fix(tracer): resolve issue with not flushing during SIGTERM and SIGINT by brettlangdon · Pull Request #16342 · DataDog/dd-trace-py

brettlangdon · 2026-02-04T14:33:29Z

Description

Currently we do not properly register SIGTERM and SIGINT handlers for Tracer._atexit. This means any buffered traces or stats payloads may be lost during SIGTERM or SIGINT.

The impact on traces is up to 1 seconds worth of traces could be lost. For stats it is up to 10 seconds of stats which could be lost.

There are three changes here:

Properly registering the atexit.register_on_exit_signal for Tracer._atexit
Ensure our SIGTERM/SIGINT handlers restore and call the default Python behavior after our hooks have been called.
a. Or call whatever custom/user signals were registered before ours, defaulting to the default handlers if none were.
Change the order of the signal handlers being called
a. from first -> last, to last -> first so we can ensure the default signal handling behavior happens after all of our signals are called

Testing

Regression test added to ensure that all trace/stats writer configurations properly flush on exit.

We set a really high writer flush interval for traces to ensure we maintain the traces in the buffer while we trigger a SIGTERM/SIGINT.

I am having issues where some of the cases are failing but only in CI, and they are failing with weird messages "400: list index out of range", meaning something is maybe up with the test agent being able to properly read/resolve the snapshot data (best guess so far)

Seems like the NativeWriter takes much longer than the AgentWriter to startup, especially when stats is enabled, so we might not properly initialize the NativeWriter before we send the SIGTERM/SIGINT signal.

I added a small sleep, which I don't love, but makes the results more consistent it seems.
