refactor(profiling): use two-time upload api in libdatadog by KowalskiThomas · Pull Request #16467 · DataDog/dd-trace-py

KowalskiThomas · 2026-02-12T11:17:02Z

What does this PR do?

This PR changes the Profiler codebase to use the new two-time upload API (1. create the tokio runtime; 2. actually start the upload) to avoid a race condition often reported by TSan the profiling_native job -- see DataDog/libdatadog#1733. pr

The problem was that in some cases, we could have a thread trying to use a cancellation token to cancel an ongoing upload before the associated tokio runtime had finished initialising, leading to that race condition.
This same race condition was also responsible for some crashes reported by Crash Tracking.

Note this PR currently points to a specific commit SHA in libdatadog -- before merging it we'll have to update that SHA and upgrade libdatadog in dd-trace-py to be able to use that new API.

## What does this PR do? This PR splits the Exporter creation process into two steps (two functions to call): 1. Create the Tokio runtime with `init_runtime` 2. Upload the Profile with `send_blocking` (`send_blocking` calls `init_runtime` if it hasn't been initialised from the outside) This fixes a TSan-detected race condition where we try to cancel the Upload request (using the Cancellation Token) at the same time the runtime is being initialised. Example runtime Profiler fix PR: DataDog/dd-trace-py#16467 The PR also updates the existing `exporter.cpp` example to use the new function (tested with `cargo ffi-test --filter exporter`). ## Open questions Currently, the PR maintains compatibility with existing usages -- not explicitly calling `init_runtime` will make `send_blocking` call it when it needs it. However, this is risky (for the reasons that made us make this PR in the first place). * Should we prevent people from doing this? _Doing so will break compatibility with current usages._ * ... Or should we instead keep the race? _Doing so will guarantee backwards compatibility but also not force usages to be fixed._ --- We ended up going for the second, keeping the race so that we don't have a breaking API change.
