Enum polkadot_primitives::v2::UpgradeGoAhead
source · pub enum UpgradeGoAhead {
Abort,
GoAhead,
}
Expand description
A struct that the relay-chain communicates to a parachain indicating what course of action the parachain should take in the coordinated parachain validation code upgrade process.
This data type appears in the last step of the upgrade process. After the parachain observes it and reacts to it the upgrade process concludes.
Variants§
Abort
Abort the upgrade process. There is something wrong with the validation code previously submitted by the parachain. This variant can also be used to prevent upgrades by the governance should an emergency emerge.
The expected reaction on this variant is that the parachain will admit this message and remove all the data about the pending upgrade. Depending on the nature of the problem (to be examined offchain for now), it can try to send another validation code or just retry later.
GoAhead
Apply the pending code change. The parablock that is built on a relay-parent that is descendant of the relay-parent where the parachain observed this signal must use the upgraded validation code.
