This is necessary on minions with older releases of the ``rar`` CLI tool, which do not support listing the contents in a parsable format. .. _rarfile: https://pypi.python.org/pypi/rarfile List the files and directories in an tar, zip, or rar archive. .. note:: This function will only provide results for XZ-compressed archives if the xz_ CLI command is available, as Python does not at this time natively support XZ compression in its tarfile_ module. Keep in mind however that most Linux distros ship with xz_ already installed. To check if a given minion has xz_, the following Salt command can be run: .. code-block:: bash salt minion_id cmd.which xz If ``None`` is returned, then xz_ is not present and must be installed. It is widely available and should be packaged as either ``xz`` or ``xz-utils``. name Path/URL of archive archive_format Specify the format of the archive (``tar``, ``zip``, or ``rar``). If this argument is omitted, the archive format will be guessed based on the value of the ``name`` parameter. options **For tar archives only.** This function will, by default, try to use the tarfile_ module from the Python standard library to get a list of files/directories. If this method fails, then it will fall back to using the shell to decompress the archive to stdout and pipe the results to ``tar -tf -`` to produce a list of filenames. XZ-compressed archives are already supported automatically, but in the event that the tar archive uses a different sort of compression not supported natively by tarfile_, this option can be used to specify a command that will decompress the archive to stdout. For example: .. code-block:: bash salt minion_id archive.list /path/to/foo.tar.gz options='gzip --decompress --stdout' .. note:: It is not necessary to manually specify options for gzip'ed archives, as gzip compression is natively supported by tarfile_. strip_components This argument specifies a number of top-level directories to strip from the results. This is similar to the paths that would be extracted if ``--strip-components`` (or ``--strip``) were used when extracting tar archives. .. versionadded:: 2016.11.2 clean : False Set this value to ``True`` to delete the path referred to by ``name`` once the contents have been listed. This option should be used with care. .. note:: If there is an error listing the archive's contents, the cached file will not be removed, to allow for troubleshooting. verbose : False If ``False``, this function will return a list of files/dirs in the archive. If ``True``, it will return a dictionary categorizing the paths into separate keys containing the directory names, file names, and also directories/files present in the top level of the archive. .. versionchanged:: 2016.11.2 This option now includes symlinks in their own list. Before, they were included with files. saltenv : base Specifies the fileserver environment from which to retrieve ``archive``. This is only applicable when ``archive`` is a file from the ``salt://`` fileserver. source_hash If ``name`` is an http(s)/ftp URL and the file exists in the minion's file cache, this option can be passed to keep the minion from re-downloading the archive if the cached copy matches the specified hash. .. versionadded:: 2018.3.0 use_etag If ``True``, remote http/https file sources will attempt to use the ETag header to determine if the remote file needs to be downloaded. This provides a lightweight mechanism for promptly refreshing files changed on a web server without requiring a full hash comparison via the ``source_hash`` parameter. .. versionadded:: 3005 .. _tarfile: https://docs.python.org/2/library/tarfile.html .. _xz: http://tukaani.org/xz/ CLI Examples: .. code-block:: bash salt '*' archive.list /path/to/myfile.tar.gz salt '*' archive.list /path/to/myfile.tar.gz strip_components=1 salt '*' archive.list salt://foo.tar.gz salt '*' archive.list https://domain.tld/myfile.zip salt '*' archive.list https://domain.tld/myfile.zip source_hash=f1d2d2f924e986ac86fdf7b36c94bcdf32beec15 salt '*' archive.list ftp://10.1.2.3/foo.rar """ def _list_tar(name, cached, decompress_cmd, failhard=False): """ List the contents of a tar archive.
