When fetching historical `getSyncCommitteeDuties` for the very first
sync committee period, the case must be handled where Altair may not
have been scheduled on a sync committee period boundary.
When `scripts/geth_binaries.sh` was updated, as a side effect of dumping
downloaded Geth tarballs / zips into the repo root directory, artifacts
for Jenkins jobs started preserving those downloads with every job,
repeatedly leading to full disks. Exclude those downloads from Jenkins.
When an uncached `ShufflingRef` is requested, we currently replay state
which can take several seconds. Acceleration is possible by:
1. Start from any state with locked-in `get_active_validator_indices`.
Any blocks / slots applied to such a state can only affect that
result for future epochs, so are viable for querying target epoch.
`compute_activation_exit_epoch(state.slot.epoch) > target.epoch`
2. Determine highest common ancestor among `state` and `target.blck`.
At the ancestor slot, same rules re `get_active_validator_indices`.
`compute_activation_exit_epoch(ancestorSlot.epoch) > target.epoch`
3. We now have a `state` that shares history with `target.blck` up
through a common ancestor slot. Any blocks / slots that the `state`
contains, which are not part of the `target.blck` history, affect
`get_active_validator_indices` at epochs _after_ `target.epoch`.
4. Select `state.randao_mixes[N]` that is closest to common ancestor.
Either direction is fine (above / below ancestor).
5. From that RANDAO mix, mix in / out all RANDAO reveals from blocks
in-between. This is just an XOR operation, so fully reversible.
`mix = mix xor SHA256(blck.message.body.randao_reveal)`
6. Compute the attester dependent slot from `target.epoch`.
`if epoch >= 2: (target.epoch - 1).start_slot - 1 else: GENESIS_SLOT`
7. Trace back from `target.blck` to the attester dependent slot.
We now have the destination for which we want to obtain RANDAO.
8. Mix in all RANDAO reveals from blocks up through the `dependentBlck`.
Same method, no special handling necessary for epoch transitions.
9. Combine `get_active_validator_indices` from `state` at `target.epoch`
with the recovered RANDAO value at `dependentBlck` to obtain the
requested shuffling, and construct the `ShufflingRef` without replay.

* fix SSZ response for `produceBlindedBlock`
In `produceBlindedBlock`, we sent the `ForkedBlindedBeaconBlock` when
requested to reply in SSZ format. However, expected result is just the
inner `ForkyBlindedBeaconBlock` together with `eth-consensus-version`.
Note: We do not use SSZ format in our VC for this endpoint at this time,
which explains why we haven't noticed earlier.
* fix Altair/Phase0
* Incremental pruning
When turning on pruning the first time the current pruning algorithm
will prune the full database at startup. This delays restart
unnecessarily, since all of the pruned space is not needed at once.
This PR introduces incremental pruning such that we will never prune
more than 32 blocks or the sync speed, whichever is higher.
This mode is expected to become default in a follow-up release.
* Kzg: Load trusted setup
* scripts/launch_local_testnet.sh: set FIELD_ELEMENTS_PER_BLOB
* Use right setup file for mainnet/minimal
* Force rebuild
* Add comment explaining why build with -f
`attachMerkleProofs` is used by `mockUpdateStateForNewDeposit` to create
a single deposit. The function doesn't work correctly when trying with
with multiple deposits, though. Fix this to enable more complex tests,
and also return the `deposit_root` for forming matching `Eth1Data`.
* final portion of non-trivial v1.3.0 bumps
Updates unchanged logic to latest v1.3.0 consensus-specs refs,
and cleans up surrounding sections / syncs comments, and so on.
```
https://github.com/ethereum/consensus-specs/(blob|tree)/(?!v1\.3\.0/)
```
* lint
* linebreak
* cleanup `state_transition_epoch` and bump to v1.3.0
More v1.3.0 consensus-specs bumps, focused on `state_transition_epoch`.
Also fixed `current_epoch` spurious style check warning, and cleanup.
* Update beacon_chain/spec/state_transition_epoch.nim
Make intent clearer about when to expect `bls_to_execution_changes`,
and replace test-time errors with compile-time errors if the field
is renamed or goes away in the future.
The `SignedContributionAndProof: invalid contribution signature` check
is sometimes hit around fork boundaries when running local testnet.
To avoid failing CI, revert this isntance to a plain `errReject` until
the underlying problem is addressed.
* disable conditionality of warning disabling
* add copyright notice with current year
* express version constraint in nimble file
* also needs copyright year
Instead of comparing against current base branch head, use the common
ancestor of the PR and the base branch to avoid false positives when
a year was bumped in the base branch but not yet merged into the PR.
