o ;j� � @ s^ d Z ddlZddlZddlZddlZe�e�ZdZdd� Z d dd �Z dd d �Z dS )a| Loop state Allows for looping over execution modules. .. versionadded:: 2017.7.0 In both examples below, the execution module function ``boto_elb.get_instance_health`` returns a list of dicts. The condition checks the ``state``-key of the first dict in the returned list and compares its value to the string `InService`. .. code-block:: yaml wait_for_service_to_be_healthy: loop.until: - name: boto_elb.get_instance_health - condition: m_ret[0]['state'] == 'InService' - period: 5 - timeout: 20 - m_args: - {{ elb }} - m_kwargs: keyid: {{ access_key }} key: {{ secret_key }} instances: "{{ instance }}" .. warning:: This state allows arbitrary python code to be executed through the condition parameter which is literally evaluated within the state. Please use caution. .. versionchanged:: 3000 A version that does not use eval is now available. It uses either the python ``operator`` to compare the result of the function called in ``name``, which can be one of the following: lt, le, eq (default), ne, ge, gt. Alternatively, `compare_operator` can be filled with a function from an execution module in ``__salt__`` or ``__utils__`` like the example below. The function :py:func:`data.subdict_match <salt.utils.data.subdict_match>` checks if the ``expected`` expression matches the data returned by calling the ``name`` function (with passed ``args`` and ``kwargs``). .. code-block:: yaml Wait for service to be healthy: loop.until_no_eval: - name: boto_elb.get_instance_health - expected: '0:state:InService' - compare_operator: data.subdict_match - period: 5 - timeout: 20 - args: - {{ elb }} - kwargs: keyid: {{ access_key }} key: {{ secret_key }} instances: "{{ instance }}" � NZloopc C s dS )NT� r r r �D/opt/saltstack/salt/lib/python3.10/site-packages/salt/states/loop.py� __virtual__H s r � �< c C s< | i ddd�}|du r d}|du ri }| t vr d| � �|d< |S |du r*d|d< |S t|ttf�s7d |d< |S t|ttf�sDd |d< |S td rVd | � d �|d< d|d< |S |du r\g }|du rbi }t�� | }t�� |k r�t | |i |��}t|�r�d|d< d|� d�|d< |S t�|� t�� |k snd�|�|d< |S )aS Loop over an execution module until a condition is met. :param str name: The name of the execution module :param list m_args: The execution module's positional arguments :param dict m_kwargs: The execution module's keyword arguments :param str condition: The condition which must be met for the loop to break.
