This caused StartIngest to hang forever waiting for data from the pipe (never receiving EOF). The fix closes the pipe writer before returning early, which properly signals EOF to StartIngest and allows the test to complete. Fixes TestScan/respects_context_cancellation timeout on all platforms. --- internal/scan/repo/repo.go | 1 + 1 file changed, 1 insertion(+) diff --git a/internal/scan/repo/repo.go b/internal/scan/repo/repo.go index 692759f..8f7666d 100644 --- a/internal/scan/repo/repo.go +++ b/internal/scan/repo/repo.go @@ -149,6 +149,7 @@ func (s *Scanner) Scan(ctx context.Context, path string) (*model.ScanResult, err // to prevent resource leaks if context is already canceled. select { case <-ctx.Done(): + pw.Close() // Close pipe to unblock StartIngest errChan <- ctx.Err() return default: From 62bcd93a6f76287cb69b30cbce48fb9310127abb Mon Sep 17 00:00:00 2001 From: Yiftach Cohen Date: Sun, 18 Jan 2026 15:02:25 +0200 Subject: [PATCH 12/16] fix: add nolint directive for errcheck on pipe close The error from pw.Close() is intentionally not checked because: 1.
