Walkthrough

The Cosmos authz module has been updated to introduce a new feature for pruning expired grants. This includes a new PruneExpiredGrants RPC method, related message types, and updates to existing functions to handle a limit on the number of grants pruned per operation. The keeper logic, module behavior, and test cases have been updated accordingly. A new message type, MsgPruneExpiredGrants, is also added for maintenance purposes to automate the cleanup process.

Consider checking for errors when emitting events with EmitTypedEvent. Even though it's not common for this function to return an error, handling the error can be important for auditing and debugging purposes, ensuring that all events are emitted successfully or that failures are noted.

sdkCtx := sdk.UnwrapSDKContext(ctx)
if err := sdkCtx.EventManager().EmitTypedEvent(&authz.EventPruneExpiredGrants{Pruner: msg.Pruner}); err != nil {
    return nil, err
}
