Pallet** provides an on-chain system to register and manage versions of DAC (Data Aggregation Component) WASM modules used by DDC clusters. + +## Overview + +This pallet enables governance to: +- Add new DAC versions without runtime upgrades +- Manage version lifecycles (activation, updates, deprecations) +- Maintain transparent, auditable history of all DAC versions + +Instead of embedding DAC logic directly into the runtime, the pallet stores DAC modules (WASM binaries) on-chain, making DAC logic modular, governance-controlled, and easily upgradeable. + +## Key Features + +- **Governance Controlled:** Only governance can register, update, or deprecate DAC versions +- **Single-Step Upload:** Full WASM file uploaded in one atomic transaction +- **Versioned Metadata:** Tracks API version, semantic version, and activation block +- **Dynamic Retrieval:** DDC and Inspector components fetch versions by hash +- **Auditable Lifecycle:** Every change and event stored on-chain +- **No Maintenance Needed:** No chunking, CLI, or cleanup process required + +## Storage + +| Storage Item | Type | Description | +| --- | --- | --- | +| `CodeByHash` | `Map` | Metadata for each DAC version | +| `WasmCode` | `Map` | Full DAC WASM binary | +| `Deregistered` | `Map` | Marks deprecated or disabled DAC versions | + +## Metadata Structure + +Each DAC version includes: +- **code_hash:** Unique blake2_256 hash of the WASM +- **api_version:** Major/minor compatibility identifier +- **semver:** Semantic version (e.g., `1.5.0`) +- **allowed_from:** Block number when the version becomes active +- **length:** Size of the WASM binary (bytes) + +## Extrinsics + +### `register_code` + +Registers a new DAC version on-chain. + +**Parameters:** +- `code`: The WASM binary code +- `api_version`: API version (major.minor) +- `semver`: Semantic version (major.minor.patch) +- `allowed_from`: Block number when this version becomes active + +**Origin:** Governance only + +### `update_meta` + +Updates metadata for an existing DAC version. + +**Parameters:** +- `code_hash`: Hash of the code to update +- `api_version`: New API version (major.minor) +- `semver`: New semantic version (major.minor.patch) +- `allowed_from`: New activation block + +**Origin:** Governance only + +### `deregister_code` + +Marks an existing DAC version as inactive or deprecated. + +**Parameters:** +- `code_hash`: Hash of the code to deregister + +**Origin:** Governance only + +## Events + +| Event | Description | +| --- | --- | +| `CodeRegistered` | A new DAC version was successfully registered | +| `CodeMetaUpdated` | Metadata of a DAC version was updated | +| `CodeDeregistered` | DAC version marked as inactive or deprecated | + +## Public Interface + +The pallet provides several public functions for querying the registry: + +- `get_code(code_hash)`: Get the WASM code for a given code hash +- `get_metadata(code_hash)`: Get the metadata for a given code hash +- `is_code_active(code_hash)`: Check if a code hash is active (exists and not deregistered) +- `is_code_ready(code_hash)`: Check if a code is ready for use (active and past activation block) + +## Configuration + +The pallet requires the following configuration: + +- `GovernanceOrigin`: Origin that can perform registry operations +- `MaxCodeSize`: Maximum size of a WASM code in bytes +- `WeightInfo`: Weight functions for benchmarking + +## Usage Example + +```rust +// Register a new DAC version +DacRegistry::register_code( + RuntimeOrigin::root(), + wasm_code, + (1, 0), // API version + (1, 0, 0), // Semantic version + 100, // Activation block +)?; + +// Check if code is ready +let code_hash = compute_code_hash(&wasm_code); +if DacRegistry::is_code_ready(code_hash) { + let code = DacRegistry::get_code(code_hash).unwrap(); + // Execute the DAC code +} +``` + +## Testing + +The pallet includes comprehensive tests covering: +- Successful registration and retrieval +- Input validation +- Error conditions +- Event emission +- Public interface functions +- Governance origin enforcement + +Run tests with: +```bash +cargo test -p pallet-dac-registry +``` + +## Benchmarking + +The pallet includes weight functions for benchmarking. Run benchmarks with: +```bash +cargo run --release --features runtime-benchmarks -- benchmark pallet --pallet=pallet_dac_registry --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 +``` diff --git a/pallets/dac-registry/src/benchmarking.rs b/pallets/dac-registry/src/benchmarking.rs new file mode 100644 index 000000000..ffa0afb60 --- /dev/null +++ b/pallets/dac-registry/src/benchmarking.rs @@ -0,0 +1,113 @@ +//!
