Electra ref-test alpha.9 update

[lucassaldanha]

PR Description

This PR has 3 fixes:

• Electra state upgrade
• Pending partial withdrawals
• Add missed exit checks to consolidation processing

Also, we are adding one reference test to the ignore list invalid_nonset_bits_for_one_committee to be fixed in a separate issue (#8892).

Another thing is we disabled fuzzConsolidationRequest_minimal on FuzzUtilTest. We will look at fixing it as part of #8876

Electra state upgrade

I found an issue with our calculation while running the latest reference tests. We were not taking into consideration when:
earliest_exit_epoch = compute_activation_exit_epoch(get_current_epoch(pre)) is greater than the max exitEpoch from our validator set.

The current change should match this:

earliest_exit_epoch = compute_activation_exit_epoch(get_current_epoch(pre))
    for validator in pre.validators:
        if validator.exit_epoch != FAR_FUTURE_EPOCH:
            if validator.exit_epoch > earliest_exit_epoch:
                earliest_exit_epoch = validator.exit_epoch
    earliest_exit_epoch += Epoch(

LGTM. This was a recent change by the way.

• Update initial earliest_exit_epoch calculation & add tests ethereum/consensus-specs#4001

Included in the alpha.9 release two weeks ago:

• https://github.com/ethereum/consensus-specs/releases/tag/v1.5.0-alpha.9

I suspect the reference tests are failing because Teku is using alpha.8 right now.

Also, the fact that you missed this was my fault. I missed including it in the release notes. See:

• Release v1.5.0-alpha.9 ethereum/consensus-specs#3982 (comment)

Correct. I'm working on the update to alpha9!
