* Handle some web3 timeouts better
* Add support for developer .env files
* Eth1 improvements; Mainnet genesis state
Notable changes:
* The deposits table have been removed from the database. The client
will no longer process all deposits on start-up.
* The network metadata now includes a "state snapshot" of the deposit
contract. This allows the client to skip syncing deposits made prior
to the snapshot (i.e. genesis). Suitable metadata added for Pyrmont
and Mainnet.
* The Eth1 monitor won't be started unless there are validators attached
to the node.
* The genesis detection code is now optional and disabled by default
* Bugfix: The client should not produce blocks that will fail validation
when it hasn't downloaded the latest deposits yet
* Bugfix: Work around the database corruption affecting Pyrmont nodes
* Remove metadata for Toledo and Medalla
* log when database is loading (to avoid confusion)
* generate network keys later during startup
* fix quarantine not scheduling chain of parents for download and
increase size to one epoch
* log validator count, enr and peerid more clearly on startup
* Avoid hangs when wss:// is specified for a non-secure HTTP server
* Produce an ERROR when the web3 provider is unsupported, but still launch the node
This introcudes a cache for block summaries, useful for instantiating
the block dag on startup, bringing medalla startup times down from
minutes to seconds.
This is something of a temporary band-aid that would be obsoleted by a
finalized block store.
This reverts commit 63173ab2c1.
It appears the cluster is having trouble staying connected - since the culprit is unknown, this is a first step on the way to what was stable.
Notably, this does not fully revert libp2p itself, merely the gossip version.

Calculating rewards/penalties is slow due to how we compute sets of
attestations validators then use the sets for inclusion checks, to see
who attested. The dominant function during validated block processing /
epoch processing is hash set building and lookup.
This PR inverts the flow by removing the sets and creating a single
large validator status list, then applying all relevant state
attestations, then updating rewards and penalties.
This provides a 10x speedup to epoch processing which in turn speeds up
both empty slot and block processing - for example, on startup, we
replay all non-finalized blocks to prime fork choice - the same when
validating attestations or replaying states on reorg.
* misc memory and perf fixes
* use EpochRef for attestation aggregation
* compress effective balances in memory (medalla unfinalized: 4gb ->
1gb)
* avoid hitting db when rewinding to head or clearance state
* avoid hitting db when blocks can be applied to in-memory state -
speeds up startup considerably
* avoid storing epochref in fork choice
* simplify and speed up beacon block creation flow - avoids state reload
thanks to head rewind optimization
* iterator-based committee and attestation participation help avoid lots
of small memory allocations throughout epoch transition (40% speedup on
epoch processing, for example during startup)
* add constant for threshold
* update ve1.0.0-rc.0 preset spec references
* remove runtime preset ETH1_FOLLOW_DISTANCE from preset files; remove two CI build items to try to keep Travis from timing out
* update attestation extended validation to v1.0.0-rc.0
* attestation block and target must be within same epoch
* remove duplicate attestation epoch/target epoch check
* in spec now
This addresses the issues by detecting and rejecting keystores with
incorrect PBKDF2 and SCrypt params. It also bumps the version of
nim-json-serialization to include a bugfix for incorrect parsing
of json files featuring comments.
It turns out that we often save lots of states in the database that are
the result of empty slot processing only - here, we make sure to only
save a state if a block follows - this fixes several issues:
* empty slot states are not always pruned leading to state database size
explosion
* storing states is (very) slow which slows down processing in general,
so we should only do it when it's likely to be useful
* attestation processing doesn't get stuck on saving random states that
won't appear in the chain history
* in exit pool, filter out already-packaged messages; bundle remaining messages into beaconblocks
* filter messages at block construction time
* allow adding up to intended capacity of buffers, beyond per-block limits
* document rationale/design for filtering mechanism
* fixed#1663 - Interger overflow in compute_start_slot_at_epoch through RPC
* changed the way the overflow check is done - took the approach from PR #1797 - see the comment in PR #1810 for more details
this would reallocate the attestation queue on every attestation and
other call to update_time, causing quite the overhead (~10% cpu spent
when gossiping)

about 40% better slot processing times (with LTO enabled) - these don't
do BLS but are used
heavily during replay (state transition = slot + block transition)

* Add test for a bug.
* Fix eth2_network disconnect should deletePeer not release.
More PeerPool refactoring.
* remove some superfluous gcsafes

* add ncli_db subcommand to prune database of unnecessary blocks, states, and state roots
* tweak comments
* reduce default aggressiveness in pruning old states
* move copyPrunedDatabase() to ncli_db, as it's not generally useful as part of beacon_chain_db and doesn't use any internal interfaces
* Syncing workers now not bound to peers.
Sync status is now printed in statusbar.
* Add `SyncQueue.outSlot` to statusbar too.
* Add `inRangeEvent` and `rangeAge` parameter.
* Fix rangeAge is not depends on SyncQueue latest slot.
Fix syncManager to start from latest local head slot.
* Add notInRange event.
* Remove suspects field.
Validator duties proceed slot-by-slot - we should not start a new
validator duty iteration before the previous one is gone or we might run
into consistency and voting issues
* Quick fix to prune some states, pending smarter state storage
Adverse effects might include slow rewinds - typically the protocol
doesn't ask for pre-finalized states but RPC might
* document issue, add test
* fix cache miss log
per spec, we must half-close request stream - not doing so may lead to
failure of the other end to start processing our request leading to
timeouts.
In particular, this fixes many sync problems that have been seen on
medalla.
* remove safeClose - close no longer raises
* use per-chunk timeouts in request processing
* stop discarding non-existent future epochs during epoch state transitions; remove a pointless StateCache() construction in advance_slots()
* update nbench to pass StateCache to process_slots()
