2024-09-20perf(ext/web): optimize performance.measure() (#25774)carles escrig royo
This PR optimizes the case when `performance.measure()` needs to find the startMark by name. It is a simple change on `findMostRecent` fn to avoiding copying and reversing the complete entries list. Adds minor missing tests for: - `clearMarks()`, general - `clearMeasures()`, general - `measure()`, case when the startMarks name exists more than once ### Benchmarks #### main ``` CPU | AMD Ryzen 7 PRO 6850U with Radeon Graphics Runtime | Deno 2.0.0-rc.4 (x86_64-unknown-linux-gnu) benchmark time/iter (avg) iter/s (min … max) p75 p99 p995 ---------------------- ----------------------------- --------------------- -------------------------- worst case measure() 2.1 ms 486.9 ( 1.7 ms … 2.4 ms) 2.2 ms 2.4 ms 2.4 ms ``` #### this PR ``` CPU | AMD Ryzen 7 PRO 6850U with Radeon Graphics Runtime | Deno 2.0.0-rc.4 (x86_64-unknown-linux-gnu) benchmark time/iter (avg) iter/s (min … max) p75 p99 p995 ---------------------- ----------------------------- --------------------- -------------------------- worst case measure() 966.3 µs 1,035 (876.9 µs … 1.1 ms) 1.0 ms 1.1 ms 1.1 ms ``` ```ts Deno.bench("worst case measure()", (b) => { performance.mark('start'); for (let i = 0; i < 1e5; i += 1) { performance.mark(crypto.randomUUID()); } b.start(); performance.measure('total', 'start'); b.end(); performance.clearMarks(); performance.clearMeasures(); }); ```
2024-09-03BREAKING(permissions): remove --allow-hrtime (#25367)Luca Casonato
Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because it is already possible to get access to high resolution timers through workers and SharedArrayBuffer. Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
2024-02-10chore: move cli/tests/ -> tests/ (#22369)Matt Mastracci
This looks like a massive PR, but it's only a move from cli/tests -> tests, and updates of relative paths for files. This is the first step towards aggregate all of the integration test files under tests/, which will lead to a set of integration tests that can run without the CLI binary being built. While we could leave these tests under `cli`, it would require us to keep a more complex directory structure for the various test runners. In addition, we have a lot of complexity to ignore various test files in the `cli` project itself (cargo publish exclusion rules, autotests = false, etc). And finally, the `tests/` folder will eventually house the `test_ffi`, `test_napi` and other testing code, reducing the size of the root repo directory. For easier review, the extremely large and noisy "move" is in the first commit (with no changes -- just a move), while the remainder of the changes to actual files is in the second commit.
