## Issue Addressed
Workaround for https://github.com/foundry-rs/foundry/issues/5115.

## Proposed Changes
Modifies the local testnet scripts to start a network with genesis validators embedded into the genesis state. This allows us to start a local testnet without the need for deploying a deposit contract or depositing validators pre-genesis.
This also enables us to start a local test network at any fork we want without going through fork transitions. Also adds scripts to start multiple geth clients and peer them with each other and peer the geth clients with beacon nodes to start a post merge local testnet.
## Additional info
Adds a new lcli command `mnemonics-validators` that generates validator directories derived from a given mnemonic.
Adds a new `derived-genesis-state` option to the `lcli new-testnet` command to generate a genesis state populated with validators derived from a mnemonic.

## Proposed Changes
Replace ganache-cli with anvil https://github.com/foundry-rs/foundry/blob/master/anvil/README.md
We can lose all js dependencies in CI as a consequence.
## Additional info
Also changes the ethers-rs version used in the execution layer (for the transaction reconstruction) to a newer one. This was necessary to get use the ethers utils for anvil. The fixed execution engine integration tests should catch any potential issues with the payload reconstruction after #3592

## Issue Addressed
The latest stable version (1.69.0) of Rust was released on 20 April and contains this change:
- [Update the minimum external LLVM to 14.](https://github.com/rust-lang/rust/pull/107573/)
This impacts some of our CI workflows (build and release-test-windows) that uses LLVM 13.0. This PR updates the workflows to install LLVM 15.0.
**UPDATE**: Also updated `h2` to address [this issue](https://github.com/advisories/GHSA-f8vr-r385-rh5r)
## Issue Addressed
There was a [`VecDeque` bug](https://github.com/rust-lang/rust/issues/108453) in some recent versions of the Rust standard library (1.67.0 & 1.67.1) that could cause Lighthouse to panic (reported by `@Sea Monkey` on discord). See full logs below.
The issue was likely introduced in Rust 1.67.0 and [fixed](https://github.com/rust-lang/rust/pull/108475) in 1.68, and we were able to reproduce the panic ourselves using [@michaelsproul's fuzz tests](https://github.com/michaelsproul/lighthouse/blob/fuzz-lru-time-cache/beacon_node/lighthouse_network/src/peer_manager/fuzz.rs#L111) on both Rust 1.67.0 and 1.67.1.
Users that uses our Docker images or binaries are unlikely affected, as our Docker images were built with `1.66`, and latest binaries were built with latest stable (`1.68.2`). It likely impacts user that builds from source using Rust versions 1.67.x.
## Proposed Changes
Bump Rust version (MSRV) to latest stable `1.68.2`.

## Proposed Changes
* Bump Go from 1.17 to 1.20. The latest Geth release v1.11.0 requires 1.18 minimum.
* Prevent a cache miss during payload building by using the right fee recipient. This prevents Geth v1.11.0 from building a block with 0 transactions. The payload building mechanism is overhauled in the new Geth to improve the payload every 2s, and the tests were failing because we were falling back on a `getPayload` call with no lookahead due to `get_payload_id` cache miss caused by the mismatched fee recipient. Alternatively we could hack the tests to send `proposer_preparation_data`, but I think the static fee recipient is simpler for now.
* Add support for optionally enabling Lighthouse logs in the integration tests. Enable using `cargo run --release --features logging/test_logger`. This was very useful for debugging.
## Proposed Changes
Another `tree-states` motivated PR, this adds `jemalloc` as the default allocator, with an option to use the system allocator by compiling with `FEATURES="" make`.

