Host paths must be absolute (initial '/'), and sos_* directory paths must be a path relative to the root of the archive. :param mode: An optional mode to be used when creating path components. :returns: A rewritten destination path in the case that one or more symbolic links in intermediate components of the path have altered the path destination. zMaking leading paths for c s | j tjj� d��S )z>Test whether path ``path`` is inside the archive. r< )rR r? r+ rF )r+ )�rootr r � in_archive� s z8FileCacheArchive._make_leading_paths.<locals>.in_archiver= r r< z Making path )r% zMaking symlink 'z' -> 'r> zMaking directory )r= r< )r rG rR r? r+ �isdirrS �split�append�reverserF �exists�islink�readlink�_make_leading_paths�normpathrM rA �symlink�mkdir)r r r% r rV �src_dirr+ Z path_comps�head�tailZabs_pathZsrc_path�comp�targetZ target_dirZ target_srcr )rU r r^ � sL z$FileCacheArchive._make_leading_pathsFc C sd |p | j |�}|tkr |}ntjj|�d }|s4|S tjj|�r^tjj|� r^td|� d���tjj|�s�|tkrv|ntjj|�d }| j|� dd� }|r�|S tjj|��r`tj |�}d} |t kr�t j |j � r�t| |df ��|tko�t j|j � �r t| |df ��|tk�r2||j � �r2t| |d f ��|tk�r\t j|j � �r\t| |d f ��d S |S ) a4 Check a new destination path in the archive. Since it is possible for multiple plugins to collect the same paths, and since plugins can now run concurrently, it is possible for two threads to race in archive methods: historically the archive class only needed to test for the actual presence of a path, since it was impossible for another `Archive` client to enter the class while another method invocation was being dispatched. Deal with this by implementing a locking scheme for operations that modify the path structure of the archive, and by testing explicitly for conflicts with any existing content at the specified destination path. It is not an error to attempt to create a path that already exists in the archive so long as the type of the object to be added matches the type of object already found at the path. It is an error to attempt to re-create an existing path with a different path type (for example, creating a symbolic link at a path already occupied by a regular file). :param src: the source path to be copied to the archive :param path_type: the type of object to be copied :param dest: an optional destination path :param force: force file creation even if the path exists :returns: An absolute destination path if the path should be copied now or `None` otherwise r zpath 'z ' exists and is not a directoryc S s( t tj| �tj| �tj| �tj| �g�S )N)�any�stat�S_ISBLK�S_ISCHR�S_ISFIFO�S_ISSOCK)r% r r r � is_special8 s z/FileCacheArchive.check_path.<locals>.is_specialz path '%s' exists and is not a %sz regular filez symbolic linkz special fileZ directoryN)rP �P_DIRr? r+ rX r[ rW � ValueErrorr^ �lstat�P_FILErh �S_ISREG�st_mode�P_LINK�S_ISLNK�P_NODE�S_ISDIR) r r � path_typer r! �dest_dirrb rm �stZve_msgr r r � check_path s6 zFileCacheArchive.check_pathc C s� ydt j|�}|jd�s |jd�rDtj||� t j||j|jfd� n tj||� t j ||j |j � W n: t k r� } z | j d|� d|� d�� W Y d d }~X nX d S )Nz/sys/z/proc/)�nszcaught 'z' setting attributes of 'r> )r? rh rR �shutilZcopymode�utime� st_atime_ns� st_mtime_nsZcopystat�chown�st_uid�st_gid� Exceptionr )r r r �_stat�er r r �_copy_attributesT s z!FileCacheArchive._copy_attributesc C s | j �� |s|}| j|t|d�}|s*d S t|dd �s�ytj||� W nP tk r� } z4|jd�s�|jd�rnn| jd|� d|� d�� W Y d d }~X nX | j ||� d|� d�}n@|j d� t |d d d �� }x|D ]}|j |� q�W W d Q R X d }| j d |� d| j� d�� W d Q R X d S )N)r! �readz/sys/z/proc/zFile z not collected: 'r> r r# zutf-8)�encodingz open filezadded z to FileCacheArchive ')r: r{ rq �getattrr} �copy�OSErrorrR r r� �seek�open�writer rG )r r r r! r� � file_name�f�liner r r r" a s* * zFileCacheArchive.add_filer# c C s� | j �� |}| j|tdd�}tj||dd��X}t|t�rD|jdd�}|j|� t j j |�rf| j ||� | j d|� d| j� d �� W d Q R X W d Q R X d S ) NT)r! zutf-8)r� �utf8�ignorezadded string at 'z' to FileCacheArchive 'r> )r: r{ rq �codecsr� � isinstance�bytes�decoder� r? r+ r[ r� r rG )r r$ r r% r r� r r r r& � s zFileCacheArchive.add_stringc C sj | j �Z | j|t�}|s d S tj|dd d��}|j|� W d Q R X | jd|� d| j� d�� W d Q R X d S )N�wb)r� zadded binary content at 'z' to archive 'r> )r: r{ rq r� r� r� r rG )r r$ r r� r r r r' � s zFileCacheArchive.add_binaryc C s� | j d|� d|� d�� | j�R | j|t�}|s4d S tjj|�sltj||� | j d|� d|� d| j� d�� W d Q R X | j d|� d|� d |� �� tjj |�}tjj tjj ||��}| j |�}d d � }tjj |��s�tjj|��rb|}tjj |�}tjj |tj|��}tjj||�}|||��r<| j d |� d |� d�� d S | j d|� d|� d�� | j||� nntjj|��r�| j d|� d�� | j|� nBtjj|��r�| j d|� d�� | j|� n| j d|� d|� �� d S )Nzadding symlink at 'z' -> 'r> zadded symlink at 'z' to 'z' in archive 'zLink follow up: source=z link_name=z dest=c S s� t jj| �}t jj|�s.t jjt jj||��}t jj| �} | |krFdS yt j| � W n2 tk r� } z|jdkrtdS � W Y dd}~X nX dS )z�Return ``True`` if the symbolic link ``link_name`` is part of a file system loop, or ``False`` otherwise.
