## Issue Addressed
Related to: #2259
Made an attempt at all the necessary updates here to publish the crates to crates.io. I incremented the minor versions on all the crates that have been previously published. We still might run into some issues as we try to publish because I'm not able to test this out but I think it's a good starting point.
## Proposed Changes
- Add description and license to `ssz_types` and `serde_util`
- rename `serde_util` to `eth2_serde_util`
- increment minor versions
- remove path dependencies
- remove patch dependencies
## Additional Info
Crates published:
- [x] `tree_hash` -- need to publish `tree_hash_derive` and `eth2_hashing` first
- [x] `eth2_ssz_types` -- need to publish `eth2_serde_util` first
- [x] `tree_hash_derive`
- [x] `eth2_ssz`
- [x] `eth2_ssz_derive`
- [x] `eth2_serde_util`
- [x] `eth2_hashing`

## Proposed Changes
Add functionality in the validator monitor to provide sync committee related metrics for monitored validators.

## Issue Addressed
NA
## Proposed Changes
This PR adds some more fancy macro magic to make it easier to add a new built-in (aka "baked-in") testnet config to the `lighthouse` binary.
Previously, a user needed to modify several files and repeat themselves several times. Now, they only need to add a single definition in the `eth2_config` crate. No repetition 🎉
## Issue Addressed
Resolves#2487
## Proposed Changes
Logs a message once in every invocation of `Eth1Service::update` method if the primary endpoint is unavailable for some reason.
e.g.
```log
Aug 03 00:09:53.517 WARN Error connecting to eth1 node endpoint action: trying fallbacks, endpoint: http://localhost:8545/, service: eth1_rpc
Aug 03 00:09:56.959 INFO Fetched data from fallback fallback_number: 1, service: eth1_rpc
```
The main aim of this PR is to have an accompanying message to the "action: trying fallbacks" error message that is returned when checking the endpoint for liveness. This is mainly to indicate to the user that the fallback was live and reachable.
## Additional info
This PR is not meant to be a catch all for all cases where the primary endpoint failed. For instance, this won't log anything if the primary node was working fine during endpoint liveness checking and failed during deposit/block fetching. This is done intentionally to reduce number of logs while initial deposit/block sync and to avoid more complicated logic.

## Proposed Changes
Add the fork epoch for Altair on Prater: 36660
## Additional Info
This `config.yaml` is copied exactly from upstream. Large parts already matched due to our preemptive move to the new config style.
## Issue Addressed
NA
## Proposed Changes
- Version bump
- Increase queue sizes for aggregated attestations and re-queued attestations.
## Additional Info
NA
## Proposed Changes
* Consolidate Tokio versions: everything now uses the latest v1.10.0, no more `tokio-compat`.
* Many semver-compatible changes via `cargo update`. Notably this upgrades from the yanked v0.8.0 version of crossbeam-deque which is present in v1.5.0-rc.0
* Many semver incompatible upgrades via `cargo upgrades` and `cargo upgrade --workspace pkg_name`. Notable ommissions:
- Prometheus, to be handled separately: https://github.com/sigp/lighthouse/issues/2485
- `rand`, `rand_xorshift`: the libsecp256k1 package requires 0.7.x, so we'll stick with that for now
- `ethereum-types` is pinned at 0.11.0 because that's what `web3` is using and it seems nice to have just a single version
## Additional Info
We still have two versions of `libp2p-core` due to `discv5` depending on the v0.29.0 release rather than `master`. AFAIK it should be OK to release in this state (cc @AgeManning )
## Issue Addressed
NA
## Proposed Changes
- Bump to `v1.5.0-rc.0`.
- Increase attestation reprocessing queue size (I saw this filling up on Prater).
- Reduce error log for full attn reprocessing queue to warn.
## TODO
- [x] Manual testing
- [x] Resolve https://github.com/sigp/lighthouse/pull/2493
- [x] Include https://github.com/sigp/lighthouse/pull/2501
## Issue Addressed
- Resolves#2457
- Resolves#2443
## Proposed Changes
Target the (presently unreleased) head of `libp2p/rust-libp2p:master` in order to obtain the fix from https://github.com/libp2p/rust-libp2p/pull/2175.
Additionally:
- `libsecp256k1` needed to be upgraded to satisfy the new version of `libp2p`.
- There were also a handful of minor changes to `eth2_libp2p` to suit some interface changes.
- Two `cargo audit --ignore` flags were remove due to libp2p upgrades.

