写入自动代码 staging 失败: %w

Error message

写入自动代码 staging 失败: %w

What it means

Returned when writing the staged copy of the new file content via replaceAutoCodeFileAtomically fails. The staging directory was created under layout.root with os.MkdirTemp, so failures usually indicate disk-space exhaustion, staging-dir permission problems, or I/O errors. The original writeErr is wrapped with %w for errors.Is inspection.

Solutions

1. Free disk space on the volume holding the project root (check `df -h`); staged content plus existing files must fit.
2. Ensure nothing concurrently deletes the staging directory (exclude .autocode-staging-* from tmp cleaners/cron jobs).
3. Verify the server process has write permission on layout.root so MkdirTemp and staged writes succeed.
4. Retry after transient I/O failures; inspect the wrapped cause with errors.Is(err, syscall.ENOSPC) etc.

Example fix

// before: disk full
$ df -h /workspace  =>  100% used
// after
$ docker system prune  # or delete build artifacts
$ df -h /workspace  =>  40% used
# retry the autocode task

func canWriteStaging(root string) error {
  dir, err := os.MkdirTemp(root, ".autocode-staging-check-")
  if err != nil {
    return fmt.Errorf("cannot create staging dir under %s: %w", root, err)
  }
  probe := filepath.Join(dir, "probe")
  if err := os.WriteFile(probe, []byte("ok"), 0o666); err != nil {
    os.RemoveAll(dir)
    return fmt.Errorf("cannot write into staging dir: %w", err)
  }
  return os.RemoveAll(dir)
}

// Retry once after transient staging write failures, after freeing space
var err error
for i := 0; i < 2; i++ {
  err = svc.Create(c, req)
  if err == nil || !errors.Is(err, syscall.ENOSPC) {
    break
  }
  freeDiskSpaceOrAlert()
}
if err != nil {
  return err
}

When it happens

Trigger: Disk full (ENOSPC) when writing staged content; the staging directory was removed concurrently by a cleanup/tmp sweeper; write/permission error on the temp file; I/O error on the underlying volume.

Common situations: CI runners or containers with small ephemeral disks; tmpwatch/systemd-tmpfiles or manual cleanup deleting .autocode-staging-* directories mid-run; read-only root filesystems in hardened containers; quota limits on the repo volume.
