older than needed.
Add `direction` field to all logs.
Fix syncmanager wedge issue.
Add proper resource cleaning procedure on backward sync finish.

The new format is based on compressed CSV files in two channels:
* Detailed per-epoch data
* Aggregated "daily" summaries
The use of append-only CSV file speeds up significantly the epoch
processing speed during data generation. The use of compression
results in smaller storage requirements overall. The use of the
aggregated files has a very minor cost in both CPU and storage,
but leads to near interactive speed for report generation.
Other changes:
- Implemented support for graceful shut downs to avoid corrupting
the saved files.
- Fixed a memory leak caused by lacking `StateCache` clean up on each
iteration.
- Addressed review comments
- Moved the rewards and penalties calculation code in a separate module
Required invasive changes to existing modules:
- The `data` field of the `KeyedBlockRef` type is made public to be used
by the validator rewards monitor's Chain DAG update procedure.
- The `getForkedBlock` procedure from the `blockchain_dag.nim` module
is made public to be used by the validator rewards monitor's Chain DAG
update procedure.
This is an alternative take on https://github.com/status-im/nimbus-eth2/pull/3107
that aims for more minimal interventions in the spec modules at the expense of
duplicating more of the spec logic in ncli_db.
Using the wrong type here causes requests to fail due to the overly
zealous parameter validation - the failure is harmless in the current
duty subscription model, but would have caused more serious failures
down the line.
* Trusted node sync
Trusted node sync, aka checkpoint sync, allows syncing tyhe chain from a
trusted node instead of relying on a full sync from genesis.
Features include:
* sync from any slot, including the latest finalized slot
* backfill blocks either from the REST api (default) or p2p (#3263)
Future improvements:
* top up blocks between head in database and some other node - this
makes for an efficient backup tool
* recreate historical state to enable historical queries
* fixes
* load genesis from network metadata
* check checkpoint block root against state
* fix invalid block root in rest json decoding
* odds and ends
* retry looking for epoch-boundary checkpoint blocks
When syncing, we show how much of the sync has completed - with
checkpoint sync, the syncing does not always go from slot 0 to head, but
rather can start in the middle.
To show a consistent `%` between restarts, we introduce the concept of a
pivot point, such that if I sync 10% of the chain, then restart the
client, it picks up at 10% (instead of counting from 0).
What it looks like:
```
INF ... sync="01d12h41m (15.96%) 13.5158slots/s (QDDQDDQQDP:339018)" ...
```
Time in the beacon chain is expressed relative to the genesis time -
this PR creates a `beacon_time` module that collects helpers and
utilities for dealing the time units - the new module does not deal with
actual wall time (that's remains in `beacon_clock`).
Collecting the time related stuff in one place makes it easier to find,
avoids some circular imports and allows more easily identifying the code
actually needs wall time to operate.
* move genesis-time-related functionality into `spec/beacon_time`
* avoid using `chronos.Duration` for time differences - it does not
support negative values (such as when something happens earlier than it
should)
* saturate conversions between `FAR_FUTURE_XXX`, so as to avoid
overflows
* fix delay reporting in validator client so it uses the expected
deadline of the slot, not "closest wall slot"
* simplify looping over the slots of an epoch
* `compute_start_slot_at_epoch` -> `start_slot`
* `compute_epoch_at_slot` -> `epoch`
A follow-up PR will (likely) introduce saturating arithmetic for the
time units - this is merely code moves, renames and fixing of small
bugs.
* Harden CommitteeIndex, SubnetId, SyncSubcommitteeIndex
Harden the use of `CommitteeIndex` et al to prevent future issues by
using a distinct type, then validating before use in several cases -
datatypes in spec are kept simple though so that invalid data still can
be read.
* fix invalid epoch used in REST
`/eth/v1/beacon/states/{state_id}/committees` committee length (could
return invalid data)
* normalize some variable names
* normalize committee index loops
* fix `RestAttesterDuty` to use `uint64` for `validator_committee_index`
* validate `CommitteeIndex` on ingress in REST API
* update rest rules with stricter parsing
* better REST serializers
* save lots of memory by not using `zip` ...at least a few bytes!
* REST cleanups
* reject out-of-range committee requests
* print all hex values as lower-case
* allow requesting state information by head state root
* turn `DomainType` into array (follow spec)
* `uint_to_bytesXX` -> `uint_to_bytes` (follow spec)
* fix wrong dependent root in `/eth/v1/validator/duties/proposer/`
* update documentation - `--subscribe-all-subnets` is no longer needed
when using the REST interface with validator clients
* more fixes
* common helpers for dependent block
* remove test rules obsoleted by more strict epoch tests
* fix trailing commas
* Update docs/the_nimbus_book/src/rest-api.md
* Update docs/the_nimbus_book/src/rest-api.md

