Adds a `--light-client-data-max-periods` option to override the number
of sync committee periods to retain light client data.
Raising it above the default enables archive nodes to serve full data.
Lowering below the default speeds up import times (still no persistence)
* Add support for launching Geth and Nimbus-eth1 nodes in launch_local_simulation
* Prevent undefined variables errors when Nimbus and Geth are not launched

This updates `nim-ssz-serialization` to
`3db6cc0f282708aca6c290914488edd832971d61`.
Notable changes:
- Use `uint64` for `GeneralizedIndex`
- Add support for building merkle multiproofs
Combines the LC data configuration options (serve / importMode), the
callbacks (finality / optimistic LC update) as well as the cache storing
light client data, into a new `LightClientDataStore` structure.
Also moves the structure into a light client specific file.
* Initial commit
* Make `events` API spec compliant.
* Add `Eth-Consensus-Version` in responses.
* Bump chronos to get redirect with headers working.
* Add `is_optimistic` field and handling to syncing RestSyncInfo.
* adopt LC REST API with v0 suffix (without proofs)
Adopts the light client data REST API used by Lodestar as defined in
https://github.com/ethereum/beacon-APIs/pull/181 with a v0 suffix.
Requests:
- `/eth/v0/beacon/light_client/bootstrap/{block_root}`
- `/eth/v0/beacon/light_client/updates?start_period={start_period}&count={count}`
- `/eth/v0/beacon/light_client/finality_update`
- `/eth/v0/beacon/light_client/optimistic_update`
HTTP Server-Sent Events (SSE):
- `light_client_finality_update_v0`
- `light_client_optimistic_update_v0`
More work is needed to adopt the proofs endpoint, it is not included.
* initialize event queues
* register event topics
`m.depositsChain.blocks.len` may change during `startEth1Syncing`. If
that happened, an additional check now ensures that `scratchMerkleizer`
was initialized before attempting to use it.
If database access errors are encountered while proccessing LC data,
track the section which was accessed without errors so that the rest
may be attempted to be re-indexed later.
* systemd: use same service file as package
* systemd: recommend setting up a user
* clean up obsolete / ephemeral notes
* eth1 -> execution, in many places
* clean up docker instructions to match the experience of running the
runner script
* add basic instructions / links for execution clients other than geth
* clear a few more references to JSON-RPC, update to REST
* update hardware requirements with execution client extras
* start talking about merge requirements (this needs a dedicated page)
* note that binaries do exist, where relevant
* list gitcoin under donations
* update syncing docs
* `NOT` is for `NOTICE` in logs
* update rpi hardware recommendations
* prevent automatic doppelganger restarts in systemd service file
Ensures that all intermediate blocks are reported if a small gap is
encountered when downloading optimistic blocks. Gaps may occur when
a block is missed and still downloading, or when EL processing is slow.
If the gap exceeds 1 epoch, optimistic block stream jumps to latest.
* check for and log gossip broadcast failure
* switch notices to warns; update LC variables regardless
* don't both return a Result and log sending error
* add metrics counter for failed-due-to-no-peers and removed unnecessary async
* don't report failure of sync committee messages
* remove redundant metric
* document metric being incremented
