It is the recommended replacement 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 3.8 removed it altogether. Its predecessor function :py:func:`platform.dist` was already deprecated since Python 2.6 and removed in Python 3.8. Still, there are many cases in which access to OS distribution information is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for more information. � Nz1.6.0Z UNIXCONFDIRz/etcZ UNIXUSRLIBDIRz/usr/libz os-releaseZolZoracleZrhel)ZenterpriseenterpriseasZenterpriseenterpriseserverZredhatenterpriseworkstationZredhatenterpriseserverZredhatenterprisecomputenodeZredhatzA(?:[^)]*\)(.*)\()? *(?:STL )?([\d.+\-a-z]*\d) *(?:esaeler *)?(.+)z(\w+)[-_](release|version)$Zdebian_versionz lsb-releasez oem-releasezsystem-releasez plesk-releaseziredmail-releaseTc C s t jdtdd� t�| �S )aG .. deprecated:: 1.6.0 :func:`distro.linux_distribution()` is deprecated. It should only be used as a compatibility shim with Python's :py:func:`platform.linux_distribution()`. Please use :func:`distro.id`, :func:`distro.version` and :func:`distro.name` instead. Return information about the current OS 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 OS 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 OS distributions. z�distro.linux_distribution() is deprecated.

For a number of OS 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 "openbsd" OpenBSD "netbsd" NetBSD "freebsd" FreeBSD "midnightbsd" MidnightBSD ============== ========================================= 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 OS 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 Mr Fc C s t �| �S )ak Return the name of the current OS 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 �| |�S )av Return the version of the current OS 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 �| �S )a� Return the version of the current OS 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 X s r c C s t �| �S )a5 Return the major version of the current OS distribution, as a string, if provided.

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 � s r c C s t �� S )a� Return the codename for the release of the current OS 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 � s r c C s t �| |�S )a� Return certain machine-readable information items about the current OS 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`.

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 OS 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.

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. * ``include_uname`` (bool): Controls whether uname command output is included as a data source. If the uname command is not available in the program execution path the data source for the uname command will be empty. * ``root_dir`` (string): The absolute path to the root directory to use to find distro-related information files. 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. * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter. This controls whether the lsb information will be loaded. * ``include_uname`` (bool): The result of the ``include_uname`` parameter. This controls whether the uname information will be loaded. 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. �etczusr/libr6 N)�root_dir�os�path�join� _UNIXCONFDIR�etc_dir�_UNIXUSRLIBDIRZ usr_lib_dir�os_release_file�_OS_RELEASE_BASENAME�isfile�distro_release_file� include_lsb� include_uname)r* rC r? rB rD r8 Zetc_dir_os_release_fileZusr_lib_os_release_filer r r r, � s$ O��� zLinuxDistribution.__init__c C s dj | d�S )zReturn repr of all infoae LinuxDistribution(os_release_file={self.os_release_file!r}, distro_release_file={self.distro_release_file!r}, include_lsb={self.include_lsb!r}, include_uname={self.include_uname!r}, _os_release_info={self._os_release_info!r}, _lsb_release_info={self._lsb_release_info!r}, _distro_release_info={self._distro_release_info!r}, _uname_info={self._uname_info!r})�r* )�formatrE r r r �__repr__� s ��zLinuxDistribution.__repr__c C s" |r | � � n| �� | �� | �� fS )z� Return information about the OS distribution that is compatible with Python's :func:`platform.linux_distribution`, supporting a subset of its parameters.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form ``"<salutation>, <addressee>!"``), built up using :class:`Word`, :class:`Literal`, and :class:`And` elements (the :class:`'+'<ParserElement.__add__>` operators create :class:`And` expressions, and the strings are auto-converted to :class:`Literal` expressions):: from pip._vendor.pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The :class:`ParseResults` object returned from :class:`ParserElement.parseString` can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments Getting Started - ----------------- Visit the classes :class:`ParserElement` and :class:`ParseResults` to see the base classes that most other pyparsing classes inherit from. Use the docstrings for examples of how to: - construct literal match expressions from :class:`Literal` and :class:`CaselessLiteral` classes - construct character word-group expressions using the :class:`Word` class - see how to create repetitive expressions using :class:`ZeroOrMore` and :class:`OneOrMore` classes - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`, and :class:`'&'<Each>` operators to combine simple expressions into more complex ones - associate names with your parsed results using :class:`ParserElement.setResultsName` - access the parsed data, which is returned as a :class:`ParseResults` object - find some helpful expression short-cuts like :class:`delimitedList` and :class:`oneOf` - find more useful common expressions in the :class:`pyparsing_common` namespace class z2.4.7z30 Mar 2020 00:43 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)� itemgetter)�wraps)�contextmanager)� filterfalse)� ifilterfalse)�RLock)�Iterable)�MutableMapping�Mapping)� OrderedDict)�SimpleNamespacec @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �9/usr/lib/python3.9/site-packages/pip/_vendor/pyparsing.pyr � � r aA A cross-version compatibility configuration for pyparsing features that will be released in a future version.

Parameters: - exc - exception raised during parsing (need not be a ParseException, in support of Python exceptions that might be raised in a parse action) - depth (default=16) - number of levels back in the stack trace to list expression and function names; if None, the full stack trace names will be listed; if 0, only the failing input line, marker, and exception string will be shown Returns a multi-line string listing the ParserElements and/or function names in the exception's stack trace. Note: the diagnostic output will include string representations of the expressions that failed to parse. These representations will be more helpful if you use `setName` to give identifiable names to your expressions. Otherwise they will use the default string forms, which may be cryptic to read. explain() is only supported under Python 3. r N� r� �^z{0}: {1})�contextr� )� parseImpl� _parseNoCachez {0}.{1} - {2}z{0}.{1})�wrapperz<module>z{0}� )�inspectr� �getrecursionlimitr� r< �appendrg rY �formatr� r Zgetinnerframes� __traceback__�set� enumerate�f_locals�getrC �f_code�co_name�addr r� ) �exc�depthr� r� Zcallers�seen�iZffZfrmZf_selfZ self_type�coder r r �explain� sL � � zParseException.explainN)r� )r r r r� � staticmethodr� r r r r r> k s r> c @ s e Zd ZdZdS )r@ znuser-throwable exception thrown when inconsistent parse content is found; stops all parsing immediatelyN�r r r r� r r r r r@ � s r@ c @ s e Zd ZdZdS )rB z�just like :class:`ParseFatalException`, but thrown internally when an :class:`ErrorStop<And._ErrorStop>` ('-' operator) indicates that parsing is to stop immediately because an unbacktrackable syntax error has been found.

Supports both ``list`` and ``dict`` semantics for ``pop()``. If passed no argument or an integer argument, it will use ``list`` semantics and pop tokens from the list of parsed tokens. If passed a non-integer argument (most likely a string), it will use ``dict`` semantics and pop the corresponding value from any defined results names. A second default return value argument is supported, just as in ``dict.pop()``. Example:: def remove_first(tokens): tokens.pop(0) print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321'] print(OneOrMore(Word(nums)).addParseAction(remove_first).parseString("0 123 321")) # -> ['123', '321'] label = Word(alphas) patt = label("LABEL") + OneOrMore(Word(nums)) print(patt.parseString("AAB 123 321").dump()) # Use pop() in a parse action to remove named result (note that corresponding value is not # removed from list form of results) def remove_LABEL(tokens): tokens.pop("LABEL") return tokens patt.addParseAction(remove_LABEL) print(patt.parseString("AAB 123 321").dump()) prints:: ['AAB', '123', '321'] - LABEL: AAB ['AAB', '123', '321'] r� �defaultr z-pop() got an unexpected keyword argument '%s'r� N)r* r r� r� r� )r� r� �kwargsr# r �indexr� Z defaultvaluer r r �pop� s" % � �zParseResults.popc C s || v r| | S |S dS )a[ Returns named result matching the given key, or if there is no such name, then returns the given ``defaultValue`` or ``None`` if no ``defaultValue`` is specified.

Parse action fn is a callable method with 0-3 arguments, called as ``fn(s, loc, toks)`` , ``fn(loc, toks)`` , ``fn(toks)`` , or just ``fn()`` , where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a :class:`ParseResults` object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. If None is passed as the parse action, all previously added parse actions for this expression are cleared. Optional keyword arguments: - callDuringTry = (default= ``False``) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process. See :class:`parseString for more information on parsing strings containing ``<TAB>`` s, and suggested methods to maintain a consistent view of the parsed string, the parse location, and line and column positions within the parsed string. Example:: integer = Word(nums) date_str = integer + '/' + integer + '/' + integer date_str.parseString("1999/12/31") # -> ['1999', '/', '12', '/', '31'] # use parse action to convert to ints at parse time integer = Word(nums).setParseAction(lambda toks: int(toks[0])) date_str = integer + '/' + integer + '/' + integer # note that integer fields are now ints, not strings date_str.parseString("1999/12/31") # -> [1999, '/', 12, '/', 31] Nc s s | ]}t |�V qd S r� )�callable)r r� r r r r� r z/ParserElement.setParseAction.<locals>.<genexpr>z parse actions must be callabler� F)r r� �allr �mapr� r� r� �r� �fnsrF r r r r� � s (z ParserElement.setParseActionc O s4 | j tttt|���7 _ | jp,|�dd�| _| S )z� Add one or more parse actions to expression's list of parse actions.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default= ``128``) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method :class:`ParserElement.enablePackrat`. For best results, call ``enablePackrat()`` immediately after importing pyparsing. Example:: from pip._vendor import pyparsing pyparsing.ParserElement.enablePackrat() TN)rC �_packratEnabledr r r r r� )Zcache_size_limitr r r � enablePackratJ s zParserElement.enablePackratc C s� t �� | js| �� | jD ] }|�� q | js8|�� }z<| �|d�\}}|rr| �||�}t � t � }|�||� W nP t y� } z8t j r�� n"t |dd�dur�| �|j�|_|�W Y d}~nd}~0 0 |S dS )a� Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. Returns the parsed data as a :class:`ParseResults` object, which may be accessed as a list, or as a dict or object with attributes if the given parser includes results names. If you want the grammar to require that the entire input string be successfully parsed, then set ``parseAll`` to True (equivalent to ending the grammar with ``StringEnd()``). Note: ``parseString`` implicitly calls ``expandtabs()`` on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling ``parseWithTabs`` on your grammar before calling ``parseString`` (see :class:`parseWithTabs`) - define your parse action using the full ``(s, loc, toks)`` signature, and reference the input string using the parse action's ``s`` argument - explictly expand the tabs in your input string before calling ``parseString`` Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r r� N)rC r r� � streamliner� r� � expandtabsr� r� r+ rH r< �verbose_stacktracer� r� r� )r� r� �parseAllr� r� r� Zser� r r r � parseStringm s( ! zParserElement.parseStringc c sV | j s| �� | jD ] }|�� q| js4t|��� }t|�}d}| j}| j}t � � d} z�||kr�| |k r�z |||�} ||| dd�\} } W n t y� | d }Y qZ0 | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }q�| }qZ| d }qZW nV t �yP } z<t j �r� n$t|dd�du�r8| �|j�|_|�W Y d}~n d}~0 0 dS )aq Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional ``maxMatches`` argument, to clip scanning after 'n' matches are found. If ``overlap`` is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See :class:`parseString` for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens, start, end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F�r� r� r� N)r� r r� r� r� r! r� r� r� rC r r> r< r" r� r� r� )r� r� � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr� r r r � scanString� sF zParserElement.scanStringc C s g }d}d| _ z�| �|�D ]Z\}}}|�|||� � |rpt|t�rR||�� 7 }n t|t�rf||7 }n |�|� |}q|�||d� � dd� |D �}d�tt t |���W S t y� } z8t j rĂ n"t|dd�dur�| �|j�|_|�W Y d}~n d}~0 0 dS )a[ Extension to :class:`scanString`, to modify matching text with modified tokens that may be returned from a parse action. To use ``transformString``, define a grammar and attach a parse action to it that modifies the returned token list. Invoking ``transformString()`` on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. ``transformString()`` returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york.")) prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r TNc S s g | ] }|r|�qS r r �r �or r r r r z1ParserElement.transformString.<locals>.<listcomp>r� r� )r� r( r� r� rA r r r� r� r� �_flattenr< rC r" r� r� r� )r� r� rd ZlastEr� r� r� r� r r r r� � s, z ParserElement.transformStringc C sr z t dd� | �||�D ��W S tyl } z8tjr6� n"t|dd�durT| �|j�|_|�W Y d}~n d}~0 0 dS )a� Another extension to :class:`scanString`, simplifying the access to the tokens found to match the given parse expression.

Literal('start') + ... + Literal('end') is equivalent to: Literal('start') + SkipTo('end')("_skipped*") + Literal('end') Note that the skipped text is returned with '_skipped' as a results name, and to support having multiple skips in the same parser, the value returned is a list of all skipped text. �4Cannot combine element of type %s with ParserElementr� �� stacklevelN) �Ellipsis� _PendingSkipr� r r� rC �warnings�warnr� � SyntaxWarningr$ r\ r r r rT Z s �zParserElement.__add__c C sZ |t u rt| �d�| S t|t�r,| �|�}t|t�sRtjdt|� t dd� dS || S )z` Implementation of + operator when left operand is not a :class:`ParserElement` � _skipped*r. r� r/ N) r1 rG r� r r� rC r3 r4 r� r5 r\ r r r r] � s �zParserElement.__radd__c C sJ t |t�r| �|�}t |t�s:tjdt|� tdd� dS | t� � | S )zT Implementation of - operator, returns :class:`And` with error stop r. r� r/ N) r� r r� rC r3 r4 r� r5 r$ � _ErrorStopr\ r r r �__sub__� s �zParserElement.__sub__c C sB t |t�r| �|�}t |t�s:tjdt|� tdd� dS || S )z` Implementation of - operator when left operand is not a :class:`ParserElement` r. r� r/ N�r� r r� rC r3 r4 r� r5 r\ r r r �__rsub__� s �zParserElement.__rsub__c s |t u rd}n8t|t�rF|dd� t fkrFd|dd� d dd� }t|t�r\|d }}n�t|t��rJtdd � |D ��}|d dd� }|d du r�d|d f}t|d t�r�|d du r�|d dkr�t��S |d dkr�t��S �|d t�� S nNt|d t��r,t|d t��r,|\}}||8 }n td t|d �t|d ���ntd t|���|dk �rjtd ��|dk �r|td��|| k�r�dk�r�n ntd��|�r� �fdd�� |�r�|dk�r҈� |� }nt �g| �� |� }n� |�}n |dk�r�}nt �g| �}|S )a� Implementation of * operator, allows use of ``expr * 3`` in place of ``expr + expr + expr``.

Prior to attempting to match the ``wd`` expression, the debugging message ``"Match <exprname> at loc <n>(<line>,<col>)"`` is shown. Then if the parse succeeds, a ``"Matched"`` message is shown, or an ``"Exception raised"`` message is shown. Also note the use of :class:`setName` to assign a human-readable name to the expression, which makes debugging and exception messages easier to understand - for instance, the default name created for the :class:`Word` expression without calling ``setName`` is ``"W:(ABCD...)"``.

Quick and easy way to run a parse expression against a list of sample strings. Parameters: - tests - a list of separate test strings, or a multiline string of test strings - parseAll - (default= ``True``) - flag to pass to :class:`parseString` when running tests - comment - (default= ``'#'``) - expression for indicating embedded comments in the test string; pass None to disable comment filtering - fullDump - (default= ``True``) - dump results as list followed by results names in nested outline; if False, only dump nested list - printResults - (default= ``True``) prints test output to stdout - failureTests - (default= ``False``) indicates if these tests are expected to fail parsing - postParse - (default= ``None``) optional callback for successful parse results; called as `fn(test_string, parse_results)` and returns a string to be added to the test output - file - (default=``None``) optional file-like object to which test output will be written; if None, will default to ``sys.stdout`` Returns: a (success, results) tuple, where success indicates that all tests succeeded (or failed if ``failureTests`` is True), and the results contain a list of lines of each test's output Example:: number_expr = pyparsing_common.number.copy() result = number_expr.runTests(''' # unsigned integer 100 # negative integer -100 # float with scientific notation 6.02e23 # integer with scientific notation 1e-12 ''') print("Success" if result[0] else "Failed!") result = number_expr.runTests(''' # stray character 100Z # missing leading digit before '.' -.100 # too many '.' 3.14.159 ''', failureTests=True) print("Success" if result[0] else "Failed!") prints:: # unsigned integer 100 [100] # negative integer -100 [-100] # float with scientific notation 6.02e23 [6.02e+23] # integer with scientific notation 1e-12 [1e-12] Success # stray character 100Z ^ FAIL: Expected end of text (at char 3), (line:1, col:4) # missing leading digit before '.' -.100 ^ FAIL: Expected {real number with scientific notation | real number | signed integer} (at char 0), (line:1, col:1) # too many '.' 3.14.159 ^ FAIL: Expected end of text (at char 4), (line:1, col:5) Success Each test string must be on a single line.

Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) r� c sB t t| ��� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) rt r� r� r � match_string� maxMismatchesr� r� r� )r� r� r� rv r r r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} tt|||� |��D ]2\}} | \} } | | krL| �|� t | �| krL q�qL|d }t|||� g�}||d< | |d< ||fS t||| j| ��d S )Nr r� �original� mismatches) r� r� r� r� r� r� rA r> r� )r� r� r� r� �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsr r r r� � s( zCloseMatch.parseImpl)r� )Tr~ r r rv r r� � s r� c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )rN aX Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for ``min`` is 1 (a minimum value < 1 is not valid); the default values for ``max`` and ``exact`` are 0, meaning no maximum or exact length restriction. An optional ``excludeChars`` parameter can list characters that might be found in the input ``bodyChars`` string; useful to define a word of all printables except for one or two characters, for instance. :class:`srange` is useful for defining custom character set strings for defining ``Word`` expressions, using range notation from regular expression character sets. A common mistake is to use :class:`Word` to match a specific literal string, as in ``Word("Address")``. Remember that :class:`Word` uses the string argument to define *sets* of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use :class:`Literal` or :class:`Keyword`. pyparsing includes helper strings for building Words: - :class:`alphas` - :class:`nums` - :class:`alphanums` - :class:`hexnums` - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - :class:`punc8bit` (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - :class:`printables` (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums + '-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nr� r Fc s� t t| ��� � rNt� �� d�� fdd�|D ��}|rNd�� fdd�|D ��}|| _t|�| _|rt|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j v�r�|dk�r�|dk�r�|dk�r�| j| jk�r@d t| j� | _nHt| j�dk�rnd t�| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _zt�| j�| _W n t�y� d | _Y n0 | jj| _t | _ d S )Nr� c 3 s | ]}|� vr|V qd S r� r r� �� excludeCharsr r r� H r z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� vr|V qd S r� r r� r� r r r� J r r r� zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedr� Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b) rt rN r� r� r� � initCharsOrig� initChars� bodyCharsOrig� bodyChars� maxSpecifiedrA �minLen�maxLenrr r� r r� r� � asKeyword�_escapeRegexRangeChars�reStringr� r� �escape�compiler� r� �re_match� _WordRegexr� )r� r� r� �min�max�exactr� r� rv r� r r� D sZ 0 � � z Word.__init__Tc C s� || | j vr t||| j| ��|}|d7 }t|�}| j}|| j }t||�}||k rj|| |v rj|d7 }qLd}|| | jk r�d}nV| jr�||k r�|| |v r�d}n6| j r�|dkr�||d |v s�||k r�|| |v r�d}|r�t||| j| ��||||� fS )Nr� FTr ) r� r> r� r� r� r� r� r� r� r� ) r� r� r� r� r� r� Z bodycharsr� ZthrowExceptionr r r r� } s2 � �zWord.parseImplc st zt t| ��� W S ty" Y n0 | jd u rndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� rs r �r� r r r � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s, %s)zW:(%s))rt rN r� r� r� r� r� )r� r� rv r r r� � s z Word.__str__)Nr� r r FN)T�r r r r� r� r� r� rz r r rv r rN s 49 rN c @ s e Zd Zddd�ZdS )r� Tc C s4 | � ||�}|s t||| j| ��|�� }||�� fS r� )r� r> r� �end�group)r� r� r� r� rp r r r r� � s z_WordRegex.parseImplN)Tr� r r r r r� � s r� c s" e Zd ZdZd� fdd� Z� ZS )rR z�A short-cut class for defining ``Word(characters, exact=1)``, when defining a match of any single character in a string of characters.

Defined with string specifying the regular expression in a form recognized by the stdlib Python `re module <https://docs.python.org/3/library/re.html>`_. If the given regex contains named groups (defined using ``(?P<name>...)``), these will be preserved as named parse results. If instead of the Python stdlib re module you wish to use a different RE module (such as the `regex` module), you can replace it by either building your Regex object with a compiled RE that was compiled using regex: Example:: realnum = Regex(r"[+-]?\d+\.\d*") date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)') # ref: https://stackoverflow.com/questions/267399/how-do-you-match-only-valid-roman-numerals-with-a-regular-expression roman = Regex(r"M{0,4}(CM|CD|D?{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})") # use regex module instead of stdlib re module to construct a Regex using # a compiled regular expression import regex parser = pp.Regex(regex.compile(r'[0-9]')) r Fc s" t t| ��� t|t�r�|s,tjdtdd� || _|| _ z t � | j| j �| _ | j| _ W q� t jy� tjd| tdd� � Y q�0 n8t|d�r�t|d�r�|| _ |j | _| _ || _ ntd��| j j| _t| �| _d| j | _d | _| �d �d u| _|| _|| _| j�r| j| _| j�r | j | _d S ) a The parameters ``pattern`` and ``flags`` are passed to the ``re.compile()`` function as-is.

When the expression is known, it is assigned to the ``Forward`` variable using the '<<' operator. Note: take care when assigning to ``Forward`` not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the ``Forward``:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem. See :class:`ParseResults.pprint` for an example of a recursive parser created using ``Forward``.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing ``combine=True`` in the constructor. If ``combine`` is set to ``True``, the matching tokens are returned as a single token string, with the delimiters included; otherwise, the matching tokens are returned as a list of tokens, with the delimiters suppressed. Example:: delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc'] delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE'] z [r� r N)r� r( rQ r� rJ )r� �delim�combineZdlNamer r r r` � s $r` c sj t � � � �fdd�}|du r0tt��dd� �}n|�� }|�d� |j|dd� |� �d t�� d �S ) a> Helper to define a counted list of expressions.

For example:: first = Word(nums) second = matchPreviousLiteral(first) matchExpr = first + ":" + second will match ``"1:1"``, but not ``"1:2"``. Because this matches a previous literal, will also match the leading ``"1:1"`` in ``"1:10"``. If this is not desired, use :class:`matchPreviousExpr`.