Overhaul of era files, including documentation and reference
implementations
* store blocks, then state, then slot indices for easy lookup at low
cost
* document era file rationale

* use common forked block/state reader in REST API
* fix stack overflows in REST JSON decoder
* fix invalid serialization of `justification_bits` in
`/eth/v1/debug/beacon/states` and `/eth/v2/debug/beacon/states`

standard says - `/api` was added early on based on an example "base url"
in the spec that has been removed since
* expose Nimbus REST extensions via `/nimbus` in addition to
`/api/nimbus` to stay consistent with `/eth`
* fix invalid state root when reading states via REST
* fix recursive imports in `spec/ssz_codec`
* remove usages of `serialization.useCustomSerialization` - fickle
With checkpoint sync in particular, and state pruning in the future,
loading states or state-dependent data may fail. This PR adjusts the
code to allow this to be handled gracefully.
In particular, the new availability assumption is that states are always
available for the finalized checkpoint and newer, but may fail for
anything older.
The `tail` remains the point where state loading de-facto fails, meaning
that between the tail and the finalized checkpoint, we can still get
historical data (but code should be prepared to handle this as an
error).
However, to harden the code against long replays, several operations
which are assumed to work only with non-final data (such as gossip
verification and validator duties) now limit their search horizon to
post-finalized data.
* harden several state-dependent operations by logging an error instead
of introducing a panic when state loading fails
* `withState` -> `withUpdatedState` to differentiate from the other
`withState`
* `updateStateData` can now fail if no state is found in database - it
is also hardened against excessively long replays
* `getEpochRef` can now fail when replay fails
* reject blocks with invalid target root - they would be ignored
previously
* fix recursion bug in `isProposed`
* Fix REST some rest call signatures and implement a simple API benchmark tool
* Implement #3129 (Optimized history traversals in the REST API)
Other notable changes:
The `updateStateData` procedure in the `blockchain_dag.nim` module is
optimized to not rewind down to the last snapshot state saved in the
database if the supplied input state can be used as a starting point
instead.
* Disallow await in withStateForBlockSlot
* Tune getLowSubnets
* Also aim for dHigh peers in gossipsub
* Apply suggestions from code review

With the right sequence of events (for example a REST request or a
validation), it can happen that the first traversal across a state
checkpoint boundary is done without storing that state on disk - this
causes problens when replaying states, because now states may be missing
from the database.
Here, we simply avoid using the caches when advancing a state that will
go into the database, ensuring that the information lost during caching
always is permanently stored.
* fix recursion bug in `isProposed`
A novel optimisation for attestation and sync committee message
validation: when batching, we look for signatures of the same message
and aggregate these before batch-validating: this results in up to 60%
fewer signature verifications on a busy server, leading to a significant
reduction in CPU usage.
* increase batch size slightly which helps finding more aggregates
* add metrics for batch verification efficiency
* use simple `blsVerify` when there is only one signature to verify in
the batch, avoiding the RNG
* use v1.1.6 test vectors; use BeaconTime instead of Slot in fork choice
* tick through every slot at least once
* use div INTERVALS_PER_SLOT and use precomputed constants of them
* use correct (even if numerically equal) constant
Introduced in #3171, it turns out we can just follow the block headers
to achieve the same effect
* leaves the constant in the code so as to avoid confusion when reading
database that had the constant written (such as the fleet nodes and
other unstable users)
Validator monitoring based on and mostly compatible with the
implementation in Lighthouse - tracks additional logs and metrics for
specified validators so as to stay on top on performance.
The implementation works more or less the following way:
* Validator pubkeys are singled out for monitoring - these can be
running on the node or not
* For every action that the validator takes, we record steps in the
process such as messages being seen on the network or published in the
API
* When the dust settles at the end of an epoch, we report the
information from one epoch before that, which coincides with the
balances being updated - this is a tradeoff between being correct
(waiting for finalization) and providing relevant information in a
timely manner)
* SyncManager cleanups for backfill support
Cleanups, fixes and simplifications, in anticipation of backfill support
for the `SyncManager`:
* reformat sync progress indicator to show time left and % done more
prominently:
* old: `sync="sPssPsssss:2:2.4229:00h57m (2706898)"`
* new: `sync="14d12h31m (0.52%) 1.1378slots/s (wQQQQQDDQQ:1287520)"`
* reset average speed when going out of sync
* pass all block errors to sync manager, including duplicate/unviable
* penalize peers for reporting a head block that is outside of our
expected wall clock time (they're likely on a different network or
trying to disrupt sync)
* remove `SyncFailureKind` (unused)
* remove `inRange` (unused)
* add `Q` for sync queue requests that are in the `SyncQueue` but not
yet in the `BlockProcessor` queue
* update last slot in `SyncQueue` after getting peer status
* fix race condition between `wakeupWaiters` and `resetWait`, where
workers would not be correctly reset if block verification returned a
completed future without event loop
* log syncmanager direction
* Fix ordering issue.
Some of the requests size of which are not equal to `chunkSize` could be processed in wrong order which could lead to sync process freezes.

