Struct pallet_state_trie_migration::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn control_auto_migration( origin: OriginFor<T>, maybe_config: Option<MigrationLimits> ) -> DispatchResult

Control the automatic migration.

The dispatch origin of this call must be Config::ControlOrigin.

pub fn continue_migrate( origin: OriginFor<T>, limits: MigrationLimits, real_size_upper: u32, witness_task: MigrationTask<T> ) -> DispatchResultWithPostInfo

Continue the migration for the given limits.

The dispatch origin of this call can be any signed account.

This transaction has NO MONETARY INCENTIVES. calling it will not reward anyone. Albeit, Upon successful execution, the transaction fee is returned.

The (potentially over-estimated) of the byte length of all the data read must be provided for up-front fee-payment and weighing. In essence, the caller is guaranteeing that executing the current MigrationTask with the given limits will not exceed real_size_upper bytes of read data.

The witness_task is merely a helper to prevent the caller from being slashed or generally trigger a migration that they do not intend. This parameter is just a message from caller, saying that they believed witness_task was the last state of the migration, and they only wish for their transaction to do anything, if this assumption holds. In case witness_task does not match, the transaction fails.

Based on the documentation of MigrationTask::migrate_until_exhaustion, the recommended way of doing this is to pass a limit that only bounds count, as the size limit can always be overwritten.

pub fn migrate_custom_top( origin: OriginFor<T>, keys: Vec<Vec<u8>>, witness_size: u32 ) -> DispatchResultWithPostInfo

Migrate the list of top keys by iterating each of them one by one.

This does not affect the global migration process tracker (MigrationProcess), and should only be used in case any keys are leftover due to a bug.

pub fn migrate_custom_child( origin: OriginFor<T>, root: Vec<u8>, child_keys: Vec<Vec<u8>>, total_size: u32 ) -> DispatchResultWithPostInfo

Migrate the list of child keys by iterating each of them one by one.

All of the given child keys must be present under one child_root.

This does not affect the global migration process tracker (MigrationProcess), and should only be used in case any keys are leftover due to a bug.

pub fn set_signed_max_limits( origin: OriginFor<T>, limits: MigrationLimits ) -> DispatchResult

Set the maximum limit of the signed migration.

pub fn force_set_progress( origin: OriginFor<T>, progress_top: ProgressOf<T>, progress_child: ProgressOf<T> ) -> DispatchResult

Forcefully set the progress the running migration.

This is only useful in one case: the next key to migrate is too big to be migrated with a signed account, in a parachain context, and we simply want to skip it. A reasonable example of this would be :code:, which is both very expensive to migrate, and commonly used, so probably it is already migrated.

In case you mess things up, you can also, in principle, use this to reset the migration process.
