Re-export `context_deserialize_derive` inside of `context_deserialize` so they are both available from the same interface, which matches how popular crates (like `serde`) handle this.
This also nests both crates inside a new `context_deserialize` directory which will make it easier to eventually spin out into a different repo (if/when) we decide to do that (plus I prefer it aesthetically).
#7815
- removes all existing spans, so some span fields that appear in logs like `service_name` may be lost.
- instruments a few key code paths in the beacon node, starting from **root spans** named below:
* Gossip block and blobs
* `process_gossip_data_column_sidecar`
* `process_gossip_blob`
* `process_gossip_block`
* Rpc block and blobs
* `process_rpc_block`
* `process_rpc_blobs`
* `process_rpc_custody_columns`
* Rpc blocks (range and backfill)
* `process_chain_segment`
* `PendingComponents` lifecycle
* `pending_components`
To test locally:
* Run Grafana and Tempo with https://github.com/sigp/lighthouse-metrics/pull/57
* Run Lighthouse BN with `--telemetry-collector-url http://localhost:4317`
Some captured traces can be found here: https://hackmd.io/@jimmygchen/r1sLOxPPeg
Removing the old spans seem to have reduced the memory usage quite a lot - i think we were using them on long running tasks and too excessively:

Although we're working on jemalloc profiler support in https://github.com/sigp/lighthouse/pull/7746, heaptrack seems to be producing more sensible results.
This PR adds a heaptrack profile and a heaptrack feature so that we no longer need to patch the code in order to use heaptrack. This may prove complementary to jemalloc profiling, so I think there is no harm in having both.
Update `c-kzg` from `v1` to `v2`. My motivation here is that `alloy-consensus` now uses `c-kzg` in `v2` and this results in a conflict when using lighthouse in combination with latest alloy. I tried also to disable the `czkg` feature in alloy, but the conflict persisted.
See here for the alloy update to `c-kzg v2`: https://github.com/alloy-rs/alloy/pull/2240
Error:
```
error: failed to select a version for `c-kzg`.
...
versions that meet the requirements `^1` are: 1.0.3, 1.0.2, 1.0.0
the package `c-kzg` links to the native library `ckzg`, but it conflicts with a previous package which links to `ckzg` as well:
package `c-kzg v2.1.0`
... which satisfies dependency `c-kzg = "^2.1"` of package `alloy-consensus v0.13.0`
... which satisfies dependency `alloy-consensus = "^0.13.0"` of package ...
...
```
- Upgrade `alloy-consensus` to `0.14.0` and disable all default features
- Upgrade `c-kzg` to `v2.1.0`
- Upgrade `alloy-primitives` to `1.0.0`
- Adapt the code to the new API `c-kzg`
- There is now `NO_PRECOMPUTE` as my understand from https://github.com/ethereum/c-kzg-4844/pull/545/files we should use `0` here as `new_from_trusted_setup_no_precomp` does not precomp. But maybe it is misleading. For all other places I used `RECOMMENDED_PRECOMP_WIDTH` because `8` is matching the recommendation.
- `BYTES_PER_G1_POINT` and `BYTES_PER_G2_POINT` are no longer public in `c-kzg`
- I adapted two tests that checking for the `Attestation` bitfield size. But I could not pinpoint to what has changed and why now 8 bytes less. I would be happy about any hint, and if this is correct. I found related a PR here: https://github.com/sigp/lighthouse/pull/6915
- Use same fields names, in json, as well as `c-kzg` and `rust_eth_kzg` for `g1_monomial`, `g1_lagrange`, and `g2_monomial`

