## Problem/Motivation The benchmark for the `ExpectPallet` XCM instruction uses a hard-coded version `4.0.0` for the `frame_system` pallet. Unfortunately, this doesn't work for the `polkadot-fellows/runtimes` repository, where we use dependencies from `crates.io`, e.g., [frame-system::23.0.0.0](https://github.com/polkadot-fellows/runtimes/blob/dd7f86f0d50064481ed0b7c0218494a5cfad997e/relay/kusama/Cargo.toml#L83). Closes: https://github.com/paritytech/polkadot-sdk/issues/2284 ## Solution This PR fixes the benchmarks that require pallet information and enables the runtime to provide the correct/custom pallet information. The default implementation provides `frame_system::Pallet` with index `0`, where the version is not hard-coded but read from the runtime. ## Local testing Added log for `T::valid_pallet` to the benchmarks like: ``` let valid_pallet = T::valid_pallet(); log::info!( target: "frame::benchmark::pallet", "valid_pallet: {}::{}::{}::{}::{}", valid_pallet.index, valid_pallet.module_name, valid_pallet.crate_version.major, valid_pallet.crate_version.minor, valid_pallet.crate_version.patch, ); ``` Run benchmarks for `westend`: ``` cargo run --bin=polkadot --features=runtime-benchmarks -- benchmark pallet --steps=2 --repeat=1 --extrinsic=* --heap-pages=4096 --json-file=./bench.json --chain=westend-dev --template=./polkadot/xcm/pallet-xcm-benchmarks/template.hbs --pallet=pallet_xcm_benchmarks::generic --output=./polkadot/runtime/westend/src/weights/xcm ``` --- For actual `frame_system` version: ``` [package] name = "frame-system" version = "4.0.0-dev" ``` Log dump: ``` 2023-11-13 12:56:45 Starting benchmark: pallet_xcm_benchmarks::generic::query_pallet 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 2023-11-13 12:56:45 Starting benchmark: pallet_xcm_benchmarks::generic::expect_pallet 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 2023-11-13 12:56:45 valid_pallet: 0::frame_system::4::0::0 ``` For changed `frame_system` version: ``` [package] name = "frame-system" version = "5.1.3-dev" ``` Log dump: ``` 2023-11-13 12:51:51 Starting benchmark: pallet_xcm_benchmarks::generic::query_pallet 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 2023-11-13 12:51:51 Starting benchmark: pallet_xcm_benchmarks::generic::expect_pallet 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 2023-11-13 12:51:51 valid_pallet: 0::frame_system::5::1::3 ``` ## References Closes: https://github.com/paritytech/polkadot-sdk/issues/2284
NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Polkadot, Kusama, Westend, and Rococo networks. In the future, these will be
relocated to the runtimes repository.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
