Additionally, 3 doctest diffs were found. These are ignored, as they are noisy.

Job group index

Test dashboard

Run

cargo run --manifest-path src/ci/citool/Cargo.toml -- \
test-dashboard 5f666a6ec939f64d862da5af7ad5be967916390c --output-dir test-dashboard

And then open test-dashboard/index.html in your browser to see an overview of all executed tests.

Job duration changes

  1. pr-check-1: 1508.5s -> 2549.4s (+69.0%)
  2. dist-apple-various: 3260.7s -> 5046.1s (+54.8%)
  3. x86_64-rust-for-linux: 2856.1s -> 4160.1s (+45.7%)
  4. x86_64-gnu-debug: 7039.1s -> 10143.7s (+44.1%)
  5. armhf-gnu: 4719.5s -> 6693.1s (+41.8%)
  6. x86_64-gnu-tools: 3461.1s -> 4881.6s (+41.0%)
  7. aarch64-gnu-debug: 4217.9s -> 5871.7s (+39.2%)
  8. x86_64-gnu-gcc: 3159.3s -> 4389.4s (+38.9%)
  9. pr-check-2: 2364.1s -> 3160.3s (+33.7%)
  10. arm-android: 5780.6s -> 7492.2s (+29.6%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.

How to interpret the job duration changes?
Job durations can vary a lot, based on the actual runner instance

that executed the job, system noise, invalidated caches, etc. The table above is provided

mostly for t-infra members, for simpler debugging of potential CI slow-downs.

How to interpret the job duration changes?
Job durations can vary a lot, based on the actual runner instance

that executed the job, system noise, invalidated caches, etc. The table above is provided

mostly for t-infra members, for simpler debugging of potential CI slow-downs.

Job durations can vary a lot, based on the actual runner instance

that executed the job, system noise, invalidated caches, etc. The table above is provided

mostly for t-infra members, for simpler debugging of potential CI slow-downs.
