chore: bump CodSpeedHQ/action from 5.4.0 to 5.4.2

[dependabot]

Bumps CodSpeedHQ/action from 5.4.0 to 5.4.2.

Release notes

Sourced from CodSpeedHQ/action's releases.

v5.4.2

Bumps the CodSpeed runner to v5.4.2, including v5.4.1.

This release improves and adds support for memory flamegraphs in C++, Python and Node.js.

Fixes flamegraphs for Python in simulation mode in the exec CLI.

🚀 Features

• Name Python and Node.js frames in memory flamegraphs: emit their perf maps in memory mode, and harvest perf maps and JIT unwind data for memory tracking, by @​not-matthias in #556
• Launch node with the codspeed-node V8 flags for the current mode in codspeed exec, including through npm, npx and #!/usr/bin/env node scripts, by @​not-matthias in #556

🐛 Bug Fixes

• Always set PYTHONPERFSUPPORT, so Python codspeed exec targets keep their Python frames in simulation-mode flamegraphs, by @​not-matthias in #577
• Fix memory flamegraph stacks: restore return addresses hijacked by uretprobes in nested allocator calls, compare mapped modules against their mapping, and keep every placement of a module mapped more than once, by @​not-matthias in #564, #563 and #556
• Only pass --interpreted-frames-native-stack to node in analysis mode by @​not-matthias in #556
• Label dropped benchmarks in the comparison table by @​adriencaccia in #570

⚙️ Internals

• Pin memtrack 1.6.1 and exec-harness 1.4.1, through 1.4.0, by @​adriencaccia in #575 and #580

⚠️ 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.

Footnotes

1. 77 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (7d3af2c) during the generation of this report, so 624d39b was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
