Adds a mechanism to reclaim proof size weight.
|
|
1. Introduces a new `SignedExtension` that reclaims the difference
|
|
between benchmarked proof size weight and actual consumed proof size weight.
|
|
2. Introduces a manual mechanism, `StorageWeightReclaimer`, to reclaim excess storage weight for situations
|
|
that require manual weight management. The most prominent case is the `on_idle` hook.
|
|
3. Adds the `storage_proof_size` host function to the PVF. Parachain nodes should add it to ensure compatibility.
|
|
|
|
To enable proof size reclaiming, add the host `storage_proof_size` host function to the parachain node. Add the
|
|
`StorageWeightReclaim` `SignedExtension` to your runtime and enable proof recording during block import.

This host function is used to pass the current size of the storage proof to the runtime.
|
|
It was introduced before but becomes relevant now.
|
|
Note: This host function is intended to be used through `cumulus_primitives_storage_weight_reclaim::get_proof_size`.
|
|
Direct usage is not recommended.
