chore(tornado): v4.0 deprecations [backport 3.19] #15303

dd-octo-sts · 2025-11-17T17:15:24Z

Backport 75a19c2 from #15274 to 3.19.

Description

Deprecated Tornado versions older than v6.1 and programmatic configuration via ddtrace.contrib.tornado. Users should upgrade to Tornado v6.1+ and use environment variables with import ddtrace.auto.

Motivation

Tornado v6.1 (released in 2020) added contextvars support, eliminating the need for a custom Tornado Context Provider. This allows us to remove the last integration specific Context Provider and simplify our context API.
