The optional `file:__file__` directive installs an overlay configuration file `__file__`. Multiple commands must be comma (`,`) or semicolon (`;`) separated. If the directives conflict, the last one is used. + The service plugin supports configuration overlays only for systemd. In other init systems, this directive is ignored. The configuration overlay files are copied to `/etc/systemd/system/__service_name__.service.d/` directories. Upon profile unloading, the directory is removed if it is empty. + With systemd, the `start` command is implemented by `restart` in order to allow loading of the service configuration file overlay. + NOTE: With non-systemd init systems, the plug-in operates on the current runlevel only. + .Start and enable the `sendmail` service with an overlay file ==== ---- [service] service.sendmail=start,enable,file:${i:PROFILE_DIR}/tuned-sendmail.conf ---- The internal variable `${i:PROFILE_DIR}` points to the directory from which the profile is loaded. ==== c s& t t| �j||� d| _| j� | _d S )NT)�superrL r Z_has_dynamic_options�_detect_init_system� _init_handler)r �args�kwargs)� __class__r r r � s zServicePlugin.__init__c C s t j|dgd�\}}|dkS )Nr )r& )r r )r Zcommandr r r r r � _check_cmd� s zServicePlugin._check_cmdc C s� | j ddg�r tjd� t� S | j dg�r:tjd� t� S | j ddg�rXtjd� t� S | j d dg�rvtjd � t� S tjd ��d S ) Nr: r% zdetected systemdr* zdetected generic sysvinitz update-rc.dz-hzdetected sysv-rcz rc-updatezdetected openrcz8Unable to detect your init system, disabling the plugin.) rS r; �debugr8 r) r/ r0 � exceptionsZNotSupportedPluginException)r r r r rN � s z!ServicePlugin._detect_init_systemc C s� t jd|�}t� }x~|D ]v}|dkr,d|_q|dkr<d|_q|dkrLd|_q|dkr\d|_q|d d� d kr||dd � |_qtjd ||f � qW |S ) Nz \s*[,;]\s*r Tr$ Fr r" � zfile:z*service '%s': invalid service option: '%s')r5 r r r r r r; r@ )r r �val�lr! �ir r r �_parse_service_options� s z$ServicePlugin._parse_service_optionsc s6 d|_ d|_tj� fdd�|jj� D ��� _i |_d S )NFTc sT g | ]L\}}|d d� dkrt |�dkr|dd � � j|dd � � jj|��f�qS )N� zservice.)�lenrZ Z _variables�expand)�.0Zoption�value)r r r � <listcomp> s z0ServicePlugin._instance_init.<locals>.<listcomp>)Z_has_dynamic_tuningZ_has_static_tuning� collections� OrderedDictZoptions�items� _services�_services_original)r �instancer )r r �_instance_init s z ServicePlugin._instance_initc C s d S )Nr )r rf r r r �_instance_cleanup s z ServicePlugin._instance_cleanupc C sT |r| j j|� n|d k r&| j j|� |r:| j j||� n|d k rP| j j||� d S )N)rO r r" r r$ )r r r r r r r r �_process_service s z ServicePlugin._process_servicec C s� | j j� }|d kr tjd� d S x�| jj� D ]�}| j j|d |�}| j j|d �}t|||d j |�|j |d < |d j r�| j j |d |d j � | j |d |d j |d j|� q,W d S )NzCannot detect runlevelr r )rO r r; r@ rd rc r( r' r r re r ri r r )r rf r r! r( r' r r r �_instance_apply_static s z$ServicePlugin._instance_apply_staticc C sH | j j� }|d kr&tjtjd � dS d}�x| jj� D �]}| j j|d |d j �}|r~tj tj d |d |d j f � nR|d k r�tjtjd |d |d j f � d}n"tj tj d |d |d j f � | j j |d |�}| j j|d �} | jd |d |d j| |�dk�rd}| jd |d |d j||�dkr8d}q8W |S ) Nzcannot detect runlevelFTr r z'service '%s' configuration '%s' matchesz'service '%s' configuration '%s' differsz service '%s' configuration '%s'z %s runningz %s enabled)rO r r; r@ rA ZSTR_VERIFY_PROFILE_FAILrd rc r r r< ZSTR_VERIFY_PROFILE_OKZ STR_VERIFY_PROFILE_VALUE_MISSINGr( r' Z _verify_valuer r ) r rf Zignore_missingZdevicesr �retr!
