| # Classic Terra Upgrades | ||
|
|
||
| This folder contains sub-folders for every classic terra 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. | ||
|
|
||
| ## Upgrade History | ||
| ### v1 (core v1.0.x) | ||
| __NOTE__: initial version without upgrade handler | ||
| * (soft-fork) v0.5.20 - Disable swap and IBC [#760](https://github.com/terra-money/classic-core/pull/760) | ||
| * (soft-fork) v0.5.21 - Burn Tax and allow Luna to be taxed | ||
| * (soft-fork) v0.5.22 - Limit validator power to 20% [cosmos-sdk/pull/104](https://github.com/terra-money/cosmos-sdk/pull/104) | ||
| * (soft-fork) v0.5.23 - Enable IBC | ||
| * (soft-fork) v1.0.5 - Set module version map for enabling software upgrades | ||
| ### v2 (core v1.1.x) | ||
| * (treasury) Tax exemption list, burn tax split | ||
| ### v3 (core v2.0.x) | ||
| * (treasury) Minimum initial deposit for governance proposals | ||
| ### v4 (core v2.1.x) | ||
| * (staking) Minimum commision rate | ||
|
|
||
| ## Upgrade types | ||
|
|
||
| There are two upgrade types exposed, `Upgrade` and `Fork`. An `Upgrade` | ||
| defines an upgrade that is to be acted upon by state migrations from the | ||
| SDK `x/upgrade` module. A `Fork` defines a hard fork that changes some | ||
| logic at a block height. If the goal is to have a new binary be | ||
| compatible with the old binary prior to the upgrade height, as is the | ||
| case for all classic terra `Fork`s, then all logic changes must be | ||
| height-gated or in the `BeginForkLogic` code. | ||
|
|
||
| ```go | ||
| 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, keppers *keepers.AppKeepers, mm *module.Manager) | ||
| } | ||
| ``` |