## Proposed Changes
Adds the Altair fork schedule for Pyrmont, as per https://github.com/eth2-clients/eth2-networks/pull/56 (credits to @ajsutton).
## Additional Info
- I've marked this as `do-not-merge` until the upstream PR is merged.
- I've tagged this for `v1.5.0` because I expect the upstream PR to be merged soon, and I think it would be great if v1.5.0 shipped fully ready for the Pyrmont fork.
## Proposed Changes
* Implement the validator client and HTTP API changes necessary to support Altair

## 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.

## Proposed Changes
- Removing a bunch of unnecessary references
- Updated `Error::VariantError` to `Error::Variant`
- There were additional enum variant lints that I ignored, because I thought our variant names were fine
- removed `MonitoredValidator`'s `pubkey` field, because I couldn't find it used anywhere. It looks like we just use the string version of the pubkey (the `id` field) if there is no index

## Issue Addressed

## Proposed Changes
This PR addresses two things:
1. Allows the `ValidatorMonitor` to work with Altair states.
1. Optimizes `altair::process_epoch` (see [code](https://github.com/paulhauner/lighthouse/blob/participation-cache/consensus/state_processing/src/per_epoch_processing/altair/participation_cache.rs) for description)
## Breaking Changes
The breaking changes in this PR revolve around one premise:
*After the Altair fork, it's not longer possible (given only a `BeaconState`) to identify if a validator had *any* attestation included during some epoch. The best we can do is see if that validator made the "timely" source/target/head flags.*
Whilst this seems annoying, it's not actually too bad. Finalization is based upon "timely target" attestations, so that's really the most important thing. Although there's *some* value in knowing if a validator had *any* attestation included, it's far more important to know about "timely target" participation, since this is what affects finality and justification.
For simplicity and consistency, I've also removed the ability to determine if *any* attestation was included from metrics and API endpoints. Now, all Altair and non-Altair states will simply report on the head/target attestations.
The following section details where we've removed fields and provides replacement values.
### Breaking Changes: Prometheus Metrics
Some participation metrics have been removed and replaced. Some were removed since they are no longer relevant to Altair (e.g., total attesting balance) and others replaced with gwei values instead of pre-computed values. This provides more flexibility at display-time (e.g., Grafana).
The following metrics were added as replacements:
- `beacon_participation_prev_epoch_head_attesting_gwei_total`
- `beacon_participation_prev_epoch_target_attesting_gwei_total`
- `beacon_participation_prev_epoch_source_attesting_gwei_total`
- `beacon_participation_prev_epoch_active_gwei_total`
The following metrics were removed:
- `beacon_participation_prev_epoch_attester`
- instead use `beacon_participation_prev_epoch_source_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.
- `beacon_participation_prev_epoch_target_attester`
- instead use `beacon_participation_prev_epoch_target_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.
- `beacon_participation_prev_epoch_head_attester`
- instead use `beacon_participation_prev_epoch_head_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.
The `beacon_participation_prev_epoch_attester` endpoint has been removed. Users should instead use the pre-existing `beacon_participation_prev_epoch_target_attester`.
### Breaking Changes: HTTP API
The `/lighthouse/validator_inclusion/{epoch}/{validator_id}` endpoint loses the following fields:
- `current_epoch_attesting_gwei` (use `current_epoch_target_attesting_gwei` instead)
- `previous_epoch_attesting_gwei` (use `previous_epoch_target_attesting_gwei` instead)
The `/lighthouse/validator_inclusion/{epoch}/{validator_id}` endpoint lose the following fields:
- `is_current_epoch_attester` (use `is_current_epoch_target_attester` instead)
- `is_previous_epoch_attester` (use `is_previous_epoch_target_attester` instead)
- `is_active_in_current_epoch` becomes `is_active_unslashed_in_current_epoch`.
- `is_active_in_previous_epoch` becomes `is_active_unslashed_in_previous_epoch`.
## Additional Info
NA
## TODO
- [x] Deal with total balances
- [x] Update validator_inclusion API
- [ ] Ensure `beacon_participation_prev_epoch_target_attester` and `beacon_participation_prev_epoch_head_attester` work before Altair

