Question

Puppet脚本可以判断它是否作为常规配置运行的一部分被调用，即Puppet代理定期应用配置（即puppet agent），或者是因为一次性操作（例如{{1 }，puppet agent -t）？

Answer 1

我在实践中还没有尝试过这个，但以下内容可能会有前进的方向：

command line上的设置（例如--test）也可用作Puppet master variables（例如$settings::test）。

Puppet主变量$servername标识puppet agent次运行的Puppet主变量，undef puppet apply运行$onetime = $settings::test or $settings::onetime or ($servername == undef)。

因此，整体解决方案的配方可能如下所示：

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.calculator);

    final SharedPreferences prefs = PreferenceManager
            .getDefaultSharedPreferences(this);

    editText3.setText(prefs.getString("autoSave", ""));
    editText4.setText(prefs.getString("autoSave1", ""));
    editText6.setText(prefs.getString("autoSave2", ""));
    editText8.setText(prefs.getString("autoSave3", ""));



    editText3.addTextChangedListener(new TextWatcher() {

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {

        }

        public void onTextChanged(CharSequence s, int start, int before,
                                  int count) {
            textViewResult.setText(addNumbers());
        }


        public void afterTextChanged(Editable s)
        {
            prefs.edit().putString("autoSave", s.toString()).commit();
        }


    });

    editText4.addTextChangedListener(new TextWatcher() {

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {

        }

        public void onTextChanged(CharSequence s, int start, int before,
                                  int count) {
            textViewResult.setText(addNumbers());

        }

        public void afterTextChanged(Editable s)
        {
            prefs.edit().putString("autoSave1", s.toString()).commit();
        }
    });

    editText6.addTextChangedListener(new TextWatcher() {

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {


        }

        public void onTextChanged(CharSequence s, int start, int before,
                                  int count) {
            textViewResult.setText(addNumbers());

        }

        public void afterTextChanged(Editable s)
        {
            prefs.edit().putString("autoSave2", s.toString()).commit();
        }
    });

    editText8.addTextChangedListener(new TextWatcher() {

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {


        }

        public void onTextChanged(CharSequence s, int start, int before,
                                  int count) {
            textViewResult.setText(addNumbers());

        }

        public void afterTextChanged(Editable s)
        {
            prefs.edit().putString("autoSave3", s.toString()).commit();
        }
    });
}

private String addNumbers() {
    int number1;
    int number2;
    int number3;
    int number4;
    if (editText3.getText().toString() != "" && editText3.getText().length() > 0) {
        number1 = Integer.parseInt(editText3.getText().toString());
    } else {
        number1 = 0;
    }
    if (editText4.getText().toString() != "" && editText4.getText().length() > 0) {
        number2 = Integer.parseInt(editText4.getText().toString());
    } else {
        number2 = 0;
    }
    if (editText6.getText().toString() != "" && editText6.getText().length() > 0) {
        number3 = Integer.parseInt(editText6.getText().toString());
    } else {
        number3 = 0;
    }
    if (editText8.getText().toString() != "" && editText8.getText().length() > 0) {
        number4 = Integer.parseInt(editText8.getText().toString());
    } else {
        number4 = 0;
    }

    int sum = (number1 * 2) + (number2 * 4) + (number3 * 2) + (number4 * 2);
    if (sum > 6) sum = 6;
    return sum + "";

} }
