error deleting window: %w

Error message

error deleting window: %w

What it means

CloseWindow removes the Window row via wstore.DBDelete after (attempting to) delete its workspace; this error wraps the delete failure. Note CloseWindow tolerates a missing window (it just logs) but returns this error if the row exists yet cannot be deleted.

Solutions

1. Inspect the wrapped %w error for the delete root cause
2. Check for other waveterm processes locking the DB and stop them
3. Verify disk space and state-directory permissions
4. Run CheckAndFixWindow on next startup to reconcile orphaned windows

Example fix

// before
err = wstore.DBDelete(ctx, waveobj.OType_Window, windowId)
if err != nil {
	return fmt.Errorf("error deleting window: %w", err)
}
// after
if err := wstore.DBDelete(ctx, waveobj.OType_Window, windowId); err != nil {
	return fmt.Errorf("error deleting window %s: %w", windowId, err)
}

if _, err := wcore.GetWindow(ctx, windowId); err != nil {
	return nil // window already gone; nothing to close
}

err := wcore.CloseWindow(ctx, windowId, false)
if err != nil && strings.Contains(err.Error(), "error deleting window") {
	log.Printf("window row could not be deleted, will retry: %v", err)
	// retry once after checking DB availability
}

When it happens

Trigger: wcore.CloseWindow(ctx, windowId, fromElectron) where the window exists (GetWindow succeeded) but DBDelete(ctx, OType_Window, windowId) fails — DB write error, constraint, or corruption.

Common situations: DB locked by a concurrent waveterm process; disk full during delete; corrupted DB index preventing row removal; foreign-object cleanup partially failing leaving inconsistent state.