The value pattern can include named results, so that the :class:`Dict` results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r) r8 r/ )rI r- r r r ra � s %ra c C s^ t � �dd� �}|�� }d|_|d�| |d� }|r@dd� }ndd� }|�|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional ``asString`` argument is passed as ``False``, then the return value is a :class:`ParseResults` containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to :class:`originalTextFor` contains expressions with defined results names, you must set ``asString`` to ``False`` if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b", "i"): opener, closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S r� r )r� r� r� r r r r� � r z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S r� )rB rC r� r r r r� � r c S s& | |� d�|� d�� g|d d �< d S )NrB rC )rH r� r r r � extractText� s z$originalTextFor.<locals>.extractText)r+ r� rR r� r� )r� ZasStringZ locMarkerZ endlocMarker� matchExprrD r r r r� � s r� c C s t | ��dd� �S )zkHelper to undo pyparsing's default grouping of And expressions, even if all but one are non-empty. c S s | d S r r r� r r r r� r zungroup.<locals>.<lambda>)rL r� )r� r r r r� � s r� c C s4 t � �dd� �}t|d�| d� |�� �� d� �S )a� Helper to decorate a returned token with its starting and ending locations in the input string.

Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as ``\-`` or ``\]``) - an escaped hex character with a leading ``'\x'`` (``\x21``, which is a ``'!'`` character) (``\0x##`` is also supported for backwards compatibility) - an escaped octal character with a leading ``'\0'`` (``\041``, which is a ``'!'`` character) - a range of any of the above, separated by a dash (``'a-z'``, etc.) - any combination of the above (``'aeiouy'``, ``'a-zA-Z0-9_$'``, etc.) c S s< t | t�s| S d�dd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S r� �rG r� r r r r� I r z+srange.<locals>.<lambda>.<locals>.<genexpr>r r� )r� rA r� r' �ord)�pr r r r� I r zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S r� r )r �part�Z _expandedr r r� K r zsrange.<locals>.<genexpr>N)r� �_reBracketExprr$ rJ r� r� r rO r r / s " r c s � fdd�}|S )zoHelper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %dr� )r� Zlocnr� r< r r � verifyColS s z!matchOnlyAtCol.<locals>.verifyColr )r= rQ r r< r rm O s rm c s � fdd�S )a� Helper method for common parse actions that simply return a literal value. Especially useful when used with :class:`transformString<ParserElement.transformString>` (). Example:: num = Word(nums).setParseAction(lambda toks: int(toks[0])) na = oneOf("N/A NA").setParseAction(replaceWith(math.nan)) term = na | num OneOrMore(term).parseString("324 234 N/A 234") # -> [324, 234, nan, 234] c s � gS r� r r� �ZreplStrr r r� e r z replaceWith.<locals>.<lambda>r rR r rR r r| X s r| c C s |d dd� S )a Helper parse action for removing quotation marks from parsed quoted strings.

If any additional args are passed, they are forwarded to the given function as additional arguments after the token, as in ``hex_integer = Word(hexnums).setParseAction(tokenMap(int, 16))``, which will convert the parsed data to an integer using base 16. Example (compare the last to example in :class:`ParserElement.transformString`:: hex_ints = OneOrMore(Word(hexnums)).setParseAction(tokenMap(int, 16)) hex_ints.runTests(''' 00 11 22 aa FF 0a 0d 1a ''') upperword = Word(alphas).setParseAction(tokenMap(str.upper)) OneOrMore(upperword).runTests(''' my kingdom for a horse ''') wd = Word(alphas).setParseAction(tokenMap(str.title)) OneOrMore(wd).setParseAction(' '.join).runTests(''' now is the winter of our discontent made glorious summer by this sun of york ''') prints:: 00 11 22 aa FF 0a 0d 1a [0, 17, 34, 170, 255, 10, 13, 26] my kingdom for a horse ['MY', 'KINGDOM', 'FOR', 'A', 'HORSE'] now is the winter of our discontent made glorious summer by this sun of york ['Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York'] c s � �fdd�|D �S )Nc s g | ]}�|g� �R � �qS r r )r Ztokn�r� r� r r r � r z(tokenMap.<locals>.pa.<locals>.<listcomp>r r� rS r r r� � s ztokenMap.<locals>.par r� )r� r r� r� )r� r� r� r� r rS r r� v s $ � r� c C s t | ��� S r� �r� r� r� r r r r� � r c C s t | ��� S r� �r� �lowerr� r r r r� � r ro rp c s~ t | t�r | � t| | d�} n| j� tttd �}|r�t�� � t �}|| d� t t t |td� | ��� tddgd�d�� d d � � | }nlt�� � t �ttd d �B }|| d� t t t |� t�ttd�| � ��� tddgd�d�� d d � � | }ttd�| d dd�}|�d� � |�� fdd �� |dd�� �dd��� �� � ��d� �}� |_� |_t |� �|_ ||fS )zRInternal helper to construct opening and closing tag expressions, given a tag namer� z_-:�tag�=�/F�rE rc c S s |d dkS �Nr rY r r� r r r r� � r z_makeTags.<locals>.<lambda>rp r� c S s |d dkS r[ r r� r r r r� � r rq )r# z<%s>c s* | � dd�� �dd��� �� � | �� �S )Nr� r� �:r� )r% r� r� �titler� rR r� �Zresnamer r r� � r r� r� r\ r� z</%s>) r� r r0 r rN rT rS r^ rR r� rz r) rQ r/ rJ r: ry rv rb r( �_Lr� r� r� r� r] r� rW rG Ztag_body)�tagStrZxmlZ suppress_LTZ suppress_GTZ tagAttrNameZ tagAttrValueZopenTagZcloseTagr r^ r � _makeTags� sH ���������, ra c C s t | d�S )aK Helper to construct opening and closing tag expressions for HTML, given a tag name.

Use ``withAttribute`` to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as ``<TD>`` or ``<DIV>``. Call ``withAttribute`` with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in ``(align="right")``, or - as an explicit dict with ``**`` operator, when an attribute name is also a Python reserved word, as in ``**{"class":"Customer", "align":"right"}`` - a list of name-value tuples, as in ``(("ns1:class", "Customer"), ("ns2:align", "right"))`` For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for ``class`` (with or without a namespace), use :class:`withClass`. To verify that the attribute exists, but without specifying a value, pass ``withAttribute.ANY_VALUE`` as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS r r rj r r r r / r z!withAttribute.<locals>.<listcomp>c sZ � D ]P\}}||vr$t | |d| ��|tjkr|| |krt | |d||| |f ��qd S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r> r� � ANY_VALUE)r� r� r� ZattrNameZ attrValue��attrsr r r� 0 s �zwithAttribute.<locals>.pa)r* )r� ZattrDictr� r re r r� � s 8 r� c C s" |r d| nd}t f i || i��S )a� Simplified version of :class:`withAttribute` when matching on a div class - made difficult because ``class`` is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See :class:`ParserElement.enablePackrat` for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form ``(opExpr, numTerms, rightLeftAssoc, parseAction)``, where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants ``opAssoc.RIGHT`` and ``opAssoc.LEFT``. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted); if the parse action is passed a tuple or list of functions, this is equivalent to calling ``setParseAction(*fn)`` (:class:`ParserElement.setParseAction`) - lpar - expression for matching left-parentheses (default= ``Suppress('(')``) - rpar - expression for matching right-parentheses (default= ``Suppress(')')``) Example:: # simple example of four-function arithmetic with ints and # variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] c @ s e Zd Zddd�ZdS )zinfixNotation.<locals>._FBTc S s | j �||� |g fS r� )r� r� r� r r r r� � s z$infixNotation.<locals>._FB.parseImplN)Tr� r r r r �_FB� s rj r� Nr� r� z%s termz %s%s termr� z@if numterms=3, opExpr must be a tuple or list of two expressionsr� z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)r, r- r� r� rA r� rt �LEFTr/ r8 �RIGHTr� r: r� r@ r r� )ZbaseExprZopListZlparZrparrj r� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr� ZtermNameZopExpr1ZopExpr2ZthisExprrE r r r r� d s` H� & � & � r� z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|du �r*t| t��r"t|t��r"t| �dkr�t|�dkr�|dur�tt| t| | tj dd� ��� dd� �}n$t � � t| | tj �� dd� � }nx|dur�tt| t | � t |� ttjdd� ��� dd� �}n4ttt | � t |� ttjdd� ��� d d� �}nt d ��t � }|du�rd|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|�d | |f � |S ) a� Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default= ``"("``); can also be a pyparsing expression - closer - closing character for a nested list (default= ``")"``); can also be a pyparsing expression - content - expression for items within the nested lists (default= ``None``) - ignoreExpr - expression for ignoring opening and closing delimiters (default= :class:`quotedString`) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the ``ignoreExpr`` argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an :class:`Or` or :class:`MatchFirst`. The default is :class:`quotedString`, but if no expressions are to be ignored, then pass ``None`` for this argument. Example:: data_type = oneOf("void int short long char float double") decl_data_type = Combine(data_type + Optional(Word('*'))) ident = Word(alphas+'_', alphanums+'_') number = pyparsing_common.number arg = Group(decl_data_type + ident) LPAR, RPAR = map(Suppress, "()") code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment)) c_function = (decl_data_type("type") + ident("name") + LPAR + Optional(delimitedList(arg), [])("args") + RPAR + code_body("body")) c_function.ignore(cStyleComment) source_code = ''' int is_odd(int x) { return (x%2); } int dec_to_hex(char hchar) { if (hchar >= '0' && hchar <= '9') { return (ord(hchar)-ord('0')); } else { return (10+ord(hchar)-ord('A')); } } ''' for func in c_function.searchString(source_code): print("%(name)s (%(type)s) args: %(args)s" % func) prints:: is_odd (int) args: [['int', 'x']] dec_to_hex (int) args: [['char', 'hchar']] z.opening and closing strings cannot be the sameNr� rF c S s | d � � S r �r� r� r r r r� ; r z nestedExpr.<locals>.<lambda>c S s | d � � S r rp r� r r r r� @ r c S s | d � � S r rp r� r r r r� G r c S s | d � � S r rp r� r r r r� L r zOopening and closing arguments must be strings if no content expression is givenznested %s%s expression)rA r� r r� r( r8 r' rC r� r� rc rR r3 r- r/ rJ rQ r� )�openerZcloserZcontentr r� r r r rp � s` A ����� ����� �� � �� *$rp c s& �dd� � � �fdd���fdd�}�fdd�}�fdd �}t t� �d ��� t� d �}t� t� �|� �d �}t� �|��d �}t� �|��d�} |r�tt |�| t |t| � t |� t� d � | �} n.tt |�t |t| � t |� t� d � | �} | � �fdd�� | � t t� � | �d�S )a� Helper method for defining space-delimited indentation blocks, such as those used to define block statements in Python source code.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form ``"<salutation>, <addressee>!"``), built up using :class:`Word`, :class:`Literal`, and :class:`And` elements (the :class:`'+'<ParserElement.__add__>` operators create :class:`And` expressions, and the strings are auto-converted to :class:`Literal` expressions):: from pip._vendor.pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The :class:`ParseResults` object returned from :class:`ParserElement.parseString` can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments Getting Started - ----------------- Visit the classes :class:`ParserElement` and :class:`ParseResults` to see the base classes that most other pyparsing classes inherit from. Use the docstrings for examples of how to: - construct literal match expressions from :class:`Literal` and :class:`CaselessLiteral` classes - construct character word-group expressions using the :class:`Word` class - see how to create repetitive expressions using :class:`ZeroOrMore` and :class:`OneOrMore` classes - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`, and :class:`'&'<Each>` operators to combine simple expressions into more complex ones - associate names with your parsed results using :class:`ParserElement.setResultsName` - access the parsed data, which is returned as a :class:`ParseResults` object - find some helpful expression short-cuts like :class:`delimitedList` and :class:`oneOf` - find more useful common expressions in the :class:`pyparsing_common` namespace class z2.4.7z30 Mar 2020 00:43 UTCz*Paul McGuire <ptmcg@users.sourceforge.net>� N)�ref)�datetime)� itemgetter)�wraps)�contextmanager)� filterfalse)� ifilterfalse)�RLock)�Iterable)�MutableMapping�Mapping)� OrderedDict)�SimpleNamespacec @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �9/usr/lib/python3.9/site-packages/pip/_vendor/pyparsing.pyr � � r aA A cross-version compatibility configuration for pyparsing features that will be released in a future version.

Note: the diagnostic output will include string representations of the expressions that failed to parse.

Supports both ``list`` and ``dict`` semantics for ``pop()``. If passed no argument or an integer argument, it will use ``list`` semantics and pop tokens from the list of parsed tokens. If passed a non-integer argument (most likely a string), it will use ``dict`` semantics and pop the corresponding value from any defined results names. A second default return value argument is supported, just as in ``dict.pop()``. Example:: def remove_first(tokens): tokens.pop(0) print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321'] print(OneOrMore(Word(nums)).addParseAction(remove_first).parseString("0 123 321")) # -> ['123', '321'] label = Word(alphas) patt = label("LABEL") + OneOrMore(Word(nums)) print(patt.parseString("AAB 123 321").dump()) # Use pop() in a parse action to remove named result (note that corresponding value is not # removed from list form of results) def remove_LABEL(tokens): tokens.pop("LABEL") return tokens patt.addParseAction(remove_LABEL) print(patt.parseString("AAB 123 321").dump()) prints:: ['AAB', '123', '321'] - LABEL: AAB ['AAB', '123', '321'] r� �defaultr z-pop() got an unexpected keyword argument '%s'r� N)r* r r� r� r� )r� r� �kwargsr# r �indexr� Z defaultvaluer r r �pop� s" % � �zParseResults.popc C s || v r| | S |S dS )a[ Returns named result matching the given key, or if there is no such name, then returns the given ``defaultValue`` or ``None`` if no ``defaultValue`` is specified.

Parse action fn is a callable method with 0-3 arguments, called as ``fn(s, loc, toks)`` , ``fn(loc, toks)`` , ``fn(toks)`` , or just ``fn()`` , where: - s = the original string being parsed (see note below) - loc = the location of the matching substring - toks = a list of the matched tokens, packaged as a :class:`ParseResults` object If the functions in fns modify the tokens, they can return them as the return value from fn, and the modified list of tokens will replace the original. Otherwise, fn does not need to return any value. If None is passed as the parse action, all previously added parse actions for this expression are cleared. Optional keyword arguments: - callDuringTry = (default= ``False``) indicate if parse action should be run during lookaheads and alternate testing Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process.

Repeated parse attempts at the same string location (which happens often in many complex grammars) can immediately return a cached value, instead of re-executing parsing/validating code. Memoizing is done of both valid results and parsing exceptions. Parameters: - cache_size_limit - (default= ``128``) - if an integer value is provided will limit the size of the packrat cache; if None is passed, then the cache size will be unbounded; if 0 is passed, the cache will be effectively disabled. This speedup may break existing programs that use parse actions that have side-effects. For this reason, packrat parsing is disabled when you first import pyparsing. To activate the packrat feature, your program must call the class method :class:`ParserElement.enablePackrat`. For best results, call ``enablePackrat()`` immediately after importing pyparsing. Example:: from pip._vendor import pyparsing pyparsing.ParserElement.enablePackrat() TN)rC �_packratEnabledr r r r r� )Zcache_size_limitr r r � enablePackratJ s zParserElement.enablePackratc C s� t �� | js| �� | jD ] }|�� q | js8|�� }z<| �|d�\}}|rr| �||�}t � t � }|�||� W nP t y� } z8t j r�� n"t |dd�dur�| �|j�|_|�W Y d}~nd}~0 0 |S dS )a� Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. Returns the parsed data as a :class:`ParseResults` object, which may be accessed as a list, or as a dict or object with attributes if the given parser includes results names. If you want the grammar to require that the entire input string be successfully parsed, then set ``parseAll`` to True (equivalent to ending the grammar with ``StringEnd()``). Note: ``parseString`` implicitly calls ``expandtabs()`` on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling ``parseWithTabs`` on your grammar before calling ``parseString`` (see :class:`parseWithTabs`) - define your parse action using the full ``(s, loc, toks)`` signature, and reference the input string using the parse action's ``s`` argument - explictly expand the tabs in your input string before calling ``parseString`` Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text r r� N)rC r r� � streamliner� r� � expandtabsr� r� r+ rH r< �verbose_stacktracer� r� r� )r� r� �parseAllr� r� r� Zser� r r r � parseStringm s( ! zParserElement.parseStringc c sV | j s| �� | jD ] }|�� q| js4t|��� }t|�}d}| j}| j}t � � d} z�||kr�| |k r�z |||�} ||| dd�\} } W n t y� | d }Y qZ0 | |kr�| d7 } | | | fV |r�|||�} | |kr�| }q�|d7 }q�| }qZ| d }qZW nV t �yP } z<t j �r� n$t|dd�du�r8| �|j�|_|�W Y d}~n d}~0 0 dS )aq Scan the input string for expression matches. Each match will return the matching tokens, start location, and end location. May be called with optional ``maxMatches`` argument, to clip scanning after 'n' matches are found. If ``overlap`` is specified, then overlapping matches will be reported. Note that the start and end locations are reported relative to the string being parsed. See :class:`parseString` for more information on parsing strings with embedded tabs. Example:: source = "sldjf123lsdjjkf345sldkjf879lkjsfd987" print(source) for tokens, start, end in Word(alphas).scanString(source): print(' '*start + '^'*(end-start)) print(' '*start + tokens[0]) prints:: sldjf123lsdjjkf345sldkjf879lkjsfd987 ^^^^^ sldjf ^^^^^^^ lsdjjkf ^^^^^^ sldkjf ^^^^^^ lkjsfd r F�r� r� r� N)r� r r� r� r� r! r� r� r� rC r r> r< r" r� r� r� )r� r� � maxMatchesZoverlapr� r� r� Z preparseFnZparseFn�matchesr� ZnextLocr� Znextlocr� r r r � scanString� sF zParserElement.scanStringc C s g }d}d| _ z�| �|�D ]Z\}}}|�|||� � |rpt|t�rR||�� 7 }n t|t�rf||7 }n |�|� |}q|�||d� � dd� |D �}d�tt t |���W S t y� } z8t j rĂ n"t|dd�dur�| �|j�|_|�W Y d}~n d}~0 0 dS )a[ Extension to :class:`scanString`, to modify matching text with modified tokens that may be returned from a parse action. To use ``transformString``, define a grammar and attach a parse action to it that modifies the returned token list. Invoking ``transformString()`` on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. ``transformString()`` returns the resulting transformed string. Example:: wd = Word(alphas) wd.setParseAction(lambda toks: toks[0].title()) print(wd.transformString("now is the winter of our discontent made glorious summer by this sun of york.")) prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r TNc S s g | ] }|r|�qS r r �r �or r r r r z1ParserElement.transformString.<locals>.<listcomp>r� r� )r� r( r� r� rA r r r� r� r� �_flattenr< rC r" r� r� r� )r� r� rd ZlastEr� r� r� r� r r r r� � s, z ParserElement.transformStringc C sr z t dd� | �||�D ��W S tyl } z8tjr6� n"t|dd�durT| �|j�|_|�W Y d}~n d}~0 0 dS )a� Another extension to :class:`scanString`, simplifying the access to the tokens found to match the given parse expression.

Prior to attempting to match the ``wd`` expression, the debugging message ``"Match <exprname> at loc <n>(<line>,<col>)"`` is shown. Then if the parse succeeds, a ``"Matched"`` message is shown, or an ``"Exception raised"`` message is shown. Also note the use of :class:`setName` to assign a human-readable name to the expression, which makes debugging and exception messages easier to understand - for instance, the default name created for the :class:`Word` expression without calling ``setName`` is ``"W:(ABCD...)"``.

Quick and easy way to run a parse expression against a list of sample strings. Parameters: - tests - a list of separate test strings, or a multiline string of test strings - parseAll - (default= ``True``) - flag to pass to :class:`parseString` when running tests - comment - (default= ``'#'``) - expression for indicating embedded comments in the test string; pass None to disable comment filtering - fullDump - (default= ``True``) - dump results as list followed by results names in nested outline; if False, only dump nested list - printResults - (default= ``True``) prints test output to stdout - failureTests - (default= ``False``) indicates if these tests are expected to fail parsing - postParse - (default= ``None``) optional callback for successful parse results; called as `fn(test_string, parse_results)` and returns a string to be added to the test output - file - (default=``None``) optional file-like object to which test output will be written; if None, will default to ``sys.stdout`` Returns: a (success, results) tuple, where success indicates that all tests succeeded (or failed if ``failureTests`` is True), and the results contain a list of lines of each test's output Example:: number_expr = pyparsing_common.number.copy() result = number_expr.runTests(''' # unsigned integer 100 # negative integer -100 # float with scientific notation 6.02e23 # integer with scientific notation 1e-12 ''') print("Success" if result[0] else "Failed!") result = number_expr.runTests(''' # stray character 100Z # missing leading digit before '.' -.100 # too many '.' 3.14.159 ''', failureTests=True) print("Success" if result[0] else "Failed!") prints:: # unsigned integer 100 [100] # negative integer -100 [-100] # float with scientific notation 6.02e23 [6.02e+23] # integer with scientific notation 1e-12 [1e-12] Success # stray character 100Z ^ FAIL: Expected end of text (at char 3), (line:1, col:4) # missing leading digit before '.' -.100 ^ FAIL: Expected {real number with scientific notation | real number | signed integer} (at char 0), (line:1, col:1) # too many '.' 3.14.159 ^ FAIL: Expected end of text (at char 4), (line:1, col:5) Success Each test string must be on a single line.

Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2) patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) r� c sB t t| ��� || _|| _|| _d| j| jf | _d| _d| _d S )Nz&Expected %r (with up to %d mismatches)F) rt r� r� r � match_string� maxMismatchesr� r� r� )r� r� r� rv r r r� � s zCloseMatch.__init__Tc C s� |}t |�}|t | j� }||kr�| j}d}g } | j} tt|||� |��D ]2\}} | \} } | | krL| �|� t | �| krL q�qL|d }t|||� g�}||d< | |d< ||fS t||| j| ��d S )Nr r� �original� mismatches) r� r� r� r� r� r� rA r> r� )r� r� r� r� �startr� �maxlocr� Zmatch_stringlocr� r� Zs_m�src�mat�resultsr r r r� � s( zCloseMatch.parseImpl)r� )Tr~ r r rv r r� � s r� c s8 e Zd ZdZd � fdd� Zdd d �Z� fd d �Z� ZS )rN aX Token for matching words composed of allowed character sets. Defined with string containing all allowed initial characters, an optional string containing allowed body characters (if omitted, defaults to the initial character set), and an optional minimum, maximum, and/or exact length. The default value for ``min`` is 1 (a minimum value < 1 is not valid); the default values for ``max`` and ``exact`` are 0, meaning no maximum or exact length restriction. An optional ``excludeChars`` parameter can list characters that might be found in the input ``bodyChars`` string; useful to define a word of all printables except for one or two characters, for instance. :class:`srange` is useful for defining custom character set strings for defining ``Word`` expressions, using range notation from regular expression character sets. A common mistake is to use :class:`Word` to match a specific literal string, as in ``Word("Address")``. Remember that :class:`Word` uses the string argument to define *sets* of matchable characters. This expression would match "Add", "AAA", "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an exact literal string, use :class:`Literal` or :class:`Keyword`. pyparsing includes helper strings for building Words: - :class:`alphas` - :class:`nums` - :class:`alphanums` - :class:`hexnums` - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - :class:`punc8bit` (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - :class:`printables` (any non-whitespace character) Example:: # a word composed of digits integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9")) # a word with a leading capital, and zero or more lowercase capital_word = Word(alphas.upper(), alphas.lower()) # hostnames are alphanumeric, with leading alpha, and '-' hostname = Word(alphas, alphanums + '-') # roman numeral (not a strict parser, accepts invalid mix of characters) roman = Word("IVXLCDM") # any string of non-whitespace characters, except for ',' csv_value = Word(printables, excludeChars=",") Nr� r Fc s� t t| ��� � rNt� �� d�� fdd�|D ��}|rNd�� fdd�|D ��}|| _t|�| _|rt|| _t|�| _n|| _t|�| _|dk| _ |dk r�t d��|| _ |dkr�|| _ nt | _ |dkr�|| _ || _ t| �| _d| j | _d | _|| _d | j| j v�r�|dk�r�|dk�r�|dk�r�| j| jk�r@d t| j� | _nHt| j�dk�rnd t�| j�t| j�f | _nd t| j�t| j�f | _| j�r�d| j d | _zt�| j�| _W n t�y� d | _Y n0 | jj| _t | _ d S )Nr� c 3 s | ]}|� vr|V qd S r� r r� �� excludeCharsr r r� H r z Word.__init__.<locals>.<genexpr>c 3 s | ]}|� vr|V qd S r� r r� r� r r r� J r r r� zZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permittedr� Fr� z[%s]+z%s[%s]*z [%s][%s]*z\b) rt rN r� r� r� � initCharsOrig� initChars� bodyCharsOrig� bodyChars� maxSpecifiedrA �minLen�maxLenrr r� r r� r� � asKeyword�_escapeRegexRangeChars�reStringr� r� �escape�compiler� r� �re_match� _WordRegexr� )r� r� r� �min�max�exactr� r� rv r� r r� D sZ 0 � � z Word.__init__Tc C s� || | j vr t||| j| ��|}|d7 }t|�}| j}|| j }t||�}||k rj|| |v rj|d7 }qLd}|| | jk r�d}nV| jr�||k r�|| |v r�d}n6| j r�|dkr�||d |v s�||k r�|| |v r�d}|r�t||| j| ��||||� fS )Nr� FTr ) r� r> r� r� r� r� r� r� r� r� ) r� r� r� r� r� r� Z bodycharsr� ZthrowExceptionr r r r� } s2 � �zWord.parseImplc st zt t| ��� W S ty" Y n0 | jd u rndd� }| j| jkr^d|| j�|| j�f | _nd|| j� | _| jS )Nc S s$ t | �dkr | d d� d S | S d S )N� rs r �r� r r r � charsAsStr� s z Word.__str__.<locals>.charsAsStrz W:(%s, %s)zW:(%s))rt rN r� r� r� r� r� )r� r� rv r r r� � s z Word.__str__)Nr� r r FN)T�r r r r� r� r� r� rz r r rv r rN s 49 rN c @ s e Zd Zddd�ZdS )r� Tc C s4 | � ||�}|s t||| j| ��|�� }||�� fS r� )r� r> r� �end�group)r� r� r� r� rp r r r r� � s z_WordRegex.parseImplN)Tr� r r r r r� � s r� c s" e Zd ZdZd� fdd� Z� ZS )rR z�A short-cut class for defining ``Word(characters, exact=1)``, when defining a match of any single character in a string of characters.

If the given regex contains named groups (defined using ``(?P<name>...)``), these will be preserved as named parse results. If instead of the Python stdlib re module you wish to use a different RE module (such as the `regex` module), you can replace it by either building your Regex object with a compiled RE that was compiled using regex: Example:: realnum = Regex(r"[+-]?\d+\.\d*") date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)') # ref: https://stackoverflow.com/questions/267399/how-do-you-match-only-valid-roman-numerals-with-a-regular-expression roman = Regex(r"M{0,4}(CM|CD|D?{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})") # use regex module instead of stdlib re module to construct a Regex using # a compiled regular expression import regex parser = pp.Regex(regex.compile(r'[0-9]')) r Fc s" t t| ��� t|t�r�|s,tjdtdd� || _|| _ z t � | j| j �| _ | j| _ W q� t jy� tjd| tdd� � Y q�0 n8t|d�r�t|d�r�|| _ |j | _| _ || _ ntd��| j j| _t| �| _d| j | _d | _| �d �d u| _|| _|| _| j�r| j| _| j�r | j | _d S ) a The parameters ``pattern`` and ``flags`` are passed to the ``re.compile()`` function as-is.

When the expression is known, it is assigned to the ``Forward`` variable using the '<<' operator. Note: take care when assigning to ``Forward`` not to overlook precedence of operators. Specifically, '|' has a lower precedence than '<<', so that:: fwdExpr << a | b | c will actually be evaluated as:: (fwdExpr << a) | b | c thereby leaving b and c out as parseable alternatives. It is recommended that you explicitly group the values inserted into the ``Forward``:: fwdExpr << (a | b | c) Converting to use the '<<=' operator instead will avoid this problem. See :class:`ParseResults.pprint` for an example of a recursive parser created using ``Forward``.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing ``combine=True`` in the constructor. If ``combine`` is set to ``True``, the matching tokens are returned as a single token string, with the delimiters included; otherwise, the matching tokens are returned as a list of tokens, with the delimiters suppressed. Example:: delimitedList(Word(alphas)).parseString("aa,bb,cc") # -> ['aa', 'bb', 'cc'] delimitedList(Word(hexnums), delim=':', combine=True).parseString("AA:BB:CC:DD:EE") # -> ['AA:BB:CC:DD:EE'] z [r� r N)r� r( rQ r� rJ )r� �delim�combineZdlNamer r r r` � s $r` c sj t � � � �fdd�}|du r0tt��dd� �}n|�� }|�d� |j|dd� |� �d t�� d �S ) a> Helper to define a counted list of expressions.

Parameters: - strs - a string of space-delimited literals, or a collection of string literals - caseless - (default= ``False``) - treat all literals as caseless - useRegex - (default= ``True``) - as an optimization, will generate a Regex object; otherwise, will generate a :class:`MatchFirst` object (if ``caseless=True`` or ``asKeyword=True``, or if creating a :class:`Regex` raises an exception) - asKeyword - (default=``False``) - enforce Keyword-style matching on the generated expressions Example:: comp_oper = oneOf("< = > <= >= !=") var = Word(alphas) number = Word(nums) term = var | number comparison_expr = term + comp_oper + term print(comparison_expr.searchString("B = 12 AA=23 B<=AA AA>12")) prints:: [['B', '=', '12'], ['AA', '=', '23'], ['B', '<=', 'AA'], ['AA', '>', '12']] z_More than one string argument passed to oneOf, pass choices as a list or space-delimited stringr� r/ c S s | � � |� � kS r� )r� �rU �br r r r� { r zoneOf.<locals>.<lambda>c S s |� � �| � � �S r� )r� r r= r r r r� | r c S s | |kS r� r r= r r r r� r c S s |� | �S r� r r= r r r r� � r z6Invalid argument to oneOf, expected string or iterabler r� Nr� r� c s s | ]}t |�V qd S r� )r� �r Zsymr r r r� � r zoneOf.<locals>.<genexpr>r �|c s s | ]}t �|�V qd S r� )r� r� r? r r r r� � r z7Exception creating Regex for oneOf, building MatchFirstc 3 s | ]}� |�V qd S r� r r? �ZparseElementClassr r r� � r )r� r r3 r4 r% r& r0 r3 r� r r r5 r6 r� r� rK r� rF r� r� r5 ) Zstrsr� ZuseRegexr� ZisequalZmasksZsymbolsr� Zcurr, rS r rA r rs V sX � � **� rs c C s t tt| | ���S )a� Helper to easily and clearly define a dictionary by specifying the respective patterns for the key and value. Takes care of defining the :class:`Dict`, :class:`ZeroOrMore`, and :class:`Group` tokens in the proper order. The key pattern can include delimiting markers or punctuation, as long as they are suppressed, thereby leaving the significant key text. The value pattern can include named results, so that the :class:`Dict` results can include named token fields. Example:: text = "shape: SQUARE posn: upper left color: light blue texture: burlap" attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)) print(OneOrMore(attr_expr).parseString(text).dump()) attr_label = label attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join) # similar to Dict, but simpler call format result = dictOf(attr_label, attr_value).parseString(text) print(result.dump()) print(result['shape']) print(result.shape) # object attribute access works too print(result.asDict()) prints:: [['shape', 'SQUARE'], ['posn', 'upper left'], ['color', 'light blue'], ['texture', 'burlap']] - color: light blue - posn: upper left - shape: SQUARE - texture: burlap SQUARE SQUARE {'color': 'light blue', 'shape': 'SQUARE', 'posn': 'upper left', 'texture': 'burlap'} )r) r8 r/ )rI r- r r r ra � s %ra c C s^ t � �dd� �}|�� }d|_|d�| |d� }|r@dd� }ndd� }|�|� | j|_|S ) a� Helper to return the original, untokenized text for a given expression. Useful to restore the parsed fields of an HTML start tag into the raw tag text itself, or to revert separate tokens with intervening whitespace back to the original matching input text. By default, returns astring containing the original parsed text. If the optional ``asString`` argument is passed as ``False``, then the return value is a :class:`ParseResults` containing any results names that were originally matched, and a single token containing the original matched text from the input string. So if the expression passed to :class:`originalTextFor` contains expressions with defined results names, you must set ``asString`` to ``False`` if you want to preserve those results name values. Example:: src = "this is test <b> bold <i>text</i> </b> normal text " for tag in ("b", "i"): opener, closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: ['<b> bold <i>text</i> </b>'] ['<i>text</i>'] c S s |S r� r )r� r� r� r r r r� � r z!originalTextFor.<locals>.<lambda>F�_original_start� _original_endc S s | |j |j� S r� )rB rC r� r r r r� � r c S s& | |� d�|� d�� g|d d �< d S )NrB rC )rH r� r r r � extractText� s z$originalTextFor.<locals>.extractText)r+ r� rR r� r� )r� ZasStringZ locMarkerZ endlocMarker� matchExprrD r r r r� � s r� c C s t | ��dd� �S )zkHelper to undo pyparsing's default grouping of And expressions, even if all but one are non-empty. c S s | d S r r r� r r r r� r zungroup.<locals>.<lambda>)rL r� )r� r r r r� � s r� c C s4 t � �dd� �}t|d�| d� |�� �� d� �S )a� Helper to decorate a returned token with its starting and ending locations in the input string. This helper adds the following results names: - locn_start = location where matched expression begins - locn_end = location where matched expression ends - value = the actual parsed results Be careful if the input text contains ``<TAB>`` characters, you may want to call :class:`ParserElement.parseWithTabs` Example:: wd = Word(alphas) for match in locatedExpr(wd).searchString("ljsdf123lksdjjf123lkkjj1222"): print(match) prints:: [[0, 'ljsdf', 5]] [[8, 'lksdjjf', 15]] [[18, 'lkkjj', 23]] c S s |S r� r r� r r r r� r z locatedExpr.<locals>.<lambda>Z locn_startr- Zlocn_end)r+ r� r/ rR rO )r� Zlocatorr r r r� s r� rc ri rh r� r� z\[]-*.$+^?()~ �r� c C s |d d S r& r r� r r r r� ( r r� z\\0?[xX][0-9a-fA-F]+c C s t t|d �d�d��S )Nr z\0xr� )�unichrr� rk r� r r r r� ) r z \\0[0-7]+c C s t t|d dd � d��S )Nr r� � )rG r� r� r r r r� * r z\]r� r^ r� �negate�bodyra c sD dd� � z"d� � fdd�t�| �jD ��W S ty> Y dS 0 dS )a Helper to easily define string ranges for use in Word construction. Borrows syntax from regexp '[]' string range definitions:: srange("[0-9]") -> "0123456789" srange("[a-z]") -> "abcdefghijklmnopqrstuvwxyz" srange("[a-z$_]") -> "abcdefghijklmnopqrstuvwxyz$_" The input string must be enclosed in []'s, and the returned string is the expanded character set joined into a single string. The values enclosed in the []'s may be: - a single character - an escaped character with a leading backslash (such as ``\-`` or ``\]``) - an escaped hex character with a leading ``'\x'`` (``\x21``, which is a ``'!'`` character) (``\0x##`` is also supported for backwards compatibility) - an escaped octal character with a leading ``'\0'`` (``\041``, which is a ``'!'`` character) - a range of any of the above, separated by a dash (``'a-z'``, etc.) - any combination of the above (``'aeiouy'``, ``'a-zA-Z0-9_$'``, etc.) c S s< t | t�s| S d�dd� tt| d �t| d �d �D ��S )Nr� c s s | ]}t |�V qd S r� �rG r� r r r r� I r z+srange.<locals>.<lambda>.<locals>.<genexpr>r r� )r� rA r� r' �ord)�pr r r r� I r zsrange.<locals>.<lambda>r� c 3 s | ]}� |�V qd S r� r )r �part�Z _expandedr r r� K r zsrange.<locals>.<genexpr>N)r� �_reBracketExprr$ rJ r� r� r rO r r / s " r c s � fdd�}|S )zoHelper method for defining parse actions that require matching at a specific column in the input text. c s" t || �� kr t| |d� ��d S )Nz matched token not at column %dr� )r� Zlocnr� r< r r � verifyColS s z!matchOnlyAtCol.<locals>.verifyColr )r= rQ r r< r rm O s rm c s � fdd�S )a� Helper method for common parse actions that simply return a literal value.

If any additional args are passed, they are forwarded to the given function as additional arguments after the token, as in ``hex_integer = Word(hexnums).setParseAction(tokenMap(int, 16))``, which will convert the parsed data to an integer using base 16. Example (compare the last to example in :class:`ParserElement.transformString`:: hex_ints = OneOrMore(Word(hexnums)).setParseAction(tokenMap(int, 16)) hex_ints.runTests(''' 00 11 22 aa FF 0a 0d 1a ''') upperword = Word(alphas).setParseAction(tokenMap(str.upper)) OneOrMore(upperword).runTests(''' my kingdom for a horse ''') wd = Word(alphas).setParseAction(tokenMap(str.title)) OneOrMore(wd).setParseAction(' '.join).runTests(''' now is the winter of our discontent made glorious summer by this sun of york ''') prints:: 00 11 22 aa FF 0a 0d 1a [0, 17, 34, 170, 255, 10, 13, 26] my kingdom for a horse ['MY', 'KINGDOM', 'FOR', 'A', 'HORSE'] now is the winter of our discontent made glorious summer by this sun of york ['Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York'] c s � �fdd�|D �S )Nc s g | ]}�|g� �R � �qS r r )r Ztokn�r� r� r r r � r z(tokenMap.<locals>.pa.<locals>.<listcomp>r r� rS r r r� � s ztokenMap.<locals>.par r� )r� r r� r� )r� r� r� r� r rS r r� v s $ � r� c C s t | ��� S r� �r� r� r� r r r r� � r c C s t | ��� S r� �r� �lowerr� r r r r� � r ro rp c s~ t | t�r | � t| | d�} n| j� tttd �}|r�t�� � t �}|| d� t t t |td� | ��� tddgd�d�� d d � � | }nlt�� � t �ttd d �B }|| d� t t t |� t�ttd�| � ��� tddgd�d�� d d � � | }ttd�| d dd�}|�d� � |�� fdd �� |dd�� �dd��� �� � ��d� �}� |_� |_t |� �|_ ||fS )zRInternal helper to construct opening and closing tag expressions, given a tag namer� z_-:�tag�=�/F�rE rc c S s |d dkS �Nr rY r r� r r r r� � r z_makeTags.<locals>.<lambda>rp r� c S s |d dkS r[ r r� r r r r� � r rq )r# z<%s>c s* | � dd�� �dd��� �� � | �� �S )Nr� r� �:r� )r% r� r� �titler� rR r� �Zresnamer r r� � r r� r� r\ r� z</%s>) r� r r0 r rN rT rS r^ rR r� rz r) rQ r/ rJ r: ry rv rb r( �_Lr� r� r� r� r] r� rW rG Ztag_body)�tagStrZxmlZ suppress_LTZ suppress_GTZ tagAttrNameZ tagAttrValueZopenTagZcloseTagr r^ r � _makeTags� sH ���������, ra c C s t | d�S )aK Helper to construct opening and closing tag expressions for HTML, given a tag name.

Use ``withAttribute`` to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as ``<TD>`` or ``<DIV>``. Call ``withAttribute`` with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in ``(align="right")``, or - as an explicit dict with ``**`` operator, when an attribute name is also a Python reserved word, as in ``**{"class":"Customer", "align":"right"}`` - a list of name-value tuples, as in ``(("ns1:class", "Customer"), ("ns2:align", "right"))`` For attribute names with a namespace prefix, you must use the second form. Attribute names are matched insensitive to upper/lower case. If just testing for ``class`` (with or without a namespace), use :class:`withClass`. To verify that the attribute exists, but without specifying a value, pass ``withAttribute.ANY_VALUE`` as the value. Example:: html = ''' <div> Some text <div type="grid">1 4 0 1 0</div> <div type="graph">1,3 2,3 1,1</div> <div>this has no type</div> </div> ''' div,div_end = makeHTMLTags("div") # only match div tag having a type attribute with value "grid" div_grid = div().setParseAction(withAttribute(type="grid")) grid_expr = div_grid + SkipTo(div | div_end)("body") for grid_header in grid_expr.searchString(html): print(grid_header.body) # construct a match with any div tag having a type attribute, regardless of the value div_any_type = div().setParseAction(withAttribute(type=withAttribute.ANY_VALUE)) div_expr = div_any_type + SkipTo(div | div_end)("body") for div_header in div_expr.searchString(html): print(div_header.body) prints:: 1 4 0 1 0 1 4 0 1 0 1,3 2,3 1,1 Nc S s g | ]\}}||f�qS r r rj r r r r / r z!withAttribute.<locals>.<listcomp>c sZ � D ]P\}}||vr$t | |d| ��|tjkr|| |krt | |d||| |f ��qd S )Nzno matching attribute z+attribute '%s' has value '%s', must be '%s')r> r� � ANY_VALUE)r� r� r� ZattrNameZ attrValue��attrsr r r� 0 s �zwithAttribute.<locals>.pa)r* )r� ZattrDictr� r re r r� � s 8 r� c C s" |r d| nd}t f i || i��S )a� Simplified version of :class:`withAttribute` when matching on a div class - made difficult because ``class`` is a reserved word in Python.

Operators may be unary or binary, left- or right-associative. Parse actions can also be attached to operator expressions. The generated parser will also recognize the use of parentheses to override operator precedences (see example below). Note: if you define a deep operator list, you may see performance issues when using infixNotation. See :class:`ParserElement.enablePackrat` for a mechanism to potentially improve your parser performance. Parameters: - baseExpr - expression representing the most basic element for the nested - opList - list of tuples, one for each operator precedence level in the expression grammar; each tuple is of the form ``(opExpr, numTerms, rightLeftAssoc, parseAction)``, where: - opExpr is the pyparsing expression for the operator; may also be a string, which will be converted to a Literal; if numTerms is 3, opExpr is a tuple of two expressions, for the two operators separating the 3 terms - numTerms is the number of terms for this operator (must be 1, 2, or 3) - rightLeftAssoc is the indicator whether the operator is right or left associative, using the pyparsing-defined constants ``opAssoc.RIGHT`` and ``opAssoc.LEFT``. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted); if the parse action is passed a tuple or list of functions, this is equivalent to calling ``setParseAction(*fn)`` (:class:`ParserElement.setParseAction`) - lpar - expression for matching left-parentheses (default= ``Suppress('(')``) - rpar - expression for matching right-parentheses (default= ``Suppress(')')``) Example:: # simple example of four-function arithmetic with ints and # variable names integer = pyparsing_common.signed_integer varname = pyparsing_common.identifier arith_expr = infixNotation(integer | varname, [ ('-', 1, opAssoc.RIGHT), (oneOf('* /'), 2, opAssoc.LEFT), (oneOf('+ -'), 2, opAssoc.LEFT), ]) arith_expr.runTests(''' 5+3*6 (5+3)*6 -2--11 ''', fullDump=False) prints:: 5+3*6 [[5, '+', [3, '*', 6]]] (5+3)*6 [[[5, '+', 3], '*', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] c @ s e Zd Zddd�ZdS )zinfixNotation.<locals>._FBTc S s | j �||� |g fS r� )r� r� r� r r r r� � s z$infixNotation.<locals>._FB.parseImplN)Tr� r r r r �_FB� s rj r� Nr� r� z%s termz %s%s termr� z@if numterms=3, opExpr must be a tuple or list of two expressionsr� z6operator must be unary (1), binary (2), or ternary (3)z2operator must indicate right or left associativity)r, r- r� r� rA r� rt �LEFTr/ r8 �RIGHTr� r: r� r@ r r� )ZbaseExprZopListZlparZrparrj r� ZlastExprr� ZoperDefZopExprZarityZrightLeftAssocr� ZtermNameZopExpr1ZopExpr2ZthisExprrE r r r r� d s` H� & � & � r� z4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�"z string enclosed in double quotesz4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*�'z string enclosed in single quotesz*quotedString using single or double quotes�uzunicode string literalc C s� | |krt d��|du �r*t| t��r"t|t��r"t| �dkr�t|�dkr�|dur�tt| t| | tj dd� ��� dd� �}n$t � � t| | tj �� dd� � }nx|dur�tt| t | � t |� ttjdd� ��� dd� �}n4ttt | � t |� ttjdd� ��� d d� �}nt d ��t � }|du�rd|tt| �t||B |B � t|� �K }n$|tt| �t||B � t|� �K }|�d | |f � |S ) a� Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default). Parameters: - opener - opening character for a nested list (default= ``"("``); can also be a pyparsing expression - closer - closing character for a nested list (default= ``")"``); can also be a pyparsing expression - content - expression for items within the nested lists (default= ``None``) - ignoreExpr - expression for ignoring opening and closing delimiters (default= :class:`quotedString`) If an expression is not provided for the content argument, the nested expression will capture all whitespace-delimited content between delimiters as a list of separate values. Use the ``ignoreExpr`` argument to define expressions that may contain opening or closing characters that should not be treated as opening or closing characters for nesting, such as quotedString or a comment expression. Specify multiple expressions using an :class:`Or` or :class:`MatchFirst`. The default is :class:`quotedString`, but if no expressions are to be ignored, then pass ``None`` for this argument.

