When blocks and attestations arrive, they are SSZ-decoded twice: once
for validation and once for processing. This branch enqueues the decoded
block directly for processing, avoiding the second, slow
deserialization.
* move processing of blocks and attestations to queue
* ...and out from beacon_node
* split attestation processing into attestations and aggregates
* also updates metrics
* clean up logging to better follow the lifetime of gossip: arrival,
validation and processing
* drop attestations and aggregates if there are too many
* try to prioritise blocks and aggregates before single-validator
attestations
* evaluate block attestations under the epochref of the block - this is
what the state transition function does
* avoid copying attestation seq unnecessarily
* avoid unnecessary hashset for unslashed indices
* don't sort shuffled_validator_indices, just get them directly with
iteration
* grab full epoch of proposer indices while we have the data available -
they'll get cached and reused
* avoid computing active validator set when not used for logging
* collect all epochrefs in specific blocks to make them easier to find
and to avoid lots of small seqs
* reuse validator key databases more aggressively by comparing keys
* make state cache available from within `withState`
* make epochRef available from within onBlockAdded callback
* integrate getEpochInfo into block resolution and epoch ref logic such
that epochrefs are created when blocks are added to pool or lazily when
needed by a getEpochRef
* fill state cache better from EpochRef, speeding up replay and
validation
* store epochRef in specific blocks to make them easier to find and
reuse
* fix database corruption when state is saved while replaying quarantine
* replay slots fully from block pool before processing state
* compare bls values more smartly
* store epoch state without block applied in database - it's recommended
to resync the node!
this branch will drastically speed up processing in times of long
non-finality, as well as cut memory usage by 10x during the recent
medalla madness.
* add attestation processing queue so attestations don't get processed
too early
* rework justified slot delay to match spec / lighthouse better
* keep less state in fork choice
* request epochref less
* run logtrace in finalization CI
* use specified DATA_DIR rather than assuming default
* convert rest of hardcoded local_testnet_data references
* logtrace asr needs DEBUG-level logs
* clean up some shell (not) quoting issues
* add --enable-logtrace argument to launch_local_testnet
* scan for all available logfiles
* remove specific filename references
* update v0.11.3 spec ref to v0.12.2
* Bump BLSCurve
* Use unified aggregation API
* use new blscurve with unified aggregate API
* bump
* fix toRaw
* replace state_sim combine with AggregateSignature
* Fix 32-bit
* Fix 32-bit for real and test deactivating ccache for fno-tree-lopp-vectorize flag
* change compilation switches to narrow down Linux issue
* Use -fno-tree-vectorize to disable both tree-loop-vectorize and tree-slp-vectorize
* blscurve now disables both Loop and SLP vectorization
* Add tests for the miracl/milagro fallback
* Travis has max log size of 4MB
* Test with Miracl in the finalization test
* fix state_sim log level
* Coment out the slow fallback tests
* fix invalid state root being written to database
When rewinding state data, the wrong block reference would be used when
saving the state root - this would cause state loading to fail by
loading a different state than expected, preventing blocks to be
applied.
* refactor state loading and saving to consistently use and set
StateData block
* avoid rollback when state is missing from database (as opposed to
being partially overwritten and therefore in need of rollback)
* don't store state roots for empty slots - previously, these were used
as a cache to avoid recalculating them in state transition, but this has
been superceded by hash tree root caching
* don't attempt loading states / state roots for non-epoch slots, these
are not saved to the database
* simplify rewinder and clean up funcitions after caches have been
reworked
* fix chaindag logscope
* add database reload metric
* re-enable clearance epoch tests
* names
* initial dynamic subscribe/unsubscribe for attestations to/from subnets
* implement random stability subnet and clean up
* switch from HashSet[uint64] to set[uint8]
* refactor subnet logic out from beacon_node and actual (un)subscribing
* only try to subscribe to marginally different subnets
* add assertions
* maintain ENR subnets
* assert that beacon_node and eth2_network have consistent view of subscribed subnets
* disable actual cycling
* Eliminate possibilities for range errors and overflows
* Handle more properly invalid requests for furute slots
* Eliminate the confusing surrounding the MAX_REQUEST_BLOCKS constant
Addresses https://github.com/status-im/nim-beacon-chain/issues/1366
removed in 0.12.2 - the flow, in particular when the other peer doesn't
support snappy, is hard to follow because of the trial-and-error
approach - removing it simplifies things and removes some of the
hard-to-read parts of the thunking etc
this resolves some peer counting issues that were happening because the
lifetime future in PeerInfo was unreliable (multiple PeerInfo instances
existed per peer)
In addition, this solves another race condition: when connecting to a
peer and later dialling that protocol, it is not certain that the same
connection will be used if there's a concurrent incoming peer connection
ongoing - better not make too many assumptions about who sent statuses
when.
* Allow sync manager process blocks one by one.
* Log storeBlock() and updateHead() duration.
* Calculate duration only for blocks added without any error.
* Fix float compilation error.
* Fix duration.
* Fix SyncQueue tests.
