remove get_epoch_start_slot(...) kludge and update to work exactly as 0.7.1 specifies; remove unused get_attestation_participants_cached(...); update AttestationData to 0.7.1 (being the last data structure, I believe, remaining for such; remove potentially spurious/certainly not-in-spec assertion from compute_committee(...); fix state sim to work with new get_epoch_start_slot/AttestationData/etc setup where it can't stuff all shards' attestations from same slot in the same MIN_ATTESTATION_INCLUSION_DELAY rotating/circular buffer of seq[Attestation]s without more involved shuffling of shard/slot calculation order; fix attestation pool testing to be consistent with get_epoch_start_slot(...)

Remove get_crosslink_committees_at_slot and fix research/state_sim (#291)
* migrate attestation pool tests from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* rm obsolete, unused get_crosslink_committees_at_slot_cached(...) and migrate tests/test_state_transition from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* migrate tests/testutil from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* use more pervasive caching infrastructure, initially of compute_committee; remove buggy (and per-index) shuffling to fix research/state_sim, which was noticing validators on multiple shard committees; rm now-unused specific get_attesting_balance_cached

* add some get_active_validator_index caching

* rm obsolete/unused get_attesting_indices_cached

* rm get_crosslink_committees_at_slot(...)

* some more 0.7 changes -- some of which can't be completed pending some data structure updates -- and shard handling changes to offset with epoch start shards

Dustin Brody d977c96ae1 0.6.1 - signing_root, deposits, validator indices and committee count (#261)
* signed_root -> signing_root

* implement new process_deposit; update timing parameters to 0.6.1; update Deposit to 0.6.1 and remove DepositInput

* update get_active_validator_indices and get_epoch_committee_count to 0.6.1; rm get_current_epoch_committee_count, get_previous_epoch_committee_count, and get_next_epoch_committee_count; bump state_sim default validator count a bit more

* re-introduce 0.5.1-ish get_active_validator_indices, get_epoch_committee_count as scaffolding for still-0.5.1ish shuffling
2019-05-09 14:27:37 +02:00
Dustin Brody c53de3e550 Caching updates/refactoring & state_sim defaults updates (#235)
* rm now-superceded shuffling cache (shuffling is only called from get_crosslinks), which was badly architected due to trying to exist in state; rm one more vestige of previous light-client regime (one more to go, from datatypes)

* fix wrong shuffling list size (active validator size, not validator size) to make consistent with 0.5.1 (will be inconsistent with testnet0); fix typo and change defaults in state_sim

* doAssert a couple of constant relationships necessary to avoid underflow; rm non-spec, unused helper function get_new_recent_block_roots

* refactor separate crosslink_committee_cache and winning_root_participants_cache(s) into StateData object; remove last vestige of previous shuffling cache

* separate out caching parts of StateData to new StateCache object

More 0.5.1 spec updates (#195)
* rm gone-in-0.5.0 Proposal, verifyBlockSignature, and slot check which moved to spec function processBlockHeader

* mark get_attestation_participants and get_epoch_committee_count as 0.5.1; finish updating processAttestations to 0.5.1; add kludgy workaround for bug relating to get_winning_roots_etc using crosslink_data_root as index when we have that as ZERO_HASH for all leading to it confusing attesters on different shards; rm BeaconState.latest_attestations, which splits into previous_epoch_attestations and current_epoch_attestations

* Fix CI due to removed latest_attestations field

Dustin Brody f36c2d86dc begin 0.5.0 spec update (#179)
* begin 0.5.0 spec update: parent_root -> previous_block_root, BeaconState.justified_epoch -> BeaconState.current_justified_epoch, DOMAIN_PROPOSAL -> DOMAIN_BEACON_BLOCK, temporarily rename BeaconBlockHeader to BeaconBlockHeaderRLP to allow for gradual re-merging without disrupting RLP; mark a few unchanged functions and data types, implement get_temporary_block_header/get_empty_block/should_update_validator_registry/processBlockHeader/cacheState; update a few others

* a dozen or so more trivial mostly comment changes, finding more unchanged parts of 0.5.0

* several more trivial changes; goal is to reduce noise around the upcoming substantial changes (epoch processing, etc)
