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.
In Nim 2.0, the `test_fixture_operations` files fail to compile with:
```
Error: 'result' is of type <Result[system.void, system.cstring]> which cannot be captured as it would violate memory safety, declared here: /nimbus-eth2/tests/consensus_spec/bellatrix/test_fixture_operations.nim(130, 5); using '-d:nimNoLentIterators' helps in some cases. Consider using a <ref Result[system.void, system.cstring]> which can be captured.
```
Wrapping the `applyExecutionPayload` in a factory that takes `path`
avoids this problem.
Suite names were not being used because `test` has to have access to it
during instantiation - this PR cleans things up a little while at the
same time upgrading unittest2.
This PR removes a few hundred thousand temporary seq allocations during
state transition - in particular, the flag seq was allocated per
validator while committees are computed per attestation.
* require sync committee supermajority in CI
To better catch problems with sync committee messages in CI, extend
local testnet simulation to also verify that each block is signed
by a supermajority of the sync committee.
Requires #5083 and #5084
* lint
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.
The former are tagged with static assert for `LightClientDataFork.high`.
The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.
Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.
* consolidate consensus spec transition test fixtures
* include capella
* consoliate fork test fixtures
* note change in EIP-4844 process_block in alpha.2
