ensureProxiedServerConfig: stat %s: %w

Error message

ensureProxiedServerConfig: stat %s: %w

What it means

After ensuring the parent directory exists, ensureProxiedServerConfig stats the config file itself to decide whether to reuse or generate it. Any stat error that is NOT 'file does not exist' is wrapped here. It surfaces unexpected filesystem failures when probing the config path — existence is handled separately, so this indicates real I/O trouble.

Solutions

  1. Read the wrapped errno: EACCES/EPERM → restore +x (traverse) permission on each ancestor directory (`chmod a+x <dir>`); EIO → check dmesg/disk health or remount the volume.
  2. If the path lives on a network/automounted filesystem, verify the mount is alive (`mount | grep <path>`, remount if stale).
  3. Check for symlink loops: `namei -l <path>` or `readlink -f <path>` and fix the broken link.
  4. Simplify or shorten the path if ENAMETOOLONG (deep nesting or very long HOME).
  5. Work around by supplying a custom config path on a healthy local filesystem.

Example fix

// before
$ ls -ld ~/.beads
d-w-------  ~/.beads        # no traverse bit, stat of children fails
// after
$ chmod u+x ~/.beads && bd serve
Defensive patterns

Strategy: validation

Validate before calling

if _, err := os.Stat(cfgPath); err != nil && !errors.Is(err, fs.ErrNotExist) {
	return fmt.Errorf("config path %s unusable: %w", cfgPath, err)
}

Type guard

func statProblem(path string) error {
	_, err := os.Stat(path)
	switch {
	case err == nil:
		return nil
	case errors.Is(err, fs.ErrNotExist):
		return nil // fine, will be created
	default:
		return err
	}
}

Try / catch

if _, err := os.Stat(cfgPath); err != nil && !errors.Is(err, fs.ErrNotExist) {
	switch {
	case errors.Is(err, fs.ErrPermission):
		// fix or prompt for permissions before proceeding
	default:
		log.Printf("config path not stat-able: %v", err)
	}
}

Prevention

When it happens

Trigger: os.Stat(path) returns an error other than fs.ErrNotExist: permission denied on a parent directory during lookup, path too long (ENAMETOOLONG), I/O error on a failing disk or network mount, invalid path characters, or a symlink loop.

Common situations: Unreadable parent directory (execute bit removed from ~/.beads or $HOME) so even existence checks fail; config path on a dead NFS mount; symlink loop after bad dotfile management; EIO on failing storage.
