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. i(tabsolute_importN(t get_importer(tsix(turllibtmaptfilter(tutime(tmkdirtrenametunlink(topen(tisdirtspliti(t py31compat(tappdirs(t packagings&pkg_resources.extern.packaging.versions)pkg_resources.extern.packaging.specifierss+pkg_resources.extern.packaging.requirementss&pkg_resources.extern.packaging.markersisPython 3.3 or later is requiredt PEP440WarningcB@seZdZRS(sa Used when there is an issue with a version or specifier not complying with PEP 440.

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. i(tabsolute_importN(t get_importer(tsix(turllibtmaptfilter(tutime(tmkdirtrenametunlink(topen(tisdirtspliti(t py31compat(tappdirs(t packagings&pkg_resources.extern.packaging.versions)pkg_resources.extern.packaging.specifierss+pkg_resources.extern.packaging.requirementss&pkg_resources.extern.packaging.markersisPython 3.3 or later is requiredt PEP440WarningcB@seZdZRS(sa Used when there is an issue with a version or specifier not complying with PEP 440.

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 C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from 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 L{ParseResults} object returned from L{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 s2.1.10s07 Oct 2016 01:31 UTCs*Paul McGuire iN(tref(tdatetime(tRLock(t OrderedDicttAndtCaselessKeywordtCaselessLiteralt CharsNotIntCombinetDicttEachtEmptyt FollowedBytForwardt GoToColumntGrouptKeywordtLineEndt LineStarttLiteralt MatchFirsttNoMatchtNotAnyt OneOrMoretOnlyOncetOptionaltOrtParseBaseExceptiontParseElementEnhancetParseExceptiontParseExpressiontParseFatalExceptiont ParseResultstParseSyntaxExceptiont ParserElementt QuotedStringtRecursiveGrammarExceptiontRegextSkipTot StringEndt StringStarttSuppresstTokentTokenConvertertWhitetWordtWordEndt WordStartt ZeroOrMoret alphanumstalphast alphas8bitt anyCloseTagt anyOpenTagt cStyleCommenttcoltcommaSeparatedListtcommonHTMLEntityt countedArraytcppStyleCommenttdblQuotedStringtdblSlashCommentt delimitedListtdictOftdowncaseTokenstemptythexnumst htmlCommenttjavaStyleCommenttlinetlineEndt lineStarttlinenot makeHTMLTagst makeXMLTagstmatchOnlyAtColtmatchPreviousExprtmatchPreviousLiteralt nestedExprtnullDebugActiontnumstoneOftopAssoctoperatorPrecedencet printablestpunc8bittpythonStyleCommentt quotedStringt removeQuotestreplaceHTMLEntityt replaceWitht restOfLinetsglQuotedStringtsranget stringEndt stringStartttraceParseActiont unicodeStringt upcaseTokenst withAttributet indentedBlocktoriginalTextFortungroupt infixNotationt locatedExprt withClasst CloseMatchttokenMaptpyparsing_commoniicCs}t|tr|Syt|SWnUtk rxt|jtjd}td}|jd|j |SXdS(sDrop-in replacement for str(obj) that tries to be Unicode friendly.

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 C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{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 L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{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=",") iicstt|jrcdjfd|D}|rcdjfd|D}qcn||_t||_|r||_t||_n||_t||_|dk|_ |dkrt dn||_ |dkr||_ n t |_ |dkr)||_ ||_ nt||_d|j|_t|_||_d|j|jkr}|dkr}|dkr}|dkr}|j|jkrd t|j|_net|jdkrd tj|jt|jf|_n%d t|jt|jf|_|jrDd |jd |_nytj|j|_Wq}tk ryd|_q}XndS( NRrc3s!|]}|kr|VqdS(N((RR(t excludeChars(sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys 7 sc3s!|]}|kr|VqdS(N((RR(R<(sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys 9 siisZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permitteds Expected Rs[%s]+s%s[%s]*s [%s][%s]*s\b(R R-RRt initCharsOrigRt initCharst bodyCharsOrigt bodyCharst maxSpecifiedRtminLentmaxLenR$RRRyRRxt asKeywordt_escapeRegexRangeCharstreStringRR|tescapetcompileRaR(RR>R@tmintmaxtexactRDR<((R<sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR4 sT%             :   c Cs|jr[|jj||}|s?t|||j|n|j}||jfS|||jkrt|||j|n|}|d7}t|}|j}||j }t ||}x*||kr|||kr|d7}qWt } |||j krt } n|jrG||krG|||krGt } n|jr|dkrp||d|ks||kr|||krt } qn| rt|||j|n||||!fS(Nii(R|R%RRytendtgroupR>RR@RCRIRRBRRARD( RRERRR!R5Rt bodycharsR6tthrowException((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRj s6       %  < cCsytt|jSWntk r*nX|jdkrd}|j|jkr}d||j||jf|_qd||j|_n|jS(NcSs&t|dkr|d dS|SdS(Nis...(R(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyt charsAsStr s s W:(%s,%s)sW:(%s)(R R-RRaRmRR=R?(RRP((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  (N( RRRRRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR- s.6 #cBsDeZdZeejdZddZedZ dZ RS(s Token for matching strings that match a given regular expression.

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 L{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 C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{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]]] iis%s terms %s%s termis@if numterms=3, opExpr must be a tuple or list of two expressionsis6operator must be unary (1), binary (2), or ternary (3)s2operator must indicate right or left associativityN(N(R RRRRRRRtLEFTR RRtRIGHTRsRRFRz(tbaseExprtopListtlpartrparR}tlastExprRtoperDeftopExprtaritytrightLeftAssocRttermNametopExpr1topExpr2tthisExprR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRgsR;    '  /'   $  /'     s4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*t"s string enclosed in double quotess4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*t's string enclosed in single quotess*quotedString using single or double quotestusunicode string literalcCs!||krtdn|d krt|trt|trt|dkrt|dkr|d k rtt|t||tj ddj d}q|t j t||tj j d}q|d k r9tt|t |t |ttj ddj d}qttt |t |ttj ddj d}qtdnt}|d k r|tt|t||B|Bt|K}n.|tt|t||Bt|K}|jd ||f|S( s~ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default).

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 C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from 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 L{ParseResults} object returned from L{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 """ __version__ = "2.1.10" __versionTime__ = "07 Oct 2016 01:31 UTC" __author__ = "Paul McGuire " 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 try: from _thread import RLock except ImportError: from threading import RLock try: from collections import OrderedDict as _OrderedDict except ImportError: try: from ordereddict import OrderedDict as _OrderedDict except ImportError: _OrderedDict = None #~ sys.stderr.write( "testing pyparsing module, version %s, %s\n" % (__version__,__versionTime__ ) ) __all__ = [ 'And', 'CaselessKeyword', 'CaselessLiteral', 'CharsNotIn', 'Combine', 'Dict', 'Each', 'Empty', 'FollowedBy', 'Forward', 'GoToColumn', 'Group', 'Keyword', 'LineEnd', 'LineStart', 'Literal', 'MatchFirst', 'NoMatch', 'NotAny', 'OneOrMore', 'OnlyOnce', 'Optional', 'Or', 'ParseBaseException', 'ParseElementEnhance', 'ParseException', 'ParseExpression', 'ParseFatalException', 'ParseResults', 'ParseSyntaxException', 'ParserElement', 'QuotedString', 'RecursiveGrammarException', 'Regex', 'SkipTo', 'StringEnd', 'StringStart', 'Suppress', 'Token', 'TokenConverter', 'White', 'Word', 'WordEnd', 'WordStart', 'ZeroOrMore', 'alphanums', 'alphas', 'alphas8bit', 'anyCloseTag', 'anyOpenTag', 'cStyleComment', 'col', 'commaSeparatedList', 'commonHTMLEntity', 'countedArray', 'cppStyleComment', 'dblQuotedString', 'dblSlashComment', 'delimitedList', 'dictOf', 'downcaseTokens', 'empty', 'hexnums', 'htmlComment', 'javaStyleComment', 'line', 'lineEnd', 'lineStart', 'lineno', 'makeHTMLTags', 'makeXMLTags', 'matchOnlyAtCol', 'matchPreviousExpr', 'matchPreviousLiteral', 'nestedExpr', 'nullDebugAction', 'nums', 'oneOf', 'opAssoc', 'operatorPrecedence', 'printables', 'punc8bit', 'pythonStyleComment', 'quotedString', 'removeQuotes', 'replaceHTMLEntity', 'replaceWith', 'restOfLine', 'sglQuotedString', 'srange', 'stringEnd', 'stringStart', 'traceParseAction', 'unicodeString', 'upcaseTokens', 'withAttribute', 'indentedBlock', 'originalTextFor', 'ungroup', 'infixNotation','locatedExpr', 'withClass', 'CloseMatch', 'tokenMap', 'pyparsing_common', ] system_version = tuple(sys.version_info)[:3] PY_3 = system_version[0] == 3 if PY_3: _MAX_INT = sys.maxsize basestring = str unichr = chr _ustr = str # build list of single arg builtins, that can be used as parse actions singleArgBuiltins = [sum, len, sorted, reversed, list, tuple, set, any, all, min, max] else: _MAX_INT = sys.maxint range = xrange def _ustr(obj): """Drop-in replacement for str(obj) that tries to be Unicode friendly.