PBKDF2 based keystore files are required to have `dklen >= 32`.
This patch ensures that keystores not fulfilling that requirement
are properly rejected.
In the ChainDAG, 3 block pointers are kept: genesis, tail and head. This
PR adds one more block pointer: the backfill block which represents the
block that has been backfilled so far.
When doing a checkpoint sync, a random block is given as starting point
- this is the tail block, and we require that the tail block has a
corresponding state.
When backfilling, we end up with blocks without corresponding states,
hence we cannot use `tail` as a backfill pointer - there is no state.
Nonetheless, we need to keep track of where we are in the backfill
process between restarts, such that we can answer GetBeaconBlocksByRange
requests.
This PR adds the basic support for backfill handling - it needs to be
integrated with backfill sync, and the REST API needs to be adjusted to
take advantage of the new backfilled blocks when responding to certain
requests.
Future work will also enable moving the tail in either direction:
* pruning means moving the tail forward in time and removing states
* backwards means recreating past states from genesis, such that
intermediate states are recreated step by step all the way to the tail -
at that point, tail, genesis and backfill will match up.
* backfilling is done when backfill != genesis - later, this will be the
WSS checkpoint instead
There are multiple copies of `bitseqs` (`nim-stew`, `nim-eth`, and
`nim-ssz-serialization`). To avoid confusion, this patch removes the
final remaining reference of a non-`nim-ssz-serialization` copy.
Makes `readSszForkedTrustedSignedBeaconBlock` consistent with
`readSszForkedHashedBeaconState`, adjusting the length check
to verify the same type that is used for length computation,
and using the same formatting.
* BlockId reform
Introduce `BlockId` that helps track a root/slot pair - this prepares
the codebase for backfilling and handling out-of-dag blocks
* move block dag code to separate module
* fix finalised state root in REST event stream
* fix finalised head computation on head update, when starting from
checkpoint
* clean up chaindag init
* revert `epochAncestor` change in introduced in #3144 that would return
an epoch ancestor from the canoncial history instead of the given
history, causing `EpochRef` keys to point to the wrong block
* batch-verify sync messages for a small perf boost
Generally reuses the same structure as attestation and aggregate
verification
* normalize `signatures` and `signature_batch` to use the same pattern
of verification
* normalize parameter names, order etc for signature stuff in general
* avoid calling `blsSign` directly - instead, go through `signatures`
consistently
This removes some dead code from `getSubcommitteePositionsAux` which is
no longer needed since the introduction of `SyncCommitteeCache`.
This also cleans up some formatting, uses `let` instead of `var` where
possible, and uses implicit `pairs` in one case for consistency.
* Introduce slot->BlockRef mapping for finalized chain
The finalized chain is linear, thus we can use a seq to lookup blocks by
slot number.
Here, we introduce such a seq, even though in the future, it should
likely be backed by a database structure instead, or, more likely, a
flat era file with a flat lookup index.
This dramatically speeds up requests by slot, such as those coming from
the REST interface or GetBlocksByRange, as these are currently served by
a linear iteration from head.
* fix REST block requests to not return blocks from an earlier slot when
the given slot is empty
* fix StateId interpretation such that it doesn't treat state roots as
block roots
* don't load full block from database just to return its root
This PR fixes two issues with block publishing:
* Gossip-valid blocks are published before integrating them into the
chain, giving broadcasting a head start, both for rest block and
* Outright invalid blocks from the API that could lead to the descoring
of the node are no longer broadcast
Bonus:
* remove undocumented and duplicated `post_v1_validator_block` JSON-RPC
call
* move quarantine outside of chaindag
The quarantine has been part of the ChainDAG for the longest time, but
this design has a few issues:
* the function in which blocks are verified and added to the dag becomes
reentrant and therefore difficult to reason about - we're currently
using a stateful flag to work around it
* quarantined blocks bypass the processing queue leading to a processing
stampede
* the quarantine flow is unsuitable for orphaned attestations - these
should also should be quarantined eventually
Instead of processing the quarantine inside ChainDAG, this PR moves
re-queueing to `block_processor` which already is responsible for
dealing with follow-up work when a block is added to the dag
This sets the stage for keeping attestations in the quarantine as well.
Also:
* make `BlockError` `{.pure.}`
* avoid use of `ValidationResult` in block clearance (that's for gossip)
* Add some indicators to help fixing issue.
* Bump presto to help debugging.
* Fix compilation problems in presto.
* Fix SIGSEGV.
* Bump latest changes in chronos and presto.
Fix rare cases in validator_client.
* Use proper commits for chronos and presto.
Used during initial development of the spec, `nbench` has fallen behind
and by and large been superceded by `block_sim`, `state_sim` and
`ncli_db bench`.
Some `LightClientUpdate` documentation of the spec is meant to span
multiple fields but was attached to a single, incorrect field in Nimbus.
This patch moves affected documentation to correct locations.
This allows `blockchain_dag`'s `withState` template to be called more
than once in a single function. This led to a compilation error before
because the injected variables and functions shared the same scope.
Validator clients such as Vouch can be configured to work with multiple
beacon nodes simultaneously. In this configuration, the validator client
will try to broadcast the gossip messages through each of the connected
beacon nodes which may lead to a situation where some of the nodes see a
message arriving from the network before it arrives through the REST API.
This should not be considered an error and the beacon node should still
broadcast the message as the intented purpose of the Vouch strategy is
to ensure that the message will reach as many peers as possible.
Turning uncompressed pubkeys into cooked ones is fast, but unnecessary -
this should avoid a little work for every signature validation we do by
pre-loading them at startup.
* add EF fork choice tests to CI
* checkpoints
* compilation fixes and add test to preset dependent suite
* support longpaths on Windows CI
* skip minimal tests (long paths issue + impl detals tested)
* fix stackoverflow on some platforms
* rebase on top of https://github.com/status-im/nimbus-eth2/pull/3054
* fix stack usage
Renames and cleanups split out from the validator monitoring branch, so
as to reduce conflict area vs other PR:s
* add constants for expected message timing
* name validators after the messages they validate, mostly, to make
grepping easier
* unify field naming of EpochInfo across forks to make cross-fork code
easier
Currently, we don't have a good answer to the question "are we synced
yet" - the sync manager syncs based on the peers it's connected to, but
just because some peer looks like it should be synced from doesn't mean
we're out of sync.
Instead, we use a very silly time-based heuristic - the problem with
that is that the network can go into a rut where nobody produces blocks
- better heuristics would be needed here, but in the meantime, a command
line option can get us out of a tight spot - this PR places such an
option in the client, in the unlikely event it should be needed (most
likely in a testnet).
* ncli_db: add putState, putBlock
These tools allow modifying an existing nimbus database for the purpose
of recovery or reorg, moving the head, tail and genesis to arbitrary
points.
* remove potentially expensive `putState` in `BeaconStateDB`
* introduce `latest_block_root` which computes the root of the latest
applied block from the `latest_block_header` field (instead of passing
it in separately)
* avoid some unnecessary BeaconState copies during init
* discover https://github.com/nim-lang/Nim/issues/19094
* prefer `HashedBeaconState` in a few places to avoid recomputing state
root
* fetch latest block root from state when creating blocks
* harden `get_beacon_proposer_index` against invalid slots and document
* move random spec function tests to `test_spec.nim`
* avoid unnecessary state root computation before block proposal
* Support starting from altair
* hide `finalized-checkpoint-` - they are incomplete and usage may cause
crashes
* remove genesis detection code (broken, obsolete)
* enable starting ChainDAG from altair checkpoints - this is a
prerequisite for checkpoint sync (TODO: backfill)
* tighten checkpoint state conditions
* show error when starting from checkpoint with existing database (not
supported)
* print rest-compatible JSON in ncli/state_sim
* altair/merge support in ncli
* more altair/merge support in ncli_db
* pre-load header to speed up loading
* fix forked block decoding
* Reduce the logging-related breaking changes
* Don't disable the stdout log when the `--log-file` option is used
* Rename `--log-stdout` to `--log-format` and hide it
* Deprecate the `--log-file` option
* Address review comments in #3057
* reorder imports in rest_utils
maybe this will help with the mysterious serialization issues

