Types

type BaseAppParamManager

type BaseAppParamManager interface {
	GetConsensusParams(ctx sdk.Context) *abci.ConsensusParams
	StoreConsensusParams(ctx sdk.Context, cp *abci.ConsensusParams)
}

BaseAppParamManager defines an interrace that BaseApp is expected to fullfil that allows upgrade handlers to modify BaseApp parameters.

type Upgrade

type Upgrade struct {
	// Upgrade version name, for the upgrade handler, e.g. `v3`
	UpgradeName string

	// CreateUpgradeHandler defines the function that creates an upgrade handler
	CreateUpgradeHandler func(*module.Manager, module.Configurator, BaseAppParamManager, *keepers.AppKeepers) 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.
