* move file loading out of timed ncli section to focus benchmark on
deserialization rather than disk loading
* JSON loading fix included in bump, but does not practically happen
since we generally don't load hashlist from JSON
* async batch verification
When batch verification is done, the main thread is blocked reducing
concurrency.
With this PR, the new thread signalling primitive in chronos is used to
offload the full batch verification process to a separate thread
allowing the main threads to continue async operations while the other
threads verify signatures.
Similar to previous behavior, the number of ongoing batch verifications
is capped to prevent runaway resource usage.
In addition to the asynchronous processing, 3 addition changes help
drive throughput:
* A loop is used for batch accumulation: this prevents a stampede of
small batches in eager mode where both the eager and the scheduled batch
runner would pick batches off the queue, prematurely picking "fresh"
batches off the queue
* An additional small wait is introduced for small batches - this helps
create slightly larger batches which make better used of the increased
concurrency
* Up to 2 batches are scheduled to the threadpool during high pressure,
reducing startup latency for the threads
Together, these changes increase attestation verification throughput
under load up to 30%.
* fixup
* Update submodules
* fix blst build issues (and a PIC warning)
* bump

* speed up state/block loading
When loading blocks and states from db/era, we currently redundantly
check their CRC32 - for a state, this costs 50ms of loading time
presently (110mb uncompressed size) on a decent laptop.

data since we store the framed format - also, we're in luck: we blew
past the limit quite some time ago

* Refactor nimbus_signing_node to support Unix signals.

