feat: `pop bench pallet` logic implementation #407

chungquantin · 2025-02-11T08:40:47Z

Features

Add a new pop-cli command bench to benchmark pallets & parachain.
Integrates with frame-benchmarking-cli as a subcommand.
Run benchmarking on pallets without node binary required. Only runtime needed, inspired by FRAME Omni Bencher.
Locate the runtime WASM binary in the project and trigger runtime build - PR: feat: benchmark existing <runtime-name>.wasm or trigger build if needed #411
Nice to have: Support both benchmarking with chain spec and runtime. FRAME Omni Bencher only support benchmarking with runtime wasm. This addition enhances the user experience by allowing the developers to provide either the chain spec file path or the runtime wasm file.

How to test?

Use the below command in your pop-cli project to benchmark the base_parachain.wasm.

cargo run -- bench pallet --runtime=./crates/pop-cli/test-resources/base_parachain.wasm --pallet=pallet_timestamp --extrinsic= --output=./weights.rs

Or run a command pop bench pallet

Benchmarking completed successfully

Benchmark a pallet or parachain

Usage: pop bench
       pop bench <COMMAND>

Commands:
  pallet  Benchmark the extrinsics of FRAME Pallets
  help    Print this message or the help of the given subcommand(s)

To run benchmarking, builds the parachain runtime and specify the runtime path with --runtime

@AlexD10S CI fails but the PR is good for a review.

AlexD10S

Great work! The implementation is clean, and I love seeing how you're already handling the UI testing.

I’ve left some comments on areas for improvement, along with a couple of additional tests that could help improve coverage.

One refactor I want to see: In the rest of the commands, we typically separate the core logic (handled in pop_contracts or pop_parachain) from the "frontend logic" (pop-cli crate). In this PR, the logic is just cmd.run_with_spec, but it might be worth following the same approach by adding a generate_benchmarks(cmd) function in pop_parachain crate to handle this logic.

Nice! I should have done this refactor a while ago
