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
* 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