* Add /reload endpoint and implementation.
Fix signData to not cancel `timer`.
Fix validator_pool should clear attachedValidators table.
* Diva protocol enhancement implementation.
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
* Local sim impovements
* Added support for running Capella and EIP-4844 simulations
by downloading the correct version of Geth.
* Added support for using Nimbus remote signer and Web3Signer.
Use 2 out of 3 threshold signing configuration in the mainnet
configuration and regular remote signing in the minimal one.
* The local testnet simulation can now use a payload builder.
This is currently not activated in CI due to lack of automated
procedures for installing third-party relays or builders.
You are adviced to use mergemock for now, but for most realistic
results, we can create a simple builder based on the nimbus-eth1
codebase that will be able to propose transactions from the regular
network mempool.
* Start the simulation from a merged state. This would allow us
to start removing pre-merge functionality such as the gossip
subsciption logic. The commit also removes the merge-forcing
hack installed after the TTD removal.
* Consolidate all the tools used in the local simulation into a
single `ncli_testnet` binary.
Other changes:
Renamed the `EIP_4844_FORK_*` config constants to `DENEB_FORK_*` as
this matches the latest spec and it's already used in the official
Sepolia config.
* Working Makefile targets for Capella devnet2
make capella-devnet-2
make clean-capella-devnet-2
You'll need to have https://github.com/tmuxinator/tmuxinator installed.
It's available as a regular package in most Linux distributions or through
Nix or Brew on macOS.
This commit also fixes the initial hang in the Eth1 monitor in the "find
TTD block" procedure through a fix to the network metadata files which
hasn't been upstreamed yet.
Other changes:
* Disabled Geth snap sync in the simulation
When all Geth nodes are configured to run with snap sync enabled, they all
start snap sync after the first forkchoiceUpdated which causes the BNs to
skip validator duties because the EL is syncing. The snap sync never completes
due to poor connectivity between the Geth nodes in the simulation.
Introduce (optional) pruning of historical data - a pruned node will
continue to answer queries for historical data up to
`MIN_EPOCHS_FOR_BLOCK_REQUESTS` epochs, or roughly 5 months, capping
typical database usage at around 60-70gb.
To enable pruning, add `--history=prune` to the command line - on the
first start, old data will be cleared (which may take a while) - after
that, data is pruned continuously.
When pruning an existing database, the database will not shrink -
instead, the freed space is recycled as the node continues to run - to
free up space, perform a trusted node sync with a fresh database.
When switching on archive mode in a pruned node, history is retained
from that point onwards.
History pruning is scheduled to be enabled by default in a future
release.
In this PR, `minimal` mode from #4419 is not implemented meaning
retention periods for states and blocks are always the same - depending
on user demand, a future PR may implement `minimal` as well.
Since the sync committee duties are no longer updated on every slot
and previously the sync committee aggregators selection proofs were
generated during the duties update, this now resulted in the client
using stale selection proofs (they must be generated at each slot).
The fix consists of moving the selection proof generation logic in
a different function which is properly executed on each slot.
Other changes:
* The logtrace tool has been enhanced with a framework for adding
new simpler log aggregation and analysis algorithms.
The default CI testnet simulation will now ensure that the blocks
in the network have reasonable sync committee participation.
To further tighten Nimbus against spam, this PR introduces a global
quota for block requests (shared between peers) as well as a general
per-peer request limit that applies to all libp2p requests.
* apply request quota before decoding message
* for high-bandwidth requests (blocks), apply a shared global quota
which helps manage bandwidth for high-peer setups
* add metrics
When connecting to hosts on shared IP/Port using TLS, SNI must be sent
to allow the remote server to provide the correct TLS certificate.
Bump the `nim-json-rpc` and `nim-websock` dependencies to send SNI ext.
`news` has a few open issues that are not present in `nim-websock`:
1. There is a 1 second delay between each MB of sent data.
2. Cancelling an ongoing `send` makes the entire WebSocket unusable.
3. Control packets do not have priority over ongoing message frames.
Using `news`, there are quite a few of these messages in Geth:
```
Previously seen beacon client is offline. Please ensure it is
operational to follow the chain!
```
It may take quite some time to reconnect when this happens.
Using `nim-websock`, this message still occurs because `eth1_monitor`
reconnects the EL connection when no new blocks occurred for 5 minutes,
but reconnecting is quick and the message is rarer.
When calling `newPayload` on a >1MB payload (can happen post-merge),
`news` splits up that payload into 1MB chunks. The chunks are each sent
individually, though, with `await` in-between. This means that when we
send concurrent `forkChoiceUpdated` calls, that those may end up getting
in-between the `newPayload` chunks, leading to invalid data being sent.
The EL then returns an error message with a `null` `id` entry (as it
could not read the request `id` due to the mangling) and disconnects.
A PR has been submitted to fix this in `news`, and merged into `status`
branch early as this fix is critical for reliable post-merge operation:
https://github.com/Tormund/news/pull/22
* Re-enabled requireAllFields after a fix in nim-json-serialization
The problem was that `Option[T]` fields were not treated as optional
when requireAllFields is set to true. This is now fixed in NJS.
* Add makefile targets for recreating the Jenkins simulation runs
* Fix a discrepancy with the REST spec
Whether new blocks/attestations/etc are produced internally or received
via REST, their journey through the node is the same - to ensure that
they get the same treatment (logging, metrics, processing), this PR
moves the routing to a dedicated module and fixes several small
differences that existed before.
* `xxxValidator` -> `processMessageName` - the processor also was adding
messages to pools, so we want the name to reflect that action
* add missing "sent" metrics for some messages
* document ignore policy better - already-seen messages are not actaully
rebroadcast by libp2p
* skip redundant signature checks for internal validators consistently
This updates `nim-ssz-serialization` to
`3db6cc0f282708aca6c290914488edd832971d61`.
Notable changes:
- Use `uint64` for `GeneralizedIndex`
- Add support for building merkle multiproofs
* Initial commit
* Make `events` API spec compliant.
* Add `Eth-Consensus-Version` in responses.
* Bump chronos to get redirect with headers working.
* Add `is_optimistic` field and handling to syncing RestSyncInfo.
* SSZ `[]` -> `mitem`
* `[]` -> `item`
immutable access via mutable instance cannot rely on template
overloading, and `[]` cannot be a `func` because of special seq handling
in compiler.
Other fixes:
* Fix bit rot in the `make prater-dev-deposit` target.
* Correct content-type in the responses of the Nimbus signing node
* Invalid JSON payload was being sent in the web3signer requests
This PR makes the necessary adjustments to deal with the revamped snappy
API.
In practical terms for nimbus-eth2, there are performance increases to
gossip processing, database reading and writing as well as era file
processing. Exporting `.era` files for example, a snappy-heavy
operation, almost halves in total processing time:
Pre:
```
Average, StdDev, Min, Max, Samples, Test
39.088, 8.735, 23.619, 53.301, 50, tState
237.079, 46.692, 165.620, 355.481, 49, tBlocks
```
Post:
```
All time are ms
Average, StdDev, Min, Max, Samples, Test
25.350, 5.303, 15.351, 41.856, 50, tState
141.238, 24.164, 99.990, 199.329, 49, tBlocks
```
Some upstream repos still need fixes, but this gets us close enough that
style hints can be enabled by default.
In general, "canonical" spellings are preferred even if they violate
nep-1 - this applies in particular to spec-related stuff like
`genesis_validators_root` which appears throughout the codebase.
rocksdb was never actually used in nimbus-eth2 and existed only to satisfy nim-eth dependencies for test running - these have since moved to nimbus-eth1.
* bump nim-eth
`.era` files and Req/Resp protocols use framed formats - aligning the
database with these makes for less recompression work overall as gossip
is sent only once while req/resp repeats (potentially) - this also
allows efficient pruning-to-era where snappy-recompression is the major
cycle thief.
Changes in nim-eth relevant to nimbus-eth2:
- Style fixes according to --styleCheck:usages (#452)
- Add discoveryv5 session metrics (#454)
- Don’t use exceptions for enr get call (#453)
- Add DiscoveryConfig to tune routing table ip limits and bitPerHops
- More --styleCheck fixes for discoveryv5 and eth/common (#473)
The added options work in opt-in fashion. If they are not specified,
the server will respond to all requests as if the CORS specification
doesn't exist. This will result in errors in CORS-enabled clients.
Please note that future versions may support more than one allowed
origin. The option names will stay the same, but the user will be
able to repeat them on the command line (similar to other options
such as --web3-url).
To be documented in the guide in a separate PR.
* Fix a resource leak introduced in https://github.com/status-im/nimbus-eth2/pull/3279
* Don't restart the Eth1 syncing proggress from scratch in case of
monitor failures during Eth2 syncing.
* Switch to the primary operator as soon as it is back online.
* Log the web3 credentials in fewer places
Other changes:
The 'web3 test' command has been enhanced to obtain and print more
data regarding the selected provider.
* Store finalized block roots in database (3s startup)
When the chain has finalized a checkpoint, the history from that point
onwards becomes linear - this is exploited in `.era` files to allow
constant-time by-slot lookups.
In the database, we can do the same by storing finalized block roots in
a simple sparse table indexed by slot, bringing the two representations
closer to each other in terms of conceptual layout and performance.
Doing so has a number of interesting effects:
* mainnet startup time is improved 3-5x (3s on my laptop)
* the _first_ startup might take slightly longer as the new index is
being built - ~10s on the same laptop
* we no longer rely on the beacon block summaries to load the full dag -
this is a lot faster because we no longer have to look up each block by
parent root
* a collateral benefit is that we no longer need to load the full
summaries table into memory - we get the RSS benefits of #3164 without
the CPU hit.
Other random stuff:
* simplify forky block generics
* fix withManyWrites multiple evaluation
* fix validator key cache not being updated properly in chaindag
read-only mode
* drop pre-altair summaries from `kvstore`
* recreate missing summaries from altair+ blocks as well (in case
database has lost some to an involuntary restart)
* print database startup timings in chaindag load log
* avoid allocating superfluos state at startup
* use a recursive sql query to load the summaries of the unfinalized
blocks
* initial support for minification and new interchange tests. Removal of v1 and v1 migration.
* Synthetic attestations: SQLite3 requires one statement/query per prepared statement
* Fix DB import interrupted if no attestation was found
* Skip test relying on undocumented test behavior (https://github.com/eth-clients/slashing-protection-interchange-tests/pull/12#issuecomment-1011158701)
* Skip test relying on unclear minification behavior:
creating an invalid minified attestation with source > target or setting target = max(source, target)
* remove DB v1 and update submodule
* Apply suggestions from code review

