Seems to be stuck building LLVM, probably because the caches being reset because this is an LLVM upgrade.
Let's keep this running so we can get as much stuff into cache as possible

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 3f98535 (parent) -> 1ed4882 (this PR)

Test differences

Show 1 test diff

Stage 2

  • [run-make] tests/run-make/compressed-debuginfo-zstd: pass -> ignore (ignored if LLVM wasn't build with zstd for ELF section compression or LLVM is not the default codegen backend) (J0)

Job group index

Test dashboard

Run

cargo run --manifest-path src/ci/citool/Cargo.toml -- \
test-dashboard 1ed488274bec5bf5cfe6bf7a1cc089abcc4ebd68 --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: 27m 5s -> 41m 29s (+53.2%)
  2. pr-check-2: 37m 31s -> 54m 44s (+45.9%)
  3. x86_64-rust-for-linux: 45m 48s -> 1h 3m (+37.8%)
  4. dist-aarch64-linux: 1h 50m -> 2h 28m (+35.2%)
  5. x86_64-gnu-stable: 2h 3m -> 2h 39m (+29.1%)
  6. x86_64-gnu-tools: 56m 55s -> 1h 12m (+27.0%)
  7. x86_64-gnu-gcc: 1h 2m -> 1h 16m (+23.3%)
  8. x86_64-gnu-miri: 1h 14m -> 1h 31m (+23.1%)
  9. arm-android: 1h 37m -> 1h 59m (+23.0%)
  10. x86_64-gnu-nopt: 2h 25m -> 2h 58m (+22.7%)
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 duration changes
  1. pr-check-1: 27m 5s -> 41m 29s (+53.2%)
  2. pr-check-2: 37m 31s -> 54m 44s (+45.9%)
  3. x86_64-rust-for-linux: 45m 48s -> 1h 3m (+37.8%)
  4. dist-aarch64-linux: 1h 50m -> 2h 28m (+35.2%)
  5. x86_64-gnu-stable: 2h 3m -> 2h 39m (+29.1%)
  6. x86_64-gnu-tools: 56m 55s -> 1h 12m (+27.0%)
  7. x86_64-gnu-gcc: 1h 2m -> 1h 16m (+23.3%)
  8. x86_64-gnu-miri: 1h 14m -> 1h 31m (+23.1%)
  9. arm-android: 1h 37m -> 1h 59m (+23.0%)
  10. x86_64-gnu-nopt: 2h 25m -> 2h 58m (+22.7%)
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.

Seems to be stuck building LLVM, probably because the caches being reset because this is an LLVM upgrade.

Let's keep this running so we can get as much stuff into cache as possible

Seems to be stuck building LLVM, probably because the caches being reset because this is an LLVM upgrade.

Let's keep this running so we can get as much stuff into cache as possible

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 3f98535 (parent) -> 1ed4882 (this PR)
Test differences
Show 1 test diff

Stage 2
  • [run-make] tests/run-make/compressed-debuginfo-zstd: pass -> ignore (ignored if LLVM wasn't build with zstd for ELF section compression or LLVM is not the default codegen backend) (J0)
Job group index
Test dashboard
Run
cargo run --manifest-path src/ci/citool/Cargo.toml -- \
test-dashboard 1ed488274bec5bf5cfe6bf7a1cc089abcc4ebd68 --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: 27m 5s -> 41m 29s (+53.2%)
  2. pr-check-2: 37m 31s -> 54m 44s (+45.9%)
  3. x86_64-rust-for-linux: 45m 48s -> 1h 3m (+37.8%)
  4. dist-aarch64-linux: 1h 50m -> 2h 28m (+35.2%)
  5. x86_64-gnu-stable: 2h 3m -> 2h 39m (+29.1%)
  6. x86_64-gnu-tools: 56m 55s -> 1h 12m (+27.0%)
  7. x86_64-gnu-gcc: 1h 2m -> 1h 16m (+23.3%)
  8. x86_64-gnu-miri: 1h 14m -> 1h 31m (+23.1%)
  9. arm-android: 1h 37m -> 1h 59m (+23.0%)
  10. x86_64-gnu-nopt: 2h 25m -> 2h 58m (+22.7%)
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.

Seems to be stuck building LLVM, probably because the caches being reset because this is an LLVM upgrade.

Let's keep this running so we can get as much stuff into cache as possible

  2. pr-check-2: 37m 31s -> 54m 44s (+45.9%)
  3. x86_64-rust-for-linux: 45m 48s -> 1h 3m (+37.8%)
  4. dist-aarch64-linux: 1h 50m -> 2h 28m (+35.2%)

  10. x86_64-gnu-nopt: 2h 25m -> 2h 58m (+22.7%)
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.