This is a temporary revert of the new logic introduced in
d6cd1cd46c, because it leads
to a memory leak in the Eth1Monitor caused by the lack of
pruning of the Eth1Chain when the validator duties are not
executed.
According to the spec, this call should return the positions of
the specified validators within the sync committee. The existing
code was instead returning the indices of the sync sub-committees
where the validator is a member.
* fix stack overflow crash in REST/debug/getStateV2
* introduce `ForkyXxx` for generic type matching of `Xxx` across
branches (SomeHashedBeaconState -> ForkyHashedBeaconState et al) -
`Some` is already used for other types of type classes
* consolidate function naming in BeaconChainDB, use some generics
* import `forks.nim` from other spec modules and move `Forked*` helpers
around to resolve circular imports
* remove `ForkedBeaconState`, use `ForkedHashedBeaconState` throughout
(less data shuffling between the types)
* fix several cases of states being stored on stack in tests, causing
random failures on some platforms
* remove reading json support from ncli - this should be ported to the
rest json reading instead (doesn't currently work because stack sizes)
The sync committee period used to be a plain `uint64`. With the light
client sync relying more heavily on them, it makes sense to introduce
a proper type for them, similar to how they are already used for `Slot`
and `Epoch`. This introduces such a `SyncCommitteePeriod` type.
Furthermore, some usage code dealing with those periods is cleaned up.
So far, the REST config response did not include all spec constants.
The spec for `/eth/v1/config/spec` defines that the response should
include constants for all hard forks known by the beacon node. This
patch extends the corresponding response to include more constants.
* Logging and startup improvements
Color support for released binaries!
* startup scripts no longer log to file by default - this only affects
source builds - released binaries don't support file logging
* add --log-stdout option to control logging to stdout (colors, json)
* detect tty:s vs redirected logs and log accordingly
* add option to disable log colors at runtime
* simplify several "common" logs, showing the most important information
earlier and more clearly
* remove line numbers / file information / tid - these take up space and
are of little use to end users
* still enabled in debug builds and tools
* remove `testnet_servers_image` compile-time option
* server images, released binaries and compile-from-source now offer
the same behaviour and features
* fixes https://github.com/status-im/nimbus-eth2/issues/2326
* fixes https://github.com/status-im/nimbus-eth2/issues/1794
* remove instanteneous block speed from sync message, keeping only
average