## Issue Addressed
Closes#3709
## Proposed Changes
Add the job `compile-with-beta-compiler` to `test-suite`. This job has the following steps:
1. Use `actions/checkout@v3`. (Needed to run make in a later step.)
2. Install the dependencies listed in [build from source guide](https://lighthouse-book.sigmaprime.io/installation-source.html).
3. Change the compiler to the current beta version with `rustup override`.
4. Run `make`.
## Issue Addressed

## Proposed Changes
* Replace `set-output` by `$GITHUB_OUTPUT` usage
* Avoid rate-limits when installing `protoc` by making authenticated requests (continuation of https://github.com/sigp/lighthouse/pull/3621)
* Upgrade all Ubuntu 18.04 usage to 22.04 (18.04 is end of life)
* Upgrade macOS-latest to explicit macOS-12 to silence warning
* Use `actions/checkout@v3` and `actions/cache@v3` to avoid deprecated NodeJS v12
## Additional Info
Can't silence the NodeJS warnings entirely due to https://github.com/sigp/lighthouse/issues/3705. Can fix that in future.

## Proposed Changes
Enable multiple database backends for the slasher, either MDBX (default) or LMDB. The backend can be selected using `--slasher-backend={lmdb,mdbx}`.
## Additional Info
In order to abstract over the two library's different handling of database lifetimes I've used `Box::leak` to give the `Environment` type a `'static` lifetime. This was the only way I could think of using 100% safe code to construct a self-referential struct `SlasherDB`, where the `OpenDatabases` refers to the `Environment`. I think this is OK, as the `Environment` is expected to live for the life of the program, and both database engines leave the database in a consistent state after each write. The memory claimed for memory-mapping will be freed by the OS and appropriately flushed regardless of whether the `Environment` is actually dropped.
We are depending on two `sigp` forks of `libmdbx-rs` and `lmdb-rs`, to give us greater control over MDBX OS support and LMDB's version.

## Proposed Changes
Make simulator merge compatible. Adds a `--post_merge` flag to the eth1 simulator that enables a ttd and simulates the merge transition. Uses the `MockServer` in the execution layer test utils to simulate a dummy execution node.
Adds the merge transition simulation to CI.
## Description
Add a new lint to CI that attempts to detect calls to functions like `block_on` from async execution contexts. This lint was written from scratch exactly for this purpose, on my fork of Clippy: https://github.com/michaelsproul/rust-clippy/tree/disallow-from-async
## Additional Info
- I've successfully detected the previous two issues we had with `block_on` by running the linter on the commits prior to each of these PRs: https://github.com/sigp/lighthouse/pull/3165, https://github.com/sigp/lighthouse/pull/3199.
- The lint runs on CI with `continue-on-error: true` so that if it fails spuriously it won't block CI.
- I think it would be good to merge this PR before https://github.com/sigp/lighthouse/pull/3244 so that we can lint the extensive executor-related changes in that PR.
- I aim to upstream the lint to Clippy, at which point building a custom version of Clippy from my fork will no longer be necessary. I imagine this will take several weeks or months though, because the code is currently a bit hacky and will need some renovations to pass review.
## Issue Addressed
This fixes the low-hanging Clippy lints introduced in Rust 1.61 (due any hour now). It _ignores_ one lint, because fixing it requires a structural refactor of the validator client that needs to be done delicately. I've started on that refactor and will create another PR that can be reviewed in more depth in the coming days. I think we should merge this PR in the meantime to unblock CI.
## Issue Addressed
Attempt to fix CI
## Proposed Changes
- ~~install `node-gyp-build` which should look for prebuilt binaries for `@truffle-suite/bigint_buffer`. This should make it so we don't have to build it directly. See: https://github.com/trufflesuite/ganache/pull/1414~~ this didn't work
- This also uses the `setup-node` action because it includes caching. Sort of a shot in the dark, but the ganache github repo uses it and the failures seem to be for missing files in a node cache

