PR 3136, filed by Roshan931 and closed against issue 3047, tackles a frustrating first-run bug. When developers ran the setup environment command in Docker, it would fail. The root cause: the backend startup process spawns Supabase, and its output was being piped but never read. On a first run, Supabase pulls Docker…
The fix introduces a helper function, exported as "wait for backend start," that continuously drains standard output and standard error as the process runs, instead of letting them pile up unread. This is a classic pipe-buffer deadlock, the kind of bug that only shows up under real-world conditions, like a slow…
