Struct polkadot_runtime_parachains::paras::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn force_set_current_code( origin: OriginFor<T>, para: ParaId, new_code: ValidationCode ) -> DispatchResult

Set the storage for the parachain validation code immediately.

pub fn force_set_current_head( origin: OriginFor<T>, para: ParaId, new_head: HeadData ) -> DispatchResult

Set the storage for the current parachain head data immediately.

pub fn force_schedule_code_upgrade( origin: OriginFor<T>, para: ParaId, new_code: ValidationCode, relay_parent_number: BlockNumberFor<T> ) -> DispatchResult

Schedule an upgrade as if it was scheduled in the given relay parent block.

pub fn force_note_new_head( origin: OriginFor<T>, para: ParaId, new_head: HeadData ) -> DispatchResult

Note a new block head for para within the context of the current block.

pub fn force_queue_action(origin: OriginFor<T>, para: ParaId) -> DispatchResult

Put a parachain directly into the next session’s action queue. We can’t queue it any sooner than this without going into the initializer…

pub fn add_trusted_validation_code( origin: OriginFor<T>, validation_code: ValidationCode ) -> DispatchResult

Adds the validation code to the storage.

The code will not be added if it is already present. Additionally, if PVF pre-checking is running for that code, it will be instantly accepted.

Otherwise, the code will be added into the storage. Note that the code will be added into storage with reference count 0. This is to account the fact that there are no users for this code yet. The caller will have to make sure that this code eventually gets used by some parachain or removed from the storage to avoid storage leaks. For the latter prefer to use the poke_unused_validation_code dispatchable to raw storage manipulation.

This function is mainly meant to be used for upgrading parachains that do not follow the go-ahead signal while the PVF pre-checking feature is enabled.

pub fn poke_unused_validation_code( origin: OriginFor<T>, validation_code_hash: ValidationCodeHash ) -> DispatchResult

Remove the validation code from the storage iff the reference count is 0.

This is better than removing the storage directly, because it will not remove the code that was suddenly got used by some parachain while this dispatchable was pending dispatching.

pub fn include_pvf_check_statement( origin: OriginFor<T>, stmt: PvfCheckStatement, signature: ValidatorSignature ) -> DispatchResultWithPostInfo

Includes a statement for a PVF pre-checking vote. Potentially, finalizes the vote and enacts the results if that was the last vote before achieving the supermajority.

pub fn force_set_most_recent_context( origin: OriginFor<T>, para: ParaId, context: BlockNumberFor<T> ) -> DispatchResult

Set the storage for the current parachain head data immediately.

impl<T: Config> Pallet<T>

pub fn upgrade_restriction_signal<KArg>(k: KArg) -> Option<UpgradeRestriction>where KArg: EncodeLike<ParaId>,

“ This is used by the relay-chain to communicate that there are restrictions for performing“ “ an upgrade for this parachain.“ “” “ This may be a because the parachain waits for the upgrade cooldown to expire. Another“ “ potential use case is when we want to perform some maintenance (such as storage migration)“ “ we could restrict upgrades to make the process simpler.“ “” “ NOTE that this field is used by parachains via merkle storage proofs, therefore changing“ “ the format will require migration of parachains.“
