It is a renewed alternative implementation for Python's original :py:func:`platform.linux_distribution` function, but it provides much more functionality. An alternative implementation became necessary because Python 3.5 deprecated this function, and Python 3.7 is expected to remove it altogether. Its predecessor function :py:func:`platform.dist` was already deprecated since Python 2.6 and is also expected to be removed in Python 3.7. Still, there are many cases in which access to Linux distribution information is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for more information. � N�linuxzUnsupported platform: {0}z/etcz os-releaseZoracleZrhel)ZenterpriseenterpriseZredhatenterpriseworkstationZredhatzA(?:[^)]*\)(.*)\()? *(?:STL )?([\d.+\-a-z]*\d) *(?:esaeler *)?(.+)z(\w+)[-_](release|version)$Zdebian_versionz lsb-releasez oem-releasezsystem-releaseTc C s t j| �S )a$ Return information about the current Linux distribution as a tuple ``(id_name, version, codename)`` with items as follows: * ``id_name``: If *full_distribution_name* is false, the result of :func:`distro.id`. Otherwise, the result of :func:`distro.name`. * ``version``: The result of :func:`distro.version`. * ``codename``: The result of :func:`distro.codename`. The interface of this function is compatible with the original :py:func:`platform.linux_distribution` function, supporting a subset of its parameters. The data it returns may not exactly be the same, because it uses more data sources than the original function, and that may lead to different data if the Linux distribution is not consistent across multiple data sources it provides (there are indeed such distributions ...). Another reason for differences is the fact that the :func:`distro.id` method normalizes the distro ID string to a reliable machine-readable value for a number of popular Linux distributions. )�_distro�linux_distribution)�full_distribution_name� r � /usr/lib/python3.6/distro.pyr ` s r c C s t j� S )a� Return the distro ID of the current Linux distribution, as a machine-readable string. For a number of Linux distributions, the returned distro ID value is *reliable*, in the sense that it is documented and that it does not change across releases of the distribution. This package maintains the following reliable distro ID values: ============== ========================================= Distro ID Distribution ============== ========================================= "ubuntu" Ubuntu "debian" Debian "rhel" RedHat Enterprise Linux "centos" CentOS "fedora" Fedora "sles" SUSE Linux Enterprise Server "opensuse" openSUSE "amazon" Amazon Linux "arch" Arch Linux "cloudlinux" CloudLinux OS "exherbo" Exherbo Linux "gentoo" GenToo Linux "ibm_powerkvm" IBM PowerKVM "kvmibm" KVM for IBM z Systems "linuxmint" Linux Mint "mageia" Mageia "mandriva" Mandriva Linux "parallels" Parallels "pidora" Pidora "raspbian" Raspbian "oracle" Oracle Linux (and Oracle Enterprise Linux) "scientific" Scientific Linux "slackware" Slackware "xenserver" XenServer ============== ========================================= If you have a need to get distros for reliable IDs added into this set, or if you find that the :func:`distro.id` function returns a different distro ID for one of the listed distros, please create an issue in the `distro issue tracker`_. **Lookup hierarchy and transformations:** First, the ID is obtained from the following sources, in the specified order. The first available and non-empty value is used: * the value of the "ID" attribute of the os-release file, * the value of the "Distributor ID" attribute returned by the lsb_release command, * the first part of the file name of the distro release file, The so determined ID value then passes the following transformations, before it is returned by this method: * it is translated to lower case, * blanks (which should not be there anyway) are translated to underscores, * a normalization of the ID is performed, based upon `normalization tables`_. The purpose of this normalization is to ensure that the ID is as reliable as possible, even across incompatible changes in the Linux distributions. A common reason for an incompatible change is the addition of an os-release file, or the addition of the lsb_release command, with ID values that differ from what was previously determined from the distro release file name. )r �idr r r r r | s Hr Fc C s t j| �S )an Return the name of the current Linux distribution, as a human-readable string. If *pretty* is false, the name is returned without version or codename. (e.g. "CentOS Linux") If *pretty* is true, the version and codename are appended. (e.g. "CentOS Linux 7.1.1503 (Core)") **Lookup hierarchy:** The name is obtained from the following sources, in the specified order. The first available and non-empty value is used: * If *pretty* is false: - the value of the "NAME" attribute of the os-release file, - the value of the "Distributor ID" attribute returned by the lsb_release command, - the value of the "<name>" field of the distro release file. * If *pretty* is true: - the value of the "PRETTY_NAME" attribute of the os-release file, - the value of the "Description" attribute returned by the lsb_release command, - the value of the "<name>" field of the distro release file, appended with the value of the pretty version ("<version_id>" and "<codename>" fields) of the distro release file, if available. )r �name)�prettyr r r r � s $r c C s t j| |�S )ay Return the version of the current Linux distribution, as a human-readable string. If *pretty* is false, the version is returned without codename (e.g. "7.0"). If *pretty* is true, the codename in parenthesis is appended, if the codename is non-empty (e.g. "7.0 (Maipo)"). Some distributions provide version numbers with different precisions in the different sources of distribution information. Examining the different sources in a fixed priority order does not always yield the most precise version (e.g. for Debian 8.2, or CentOS 7.1). The *best* parameter can be used to control the approach for the returned version: If *best* is false, the first non-empty version number in priority order of the examined sources is returned. If *best* is true, the most precise version number out of all examined sources is returned. **Lookup hierarchy:** In all cases, the version number is obtained from the following sources. If *best* is false, this order represents the priority order: * the value of the "VERSION_ID" attribute of the os-release file, * the value of the "Release" attribute returned by the lsb_release command, * the version number parsed from the "<version_id>" field of the first line of the distro release file, * the version number parsed from the "PRETTY_NAME" attribute of the os-release file, if it follows the format of the distro release files. * the version number parsed from the "Description" attribute returned by the lsb_release command, if it follows the format of the distro release files. )r �version)r �bestr r r r � s )r c C s t j| �S )a� Return the version of the current Linux distribution as a tuple ``(major, minor, build_number)`` with items as follows: * ``major``: The result of :func:`distro.major_version`. * ``minor``: The result of :func:`distro.minor_version`. * ``build_number``: The result of :func:`distro.build_number`. For a description of the *best* parameter, see the :func:`distro.version` method. )r � version_parts)r r r r r s r c C s t j| �S )a8 Return the major version of the current Linux distribution, as a string, if provided. Otherwise, the empty string is returned. The major version is the first part of the dot-separated version string. For a description of the *best* parameter, see the :func:`distro.version` method. )r � major_version)r r r r r + s r c C s t j| �S )a9 Return the minor version of the current Linux distribution, as a string, if provided. Otherwise, the empty string is returned. The minor version is the second part of the dot-separated version string. For a description of the *best* parameter, see the :func:`distro.version` method. )r � minor_version)r r r r r 8 s r c C s t j| �S )a6 Return the build number of the current Linux distribution, as a string, if provided. Otherwise, the empty string is returned. The build number is the third part of the dot-separated version string. For a description of the *best* parameter, see the :func:`distro.version` method. )r � build_number)r r r r r E s r c C s t j� S )a Return a space-separated list of distro IDs of distributions that are closely related to the current Linux distribution in regards to packaging and programming interfaces, for example distributions the current distribution is a derivative from. **Lookup hierarchy:** This information item is only provided by the os-release file. For details, see the description of the "ID_LIKE" attribute in the `os-release man page <http://www.freedesktop.org/software/systemd/man/os-release.html>`_. )r �liker r r r r R s r c C s t j� S )a� Return the codename for the release of the current Linux distribution, as a string. If the distribution does not have a codename, an empty string is returned. Note that the returned codename is not always really a codename. For example, openSUSE returns "x86_64". This function does not handle such cases in any special way and just returns the string it finds, if any. **Lookup hierarchy:** * the codename within the "VERSION" attribute of the os-release file, if provided, * the value of the "Codename" attribute returned by the lsb_release command, * the value of the "<codename>" field of the distro release file. )r �codenamer r r r r c s r c C s t j| |�S )a� Return certain machine-readable information items about the current Linux distribution in a dictionary, as shown in the following example: .. sourcecode:: python { 'id': 'rhel', 'version': '7.0', 'version_parts': { 'major': '7', 'minor': '0', 'build_number': '' }, 'like': 'fedora', 'codename': 'Maipo' } The dictionary structure and keys are always the same, regardless of which information items are available in the underlying data sources. The values for the various keys are as follows: * ``id``: The result of :func:`distro.id`. * ``version``: The result of :func:`distro.version`. * ``version_parts -> major``: The result of :func:`distro.major_version`. * ``version_parts -> minor``: The result of :func:`distro.minor_version`. * ``version_parts -> build_number``: The result of :func:`distro.build_number`. * ``like``: The result of :func:`distro.like`. * ``codename``: The result of :func:`distro.codename`. For a description of the *pretty* and *best* parameters, see the :func:`distro.version` method. )r �info)r r r r r r { s )r c C s t j� S )z� Return a dictionary containing key-value pairs for the information items from the os-release file data source of the current Linux distribution.

