* Init `RuntimeLogger` automatically for each runtime api call This pr change the runtime api in such a way to always and automatically enable the `RuntimeLogger`. This enables the user to use `log` or `tracing` from inside the runtime to create log messages. As logging introduces some extra code and especially increases the size of the wasm blob. It is advised to disable all logging completely with `sp-api/disable-logging` when doing the wasm builds for the on-chain wasm runtime. Besides these changes, the pr also brings most of the logging found in frame to the same format "runtime::*". * Update frame/im-online/src/lib.rs Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com> * Update test-utils/runtime/Cargo.toml * Fix test * Don't use tracing in the runtime, as we don't support it :D * Fixes Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com>
Executive Module
The Executive module acts as the orchestration layer for the runtime. It dispatches incoming extrinsic calls to the respective modules in the runtime.
Overview
The executive module is not a typical pallet providing functionality around a specific feature. It is a cross-cutting framework component for the FRAME. It works in conjunction with the FRAME System module to perform these cross-cutting functions.
The Executive module provides functions to:
- Check transaction validity.
- Initialize a block.
- Apply extrinsics.
- Execute a block.
- Finalize a block.
- Start an off-chain worker.
Implementations
The Executive module provides the following implementations:
ExecuteBlock: Trait that can be used to execute a block.Executive: Type that can be used to make the FRAME available from the runtime.
Usage
The default Substrate node template declares the Executive type in its library.
Example
Executive type declaration from the node template.
#
/// Executive: handles dispatch to the various modules.
pub type Executive = executive::Executive<Runtime, Block, Context, Runtime, AllModules>;
Custom OnRuntimeUpgrade logic
You can add custom logic that should be called in your runtime on a runtime upgrade. This is done by setting an optional generic parameter. The custom logic will be called before the on runtime upgrade logic of all modules is called.
#
struct CustomOnRuntimeUpgrade;
impl frame_support::traits::OnRuntimeUpgrade for CustomOnRuntimeUpgrade {
fn on_runtime_upgrade() -> frame_support::weights::Weight {
// Do whatever you want.
0
}
}
pub type Executive = executive::Executive<Runtime, Block, Context, Runtime, AllModules, CustomOnRuntimeUpgrade>;
