Types

type Upgrade

type Upgrade struct {
	// Upgrade version name, for the upgrade handler, e.g. `v7`
	UpgradeName string

	// CreateUpgradeHandler defines the function that creates an upgrade handler
	CreateUpgradeHandler func(*module.Manager, module.Configurator, *UpgradeKeepers) upgradetypes.UpgradeHandler

	// Store upgrades, should be used for any new modules introduced, new modules deleted, or store names renamed.
	StoreUpgrades store.StoreUpgrades
}

Upgrade defines a struct containing necessary fields that a SoftwareUpgradeProposal must have written, in order for the state migration to go smoothly. An upgrade must implement this struct, and then set it in the app.go. The app.go will then define the handler.

type UpgradeKeepers

type UpgradeKeepers struct {
	// keepers
	IcqKeeper          icqkeeper.Keeper
	CronKeeper         cronkeeper.Keeper
	TokenFactoryKeeper *tokenfactorykeeper.Keeper
	FeeBurnerKeeper    *feeburnerkeeper.Keeper
	SlashingKeeper     slashingkeeper.Keeper
	ParamsKeeper       paramskeeper.Keeper
	// subspaces
	GlobalFeeSubspace paramtypes.Subspace
}