It is the recommended replacement 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 3.8 removed it altogether. Its predecessor function :py:func:`platform.dist` was already deprecated since Python 2.6 and removed in Python 3.8. Still, there are many cases in which access to OS distribution information is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for more information. � Nz1.6.0Z UNIXCONFDIRz/etcZ UNIXUSRLIBDIRz/usr/libz os-releaseZolZoracleZrhel)ZenterpriseenterpriseasZenterpriseenterpriseserverZredhatenterpriseworkstationZredhatenterpriseserverZredhatenterprisecomputenodeZredhatzA(?:[^)]*\)(.*)\()? *(?:STL )?([\d.+\-a-z]*\d) *(?:esaeler *)?(.+)z(\w+)[-_](release|version)$Zdebian_versionz lsb-releasez oem-releasezsystem-releasez plesk-releaseziredmail-releaseTc C s t jdtdd� t�| �S )aG .. deprecated:: 1.6.0 :func:`distro.linux_distribution()` is deprecated. It should only be used as a compatibility shim with Python's :py:func:`platform.linux_distribution()`. Please use :func:`distro.id`, :func:`distro.version` and :func:`distro.name` instead. Return information about the current OS 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 OS 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 OS distributions. z�distro.linux_distribution() is deprecated.

For a number of OS 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 "openbsd" OpenBSD "netbsd" NetBSD "freebsd" FreeBSD "midnightbsd" MidnightBSD ============== ========================================= 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 OS 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 Mr Fc C s t �| �S )ak Return the name of the current OS 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 �| |�S )av Return the version of the current OS 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 �| �S )a� Return the version of the current OS 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`.

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 � s r c C s t �| |�S )a� Return certain machine-readable information items about the current OS 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`.

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 OS 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.

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. * ``include_uname`` (bool): Controls whether uname command output is included as a data source. If the uname command is not available in the program execution path the data source for the uname command will be empty. * ``root_dir`` (string): The absolute path to the root directory to use to find distro-related information files. 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. * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter. This controls whether the lsb information will be loaded. * ``include_uname`` (bool): The result of the ``include_uname`` parameter. This controls whether the uname information will be loaded. 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. �etczusr/libr6 N)�root_dir�os�path�join� _UNIXCONFDIR�etc_dir�_UNIXUSRLIBDIRZ usr_lib_dir�os_release_file�_OS_RELEASE_BASENAME�isfile�distro_release_file� include_lsb� include_uname)r) rC r? rB rD r8 Zetc_dir_os_release_fileZusr_lib_os_release_filer r r r+ � s$ O��� zLinuxDistribution.__init__c C s dj | d�S )zReturn repr of all infoae LinuxDistribution(os_release_file={self.os_release_file!r}, distro_release_file={self.distro_release_file!r}, include_lsb={self.include_lsb!r}, include_uname={self.include_uname!r}, _os_release_info={self._os_release_info!r}, _lsb_release_info={self._lsb_release_info!r}, _distro_release_info={self._distro_release_info!r}, _uname_info={self._uname_info!r})�r) )r, rE r r r �__repr__� s ��zLinuxDistribution.__repr__c C s" |r | � � n| �� | �� | �� fS )z� Return information about the OS distribution that is compatible with Python's :func:`platform.linux_distribution`, supporting a subset of its parameters.

Example usage:: from pip._vendor.urllib3 import PoolManager from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox if is_appengine_sandbox(): # AppEngineManager uses AppEngine's URLFetch API behind the scenes http = AppEngineManager() else: # PoolManager uses a socket-level API behind the scenes http = PoolManager() r = http.request('GET', 'https://google.com/') There are `limitations <https://cloud.google.com/appengine/docs/python/urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be the best choice for your application. There are three options for using urllib3 on Google App Engine: 1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is cost-effective in many circumstances as long as your usage is within the limitations. 2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets. Sockets also have `limitations and restrictions <https://cloud.google.com/appengine/docs/python/sockets/ #limitations-and-restrictions>`_ and have a lower free quota than URLFetch. To use sockets, be sure to specify the following in your ``app.yaml``:: env_variables: GAE_USE_SOCKETS_HTTPLIB : 'true' 3. If you are using `App Engine Flexible <https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard :class:`PoolManager` without any configuration or special environment variables. � )�absolute_importN� )� HTTPError� HTTPWarning� MaxRetryError� ProtocolError�SSLError� TimeoutError)�urljoin)�RequestMethods)� HTTPResponse)�Retry)�Timeout� )�_appengine_environ)�urlfetchc @ s e Zd ZdS )�AppEnginePlatformWarningN��__name__� __module__� __qualname__� r r �I/usr/lib/python3.9/site-packages/pip/_vendor/urllib3/contrib/appengine.pyr G s r c @ s e Zd ZdS )�AppEnginePlatformErrorNr r r r r r K s r c @ sX e Zd ZdZddd�Zdd� Zdd � Zddddejfd d �Z d d � Z dd� Z dd� Z dS )�AppEngineManagera Connection manager for Google App Engine sandbox applications. This manager uses the URLFetch service directly instead of using the emulated httplib, and is subject to URLFetch limitations as described in the App Engine documentation `here <https://cloud.google.com/appengine/docs/python/urlfetch>`_. Notably it will raise an :class:`AppEnginePlatformError` if: * URLFetch is not available. * If you attempt to use this on App Engine Flexible, as full socket support is available. * If a request size is more than 10 megabytes. * If a response size is more than 32 megabytes. * If you use an unsupported request method such as OPTIONS.

Follow these instructions if you would like to verify TLS certificates in Python 2. Note, the default libraries do *not* do certificate checking; you need to do additional work to validate certificates yourself. This needs the following packages installed: * `pyOpenSSL`_ (tested with 16.0.0) * `cryptography`_ (minimum 1.3.4, from pyopenssl) * `idna`_ (minimum 2.0, from cryptography) However, pyopenssl depends on cryptography, which depends on idna, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: .. code-block:: bash $ python -m pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this: .. code-block:: python try: import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl pyopenssl.inject_into_urllib3() except ImportError: pass Now you can use :mod:`urllib3` as you normally would, and it will support SNI when the required modules are installed. Activating this module also has the positive side effect of disabling SSL/TLS compression in Python 2 (see `CRIME attack`_). .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) .. _pyopenssl: https://www.pyopenssl.org .. _cryptography: https://cryptography.io .. _idna: https://github.com/kjd/idna � )�absolute_importN)�x509)�backend)� _Certificate)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �I/usr/lib/python3.9/site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pyr ; s r )�BytesIO)�error)�timeout)� _fileobject� )�backport_makefile)�util)�six)�PROTOCOL_TLS_CLIENT�inject_into_urllib3�extract_from_urllib3T�PROTOCOL_SSLv3� SSLv3_METHOD�PROTOCOL_TLSv1_1�TLSv1_1_METHOD�PROTOCOL_TLSv1_2�TLSv1_2_METHODc c s | ]\}}||fV qd S �Nr )�.0�k�vr r r � <genexpr>m � r! i @ c C s4 t � tt_ttj_tt_ttj_dt_dtj_dS )z7Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.TN)�_validate_dependencies_met�PyOpenSSLContextr � SSLContext�ssl_�HAS_SNI� IS_PYOPENSSLr r r r r y s c C s. t t_t tj_tt_ttj_dt_dtj_dS )z4Undo monkey-patching by :func:`inject_into_urllib3`.FN)�orig_util_SSLContextr r% r& �orig_util_HAS_SNIr' r( r r r r r � s c C sR ddl m} t| dd�du r$td��ddlm} |� }t|dd�du rNtd��dS ) z{ Verifies that PyOpenSSL's package-level dependencies have been met.

Cryptography produces a dNSName as a unicode string that was idna-decoded from ASCII bytes. We need to idna-encode that string to get it back, and then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and SOCKS5. To enable its functionality, either install PySocks or install this module with the ``socks`` extra. The SOCKS implementation supports the full range of urllib3 features. It also supports the following SOCKS features: - SOCKS4A (``proxy_url='socks4a://...``) - SOCKS4 (``proxy_url='socks4://...``) - SOCKS5 with remote DNS (``proxy_url='socks5h://...``) - SOCKS5 with local DNS (``proxy_url='socks5://...``) - Usernames and passwords for the SOCKS proxy .. note:: It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in your ``proxy_url`` to ensure that DNS resolution is done from the remote server instead of client-side when connecting to a domain name. SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5 supports IPv4, IPv6, and domain names.

This makes platform-native TLS available to urllib3 users on macOS without the use of a compiler. This is an important feature because the Python Package Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL that ships with macOS is not capable of doing TLSv1.2. The only way to resolve this is to give macOS users an alternative solution to the problem, and that solution is to use SecureTransport. We use ctypes here because this solution must not require a compiler. That's because pip is not allowed to require a compiler either. This is not intended to be a seriously long-term solution to this problem. The hope is that PEP 543 will eventually solve this issue for us, at which point we can retire this contrib module. But in the short term, we need to solve the impending tire fire that is Python on Mac without this kind of contrib module. So...here we are. To use this module, simply import and inject it:: import pip._vendor.urllib3.contrib.securetransport as securetransport securetransport.inject_into_urllib3() Happy TLSing!

For that reason, this code should be considered to be covered both by urllib3's license and by oscrypto's: .. code-block:: Copyright (c) 2015-2016 Will Bond <will@wbond.net> Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

URLFetch is cost-effective in many circumstances as long as your usage is within the limitations. 2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets. Sockets also have `limitations and restrictions <https://cloud.google.com/appengine/docs/python/sockets/ #limitations-and-restrictions>`_ and have a lower free quota than URLFetch. To use sockets, be sure to specify the following in your ``app.yaml``:: env_variables: GAE_USE_SOCKETS_HTTPLIB : 'true' 3. If you are using `App Engine Flexible <https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard :class:`PoolManager` without any configuration or special environment variables. � )�absolute_importN� )� HTTPError� HTTPWarning� MaxRetryError� ProtocolError�SSLError� TimeoutError)�urljoin)�RequestMethods)� HTTPResponse)�Retry)�Timeout� )�_appengine_environ)�urlfetchc @ s e Zd ZdS )�AppEnginePlatformWarningN��__name__� __module__� __qualname__� r r �I/usr/lib/python3.9/site-packages/pip/_vendor/urllib3/contrib/appengine.pyr G s r c @ s e Zd ZdS )�AppEnginePlatformErrorNr r r r r r K s r c @ sX e Zd ZdZddd�Zdd� Zdd � Zddddejfd d �Z d d � Z dd� Z dd� Z dS )�AppEngineManagera Connection manager for Google App Engine sandbox applications.

Notably it will raise an :class:`AppEnginePlatformError` if: * URLFetch is not available. * If you attempt to use this on App Engine Flexible, as full socket support is available. * If a request size is more than 10 megabytes. * If a response size is more than 32 megabytes. * If you use an unsupported request method such as OPTIONS.

Follow these instructions if you would like to verify TLS certificates in Python 2. Note, the default libraries do *not* do certificate checking; you need to do additional work to validate certificates yourself. This needs the following packages installed: * `pyOpenSSL`_ (tested with 16.0.0) * `cryptography`_ (minimum 1.3.4, from pyopenssl) * `idna`_ (minimum 2.0, from cryptography) However, pyopenssl depends on cryptography, which depends on idna, so while we use all three directly here we end up having relatively few packages required. You can install them with the following command: .. code-block:: bash $ python -m pip install pyopenssl cryptography idna To activate certificate checking, call :func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code before you begin making HTTP requests. This can be done in a ``sitecustomize`` module, or at any other time before your application begins using ``urllib3``, like this: .. code-block:: python try: import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl pyopenssl.inject_into_urllib3() except ImportError: pass Now you can use :mod:`urllib3` as you normally would, and it will support SNI when the required modules are installed. Activating this module also has the positive side effect of disabling SSL/TLS compression in Python 2 (see `CRIME attack`_). .. _sni: https://en.wikipedia.org/wiki/Server_Name_Indication .. _crime attack: https://en.wikipedia.org/wiki/CRIME_(security_exploit) .. _pyopenssl: https://www.pyopenssl.org .. _cryptography: https://cryptography.io .. _idna: https://github.com/kjd/idna � )�absolute_importN)�x509)�backend)� _Certificate)�UnsupportedExtensionc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �I/usr/lib/python3.9/site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pyr ; s r )�BytesIO)�error)�timeout)� _fileobject� )�backport_makefile)�util)�six)�PROTOCOL_TLS_CLIENT�inject_into_urllib3�extract_from_urllib3T�PROTOCOL_SSLv3� SSLv3_METHOD�PROTOCOL_TLSv1_1�TLSv1_1_METHOD�PROTOCOL_TLSv1_2�TLSv1_2_METHODc c s | ]\}}||fV qd S �Nr )�.0�k�vr r r � <genexpr>m � r! i @ c C s4 t � tt_ttj_tt_ttj_dt_dtj_dS )z7Monkey-patch urllib3 with PyOpenSSL-backed SSL-support.TN)�_validate_dependencies_met�PyOpenSSLContextr � SSLContext�ssl_�HAS_SNI� IS_PYOPENSSLr r r r r y s c C s. t t_t tj_tt_ttj_dt_dtj_dS )z4Undo monkey-patching by :func:`inject_into_urllib3`.FN)�orig_util_SSLContextr r% r& �orig_util_HAS_SNIr' r( r r r r r � s c C sR ddl m} t| dd�du r$td��ddlm} |� }t|dd�du rNtd��dS ) z{ Verifies that PyOpenSSL's package-level dependencies have been met.

Cryptography produces a dNSName as a unicode string that was idna-decoded from ASCII bytes. We need to idna-encode that string to get it back, and then on Python 3 we also need to convert to unicode via UTF-8 (the stdlib uses PyUnicode_FromStringAndSize on it, which decodes via UTF-8).

This makes platform-native TLS available to urllib3 users on macOS without the use of a compiler. This is an important feature because the Python Package Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL that ships with macOS is not capable of doing TLSv1.2. The only way to resolve this is to give macOS users an alternative solution to the problem, and that solution is to use SecureTransport. We use ctypes here because this solution must not require a compiler. That's because pip is not allowed to require a compiler either. This is not intended to be a seriously long-term solution to this problem. The hope is that PEP 543 will eventually solve this issue for us, at which point we can retire this contrib module. But in the short term, we need to solve the impending tire fire that is Python on Mac without this kind of contrib module. So...here we are. To use this module, simply import and inject it:: import pip._vendor.urllib3.contrib.securetransport as securetransport securetransport.inject_into_urllib3() Happy TLSing! This code is a bastardised version of the code found in Will Bond's oscrypto library. An enormous debt is owed to him for blazing this trail for us. For that reason, this code should be considered to be covered both by urllib3's license and by oscrypto's: .. code-block:: Copyright (c) 2015-2016 Will Bond <will@wbond.net> Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and SOCKS5. To enable its functionality, either install PySocks or install this module with the ``socks`` extra. The SOCKS implementation supports the full range of urllib3 features. It also supports the following SOCKS features: - SOCKS4A (``proxy_url='socks4a://...``) - SOCKS4 (``proxy_url='socks4://...``) - SOCKS5 with remote DNS (``proxy_url='socks5h://...``) - SOCKS5 with local DNS (``proxy_url='socks5://...``) - Usernames and passwords for the SOCKS proxy .. note:: It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in your ``proxy_url`` to ensure that DNS resolution is done from the remote server instead of client-side when connecting to a domain name. SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5 supports IPv4, IPv6, and domain names. When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url`` will be sent as the ``userid`` section of the SOCKS request: .. code-block:: python proxy_url="socks4a://<userid>@proxy-host" When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion of the ``proxy_url`` will be sent as the username/password to authenticate with the proxy: .. code-block:: python proxy_url="socks5h://<username>:<password>@proxy-host" � )�absolute_importN� )�DependencyWarningz�SOCKS support in urllib3 requires the installation of optional dependencies: specifically, PySocks.

The goal here is to provide the low-level API to SecureTransport. These are essentially the C-level functions and constants, and they're pretty gross to work with.

SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5 supports IPv4, IPv6, and domain names.

Backwards-compatible with :class:`http.client.HTTPResponse` but the response ``body`` is loaded and decoded on-demand when the ``data`` property is accessed. This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in :class:`http.client.HTTPResponse`: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param original_response: When this HTTPResponse wrapper is generated from an :class:`http.client.HTTPResponse` object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present.

Additional keyword parameters are used to configure attributes of the connection. Accepted parameters include: - ``strict``: See the documentation on :class:`urllib3.connectionpool.HTTPConnectionPool` - ``source_address``: Set the source address for the current connection. - ``socket_options``: Set specific options on the underlying socket. If not specified, then defaults are loaded from ``HTTPConnection.default_socket_options`` which includes disabling Nagle's algorithm (sets TCP_NODELAY to 1) unless the connection is behind a proxy. For example, if you wish to enable TCP Keep Alive in addition to the defaults, you might pass: .. code-block:: python HTTPConnection.default_socket_options + [ (socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1), ] Or you may want to disable the defaults by passing an empty list (e.g., ``[]``). r& r FNc O sf t js|�dd � |�d�| _|�d| j�| _|�dd �| _|�dd �| _t j | g|�R i |�� d S )N�strict�source_address�socket_options�proxy� proxy_config) r ZPY2�pop�getr* �default_socket_optionsr+ r, r- �_HTTPConnection�__init__)�self�args�kwr r r r2 s s zHTTPConnection.__init__c C s | j �d�S )a� Getter method to remove any trailing dots that indicate the hostname is an FQDN. In general, SSL certificates don't include the trailing dot indicating a fully-qualified domain name, and thus, they don't validate properly when checked against a domain name that includes the dot. In addition, some servers may not expect to receive the trailing dot when provided. However, the hostname with trailing dot is critical to DNS resolution; doing a lookup with the trailing dot will properly only resolve the appropriate FQDN, whereas a lookup without a trailing dot will search the system's search domain list. Thus, it's important to keep the original host around for use only in those cases where it's appropriate (i.e., when doing DNS lookup to establish the actual TCP connection across which we're going to send HTTP requests). �.)� _dns_host�rstrip�r3 r r r �host� s zHTTPConnection.hostc C s || _ dS )z� Setter for the `host` property.

Provides behavior for making common types of HTTP request methods and decides which type of request field encoding to use. Specifically, :meth:`.request_encode_url` is for sending requests whose fields are encoded in the URL (such as GET, HEAD, DELETE). :meth:`.request_encode_body` is for sending requests whose fields are encoded in the *body* of the request using multipart or www-form-urlencoded (such as for POST, PUT, PATCH). :meth:`.request` is for making any kind of request, it will look up the appropriate encoding format and use one of the above two methods to make the request.

This is a convenience method that requires the least amount of manual effort.

This is useful for request methods like POST, PUT, PATCH, etc. When ``encode_multipart=True`` (default), then :func:`urllib3.encode_multipart_formdata` is used to encode the payload with the appropriate content type. Otherwise :func:`urllib.parse.urlencode` is used with the 'application/x-www-form-urlencoded' content type. Multipart encoding must be used when posting files, and it's reasonably safe to use it in other times too. However, it may break request signing, such as with OAuth. Supports an optional ``fields`` parameter of key/value strings AND key/filetuple. A filetuple is a (filename, data, MIME type) tuple where the MIME type is optional. For example:: fields = { 'foo': 'bar', 'fakefile': ('foofile.txt', 'contents of foofile'), 'realfile': ('barfile.txt', open('realfile').read()), 'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'), 'nonamefile': 'contents of nonamefile field', } When uploading a file, providing a filename (the first parameter of the tuple) is optional but recommended to best mimic behavior of browsers. Note that if ``headers`` are supplied, the 'Content-Type' header will be overwritten because it depends on the dynamic random boundary string which is used to compose the body of the request. The random boundary string can be explicitly set with the ``multipart_boundary`` parameter.

Additional keyword parameters are used to configure attributes of the connection. Accepted parameters include: - ``strict``: See the documentation on :class:`urllib3.connectionpool.HTTPConnectionPool` - ``source_address``: Set the source address for the current connection. - ``socket_options``: Set specific options on the underlying socket. If not specified, then defaults are loaded from ``HTTPConnection.default_socket_options`` which includes disabling Nagle's algorithm (sets TCP_NODELAY to 1) unless the connection is behind a proxy. For example, if you wish to enable TCP Keep Alive in addition to the defaults, you might pass: .. code-block:: python HTTPConnection.default_socket_options + [ (socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1), ] Or you may want to disable the defaults by passing an empty list (e.g., ``[]``). r& r FNc O sf t js|�dd � |�d�| _|�d| j�| _|�dd �| _|�dd �| _t j | g|�R i |�� d S )N�strict�source_address�socket_options�proxy� proxy_config) r ZPY2�pop�getr* �default_socket_optionsr+ r, r- �_HTTPConnection�__init__)�self�args�kwr r r r2 s s zHTTPConnection.__init__c C s | j �d�S )a� Getter method to remove any trailing dots that indicate the hostname is an FQDN. In general, SSL certificates don't include the trailing dot indicating a fully-qualified domain name, and thus, they don't validate properly when checked against a domain name that includes the dot. In addition, some servers may not expect to receive the trailing dot when provided. However, the hostname with trailing dot is critical to DNS resolution; doing a lookup with the trailing dot will properly only resolve the appropriate FQDN, whereas a lookup without a trailing dot will search the system's search domain list. Thus, it's important to keep the original host around for use only in those cases where it's appropriate (i.e., when doing DNS lookup to establish the actual TCP connection across which we're going to send HTTP requests). �.)� _dns_host�rstrip�r3 r r r �host� s zHTTPConnection.hostc C s || _ dS )z� Setter for the `host` property.

Must not contain multiple field names when compared case-insensitively. :param kwargs: Additional field-value pairs to pass in to ``dict.update``. A ``dict`` like container for storing HTTP Headers. Field names are stored and compared case-insensitively in compliance with RFC 7230. Iteration provides the first case-sensitive key seen for each case-insensitive pair. Using ``__setitem__`` syntax overwrites fields that compare equal case-insensitively in order to maintain ``dict``'s api. For fields that compare equal, instead create a new ``HTTPHeaderDict`` and use ``.add`` in a loop. If multiple fields that are equal case-insensitively are passed to the constructor or ``.update``, the behavior is undefined and some will be lost. >>> headers = HTTPHeaderDict() >>> headers.add('Set-Cookie', 'foo=bar') >>> headers.add('set-cookie', 'baz=quxx') >>> headers['content-length'] = '7' >>> headers['SET-cookie'] 'foo=bar, baz=quxx' >>> headers['Content-Length'] '7' Nc sP t t| ��� t� | _|d ur>t|t�r4| �|� n | �|� |rL| �|� d S r )�superr r" r r � isinstance� _copy_from�extend)r �headers�kwargs�� __class__r r r" � s zHTTPHeaderDict.__init__c C s ||g| j |�� < | j |�� S r �r �lower�r r$ �valr r r r, � s zHTTPHeaderDict.__setitem__c C s | j |�� }d�|dd � �S )N�, r �r r? �joinr@ r r r r& � s zHTTPHeaderDict.__getitem__c C s | j |�� = d S r r> �r r$ r r r r- � s zHTTPHeaderDict.__delitem__c C s |� � | jv S r )r? r rE r r r � __contains__� s zHTTPHeaderDict.__contains__c C s^ t |t�st|d�sdS t |t| ��s2t| �|�}tdd� | �� D ��tdd� |�� D ��kS )Nr4 Fc s s | ]\}}|� � |fV qd S r )r? )�.0�k�vr r r � <genexpr>� � z(HTTPHeaderDict.__eq__.<locals>.<genexpr>)r7 r �hasattr�type�dict� itermerged�r �otherr r r �__eq__� s �zHTTPHeaderDict.__eq__c C s | � |� S r )rR rP r r r �__ne__� s zHTTPHeaderDict.__ne__c C s t | j�S r )r) r r r r r r. � s zHTTPHeaderDict.__len__c c s | j �� D ]}|d V q d S )Nr )r r3 )r �valsr r r r0 � s zHTTPHeaderDict.__iter__c C s> z | | }W n" t y. || ju r&� | Y S 0 | |= |S dS )z�D.pop(k[,d]) -> v, remove specified key and return the corresponding value.

