Bumps CodSpeedHQ/action from 5.2.1 to 5.4.0.

Release notes

Sourced from CodSpeedHQ/action's releases.

v5.4.0

Bumps the CodSpeed runner to v5.4.0, including v5.3.0 and v5.3.1.

The Memory instrument now tracks physical (resident) memory and captures allocation call stacks to build memory flamegraphs. Both are enabled by default and can be turned off with the new disable-memory-track-physical and disable-memory-capture-stack inputs. Serialization is also faster on large memory benchmarks.

The action now exposes the id of the CodSpeed run as a run-id output, and CodSpeed now works on non-Ubuntu/Debian distributions such as Arch Linux.

🚀 Features

  • Track physical memory and capture allocation call stacks for memory flamegraphs, both enabled by default by @​not-matthias in #529, #522 and #553
  • Expose the run id as a GitHub Actions step output by @​moha-bekh in #551
  • Add an --experimental-disable-pythonmalloc-override flag (CODSPEED_EXPERIMENTAL_DISABLE_PYTHONMALLOC_OVERRIDE) to stop overriding the Python allocator, which can break free-threaded Python in simulation mode, by @​not-matthias in #539
  • Apply kernel memory tunables before memory-mode runs, and fail early when the kernel has no BTF by @​not-matthias in #507 and #524
  • Pause producers under ring buffer pressure in memory mode, and log process stops per reason by @​not-matthias in #543
  • Log which authentication method the run uses by @​fargito in #521

🐛 Bug Fixes

  • Support distributions CodSpeed publishes no valgrind package for (Arch, rolling releases) by @​moha-bekh in #525
  • Error out when the profile archive exceeds the upload size limit by @​lvaroqui in #557
  • Detect free-threaded Python from venv and uv before setting PYTHONMALLOC by @​not-matthias in #539
  • Honor deprecated experimental flags, including their falsey values, instead of ignoring them by @​not-matthias in #532 and #553
  • Fix memory tracking edge cases: reused pids, stack-ring overflow, BPF links held by forked processes, and allocator symbols aliased at an attached offset by @​not-matthias in #522 and #543
  • Attach memory tracking hooks without perf_event_open by @​GuillaumeLagrange in #536
  • Restore profiling sysctls in walltime mode by @​not-matthias in #507

⚠️ 7 benchmarks spent significant time in system calls

System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.

Measurement and system calls

ℹ️ 15 benchmarks have no flame graph

The flamegraph could not be generated because too much time was spent in runtime internals, making the visualization not useful for performance analysis.

⚠️ Different runtime environments detected

Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.

Open the report in CodSpeed to investigate

❌ 3 regressed benchmarks
✅ 185 untouched benchmarks
⏩ 77 skipped benchmarks1

Warning

Please fix the performance issues or acknowledge them on CodSpeed.