## Issue Addressed
Resolves#2313
## Proposed Changes
Provide `BeaconNodeHttpClient` with a dedicated `Timeouts` struct.
This will allow granular adjustment of the timeout duration for different calls made from the VC to the BN. These can either be a constant value, or as a ratio of the slot duration.
Improve timeout performance by using these adjusted timeout duration's only whenever a fallback endpoint is available.
Add a CLI flag called `use-long-timeouts` to revert to the old behavior.
## Additional Info
Additionally set the default `BeaconNodeHttpClient` timeouts to the be the slot duration of the network, rather than a constant 12 seconds. This will allow it to adjust to different network specifications.

## Proposed Changes
Implement the consensus changes necessary for the upcoming Altair hard fork.
## Additional Info
This is quite a heavy refactor, with pivotal types like the `BeaconState` and `BeaconBlock` changing from structs to enums. This ripples through the whole codebase with field accesses changing to methods, e.g. `state.slot` => `state.slot()`.

This updates some older dependencies to address a few cargo audit warnings.
The majority of warnings come from network dependencies which will be addressed in #2389.
This PR contains some minor dep updates that are not network related.

## Issue Addressed
Closes#1661
## Proposed Changes
Add a dummy package called `target_check` which gets compiled early in the build and fails if the target is 32-bit
## Additional Info
You can test the efficacy of this check with:
```
cross build --release --manifest-path lighthouse/Cargo.toml --target i686-unknown-linux-gnu
```
In which case this compilation error is shown:
```
error: Lighthouse requires a 64-bit CPU and operating system

## Issue Addressed
`make lint` failing on rust 1.53.0.
## Proposed Changes
1.53.0 updates
## Additional Info
I haven't figure out why yet, we were now hitting the recursion limit in a few crates. So I had to add `#![recursion_limit = "256"]` in a few places

## Proposed Changes
I've noticed some of the SigP Prater nodes struggling on v1.4.0-rc.0. I suspect this is due to the changes in #2296. Specifically, the trade-off which lowered the memory footprint whilst increasing runtime on some functions.
Presently, this PR is documenting my testing on Prater.
## Additional Info
NA
## Issue Addressed
NA
## Proposed Changes
Bump versions.
## Additional Info
This is not exactly the v1.4.0 release described in [Lighthouse Update #36](https://lighthouse.sigmaprime.io/update-36.html).
Whilst it contains:
- Beta Windows support
- A reduction in Eth1 queries
- A reduction in memory footprint
It does not contain:
- Altair
- Doppelganger Protection
- The remote signer
We have decided to release some features early. This is primarily due to the desire to allow users to benefit from the memory saving improvements as soon as possible.
## TODO
- [x] Wait for #2340, #2356 and #2376 to merge and then rebase on `unstable`.
- [x] Ensure discovery issues are fixed (see #2388)
- [x] Ensure https://github.com/sigp/lighthouse/pull/2382 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2383 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2384 is merged/removed.
- [ ] Double-check eth1 cache is carried between boots
## Issue Addressed
NA
## Proposed Changes
Reverts #2345 in the interests of getting v1.4.0 out this week. Once we have released that, we can go back to testing this again.
## Additional Info
NA
## Issue Addressed
#2282
## Proposed Changes
Reduce the outbound requests made to eth1 endpoints by caching the results from `eth_chainId` and `net_version`.
Further reduce the overall request count by increasing `auto_update_interval_millis` from `7_000` (7 seconds) to `60_000` (1 minute).
This will result in a reduction from ~2000 requests per hour to 360 requests per hour (during normal operation). A reduction of 82%.
## Additional Info
If an endpoint fails, its state is dropped from the cache and the `eth_chainId` and `net_version` calls will be made for that endpoint again during the regular update cycle (once per minute) until it is back online.

## Issue Addressed

## Proposed Changes
Modify the configuration of [GNU malloc](https://www.gnu.org/software/libc/manual/html_node/The-GNU-Allocator.html) to reduce memory footprint.
- Set `M_ARENA_MAX` to 4.
- This reduces memory fragmentation at the cost of contention between threads.
