chore: update bytecode support for python 3.14 #14668

emmettbutler · 2025-09-22T17:37:46Z

This change updates the ddtrace code that directly edits or depends on specific bytecode instructions to work with Python 3.14. New tests exercising this code under 3.14 will be added in a forthcoming change. Validation for this change is the fact that existing tests still pass.

Pulled from the 3.14 integration branch #14264

Should we add a short note in the changelog for this? I know it could be useful for future me to know when we started supporting 3.14 without needing to check the git history

@tylfin I'm planning on adding a release note on the PR that includes tests against 3.14. This pull request alone isn't enough to fully support 3.14 - see #14264 for that.
