When the BN-embedded LC makes sync progress, pass the corresponding
execution block hash to the EL via `engine_forkchoiceUpdatedV1`.
This allows the EL to sync to wall slot while the chain DAG is behind.
Renamed `--light-client` to `--sync-light-client` for clarity, and
`--light-client-trusted-block-root` to `--trusted-block-root` for
consistency with `nimbus_light_client`.
Note that this does not work well in practice at this time:
- Geth sticks to the optimistic sync:
"Ignoring payload while snap syncing" (when passing the LC head)
"Forkchoice requested unknown head" (when updating to LC head)
- Nethermind syncs to LC head but does not report ancestors as VALID,
so the main forward sync is still stuck in optimistic mode:
"Pre-pivot block, ignored and returned Syncing"
To aid EL client teams in fixing those issues, having this available
as a hidden option is still useful.
* Use final `v1` version for light client protocols
* Unhide LC data collection options
* Default enable LC data serving
* rm unneeded import
* Connect to EL on startup
* Add docs for LC based EL sync
A fix for a bug triggered by recent `Jenkinsfile` refactoring done in:
https://github.com/status-im/nimbus-eth2/pull/3827
Which due to a big in Jenkins Throttling plugin caused jobs to start
running in parallel on the same host despite global configuration that
is supposed to block this:
https://issues.jenkins.io/browse/JENKINS-49173https://github.com/jenkinsci/throttle-concurrent-builds-plugin/pull/68
An attempt to fix this was made in this PR:
https://github.com/status-im/nimbus-eth2/pull/3913
But it was ineffective due to bugs in the Throttle plugin.
As a result semi-random testnet launches would fail with errors like this:
```
./scripts/launch_local_testnet.sh: line 1026: 58977 Killed: 9 ${BEACON_NODE_COMMAND} ...
```
The culprit was the old process cleanup in `scripts/launch_local_testnet.sh`:
```
+ make local-testnet-mainnet
Found old process listening on port 7001, with PID 58977. Killing it.
Found old process listening on port 7002, with PID 59024. Killing it.
Found old process listening on port 7003, withu PID 59027. Killing it.
Found old process listening on port 7004, with PID 59030. Killing it.
```
Which was triggered due to use of immediate assignment for `EXECUTOR_NUMBER`:
```
EXECUTOR_NUMBER := 0
```
Which cause the `EXECUTOR_NUMBER` value set by Jenkins to be ignored.

The ports for the concurrently executing REST and Minimal testnet clash,
leading to some CI failures since #3827 introduced further concurrency.
Adjusting the ports to be distinct across various tests should fix this.
`mkdocs` works with markdown similar to `mdbook` but is generally more
pleasing to the eye and has several nice UX features.
This PR does the bulk of the transition - likely, a followup would be
needed to fully make use of the extra features and navigation.
Book pages have been kept url-compatible, meaning that for the most
part, old links should continue to work!

Changes:
- Name local testnet output folders same as the `make` taget.
- Move both `Jenkinsfile`s to `ci` folder to avoid cluttering repo root.
- Separate builds by platform so logs from macos and linux hosts don't get mixed.
- Detect platform and architecture from Jenkins Job path to use one Jenkinsfile.
- Divide shell commands into as many stages as possible to make debugging easier.
- Generalize running testnets via a `launchLocalTestnet()` Groovy method.
- Handle uploading of results of running testnets stage-by-stage basis.
- Use `catchError()` to upload test results while marking job as failed.
- Abort previously started PR build jobs usin `disableConcurrentBuilds()`.
- Throttle jobs using the new `throttleJobProperty()` function.

