* re-add minimal preset constant checking; organize presets to better support multiple spec versions
* bump spec ref
* increase Azure timeout to 90 minutes to accomodate Nim compiler building
- better logging & retrying requests on the VC side if the BN fails for some reason
- VC now fetches the attestation duties 1 epoch in advance - in the future it will tell the BN to subscribe to the appropriate attestation topics in advance based on that info
- a bunch of other code cleanup & fixes such as better naming for consoles when using multitail, etc.
reviewed in PR #1184 - proper review of the API & VC are pending
* collect signature production and verificaiton in one place
Signatures are made over data and domain - here we collect all such
activities in one place.
Also:
* security: fix cast-before-range-check
* log block/attestation verification consistently
* run block verification based on `getProposer` in its own history
* clean up some unused stuff
* import
* missing raises
* random fixes
* create dump dir on startup
* don't crash on failure to write dump
* fix a few `uint64` instances being used when indexing arrays - this
should be a compile error but isn't due to compiler bugs
* fix standalone test_block_pool compilation
* add signed block processing in ncli
* reuse cache entry instead of allocating a new one
* allow for small clock disparities when validating blocks
- moved "process_dashboard.nim" in "tools/"
- README: made Witti the documented testnet and added instructions for
getting metrics out of the local node
- moved Prometheus config file generation in its own script
- the static Grafana dashboard definition now covers all nodes, using
a variable; only the remote testnet dashboards need to be dynamically
generated
- "launch_local_testnet.sh" no longer needs a "--grafana" option
- each BN gets half of its previous validators as inProcess and the other half goes to the respective VC for that BN - using separate data dirs where the keys are copied
- also removed a few command line options which are no longer necessary
- block proposals originating from a VC are propagated from one BN to the rest properly
- other cleanup & moving code back to since it is no longer used elsewhere
* reorder ssz
* split into hash_trees and ssz_serialization, roughly, for hashing and
IO
* move bitseqs into ssz (from stew)
* clean up imports
* docs, imports
Add SeenTable to avoid continuous attempts to dead peers.
Refactor onSecond.
Block backward sync while forward sync is working.
SyncManager now checks responses according corresponding requests + tests.
SyncManager now watching for not progressing local_head_slot and resets SyncQueue.
* wip: cache
* cache lists and arrays of complex objects (5x block processing speed
on ncli_db)
trivial baseline cache that stores tree in flat memory structure
* support array of uint64
* work around type issues
* more type compiler bug workarounds
* cache balances, more type fixes
* index type
* ncli_db: add validation flag, better ux
* int64 fixes
* test fix
* "oops"

* support all basic types
* cleanups
* a few more cleanups
* 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).