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 C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{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]]] """ ret = Forward() lastExpr = baseExpr | ( lpar + ret + rpar ) for i,operDef in enumerate(opList): opExpr,arity,rightLeftAssoc,pa = (operDef + (None,))[:4] termName = "%s term" % opExpr if arity < 3 else "%s%s term" % opExpr if arity == 3: if opExpr is None or len(opExpr) != 2: raise ValueError("if numterms=3, opExpr must be a tuple or list of two expressions") opExpr1, opExpr2 = opExpr thisExpr = Forward().setName(termName) if rightLeftAssoc == opAssoc.LEFT: if arity == 1: matchExpr = FollowedBy(lastExpr + opExpr) + Group( lastExpr + OneOrMore( opExpr ) ) elif arity == 2: if opExpr is not None: matchExpr = FollowedBy(lastExpr + opExpr + lastExpr) + Group( lastExpr + OneOrMore( opExpr + lastExpr ) ) else: matchExpr = FollowedBy(lastExpr+lastExpr) + Group( lastExpr + OneOrMore(lastExpr) ) elif arity == 3: matchExpr = FollowedBy(lastExpr + opExpr1 + lastExpr + opExpr2 + lastExpr) + \ Group( lastExpr + opExpr1 + lastExpr + opExpr2 + lastExpr ) else: raise ValueError("operator must be unary (1), binary (2), or ternary (3)") elif rightLeftAssoc == opAssoc.RIGHT: if arity == 1: # try to avoid LR with this extra test if not isinstance(opExpr, Optional): opExpr = Optional(opExpr) matchExpr = FollowedBy(opExpr.expr + thisExpr) + Group( opExpr + thisExpr ) elif arity == 2: if opExpr is not None: matchExpr = FollowedBy(lastExpr + opExpr + thisExpr) + Group( lastExpr + OneOrMore( opExpr + thisExpr ) ) else: matchExpr = FollowedBy(lastExpr + thisExpr) + Group( lastExpr + OneOrMore( thisExpr ) ) elif arity == 3: matchExpr = FollowedBy(lastExpr + opExpr1 + thisExpr + opExpr2 + thisExpr) + \ Group( lastExpr + opExpr1 + thisExpr + opExpr2 + thisExpr ) else: raise ValueError("operator must be unary (1), binary (2), or ternary (3)") else: raise ValueError("operator must indicate right or left associativity") if pa: matchExpr.setParseAction( pa ) thisExpr <<= ( matchExpr.setName(termName) | lastExpr ) lastExpr = thisExpr ret <<= lastExpr return ret operatorPrecedence = infixNotation """(Deprecated) Former name of C{L{infixNotation}}, will be dropped in a future release.""" dblQuotedString = Combine(Regex(r'"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*')+'"').setName("string enclosed in double quotes") sglQuotedString = Combine(Regex(r"'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*")+"'").setName("string enclosed in single quotes") quotedString = Combine(Regex(r'"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*')+'"'| Regex(r"'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*")+"'").setName("quotedString using single or double quotes") unicodeString = Combine(_L('u') + quotedString.copy()).setName("unicode string literal") def nestedExpr(opener="(", closer=")", content=None, ignoreExpr=quotedString.copy()): """ Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default).

Classes and methods to define and execute parsing grammars The pyparsing module is an alternative approach to creating and executing simple grammars, vs. the traditional lex/yacc approach, or the use of regular expressions. 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 C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'} operator gives L{And} expressions, strings are auto-converted to L{Literal} expressions):: from 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 L{ParseResults} object returned from L{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 s2.1.10s07 Oct 2016 01:31 UTCs*Paul McGuire iN(tref(tdatetime(tRLock(t OrderedDicttAndtCaselessKeywordtCaselessLiteralt CharsNotIntCombinetDicttEachtEmptyt FollowedBytForwardt GoToColumntGrouptKeywordtLineEndt LineStarttLiteralt MatchFirsttNoMatchtNotAnyt OneOrMoretOnlyOncetOptionaltOrtParseBaseExceptiontParseElementEnhancetParseExceptiontParseExpressiontParseFatalExceptiont ParseResultstParseSyntaxExceptiont ParserElementt QuotedStringtRecursiveGrammarExceptiontRegextSkipTot StringEndt StringStarttSuppresstTokentTokenConvertertWhitetWordtWordEndt WordStartt ZeroOrMoret alphanumstalphast alphas8bitt anyCloseTagt anyOpenTagt cStyleCommenttcoltcommaSeparatedListtcommonHTMLEntityt countedArraytcppStyleCommenttdblQuotedStringtdblSlashCommentt delimitedListtdictOftdowncaseTokenstemptythexnumst htmlCommenttjavaStyleCommenttlinetlineEndt lineStarttlinenot makeHTMLTagst makeXMLTagstmatchOnlyAtColtmatchPreviousExprtmatchPreviousLiteralt nestedExprtnullDebugActiontnumstoneOftopAssoctoperatorPrecedencet printablestpunc8bittpythonStyleCommentt quotedStringt removeQuotestreplaceHTMLEntityt replaceWitht restOfLinetsglQuotedStringtsranget stringEndt stringStartttraceParseActiont unicodeStringt upcaseTokenst withAttributet indentedBlocktoriginalTextFortungroupt infixNotationt locatedExprt withClasst CloseMatchttokenMaptpyparsing_commoniicCs}t|tr|Syt|SWnUtk rxt|jtjd}td}|jd|j |SXdS(sDrop-in replacement for str(obj) that tries to be Unicode friendly.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{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 C{L{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. Optional keyword arguments: - callDuringTry = (default=C{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.

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 C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{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 L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{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=",") iicstt|jrcdjfd|D}|rcdjfd|D}qcn||_t||_|r||_t||_n||_t||_|dk|_ |dkrt dn||_ |dkr||_ n t |_ |dkr)||_ ||_ nt||_d|j|_t|_||_d|j|jkr}|dkr}|dkr}|dkr}|j|jkrd t|j|_net|jdkrd tj|jt|jf|_n%d t|jt|jf|_|jrDd |jd |_nytj|j|_Wq}tk ryd|_q}XndS( NRrc3s!|]}|kr|VqdS(N((RR(t excludeChars(sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys 7 sc3s!|]}|kr|VqdS(N((RR(R<(sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys 9 siisZcannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permitteds Expected Rs[%s]+s%s[%s]*s [%s][%s]*s\b(R R-RRt initCharsOrigRt initCharst bodyCharsOrigt bodyCharst maxSpecifiedRtminLentmaxLenR$RRRyRRxt asKeywordt_escapeRegexRangeCharstreStringRR|tescapetcompileRaR(RR>R@tmintmaxtexactRDR<((R<sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR4 sT%             :   c Cs|jr[|jj||}|s?t|||j|n|j}||jfS|||jkrt|||j|n|}|d7}t|}|j}||j }t ||}x*||kr|||kr|d7}qWt } |||j krt } n|jrG||krG|||krGt } n|jr|dkrp||d|ks||kr|||krt } qn| rt|||j|n||||!fS(Nii(R|R%RRytendtgroupR>RR@RCRIRRBRRARD( RRERRR!R5Rt bodycharsR6tthrowException((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRj s6       %  < cCsytt|jSWntk r*nX|jdkrd}|j|jkr}d||j||jf|_qd||j|_n|jS(NcSs&t|dkr|d dS|SdS(Nis...(R(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyt charsAsStr s s W:(%s,%s)sW:(%s)(R R-RRaRmRR=R?(RRP((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  (N( RRRRRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR- s.6 #cBsDeZdZeejdZddZedZ dZ RS(s Token for matching strings that match a given regular expression.

Also takes optional C{min}, C{max}, and C{exact} arguments, as defined for the C{L{Word}} class. sRss ss ss ss s iicsttj|_jdjfdjDdjdjD_t_ dj_ |_ |dkr|_ n t _ |dkr|_ |_ ndS(NRrc3s$|]}|jkr|VqdS(N(t matchWhite(RR(R(sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys scss|]}tj|VqdS(N(R,t whiteStrs(RR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys ss Expected i(R R,RRmRRRqRRRsRyRBRCR$(RtwsRIRJRK((RsC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s )       cCs|||jkr.t|||j|n|}|d7}||j}t|t|}x-||kr|||jkr|d7}qcW|||jkrt|||j|n||||!fS(Ni(RmRRyRCRIRRB(RRERRR5R6((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  "(RRRRnRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR, s t_PositionTokencBseZdZRS(cCs8tt|j|jj|_t|_t|_ dS(N( R RpRR^RRRRsRRx(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s (RRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRp scBs,eZdZdZdZedZRS(sb Token to advance to a specific column of input text; useful for tabular report scraping. cCs tt|j||_dS(N(R RRR7(Rtcolno((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR scCst|||jkrt|}|jrB|j||}nxE||kr||jrt|||jkr|d7}qEWn|S(Ni(R7RRuRtisspace(RRERR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  7cCs^t||}||jkr6t||d|n||j|}|||!}||fS(NsText not in expected column(R7R(RRERRtthiscoltnewlocR}((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  (RRRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s  cBs#eZdZdZedZRS(s Matches if current position is at the beginning of a line within the parse string Example:: test = ''' AAA this line AAA and this line AAA but not this one B AAA and definitely not this one ''' for t in (LineStart() + 'AAA' + restOfLine).searchString(test): print(t) Prints:: ['AAA', ' this line'] ['AAA', ' and this line'] cCs tt|jd|_dS(NsExpected start of line(R RRRy(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR& scCs;t||dkr|gfSt|||j|dS(Ni(R7RRy(RRERR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR* s (RRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR s cBs#eZdZdZedZRS(sU Matches if current position is at the end of a line within the parse string cCs<tt|j|jtjjddd|_dS(Ns RrsExpected end of line(R RRRR"RfRRy(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR3 scCs|t|krK||dkr0|ddfSt|||j|n8|t|krk|dgfSt|||j|dS(Ns i(RRRy(RRERR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR8 s(RRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR/ s cBs#eZdZdZedZRS(sM Matches if current position is at the beginning of the parse string cCs tt|jd|_dS(NsExpected start of text(R R(RRy(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRG scCsL|dkrB||j|dkrBt|||j|qBn|gfS(Ni(RRRy(RRERR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRK s (RRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR(C s cBs#eZdZdZedZRS(sG Matches if current position is at the end of the parse string cCs tt|jd|_dS(NsExpected end of text(R R'RRy(R((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRV scCs|t|kr-t|||j|nT|t|krM|dgfS|t|kri|gfSt|||j|dS(Ni(RRRy(RRERR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRZ s (RRRRRR(((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR'R s cBs&eZdZedZedZRS(sp Matches if the current position is at the beginning of a Word, and is not preceded by any character in a given set of C{wordChars} (default=C{printables}).

Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{**} operator, when an attribute name is also a Python reserved word, as in C{**{"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 C{class} (with or without a namespace), use C{L{withClass}}.

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 L{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 C{opAssoc.RIGHT} and C{opAssoc.LEFT}. - parseAction is the parse action to be associated with expressions matching this operator expression (the parse action tuple member may be omitted) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{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]]] iis%s terms %s%s termis@if numterms=3, opExpr must be a tuple or list of two expressionsis6operator must be unary (1), binary (2), or ternary (3)s2operator must indicate right or left associativityN(N(R RRRRRRRtLEFTR RRtRIGHTRsRRFRz(tbaseExprtopListtlpartrparR}tlastExprRtoperDeftopExprtaritytrightLeftAssocRttermNametopExpr1topExpr2tthisExprR((sC/usr/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRgsR;    '  /'   $  /'     s4"(?:[^"\n\r\\]|(?:"")|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*t"s string enclosed in double quotess4'(?:[^'\n\r\\]|(?:'')|(?:\\(?:[^x]|x[0-9a-fA-F]+)))*t's string enclosed in single quotess*quotedString using single or double quotestusunicode string literalcCs!||krtdn|d krt|trt|trt|dkrt|dkr|d k rtt|t||tj ddj d}q|t j t||tj j d}q|d k r9tt|t |t |ttj ddj d}qttt |t |ttj ddj d}qtdnt}|d k r|tt|t||B|Bt|K}n.|tt|t||Bt|K}|jd ||f|S( s~ 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=C{"("}); can also be a pyparsing expression - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression - content - expression for items within the nested lists (default=C{None}) - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{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 C{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 C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument.

    Return a directory to store cached wheels in for link.

    Because there are M wheels for any one sdist, we provide a directory
    to cache them in, and then consult that directory when looking up
    cache hits.

    We only insert things into the cache if they have plausible version
    numbers, so that we don't contaminate the cache with things that were not
    unique. E.g. ./package might have dozens of installs done for it and build
    a version of 0.0...and if we built and cached a wheel, we'd end up using
    the same wheel even if the source has been edited.

    :param cache_dir: The cache_dir being used by pip.
    :param link: The link of the sdist for which this will cache wheels.

    # Special case pip and setuptools to generate versioned wrappers

    # The issue is that some projects (specifically, pip and setuptools) use
    # code in setup.py to create "versioned" entry points - pip2.7 on Python
    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
    # the wheel metadata at build time, and so if the wheel is installed with
    # a *different* version of Python the entry points will be wrong. The
    # correct fix for this is to enhance the metadata to be able to describe
    # such versioned entry points, but that won't happen till Metadata 2.0 is
    # available.
    # In the meantime, projects using versioned entry points will either have
    # incorrect versioned entry points, or they will not be able to distribute
    # "universal" wheels (i.e., they will need a wheel per Python version).
    #
    # Because setuptools and pip are bundled with _ensurepip and virtualenv,
    # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
    # override the versioned entry points in the wheel and generate the
    # correct ones. This code is purely a short-term measure until Metadata 2.0
    # is available.

shared options and groups

The principle here is to define options once, but *not* instantiate them
globally. One reason being that options with action='append' can carry state
between parses. pip parses general options twice internally, and shouldn't
pass on state. To be consistent, all options will follow this design.

between parses. pip parses general options twice internally, and shouldn't
pass on state. To be consistent, all options will follow this design.

    Return a directory to store cached wheels in for link.

    Because there are M wheels for any one sdist, we provide a directory
    to cache them in, and then consult that directory when looking up
    cache hits.

    We only insert things into the cache if they have plausible version
    numbers, so that we don't contaminate the cache with things that were not
    unique. E.g. ./package might have dozens of installs done for it and build
    a version of 0.0...and if we built and cached a wheel, we'd end up using
    the same wheel even if the source has been edited.

    :param cache_dir: The cache_dir being used by pip.
    :param link: The link of the sdist for which this will cache wheels.

rdA}nX|S(BsSuggest a normalized version close to the given version string.

    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.

    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.

        Install a wheel to the specified paths. 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.

        The return value is a :class:`InstalledDistribution` instance unless
        ``options.lib_only`` is True, in which case the return value is ``None``.

        This is a convenience method for downloading a file from an URL.
        Normally, this will be a file from the index, though currently
        no check is made for this (i.e. a file can be downloaded from
        anywhere).

        The method is just like the :func:`urlretrieve` function in the
        standard library, except that it allows digest computation to be
        done during download and checking that the downloaded data
        matched any expected value.

        :param url: The URL of the file to be downloaded (assumed to be
                    available via an HTTP GET request).
        :param destfile: The pathname where the downloaded file is to be
                         saved.
        :param digest: If specified, this must be a (hasher, value)
                       tuple, where hasher is the algorithm used (e.g.
                       ``'md5'``) and ``value`` is the expected value.
        :param reporthook: The same as for :func:`urlretrieve` in the

        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.

ZdZdZdZdZdZRS(s A ChainMap groups multiple dicts (or other mappings) together
        to create a single, updateable view.

        The underlying mappings are stored in a list.  That list is public and can
        accessed or updated using the *maps* attribute.  There is no other state.

        Lookups search the underlying mappings successively until a key is found.
        In contrast, writes, updates, and deletions only operate on the first
        mapping.

        cG@st|pig|_dS(sInitialize a ChainMap by setting *maps* to the given mappings.
            If no mappings are provided, a single empty dictionary is used.

    Return the default base location for distlib caches. If the directory does
    not exist, it is created. Use the suffix provided for the base directory,
    and default to '.distlib' if it isn't provided.

    On Windows, if LOCALAPPDATA is defined in the environment, then it is
    assumed to be a directory, and will be the parent directory of the result.
    On POSIX, and on Windows if LOCALAPPDATA is not defined, the user's home
    directory - using os.expanduser('~') - will be the parent directory of
    the result.

    The result is just the directory '.distlib' in the parent directory as
    determined above, or with the name specified with ``suffix``.

            This is called to create a connection instance. Normally you'd
            pass a connection class to do_open, but it doesn't actually check for
            a class, and just expects a callable. As long as we behave just as a
            constructor would have, we should be OK. If it ever changes so that
            we *must* pass a class, we'll create an UnsafeHTTPSConnection class
            which just sets check_domain to False in the class definition, and
            choose which one to pass to do_open.

        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.

ZdZdZdZdZdZRS(s A ChainMap groups multiple dicts (or other mappings) together
        to create a single, updateable view.

        The underlying mappings are stored in a list.  That list is public and can
        accessed or updated using the *maps* attribute.  There is no other state.

        Lookups search the underlying mappings successively until a key is found.
        In contrast, writes, updates, and deletions only operate on the first
        mapping.

    This is used mainly to distinguish platform-specific build directories and
    platform-specific built distributions.  Typically includes the OS name
    and version and the architecture (as supplied by 'os.uname()'),
    although the exact information included depends on the OS; eg. for IRIX
    the architecture isn't particularly important (IRIX only runs on SGI
    hardware), but for Linux the kernel version isn't particularly
    important.

    Examples of returned values:
       linux-i586
       linux-alpha (?)
       solaris-2.6-sun4u
       irix-5.3
       irix64-6.2

    Windows will return one of:
       win-amd64 (64bit Windows on AMD64 (aka x86_64, Intel64, EM64T, etc)
       win-ia64 (64bit Windows on Itanium)
       win32 (all others - specifically, sys.platform is returned)

    For other non-POSIX platforms, currently just returns 'sys.platform'.

|ndS(sRecursively copy a directory tree.

    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.

    path is the argument to that function that caused it to fail; and

    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 stream-like object.  The stream-like object only
       needs to have a read() or write() method and is accessed
       blockwise.  Use of gzip or bzip2 compression is possible.
       A stream-like object could be for example: sys.stdin,
       sys.stdout, a socket, a tape device etc.

|ndS(sRecursively copy a directory tree.

