From aa109cc1b6596ccb7e47503e5be3d0be7c91c0ea Mon Sep 17 00:00:00 2001 From: colombod Date: Tue, 1 Sep 2026 08:53:17 +0000 Subject: [PATCH 1/2] chore(deps): migrate to uvicorn-worker, silence deprecation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added uvicorn-worker>=0.4.0 to pyproject.toml (uvicorn 0.41.0 and gunicorn 25.1.0 unchanged in uv.lock). Swapped gunicorn worker_class from uvicorn.workers.UvicornWorker to uvicorn_worker.UvicornWorker. Updated test references and stale worker import paths in codebase. No behavior change — dependency add + internal reference swap only. 🤖 Generated with Amplifier Co-Authored-By: Amplifier <240397093+microsoft-amplifier@users.noreply.github.com> --- AGENTS.md | 1 + context_intelligence_server/logging_config.py | 21 +++++-------------- context_intelligence_server/main.py | 2 +- pyproject.toml | 1 + tests/test_logging_config.py | 2 +- tests/test_run_entrypoint.py | 2 +- uv.lock | 15 +++++++++++++ 7 files changed, 25 insertions(+), 19 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index a6edbc3c..7a152f2e 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -444,5 +444,6 @@ with admin").
