What does this PR do?

This PR fixes a regression where SaGuard suppressed SIGCHLD with SIG_IGN, which can alter child reaping behavior (waitpid/ECHILD) and break sigchld_exec crash-test flows

Changes

  1. Add per-signal suppression modes in SaGuard
  2. Use split policy in crash handling
  3. Loosen up restirctions in child cleanup in ProcessHandle::finish
  4. serialize signal-global unit tests to avoid race condition modifying global state for saguard unit tests

Motivation

Context: We were originally not blocking any signals. In fix(crashtracking): guard sigchld and sigpipe during crashtracker signal handler execution, we started blocking sigchld and sigpipe. However, blocking sigchld causes deadlocks for the following test

test(crashtracking): skip sigchld_exec test on CentOS 7 deadlock

This change works because it prevents interference with the application's expected signal handling while still protecting the crash handler from re-entrant signals

Additional Notes

How to test the change?

cargo nextest run -p libdd-crashtracker --lib -- collector::saguard::single_threaded_tests
cargo nextest run -p bin_tests test_crash_tracking_bin_sigchld_exec

Comparison

Benchmark execution time: 2026-03-26 15:58:08

Comparing candidate commit d8a06b8 in PR branch gyuheon0h/fix-sigchld-deadlock with baseline commit e8f9d68 in branch main.

Found 1 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 ----------------------------------'
