To learn more about the basic module manager, click [here](../building-modules/module-manager.md#basicmanager). +- `InterfaceRegistry`: The `InterfaceRegistry` is used by the Protobuf codec to handle interfaces, which are encoded and decoded (we also say "unpacked") using [`google.protobuf.Any`](https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/any.proto). `Any` could be thought as a struct which contains a `type_url` (the concrete type of the interface) and a `value` (its encoded bytes). `InterfaceRegistry` provides a mechanism for registering interfaces and implementations that can be safely unpacked from `Any`. Each of the application's modules implements the `RegisterInterfaces` method, which can be used to register the module's own interfaces and implementations. + - To go more into details, the SDK uses an implementation of the Protobuf specification called [`gogoprotobuf`](https://github.com/gogo/protobuf). By default, the [gogo protobuf implementation of `Any`](https://godoc.org/github.com/gogo/protobuf/types) uses [global type registration](https://github.com/gogo/protobuf/blob/master/proto/properties.go#L540) to decode values packed in `Any` into concrete Go types. This introduces a vulnerability where any malicious module in the dependency tree could registry a type with the global protobuf registry and cause it to be loaded and unmarshaled by a transaction that referenced it in the `type_url` field. For more information, please refer to [ADR-019](../architecture/adr-019-protobuf-state-encoding.md). +- `Marshaler`: The `Marshaler` is the default codec used throughout the SDK. It is composed of a `BinaryMarshaler` used to encode and decode state, and a `JSONMarshaler` used to output data to the users (for example in the [CLI](#cli)). By default, the SDK uses Protobuf as `Marshaler`. +- `TxConfig`: `TxConfig` defines an interface a client can utilize to generate an application-defined concrete transaction type. Currently, the SDK handles two transaction types: `SIGN_MODE_DIRECT` (which uses Protobuf binary as over-the-wire encoding) and `SIGN_MODE_LEGACY_AMINO_JSON` (which depends on Amino). Read more about transactions [here](../core/transactions.md). +- `Amino`: Some legacy parts of the SDK still use Amino for backwards-compatibility. Each module exposes a `RegisterLegacyAmino` method to register the module's specific types within Amino. This `Amino` codec should not be used by app developers anymore, and will be removed in future releases. -See an example of a `MakeCodec` from [`gaia`](https://github.com/cosmos/gaia): - -+++ https://github.com/cosmos/gaia/blob/f41a660cdd5bea173139965ade55bd25d1ee3429/app/app.go#L64-L70 +The SDK exposes a `MakeCodecs` function used to create a `EncodingConfig`.

Therefore, the SDK provides a function `sdk.UnwrapSDKContext` to retrieve the `sdk.Context` from the provided +`context.Context`. + +Here's an example implementation for the bank module: + ++++ https://github.com/cosmos/cosmos-sdk/blob/d55c1a26657a0af937fa2273b38dcfa1bb3cff9f/x/bank/keeper/grpc_query.go + +### Legacy Queriers + +Module legacy `querier`s are typically implemented in a `./keeper/querier.go` file inside the module's folder. The [module manager](./module-manager.md) is used to add the module's `querier`s to the [application's `queryRouter`](../core/baseapp.md#query-routing) via the `NewQuerier()` method. Typically, the manager's `NewQuerier()` method simply calls a `NewQuerier()` method defined in `keeper/querier.go`, which looks like the following: + +```go +func NewQuerier(keeper Keeper) sdk.Querier { + return func(ctx sdk.Context, path []string, req abci.RequestQuery) ([]byte, error) { + switch path[0] { + case QueryType1: + return queryType1(ctx, path[1:], req, keeper) + + case QueryType2: + return queryType2(ctx, path[1:], req, keeper) + + default: + return nil, sdkerrors.Wrapf(sdkerrors.ErrUnknownRequest, "unknown %s query endpoint: %s", types.ModuleName, path[0]) + } + } +} +``` + +This simple switch returns a `querier` function specific to the type of the received `query`. At this point of the [query lifecycle](../interfaces/query-lifecycle.md), the first element of the `path` (`path[0]`) contains the type of the query. The following elements are either empty or contain arguments needed to process the query. + +The `querier` functions themselves are pretty straighforward. They generally fetch a value or values from the state using the [`keeper`](./keeper.md). Then, they marshall the value(s) using the [`codec`](../core/encoding.md) and return the `[]byte` obtained as result. + +For a deeper look at `querier`s, see this [example implementation of a `querier` function](https://github.com/cosmos/cosmos-sdk/blob/7f59723d889b69ca19966167f0b3a7fec7a39e53/x/gov/keeper/querier.go) from the bank module. + +## Next {hide} + +Learn about [`BeginBlocker` and `EndBlocker`](./beginblock-endblock.md) {hide} diff --git a/docs/building-modules/structure.md b/docs/building-modules/structure.md index 15e9c4bcede2..cdc2c6983c8c 100644 --- a/docs/building-modules/structure.md +++ b/docs/building-modules/structure.md @@ -27,6 +27,7 @@ x/{module} │   ├── keeper.go │   ├── ... │   └── querier.go +│   └── grpc_query.go ├── types │ ├── codec.go │ ├── errors.go @@ -36,10 +37,12 @@ x/{module} │ ├── keys.go │ ├── msgs.go │ ├── params.go -│ ├── types.pb.go │ ├── types.proto │ ├── ... │ └── querier.go +│ └── {module_name}.pb.go +│ └── query.pb.go +│ └── genesis.pb.go ├── simulation │   ├── decoder.go │   ├── genesis.go diff --git a/docs/core/baseapp.md b/docs/core/baseapp.md index beaba8b5e8b3..c4ea2c9faf08 100644 --- a/docs/core/baseapp.md +++ b/docs/core/baseapp.md @@ -200,7 +200,7 @@ The application's `router` is initilalized with all the routes using the applica ### Query Routing -Similar to `message`s, [`queries`](../building-modules/messages-and-queries.md#queries) need to be routed to the appropriate module's [querier](../building-modules/querier.md).
