## Summary This PR removes the `ImportMap` implementation and all its routing through ruff. The import map was added in https://github.com/astral-sh/ruff/pull/3243 but we then never ended up using it to do cross file analysis. We are now working on adding multifile analysis to ruff, and revisit import resolution as part of it. ``` hyperfine --warmup 10 --runs 20 --setup "./target/release/ruff clean" \ "./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I" \ "./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I" Benchmark 1: ./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I Time (mean ± σ): 37.6 ms ± 0.9 ms [User: 52.2 ms, System: 63.7 ms] Range (min … max): 35.8 ms … 39.8 ms 20 runs Benchmark 2: ./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I Time (mean ± σ): 36.0 ms ± 0.7 ms [User: 50.3 ms, System: 58.4 ms] Range (min … max): 34.5 ms … 37.6 ms 20 runs Summary ./target/release/ruff-import check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I ran 1.04 ± 0.03 times faster than ./target/release/ruff check crates/ruff_linter/resources/test/cpython -e -s --extend-select=I ``` I suspect that the performance improvement should even be more significant for users that otherwise don't have any diagnostics. ``` hyperfine --warmup 10 --runs 20 --setup "cd ../ecosystem/airflow && ../../ruff/target/release/ruff clean" \ "./target/release/ruff check ../ecosystem/airflow -e -s --extend-select=I" \ "./target/release/ruff-import check ../ecosystem/airflow -e -s --extend-select=I" Benchmark 1: ./target/release/ruff check ../ecosystem/airflow -e -s --extend-select=I Time (mean ± σ): 53.7 ms ± 1.8 ms [User: 68.4 ms, System: 63.0 ms] Range (min … max): 51.1 ms … 58.7 ms 20 runs Benchmark 2: ./target/release/ruff-import check ../ecosystem/airflow -e -s --extend-select=I Time (mean ± σ): 50.8 ms ± 1.4 ms [User: 50.7 ms, System: 60.9 ms] Range (min … max): 48.5 ms … 55.3 ms 20 runs Summary ./target/release/ruff-import check ../ecosystem/airflow -e -s --extend-select=I ran 1.06 ± 0.05 times faster than ./target/release/ruff check ../ecosystem/airflow -e -s --extend-select=I ``` ## Test Plan `cargo test` |