    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 the destination already exists but is not a directory, it may be

    If the destination is on our current filesystem, then rename() is used.

    hardware), but for Linux the kernel version isn't particularly
    important.

       win-ia64 (64bit Windows on Itanium)
       win32 (all others - specifically, sys.platform is returned)

        match 'pattern', a Unix-style wildcard (glob) pattern.

        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.

S(9u
        Install a wheel to the specified paths. 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.

        The return value is a :class:`InstalledDistribution` instance unless
        ``options.lib_only`` is True, in which case the return value is ``None``.

    Represents a dependency graph between distributions.

    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.

    Represents a dependency graph between distributions.

    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.

        This is a convenience method for downloading a file from an URL.
        Normally, this will be a file from the index, though currently
        no check is made for this (i.e. a file can be downloaded from
        anywhere).

        The method is just like the :func:`urlretrieve` function in the
        standard library, except that it allows digest computation to be
        done during download and checking that the downloaded data
        matched any expected value.

        :param url: The URL of the file to be downloaded (assumed to be
                    available via an HTTP GET request).
        :param destfile: The pathname where the downloaded file is to be
                         saved.
        :param digest: If specified, this must be a (hasher, value)
                       tuple, where hasher is the algorithm used (e.g.
                       ``'md5'``) and ``value`` is the expected value.
        :param reporthook: The same as for :func:`urlretrieve` in the

    Return the default base location for distlib caches. If the directory does
    not exist, it is created. Use the suffix provided for the base directory,
    and default to '.distlib' if it isn't provided.

    On Windows, if LOCALAPPDATA is defined in the environment, then it is
    assumed to be a directory, and will be the parent directory of the result.
    On POSIX, and on Windows if LOCALAPPDATA is not defined, the user's home
    directory - using os.expanduser('~') - will be the parent directory of
    the result.

    The result is just the directory '.distlib' in the parent directory as
    determined above, or with the name specified with ``suffix``.

        Patterns are not quite the same as implemented by the 'fnmatch'

        DOS/Windows; and colon on Mac OS.

        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

pyparsing module - Classes and methods to define and execute parsing grammars

The pyparsing module is an alternative approach to creating and executing simple grammars,
vs. the traditional lex/yacc approach, or the use of regular expressions.  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 
C{", !"}), built up using L{Word}, L{Literal}, and L{And} elements 
(L{'+'} operator gives L{And} expressions, strings are auto-converted to
L{Literal} expressions)::

    from 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 L{ParseResults} object returned from L{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

        Define action to perform when successfully matching parse element definition.
        Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)},
        C{fn(loc,toks)}, C{fn(toks)}, or just C{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 C{L{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.

        Optional keyword arguments:
         - callDuringTry = (default=C{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 L{I{parseString}} for more information
        on parsing strings containing C{}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

        Extension to C{L{scanString}}, to modify matching text with modified tokens that may
        be returned from a parse action.  To use C{transformString}, define a grammar and
        attach a parse action to it that modifies the returned token list.
        Invoking C{transformString()} on a target string will then scan for matches,
        and replace the matched text patterns according to the logic in the parse
        action.  C{transformString()} returns the resulting transformed string.
        
        Example::
            wd = Word(alphas)

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using L{setDebugActions}. Prior to attempting
        to match the C{wd} expression, the debugging message C{"Match  at loc (,)"}
        is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
        message is shown. Also note the use of L{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 C{Word} expression without calling C{setName} is C{"W:(ABCD...)"}.

        Execute the parse expression on a series of test strings, showing each
        test, the parsed results or where the parse failed. 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=C{True}) - flag to pass to C{L{parseString}} when running tests           
         - comment - (default=C{'#'}) - expression for indicating embedded comments in the test 
              string; pass None to disable comment filtering
         - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline;
              if False, only dump nested list
         - printResults - (default=C{True}) prints test output to stdout
         - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing

        Returns: a (success, results) tuple, where success indicates that all tests succeeded
        (or failed if C{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

            Success

        Each test string must be on a single line. If you want to test a string that spans multiple
        lines, create a test like this::

            expr.runTest(r"this is a test\n of strings that spans \n 3 lines")
        
        (Note that this is a raw string literal, you must include the leading 'r'.)

    Token to exactly match a specified string as a keyword, that is, it must be
    immediately followed by a non-keyword character.  Compare with C{L{Literal}}:
     - C{Literal("if")} will match the leading C{'if'} in C{'ifAndOnlyIf'}.
     - C{Keyword("if")} will not; it will only match the leading C{'if'} in C{'if x=1'}, or C{'if(y==2)'}

     - C{identChars} is a string of characters that would be valid identifier characters,

    A variation on L{Literal} which matches "close" matches, that is, 
    strings with at most 'n' mismatching characters. C{CloseMatch} takes parameters:
     - C{match_string} - string to be matched
     - C{maxMismatches} - (C{default=1}) maximum number of mismatches allowed to count as a match
    
    The results from a successful parse will contain the matched text from the input string and the following named results:
     - C{mismatches} - a list of the positions within the match_string where mismatches were found
     - C{original} - the original match_string used to compare against the input string
    
    If C{mismatches} is an empty list, then the match was an exact match.
    
    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']})

    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 C{min} is 1 (a
    minimum value < 1 is not valid); the default values for C{max} and C{exact}
    are 0, meaning no maximum or exact length restriction. An optional
    C{excludeChars} parameter can list characters that might be found in 
    the input C{bodyChars} string; useful to define a word of all printables
    except for one or two characters, for instance.
    
    L{srange} is useful for defining custom character set strings for defining 
    C{Word} expressions, using range notation from regular expression character sets.
    
    A common mistake is to use C{Word} to match a specific literal string, as in 
    C{Word("Address")}. Remember that C{Word} uses the string argument to define
    I{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 L{Literal} or L{Keyword}.

    pyparsing includes helper strings for building Words:
     - L{alphas}
     - L{nums}
     - L{alphanums}
     - L{hexnums}
     - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
     - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - L{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=",")

    Token for matching strings that are delimited by quoting characters.
    
    Defined with the following parameters:
        - quoteChar - string of one or more characters defining the quote delimiting string
        - escChar - character to escape quotes, typically backslash (default=C{None})
        - escQuote - special quote sequence to escape an embedded quote string (such as SQL's "" to escape an embedded ") (default=C{None})
        - multiline - boolean indicating whether quotes can span multiple lines (default=C{False})
        - unquoteResults - boolean indicating whether the matched text should be unquoted (default=C{True})
        - endQuoteChar - string of one or more characters defining the end of the quote delimited string (default=C{None} => same as quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace (C{'\t'}, C{'\n'}, etc.) to actual whitespace (default=C{True})

    Example::
        qs = QuotedString('"')
        print(qs.searchString('lsjdf "This is the quote" sldjf'))
        complex_qs = QuotedString('{{', endQuoteChar='}}')

    Helper to quickly define a set of alternative Literals, and makes sure to do
    longest-first testing when there is a conflict, regardless of the input order,
    but returns a C{L{MatchFirst}} for best performance.

    Parameters:
     - strs - a string of space-delimited literals, or a collection of string literals
     - caseless - (default=C{False}) - treat all literals as caseless
     - useRegex - (default=C{True}) - as an optimization, will generate a Regex
          object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or

    Helper to easily and clearly define a dictionary by specifying the respective patterns
    for the key and value.  Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{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 C{Dict} results can include named token
    fields.

    Example::

        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))

    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 C{asString} argument is passed as C{False}, then the return value is a 
    C{L{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 C{L{originalTextFor}} contains expressions with defined
    results names, you must set C{asString} to C{False} if you want to preserve those
    results name values.

    Example::
        src = "this is test  bold text  normal text "
        for tag in ("b","i"):

    Helper to construct opening and closing tag expressions for HTML, given a tag name. Matches
    tags in either upper or lower case, attributes with namespaces and with quoted or unquoted values.

    Example::
        text = 'More info at the pyparsing wiki page'
        # makeHTMLTags returns pyparsing expressions for the opening and closing tags as a 2-tuple
        a,a_end = makeHTMLTags("A")
        link_expr = a + SkipTo(a_end)("link_text") + a_end

    Helper to create a validating parse action to be used with start tags created
    with C{L{makeXMLTags}} or C{L{makeHTMLTags}}. Use C{withAttribute} to qualify a starting tag
    with a required attribute value, to avoid false matches on common tags such as
    C{} or C{
}.

    Call C{withAttribute} with a series of attribute names and values. Specify the list
    of filter attributes names and values as:
     - keyword arguments, as in C{(align="right")}, or
     - as an explicit dict with C{**} operator, when an attribute name is also a Python
          reserved word, as in C{**{"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 C{class} (with or without a namespace), use C{L{withClass}}.

    To verify that the attribute exists, but without specifying a value, pass
    C{withAttribute.ANY_VALUE} as the value.

