Summary of changes

Add timeout knob for LibrariesInfoCache

Reason for change

On arm64 arch, tests may randomly fail with this error message:

 [2026-08-04 10:15:33.286 | error | PId: 103233 | TId: 103233] Failed to populate LibrariesInfoCache within timeout. Not registering custom iterate_phdr_function with libunwind.

The behavior is sound for a customer/production environment, but in CI, where we have less core and processing may take time. We should account for and make the time to wait longer.

Implementation details

  • Add a knob DD_INTERNAL_PROFILING_LIBRARIES_CACHE_START_TIMEOUT
  • Change Configuration.cpp to read and populate its value
  • Use it in LibrariesInfoCache

Test coverage

  • Add unit tests

Benchmarks

Benchmark execution time: 2026-08-05 10:43:31

Comparing candidate commit 0b22fab in PR branch gleocadie/flaky-due-to-libraries-info-cache-in-ci with baseline commit 915596f in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 0 performance regressions! Performance is the same for 72 metrics, 0 unstable metrics, 64 known flaky benchmarks, 62 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
