* 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.
Validators exiting is normal, no need to scream about it
* avoid reallocating seq on big exit queue
* avoid fetching state cache when updating head (it's rarely needed)
* remove incorrectly implemented live validator counts (avoids memory
allocs)
* Add exponential rewind on MissingParent.
* Try to avoid peers which are useless for syncing.
Fix forward sync restart at proper point.
Fix getLocalWallSlot() to not return slots from the future.
* Fix incorrect logs.
* Fix logging.
Enable peer's status messages log on DEBUG level.
* Fix watch task to monitor operation progress, but not local head progress.
* Add more logging information.
Remove recurring failures detection mechanism.
* Concentrate all sensitive writeFile/createPath calls in one place.
Fix eth2_network_simulation for Windows.
* Remove artifacts.
* fix import

* Fix continuous sync queue rewinds on slow PCs.
Fix recurring disconnects on low peer score.
* Calculate average syncing speed, not the current one.
Move speed calculation to different task.
* Address review comments.
* Bump nim-eth to get UseDiscv51 flag
* Switch medalla to discovery v5.1, other targets to v5.0
* Bump nim-eth for better discv5.1 logging
* Bump eth2-testnets for updated medalla bootnodes
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