This package creates a private module-global instance of this class with default initialization arguments, that is used by the `consolidated accessor functions`_ and `single source accessor functions`_. By using default initialization arguments, that module-global instance returns data about the current Linux distribution (i.e. the distro this package runs on). Normally, it is not necessary to create additional instances of this class. However, in situations where control is needed over the exact data sources that are used, instances of this class can be created with a specific distro release file, or a specific os-release file, or without invoking the lsb_release command. T� c C sH |pt jjtt�| _|pd| _| j� | _|r4| j � ni | _ | j � | _ dS )a8 The initialization method of this class gathers information from the available data sources, and stores that in private instance attributes. Subsequent access to the information items uses these private instance attributes, so that the data sources are read only once. Parameters: * ``include_lsb`` (bool): Controls whether the `lsb_release command output`_ is included as a data source. If the lsb_release command is not available in the program execution path, the data source for the lsb_release command will be empty. * ``os_release_file`` (string): The path name of the `os-release file`_ that is to be used as a data source. An empty string (the default) will cause the default path name to be used (see `os-release file`_ for details). If the specified or defaulted os-release file does not exist, the data source for the os-release file will be empty. * ``distro_release_file`` (string): The path name of the `distro release file`_ that is to be used as a data source. An empty string (the default) will cause a default search algorithm to be used (see `distro release file`_ for details). If the specified distro release file does not exist, or if no default distro release file can be found, the data source for the distro release file will be empty. Public instance attributes: * ``os_release_file`` (string): The path name of the `os-release file`_ that is actually used as a data source. The empty string if no distro release file is used as a data source. * ``distro_release_file`` (string): The path name of the `distro release file`_ that is actually used as a data source. The empty string if no distro release file is used as a data source. Raises: * :py:exc:`IOError`: Some I/O issue with an os-release file or distro release file. * :py:exc:`subprocess.CalledProcessError`: The lsb_release command had some issue (other than not being available in the program execution path). * :py:exc:`UnicodeError`: A data source has unexpected characters or uses an unexpected encoding. r N) �os�path�join� _UNIXCONFDIR�_OS_RELEASE_BASENAME�os_release_file�distro_release_file�_get_os_release_info�_os_release_info�_get_lsb_release_info�_lsb_release_info�_get_distro_release_info�_distro_release_info)�selfZ include_lsbr" r# r r r �__init__ s ; zLinuxDistribution.__init__c C s dj | j| j| j| j| j�S )z Return repr of all info z�LinuxDistribution(os_release_file={0!r}, distro_release_file={1!r}, _os_release_info={2!r}, _lsb_release_info={3!r}, _distro_release_info={4!r}))�formatr" r# r% r' r) )r* r r r �__repr__U s zLinuxDistribution.__repr__c C s" |r | j � n| j� | j� | j� fS )z� Return information about the Linux distribution that is compatible with Python's :func:`platform.linux_distribution`, supporting a subset of its parameters.
