Update `generate_makefile` to produce sensible error message in all
exceptional situations, instead of just some of them. These may surface
as one of the first things to someone getting started with the repo.
Annotate the `research` and `test` files for which no further changes
are needed to successfully compile them, to not interfere with periodic
tasks such as spec reference bumps.
`scanf` apparently has both a `bool` return as well as raising random
exceptions depending on what functions get called by the `macro`.
To make this explicit, catch the `ValueError` from the generated
`parseInt` call, to separate `scanf` behaviour from the actual SSZ
test logic. In the end, it mostly doesn't matter as there are some
`doAssert wasMatched` on the next line (not everywhere though).
But it still makes the `scanf` internals explicit, so is clearer.
Add `{.raises.}` annotations to `tests` files where needed to enable
`{.push raises: [].}`. Avoids interfering with periodic changes such as
spec version bumps, and avoids special casing folders when editing.
The effort to maintain `{.raises.}` is trivial after the initial round.
`test_peer_pool` is a bit different from the other tests as it uses
`closureScope` which doesn't play well with `{.push raises: [].}`.
Define an overload instead that allows passing `{.raises.}` to the
`template`. This allows using `unittest2`'s exception handler without
having to refactor the test.
Typically, mixing different versions of GitHub actions may lead to hard
to fix issues. As many libraries have been updated to use actions v4,
also bump our own `actions/checkout@v2`, `actions/checkout@v3`,
`actions/cache@v2` and `actions/cache@v3` to their `@v4` equivalents.
`stderr.write` may fail, e.g., if no tty is connected, which may happen
in some CI configurations. Discard such failures and continue quitting
instead of raising the error.
The exports in `eth2_discovery` produce deprecation warnings as they
refer to `close`, `closeWait` and so on. Turns out that they are not
necessary at all. The `Eth2DiscoveryProtocol` is even already exported
two lines above using `*` marker...
During refactoring of #5959, some implicit `return` were overlooked,
resulting in spurious `err()` being returned without message.

* add EIP-7044 support to keymanager API
When trying to sign `VoluntaryExit` via keymanager API, the logic is not
yet aware of EIP-7044 (part of Deneb). This patch adds missing EIP-7044
support to the keymanager API as well.
As part of this, the VC needs to become aware about:
- `CAPELLA_FORK_VERSION`: To correctly form the EIP-7044 signing domain.
The fork schedule does not indicate which of the results, if any,
corresponds to Capella.
- `CAPELLA_FORK_EPOCH`: To detect whether Capella was scheduled.
If a BN does not have it in its config while other BNs have it,
this leads to a log if Capella has not activated yet, or marks the BN
as incompatible if Capella already activated.
- `DENEB_FORK_EPOCH`: To check whether EIP-7044 logic should be used.
Related PRs:
- #5120 added support for processing EIP-7044 `VoluntaryExit` messages
as part of the state transition functions (tested by EF spec tests).
- #5953 synced the support from #5120 to gossip validation.
- #5954 added support to the `nimbus_beacon_node deposits exit` command.
- #5956 contains an alternative generic version of `VCForkConfig`.

In #5120, the `nimbus_beacon_node deposits exit` command was updated for
compatibility with EIP-7044, which forces signatures to be made using
`CAPELLA_FORK_VERSION` regardless of the `VoluntaryExit`'s `epoch` after
Deneb is activated.
This update had a regression, as an older mechanism was used to fetch
`RuntimeConfig`, resulting in an encoding issue (#5362). This was then
fixed in #5370, restoring general `deposits exit` functionality.
However, the logic from #5120 has another flaw, as it uses an incorrect
fork version based on the pre-Deneb logic even after Deneb and EIP-7044
are activated. Fix this now, so that `deposits exit` continues to work
correctly after Deneb activates.
In #5120, EIP-7044 support got added to the state transition function to
force `CAPELLA_FORK_VERSION` to be used when validiting `VoluntaryExit`
messages, irrespective of their `epoch`.
In #5637, similar logic was added when batch verifying BLS signatures,
which is used during gossip validation (libp2p gossipsub, and req/resp).
However, that logic did not match the one introduced in #5120, and only
uses `CAPELLA_FORK_VERSION` when a `VoluntaryExit`'s `epoch` was set to
a value `>= CAPELLA_FORK_EPOCH`. Otherwise, `BELLATRIX_FORK_VERSION`
would still be used when validating `VoluntaryExit`, e.g., with `epoch`
set to `0`, as is the case in this Holesky block:
- https://holesky.beaconcha.in/slot/1076985#voluntary-exits
Extracting the correct logic from #5120 into a function, and reusing it
when verifying BLS signatures fixes this issue, and also leverages the
exhaustive EF test suite that covers the (correct) #5120 logic.
This fix only affects networks that have EIP-7044 applied (post-Deneb).
Without the fix, Deneb blocks with a `VoluntaryExit` with `epoch` set to
`< CAPELLA_FORK_EPOCH` incorrectly fail to validate despite being valid.
Incorrect blocks that contain a malicious `VoluntaryExit` with `epoch`
set to `< CAPELLA_FORK_EPOCH` and signed using `BELLATRIX_FORK_VERSION`
_would_ pass the BLS verification stage, but subsequently fail the state
transition logic. Such blocks would still correctly be labeled invalid.
During refactoring of #5959, some implicit `return` were overlooked,
resulting in spurious `err()` being returned without message.

Fix regression from #5842 where `Eth-Execution-Payload-Value` is parsed
into `consensusValue` instead of `Eth-consensus-Block-Value`. We don't
use those values for now, but fixing avoids hard-to-debug bugs later.
