chore(profiling): move echion to dd-trace-py #15136

What does this PR do?

https://datadoghq.atlassian.net/browse/PROF-12683

This PR moves the source code of Echion from the Echion repository (https://github.com/P403n1x87/echion) to dd-trace-py. We hope that doing this will lead to an improved developer experience in dd-trace-py, as we will effectively:

Reduce the number of touch points required when we make a change to the Python sampler
Eliminate the need for "round-trips" between Echion and dd-trace-py (when the dd-trace-py CI captures an issue that the Echion CI missed)
Make it easier to iterate locally in dd-trace-py (currently, re-building Stack V2 with an updated version of Echion requires nuking the build/ directory / cache, meaning we need to build everything from scratch, which takes time)

Note The version of the code that is in this PR is not the latest version of Echion (missing a few PRs). I am still sending the PR for review (so that I can get an approval on the form and general idea) and I will make sure to include/backport any changes merged to Echion before I merge this PR to dd-trace-py.

Note I have copied .clang-format over as to minimise the size of the diff and make it easier to port changes from Echion while the PR is in review. I will remove the custom .clang-format and use the default one from dd-trace-py in a later PR.

Estimated cost is $60.92 for chore(profiling): move echion to dd-trace-py (cumulated CI duration: -494202h1m28.528371712s)

Can you make it explicit from which commit hash this is copied?

KowalskiThomas · 2025-11-18T09:23:59Z

@taegyunkim Can you make it explicit from which commit hash this is copied?

Yes absolutely. What I planned on doing (once I'd get the required approvals) is:

Update the commits in the history to include references to the original commits in Echion
Update the PR description to explain what each commit maps to (since I need to backport some things from Echion)

ddtrace/internal/datadog/profiling/stack_v2/echion/echion/mojo.h

vlad-scherbich · 2025-11-18T16:11:20Z

@KowalskiThomas Is this PR mostly copy-paste from the echion repo? Are there specific parts we should focus on to review, as the PR is over 4K lines.

KowalskiThomas · 2025-11-18T16:41:14Z

Note Since #15311 is not purely copying C++ code, I will wait until it is merged before porting anything relevant from it to this PR, then merge the current PR!

Also I still can't merge for the time being as I need an approval from apm-core-python.

emmettbutler

Note that in the long run we actually hope to separate the profiling code entirely into its own repo. I can see this change as a step along that path.
