konsti 5b27decbe7 Build backend: Add fast path (#9556) ... Going through PEP 517 to build a package is slow, so when building a package with the uv build backend, we can call into the uv build backend directly. This is the basis for the `uv build --list`. This does not enable the fast path for general source dependencies. There is a possible difference in execution if the latest uv version is newer than the one currently running: The PEP 517 path would use the latest version, while the fast path uses the current version. Please review commit-by-commit ### Benchmark `built_with_uv`, using the fast path: ``` $ hyperfine "~/projects/uv/target/profiling/uv build" Time (mean ± σ): 9.2 ms ± 1.1 ms [User: 4.6 ms, System: 4.6 ms] Range (min … max): 6.4 ms … 12.7 ms 290 runs ``` `hatcling_editable`, with hatchling being optimized for fast startup times: ``` $ hyperfine "~/projects/uv/target/profiling/uv build" Time (mean ± σ): 270.5 ms ± 18.4 ms [User: 230.8 ms, System: 44.5 ms] Range (min … max): 250.7 ms … 298.4 ms 10 runs ```		2024-12-02 15:37:50 +00:00
