- 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).
* 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.
- 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
* sync fixes
* fix Status message finalized info
* work around sync starting before initial status exchange
* don't fail block on deposit signature check failure (fixes#989)
* 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
* remove incorrect/obsolete comment; deprecate BeaconState state transition functions
* remove deprecated state_transition(state: var BeaconState)
* add specific workarounds for state_transition() and process_slots() to nfuzz_block() and addTestBlock()
* Jenkins: add timeouts to testnet finalisation tests
- add nicer child process management to "launch_local_testnet.sh"
- correct a comment in "start.sh"
* the Jenkins worker's version of "timeout" doesn't support "-v"
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions
* convert tests/test_state_transition.nim to use HashedBeaconState
* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)
* ssz: move ref support outside
Instead of allocating ref's inside SSZ, move it to separate helper:
* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected
TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..

In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.
This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time
In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.
* Add "drop by score" ability to PeerPool.
Add tests.
Fix syncmanager queue to start from most fresh data.
* Fix endless cycle at the end of syncing process.
* fix mainnet finalization and swith eth2_network_simulation to a kind of small-mainnet profile
* Fix slot reference in trace logging
* bump a couple of spec refs from v0.11.0 to v0.11.1
* bump another spec ref to v0.11.1, one more try at Jenkins test vector download CI issue
* fix other slot reference in trace logging and skip past single-block/multi-slot gaps to re-approach from ancestry side by state_transitioning, by requiring exact match on both root hash and slot for fast path
* make more precise the fast path condition
* redo logic to make uniform with BeaconChainDB; fix chronos deprecation warning
* revert not-working replacement of deprecated chronos futures `or`
* switch testnet1 to mainnet
