Each command is either a list or string. Perform the following: - If the command is a list, pop the first element if it is None - If the command is a list, insert base_command as the first element if not present. - When the command is a string not starting with 'base-command', warn. Allow flexibility to provide non-base-command environment/config setup if needed. @commands: List of commands.

[cmd, arg1, arg2...] :param data: input to the command, made available on its stdin. :param rcs: a list of allowed return codes. If subprocess exits with a value not in this list, a ProcessExecutionError will be raised. By default, data is returned as a string. See 'decode' parameter. :param capture: boolean indicating if output should be captured. If True, then stderr and stdout will be returned. If False, they will not be redirected. :param shell: boolean indicating if this should be run with a shell. :param logstring: the command will be logged to DEBUG. If it contains info that should not be logged, then logstring will be logged instead. :param decode: if False, no decoding will be done and returned stdout and stderr will be bytes. Other allowed values are 'strict', 'ignore', and 'replace'. These values are passed through to bytes().decode() as the 'errors' parameter. There is no support for decoding to other than utf-8. :param update_env: update the environment for this command with this dictionary. this will not affect the current processes os.environ. :param cwd: change the working directory to cwd before executing the command. :param timeout: maximum time for the subprocess to run, passed directly to the timeout parameter of Popen.communicate() :return if not capturing, return is (None, None) if capturing, stdout and stderr are returned. if decode: entries in tuple will be string if not decode: entries in tuple will be bytes Nr zFRunning command %s with allowed return codes %s (shell=%s, capture=%s)�utf-8c S s$ g | ] }t |t�r|n|�d ��qS )rH )r r0 r= )�.0�xr r r � <listcomp> s zsubp.<locals>.<listcomp>z Running {})r r �stdin�envrC rF )rG r � -)r" r$ r( r r c s t | t�r| �|� �S | S �Nr/ )r@ �m�r1 r r �ldecode s zsubp.<locals>.ldecode)r r r# r" )rH )�os�environ�copy�updater �debug� subprocess�PIPEZDEVNULLr r0 r= r r? r ZTimedr �PopenZ communicate�OSErrorr r( � returncoder )r< r@ rA rB rC rD r1 rE rF rG rM r r rL Z bytes_args�sp�out�err�erR �rcr rQ r �subp� s� 2 � ��� 6 �� �rb c C s� | dv rd} n<t | t�s(td| � ���n"tj�| �} | �d�rJ| dd � } |sR| S t|�rt|d dkrt|dd � }qRtj�| |�S )N)N� �/z Unexpected input for target: z//r r ) r r � ValueErrorrS �path�abspathr �lenr )�targetrf r r r � target_path) s rj )r4 c C s� t |�}tjj| v r&tt || ��r&| S |d u rhdd� tj�dd��tj�D �}|dkrZ|n dd� |D �}dd� |D �}|D ],}tjj� || f�}tt ||��rz| S qzd S )Nc S s g | ]}|� d ��qS )�")�strip�rI �pr r r rK H s zwhich.<locals>.<listcomp>�PATHrc rd c S s g | ]}|� d �r|�qS )rd )r rm r r r rK L � c S s g | ]}t j�|��qS r )rS rf rg rm r r r rK O rp ) rj rS rf �sep�is_exerT �get�split�pathsepr )Zprogram�searchri �pathsrf Zppathr r r �which> s �� rx c C s t j�| �ot �| t j�S rO )rS rf �isfile�access�X_OK)Zfpathr r r rr Y s rr c C s> |rt j�| �sd S g }g }|d u r*g }n.t|t�r@t|�g}nt|t�rP|}ntd��tt �| ��D ]�}t j� | |�}t |�r�|� |� zt ||g dd� W n8 t y� } z t�|� |� |� W Y d }~n d }~0 0 qft j�|�r�t�d|� qft�d|� qf|�r:|�r:tdt|�� dd� |�� d t|�� d ���d S ) Nz%exe_prefix must be None, str, or listF)rB zjskipping %s as its not executable or the underlying file system is mounted without executable permissions.z Not executing special file [%s]z Runparts: z failures (�,z) in z attempted commands)rS rf �isdirr r r r �sorted�listdirr rr r rb r r rW ry r � RuntimeErrorrh ) ZdirpZ skip_no_existZ exe_prefixZfailedZ attempted�prefixZexe_nameZexe_pathr` r r r �runparts^ s@ " � ��r� )NN)NN)TN) �__doc__� collectionsZloggingrS rX r( r �ior �typingr r r Z cloudinitr Z getLoggerr9 r � namedtupler r r+ r r r0 r? rb rj rx rr r� r r r r �<module> s> 3N � �
