Upgrading Replicated Security

This guide provides instructions for upgrading to specific versions of Replicated Security.

v3.0.x

Upgrading to Cosmos SDK 0.47

The following should be considered as complementary to Cosmos SDK v0.47 UPGRADING.md.

Protobuf

Protobuf code generation, linting and formatting have been updated to leverage the ghcr.io/cosmos/proto-builder:0.11.5 docker container. Replicated Security protobuf definitions are now packaged and published to buf.build/cosmos/interchain-security via CI workflows. The third_party/proto directory has been removed in favour of dependency management using buf.build.

App modules

Legacy APIs of the AppModule interface have been removed from ccv modules. For example, for

- // Route implements the AppModule interface
- func (am AppModule) Route() sdk.Route {
-     return sdk.Route{}
- }
-
- // QuerierRoute implements the AppModule interface
- func (AppModule) QuerierRoute() string {
-     return types.QuerierRoute
- }
-
- // LegacyQuerierHandler implements the AppModule interface
- func (am AppModule) LegacyQuerierHandler(*codec.LegacyAmino) sdk.Querier {
-     return nil
- }
-
- // ProposalContents doesn't return any content functions for governance proposals.
- func (AppModule) ProposalContents(_ module.SimulationState) []simtypes.WeightedProposalContent {
-     return nil
- }

Imports

Imports for ics23 have been updated as the repository have been migrated from confio to cosmos.

import (
    // ...
-   ics23 "github.com/confio/ics23/go"
+   ics23 "github.com/cosmos/ics23/go"
    // ...
)

Imports for gogoproto have been updated.

import (
    // ...
-   "github.com/gogo/protobuf/proto"
+   "github.com/cosmos/gogoproto/proto"
    // ...
)

v2.0.x

Provider

Upgrading a provider from v1.1.0-multiden to v2.0.0 will require state migrations. See migration.go. See the provider module's ConsensusVersion in module.

Consumer

Upgrading a consumer from v1.2.0-multiden to v2.0.0 will NOT require state migrations. See the consumer module's ConsensusVersion in module.
