What is this?

This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing 4931e09 (parent) -> 2fd6efc (this PR)

Test differences

Show 2 test diffs

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

Test dashboard

Run

cargo run --manifest-path src/ci/citool/Cargo.toml -- \
    test-dashboard 2fd6efc32704647e64d3d646d21c4c68eae100e4 --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

aarch64-apple: 10378.8s -> 7621.4s (-26.6%)
pr-check-1: 2058.5s -> 1709.5s (-17.0%)
dist-aarch64-apple: 8780.3s -> 7341.7s (-16.4%)
x86_64-rust-for-linux: 3178.0s -> 2668.8s (-16.0%)
aarch64-gnu-llvm-20-2: 3351.3s -> 2827.8s (-15.6%)
test-various: 7747.7s -> 6740.3s (-13.0%)
dist-apple-various: 4201.3s -> 4731.5s (+12.6%)
x86_64-gnu-tools: 3733.4s -> 3272.8s (-12.3%)
x86_64-gnu-aux: 7543.6s -> 6711.6s (-11.0%)
x86_64-gnu-gcc: 3387.3s -> 3019.1s (-10.9%)

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.

Do you know when this will be available with rustup by any chance? :3

Kobzol · 2026-01-14T15:10:56Z

Once we add it there 😆 One more PR is needed, to add libgccjit and cg_gcc to the "build manifest". I'll send it once I can find a bit of time.