This parameter is ignored in Python 3. :param timeout: Socket timeout in seconds for each individual connection. This can be a float or integer, which sets the timeout for the HTTP request, or an instance of :class:`urllib3.util.Timeout` which gives you more fine-grained control over request timeouts. After the constructor has been parsed, this is always a `urllib3.util.Timeout` object. :param maxsize: Number of connections to save that can be reused. More than 1 is useful in multithreaded situations. If ``block`` is set to False, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param retries: Retry configuration to use by default with requests in this pool. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. �httpNFr c K s� t �| ||� t�| |� || _t|t�s4t�|�}|d u rBtj}|| _ || _ | � |�| _ || _ | | _| pli | _| | _t|�D ]} | j �d � q~d| _d| _| | _| jr�| j�dg � | j| jd< | j| jd< d S )Nr Zsocket_options�proxy� proxy_config)r- r7 r �strict� isinstancer' � from_floatr& ZDEFAULTr �retriesrE �pool�blockrH � proxy_headersrI �xrange�put�num_connections� num_requests�conn_kw� setdefault)r4 r0 r3 rJ r �maxsizerO �headersrM �_proxy�_proxy_headersZ _proxy_configrU �_r5 r5 r6 r7 � s. zHTTPConnectionPool.__init__c C sR | j d7 _ t�d| j | j| jp$d� | jf | j| j| jj| jd�| j ��}|S )z9 Return a fresh :class:`HTTPConnection`. r z(Starting new HTTP connection (%d): %s:%sZ80)r0 r3 r rJ ) rS �log�debugr0 r3 � ConnectionClsr �connect_timeoutrJ rU �r4 �connr5 r5 r6 � _new_conn� s ���z HTTPConnectionPool._new_connc C s� d}z| j j| j|d�}W n> ty6 t| d��Y n$ tjyX | jrTt| d��Y n0 |r�t|�r�t � d| j � |� � t |dd�dkr�d}|p�| �� S ) a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param url: The URL to perform the request on. :param body: Data to send in the request body, either :class:`str`, :class:`bytes`, an iterable of :class:`str`/:class:`bytes`, or a file-like object. :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. Pass ``None`` to retry until you receive a response. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry. If ``False``, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned. :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When ``False``, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``response_kw.get('preload_content', True)``. :param chunked: If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False. :param int body_pos: Position to seek to in file-like body in the event of a retry or redirect. Typically this won't need to be set because urllib3 will auto-populate the value when needed. :param \**response_kw: Additional parameters are passed to :meth:`urllib3.response.HTTPResponse.from_httplib` N)�redirect�defaultZpreload_contentTr� Fr rz )r �bodyrX r� Zrequest_method)rN � connectionrM zCannot connect to proxy.zConnection aborted.� )r �_poolZ _stacktracez1Retrying (%r) after connection broken by '%r': %s)r � pool_timeout� release_connr� �body_posi/ ZGET)�responser� zRedirecting %s -> %s)rM r� �assert_same_hostr r� r� r� r� z Retry-Afterz Retry: %s)=r, r/ rX rK r& Zfrom_intrM rc r� r r� r Z ensure_strr) rw r" rH rI �copy�updaterP r$ ro rg r_ r rf rm r� � ResponseClsZ from_httplibr r r r� r r r r r r Z increment�sysr| �sleepr> rj r\ ri �urlopenZget_redirect_locationr� r Zraise_on_redirectZ drain_connZsleep_for_retryr] �boolZ getheaderZis_retryZraise_on_status) r4 r� rw r� rX rM r� r� r r� r� r� r� Z response_kwZ parsed_urlZdestination_schemera Zrelease_this_connZhttp_tunnel_requiredrv Z clean_exitr� Zis_new_proxy_connr� Z response_connr� r� Zredirect_locationZhas_retry_afterr5 r5 r6 r� sV m � � ���� � � � ��� � �� � �� �zHTTPConnectionPool.urlopen)N)r9 rB rC rD r/ r r^ r r� r' r� r7 rb rg rj rl rm ro ry rn r� r� r> r� r� r5 r5 r5 r6 rF h sL ;� 6 ' � w�rF c sp e Zd ZdZdZeZddejdddddddddddddddfdd�Z dd � Z d d � Z d d � Z � fdd�Z � ZS )�HTTPSConnectionPoola Same as :class:`.HTTPConnectionPool`, but HTTPS. :class:`.HTTPSConnection` uses one of ``assert_fingerprint``, ``assert_hostname`` and ``host`` in this order to verify connections.

Must not contain multiple field names when compared case-insensitively. :param kwargs: Additional field-value pairs to pass in to ``dict.update``. A ``dict`` like container for storing HTTP Headers. Field names are stored and compared case-insensitively in compliance with RFC 7230. Iteration provides the first case-sensitive key seen for each case-insensitive pair. Using ``__setitem__`` syntax overwrites fields that compare equal case-insensitively in order to maintain ``dict``'s api. For fields that compare equal, instead create a new ``HTTPHeaderDict`` and use ``.add`` in a loop. If multiple fields that are equal case-insensitively are passed to the constructor or ``.update``, the behavior is undefined and some will be lost. >>> headers = HTTPHeaderDict() >>> headers.add('Set-Cookie', 'foo=bar') >>> headers.add('set-cookie', 'baz=quxx') >>> headers['content-length'] = '7' >>> headers['SET-cookie'] 'foo=bar, baz=quxx' >>> headers['Content-Length'] '7' Nc sP t t| ��� t� | _|d ur>t|t�r4| �|� n | �|� |rL| �|� d S r )�superr r" r r � isinstance� _copy_from�extend)r �headers�kwargs�� __class__r r r" � s zHTTPHeaderDict.__init__c C s ||g| j |�� < | j |�� S r �r �lower�r r$ �valr r r r, � s zHTTPHeaderDict.__setitem__c C s | j |�� }d�|dd � �S )N�, r �r r? �joinr@ r r r r& � s zHTTPHeaderDict.__getitem__c C s | j |�� = d S r r> �r r$ r r r r- � s zHTTPHeaderDict.__delitem__c C s |� � | jv S r )r? r rE r r r � __contains__� s zHTTPHeaderDict.__contains__c C s^ t |t�st|d�sdS t |t| ��s2t| �|�}tdd� | �� D ��tdd� |�� D ��kS )Nr4 Fc s s | ]\}}|� � |fV qd S r )r? )�.0�k�vr r r � <genexpr>� � z(HTTPHeaderDict.__eq__.<locals>.<genexpr>)r7 r �hasattr�type�dict� itermerged�r �otherr r r �__eq__� s �zHTTPHeaderDict.__eq__c C s | � |� S r )rR rP r r r �__ne__� s zHTTPHeaderDict.__ne__c C s t | j�S r )r) r r r r r r. � s zHTTPHeaderDict.__len__c c s | j �� D ]}|d V q d S )Nr )r r3 )r �valsr r r r0 � s zHTTPHeaderDict.__iter__c C s> z | | }W n" t y. || ju r&� | Y S 0 | |= |S dS )z�D.pop(k[,d]) -> v, remove specified key and return the corresponding value.

This parameter is ignored in Python 3. :param timeout: Socket timeout in seconds for each individual connection. This can be a float or integer, which sets the timeout for the HTTP request, or an instance of :class:`urllib3.util.Timeout` which gives you more fine-grained control over request timeouts. After the constructor has been parsed, this is always a `urllib3.util.Timeout` object. :param maxsize: Number of connections to save that can be reused. More than 1 is useful in multithreaded situations. If ``block`` is set to False, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param retries: Retry configuration to use by default with requests in this pool. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. �httpNFr c K s� t �| ||� t�| |� || _t|t�s4t�|�}|d u rBtj}|| _ || _ | � |�| _ || _ | | _| pli | _| | _t|�D ]} | j �d � q~d| _d| _| | _| jr�| j�dg � | j| jd< | j| jd< d S )Nr Zsocket_options�proxy� proxy_config)r- r7 r �strict� isinstancer' � from_floatr& ZDEFAULTr �retriesrE �pool�blockrH � proxy_headersrI �xrange�put�num_connections� num_requests�conn_kw� setdefault)r4 r0 r3 rJ r �maxsizerO �headersrM �_proxy�_proxy_headersZ _proxy_configrU �_r5 r5 r6 r7 � s. zHTTPConnectionPool.__init__c C sR | j d7 _ t�d| j | j| jp$d� | jf | j| j| jj| jd�| j ��}|S )z9 Return a fresh :class:`HTTPConnection`. r z(Starting new HTTP connection (%d): %s:%sZ80)r0 r3 r rJ ) rS �log�debugr0 r3 � ConnectionClsr �connect_timeoutrJ rU �r4 �connr5 r5 r6 � _new_conn� s ���z HTTPConnectionPool._new_connc C s� d}z| j j| j|d�}W n> ty6 t| d��Y n$ tjyX | jrTt| d��Y n0 |r�t|�r�t � d| j � |� � t |dd�dkr�d}|p�| �� S ) a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param url: The URL to perform the request on. :param body: Data to send in the request body, either :class:`str`, :class:`bytes`, an iterable of :class:`str`/:class:`bytes`, or a file-like object. :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. Pass ``None`` to retry until you receive a response. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry. If ``False``, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned. :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When ``False``, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool.

This class is also compatible with the Python standard library's :mod:`io` module, and can hence be treated as a readable object in the context of that framework. Extra parameters for behaviour not present in :class:`http.client.HTTPResponse`: :param preload_content: If True, the response's body will be preloaded during construction. :param decode_content: If True, will attempt to decode the body based on the 'content-encoding' header. :param original_response: When this HTTPResponse wrapper is generated from an :class:`http.client.HTTPResponse` object, it's convenient to include the original for debug purposes. It's otherwise unused. :param retries: The retries contains the last :class:`~urllib3.util.retry.Retry` that was used during the request. :param enforce_content_length: Enforce content length checking. Body returned by server must match value of Content-Length header, if present.

Provides behavior for making common types of HTTP request methods and decides which type of request field encoding to use. Specifically, :meth:`.request_encode_url` is for sending requests whose fields are encoded in the URL (such as GET, HEAD, DELETE). :meth:`.request_encode_body` is for sending requests whose fields are encoded in the *body* of the request using multipart or www-form-urlencoded (such as for POST, PUT, PATCH). :meth:`.request` is for making any kind of request, it will look up the appropriate encoding format and use one of the above two methods to make the request.

This is a convenience method that requires the least amount of manual effort. It can be used in most situations, while still having the option to drop down to more specific methods when necessary, such as :meth:`request_encode_url`, :meth:`request_encode_body`, or even the lowest level :meth:`urlopen`.

This is useful for request methods like POST, PUT, PATCH, etc. When ``encode_multipart=True`` (default), then :func:`urllib3.encode_multipart_formdata` is used to encode the payload with the appropriate content type. Otherwise :func:`urllib.parse.urlencode` is used with the 'application/x-www-form-urlencoded' content type. Multipart encoding must be used when posting files, and it's reasonably safe to use it in other times too. However, it may break request signing, such as with OAuth. Supports an optional ``fields`` parameter of key/value strings AND key/filetuple. A filetuple is a (filename, data, MIME type) tuple where the MIME type is optional. For example:: fields = { 'foo': 'bar', 'fakefile': ('foofile.txt', 'contents of foofile'), 'realfile': ('barfile.txt', open('realfile').read()), 'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'), 'nonamefile': 'contents of nonamefile field', } When uploading a file, providing a filename (the first parameter of the tuple) is optional but recommended to best mimic behavior of browsers. Note that if ``headers`` are supplied, the 'Content-Type' header will be overwritten because it depends on the dynamic random boundary string which is used to compose the body of the request. The random boundary string can be explicitly set with the ``multipart_boundary`` parameter. Nr r zFrequest got values for both 'fields' and 'body', can only specify one.)�boundaryz!application/x-www-form-urlencodedz Content-Type)r � TypeErrorr r r r ) r r r r r r r r r r Z content_typer r r r b s( -�� � z"RequestMethods.request_encode_body)N)NNTN)NN)NN)NNTN) �__name__� __module__� __qualname__�__doc__r r r r r r r r r r r s � �N) Z __future__r Zfilepostr Z packages.six.moves.urllib.parser �__all__�objectr r r r r �<module> s PK �n�Z����� � _vendor/urllib3/filepost.pynu �[��� from __future__ import absolute_import import binascii import codecs import os from io import BytesIO from .fields import RequestField from .packages import six from .packages.six import b writer = codecs.lookup("utf-8")[3] def choose_boundary(): """ Our embarrassingly-simple replacement for mimetools.choose_boundary.

Timeouts can be defined as a default for a pool: .. code-block:: python timeout = Timeout(connect=2.0, read=7.0) http = PoolManager(timeout=timeout) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool): .. code-block:: python response = http.request('GET', 'http://example.com/', timeout=Timeout(10)) Timeouts can be disabled by setting all the parameters to ``None``: .. code-block:: python no_timeout = Timeout(connect=None, read=None) response = http.request('GET', 'http://example.com/, timeout=no_timeout) :param total: This combines the connect and read timeouts into one; the read timeout will be set to the time leftover from the connect attempt. In the event that both a connect timeout and a total are specified, or a read timeout and a total are specified, the shorter timeout will be applied. Defaults to None. :type total: int, float, or None :param connect: The maximum amount of time (in seconds) to wait for a connection attempt to a server to succeed. Omitting the parameter will default the connect timeout to the system default, probably `the global default timeout in socket.py <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_. None will set an infinite timeout for connection attempts. :type connect: int, float, or None :param read: The maximum amount of time (in seconds) to wait between consecutive read operations for a response from the server. Omitting the parameter will default the read timeout to the system default, probably `the global default timeout in socket.py <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_. None will set an infinite timeout. :type read: int, float, or None .. note:: Many factors can affect the total amount of time for urllib3 to return an HTTP response. For example, Python's DNS resolver does not obey the timeout specified on the socket. Other factors that can affect total request time include high CPU load, high swap, the program running at a low priority level, or other behaviors. In addition, the read and total timeouts only measure the time between read operations on the socket connecting the client and the server, not the total amount of time for the request to return a complete response. For most requests, the timeout is raised because the server has not sent the first byte in the specified time. This is not always the case; if a server streams one byte every fifteen seconds, a timeout of 20 seconds will not trigger, even though the request will take several minutes to complete. If your goal is to cut off any request after a set amount of wall clock time, consider having a second "watcher" thread to cut off a slow request.

Timeouts can be defined as a default for a pool: .. code-block:: python timeout = Timeout(connect=2.0, read=7.0) http = PoolManager(timeout=timeout) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool): .. code-block:: python response = http.request('GET', 'http://example.com/', timeout=Timeout(10)) Timeouts can be disabled by setting all the parameters to ``None``: .. code-block:: python no_timeout = Timeout(connect=None, read=None) response = http.request('GET', 'http://example.com/, timeout=no_timeout) :param total: This combines the connect and read timeouts into one; the read timeout will be set to the time leftover from the connect attempt. In the event that both a connect timeout and a total are specified, or a read timeout and a total are specified, the shorter timeout will be applied. Defaults to None. :type total: int, float, or None :param connect: The maximum amount of time (in seconds) to wait for a connection attempt to a server to succeed. Omitting the parameter will default the connect timeout to the system default, probably `the global default timeout in socket.py <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_. None will set an infinite timeout for connection attempts. :type connect: int, float, or None :param read: The maximum amount of time (in seconds) to wait between consecutive read operations for a response from the server. Omitting the parameter will default the read timeout to the system default, probably `the global default timeout in socket.py <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_. None will set an infinite timeout. :type read: int, float, or None .. note:: Many factors can affect the total amount of time for urllib3 to return an HTTP response. For example, Python's DNS resolver does not obey the timeout specified on the socket. Other factors that can affect total request time include high CPU load, high swap, the program running at a low priority level, or other behaviors. In addition, the read and total timeouts only measure the time between read operations on the socket connecting the client and the server, not the total amount of time for the request to return a complete response. For most requests, the timeout is raised because the server has not sent the first byte in the specified time. This is not always the case; if a server streams one byte every fifteen seconds, a timeout of 20 seconds will not trigger, even though the request will take several minutes to complete. If your goal is to cut off any request after a set amount of wall clock time, consider having a second "watcher" thread to cut off a slow request.

Each retry attempt will create a new Retry object with updated values, so they can be safely reused. Retries can be defined as a default for a pool:: retries = Retry(connect=5, read=2, redirect=5) http = PoolManager(retries=retries) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool):: response = http.request('GET', 'http://example.com/', retries=Retry(10)) Retries can be disabled by passing ``False``:: response = http.request('GET', 'http://example.com/', retries=False) Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless retries are disabled, in which case the causing exception will be raised. :param int total: Total number of retries to allow. Takes precedence over other counts. Set to ``None`` to remove this constraint and fall back on other counts. Set to ``0`` to fail on the first retry. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int connect: How many connection-related errors to retry on. These are errors raised before the request is sent to the remote server, which we assume has not triggered the server to process the request. Set to ``0`` to fail on the first retry of this type. :param int read: How many times to retry on read errors. These errors are raised after the request was sent to the server, so the request may have side-effects. Set to ``0`` to fail on the first retry of this type. :param int redirect: How many redirects to perform. Limit this to avoid infinite redirect loops. A redirect is a HTTP response with a status code 301, 302, 303, 307 or 308. Set to ``0`` to fail on the first retry of this type. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int status: How many times to retry on bad status codes. These are retries made on responses, where status code matches ``status_forcelist``. Set to ``0`` to fail on the first retry of this type. :param int other: How many times to retry on other errors. Other errors are errors that are not connect, read, redirect or status errors. These errors might be raised after the request was sent to the server, so the request might have side-effects. Set to ``0`` to fail on the first retry of this type. If ``total`` is not set, it's a good idea to set this to 0 to account for unexpected edge cases and avoid infinite retry loops. :param iterable allowed_methods: Set of uppercased HTTP method verbs that we should retry on. By default, we only retry on methods which are considered to be idempotent (multiple requests with the same parameters end with the same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`. Set to a ``False`` value to retry on any verb. .. warning:: Previously this parameter was named ``method_whitelist``, that usage is deprecated in v1.26.0 and will be removed in v2.0. :param iterable status_forcelist: A set of integer HTTP status codes that we should force a retry on. A retry is initiated if the request method is in ``allowed_methods`` and the response status code is in ``status_forcelist``. By default, this is disabled with ``None``. :param float backoff_factor: A backoff factor to apply between attempts after the second try (most errors are resolved immediately by a second try without a delay). urllib3 will sleep for:: {backoff factor} * (2 ** ({number of total retries} - 1)) seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer than :attr:`Retry.BACKOFF_MAX`. By default, backoff is disabled (set to 0). :param bool raise_on_redirect: Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range. :param bool raise_on_status: Similar meaning to ``raise_on_redirect``: whether we should raise an exception, or return a response, if status falls in ``status_forcelist`` range and retries have been exhausted. :param tuple history: The history of the request encountered during each call to :meth:`~Retry.increment`. The list is in the order the requests occurred. Each list item is of class :class:`RequestHistory`. :param bool respect_retry_after_header: Whether to respect Retry-After header on status codes defined as :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not. :param iterable remove_headers_on_redirect: Sequence of headers to remove from the request when a response indicating a redirect is returned before firing off the redirected request. )ZHEADZGETZPUTZDELETEZOPTIONSZTRACE)i� i� i� Z Authorization�x � Nr Tc C s� |t ur,|t urtd��tjdtdd� |}|t u r:| j}|t u rH| j}|| _|| _|| _ || _ || _ |du sv|du r~d}d} || _ |p�t � | _|| _| | _| | _| | _| p�t� | _| | _tdd� |D ��| _d S ) NzoUsing both 'allowed_methods' and 'method_whitelist' together is not allowed.

Each retry attempt will create a new Retry object with updated values, so they can be safely reused. Retries can be defined as a default for a pool:: retries = Retry(connect=5, read=2, redirect=5) http = PoolManager(retries=retries) response = http.request('GET', 'http://example.com/') Or per-request (which overrides the default for the pool):: response = http.request('GET', 'http://example.com/', retries=Retry(10)) Retries can be disabled by passing ``False``:: response = http.request('GET', 'http://example.com/', retries=False) Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless retries are disabled, in which case the causing exception will be raised. :param int total: Total number of retries to allow. Takes precedence over other counts. Set to ``None`` to remove this constraint and fall back on other counts. Set to ``0`` to fail on the first retry. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int connect: How many connection-related errors to retry on. These are errors raised before the request is sent to the remote server, which we assume has not triggered the server to process the request. Set to ``0`` to fail on the first retry of this type. :param int read: How many times to retry on read errors. These errors are raised after the request was sent to the server, so the request may have side-effects. Set to ``0`` to fail on the first retry of this type. :param int redirect: How many redirects to perform. Limit this to avoid infinite redirect loops. A redirect is a HTTP response with a status code 301, 302, 303, 307 or 308. Set to ``0`` to fail on the first retry of this type. Set to ``False`` to disable and imply ``raise_on_redirect=False``. :param int status: How many times to retry on bad status codes. These are retries made on responses, where status code matches ``status_forcelist``. Set to ``0`` to fail on the first retry of this type. :param int other: How many times to retry on other errors. Other errors are errors that are not connect, read, redirect or status errors. These errors might be raised after the request was sent to the server, so the request might have side-effects. Set to ``0`` to fail on the first retry of this type. If ``total`` is not set, it's a good idea to set this to 0 to account for unexpected edge cases and avoid infinite retry loops. :param iterable allowed_methods: Set of uppercased HTTP method verbs that we should retry on. By default, we only retry on methods which are considered to be idempotent (multiple requests with the same parameters end with the same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`. Set to a ``False`` value to retry on any verb. .. warning:: Previously this parameter was named ``method_whitelist``, that usage is deprecated in v1.26.0 and will be removed in v2.0. :param iterable status_forcelist: A set of integer HTTP status codes that we should force a retry on. A retry is initiated if the request method is in ``allowed_methods`` and the response status code is in ``status_forcelist``. By default, this is disabled with ``None``. :param float backoff_factor: A backoff factor to apply between attempts after the second try (most errors are resolved immediately by a second try without a delay). urllib3 will sleep for:: {backoff factor} * (2 ** ({number of total retries} - 1)) seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer than :attr:`Retry.BACKOFF_MAX`. By default, backoff is disabled (set to 0). :param bool raise_on_redirect: Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range. :param bool raise_on_status: Similar meaning to ``raise_on_redirect``: whether we should raise an exception, or return a response, if status falls in ``status_forcelist`` range and retries have been exhausted. :param tuple history: The history of the request encountered during each call to :meth:`~Retry.increment`. The list is in the order the requests occurred. Each list item is of class :class:`RequestHistory`. :param bool respect_retry_after_header: Whether to respect Retry-After header on status codes defined as :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not. :param iterable remove_headers_on_redirect: Sequence of headers to remove from the request when a response indicating a redirect is returned before firing off the redirected request. )ZHEADZGETZPUTZDELETEZOPTIONSZTRACE)i� i� i� Z Authorization�x � Nr Tc C s� |t ur,|t urtd��tjdtdd� |}|t u r:| j}|t u rH| j}|| _|| _|| _ || _ || _ |du sv|du r~d}d} || _ |p�t � | _|| _| | _| | _| | _| p�t� | _| | _tdd� |D ��| _d S ) NzoUsing both 'allowed_methods' and 'method_whitelist' together is not allowed.