The validator client was only able to connect to beacon nodes exposing
the exact same set of spec constants that are locally known via their
config/spec REST API. However, that set of spec constants is dynamic.
As the validator client only requires a subset of relevant constants,
this may lead to compatible specs being rejected. This patch widens the
allowed specs by only verifying that the required set of constants are
present in the spec response, ignoring any spec constants that are not
locally known, and ignoring missing spec constants that are locally
known but not included by the remote beacon node when not relevant for
operation of the validator client.
Currently, `ElemType` can only be called on `HashArray`, `HashList` and
`List` types when they are first assigned to a variable called `T`. The
templates have been adjusted so that different variable names may be
used. The templates can now also be applied to in-line computed types,
e.g., `ElemType(typeof(x))`.
* `SyncCommitteeIndex` -> `SyncSubcommitteeIndex`
* `syncCommitteePeriod` -> `sync_committee_period` (spec spelling)
* tighten period comparisons
* fix assert when validating committee message with non-altair state in
REST api
There was a cyrillic T in some big-endian specific code that broke the
compilation on such platforms. This replaces that T with an ASCII T to
fix the build.
* register vc duties with subnet tracker
* fix activation logging during startup
* cache slot signature to avoid duplicate signature work
* schedule aggregation duties one slot at a time to avoid CPU spike at
each epoch
* lower aggregation subnet pre-subscription time to 4 slots (lowers
bandwidth and CPU usage)
* update stability subnets in ENR on startup
* log gossip state
* perform gossip subscriptions just before the next slot starts
* document stuff
* add random include
* don't overwrite subscription state when not subscribed
* log target gossip state
* updating gossip status once is enough
* add test
* remove syncQueueLen - this one is not updated at the end of the sync
and may cause gossip to disconnect itself completely - use a simple head

* fix gossip disconnection - if in hysteresis, node.gossipState will be
set to disabled even though we don't disable topic subscriptions

* Initial commit.
* Fix path.
* Add validator keys to indices cache mechanism.
Move syncComitteeParticipants to common place.
* Fix sync participants order issue.
* Fix error code when state could not be found.
Refactor `state/validators` to use keysToIndices mechanism.
* Fix RestValidatorIndex to ValidatorIndex conversion TODOs.
* Address review comments.
* Fix REST test rules.
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
