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.
* 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
* 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.

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
* send attestations and exit messages on fork-appropriate topic
* document why use wall clock over attestation slot
* centralize some fork-topic-picking-logic in eth2_network
* pick up new test in summary
* allow specified GetTimeFn for testing purposes
* add GenesisTime and use it in eth2_network
* replace GetTimeFn and GenesisTime with GetBeaconTimeFn
The spec imports are a mess to work with, so this branch cleans them up
a bit to ensure that we avoid generic sandwitches and that importing
stuff generally becomes easier.
* reexport crypto/digest/presets because these are part of the public
symbol set of the rest of the spec types
* don't export `merge` types from `base` - this causes circular deps
* fix circular deps in `ssz/spec_types` - this is the first step in
disentangling ssz from spec
* be explicit about phase0 vs altair - longer term, `altair` will become
the "natural" type set, then merge and so on, so no point in giving
`phase0` special preferential treatment
* Initial commit.
* Exporting getConfig().
* Add beacon node checking procedures.
* Post rebase fixes.
* Use runSlotLoop() from nimbus_beacon_node.
Fallback implementation.
Fixes for ETH2 REST serialization.
* Add beacon_clock.durationToNextSlot().
Move type declarations from beacon_rest_api to json_rest_serialization.
Fix seq[ValidatorIndex] serialization.
Refactor ValidatorPool and add some utility procedures.
Create separate version of validator_client.
* Post-rebase fixes.
Remove CookedPubKey from validator_pool.nim.
* Now we should be able to produce attestations and aggregate and proofs.
But its not working yet.
* Debugging attestation sending.
* Add durationToNextAttestation.
Optimize some debug logs.
Fix aggregation_bits encoding.
Bump chronos/presto.
* Its alive.
* Fixes for launch_local_testnet script.
Bump chronos.
* Switch client API to not use `/api` prefix.
* Post-rebase adjustments.
* Fix endpoint for publishBlock().
* Add CONFIG_NAME.
Add more checks to ensure that beacon_node is compatible.
* Add beacon committee subscription support to validator_client.
* Fix stacktrace should be an array of strings.
Fix committee subscriptions should not be `data` keyed.
* Log duration to next block proposal.
* Fix beacon_node_status import.
* Use jsonMsgResponse() instead of jsonError().
* Fix graffityBytes usage.
Remove unnecessary `await`.
Adjust creation of SignedBlock instance.
Remove legacy files.
* Rework durationToNextSlot() and durationToNextEpoch() to use `fromNow`.
* Fix race condition for block proposal and attestations for same slot.
Fix local_testnet script to properly kill tasks on Windows.
Bump chronos and nim-http-tools, to allow connections to infura.io (basic auth).
* Catch services errors.
Improve performance of local_testnet.sh script on Windows.
Fix race condition when attestation producing.
* Post-rebase fixes.
* Bump chronos and presto.
* Calculate block publishing delay.
Fix pkill in one more place.
* Add error handling and timeouts to firstSuccess() template.
Add onceToAll() template.
Add checkNodes() procedure.
Refactor firstSuccess() template.
Add error checking to api.nim calls.
* Deprecated usage onceToAll() for better stability.
Address comment and send attestations asap.
* Avoid unnecessary loop when calculating minimal duration.
* Implement the new Altair req/resp protocols
Also fixes the altair message-id computation by providing the correct
forkdigest prefix in `isAltairTopic`.