See also simplejson's document. :param bool use_single_float: Use single precision float type for float. (default: False) :param bool autoreset: Reset buffer after each pack and return its content as `bytes`. (default: True). If set this to false, use `bytes()` to get content and `.reset()` to clear buffer. :param bool use_bin_type: Use bin type introduced in msgpack spec 2.0 for bytes. It also enables str8 type for unicode. (default: True) :param bool strict_types: If set to true, types will be checked to be exact. Derived classes from serializable types will not be serialized and will be treated as unsupported type and forwarded to default. Additionally tuples will not be serialized as lists. This is useful when trying to implement accurate serialization for python types. :param bool datetime: If set to true, datetime with tzinfo is packed into Timestamp type. Note that the tzinfo is stripped in the timestamp. You can get UTC datetime with `timestamp=3` option of the Unpacker. (Python 2 is not supported). :param str unicode_errors: The error handler for encoding unicode. (default: 'strict') DO NOT USE THIS!! This option is kept for very specific usage. Example of streaming deserialize from file-like object:: unpacker = Unpacker(file_like) for o in unpacker: process(o) Example of streaming deserialize from socket:: unpacker = Unpacker() while True: buf = sock.recv(1024**2) if not buf: break unpacker.feed(buf) for o in unpacker: process(o) Raises ``ExtraData`` when *packed* contains extra bytes. Raises ``OutOfData`` when *packed* is incomplete. Raises ``FormatError`` when *packed* is not valid msgpack. Raises ``StackError`` when *packed* contains too nested.

Arguments: :param file_like: File-like object having `.read(n)` method. If specified, unpacker reads serialized data from it and :meth:`feed()` is not usable. :param int read_size: Used as `file_like.read(read_size)`. (default: `min(16*1024, max_buffer_size)`) :param bool use_list: If true, unpack msgpack array to Python list. Otherwise, unpack to Python tuple. (default: True) :param bool raw: If true, unpack msgpack raw to Python bytes. Otherwise, unpack to Python str by decoding with UTF-8 encoding (default). :param int timestamp: Control how timestamp type is unpacked: 0 - Timestamp 1 - float (Seconds from the EPOCH) 2 - int (Nanoseconds from the EPOCH) 3 - datetime.datetime (UTC). Python 2 is not supported. :param bool strict_map_key: If true (default), only str or bytes are accepted for map (dict) keys. :param callable object_hook: When specified, it should be callable. Unpacker calls it with a dict argument after unpacking msgpack map. (See also simplejson) :param callable object_pairs_hook: When specified, it should be callable. Unpacker calls it with a list of key-value pairs after unpacking msgpack map. (See also simplejson) :param str unicode_errors: The error handler for decoding unicode. (default: 'strict') This option should be used only when you have msgpack data which contains invalid UTF-8 string. :param int max_buffer_size: Limits size of data waiting unpacked. 0 means 2**32-1. The default value is 100*1024*1024 (100MiB). Raises `BufferFull` exception when it is insufficient. You should set this parameter when unpacking data from untrusted source. :param int max_str_len: Deprecated, use *max_buffer_size* instead. Limits max length of str. (default: max_buffer_size) :param int max_bin_len: Deprecated, use *max_buffer_size* instead. Limits max length of bin. (default: max_buffer_size) :param int max_array_len: Limits max length of array. (default: max_buffer_size) :param int max_map_len: Limits max length of map. (default: max_buffer_size//2) :param int max_ext_len: Deprecated, use *max_buffer_size* instead. Limits max size of ext type. (default: max_buffer_size) Example of streaming deserialize from file-like object:: unpacker = Unpacker(file_like) for o in unpacker: process(o) Example of streaming deserialize from socket:: unpacker = Unpacker(max_buffer_size) while True: buf = sock.recv(1024**2) if not buf: break unpacker.feed(buf) for o in unpacker: process(o) Raises ``ExtraData`` when *packed* contains extra bytes. Raises ``OutOfData`` when *packed* is incomplete. Raises ``FormatError`` when *packed* is not valid msgpack. Raises ``StackError`` when *packed* contains too nested.

See also simplejson's document. :param bool use_single_float: Use single precision float type for float. (default: False) :param bool autoreset: Reset buffer after each pack and return its content as `bytes`. (default: True). If set this to false, use `bytes()` to get content and `.reset()` to clear buffer. :param bool use_bin_type: Use bin type introduced in msgpack spec 2.0 for bytes. It also enables str8 type for unicode. (default: True) :param bool strict_types: If set to true, types will be checked to be exact. Derived classes from serializable types will not be serialized and will be treated as unsupported type and forwarded to default. Additionally tuples will not be serialized as lists. This is useful when trying to implement accurate serialization for python types. :param bool datetime: If set to true, datetime with tzinfo is packed into Timestamp type. Note that the tzinfo is stripped in the timestamp. You can get UTC datetime with `timestamp=3` option of the Unpacker. (Python 2 is not supported). :param str unicode_errors: The error handler for encoding unicode. (default: 'strict') DO NOT USE THIS!! This option is kept for very specific usage. Example of streaming deserialize from file-like object:: unpacker = Unpacker(file_like) for o in unpacker: process(o) Example of streaming deserialize from socket:: unpacker = Unpacker() while True: buf = sock.recv(1024**2) if not buf: break unpacker.feed(buf) for o in unpacker: process(o) Raises ``ExtraData`` when *packed* contains extra bytes. Raises ``OutOfData`` when *packed* is incomplete. Raises ``FormatError`` when *packed* is not valid msgpack. Raises ``StackError`` when *packed* contains too nested. Other exceptions can be raised during unpacking.

Those with few left should likely be worked on first, I guess? * Are there any known conflicts for this requirement? We should probably work on those with the most known conflicts. A sortable value should be returned (this will be used as the ``key`` parameter of the built-in sorting function). The smaller the value is, the more preferred this requirement is (i.e. the sorting function is called with ``reverse=False``).

This identifies the dependency matches of which should be returned. :param requirements: A mapping of requirements that all returned candidates must satisfy. Each key is an identifier, and the value an iterator of requirements for that dependency. :param incompatibilities: A mapping of known incompatibilities of each dependency. Each key is an identifier, and the value an iterator of incompatibilities known to the resolver. All incompatibilities *must* be excluded from the return value. This should try to get candidates based on the requirements' types. For VCS, local, and archive requirements, the one-and-only match is returned, and for a "named" requirement, the index(es) should be consulted to find concrete candidates for this requirement. The return value should produce candidates ordered by preference; the most preferred candidate should come first. The return type may be one of the following: * A callable that returns an iterator that yields candidates. * An collection of candidates. * An iterable of candidates.

When we enter here, the stack is like this:: [ state Z ] [ state Y ] [ state X ] .... earlier states are irrelevant. 1. No pins worked for Z, so it does not have a pin. 2. We want to reset state Y to unpinned, and pin another candidate. 3. State X holds what state Y was before the pin, but does not have the incompatibility information gathered in state Y. Each iteration of the loop will: 1. Discard Z. 2. Discard Y but remember its incompatibility information gathered previously, and the failure we're dealing with right now. 3. Push a new state Y' based on X, and apply the incompatibility information from Y to Y'. 4a. If this causes Y' to conflict, we need to backtrack again. Make Y' the new Z and go back to step 2. 4b.

The return value is a representation to the final resolution result. It is a tuple subclass with three public members: * `mapping`: A dict of resolved candidates. Each key is an identifier of a requirement (as returned by the provider's `identify` method), and the value is the resolved candidate. * `graph`: A `DirectedGraph` instance representing the dependency tree. The vertices are keys of `mapping`, and each edge represents *why* a particular package is included. A special vertex `None` is included to represent parents of user-supplied requirements. * `criteria`: A dict of "criteria" that hold detailed information on how edges in the graph are derived. Each key is an identifier of a requirement, and the value is a `Criterion` instance. The following exceptions may be raised if a resolution cannot be found: * `ResolutionImpossible`: A resolution cannot be found for the given combination of requirements. The `causes` attribute of the exception is a list of (requirement, parent), giving the requirements that could not be satisfied. * `ResolutionTooDeep`: The dependency tree is too deeply nested and the resolver gave up.

When we enter here, the stack is like this:: [ state Z ] [ state Y ] [ state X ] .... earlier states are irrelevant. 1. No pins worked for Z, so it does not have a pin. 2. We want to reset state Y to unpinned, and pin another candidate. 3. State X holds what state Y was before the pin, but does not have the incompatibility information gathered in state Y. Each iteration of the loop will: 1. Discard Z. 2. Discard Y but remember its incompatibility information gathered previously, and the failure we're dealing with right now. 3. Push a new state Y' based on X, and apply the incompatibility information from Y to Y'. 4a. If this causes Y' to conflict, we need to backtrack again. Make Y' the new Z and go back to step 2. 4b.

The vertices are keys of `mapping`, and each edge represents *why* a particular package is included. A special vertex `None` is included to represent parents of user-supplied requirements. * `criteria`: A dict of "criteria" that hold detailed information on how edges in the graph are derived. Each key is an identifier of a requirement, and the value is a `Criterion` instance. The following exceptions may be raised if a resolution cannot be found: * `ResolutionImpossible`: A resolution cannot be found for the given combination of requirements. The `causes` attribute of the exception is a list of (requirement, parent), giving the requirements that could not be satisfied. * `ResolutionTooDeep`: The dependency tree is too deeply nested and the resolver gave up.

A *requirement information* instance is a named tuple with two members: * ``requirement`` specifies a requirement contributing to the current list of candidates. * ``parent`` specifies the candidate that provides (dependend on) the requirement, or ``None`` to indicate a root requirement. The preference could depend on a various of issues, including (not necessarily in this order): * Is this package pinned in the current resolution result? * How relaxed is the requirement? Stricter ones should probably be worked on first? (I don't know, actually.) * How many possibilities are there to satisfy this requirement? Those with few left should likely be worked on first, I guess? * Are there any known conflicts for this requirement? We should probably work on those with the most known conflicts. A sortable value should be returned (this will be used as the ``key`` parameter of the built-in sorting function).

Each key is an identifier, and the value an iterator of incompatibilities known to the resolver. All incompatibilities *must* be excluded from the return value. This should try to get candidates based on the requirements' types. For VCS, local, and archive requirements, the one-and-only match is returned, and for a "named" requirement, the index(es) should be consulted to find concrete candidates for this requirement. The return value should produce candidates ordered by preference; the most preferred candidate should come first.

It allows for a customized multiplier and an ability to restrict the upper and lower limits to some maximum and minimum value. The intervals are fixed (i.e. there is no jitter), so this strategy is suitable for balancing retries against latency when a required resource is unavailable for an unknown duration, but *not* suitable for resolving contention between multiple processes for a shared resource. Use wait_random_exponential for the latter case. r' � r N)� multiplierr) �exp_baser( r c C s || _ || _|| _|| _d S r )rE r( r) rF )r rE r) rF r( r r r r � s zwait_exponential.__init__r r c C sR z | j |jd }| j| }W n ty6 | j Y S 0 ttd| j�t|| j��S r@ )rF r: rE � OverflowErrorr) r( )r r ZexprA r r r r � s zwait_exponential.__call__rB r r r r rC � s � � rC c s( e Zd ZdZded�� fdd� Z� ZS )�wait_random_exponentiala Random wait with exponentially widening window. An exponential backoff strategy used to mediate contention between multiple uncoordinated processes for a shared resource in distributed systems. This is the sense in which "exponential backoff" is meant in e.g. Ethernet networking, and corresponds to the "Full Jitter" algorithm described in this blog post: https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/ Each retry occurs at a random time in a geometrically expanding interval. It allows for a custom multiplier and an ability to restrict the upper limit of the random interval to some maximum value. Example:: wait_random_exponential(multiplier=0.5, # initial window 0.5s max=60) # max 60s timeout When waiting for an unavailable resource to become available again, as opposed to trying to resolve contention for a shared resource, the wait_exponential strategy (which uses a fixed interval) may be preferable. r r c s t � j|d�}t�d|�S )Nr2 r )r" r r, Zuniform)r r Zhighr# r r r � s z wait_random_exponential.__call__)r r r r r r r% r r r# r rH � s rH )r r, r Zpip._vendor.tenacityr � TYPE_CHECKINGr �ABCr r r! r& r r9 r< rC rH r r r r �<module> s "PK �n�Z^ Q�� � : _vendor/tenacity/__pycache__/_asyncio.cpython-39.opt-1.pycnu �[��� a [��f� � @ s� d dl Z d dlZd dlZd dlmZ d dlmZ d dlmZ d dlmZ d dlm Z d dlm Z ej dej d �Z e� d �ZG d d � d e�ZdS ) � N)�sleep)�AttemptManager)� BaseRetrying)� DoAttempt)�DoSleep)�RetryCallState� WrappedFn)�bound�_RetValTc s� e Zd Zefejegejf ejdd�� fdd� Z ejdeje f ejeje d�dd�Z d d �d d �Z ej eejf d �d d �Zeed�� fdd� Z� ZS )� AsyncRetryingN)r �kwargs�returnc s t � jf i |�� || _d S �N)�super�__init__r )�selfr r �� __class__� �A/usr/lib/python3.9/site-packages/pip/_vendor/tenacity/_asyncio.pyr " s zAsyncRetrying.__init__.)�fn�argsr r c � s� | � � t| |||d�}| j|d�}t|t�rtz||i |��I d H }W n tyf |�t�� � Y q�0 |� |� qt|t �r�|� � | � |�I d H q|S qd S )N)Z retry_objectr r r �� retry_state) �beginr �iter� isinstancer � BaseExceptionZ set_exception�sys�exc_infoZ set_resultr �prepare_for_next_attemptr )r r r r r �do�resultr r r �__call__& s zAsyncRetrying.__call__)r c C s | � � t| d di d�| _| S )Nr )r r r )r r � _retry_state)r r r r � __aiter__> s zAsyncRetrying.__aiter__c � sb | j | jd�}|d u r t�q t|t�r2t| jd�S t|t�rX| j�� | �|�I d H q |S q d S )Nr ) r r$ �StopAsyncIterationr r r r r r )r r! r r r � __anext__C s zAsyncRetrying.__anext__)r r c sF t � �� �� t�� �tjtjtjd�� fdd� �}� j|_� j|_|S )N)r r r c � s � | i |��I d H S r r )r r �r r r � async_wrappedT s z*AsyncRetrying.wraps.<locals>.async_wrapped)r �wraps� functools�typing�AnyZretryZ retry_with)r r r) r r( r r* P s zAsyncRetrying.wraps)�__name__� __module__� __qualname__r r, �Callable�float� Awaitabler- r r r# r% �Unionr r' r r* � __classcell__r r r r r ! s *� r )r+ r r, Zasyncior Zpip._vendor.tenacityr r r r r �TypeVarr1 r r r r r r r �<module> s PK �n�Z\5 � � 2 _vendor/tenacity/__pycache__/_utils.cpython-39.pycnu �[��� a [��f� � @ sZ d dl Z d dlZe jd Zeed�dd�Zeed�dd�Zejdej f ed �d d �Z dS ) � N� )�pos_num�returnc C s\ | dkr dS | dkrdS | dkr$dS | dkr0dS d | krDd krLn ndS t | d �S d S ) Nr �th� �str Znd� Zrd� � � �� find_ordinal�r � r �?/usr/lib/python3.9/site-packages/pip/_vendor/tenacity/_utils.pyr s r c C s | � t | �� �S )Nr r r r r � to_ordinal* s r .)�cbr c C s� g }z|� | j� W n6 tyJ z|� | j� W n tyD Y n0 Y n0 |sXt| �S z| jrn|�d| j� W n ty� Y n0 d�|�S dS )znGet a callback fully-qualified name.

It allows for a customized multiplier and an ability to restrict the upper and lower limits to some maximum and minimum value. The intervals are fixed (i.e. there is no jitter), so this strategy is suitable for balancing retries against latency when a required resource is unavailable for an unknown duration, but *not* suitable for resolving contention between multiple processes for a shared resource.

An exponential backoff strategy used to mediate contention between multiple uncoordinated processes for a shared resource in distributed systems. This is the sense in which "exponential backoff" is meant in e.g. Ethernet networking, and corresponds to the "Full Jitter" algorithm described in this blog post: https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/ Each retry occurs at a random time in a geometrically expanding interval. It allows for a custom multiplier and an ability to restrict the upper limit of the random interval to some maximum value. Example:: wait_random_exponential(multiplier=0.5, # initial window 0.5s max=60) # max 60s timeout When waiting for an unavailable resource to become available again, as opposed to trying to resolve contention for a shared resource, the wait_exponential strategy (which uses a fixed interval) may be preferable. r r c s t � j|d�}t�d|�S )Nr2 r )r" r r, Zuniform)r r Zhighr# r r r � s z wait_random_exponential.__call__)r r r r r r r% r r r# r rH � s rH )r r, r Zpip._vendor.tenacityr � TYPE_CHECKINGr �ABCr r r! r& r r9 r< rC rH r r r r �<module> s "PK �n�Z� �Bs? s? : _vendor/tenacity/__pycache__/__init__.cpython-39.opt-1.pycnu �[��� a [��fQG � @ s� d dl Z d dlZd dlZd dlZd dlZd dlZd dlmZm Z d dl m Z d dl m Z ddlmZ ddlmZ ddlmZ dd lmZ dd lmZ dd lmZ dd lmZ dd lmZ ddlmZ ddlmZ ddlmZ ddlmZ ddlmZ ddl m Z ddl m Z ddl m Z ddl m!Z! ddl m"Z" ddl m#Z# ddl m$Z$ ddl m%Z% ddl&m'Z' dd l&m(Z( dd l&m)Z) dd l&m*Z* dd l&m+Z+ dd l&m,Z, dd!l&m-Z- dd"l&m.Z. dd"l&m.Z/ dd#l0m1Z1 dd$l0m2Z2 dd%l3m4Z4 dd&l3m5Z5 dd'l6m7Z7 dd(l6m8Z8 dZ9ej:�r4d dl;Z;dd)l&m<Z< dd*l m=Z= ej>d+ej?d,�Z@e�>d-�ZAejBe@e@d.�d/d0��ZejBejCejCej?e@ge@f d1�d2d0��ZejCejCejDe@ej?e@ge@f f d1�d3d0�ZG d4d5� d5eE�ZFeG� ZHG d6d7� d7�ZIG d8d9� d9eJ�ZKG d:d;� d;�ZLG d<d=� d=eL�ZMeG� ZNejDejCeGf ejCejCd>�d?d@�ZOG dAdB� dBeE�ZPG dCdD� dD�ZQG dEdF� dFe�ZRG dGdH� dHeR�ZSG dIdJ� dJe jT�ZTG dKdL� dL�ZUd dMlVmWZW e9�r�d dNlXmYZY dS )O� N)�ABC�abstractmethod)�futures)�iscoroutinefunction� )� retry_base)� retry_all)� retry_always)� retry_any)�retry_if_exception)�retry_if_exception_type)�retry_if_not_exception_type)�retry_if_not_result)�retry_if_result)� retry_never)�retry_unless_exception_type)�retry_if_exception_message)� retry_if_not_exception_message��sleep)�sleep_using_event)�stop_after_attempt)�stop_after_delay)�stop_all)�stop_any)� stop_never)�stop_when_event_set)� wait_chain)� wait_combine)�wait_exponential)� wait_fixed)�wait_incrementing)� wait_none)� wait_random)�wait_random_exponential)� before_log)�before_nothing)� after_log)� after_nothing)�before_sleep_log)�before_sleep_nothing)� wait_base)� stop_base� WrappedFn)�bound�_RetValT)�fn�returnc C s d S �N� )r0 r3 r3 �A/usr/lib/python3.9/site-packages/pip/_vendor/tenacity/__init__.py�retrya s r5 )�dargs�dkwr1 c O s d S r2 r3 �r6 r7 r3 r3 r4 r5 f s c sD t � �dkr&t� d �r&t� � d �S ttd�� �fdd� }|S dS )z�Wrap a function with a new `Retrying` object. :param dargs: positional arguments passed to Retrying object :param dkw: keyword arguments passed to the Retrying object r r ��fr1 c s� t | t�r*t�d| jj� d| jj� d�� t| �rBt� i ���}n:trnt tj d�rntj � | �rnt � i ���}nt � i ���}|�| �S )NzGot retry_base instance (zQ) as callable argument, this will probably hang indefinitely (did you mean retry=z(...)?)�is_coroutine_function)� isinstancer �warnings�warn� __class__�__name__r � AsyncRetrying�tornado�hasattr�genr; �TornadoRetrying�Retrying�wraps)r: �rr8 r3 r4 �wrapv s �� zretry.<locals>.wrapN)�len�callabler5 r- )r6 r7 rI r3 r8 r4 r5 k s c @ s e Zd ZdZdS )�TryAgainz/Always retry the executed function when raised.N)r@ � __module__� __qualname__�__doc__r3 r3 r3 r4 rL � s rL c @ s e Zd ZdS )� DoAttemptN�r@ rM rN r3 r3 r3 r4 rP � s rP c @ s e Zd ZdS )�DoSleepNrQ r3 r3 r3 r4 rR � s rR c @ sR e Zd ZU dZdZeje ed< dZ ej e ed< ed�dd�Z ed�d d �Z dS ) � BaseActiona5 Base class for representing actions to take by retry object.

The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. � )�absolute_importN)� get_importer)�six)�urllib�map�filter)�utime)�mkdir�rename�unlinkTF)�open)�isdir�split� )� py31compat)� platformdirs)� packagingz pip._vendor.packaging.versionz pip._vendor.packaging.specifiersz"pip._vendor.packaging.requirementsz pip._vendor.packaging.markers)� r )r � z Python 3.5 or later is requiredc @ s e Zd ZdZdS )� PEP440Warningza Used when there is an issue with a version or specifier not complying with PEP 440.