* update docs
* introduce mdbook-admonish for nice looking callouts
* new section on data directory
* recommend source build for advanced users and direct the rest to
binaries
* more strongly highlight that execution client is needed
* write an actual deposit guide
* remove cruft / fix links / etc
* Re-enabled requireAllFields after a fix in nim-json-serialization
The problem was that `Option[T]` fields were not treated as optional
when requireAllFields is set to true. This is now fixed in NJS.
* Add makefile targets for recreating the Jenkins simulation runs
* Fix a discrepancy with the REST spec
Adds the `--web3-url` launch argument to `nimbus_light_client` to enable
driving the EL with the optimistic head obtained from LC sync protocol.
This will keep issuing `newPayload` / `forkChoiceUpdated` requests for
new blocks, marking them as optimistic. `ZERO_HASH` is reported as the
finalized block for now.
For consistency with other options, use a common prefix for light client
data configuration options.
* `--serve-light-client-data` --> `--light-client-data-serve`
* `--import-light-client-data` --> `--light-client-data-import-mode`
No deprecation of the old identifiers as they were only sparingly used
and all usage can be easily updated without interferance.
When launched with `--light-client-enable` the latest blocks are fetched
and optimistic candidate blocks are passed to a callback (log for now).
This helps accelerate syncing in the future (optimistic sync).
Introduces a new library for syncing using libp2p based light client
sync protocol, and adds a new `nimbus_light_client` executable that uses
this library for syncing. The new executable emits log messages when
new beacon block headers are received, and is integrated into testing.
Other fixes:
* Fix bit rot in the `make prater-dev-deposit` target.
* Correct content-type in the responses of the Nimbus signing node
* Invalid JSON payload was being sent in the web3signer requests
* `gnosis-chain` -> `gnosis`
Use same name as LH/Teku throughout
* fixes#3504
* fixes large stack temporary that can cause crashes during genesis
detection
The `pyrmont` testnet has been discontinued.
For experiments, it's still possible to run pyrmont nodes by passing a
genesis/config, but this PR removes the bundled `--network:pyrmont`
option.
* update docs
* remove empty docs
* remove obsolete `eth2-stats` page
* Support for Gnosis Chain
`make gnosis-chain-build` will build the Nimbus gnosis chain binary,
stored in `build/nimbus_beacon_node_for_gnosis_chain`.
`make gnosis-chain` will connect to the network.
Other changes:
* Restore compilation with -d:has_genesis_detection
* Removed Makefile target related to testnet0 and testnet1
* Added more debug logging for failed peer handshakes
* Report misconfigured builds which try to embed network metadata
that is incompatible with the currently selected const preset.
* Don't bundle network metadata in minimal builds, as they are not compatible
* Jenkins: get rid of macOS warnings
We're linking object files with debug info with ones without it. Perfectly justified, from our point of view, but dsymutil complains verbosely about it, with no switch to silence it.
It's sometimes useful to simulate what happens when a chain runs from a
given state with a given set of private keys - `wss_sim` allows running
such a simulation.
One use of such a tool is to simulate a weak subjectivity attack,
creating alternative histories of the same chain:
https://notes.status.im/nimbus-insecura-network#
The new format is based on compressed CSV files in two channels:
* Detailed per-epoch data
* Aggregated "daily" summaries
The use of append-only CSV file speeds up significantly the epoch
processing speed during data generation. The use of compression
results in smaller storage requirements overall. The use of the
aggregated files has a very minor cost in both CPU and storage,
but leads to near interactive speed for report generation.
Other changes:
- Implemented support for graceful shut downs to avoid corrupting
the saved files.
- Fixed a memory leak caused by lacking `StateCache` clean up on each
iteration.
- Addressed review comments
- Moved the rewards and penalties calculation code in a separate module
Required invasive changes to existing modules:
- The `data` field of the `KeyedBlockRef` type is made public to be used
by the validator rewards monitor's Chain DAG update procedure.
- The `getForkedBlock` procedure from the `blockchain_dag.nim` module
is made public to be used by the validator rewards monitor's Chain DAG
update procedure.
Used during initial development of the spec, `nbench` has fallen behind
and by and large been superceded by `block_sim`, `state_sim` and
`ncli_db bench`.
* "official" -> "scenarios", like the submodule
* fewer test binaries - various compile hacks have been improved over
time, test suite should follow
* remove obsolete bls tests - there are better test vectors in
nim-blscurve
* remove obsolete mentions of `ssz_testing`
* remove obsolete comments about proc vs globals, unittest2 already uses
proc's