    Example::
        html = '''

    Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  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 L{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 C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
       - parseAction is the parse action to be associated with
          expressions matching this operator expression (the
          parse action tuple member may be omitted)
     - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
     - rpar - expression for matching right-parentheses (default=C{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]]]

    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=C{"("}); can also be a pyparsing expression
     - closer - closing character for a nested list (default=C{")"}); can also be a pyparsing expression
     - content - expression for items within the nested lists (default=C{None})
     - ignoreExpr - expression for ignoring opening and closing delimiters (default=C{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 C{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 C{L{Or}} or C{L{MatchFirst}}.
    The default is L{quotedString}, but if no expressions are to be ignored,
    then pass C{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, "()")

                      + LPAR + Optional(delimitedList(arg), [])("args") + RPAR 
                      + code_body("body"))

    Helper method for defining space-delimited indentation blocks, such as
    those used to define block statements in Python source code.

    Parameters:
     - blockStatementExpr - expression defining syntax of statement that
            is repeated within the indented block
     - indentStack - list created by caller to manage indentation stack
            (multiple statementWithIndentedBlock expressions within a single grammar
            should share a common indentStack)
     - indent - boolean indicating whether block must be indented beyond the
            the current level; set to False for block of left-most statements
            (default=C{True})

    A valid block must contain at least one C{blockStatement}.

    Typical user cache directories are:

    On Windows the only suggestion in the MSDN docs is that local settings go in
    the `CSIDL_LOCAL_APPDATA` directory. This is identical to the non-roaming
    app data dir (the default returned by `user_data_dir` above). Apps typically
    put cache data somewhere *under* the given dir here. Some examples:
        ...\Mozilla\Firefox\Profiles\\Cache
        ...\Acme\SuperApp\Cache\1.0
    OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.
    This can be disabled with the `opinion=False` option.

lockfile.py - Platform-independent advisory file locks.

Requires Python 2.5 unless you apply 2.4.diff
Locking is done on a per-thread basis instead of a per-process basis.

Usage:

>>> lock = LockFile('somefile')
>>> try:
...     lock.acquire()
... except AlreadyLocked:
...     print 'somefile', 'is locked already.'
... except LockFailed:
...     print 'somefile', 'can\'t be locked.'
... else:
...     print 'got lock'
got lock
>>> print lock.is_locked()
True
>>> lock.release()

>>> lock = LockFile('somefile')
>>> print lock.is_locked()
False
>>> with lock:
...    print lock.is_locked()
True
>>> print lock.is_locked()
False

>>> lock = LockFile('somefile')
>>> # It is okay to lock twice from the same thread...
>>> with lock:
...     lock.acquire()
...
>>> # Though no counter is kept, so you can't unlock multiple times...
>>> print lock.is_locked()
False

Exceptions:

    Error - base class for other exceptions
        LockError - base class for all locking exceptions
            AlreadyLocked - Another thread or process already holds the lock
            LockFailed - Lock failed for some other reason
        UnlockError - base class for all unlocking exceptions
            AlreadyUnlocked - File was not locked.
            NotMyLock - File was locked but not by the current thread/process

lockfile.py - Platform-independent advisory file locks.

Requires Python 2.5 unless you apply 2.4.diff
Locking is done on a per-thread basis instead of a per-process basis.

Usage:

>>> lock = LockFile('somefile')
>>> try:
...     lock.acquire()
... except AlreadyLocked:
...     print 'somefile', 'is locked already.'
... except LockFailed:
...     print 'somefile', 'can\'t be locked.'
... else:
...     print 'got lock'
got lock
>>> print lock.is_locked()
True
>>> lock.release()

>>> lock = LockFile('somefile')
>>> print lock.is_locked()
False
>>> with lock:
...    print lock.is_locked()
True
>>> print lock.is_locked()
False

>>> lock = LockFile('somefile')
>>> # It is okay to lock twice from the same thread...
>>> with lock:
...     lock.acquire()
...
>>> # Though no counter is kept, so you can't unlock multiple times...
>>> print lock.is_locked()
False

Exceptions:

    Error - base class for other exceptions
        LockError - base class for all locking exceptions
            AlreadyLocked - Another thread or process already holds the lock
            LockFailed - Lock failed for some other reason
        UnlockError - base class for all unlocking exceptions
            AlreadyUnlocked - File was not locked.
            NotMyLock - File was locked but not by the current thread/process

"""
lockfile.py - Platform-independent advisory file locks.

Requires Python 2.5 unless you apply 2.4.diff
Locking is done on a per-thread basis instead of a per-process basis.

Usage:

>>> lock = LockFile('somefile')
>>> try:
...     lock.acquire()
... except AlreadyLocked:
...     print 'somefile', 'is locked already.'
... except LockFailed:
...     print 'somefile', 'can\\'t be locked.'
... else:
...     print 'got lock'
got lock
>>> print lock.is_locked()
True
>>> lock.release()

>>> lock = LockFile('somefile')
>>> print lock.is_locked()
False
>>> with lock:
...    print lock.is_locked()
True
>>> print lock.is_locked()
False

>>> lock = LockFile('somefile')
>>> # It is okay to lock twice from the same thread...
>>> with lock:
...     lock.acquire()
...
>>> # Though no counter is kept, so you can't unlock multiple times...
>>> print lock.is_locked()
False

Exceptions:

    Error - base class for other exceptions
        LockError - base class for all locking exceptions
            AlreadyLocked - Another thread or process already holds the lock
            LockFailed - Lock failed for some other reason
        UnlockError - base class for all unlocking exceptions
            AlreadyUnlocked - File was not locked.
            NotMyLock - File was locked but not by the current thread/process

Package resource API
--------------------

A resource is a logical file contained within a package, or a logical
subdirectory thereof.  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.

    distutils.util.get_platform() normally reports the minimum version

    distutils.  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.

            The following error occurred while trying to extract file(s) to the Python egg
            cache:

              {old_exc}

            The Python egg cache directory is currently set to:

              {cache_path}

            Perhaps your account does not have write access to this directory?  You can
            change the cache directory by setting the PYTHON_EGG_CACHE environment
            variable to point to an accessible directory.

        If the default extraction path is overridden and set to an insecure
        location, such as /tmp, it opens up an opportunity for an attacker to
        replace an extracted file with an unauthorized payload. Warn the user

        This is where Mac header rewrites should be done; other platforms don't
        have anything special they should do.

        Resource providers should call this method ONLY after successfully
        extracting a compressed resource.  They must NOT call it on resources
        that are already in the filesystem.

        `tempname` is the current (temporary) name of the file, and `filename`
        is the name it will be renamed to by the caller after this routine
        returns.

        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.

        (Note: you may not change the extraction path for a given resource
        manager once resources have been extracted, unless you first call
        ``cleanup_resources()``.)

        This function does not have any concurrency protection, so it should
        generally only be called when the extraction path is a temporary
        directory exclusive to a single process.  This method is not

Package resource API
--------------------

A resource is a logical file contained within a package, or a logical
subdirectory thereof.  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.

    distutils.util.get_platform() normally reports the minimum version
    of Mac OS X that would be required to *use* extensions produced by
    distutils.  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.

Package resource API
--------------------

A resource is a logical file contained within a package, or a logical
subdirectory thereof.  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.

The ``distro`` package (``distro`` stands for Linux Distribution) provides
information about the Linux distribution it runs on, such as a reliable
machine-readable distro ID, or version information.

It is a renewed alternative implementation for Python's original
:py:func:`platform.linux_distribution` function, but it provides much more
functionality. An alternative implementation became necessary because Python
3.5 deprecated this function, and Python 3.7 is expected to remove it
altogether. Its predecessor function :py:func:`platform.dist` was already
deprecated since Python 2.6 and is also expected to be removed in Python 3.7.
Still, there are many cases in which access to Linux distribution information
is needed. See `Python issue 1322 `_ for
more information.

    If you have a need to get distros for reliable IDs added into this set,
    or if you find that the :func:`distro.id` function returns a different
    distro ID for one of the listed distros, please create an issue in the
    `distro issue tracker`_.

    **Lookup hierarchy and transformations:**

    First, the ID is obtained from the following sources, in the specified
    order. The first available and non-empty value is used:

    * the value of the "ID" attribute of the os-release file,

    * the value of the "Distributor ID" attribute returned by the lsb_release
      command,

    * the first part of the file name of the distro release file,

    The so determined ID value then passes the following transformations,
    before it is returned by this method:

    * it is translated to lower case,

    * blanks (which should not be there anyway) are translated to underscores,

    * a normalization of the ID is performed, based upon
      `normalization tables`_. The purpose of this normalization is to ensure
      that the ID is as reliable as possible, even across incompatible changes
      in the Linux distributions. A common reason for an incompatible change is
      the addition of an os-release file, or the addition of the lsb_release
      command, with ID values that differ from what was previously determined
      from the distro release file name.

              are also functionally equivalent. That is to say, failing to
              provide a subnetmask will create an object with a mask of /32.

              If the mask (portion after the / in the argument) is given in
              dotted quad form, it is treated as a netmask if it starts with a
              non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it
              starts with a zero field (e.g. 0.255.255.255 == /8), with the
              single exception of an all-zero mask which is treated as a
              netmask == /0. If no mask is given, a default of /32 is used.

              Additionally, an integer can be passed, so
              IPv4Network('192.0.2.1') == IPv4Network(3221225985)

              are all functionally the same in IPv6.  That is to say,
              failing to provide a subnetmask will create an object with
              a mask of /128.

              Additionally, an integer can be passed, so
              IPv6Network('2001:db8::') ==

            strict: A boolean. If true, ensure that we have been passed
              A true network address, eg, 2001:db8::1000/124 and not an
              IP address on a network, eg, 2001:db8::1/124.

