chore(tornado): v4.0 deprecations #15274

mabdinur · 2025-11-14T16:13:59Z

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.

I think you are moving too quick here with some of the removals, this should be deprecation warnings only for tornado version support and public API deprecation only.

removals should come later.

I don't think this makes sense as a 4.0 backport. It looks to me like this diff is mostly about deprecating rather than removing, which is appropriate for 3.19.

dd-gitlab/microbenchmarks: [appsec_iast_aspects_split]

I just want the same set of changes in both 3.19 and 4.0 branches. Then in 4.0 we can do the removals in a follow up PR. That way we keep the commit histories consistent across branches and reduce the likelihood of merge conflicts.
