fix(profiling): reinstall signal handler if needed #15415

KowalskiThomas · 2025-11-25T11:26:11Z

Description

https://datadoghq.atlassian.net/browse/PROF-13114

This PR makes sure the Python Profiler's signal handler (for SIGSEGV and SIGBUS) is properly installed when the Sampler thread starts.
Note that this (reinstalling our signal handler) does NOT break any other signal handler (Python's or another extension's) as our signal handler only swallows faults / jumps to the recovery path if it's been "armed" (otherwise it re-raises). What matters is that we should be the "first responder" when a fault happens.

This is an attempt to fix a crash we saw in the testing environment where some workloads receive segmentation faults clearly coming from safe_memcpy in FastAPI / Django apps.
The "real" root cause isn't yet known of me – Django and FastAPI don't seem to use PYTHONFAULTHANDLER or faulthandler based on the Github code – but after deploying those changes, we stopped seeing those crashes (0 in the past 3 days).

+    if (use_alternative_copy_memory()) {
+        std::call_once(segv_handler_once, init_segv_catcher);
+    }


call_once is far from free, but this is only called once at the start of the Sampling thread, so it's OK as far as I can tell.
