This fix restores and extends the username/email search functionality across workspace pages that was originally added in PR #14002. The issue was that:
1. The backend search functions for Models and Knowledge only searched `User.name` and `User.email`, but not `User.username`
2. The Functions admin page lacked user search entirely
Changes made:
Added User.username to backend search conditions for Models and Knowledge pages
Added complete user search (name, email, username) to the Functions admin page client-side filter
Remove Depends(get_session) from POST /query endpoint to prevent database connections from being held during embedding API calls (1-5+ seconds).
The Memories.get_memories_by_user_id() function manages its own short-lived session internally, releasing the connection before the slow EMBEDDING_FUNCTION() call begins.
Remove Depends(get_session) from POST /create endpoint to prevent database connections from being held during embedding API calls (1-5+ seconds).
The has_permission() and Knowledges.insert_new_knowledge() functions manage their own short-lived sessions internally, releasing connections before the slow embed_knowledge_base_metadata() call begins.
Remove Depends(get_session) from POST /{id}/update endpoint to prevent database connections from being held during embedding API calls (1-5+ seconds).
All database operations (get_knowledge_by_id, has_access, has_permission, update_knowledge_by_id, get_file_metadatas_by_id) manage their own short-lived sessions internally, releasing connections before and after the slow embed_knowledge_base_metadata() call.
Remove Depends(get_session) from the /v1/completions endpoint to prevent database connections from being held during the entire duration of LLM calls.
Previously, the database session was acquired at request start and held until the response completed. Under concurrent load, this exhausted the connection pool, causing QueuePool timeout errors.
The fix allows Models.get_model_by_id() and has_access() to manage their own short-lived sessions internally, releasing the connection immediately after authorization checks complete.
Remove Depends(get_session) from the /v1/chat/completions endpoint to prevent database connections from being held during the entire duration of LLM calls.
Previously, the database session was acquired at request start and held until the streaming response completed. Under concurrent load, this exhausted the connection pool, causing QueuePool timeout errors.
The fix allows Models.get_model_by_id() and has_access() to manage their own short-lived sessions internally, releasing the connection immediately after authorization checks complete.
