From d2f190eabc0ef9bf87fb946bc90f7c699c8bde66 Mon Sep 17 00:00:00 2001 From: Steven Schroeder Date: Mon, 6 May 2019 09:36:51 -0500 Subject: [PATCH 21/68] Upgrade SSZ to v0.5.1 (#611) * Rewrite hash_tree_root convenience functions for SSZ v0.5.1. * Add hash_tree_root function to Artemis SSZ container types. * Check in fixes for all hash_tree_root usages except BeaconState. BeaconState is still pending. * First pass hash_tree_root for BeaconState, resolve majority of compile errors. * Finish BeaconState hash_tree_root, resolve remaining compile errors. * SSZ mix_in_length helper for hash_tree_root calculation must use little endian byte order. * Fixes to make merkleize and pack v0.5.1 compliant. * Remove references to old merkleHash function. * Refactor SSZ hash_tree_root to eliminate duplicated boilerplate code where possible. --- .../data/adapter/TimeSeriesAdapter.java | 11 +- .../datastructures/blocks/BeaconBlock.java | 25 +- .../blocks/BeaconBlockBody.java | 17 ++ .../blocks/BeaconBlockHeader.java | 21 +- .../datastructures/blocks/Eth1Data.java | 10 + .../datastructures/blocks/Eth1DataVote.java | 11 + .../operations/Attestation.java | 17 +- .../operations/AttestationData.java | 16 ++ .../AttestationDataAndCustodyBit.java | 11 + .../operations/AttesterSlashing.java | 13 +- .../datastructures/operations/Deposit.java | 16 +- .../operations/DepositData.java | 12 + .../operations/DepositInput.java | 15 +- .../operations/ProposerSlashing.java | 16 +- .../operations/SlashableAttestation.java | 16 ++ .../datastructures/operations/Transfer.java | 31 ++- .../operations/VoluntaryExit.java | 28 ++- .../datastructures/state/BeaconState.java | 90 ++++++- .../datastructures/state/Crosslink.java | 10 + .../artemis/datastructures/state/Fork.java | 20 +- .../state/PendingAttestation.java | 13 + .../datastructures/state/Validator.java | 15 ++ .../datastructures/util/AttestationUtil.java | 8 +- .../datastructures/util/BeaconBlockUtil.java | 3 +- .../datastructures/util/BeaconStateUtil.java | 23 +- .../datastructures/state/ForkTest.java | 4 +- .../artemis/statetransition/LmdGhost.java | 3 +- .../statetransition/StateProcessor.java | 13 +- .../statetransition/StateTransition.java | 3 +- .../util/BlockProcessorUtil.java | 23 +- .../util/EpochProcessorUtil.java | 14 +- lib/cava-ssz-1.0.0-dev.jar | Bin 50660 -> 50660 bytes .../artemis/util/hashtree/HashTreeUtil.java | 236 ++++++++++++------ .../artemis/util/hashtree/Merkleizable.java | 22 ++ .../coordinator/ValidatorCoordinator.java | 13 +- 35 files changed, 621 insertions(+), 178 deletions(-) create mode 100644 util/src/main/java/tech/pegasys/artemis/util/hashtree/Merkleizable.java diff --git a/data/adapter/src/main/java/tech/pegasys/artemis/data/adapter/TimeSeriesAdapter.java b/data/adapter/src/main/java/tech/pegasys/artemis/data/adapter/TimeSeriesAdapter.java index 75d2425e314..400633bb225 100644 --- a/data/adapter/src/main/java/tech/pegasys/artemis/data/adapter/TimeSeriesAdapter.java +++ b/data/adapter/src/main/java/tech/pegasys/artemis/data/adapter/TimeSeriesAdapter.java @@ -21,7 +21,6 @@ import tech.pegasys.artemis.datastructures.state.BeaconState;