- Set `M_MMAP_THRESHOLD` to 2mb
- This means that any allocation >= 2mb is allocated via an anonymous mmap, instead of on the heap/arena. This reduces memory fragmentation since we don't need to keep growing the heap to find big contiguous slabs of free memory.
- ~~Run `malloc_trim` every 60 seconds.~~
- ~~This shaves unused memory from the top of the heap, preventing the heap from constantly growing.~~
- Removed, see: https://github.com/sigp/lighthouse/pull/2299#issuecomment-825322646
*Note: this only provides memory savings on the Linux (glibc) platform.*
## Additional Info
I'm going to close#2288 in favor of this for the following reasons:
- I've managed to get the memory footprint *smaller* here than with jemalloc.
- This PR seems to be less of a dramatic change than bringing in the jemalloc dep.
- The changes in this PR are strictly runtime changes, so we can create CLI flags which disable them completely. Since this change is wide-reaching and complex, it's nice to have an easy "escape hatch" if there are undesired consequences.
## TODO
- [x] Allow configuration via CLI flags
- [x] Test on Mac
- [x] Test on RasPi.
- [x] Determine if GNU malloc is present?
- I'm not quite sure how to detect for glibc.. This issue suggests we can't really: https://github.com/rust-lang/rust/issues/33244
- [x] Make a clear argument regarding the affect of this on CPU utilization.
- [x] Test with higher `M_ARENA_MAX` values.
- [x] Test with longer trim intervals
- [x] Add some stats about memory savings
- [x] Remove `malloc_trim` calls & code
## 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.

## Issue Addressed
N/A
## Proposed Changes
Add unit tests for the various CLI flags associated with the beacon node and validator client. These changes require the addition of two new flags: `dump-config` and `immediate-shutdown`.
## Additional Info
Both `dump-config` and `immediate-shutdown` are marked as hidden since they should only be used in testing and other advanced use cases.
**Note:** This requires changing `main.rs` so that the flags can adjust the program behavior as necessary.

## Issue Addressed
#2276
## Proposed Changes
Add the `SensitiveUrl` struct which wraps `Url` and implements custom `Display` and `Debug` traits to redact user secrets from being logged in eth1 endpoints, beacon node endpoints and metrics.
## Additional Info
This also includes a small rewrite of the eth1 crate to make requests using `Url` instead of `&str`.
Some error messages have also been changed to remove `Url` data.
## Issue Addressed
None
## Proposed Changes
Adds support for downloading the deposit contract from a different location
by setting the environement variables `LIGHTHOUSE_DEPOSIT_CONTRACT_SPEC_URL`
and `LIGHTHOUSE_DEPOSIT_CONTRACT_TESTNET_URL`.
It also adds support to fetch the content from a local file:// URL.
This allows pre fetching to build in an environment without network access.
## Additional Info
Being able to build without network access is required to package the application for https://nixos.org/. But I imagine it might be useful for other distributions too.
## Issue Addressed
NA
## Proposed Changes
Bump versions.
## Additional Info
This is a minor release (not patch) due to the very slight change introduced by #2291.
## Issue Addressed
NA
## Proposed Changes
- Adds a specific log and metric for when a block is enshrined as head with a delay that will caused bad attestations
- We *technically* already expose this information, but it's a little tricky to determine during debugging. This makes it nice and explicit.
- Fixes a minor reporting bug with the validator monitor where it was expecting agg. attestations too early (at half-slot rather than two-thirds-slot).
## Additional Info
NA
## Issue Addressed
Closes#2274
## Proposed Changes
* Modify the `YamlConfig` to collect unknown fields into an `extra_fields` map, instead of failing hard.
* Log a debug message if there are extra fields returned to the VC from one of its BNs.
This restores Lighthouse's compatibility with Teku beacon nodes (and therefore Infura)
## Issue Addressed
#2224
## Proposed Changes
Add a `--password-file` option to the `lighthouse account validator import` command. The flag requires `--reuse-password` and will copy the password over to the `validator_definitions.yml` file. I used #2070 as a guide for validating the password as UTF-8 and stripping newlines.
