Function CheckForUpdatesAsync

pkg/cli/update_check.go:247–276

CheckForUpdatesAsync performs update check in background (best effort) This is called from compile command and should never block or fail the compilation The context can be used to cancel the update check if the program is shutting down

(ctx context.Context, noCheckUpdate bool, verbose bool)

// This is called from compile command and should never block or fail the compilation
// The context can be used to cancel the update check if the program is shutting down
func CheckForUpdatesAsync(ctx context.Context, noCheckUpdate bool, verbose bool) {

	go func() {
		// Recover from any panics in the update check
		defer func() {
			if r := recover(); r != nil {
				updateCheckLog.Printf("Panic in update check (recovered): %v", r)
			}
		}()

		// Check if context was cancelled before starting
		if ctx.Err() != nil {
			updateCheckLog.Printf("Update check cancelled before starting: %v", ctx.Err())
			return
		}

		checkForUpdates(noCheckUpdate, verbose)
	}()

	// Give the goroutine a small window to complete quickly
	// This allows the message to appear before compilation starts
	// but doesn't block if the check takes longer
	select {