## Issue Addressed
Hopefully makes windows ganache installation more reliable.
## Proposed Changes
- use `chocolatey` to install windows build tools. This seems to often be the prescribed solution for `node gyp` issues. `chocolatey` is used here because `npm install --global --production windows-build-tools` hangs in github actions
## Additional Info
I still haven't found why the prior installation technique would sometimes work, the `windows-2019` environments seem to be identical across successes and failures. I think this should be re-run a few times to see if it can consistently pass
Co-authored-by: realbigsean <sean@sigmaprime.io>
## Proposed Changes
Set a minimum supported Rust version (MSRV) in the `Cargo.toml` for the Lighthouse binary so that attempts to compile it with an outdated compiler fail immediately with a clear error.
To ensure that the codebase builds with the MSRV I've also added a Github actions job that runs `cargo check` using the MSRV extracted from `Cargo.toml`. This will force us to keep it up to date.
I opted to use `cargo check` rather than Clippy because Clippy frequently introduces new lints that we adopt, so our MSRV for Clippy is usually the most recent Rust version, while the MSRV for building Lighthouse is older.
## Issue Addressed
As discussed on last-night's consensus call, the testnets next week will target the [Kiln Spec v2](https://hackmd.io/@n0ble/kiln-spec).
Presently, we support Kiln V1. V2 is backwards compatible, except for renaming `random` to `prev_randao` in:
- https://github.com/ethereum/execution-apis/pull/180
- https://github.com/ethereum/consensus-specs/pull/2835
With this PR we'll no longer be compatible with the existing Kintsugi and Kiln testnets, however we'll be ready for the testnets next week. I raised this breaking change in the call last night, we are all keen to move forward and break things.
We now target the [`merge-kiln-v2`](https://github.com/MariusVanDerWijden/go-ethereum/tree/merge-kiln-v2) branch for interop with Geth. This required adding the `--http.aauthport` to the tester to avoid a port conflict at startup.
### Changes to exec integration tests
There's some change in the `merge-kiln-v2` version of Geth that means it can't compile on a vanilla Github runner. Bumping the `go` version on the runner solved this issue.
Whilst addressing this, I refactored the `testing/execution_integration` crate to be a *binary* rather than a *library* with tests. This means that we don't need to run the `build.rs` and build Geth whenever someone runs `make lint` or `make test-release`. This is nice for everyday users, but it's also nice for CI so that we can have a specific runner for these tests and we don't need to ensure *all* runners support everything required to build all execution clients.
## More Info
- [x] ~~EF tests are failing since the rename has broken some tests that reference the old field name. I have been told there will be new tests released in the coming days (25/02/22 or 26/02/22).~~
## Issue Addressed
Timeouts due to Windows builds running for 2h 20m.
## Proposed Changes
* Increase Bors timeout to 3h
* Refine the target branch check so that it will pass when we make PRs to feature branches. This is just an extra change I've been meaning to sneak in for a while.
## Additional Info
* I think it would also be cool to try caching for CI again, but that's a separate issue and we'll still need the long timeout on a cache miss.
## Issue Addressed
NA
## Proposed Changes
This PR extends #3018 to address my review comments there and add automated integration tests with Geth (and other implementations, in the future).
I've also de-duplicated the "unused port" logic by creating an `common/unused_port` crate.
## Additional Info
I'm not sure if we want to merge this PR, or update #3018 and merge that. I don't mind, I'm primarily opening this PR to make sure CI works.

Being able to vendor the dependencies is important for archival and repdroducibility purpose.
It's also required to package lighthouse for some Linux distributions. Specifically [NixOS](https://nixos.org/) and [Yocto](https://www.yoctoproject.org/).

## Issue Addressed
Resolves#2069
## Proposed Changes
- Adds a `--doppelganger-detection` flag
- Adds a `lighthouse/seen_validators` endpoint, which will make it so the lighthouse VC is not interopable with other client beacon nodes if the `--doppelganger-detection` flag is used, but hopefully this will become standardized. Relevant Eth2 API repo issue: https://github.com/ethereum/eth2.0-APIs/issues/64
- If the `--doppelganger-detection` flag is used, the VC will wait until the beacon node is synced, and then wait an additional 2 epochs. The reason for this is to make sure the beacon node is able to subscribe to the subnets our validators should be attesting on. I think an alternative would be to have the beacon node subscribe to all subnets for 2+ epochs on startup by default.
## Additional Info
I'd like to add tests and would appreciate feedback.

