What does this PR do?

Adds a bin_test to check that crashtracker saguard correctly suppresses SIGCHLD and SIGPIPE

The test comment is pretty explanatory:

// Verifies that SIGCHLD and SIGPIPE handlers installed by the application are
// not invoked during crash handling (because SaGuard suppresses them), even
// though the crash handler spawns child processes (SIGCHLD) and writes to
// pipes (SIGPIPE).
//
// Expected operation:
// 1. setup() installs custom SIGCHLD and SIGPIPE handlers that write marker files when invoked
// 2. pre() verifies the handlers actually work as a baseline check
// 3. post() cleans up marker files and sets the output targets to "crash_sigchld" and
//    "crash_sigpipe" files.  If the SaGuard is working, the crash handler will suppress these
//    signals and the marker files will not be created

We cannot add determinism by explictly sending sigcld or sigpipe to the crashtracker process. Have no way of knowing if we are too early (when the crash handler has already started), or if we are too late (crash handler has already exited). This test at least will raise for sure if the crash handler ever fails to suppress SigChld or SigPipe.

Motivation

Good to have end to end tests

Benchmarks

Comparison

Benchmark execution time: 2026-03-24 18:05:16

Comparing candidate commit 177874b in PR branch gyuheon0h/PROF-14080-saguard-bin-test with baseline commit 7e7908c in branch gyuheon0h/PROF-14080-saguard-ct.

Found 0 performance improvements and 0 performance regressions! Performance is the same for 61 metrics, 0 unstable metrics.

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 ----------------------------------'
