Pylons Upgrades

This folder contains sub-folders for every pylons upgrade. It also defines upgrade structs, that each upgrade implements. These then get included in the application app.go to run the upgrade.

Version History

Upgrade types

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 upgrade struct, and then set it in the app.go. The app.go will then define the upgrade handler.

type Upgrade struct {
	// Upgrade version name, for the upgrade handler, e.g. `v7`
	UpgradeName string
	// Store upgrades, should be used for any new modules introduced, new modules deleted, or store names renamed.
	StoreUpgrades storetypes.StoreUpgrades
}