ZdZdZdZdZededddZRS(sThe built-in HTTP Adapter for urllib3.

    Provides a general-case interface for Requests sessions to contact HTTP and
    HTTPS urls by implementing the Transport Adapter interface. This class will
    usually be created by the :class:`Session ` class under the
    covers.

    :param pool_connections: The number of urllib3 connection pools to cache.
    :param pool_maxsize: The maximum number of connections to save in the pool.
    :param max_retries: The maximum number of retries each connection
        should attempt. Note, this applies only to failed DNS lookups, socket
        connections and connection timeouts, never to requests where data has
        made it to the server. By default, Requests does not retry failed
        connections. If you need granular control over the conditions under
        which we retry a request, import urllib3's ``Retry`` class and pass
        that instead.
    :param pool_block: Whether the connection pool should block for connections.

    Usage::

      >>> import requests
      >>> s = requests.Session()
      >>> a = requests.adapters.HTTPAdapter(max_retries=3)
      >>> s.mount('http://', a)

ZedZRS(sWraps a `requests.Request` to mimic a `urllib2.Request`.

    The code in `cookielib.CookieJar` expects this interface in order to correctly
    manage cookie policies, i.e., determine whether a cookie can be set, given the
    domains of the request and the cookie.

    The original request object is read-only. The client is responsible for collecting
    the new headers via `get_new_headers()` and interpreting them appropriately. You
    probably want `get_cookie_header`, defined below.

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~

Requests is an HTTP library, written in Python, for human beings. Basic GET
usage:

   >>> import requests
   >>> r = requests.get('https://www.python.org')
   >>> r.status_code
   200
   >>> 'Python is a programming language' in r.content
   True

... or POST:

   >>> payload = dict(key1='value1', key2='value2')
   >>> r = requests.post('http://httpbin.org/post', data=payload)
   >>> print(r.text)
   {
     ...
     "form": {
       "key2": "value2",
       "key1": "value1"
     },
     ...
   }

The other HTTP methods are supported - see `requests.api`. Full documentation
is at .

    In particular, parse comma-separated lists where the elements of
    the list may include quoted-strings.  A quoted-string could
    contain a comma.  A non-quoted string could have quotes in the
    middle.  Quotes are removed automatically after parsing.

    It basically works like :func:`parse_set_header` just that items
    may appear multiple times and case sensitivity is preserved.

    The return value is a standard :class:`list`:

    >>> parse_list_header('token, "quoted value"')
    ['token', 'quoted value']

    To create a header from the :class:`list` again, use the
    :func:`dump_header` function.

    If there is no value for a key it will be `None`:

    {'key_without_value': None}

Compatibility code to be able to use `cookielib.CookieJar` with requests.

ZedZRS(sWraps a `requests.Request` to mimic a `urllib2.Request`.

    The code in `cookielib.CookieJar` expects this interface in order to correctly
    manage cookie policies, i.e., determine whether a cookie can be set, given the
    domains of the request and the cookie.

    The original request object is read-only. The client is responsible for collecting
    the new headers via `get_new_headers()` and interpreting them appropriately. You
    probably want `get_cookie_header`, defined below.

RS(sA case-insensitive ``dict``-like object.

    Implements all methods and operations of
    ``collections.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.

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~

Requests is an HTTP library, written in Python, for human beings. Basic GET
usage:

   >>> import requests
   >>> r = requests.get('https://www.python.org')
   >>> r.status_code
   200
   >>> 'Python is a programming language' in r.content
   True

... or POST:

   >>> payload = dict(key1='value1', key2='value2')
   >>> r = requests.post('http://httpbin.org/post', data=payload)
   >>> print(r.text)
   {
     ...
     "form": {
       "key2": "value2",
       "key1": "value1"
     },
     ...
   }

The other HTTP methods are supported - see `requests.api`. Full documentation
is at .

    In particular, parse comma-separated lists where the elements of
    the list may include quoted-strings.  A quoted-string could
    contain a comma.  A non-quoted string could have quotes in the
    middle.  Quotes are removed automatically after parsing.

    It basically works like :func:`parse_set_header` just that items
    may appear multiple times and case sensitivity is preserved.

    The return value is a standard :class:`list`:

    >>> parse_list_header('token, "quoted value"')
    ['token', 'quoted value']

    To create a header from the :class:`list` again, use the
    :func:`dump_header` function.

    If there is no value for a key it will be `None`:

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~

Requests is an HTTP library, written in Python, for human beings. Basic GET
usage:

   >>> import requests
   >>> r = requests.get('https://www.python.org')
   >>> r.status_code
   200
   >>> 'Python is a programming language' in r.content
   True

... or POST:

   >>> payload = dict(key1='value1', key2='value2')
   >>> r = requests.post('http://httpbin.org/post', data=payload)
   >>> print(r.text)
   {
     ...
     "form": {
       "key2": "value2",
       "key1": "value1"
     },
     ...
   }

The other HTTP methods are supported - see `requests.api`. Full documentation
is at .

ZdZdZdZdZededddZRS(sThe built-in HTTP Adapter for urllib3.

    Provides a general-case interface for Requests sessions to contact HTTP and
    HTTPS urls by implementing the Transport Adapter interface. This class will
    usually be created by the :class:`Session ` class under the
    covers.

    :param pool_connections: The number of urllib3 connection pools to cache.
    :param pool_maxsize: The maximum number of connections to save in the pool.
    :param max_retries: The maximum number of retries each connection
        should attempt. Note, this applies only to failed DNS lookups, socket
        connections and connection timeouts, never to requests where data has
        made it to the server. By default, Requests does not retry failed
        connections. If you need granular control over the conditions under
        which we retry a request, import urllib3's ``Retry`` class and pass
        that instead.
    :param pool_block: Whether the connection pool should block for connections.

    Usage::

      >>> import requests
      >>> s = requests.Session()
      >>> a = requests.adapters.HTTPAdapter(max_retries=3)
      >>> s.mount('http://', a)

              single exception of an all-zero mask which is treated as a
              netmask == /0. If no mask is given, a default of /32 is used.

    The ``UniversalDetector`` class underlies the ``chardet.detect`` function
    and coordinates all of the different charset probers.

    To get a ``dict`` containing an encoding and its confidence, you can simply
    run:

    .. code::

            u = UniversalDetector()
            u.feed(some_bytes)
            u.close()
            detected = u.result

        Reset the UniversalDetector and all of its probers back to their
        initial states.  This is called by ``__init__``, so you only need to
        call this directly in between analyses of different documents.

        Takes a chunk of a document and feeds it through all of the relevant
        charset probers.

        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``.

    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.

        We define three types of bytes:
        alphabet: english alphabets [a-zA-Z]
        international: international characters [-]
        marker: everything else [^a-zA-Z-]

        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.

        This filter applies to all scripts which do not use English characters.

        Returns a copy of ``buf`` that retains only the sequences of English
        alphabet and high byte characters that are not between <> characters.
        Also retains English alphabet and high byte characters immediately
        before occurrences of >.

        This filter can be applied to all scripts which contain both English
        characters and extended ASCII characters, but is currently only used by
        ``Latin1Prober``.

    The ``UniversalDetector`` class underlies the ``chardet.detect`` function
    and coordinates all of the different charset probers.

    To get a ``dict`` containing an encoding and its confidence, you can simply
    run:

    .. code::

            u = UniversalDetector()
            u.feed(some_bytes)
            u.close()
            detected = u.result

        Takes a chunk of a document and feeds it through all of the relevant
        charset probers.

        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``.

    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.

        international: international characters [-]
        marker: everything else [^a-zA-Z-]

        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.

        This filter applies to all scripts which do not use English characters.

from .charsetprober import CharSetProber
from .enums import ProbingState

# This prober doesn't actually recognize a language or a charset.
# It is a helper prober for the use of the Hebrew model probers

### General ideas of the Hebrew charset recognition ###
#
# Four main charsets exist in Hebrew:
# "ISO-8859-8" - Visual Hebrew
# "windows-1255" - Logical Hebrew
# "ISO-8859-8-I" - Logical Hebrew
# "x-mac-hebrew" - ?? 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. The answer is returned in the form of the name of the
# charset identified, either "windows-1255" or "ISO-8859-8".

    Backwards-compatible to httplib's HTTPResponse but the response ``body`` is

    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 httplib.HTTPResponse:

    :param preload_content:
        If True, the response's body will be preloaded during construction.

    :param decode_content:
        If True, attempts to decode specific content-encoding's based on headers
        (like 'gzip' and 'deflate') will be skipped and raw data will be used
        instead.

    :param original_response:
        When this HTTPResponse wrapper is generated from an httplib.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.

        Host used for this HTTP Connection (e.g. "localhost"), passed into

        Port used for this HTTP Connection (None is equivalent to 80), passed

        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.

        .. 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 body:
            Data to send in the request body (useful for creating
            POST requests, see HTTPConnectionPool.post_url for
            more convenience).

        :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.

    Based on httplib.HTTPConnection but provides an extra constructor
    backwards-compatibility layer between older and newer Pythons.

    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.

        .. note:: This is ignored for Python 2.6. It is only applied for 2.7 and 3.x

      - ``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::

            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., ``[]``).

