From e141ba644b37041969fee61fb4f202249ccebf80 Mon Sep 17 00:00:00 2001 From: RohanExploit <178623867+RohanExploit@users.noreply.github.com> Date: Tue, 17 Feb 2026 14:08:52 +0000 Subject: [PATCH 1/4] feat(backend): optimize detection endpoints with image preprocessing Refactors `detect_traffic_sign_endpoint` and `detect_abandoned_vehicle_endpoint` to use `process_uploaded_image`. This adds validation (security), resizing (performance), and EXIF stripping (privacy) before sending images to the CLIP service. Reduces payload size significantly for high-resolution uploads and prevents processing of invalid files. --- .jules/bolt.md | 4 ++++ backend/routers/detection.py | 14 ++++---------- 2 files changed, 8 insertions(+), 10 deletions(-) diff --git a/.jules/bolt.md b/.jules/bolt.md index 6f687f0a..37ccd5b9 100644 --- a/.jules/bolt.md +++ b/.jules/bolt.md @@ -37,3 +37,7 @@ ## 2026-02-08 - Return Type Consistency in Utilities **Learning:** Inconsistent return types in shared utility functions (like `process_uploaded_image`) can cause runtime crashes across multiple modules, especially when some expect tuples and others expect single values.

This prevents the backend from starting. This fix broadens the exception handler to catch `Exception` during `import magic`, ensuring the app can start even without `libmagic` installed (falling back to PIL validation). --- backend/utils.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/backend/utils.py b/backend/utils.py index 2a0098c7..0e72eb72 100644 --- a/backend/utils.py +++ b/backend/utils.py @@ -21,7 +21,7 @@ try: import magic HAS_MAGIC = True -except ImportError: +except (ImportError, Exception): # Catch OSError (libmagic missing) and other startup errors HAS_MAGIC = False logger = logging.getLogger(__name__) From 1e5cc6a4dec912e8b268722e1bc9564415a64dbe Mon Sep 17 00:00:00 2001 From: RohanExploit <178623867+RohanExploit@users.noreply.github.com> Date: Tue, 17 Feb 2026 14:24:59 +0000 Subject: [PATCH 3/4] fix(backend): prevent startup crash on Gemini AI configuration Wraps `genai.configure()` in a try-except block to prevent the application from crashing at startup if `GEMINI_API_KEY` is invalid or missing.