But what we want when checking compatibility is to know the version of Mac OS X that we are *running*. To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS. If this condition occurs for any other platform with a version in its platform strings, this function should be extended accordingly.

Unless `replace_conflicting=True`, raises a VersionConflict exception if any requirements are found on the path that have the correct name but the wrong version. Otherwise, if an `installer` is supplied it will be invoked to obtain the correct version of the requirement and activate it. `extras` is a list of the extras to be used with these requirements. This is important because extra requirements may look like `my_req; extra = "my_extra"`, which would otherwise be interpreted as a purely optional requirement. Instead, we want to be able to assert that these requirements are truly required.

The `full_env`, if supplied, should be an ``Environment`` contains all currently-available distributions. If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred.

(Which is based on the ``PYTHON_EGG_CACHE`` environment variable, with various platform-specific fallbacks. See that routine's documentation for more details.) Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files.

The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is. Do not use os.path operations to manipulate resource names being passed into the API. The package resource API is designed to work with normal filesystem packages, .egg files, and unpacked .egg files. It can also work in a limited way with .zip files and with custom PEP 302 loaders that support the ``get_data()`` method. � )�absolute_importN)� get_importer)�six)�urllib�map�filter)�utime)�mkdir�rename�unlinkTF)�open)�isdir�split� )� py31compat)� platformdirs)� packagingz pip._vendor.packaging.versionz pip._vendor.packaging.specifiersz"pip._vendor.packaging.requirementsz pip._vendor.packaging.markers)� r )r � z Python 3.5 or later is requiredc @ s e Zd ZdZdS )� PEP440Warningza Used when there is an issue with a version or specifier not complying with PEP 440.

But what we want when checking compatibility is to know the version of Mac OS X that we are *running*. To allow usage of packages that explicitly require a newer version of Mac OS X, we must also know the current version of the OS. If this condition occurs for any other platform with a version in its platform strings, this function should be extended accordingly.

If not supplied, it defaults to all distributions available within any entry or distribution in the working set. `installer`, if supplied, will be invoked with each requirement that cannot be met by an already-installed distribution; it should return a ``Distribution`` or ``None``. Unless `replace_conflicting=True`, raises a VersionConflict exception if any requirements are found on the path that have the correct name but the wrong version. Otherwise, if an `installer` is supplied it will be invoked to obtain the correct version of the requirement and activate it. `extras` is a list of the extras to be used with these requirements. This is important because extra requirements may look like `my_req; extra = "my_extra"`, which would otherwise be interpreted as a purely optional requirement.

The `full_env`, if supplied, should be an ``Environment`` contains all currently-available distributions. If `full_env` is not supplied, one is created automatically from the ``WorkingSet`` this method is called on, which will typically mean that every directory on ``sys.path`` will be scanned for distributions. `installer` is a standard installer callback as used by the ``resolve()`` method. The `fallback` flag indicates whether we should attempt to resolve older versions of a plugin if the newest version cannot be resolved. This method returns a 2-tuple: (`distributions`, `error_info`), where `distributions` is a list of the distributions found in `plugin_env` that were loadable, along with any other distributions that are needed to resolve their dependencies. `error_info` is a dictionary mapping unloadable plugin distributions to an exception instance describing the error that occurred. Usually this will be a ``DistributionNotFound`` or ``VersionConflict`` instance.

Snapshot distributions available on a search path Any distributions found on `search_path` are added to the environment. `search_path` should be a sequence of ``sys.path`` items. If not supplied, ``sys.path`` is used. `platform` is an optional string specifying the name of the platform that platform-specific distributions must be compatible with. If unspecified, it defaults to the current platform. `python` is an optional string naming the desired version of Python (e.g. ``'3.6'``); it defaults to the current version. You may explicitly set `platform` (and/or `python`) to ``None`` if you wish to map *all* distributions, not just those compatible with the running platform or Python version.

If a suitable distribution isn't active, this method returns the newest distribution in the environment that meets the ``Requirement`` in `req`.

Resource providers should call this method ONLY after successfully extracting a compressed resource.

If you do not call this routine before any extractions take place, the path defaults to the return value of ``get_default_cache()``. (Which is based on the ``PYTHON_EGG_CACHE`` environment variable, with various platform-specific fallbacks. See that routine's documentation for more details.) Resources are extracted to subdirectories of this path based upon information given by the ``IResourceProvider``. You may set this to a temporary directory, but then you must call ``cleanup_resources()`` to delete the extracted files when done. There is no guarantee that ``cleanup_resources()`` will be able to remove all extracted files.

The package resource API expects resource names to have their path parts separated with ``/``, *not* whatever the local path separator is.

The dependency relationships are stored in an ``adjacency_list`` that maps distributions to a list of ``(other, label)`` tuples where ``other`` is a distribution and the edge is labeled with ``label`` (i.e. the version specifier, if such was provided). Also, for more efficient traversal, for every distribution ``x``, a list of predecessors is kept in ``reverse_list[x]``. An edge from distribution ``a`` to distribution ``b`` means that ``a`` depends on ``b``. If any missing dependencies are found, they are stored in ``missing``, which is a dictionary that maps distributions to a list of requirements that were not provided by any other distributions. c C s i | _ i | _i | _d S r9 )�adjacency_list� reverse_listr� r! r# r# r$ r% I s zDependencyGraph.__init__c C s g | j |< g | j|< dS )z�Add the *distribution* to the graph. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` N)r r )r" � distributionr# r# r$ �add_distributionN s z DependencyGraph.add_distributionNc C s6 | j | �||f� || j| vr2| j| �|� dS )a� Add an edge from distribution *x* to distribution *y* with the given *label*. :type x: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type y: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type label: ``str`` or ``None`` N)r r) r )r" �x�y�labelr# r# r$ �add_edgeX s zDependencyGraph.add_edgec C s& t �d||� | j�|g ��|� dS )a Add a missing *requirement* for the given *distribution*. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type requirement: ``str`` z %s missing %rN)rS rT r� r' r) )r" r r� r# r# r$ � add_missingg s zDependencyGraph.add_missingc C s d|j |jf S r� r� r* r# r# r$ � _repr_distr s zDependencyGraph._repr_distr c C s� | � |�g}| j| D ]h\}}| � |�}|dur<d||f }|�d| t|� � | �||d �}|�d�}|�|dd� � qd�|�S )zPrints only a subgraphNz%s [%s]z r r� )r% r r) r� � repr_noder� �extendrO )r" r+ �level�outputr� r" Z suboutputZsubsr# r# r$ r& u s zDependencyGraph.repr_nodeTc C s� g }|� d� | j�� D ]h\}}t|�dkr:|s:|�|� |D ]@\}}|durh|� d|j|j|f � q>|� d|j|jf � q>q|s�t|�dkr�|� d� |� d� |� d� |D ] }|� d |j � |� d � q�|� d � |� d � dS ) a9 Writes a DOT output for the graph to the provided file *f*.

Patterns are not quite the same as implemented by the 'fnmatch' module: '*' and '?' match non-special characters, where "special" is platform-dependent: slash on Unix; colon, slash, and backslash on DOS/Windows; and colon on Mac OS. If 'anchor' is true (the default), then the pattern match is more stringent: "*.py" will match "foo.py" but not "foo/bar.py". If 'anchor' is false, both of these will match. If 'prefix' is supplied, then only filenames starting with 'prefix' (itself a pattern) and ending with 'pattern', with anything in between them, will match. 'anchor' is ignored in this case. If 'is_regex' is true, 'anchor' and 'prefix' are ignored, and 'pattern' is assumed to be either a string containing a regex or a regex object -- no translation is done, the regex is just compiled and used as-is.

If 'anchor' is true (the default), then the pattern match is more stringent: "*.py" will match "foo.py" but not "foo/bar.py". If 'anchor' is false, both of these will match. If 'prefix' is supplied, then only filenames starting with 'prefix' (itself a pattern) and ending with 'pattern', with anything in between them, will match. 'anchor' is ignored in this case. If 'is_regex' is true, 'anchor' and 'prefix' are ignored, and 'pattern' is assumed to be either a string containing a regex or a regex object -- no translation is done, the regex is just compiled and used as-is.

If kwarg ``warner`` is specified, it should be a callable, which will be called with two tuples indicating the wheel version of this software and the wheel version in the file, if there is a discrepancy in the versions. This can be used to issue any warnings to raise any exceptions. If kwarg ``lib_only`` is True, only the purelib/platlib files are installed, and the headers, scripts, data and dist-info metadata are not written. If kwarg ``bytecode_hashed_invalidation`` is True, written bytecode will try to use file-hash based invalidation (PEP-552) on supported interpreter versions (CPython 2.7+). The return value is a :class:`InstalledDistribution` instance unless ``options.lib_only`` is True, in which case the return value is ``None``. �warner�lib_onlyFZ bytecode_hashed_invalidationrs r� rt r� r� ru rv Nrw r$ r c S s g | ] }t |��qS r/ rx rz r/ r/ r0 r} � r7 z!Wheel.install.<locals>.<listcomp>zRoot-Is-Purelibr� r� r� ��streamr r) r� )�dry_runTr �size mismatch for %s�=�digest mismatch for %szlib_only: skipping %sr� r2 �posix� i� r� z digest mismatch on write for %sz.py)Zhashed_invalidationzByte-compilation failed)�exc_infozlib_only: returning Nonez1.0zentry_points.txt)Zconsole�guiz %s_scriptszwrap_%sz%s:%sz [%s]�,zAUnable to read legacy script metadata, so cannot generate scriptsrC zpython.commandsz8Unable to read JSON metadata, so cannot generate scriptsZ wrap_consoleZwrap_guiz Valid script path not specifiedz%s = %sr� �lib�prefixzinstallation failed.)Ir� r� r9 rJ r- rd rg re rf r� r r~ r r r� r rk r� r� r r �recordrM �dont_write_bytecode�tempfileZmkdtempZ source_dirZ target_dir�infolist� isinstancer r� r� �str� file_sizer r� r� � startswithr� r� r� r Z copy_stream�chmodZ external_attrr, Z byte_compile� ExceptionZwarning�basenameZmakeZset_executable_mode�extendro r �valuesr� �suffix�flags�json�loadr� r� �itemsr r� Zwrite_shared_locationsZwrite_installed_files�shutil�rmtree� exceptionZrollback)Cr? r� Zmaker�kwargsr� r� r� Zbc_hashed_invalidationrB r� r� r� � metadata_name�wheel_metadata_name� record_namer� r� �bwfr� r� r� r� r� r� r� �readerr� r� Zdata_pfxZinfo_pfxZ script_pfxZfileopZbcZoutfiles�workdir�zinfor� � u_arcname�kind�valuer� r# r� Z is_script�wherer� ZoutfileZ newdigestZpycr� Zworknamer� � filenamesZdistZcommandsZepZepdatar� rF r% rG �sZconsole_scriptsZ gui_scriptsZ script_dirZscript�optionsr/ r/ r0 �install� s\ & L � ( � � , �&�� , ( . � � z Wheel.installc C s8 t d u r4tj�t� td�dtjd d� �}t|�a t S )Nz dylib-cachez%s.%sr ) �cacher9 rJ r- r r rM � version_infor )r? r� r/ r/ r0 �_get_dylib_cache� s �zWheel._get_dylib_cachec C s� t j�| j| j�}d| j| jf }d| }t�|d�}t� d�}g }t |d���.}�z|� |���}||�} t � | �} | �� } | �|�} t j�| j| �} t j�| �s�t �| � | �� D ]�\}}t j�| t|��}t j�|�s�d}n6t �|�j}tj�|�}|�|�}tj|j� }||k}|�r(|� || � |� ||f� q�W d � n1 �sN0 Y W n t �yn Y n0 W d � n1 �s�0 Y |S )Nrs rt Z EXTENSIONSru rv T) r9 rJ r- rd rg re rf r� r~ r r r� r r r% Z prefix_to_dirr� r� �makedirsr r rq �stat�st_mtime�datetimeZ fromtimestampZgetinfoZ date_time�extractr, r� )r? rB r� r� r� r� rK r� r� r� rC r# r� Z cache_basere r� �destr* Z file_timero Z wheel_timer/ r/ r0 �_get_extensions� s> 4&zWheel._get_extensionsc C s t | �S )zM Determine if a wheel is compatible with the running system. )� is_compatibler> r/ r/ r0 r- � s zWheel.is_compatiblec C s dS )zP Determine if a wheel is asserted as mountable by its metadata.

The modifier should be a callable which expects a dictionary argument: its keys are archive-entry paths, and its values are absolute filesystem paths where the contents the corresponding archive entries can be found. The modifier is free to change the contents of the files pointed to, add new entries and remove entries, before returning. This method will extract the entire contents of the wheel to a temporary location, call the modifier, and then use the passed (and possibly updated) dictionary to write a new wheel. If ``dest_dir`` is specified, the new wheel is written there -- otherwise, the original wheel is overwritten. The modifier should return True if it updated the wheel, else False.

If kwarg ``warner`` is specified, it should be a callable, which will be called with two tuples indicating the wheel version of this software and the wheel version in the file, if there is a discrepancy in the versions. This can be used to issue any warnings to raise any exceptions. If kwarg ``lib_only`` is True, only the purelib/platlib files are installed, and the headers, scripts, data and dist-info metadata are not written. If kwarg ``bytecode_hashed_invalidation`` is True, written bytecode will try to use file-hash based invalidation (PEP-552) on supported interpreter versions (CPython 2.7+). The return value is a :class:`InstalledDistribution` instance unless ``options.lib_only`` is True, in which case the return value is ``None``. �warner�lib_onlyFZ bytecode_hashed_invalidationrs r� rt r� r� ru rv Nrw r$ r c S s g | ] }t |��qS r/ rx rz r/ r/ r0 r} � r7 z!Wheel.install.<locals>.<listcomp>zRoot-Is-Purelibr� r� r� ��streamr r) r� )�dry_runTr �size mismatch for %s�=�digest mismatch for %szlib_only: skipping %sr� r2 �posix� i� r� z digest mismatch on write for %sz.py)Zhashed_invalidationzByte-compilation failed)�exc_infozlib_only: returning Nonez1.0zentry_points.txt)Zconsole�guiz %s_scriptszwrap_%sz%s:%sz [%s]�,zAUnable to read legacy script metadata, so cannot generate scriptsrC zpython.commandsz8Unable to read JSON metadata, so cannot generate scriptsZ wrap_consoleZwrap_guiz Valid script path not specifiedz%s = %sr� �lib�prefixzinstallation failed.)Ir� r� r9 rJ r- rd rg re rf r� r r~ r r r� r rk r� r� r r �recordrM �dont_write_bytecode�tempfileZmkdtempZ source_dirZ target_dir�infolist� isinstancer r� r� �str� file_sizer r� r� � startswithr� r� r� r Z copy_stream�chmodZ external_attrr, Z byte_compile� ExceptionZwarning�basenameZmakeZset_executable_mode�extendro r �valuesr� �suffix�flags�json�loadr� r� �itemsr r� Zwrite_shared_locationsZwrite_installed_files�shutil�rmtree� exceptionZrollback)Cr? r� Zmaker�kwargsr� r� r� Zbc_hashed_invalidationrB r� r� r� � metadata_name�wheel_metadata_name� record_namer� r� �bwfr� r� r� r� r� r� r� �readerr� r� Zdata_pfxZinfo_pfxZ script_pfxZfileopZbcZoutfiles�workdir�zinfor� � u_arcname�kind�valuer� r# r� Z is_script�wherer� ZoutfileZ newdigestZpycr� Zworknamer� � filenamesZdistZcommandsZepZepdatar� rF r% rG �sZconsole_scriptsZ gui_scriptsZ script_dirZscript�optionsr/ r/ r0 �install� s\ & L � ( � � , �&�� , ( . � � z Wheel.installc C s8 t d u r4tj�t� td�dtjd d� �}t|�a t S )Nz dylib-cachez%s.%sr ) �cacher9 rJ r- r r rM � version_infor )r? r� r/ r/ r0 �_get_dylib_cache� s �zWheel._get_dylib_cachec C s� t j�| j| j�}d| j| jf }d| }t�|d�}t� d�}g }t |d���.}�z|� |���}||�} t � | �} | �� } | �|�} t j�| j| �} t j�| �s�t �| � | �� D ]�\}}t j�| t|��}t j�|�s�d}n6t �|�j}tj�|�}|�|�}tj|j� }||k}|�r(|� || � |� ||f� q�W d � n1 �sN0 Y W n t �yn Y n0 W d � n1 �s�0 Y |S )Nrs rt Z EXTENSIONSru rv T) r9 rJ r- rd rg re rf r� r~ r r r� r r r% Z prefix_to_dirr� r� �makedirsr r rq �stat�st_mtime�datetimeZ fromtimestampZgetinfoZ date_time�extractr, r� )r? rB r� r� r� r� rK r� r� r� rC r# r� Z cache_basere r� �destr* Z file_timero Z wheel_timer/ r/ r0 �_get_extensions� s> 4&zWheel._get_extensionsc C s t | �S )zM Determine if a wheel is compatible with the running system. )� is_compatibler> r/ r/ r0 r- � s zWheel.is_compatiblec C s dS )zP Determine if a wheel is asserted as mountable by its metadata.

The modifier should be a callable which expects a dictionary argument: its keys are archive-entry paths, and its values are absolute filesystem paths where the contents the corresponding archive entries can be found. The modifier is free to change the contents of the files pointed to, add new entries and remove entries, before returning. This method will extract the entire contents of the wheel to a temporary location, call the modifier, and then use the passed (and possibly updated) dictionary to write a new wheel. If ``dest_dir`` is specified, the new wheel is written there -- otherwise, the original wheel is overwritten. The modifier should return True if it updated the wheel, else False. This method returns the same value the modifier returns. c S sH d }}d|t f }|| vr$d| }|| v r@| | }t|d�j}||fS )Nz%s/%sz %s/PKG-INFO�rJ )r r rf )�path_mapr� rf rJ r� r/ r/ r0 � get_version` s z!Wheel.update.<locals>.get_versionc S s� d }z|t | �}| �d�}|dk r*d| }nTdd� | |d d � �d�D �}|d d7 < d | d |� d�d d � |D ��f }W n ty� t�d | � Y n0 |r�t|d �}||_|� t �}|j ||d� t�d| |� d S )Nr" r z%s+1c S s g | ] }t |��qS r/ rx )r{ r r/ r/ r0 r} r r7 z8Wheel.update.<locals>.update_version.<locals>.<listcomp>r r$ r� z%s+%sc s s | ]}t |�V qd S r3 )r rz r/ r/ r0 � <genexpr>u r7 z7Wheel.update.<locals>.update_version.<locals>.<genexpr>z0Cannot update non-compliant (PEP-440) version %rr7 )rJ �legacyz Version updated from %r to %r) r r� rk r- r r� r� r rf r� r r� )rf rJ �updatedrG r| r.

The detect_encoding() function is used to detect the encoding that should be used to decode a Python source file. It requires one argument, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised. If the encoding cookie is an invalid charset, raise a SyntaxError. Note that if a utf-8 bom is found, 'utf-8-sig' is returned. If no encoding is specified, then the default of 'utf-8' will be returned.

The dependency relationships are stored in an ``adjacency_list`` that maps distributions to a list of ``(other, label)`` tuples where ``other`` is a distribution and the edge is labeled with ``label`` (i.e. the version specifier, if such was provided). Also, for more efficient traversal, for every distribution ``x``, a list of predecessors is kept in ``reverse_list[x]``. An edge from distribution ``a`` to distribution ``b`` means that ``a`` depends on ``b``. If any missing dependencies are found, they are stored in ``missing``, which is a dictionary that maps distributions to a list of requirements that were not provided by any other distributions. c C s i | _ i | _i | _d S r9 )�adjacency_list� reverse_listr� r! r# r# r$ r% I s zDependencyGraph.__init__c C s g | j |< g | j|< dS )z�Add the *distribution* to the graph. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` N)r r )r" � distributionr# r# r$ �add_distributionN s z DependencyGraph.add_distributionNc C s6 | j | �||f� || j| vr2| j| �|� dS )a� Add an edge from distribution *x* to distribution *y* with the given *label*. :type x: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type y: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type label: ``str`` or ``None`` N)r r) r )r" �x�y�labelr# r# r$ �add_edgeX s zDependencyGraph.add_edgec C s& t �d||� | j�|g ��|� dS )a Add a missing *requirement* for the given *distribution*. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type requirement: ``str`` z %s missing %rN)rS rT r� r' r) )r" r r� r# r# r$ � add_missingg s zDependencyGraph.add_missingc C s d|j |jf S r� r� r* r# r# r$ � _repr_distr s zDependencyGraph._repr_distr c C s� | � |�g}| j| D ]h\}}| � |�}|dur<d||f }|�d| t|� � | �||d �}|�d�}|�|dd� � qd�|�S )zPrints only a subgraphNz%s [%s]z r r� )r% r r) r� � repr_noder� �extendrO )r" r+ �level�outputr� r" Z suboutputZsubsr# r# r$ r& u s zDependencyGraph.repr_nodeTc C s� g }|� d� | j�� D ]h\}}t|�dkr:|s:|�|� |D ]@\}}|durh|� d|j|j|f � q>|� d|j|jf � q>q|s�t|�dkr�|� d� |� d� |� d� |D ] }|� d |j � |� d � q�|� d � |� d � dS ) a9 Writes a DOT output for the graph to the provided file *f*.