After the electra fork which includes EIP 6110, the beacon node no longer needs the eth1 bridging mechanism to include new deposits as they are provided by the EL as a `deposit_request`. So after electra + a transition period where the finalized bridge deposits pre-fork are included through the old mechanism, we no longer need the elaborate machinery we had to get deposit contract data from the execution layer.
Since holesky has already forked to electra and completed the transition period, this PR basically checks to see if removing all the eth1 related logic leads to any surprises.
Add `console-subscriber` feature for debugging tokio async tasks.
Supersedes #7420 to work with `unstable`.
Usage:
- Build Lighthouse with `RUSTFLAGS=--cfg tokio_unstable` and `--features console-subscriber`, e.g.:
```
RUSTFLAGS=-"-cfg=tokio_unstable --remap-path-prefix=$(pwd)=." FEATURES=console-subscriber make
```
- Run the Lighthouse binary.
- Install `tokio-console` and run it in a terminal.
Update `engine_getBlobsV2` response type to `Option<Vec<BlobsAndProofV2>>`. See recent spec change [here](https://github.com/ethereum/execution-apis/pull/630).
Added some tests to cover basic fetch blob scenarios.
Which issue # does this PR address?
This PR addresses reproducible builds. The current dockerfile builds the lighthouse binary but not reproducibly.
You can verify that by following these steps:
```
docker build --no-cache --output=. .
mv usr/local/bin/lighthouse lighthouse1
rm usr/local/bin/lighthouse
docker build --no-cache --output=. .
mv usr/local/bin/lighthouse lighthouse2
sha256sum lighthouse1 lighthouse2
```
You will notice that each one of the binaries has a different checksum upon each build. This is critical for systems that depends on requiring reproducible builds, such as running lighthouse in confidential computing, like Intel TDX.
This PR adds a new build profile as well as a Dockerfile.reproducible that enables building the lighthouse binary reproducibly.
By following the steps I listed above, you will be able to verify that the resulted binary has the same hash upon several subsequent builds for the same version.
How to test it:
```
mkdir output1 output2
docker build --no-cache -f Dockerfile.reproducible --output=output1 .
docker build --no-cache -f Dockerfile.reproducible --output=output2 .
sha256sum output1/lighthouse output2/lighthouse
# hashes should be identical
rm -rf output1 output2
```
- Create trait `ValidatorStore` with all functions used by the `validator_services`
- Make `validator_services` generic on `S: ValidatorStore`
- Introduce `LighthouseValidatorStore`, which has identical functionality to the old `ValidatorStore`
- Remove dependencies (especially `environment`) from `validator_services` and `beacon_node_fallback` in order to be able to cleanly use them in Anchor
When we perform data column gossip verification, we sometimes see multiple proposer shuffling cache miss simultaneously and this results in multiple threads computing the shuffling cache and potentially slows down the gossip verification.
Proposal here is to use a `OnceCell` for each shuffling key to make sure it's only computed once. I have only implemented this in data column verification as a PoC, but this can also be applied to blob and block verification

#7153#7146#7147#7148 -> Thanks to @ackintosh
This PR does the following:
1. Disable logging to file when using either `--logfile-max-number 0` or `--logfile-max-size 0`. Note that disabling the log file in this way will also disable `discv5` and `libp2p` logging.
1. `discv5` and `libp2p` logging will be disabled by default unless running `beacon_node` or `boot_node`. This also should fix the VC panic we were seeing.
1. Removes log rotation and compression from `libp2p` and `discv5` logs. It is now limited to 1 file and will rotate based on the value of the `--logfile-max-size` flag. We could potentially add flags specifically to control the size/number of these, however I felt a single log file was sufficient. Perhaps @AgeManning has opinions about this?
1. Removes all dependency logging and references to `dep_log`.
1. Introduces workspace filtering to file and stdout. This explicitly allows logs from members of the Lighthouse workspace, disallowing all others. It uses a proc macro which pulls the member list from cargo metadata at compile time. This might be over-engineered but my hope is that this list will not require maintenance.
1. Unifies file and stdout JSON format. With slog, the formats were slightly different. @threehrsleep worked to maintain that format difference, to ensure there was no breaking changes. If these format differences are actually problematic we can restore it, however I felt the added complexity wasn't worth it.
1. General code improvements and cleanup.
I feel it's preferable to do this explicitly by updating the revision on `Cargo.toml` rather than implicitly by letting `Cargo.lock` control the revision of the branch.
Resolves#7091
The `prometheus` crate pulls in `protobuf 2.x` which fails cargo audit. We actually dont use any `protobuf` related features in LH. By disabling default features for `prometheus`, we no longer pull in the `protobuf` crate
We forked `gossipsub` into the lighthouse repo sometime ago so that we could iterate quicker on implementing back pressure and IDONTWANT.
Meanwhile we have pushed all our changes upstream and we are now the main maintainers of `rust-libp2p` this allows us to use upstream `gossipsub` again.
Nonetheless we still use our forked repo to give us freedom to experiment with features before submitting them upstream

Bumps the `ethereum_ssz` version, along with other crates that share the dep.
Primarily, this give us bitfields which can store 128 bytes on the stack before allocating, rather than 32 bytes (https://github.com/sigp/ethereum_ssz/pull/38). The validator count has increase massively since we set it at 32 bytes, so aggregation bitfields (et al) now require a heap allocation. This new value of 128 should get us to ~2m active validators.
* Remove ZeroizeString in favour of Zeroizing<String>
