The `cdylib` was used for the pyo3 bindings to uv-pep508, which don't exist anymore. It was now creating warnings on musl due to musl (statically linked) no supporting shared libraries.
The uv-performance-memory-allocator is currently optimized out at least on musl due to the crate being otherwise unused (rust-lang/rust#64402), causing musl to not use jemalloc and being slow. Command: ``` cargo build --target x86_64-unknown-linux-musl --profile profiling hyperfine --warmup 1 --runs 10 --prepare "uv venv -p 3.12" "target/x86_64-unknown-linux-musl/profiling/uv pip compile scripts/requirements/airflow.in" ``` Before: ``` Time (mean ± σ): 1.149 s ± 0.013 s [User: 1.498 s, System: 0.433 s] Range (min … max): 1.131 s … 1.173 s 10 runs ``` After: ``` Time (mean ± σ): 552.6 ms ± 4.7 ms [User: 771.7 ms, System: 197.5 ms] Range (min … max): 546.4 ms … 561.6 ms 10 runs ```
