From 84c6e1c5dd1a427c7f015e7461df59b889e66154 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 16 Mar 2026 09:19:55 +0000 Subject: [PATCH 1/4] perf: optimize dropbox token refresh by replacing blocking requests with httpx Replaced the synchronous `requests.post` calls in `app/api/dropbox.py` with asynchronous `httpx.AsyncClient().post` calls. This ensures that the FastAPI event loop is not blocked during network I/O, allowing better concurrent performance. Also updated the `test_api_dropbox.py` tests to use `httpx.AsyncClient.post` in mocks and properly construct `httpx.RequestError` in exception handling tests.
