创建自动代码 staging 目录失败: %w

Error message

创建自动代码 staging 目录失败: %w

What it means

Thrown by prepareAutoCodeFileTask when os.MkdirTemp(layout.root, autoCodeStagingPrefix) cannot create the temporary staging directory under the auto-code root. All generated files are written here first, so the task cannot proceed without it.

Solutions

1. Check the wrapped %w cause (permission denied / no such file / no space) and fix accordingly.
2. Ensure the auto-code root exists and is writable by the server process user (chown/chmod).
3. Free disk space or raise quota if 'no space left on device'.
4. In containers, mount the code root as a writable volume.

if fi, err := os.Stat(root); err != nil || !fi.IsDir() {
    return fmt.Errorf("root not writable/missing: %s", root)
}
if err := syscall.Access(root, os.O_WRONLY); err != nil {
    return fmt.Errorf("root not writable: %w", err)
}

task, err := prepareAutoCodeFileTask(layout, files)
if err != nil {
    if errors.Is(err, os.ErrPermission) {
        return fmt.Errorf("run server with write access to %s", layout.root)
    }
    return err
}
defer os.RemoveAll(task.stagingDir)

When it happens

Trigger: Called via prepareRequestFileTask/Create when creating the temp dir fails: root directory missing or read-only, disk full, permission denied for the process user, or too many open files.

Common situations: Running the server as a non-root user without write access to the repo root; read-only container filesystem; disk quota exceeded; root deleted after startup.
