* switch state transition caching usage to shuffled active validator indices to match EpochRef
* refactor the EpochRef -> StateCache transformation; elide pointless mapIt
* limit state passed between get_beacon_committee(...) and compute_committee(...)
* tweaks
The first offset of an SSZ object should always have a fixed constant
value. Otherwise, some unused bytes may appear between the fixed portion
and the dynamic portion.
Please note that this fix shutds down the minimal forward compatibility
currently supported by the SSZ format (and thus, the expected behavior
must be clarified in the SSZ spec).
* plumbing between block pool and state transition functions around active validator indices and committees
* have shared epochrefs followed by blockref tree while allowing for skipped slots
* factor out the epoch info extraction; document how the EpochRef follows forks
* be stricter about SSZ length prefix
* compute zeroHash list at compile time
* remove SSZ schema stuff
* move SSZ navigation to ncli
* cleanup a few leftover openArray uses
* Add ability to reset state of sync manager.
Fix bug when sync got stuck on `zero-point` reset.
Fix bug when sync got stuck when some of the workers waiting for failing one.
* Remove debugging comments and imports.
* Remove not used pendingLock.
The lack of body of `goodbye` in sync_protocol.nim was preventing
the respective LibP2P protocol to be mounted and advertised on the
network.
Adding a body fixes that, but I've also made some changes in the
P2P protocol codegen that will prevent the issue from happening
again (no body is now considered the equivalent of having an empty
body).
the cast worked around the bug at compile time by means of casting, but
introduced a runtime error, because the pre-cast type was still being
used during deserialization
- we have a new binary which connects via RPC to the respective BN and has an internal clock - waking it up on every slot
- the BN has a new option called --external-validators and currently in order to have the VC binaries to run we need to pass EXTERNAL_VALIDATORS=yes to make
- factored some code out of beacon_node.nim for easier reuse in validator_api.nim and validator_client.nim
- the VC loads its associated private keys from the datadir for its BN
- most of the validator API calls have been implemented as a stub.
- the VC polls its BN at the start of each epoch - getting a list of all active validators for the current epoch - and then continues to request blocks and sign them with its appropriate validators when necessary
* in makeBeaconBlock - use rollback instead
* in tests - this helps state_sim give more accurate data and makes it
30% faster
* fix some usages of raw BeaconState
* update more spec refs in beacon_chain/spec/presets; skip skipped constant sanity checks also from markdown reports' perspectives
* mark skipped as skipped in markdown
* Fix nbench compilation with HashedBeaconState
* Add nbench to tooling
* use newClone - fix 265e01e404 (r425198575)
* Detail advance_slot and hashTreeRoot
* Report throughput
* Fallback for ARM
* windows does not support inline ASM
The work on this was started last week while I was waiting
for a decision on the "Async Snappy" PR. It was prompted by
a failing test in the test suite, where the HashingStream
was inserting some incorrectly padded chunks that affected
the result of `hash_tree_root`. Instead of working around
the problem in the HashingStream, I've decided to implement
a planned optimisation that allows us to remove the hashing
stream altogether.
With the optimisation in place, `hash_tree_root` will now
use only stack memory and only the precise amount neccesary
to build the chunks-merging tree.
* switch state cache to use ref statedata objects to limit memory usage
* more directly initialize ref StateData
* use HashedBeaconState instead of StateData to try to fix memory leak
* switch cache to seq[ref HashedBeaconState]
* remove unused import

* print ForkDigest and Version nicely
* dump incoming blocks
* fix crash when libp2p peer connection is closed
* update chunk size to 16 to work around missing blocks when syncing
* bump libp2p
* bump libp2p
* better deposit skip message
* fix some warnings related to beacon_node splitting; reimplement finalization verification more robustly; improve attestation pool block selection logic
* re-add missing import
* whitelist allowed state transition flags and make rollback/restore naming more consistent
* restore usage of update flags passed into skipAndUpdateState(...) in addition to the potential verifyFinalization flag
* switch rest of rollback -> restore
When replaying state transitions, for the slots that have a block, the
state root is taken from the block. For slots that lack a block, it's
currently calculated using hash_tree_root which is expensive.
Caching the empty slot state roots helps us avoid recalculating this
hash, meaning that for replay, hashes are never calculated. This turns
blocks into fairly lightweight "state-diffs"!
* avoid re-saving state when replaying blocks
* advance empty slots slot-by-slot and save root
* fix sim randomness
* fix sim genesis filename
* introduce `isEpoch` to check if a slot is an epoch slot
