Nolus Upgrades

This folder contains sub-folders for every nolus upgrade. (Both state migrations, and hard forks) It also defines upgrade & hard fork structs, that each upgrade implements. These then get included in the application app.go to run the upgrade.

Version History

Upgrade types

Currently in Nolus we support only one upgrade type, Upgrade. If we need to support more upgrade types, like Fork, we can add them. An Upgrade defines an upgrade that is to be acted upon by state migrations from the SDK x/upgrade module.

type Upgrade struct {
 // Upgrade version name, for the upgrade handler, e.g. `v7`
 UpgradeName string
 // Function that creates an upgrade handler
 CreateUpgradeHandler func(mm *module.Manager, configurator module.Configurator, keepers *keepers.AppKeepers) upgradetypes.UpgradeHandler
 // Store upgrades, should be used for any new modules introduced, new modules deleted, or store names renamed.
 StoreUpgrades store.StoreUpgrades
}

// type Fork struct {
//  // Upgrade version name, for the upgrade handler, e.g. `v7`
//  UpgradeName string
//  // height the upgrade occurs at
//  UpgradeHeight int64

//  // Function that runs some custom state transition code at the beginning of a fork.
//  BeginForkLogic func(ctx sdk.Context, keepers *keepers.AppKeepers)
// }
