恢复自动代码文件 %s 失败: %w

Error message

恢复自动代码文件 %s 失败: %w

What it means

When rolling back a file that existed before the task, rollback rewrites the saved BeforeContent back via replaceAutoCodeFileAtomically. If that atomic restore fails, the error is wrapped with the target path so the developer knows which file could not be reverted. The underlying cause (temp file, chmod, rename failure) is the wrapped %w error.

Solutions

  1. Inspect the wrapped cause (%w) to see which step failed (mkdir / temp file / chmod / rename) and fix that specific condition
  2. Ensure the server process has write permission on the target's directory and the file itself
  3. Stop file watchers/editors holding locks on the path (especially on Windows) and retry
  4. Check disk space and mount status (read-only remount, ENOSPC) for the containing volume

Example fix

// before
$ ls -ld server/api/v1
dr-xr-xr-x  root root
// after
sudo chmod u+w server/api/v1  # or chown to the service user
Defensive patterns

Strategy: retry

Validate before calling

dir := filepath.Dir(targetPath)
if fi, err := os.Stat(dir); err != nil || !fi.IsDir() {
    return fmt.Errorf("restore dir invalid: %s", dir)
}
if err := unix.Access(dir, unix.W_OK); err != nil {
    return fmt.Errorf("not writable: %s", dir)
}

Try / catch

err := commitAutoCodeFileTask(task, publish, persist)
if err != nil && strings.Contains(err.Error(), "恢复自动代码文件") {
    // disk/watcher issue; after fixing the environment
    // restore from git and re-run
git checkout -- server/ web/
}

Prevention

When it happens

Trigger: replaceAutoCodeFileAtomically(file.TargetPath, file.BeforeContent, file.Mode) fails during rollback: target directory not writable, temp file creation/write failing, or os.Rename unable to replace the target (locked on Windows, cross-device, permission loss).

Common situations: Read-only or full disk, directory owned by another user, SELinux/AppArmor blocking writes, Windows file locking by an editor or watcher, or the target file's permissions were hardened after apply.