## Issue Addressed
Windows incompatibility.
## Proposed Changes
On windows, lighthouse needs to default to STDIN as tty doesn't exist. Also Windows uses ACLs for file permissions. So to mirror chmod 600, we will remove every entry in a file's ACL and add only a single SID that is an alias for the file owner.
Beyond that, there were several changes made to different unit tests because windows has slightly different error messages as well as frustrating nuances around killing a process :/
## Additional Info
Tested on my Windows VM and it appears to work, also compiled & tested on Linux with these changes. Permissions look correct on both platforms now. Just waiting for my validator to activate on Prater so I can test running full validator client on windows.

## Proposed Changes
Add some caching to the test suite and to the aarch64 cross-compile in the docker build.
## Additional Info
Cache hits only occur if the Cargo.lock file is unchanged, Github Actions runner OS matches, and the cache is "in scope". Some documentation on github actions cache scoping is here:
https://docs.github.com/en/free-pro-team@latest/actions/guides/caching-dependencies-to-speed-up-workflows#matching-a-cache-key
I'm not sure how frequently we'll get cache hits, I imagine only on smaller PR's or updates to the same PR. And there is a cache size limit that we may end up reaching quickly. But Github actions handles evictions if we go over that limit.
Not sure how much of an impact this will end up having but I don't really see a downside to trying it out.

## Issue Addressed
Resolves#1100
## Proposed Changes
* Implement the `SafeArith` trait for `Slot` and `Epoch`, so that methods like `safe_add` become available.
* Tweak the `SafeArith` trait to allow a different `Rhs` type (analagous to `std::ops::Add`, etc).
* Add a `legacy-arith` feature to `types` and `state_processing` that conditionally enables implementations of
the `std` ops with saturating semantics.
* Check compilation of `types` and `state_processing` _without_ `legacy-arith` on CI,
thus guaranteeing that they only use the `SafeArith` primitives 🎉
## Additional Info
The `legacy-arith` feature gets turned on by all higher-level crates that depend on `state_processing` or `types`, thus allowing the beacon chain, networking, and other components to continue to rely on the availability of ops like `+`, `-`, `*`, etc.
**This is a consensus-breaking change**, but brings us in line with the spec, and our incompatibilities shouldn't have been reachable with any valid configuration of Eth2 parameters.

## Proposed Changes
- Refactor the `bls` crate to support multiple BLS "backends" (e.g., milagro, blst, etc).
- Removes some duplicate, unused code in `common/rest_types/src/validator.rs`.
- Removes the old "upgrade legacy keypairs" functionality (these were unencrypted keys that haven't been supported for a few testnets, no one should be using them anymore).
## Additional Info
Most of the files changed are just inconsequential changes to function names.
## TODO
- [x] Optimization levels
- [x] Infinity point: https://github.com/supranational/blst/issues/11
- [x] Ensure milagro *and* blst are tested via CI
- [x] What to do with unsafe code?
- [x] Test infinity point in signature sets
## Proposed Changes
CI is failing on PRs because of a regression in nightly Rust. This change forces `rustup` to install a version of the nightly compiler that can at least build `rustfmt`, which should reduce the frequency of this happening.
## Additional Info
Example failing run: https://github.com/sigp/lighthouse/runs/896694659
Alternatively, we could allow CI to succeed even when `cargo-udeps` fails, but I think we should avoid doing that unless we really have to.
## Issue Addressed
Prevent CI from succeeding when there are warnings. Code can still be built and tested with warnings locally, but CI may fail during a Rust update (which is fine IMO).
## Proposed Changes
* Deny warnings for all stable compiler jobs on CI (excludes `cargo udeps`, which runs under nightly)
* Fix the warnings currently on `master` related to unnecessary `mem::replace`