    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. It's a good idea to set this to some sensibly-high value to
        account for unexpected edge cases and avoid infinite retry loops.

        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 iterable method_whitelist:
        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_METHOD_WHITELIST`.

        Set to a ``False`` value to retry on any verb.

    :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 ``method_whitelist``
        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 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

    :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.

class Retry(object):
    """ Retry configuration.

    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. It's a good idea to set this to some sensibly-high value to
        account for unexpected edge cases and avoid infinite retry loops.

        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 iterable method_whitelist:
        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_METHOD_WHITELIST`.

        Set to a ``False`` value to retry on any verb.

    :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 ``method_whitelist``
        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 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

    :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.

    Timeouts can be defined as a default for a pool::

        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)::

        response = http.request('GET', 'http://example.com/', timeout=Timeout(10))

    Timeouts can be disabled by setting all the parameters to ``None``::

        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: integer, float, or None

    :param connect:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout for connection attempts.

    :type connect: integer, float, or None

    :param read:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout.

    :type read: integer, 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. It's a good idea to set this to some sensibly-high value to
        account for unexpected edge cases and avoid infinite retry loops.

        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 iterable method_whitelist:
        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_METHOD_WHITELIST`.

        Set to a ``False`` value to retry on any verb.

    :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 ``method_whitelist``
        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 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

    :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.

        Convert self into a url

        This function should more or less round-trip with :func:`.parse_url`. The
        returned url may not be exactly the same as the url inputted to
        :func:`.parse_url`, but it should be equivalent by the RFC (e.g., urls
        with a blank port will have : removed).

        Example: ::

            >>> U = parse_url('http://google.com/mail/')
            >>> U.url
            'http://google.com/mail/'
            >>> Url('http', 'username:password', 'host.com', 80,
            ... '/path', 'query', 'fragment').url

    Timeouts can be defined as a default for a pool::

        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)::

        response = http.request('GET', 'http://example.com/', timeout=Timeout(10))

    Timeouts can be disabled by setting all the parameters to ``None``::

        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: integer, float, or None

    :param connect:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout for connection attempts.

    :type connect: integer, float, or None

    :param read:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout.

    :type read: integer, 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.

    By default, this function does a lot of the same work that
    ``ssl.create_default_context`` does on Python 3.4+. It:

    - Disables SSLv2, SSLv3, and compression
    - Sets a restricted set of server ciphers

    If you wish to enable SSLv3, you can do::

        from urllib3.util import ssl_
        context = ssl_.create_urllib3_context()
        context.options &= ~ssl_.OP_NO_SSLv3

    You can do the same to enable compression (substituting ``COMPRESSION``
    for ``SSLv3`` in the last line above).

    :param ssl_version:
        The desired protocol version to use. This will default to
        PROTOCOL_SSLv23 which will negotiate the highest protocol that both
        the server and your installation of OpenSSL support.
    :param cert_reqs:
        Whether to require the certificate verification. This defaults to
        ``ssl.CERT_REQUIRED``.
    :param options:
        Specific OpenSSL options. These default to ``ssl.OP_NO_SSLv2``,
        ``ssl.OP_NO_SSLv3``, ``ssl.OP_NO_COMPRESSION``.

    All arguments except for server_hostname, ssl_context, and ca_cert_dir have
    the same meaning as they do when using :func:`ssl.wrap_socket`.

    :param server_hostname:
        When SNI is supported, the expected hostname of the certificate
    :param ssl_context:
        A pre-made :class:`SSLContext` object. If none is provided, one will
        be created using :func:`create_urllib3_context`.
    :param ciphers:
        A string of ciphers we wish the client to support. This is not
        supported on Python 2.6 as the ssl module does not support it.
    :param ca_cert_dir:
        A directory containing CA certificates in multiple separate files, as
        supported by OpenSSL's -CApath flag or the capath argument to
        SSLContext.load_verify_locations().
    R'tload_default_certsR9sAn HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

    A selector supports registering file objects to be monitored
    for specific I/O events.

    A file object is a file descriptor or any object with a
    `fileno()` method. An arbitrary object can be attached to the
    file object which can be used for example to store context info,
    a callback, etc.

    A selector can use various implementations (select(), poll(), epoll(),
    and kqueue()) depending on the platform. The 'DefaultSelector' class uses
    the most efficient implementation for the current platform.

    By default, this function does a lot of the same work that
    ``ssl.create_default_context`` does on Python 3.4+. It:

    - Disables SSLv2, SSLv3, and compression
    - Sets a restricted set of server ciphers

    If you wish to enable SSLv3, you can do::

        from urllib3.util import ssl_
        context = ssl_.create_urllib3_context()
        context.options &= ~ssl_.OP_NO_SSLv3

    You can do the same to enable compression (substituting ``COMPRESSION``
    for ``SSLv3`` in the last line above).

    :param ssl_version:
        The desired protocol version to use. This will default to
        PROTOCOL_SSLv23 which will negotiate the highest protocol that both
        the server and your installation of OpenSSL support.
    :param cert_reqs:
        Whether to require the certificate verification. This defaults to
        ``ssl.CERT_REQUIRED``.
    :param options:
        Specific OpenSSL options. These default to ``ssl.OP_NO_SSLv2``,
        ``ssl.OP_NO_SSLv3``, ``ssl.OP_NO_COMPRESSION``.
    :param ciphers:
        Which cipher suites to allow the server to select.

    All arguments except for server_hostname, ssl_context, and ca_cert_dir have

        A pre-made :class:`SSLContext` object. If none is provided, one will

    :param ciphers:
        A string of ciphers we wish the client to support. This is not
        supported on Python 2.6 as the ssl module does not support it.
    :param ca_cert_dir:
        A directory containing CA certificates in multiple separate files, as

    A selector supports registering file objects to be monitored
    for specific I/O events.

    A file object is a file descriptor or any object with a
    `fileno()` method. An arbitrary object can be attached to the
    file object which can be used for example to store context info,
    a callback, etc.

    A selector can use various implementations (select(), poll(), epoll(),
    and kqueue()) depending on the platform. The 'DefaultSelector' class uses
    the most efficient implementation for the current platform.

    Timeouts can be defined as a default for a pool::

        response = http.request('GET', 'http://example.com/')

    Or per-request (which overrides the default for the pool)::

        response = http.request('GET', 'http://example.com/', timeout=Timeout(10))

    Timeouts can be disabled by setting all the parameters to ``None``::

        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: integer, float, or None

    :param connect:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout for connection attempts.

    :type connect: integer, float, or None

    :param read:
        The maximum amount of time 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
        `_.
        None will set an infinite timeout.

    :type read: integer, 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.

        Convert self into a url

        This function should more or less round-trip with :func:`.parse_url`. The
        returned url may not be exactly the same as the url inputted to
        :func:`.parse_url`, but it should be equivalent by the RFC (e.g., urls
        with a blank port will have : removed).

        Example: ::

            >>> U = parse_url('http://google.com/mail/')
            >>> U.url
            'http://google.com/mail/'
            >>> Url('http', 'username:password', 'host.com', 80,
            ... '/path', 'query', 'fragment').url
            'http://username:password@host.com:80/path?query#fragment'

    Given a string and an iterable of delimiters, split on the first found
    delimiter. Return two split parts and the matched delimiter.

    If not found, then the first part is the full input string.

    Example::

        >>> split_first('foo/bar?baz', '?/=')
        ('foo', 'bar?baz', '/')
        >>> split_first('foo/bar?baz', '123')
        ('foo/bar?baz', '', None)

    Scales linearly with number of delims. Not ideal for large number of delims.

    HTTP Response container.

    Backwards-compatible to httplib's 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 httplib.HTTPResponse:

    :param preload_content:
        If True, the response's body will be preloaded during construction.

    :param decode_content:
        If True, attempts to decode specific content-encoding's based on headers
        (like 'gzip' and 'deflate') will be skipped and raw data will be used
        instead.

    :param original_response:
        When this HTTPResponse wrapper is generated from an httplib.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. Otherwise, raise error.

            returned despite of the state of the underlying file object. This
            is useful if you want the ``.data`` property to continue working

This module contains provisional support for SOCKS proxies from within
urllib3. This module supports SOCKS4 (specifically the SOCKS4A variant) 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:

- SOCKS4
- SOCKS4a
- SOCKS5
- Usernames and passwords for the SOCKS proxy

Known Limitations:

- Currently PySocks does not support contacting remote websites via literal
  IPv6 addresses. Any such connection attempt will fail. You must use a domain
  name.
- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any
  such connection attempt will fail.
i(tabsolute_importNi(tDependencyWarningsSOCKS support in urllib3 requires the installation of optional dependencies: specifically, PySocks.

This module provides a pool manager that uses Google App Engine's
`URLFetch Service `_.

Example usage::

    from urllib3 import PoolManager
    from 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 `_ 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
   `_ 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
`_, you can use the standard
:class:`PoolManager` without any configuration or special environment variables.

    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
    `_.

    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 megabtyes.
        * If you use an unsupported request method such as OPTIONS.

    Beyond those cases, it will raise normal urllib3 errors.

This module provides a pool manager that uses Google App Engine's
`URLFetch Service `_.

Example usage::

    from urllib3 import PoolManager
    from 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 `_ 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
   `_ 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
`_, you can use the standard
:class:`PoolManager` without any configuration or special environment variables.

