Beefy: add benchmarks for report_fork_voting() (#5188)
Browse files Browse the repository at this point in the history
Related to #4523 

This PR adds benchmarks for `report_fork_voting()`.

**Important: Even though the benchmarks are now available, we still use
`Weight::MAX`. That's because I realized while working on this PR that
there's still one missing piece. We should also check that the ancestry
proof is optimal. I plan to do this in a future PR, hopefully the last
one related to #4523.**

title: Added benchmarks for BEEFY fork voting

doc:
- audience:
- Runtime Dev
- Runtime User
description: |
This PR adds benchmarks for `report_fork_voting` and `report_future_voting` extrinsics to `pallet-beefy`.
`report_future_voting` can be called now. `report_fork_voting` can't be called yet. Even though we have added
the formula for computing its weight, we still use `Weight::MAX`. We will set the proper weight in a future PR.
In order to do this we need to also check that the ancestry proof is optimal.
The PR adds a `WeightInfo` associated trait to the `pallet_beefy_mmr::Config` and defines benchmarks for
`pallet_beefy_mmr`.
