* 60% state replay speedup
* don't use HashList for epoch participation - in addition to the code
currently clearing the caches several times redundantly, clearing has to
be done each block nullifying the benefit (35%)
* introduce active balance cache - computing it is slow due to cache
unfriendliness in the random access pattern and bounds checking and we
do it for every block - this cache follows the same update pattern as
the active validator index cache (20%)
* avoid recomputing base reward several times per attestation (5%)
Applying 1024 blocks goes from 20s to ~8s on my laptop - these kinds of
requests happen on historical REST queries but also whenever there's a
reorg.
* fix test and diffs
* consolidate consensus spec transition test fixtures
* include capella
* consoliate fork test fixtures
* note change in EIP-4844 process_block in alpha.2
Other changes:
* More optimal search for TTD block.
* Add timeouts to all REST requests during trusted node sync.
Fixes#4037
* Removed support for storing a deposit snapshot in the network
metadata.
* Types and scaffolding for EIP-4844
This commit adds the EIP-4844 spec types, and fills in
scaffolding/boilerplate for the use of these types across the repo.
None of the actual EIP-4844 logic is introduced yet.
This follows the pattern used by @tersec when introducing Capella (#4276).
* use eth2-networks fork
* review feedback: add static check EIP4844_FORK_EPOCH == FAR_FUTURE_EPOCH
* review feedback: remove EIP4844 from /eth/v1/config/spec response
* Cleanup / review feedback
* Fix REST test
* implement several capellaImplementationMissing points
* don't register validator activity for not-active validators
* don't check validator indices already coming out of committees which exist; must be active validators, or else other deeper bugs
We currently use `BlockError` for both beacon blocks and LC objects.
In light of EIP4844, we will likely also use it for blob sidecars.
To avoid confusion, renaming it to a more generic `VerifierError`,
and update its documentation to be more generic.
To avoid long lines as a followup, also renaming the `block_processor`'s
`BlockProcessingCompleted.completed`->`ProcessingStatus.completed` and
`BlockProcessingCompleted.notCompleted`->`ProcessingStatus.notCompleted`
This PR removes a bunch of code to make TNS aware of era files, avoiding
a duplicated backfill when era files are available.
* reuse chaindag for loading backfill state, replacing the TNS homebrew
* fix era block iteration to skip empty slots
* add tests for `can_advance_slots`