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

This still doesn't work properly because it leads to a change in
the "eth" ENR field of the client. Since the client uses the value
of this field to look for other nodes on the network, the change
effectively prevents us from finding peers.

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

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

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
* update to Altair as of v1.1.0-alpha.7
* introduce Altair types into attestation pool
* avoid allocating/copying pubkeys excessively in get_next_sync_committee()
* write uncompressed validator keys to database
Loading 150k+ validator keys on startup in compressed format takes a lot
of time - better store them in uncompressed format which makes behaviour
just after startup faster / more predictable.
* refactor cached validator key access
* fix isomorphic cast to work with non-var instances
* remove cooked pubkey cache - directly use database cache in chaindag
as well (one less cache to keep in sync)
* bump blscurve, introduce loadValid for known-to-be-valid keys
The V1 table structure shows great improvements in performance, but if
there's an old `kvstore` without rowid:s, these benefits are nullified:
reorgs during writes and deletes remain expensive (even if the
degradation is reduced somewhat).
This PR creates the tables in a new file instead, and uses the old file
as a read-only store - this has several interesting properties:
* the old database is left completely untouched - this guarantees that
downgrades work smooth (they'll only need to resync their missing
portions)
* starting sync after this PR means only a v1 database is created
* v0 databases stick around - no migration is performed (for now)
Future PR:s can introduce migration of the data from one database to
another - a simply copy will take hours which is downtime we want to
avoid - at that point, it might make sense to migrate straight to era
files instead.
* Error when specifying an invalid --data-dir (or --validator-dir)
* Error when entering an invalid validator public key (e.g. invalid hex value)
* Warning when attempting to export a validator not present in the local database
Some unnecessary remains of the v1 mode has been removed as well
* Revert "Revert "Upgrade database schema" (#2570)"
This reverts commit 6057c2ffb4.
* ssz: fix loading empty lists into existing instances
Not a problem earlier because we didn't reuse instances
* bump nim-eth
* bump nim-web3
This is a minimal performance hotfix for the kvstore table, such that
new databases get a kvstore table with rowid, fixing the most urgent
performance problem we have with pruning.
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)
* Introduce unittest2 and junit reports
* fix XML path
* don't combine multiple CI runs
* fixup
* public combined report also