If you have a version string that isn't rational (i.e. NormalizedVersion doesn't like it) then you might be able to get an equivalent (or close) rational version from this function. This does a number of simple normalizations to the given string, based on observation of versions currently in use on PyPI. Given a dump of those version during PyCon 2009, 4287 of them: - 2312 (53.93%) match NormalizedVersion without change with the automatic suggestion - 3474 (81.04%) match when using this suggestion method @param s {str} An irrational version string. @returns A rational version string, or None, if couldn't determine one. ))z-alpharp )z-betar� )r� rp )r� r� )r� r< )z-finalr� )z-prer< )z-releaser� )z.releaser� )z-stabler� )r� rg )rr rg )� r� )z.finalr� )rs r� zpre$Zpre0zdev$Zdev0z([abc]|rc)[\-\.](\d+)$z\1\2z[\-\.](dev)[\-\.]?r?(\d+)$z.\1\2z[.~]?([abc])\.?r� r; r Nz\b0+(\d+)(?!\d)z (\d+[abc])$z\g<1>0z\.?(dev-r|dev\.r)\.?(\d+)$z.dev\2z-(a|b|c)(\d+)$z[\.\-](dev|devel)$z.dev0z(?![\.\-])dev$z(final|stable)$r� z\.?(r|-|-r)\.?(\d+)$z.post\2z\.?(dev|git|bzr)\.?(\d+)$z\.?(pre|preview|-c)(\d+)$zc\g<2>zp(\d+)$z.post\1)r~ r rL �replace�rer� r� )r ZrsZorigr� r r r �_suggest_normalized_version� s> r� z([a-z]+|\d+|[\.-])r< zfinal-�@)ry Zpreviewr� r� rz r� rg c C sr dd� }g }|| �D ]T}|� d�r^|dk rD|rD|d dkrD|�� q*|r^|d dkr^|�� qD|�|� qt|�S )Nc S st g }t �| �� �D ]R}t�||�}|rd|d d� krBdkrRn n |�d�}nd| }|�|� q|�d� |S )N�0r �9� �*�*final)� _VERSION_PARTrv rL �_VERSION_REPLACErW �zfillrP )r r` r= r r r � get_partsC s z _legacy_key.<locals>.get_partsr� r� rh z*final-Z00000000)r� �poprP rQ )r r� r` r= r r r � _legacy_keyB s r� c @ s e Zd Zdd� Zedd� �ZdS )r c C s t |�S r )r� r r r r r ] s zLegacyVersion.parsec C s8 d}| j D ](}t|t�r |�d�r |dk r d} q4q |S )NFr� r� T)r rU r r� )r r` r� r r r r7 ` s �zLegacyVersion.is_prereleaseN�r r r r r8 r7 r r r r r \ s r c @ s4 e Zd ZeZeej�Zded< e� d�Z dd� Z dS )r r� rF z^(\d+(\.\d+)*)c C s` ||k r dS | j �t|��}|s2t�d||� dS |�� d }d|v rV|�dd�d }t||�S )NFzACannot compute compatible match for version %s and constraint %sTr rg r )� numeric_rer^ r� �loggerZwarningru �rsplitr� )r rY r[ rT rx r r r r r� s s � z LegacyMatcher._match_compatibleN) r r r r rI �dictr9 rV r� �compiler� r� r r r r r k s r zN^(\d+)\.(\d+)\.(\d+)(-[a-z0-9]+(\.[a-z0-9-]+)*)?(\+[a-z0-9]+(\.[a-z0-9-]+)*)?$c C s t �| �S r )� _SEMVER_REr^ )r r r r r� � s r� c C sn dd� }t | �}|s t| ��|�� }dd� |d d� D �\}}}||d d�||d d� }}|||f||fS ) Nc S s8 | d u r|f}n$| dd � � d�}tdd� |D ��}|S )Nr rg c S s" g | ]}|� � r|�d �n|�qS )r� )rw r� )re r= r r r r� � r?

In the simple case (on Windows, or a shebang line which is not too long or contains spaces) use a simple formulation for the shebang. Otherwise, use /bin/sh as the executable, with a contrived shebang which allows the script to run either under Python or sh, using suitable quoting. Thanks to Harald Nordgren for his input.

If you have a version string that isn't rational (i.e. NormalizedVersion doesn't like it) then you might be able to get an equivalent (or close) rational version from this function. This does a number of simple normalizations to the given string, based on observation of versions currently in use on PyPI. Given a dump of those version during PyCon 2009, 4287 of them: - 2312 (53.93%) match NormalizedVersion without change with the automatic suggestion - 3474 (81.04%) match when using this suggestion

The detect_encoding() function is used to detect the encoding that should be used to decode a Python source file. It requires one argument, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised. If the encoding cookie is an invalid charset, raise a SyntaxError. Note that if a utf-8 bom is found, 'utf-8-sig' is returned. If no encoding is specified, then the default of 'utf-8' will be returned.

The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. If the file pointed by the symlink doesn't exist, an exception will be added in the list of errors raised in an Error exception at the end of the copy process. You can set the optional ignore_dangling_symlinks flag to true if you want to silence this exception. Notice that this has no effect on platforms that don't support os.symlink. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied. It returns a list of names relative to the `src` directory that should not be copied. The optional copy_function argument is a callable that will be used to copy each file. It will be called with the source path and the destination path as arguments. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used.

If ignore_errors is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func, path, exc_info) where func is os.listdir, os.remove, or os.rmdir; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info().

This is similar to the Unix "mv" command. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. A lot more could be done here... A look at a mv.c shows a lot of the issues this implementation glosses over.

The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. If the file pointed by the symlink doesn't exist, an exception will be added in the list of errors raised in an Error exception at the end of the copy process. You can set the optional ignore_dangling_symlinks flag to true if you want to silence this exception. Notice that this has no effect on platforms that don't support os.symlink. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied. It returns a list of names relative to the `src` directory that should not be copied. The optional copy_function argument is a callable that will be used to copy each file. It will be called with the source path and the destination path as arguments. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used.

If ignore_errors is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func, path, exc_info) where func is os.listdir, os.remove, or os.rmdir; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info().

This is similar to the Unix "mv" command. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. A lot more could be done here... A look at a mv.c shows a lot of the issues this implementation glosses over.

HTMLSerializer :arg inject_meta_charset: Whether or not to inject the meta charset. Defaults to ``True``. :arg quote_attr_values: Whether to quote attribute values that don't require quoting per legacy browser behavior (``"legacy"``), when required by the standard (``"spec"``), or always (``"always"``). Defaults to ``"legacy"``. :arg quote_char: Use given quote character for attribute quoting. Defaults to ``"`` which will use double quotes unless attribute value contains a double quote, in which case single quotes are used. :arg escape_lt_in_attrs: Whether or not to escape ``<`` in attribute values. Defaults to ``False``. :arg escape_rcdata: Whether to escape characters that need to be escaped within normal elements within rcdata elements such as style. Defaults to ``False``. :arg resolve_entities: Whether to resolve named character entities that appear in the source tree. The XML predefined entities < > & " ' are unaffected by this setting. Defaults to ``True``. :arg strip_whitespace: Whether to remove semantically meaningless whitespace. (This compresses all whitespace to a single space except within ``pre``.) Defaults to ``False``. :arg minimize_boolean_attributes: Shortens boolean attributes to give just the attribute value, for example:: <input disabled="disabled"> becomes:: <input disabled> Defaults to ``True``. :arg use_trailing_solidus: Includes a close-tag slash at the end of the start tag of void elements (empty elements whose end tag is forbidden). E.g. ``<hr/>``. Defaults to ``False``. :arg space_before_trailing_solidus: Places a space immediately before the closing slash in a tag using a trailing solidus. E.g. ``<hr />``. Requires ``use_trailing_solidus=True``. Defaults to ``True``. :arg sanitize: Strip all unsafe or unknown constructs from output. See :py:class:`html5lib.filters.sanitizer.Filter`.

To create a treebuilder for a new type of tree, you need to do implement several things: 1. A set of classes for various types of elements: Document, Doctype, Comment, Element. These must implement the interface of ``base.treebuilders.Node`` (although comment nodes have a different signature for their constructor, see ``treebuilders.etree.Comment``) Textual content may also be implemented as another node type, or not, as your tree implementation requires. 2. A treebuilder object (called ``TreeBuilder`` by convention) that inherits from ``treebuilders.base.TreeBuilder``. This has 4 required attributes: * ``documentClass`` - the class to use for the bottommost node of a document * ``elementClass`` - the class to use for HTML Elements * ``commentClass`` - the class to use for comments * ``doctypeClass`` - the class to use for doctypes It also has one required method: * ``getDocument`` - Returns the root node of the complete document tree 3. If you wish to run the unit tests, you must also create a ``testSerializer`` method on your treebuilder which accepts a node and returns a string containing Node and its children serialized according to the format used in the unittests � )�absolute_import�division�unicode_literals� )� default_etreeNc K s� | � � } | tvr�| dkrPddlm} |du r<ddlm} |}|j|fi |��jS | dkrpddlm} |jt| < n@| d kr�dd lm } |du r�t }|j |fi |��jS t d | ��t� | �S ) a Get a TreeBuilder class for various types of trees with built-in support :arg treeType: the name of the tree type required (case-insensitive). Supported values are: * "dom" - A generic builder for DOM implementations, defaulting to a xml.dom.minidom based implementation. * "etree" - A generic builder for tree implementations exposing an ElementTree-like interface, defaulting to xml.etree.cElementTree if available and xml.etree.ElementTree if not. * "lxml" - A etree-based builder for lxml.etree, handling limitations of lxml's implementation. :arg implementation: (Currently applies to the "etree" and "dom" tree types). A module implementing the tree type e.g. xml.etree.ElementTree or xml.etree.cElementTree. :arg kwargs: Any additional options to pass to the TreeBuilder when creating it.

To create a treebuilder for a new type of tree, you need to do implement several things: 1. A set of classes for various types of elements: Document, Doctype, Comment, Element. These must implement the interface of ``base.treebuilders.Node`` (although comment nodes have a different signature for their constructor, see ``treebuilders.etree.Comment``) Textual content may also be implemented as another node type, or not, as your tree implementation requires. 2. A treebuilder object (called ``TreeBuilder`` by convention) that inherits from ``treebuilders.base.TreeBuilder``.

After calling ``feed``, you can check the value of the ``done`` attribute to see if you need to continue feeding the ``UniversalDetector`` more data, or if it has made a prediction (in the ``result`` attribute). .. note:: You should always call ``close`` when you're done feeding in your document if ``done`` is not already ``True``.

)�CodingStateMachinea� A state machine to verify a byte sequence for a particular encoding. For each byte the detector receives, it will feed that byte to every active state machine available, one byte at a time. The state machine changes its state based on its previous state and the byte it receives. There are 3 states in a state machine that are of interest to an auto-detector: START state: This is the state to start with, or a legal byte sequence (i.e. a valid code point) for character has been identified. ME state: This indicates that the state machine identified a byte sequence that is specific to the charset it is designed for and that there is no other possible encoding which can contain this byte sequence. This will to lead to an immediate positive answer for the detector. ERROR state: This indicates the state machine identified an illegal byte sequence for that encoding. This will lead to an immediate negative answer for this encoding. Detector will exclude this encoding from consideration from here on. c C s0 || _ d| _d| _d | _t�t�| _| �� d S )Nr ) �_model�_curr_byte_pos�_curr_char_len� _curr_state�loggingZ

international characters [-ÿ] marker: everything else [^a-zA-Z-ÿ] The input buffer can be thought to contain a series of words delimited by markers. This function works to filter all words that contain at least one international character. All contiguous sequences of markers are replaced by a single space ascii character.

Zdd� Zdd � Zd d � Ze d d � �Z dS )�CodingStateMachinea� A state machine to verify a byte sequence for a particular encoding. For each byte the detector receives, it will feed that byte to every active state machine available, one byte at a time. The state machine changes its state based on its previous state and the byte it receives. There are 3 states in a state machine that are of interest to an auto-detector: START state: This is the state to start with, or a legal byte sequence (i.e. a valid code point) for character has been identified. ME state: This indicates that the state machine identified a byte sequence that is specific to the charset it is designed for and that there is no other possible encoding which can contain this byte sequence. This will to lead to an immediate positive answer for the detector. ERROR state: This indicates the state machine identified an illegal byte sequence for that encoding. This will lead to an immediate negative answer for this encoding. Detector will exclude this encoding from consideration from here on. c C s0 || _ d| _d| _d | _t�t�| _| �� d S )Nr ) �_model�_curr_byte_pos�_curr_char_len� _curr_state�loggingZ

Logical Hebrew ?? # # Both "ISO" charsets use a completely identical set of code points, whereas # "windows-1255" and "x-mac-hebrew" are two different proper supersets of # these code points. windows-1255 defines additional characters in the range # 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific # diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. # x-mac-hebrew defines similar additional code points but with a different # mapping. # # As far as an average Hebrew text with no diacritics is concerned, all four # charsets are identical with respect to code points. Meaning that for the # main Hebrew alphabet, all four map the same values to all 27 Hebrew letters # (including final letters). # # The dominant difference between these charsets is their directionality. # "Visual" directionality means that the text is ordered as if the renderer is # not aware of a BIDI rendering algorithm. The renderer sees the text and # draws it from left to right. The text itself when ordered naturally is read # backwards. A buffer of Visual Hebrew generally looks like so: # "[last word of first line spelled backwards] [whole line ordered backwards # and spelled backwards] [first word of first line spelled backwards] # [end of line] [last word of second line] ... etc' " # adding punctuation marks, numbers and English text to visual text is # naturally also "visual" and from left to right. # # "Logical" directionality means the text is ordered "naturally" according to # the order it is read. It is the responsibility of the renderer to display # the text from right to left. A BIDI algorithm is used to place general # punctuation marks, numbers and English text in the text. # # Texts in x-mac-hebrew are almost impossible to find on the Internet. From # what little evidence I could find, it seems that its general directionality # is Logical. # # To sum up all of the above, the Hebrew probing mechanism knows about two # charsets: # Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are # backwards while line order is natural. For charset recognition purposes # the line order is unimportant (In fact, for this implementation, even # word order is unimportant). # Logical Hebrew - "windows-1255" - normal, naturally ordered text. # # "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be # specifically identified. # "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew # that contain special punctuation marks or diacritics is displayed with # some unconverted characters showing as question marks. This problem might # be corrected using another model prober for x-mac-hebrew. Due to the fact # that x-mac-hebrew texts are so rare, writing another model prober isn't # worth the effort and performance hit. # #### The Prober #### # # The prober is divided between two SBCharSetProbers and a HebrewProber, # all of which are managed, created, fed data, inquired and deleted by the # SBCSGroupProber. The two SBCharSetProbers identify that the text is in # fact some kind of Hebrew, Logical or Visual. The final decision about which # one is it is made by the HebrewProber by combining final-letter scores # with the scores of the two SBCharSetProbers to produce a final answer. # # The SBCSGroupProber is responsible for stripping the original text of HTML # tags, English characters, numbers, low-ASCII punctuation characters, spaces # and new lines. It reduces any sequence of such characters to a single space. # The buffer fed to each prober in the SBCS group prober is pure text in # high-ASCII. # The two SBCharSetProbers (model probers) share the same language model: # Win1255Model. # The first SBCharSetProber uses the model normally as any other # SBCharSetProber does, to recognize windows-1255, upon which this model was # built. The second SBCharSetProber is told to make the pair-of-letter # lookup in the language model backwards. This in practice exactly simulates # a visual Hebrew model using the windows-1255 logical Hebrew model. # # The HebrewProber is not using any language model. All it does is look for # final-letter evidence suggesting the text is either logical Hebrew or visual # Hebrew. Disjointed from the model probers, the results of the HebrewProber # alone are meaningless. HebrewProber always returns 0.00 as confidence # since it never identifies a charset by itself. Instead, the pointer to the # HebrewProber is passed to the model probers as a helper "Name Prober". # When the Group prober receives a positive identification from any prober, # it asks for the name of the charset identified. If the prober queried is a # Hebrew model prober, the model prober forwards the call to the # HebrewProber to make the final decision. In the HebrewProber, the # decision is made according to the final-letters scores maintained and Both # model probers scores.

When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place. chunk_size must be of type int or None. A value of None will function differently depending on the value of `stream`. stream=True will read data as it arrives in whatever size the chunks are received. If stream=False, data is returned as a single chunk. If decode_unicode is True, content will be decoded using the best available encoding based on the response. c 3 s� t �jd�r�z �jj� dd�D ] } | V q W q� tyX } zt|��W Y d }~q�d }~0 ty� } zt|��W Y d }~q�d }~0 ty� } zt|��W Y d }~q�d }~0 0 n�j� � �} | s�q�| V q�d�_ d S )N�streamT)Zdecode_content) rG r� r� r r r r r r rB r� )�chunkr� �� chunk_sizer= r? r@ �generate� s z'Response.iter_content.<locals>.generateNz.chunk_size must be an int, it is instead a %s.) r� rF r� �boolr �intr� �typer! r )r= r� �decode_unicoder� Z reused_chunksZ stream_chunks�chunksr? r� r@ r� � s zResponse.iter_contentNc c s� d}| j ||d�D ]n}|dur&|| }|r6|�|�}n|�� }|rl|d rl|rl|d d |d krl|�� }nd}|D ] }|V qtq|dur�|V dS )z�Iterates over the response data, one line at a time.

A value of None will function differently depending on the value of `stream`. stream=True will read data as it arrives in whatever size the chunks are received.

Implements all methods and operations of ``MutableMapping`` as well as dict's ``copy``. Also provides ``lower_items``. All keys are expected to be strings. The structure remembers the case of the last key to be set, and ``iter(instance)``, ``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()`` will contain case-sensitive keys. However, querying and contains testing is case insensitive:: cid = CaseInsensitiveDict() cid['Accept'] = 'application/json' cid['aCCEPT'] == 'application/json' # True list(cid) == ['Accept'] # True For example, ``headers['content-encoding']`` will return the value of a ``'Content-Encoding'`` response header, regardless of how the header name was originally stored. If the constructor, ``.update``, or equality comparison operations are given keys that have equal ``.lower()``s, the behavior is undefined.

The structure remembers the case of the last key to be set, and ``iter(instance)``, ``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()`` will contain case-sensitive keys. However, querying and contains testing is case insensitive:: cid = CaseInsensitiveDict() cid['Accept'] = 'application/json' cid['aCCEPT'] == 'application/json' # True list(cid) == ['Accept'] # True For example, ``headers['content-encoding']`` will return the value of a ``'Content-Encoding'`` response header, regardless of how the header name was originally stored.

With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python. Here is a program to parse "Hello, World!" (or any greeting of the form ``"<salutation>, <addressee>!"``), built up using :class:`Word`, :class:`Literal`, and :class:`And` elements (the :class:`'+'<ParserElement.__add__>` operators create :class:`And` expressions, and the strings are auto-converted to :class:`Literal` expressions):: from pip._vendor.pyparsing import Word, alphas # define grammar of a greeting greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print (hello, "->", greet.parseString(hello)) The program outputs the following:: Hello, World! -> ['Hello', ',', 'World', '!'] The Python representation of the grammar is quite readable, owing to the self-explanatory class names, and the use of '+', '|' and '^' operators. The :class:`ParseResults` object returned from :class:`ParserElement.parseString` can be accessed as a nested list, a dictionary, or an object with named attributes. The pyparsing module handles some of the problems that are typically vexing when writing text parsers: - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.) - quoted strings - embedded comments Getting Started - ----------------- Visit the classes :class:`ParserElement` and :class:`ParseResults` to see the base classes that most other pyparsing classes inherit from. Use the docstrings for examples of how to: - construct literal match expressions from :class:`Literal` and :class:`CaselessLiteral` classes - construct character word-group expressions using the :class:`Word` class - see how to create repetitive expressions using :class:`ZeroOrMore` and :class:`OneOrMore` classes - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`, and :class:`'&'<Each>` operators to combine simple expressions into more complex ones - associate names with your parsed results using :class:`ParserElement.setResultsName` - access the parsed data, which is returned as a :class:`ParseResults` object - find some helpful expression short-cuts like :class:`delimitedList` and :class:`oneOf` - find more useful common expressions in the :class:`pyparsing_common` namespace class """ __version__ = "2.4.7" __versionTime__ = "30 Mar 2020 00:43 UTC" __author__ = "Paul McGuire <ptmcg@users.sourceforge.net>" import string from weakref import ref as wkref import copy import sys import warnings import re import sre_constants import collections import pprint import traceback import types from datetime import datetime from operator import itemgetter import itertools from functools import wraps from contextlib import contextmanager try: # Python 3 from itertools import filterfalse except ImportError: from itertools import ifilterfalse as filterfalse try: from _thread import RLock except ImportError: from threading import RLock try: # Python 3 from collections.abc import Iterable from collections.abc import MutableMapping, Mapping except ImportError: # Python 2.7 from collections import Iterable from collections import MutableMapping, Mapping try: from collections import OrderedDict as _OrderedDict except ImportError: try: from ordereddict import OrderedDict as _OrderedDict except ImportError: _OrderedDict = None try: from types import SimpleNamespace except ImportError: class SimpleNamespace: pass # version compatibility configuration __compat__ = SimpleNamespace() __compat__.__doc__ = """ A cross-version compatibility configuration for pyparsing features that will be released in a future version.

However, MSYS2 incorrectly patches sysconfig ``nt`` scheme. The fix is likely going to be included in their 3.10 release, so we ignore the warning. See msys2/MINGW-packages#9319. MSYS2 MINGW's patch uses lowercase ``"lib"`` instead of the usual uppercase, and is missing the final ``"site-packages"``. �ntF)�expandc s s* | ]"}d |vo d|v o |� d� V qdS )ZLibr z site-packagesN)�endswith)r4 �pr' r' r( r6 � s �z1_looks_like_msys2_mingw_scheme.<locals>.<genexpr>c 3 s | ]}� | V qd S r2 r' )r4 �key��pathsr' r( r6 � � �r$ r, )� sysconfigZ get_pathsr7 r' r' rH r( � _looks_like_msys2_mingw_schemev s �rM )�partsr! c c sh t �d�}ttdd �}|r(|r(|�|�s6| E d H d S | D ](}|�|�r\|d dt|� � }|V q:d S )NZ LDVERSION�abiflagsr )rL Zget_config_var�getattrr. rE �len)rN Z ldversionrO �partr' r' r( � _fix_abiflags� s rS )�old�newrG r! c C s d}d}t �t|||| |� d S )Nz(https://github.com/pypa/pip/issues/10151zSValue for %s does not match.

Debian's ``distutils.sysconfig.get_python_lib()`` implementation returns the default package path controlled by APT, but does not patch ``sysconfig`` to do the same. This is similar to the bug worked around in ``get_scheme()``, but here the default is ``deb_system`` instead of ``unix_local``. Ultimately we can't do anything about this Debian bug, and this detection allows us to skip the warning when needed.

Python distributed by Apple's Command Line Tools has this special scheme that's used when: * This is a framework build. * We are installing into the system prefix. This does not account for ``pip install --prefix`` (also means we're not installing to the system prefix), which should use ``posix_prefix``, but logic here means ``_infer_prefix()`` outputs ``osx_framework_library``. But since ``prefix`` is not available for ``sysconfig.get_default_scheme()``, which is the stdlib replacement for ``_infer_prefix()``, presumably Apple wouldn't be able to magically switch between ``osx_framework_library`` and ``posix_prefix``. ``_infer_prefix()`` returning ``osx_framework_library`` means its behavior is consistent whether we use the stdlib implementation or our own, and we deal with this special case in ``get_scheme()`` instead. �osx_framework_library)�_AVAILABLE_SCHEMESr r � r r �F/usr/lib/python3.9/site-packages/pip/_internal/locations/_sysconfig.py� _should_use_osx_framework_prefix s ��r c C sv t r t d�S t� rdS tjj� dtj� �} | tv r6| S tjjtv rJtjjS tj� d�}|tv rb|S tjtv rrtjS dS )a!

Debian's ``distutils.sysconfig.get_python_lib()`` implementation returns the default package path controlled by APT, but does not patch ``sysconfig`` to do the same. This is similar to the bug worked around in ``get_scheme()``, but here the default is ``deb_system`` instead of ``unix_local``. Ultimately we can't do anything about this Debian bug, and this detection allows us to skip the warning when needed.
