chore(crashtracking): don't bail when no stack frames are received by gyuheon0h · Pull Request #1494 · DataDog/libdatadog

gyuheon0h · 2026-01-30T18:10:04Z

What does this PR do?

Fix handling of empty stacktraces in crash report receiver by treating zero frames as an incomplete stack and continuing rather than an error condition that bails

Motivation

When the crash collector sends BEGIN_STACKTRACE followed by END_STACKTRACE with no frames in between, this indicates that stack collection was attempted and completed, but no frames could be captured.
This can happen on:

musl-based Linux (Alpine) where stack unwinding may not be able to unwind past the signal handler
Node.js, where we have noticed that no frames are emitted but proceeds to send an END_STACKTRACE marker
Other edge cases where the unwinder fails to capture frames

Previously, the code would bail with an error when this happened. This would interfere with crash report sending.

Changes

The with_stack_set_complete method now initializes an empty complete stack (StackTrace::new_incomplete()) when no frames were received. This correctly represents the semantic meaning:

Frames received, collection finished: frames present, incomplete=false
No frames received, collection finished: empty, incomplete=true
Collection never completed, incomplete=true, streaming loop errors and report generation terminates and salvages whatever data it has received so far to send

How to test the change?

error[vulnerability]: Logging user input may result in poisoning logs with ANSI escape sequences

    ├ ID: RUSTSEC-2025-0055
    ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2025-0055
    ├ Previous versions of tracing-subscriber were vulnerable to ANSI escape sequence injection attacks. Untrusted user input containing ANSI escape sequences could be injected into terminal output when logged, potentially allowing attackers to:
      
      - Manipulate terminal title bars
      - Clear screens or modify terminal display
      - Potentially mislead users through terminal manipulation
      
      In isolation, impact is minimal, however security issues have been found in terminal emulators that enabled an attacker to use ANSI escape sequences via logs to exploit vulnerabilities in the terminal emulator.
      
      This was patched in [PR #3368](https://github.com/tokio-rs/tracing/pull/3368) to escape ANSI control characters from user input.