SSL with SNI_-support for Python 2. Follow these instructions if you would
like to verify SSL 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:

    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::

    try:
        import urllib3.contrib.pyopenssl
        urllib3.contrib.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`_).

If you want to configure the default list of supported cipher suites, you can
set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

"""
This module contains provisional support for SOCKS proxies from within
urllib3. This module supports SOCKS4 (specifically the SOCKS4A variant) 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:

- SOCKS4
- SOCKS4a
- SOCKS5
- Usernames and passwords for the SOCKS proxy

Known Limitations:

- Currently PySocks does not support contacting remote websites via literal
  IPv6 addresses. Any such connection attempt will fail. You must use a domain
  name.
- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any
  such connection attempt will fail.

This module provides a pool manager that uses Google App Engine's
`URLFetch Service `_.

Example usage::

    from urllib3 import PoolManager
    from 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 `_ 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
   `_ 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
`_, you can use the standard
:class:`PoolManager` without any configuration or special environment variables.

    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
    `_.

    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 megabtyes.
        * If you use an unsupported request method such as OPTIONS.

    Beyond those cases, it will raise normal urllib3 errors.

This module uses ctypes to bind a whole bunch of functions and constants from
SecureTransport. 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.

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:

This module uses ctypes to bind a whole bunch of functions and constants from
SecureTransport. 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.

SecureTranport support for urllib3 via ctypes.

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 urllib3.contrib.securetransport
    urllib3.contrib.securetransport.inject_into_urllib3()

Happy TLSing!

#    2. The callbacks don't mutate the dictionary, they only read from it, and
#       so cannot conflict with any of the insertions.

This module contains provisional support for SOCKS proxies from within
urllib3. This module supports SOCKS4 (specifically the SOCKS4A variant) 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:

- SOCKS4
- SOCKS4a
- SOCKS5
- Usernames and passwords for the SOCKS proxy

Known Limitations:

- Currently PySocks does not support contacting remote websites via literal
  IPv6 addresses. Any such connection attempt will fail. You must use a domain
  name.
- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any
  such connection attempt will fail.
i(tabsolute_importNi(tDependencyWarningsSOCKS support in urllib3 requires the installation of optional dependencies: specifically, PySocks.

FPKZ*q;;6site-packages/pip/_vendor/urllib3/contrib/pyopenssl.pynu["""
SSL with SNI_-support for Python 2. Follow these instructions if you would
like to verify SSL 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:

    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::

    try:
        import urllib3.contrib.pyopenssl
        urllib3.contrib.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`_).

If you want to configure the default list of supported cipher suites, you can
set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

    Thread-safe connection pool for one host.

    :param host:
        Host used for this HTTP Connection (e.g. "localhost"), passed into
        :class:`httplib.HTTPConnection`.

    :param port:
        Port used for this HTTP Connection (None is equivalent to 80), passed
        into :class:`httplib.HTTPConnection`.

    :param strict:
        Causes BadStatusLine to be raised if the status line can't be parsed
        as a valid HTTP/1.0 or 1.1 status line, passed into
        :class:`httplib.HTTPConnection`.

        .. note::
           Only works in Python 2. 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.connectionpool.ProxyManager`"

    :param _proxy_headers:
        A dictionary with proxy headers, should not be used directly,
        instead, see :class:`urllib3.connectionpool.ProxyManager`"

    :param \**conn_kw:
        Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`,
        :class:`urllib3.connection.HTTPSConnection` instances.

S|S("s
        Get a connection from the pool and perform an HTTP request. 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 body:
            Data to send in the request body (useful for creating
            POST requests, see HTTPConnectionPool.post_url for
            more convenience).

        :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

    Same as :class:`.HTTPConnectionPool`, but HTTPS.

    When Python is compiled with the :mod:`ssl` module, then
    :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates,
    instead of :class:`.HTTPSConnection`.

    :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``,
    ``assert_hostname`` and ``host`` in this order to verify connections.
    If ``assert_hostname`` is False, no verification is done.

    The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs``,
    ``ca_cert_dir``, and ``ssl_version`` are only used if :mod:`ssl` is
    available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade
    the connection socket into an SSL socket.

    Given a url, return an :class:`.ConnectionPool` instance of its host.

    This is a shortcut for not having to parse out the scheme, host, and port
    of the url before creating an :class:`.ConnectionPool` instance.

        Absolute URL string that must include the scheme. Port is optional.

    :param \**kw:
        Passes additional parameters to the constructor of the appropriate
        :class:`.ConnectionPool`. Useful for specifying things like
        timeout, maxsize, headers, etc.

    Thread-safe connection pool for one host.

    :param host:
        Host used for this HTTP Connection (e.g. "localhost"), passed into
        :class:`httplib.HTTPConnection`.

    :param port:
        Port used for this HTTP Connection (None is equivalent to 80), passed
        into :class:`httplib.HTTPConnection`.

    :param strict:
        Causes BadStatusLine to be raised if the status line can't be parsed
        as a valid HTTP/1.0 or 1.1 status line, passed into
        :class:`httplib.HTTPConnection`.

        .. note::
           Only works in Python 2. 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.connectionpool.ProxyManager`"

    :param _proxy_headers:
        A dictionary with proxy headers, should not be used directly,
        instead, see :class:`urllib3.connectionpool.ProxyManager`"

    :param \**conn_kw:
        Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`,
        :class:`urllib3.connection.HTTPSConnection` instances.

S|S("s
        Get a connection from the pool and perform an HTTP request. 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 body:
            Data to send in the request body (useful for creating
            POST requests, see HTTPConnectionPool.post_url for
            more convenience).

        :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

    Same as :class:`.HTTPConnectionPool`, but HTTPS.

    When Python is compiled with the :mod:`ssl` module, then
    :class:`.VerifiedHTTPSConnection` is used, which *can* verify certificates,
    instead of :class:`.HTTPSConnection`.

    :class:`.VerifiedHTTPSConnection` uses one of ``assert_fingerprint``,
    ``assert_hostname`` and ``host`` in this order to verify connections.
    If ``assert_hostname`` is False, no verification is done.

    The ``key_file``, ``cert_file``, ``cert_reqs``, ``ca_certs``,
    ``ca_cert_dir``, and ``ssl_version`` are only used if :mod:`ssl` is
    available and are fed into :meth:`urllib3.util.ssl_wrap_socket` to upgrade
    the connection socket into an SSL socket.

    Convenience mixin for classes who implement a :meth:`urlopen` method, such
    as :class:`~urllib3.connectionpool.HTTPConnectionPool` and
    :class:`~urllib3.poolmanager.PoolManager`.

    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.

    Initializer parameters:

    :param headers:
        Headers to include with all requests, unless other headers are given
        explicitly.

        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`,

    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 httplib.HTTPResponse:

    :param preload_content:
        If True, the response's body will be preloaded during construction.

    :param decode_content:
        If True, attempts to decode specific content-encoding's based on headers
        (like 'gzip' and 'deflate') will be skipped and raw data will be used
        instead.

    :param original_response:
        When this HTTPResponse wrapper is generated from an httplib.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. Otherwise, raise error.

        '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 mimick 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.

    A ``dict`` like container for storing HTTP Headers.

    Field names are stored and compared case-insensitively in compliance with

    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

    Convenience mixin for classes who implement a :meth:`urlopen` method, such
    as :class:`~urllib3.connectionpool.HTTPConnectionPool` and
    :class:`~urllib3.poolmanager.PoolManager`.

    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.

    Initializer parameters:

    :param headers:
        Headers to include with all requests, unless other headers are given
        explicitly.

        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`,

            returned, or '/etc/xdg/', if XDG_CONFIG_DIRS is not set

    Typical user data directories are:
        macOS:      same as site_data_dir
        Unix:       /etc/xdg/ or $XDG_CONFIG_DIRS[i]/ for each value in
                    $XDG_CONFIG_DIRS
        Win *:      same as site_data_dir
        Vista:      (Fail! "C:\ProgramData" is a hidden *system* directory on Vista.)

    For Unix, this is using the $XDG_CONFIG_DIRS[0] default, if multipath=False

    WARNING: Do not use this on Windows. See the Vista-Fail note above for why.

            pass False to disable it.
        "version" is an optional version path element to append to the

            "Cache" to the base app data dir for Windows. See
            discussion below.

    Typical user cache directories are:
        macOS:      ~/Library/Caches/
        Unix:       ~/.cache/ (XDG default)
        Win XP:     C:\Documents and Settings\\Local Settings\Application Data\\\Cache
        Vista:      C:\Users\\AppData\Local\\\Cache

    On Windows the only suggestion in the MSDN docs is that local settings go in
    the `CSIDL_LOCAL_APPDATA` directory. This is identical to the non-roaming
    app data dir (the default returned by `user_data_dir` above). Apps typically
    put cache data somewhere *under* the given dir here. Some examples:
        ...\Mozilla\Firefox\Profiles\\Cache
        ...\Acme\SuperApp\Cache\1.0
    OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.

    Typical user cache directories are:
        macOS:      ~/Library/Logs/
        Unix:       ~/.cache//log  # or under $XDG_CACHE_HOME if defined
        Win XP:     C:\Documents and Settings\\Local Settings\Application Data\\\Logs

    On Windows the only suggestion in the MSDN docs is that local settings
    go in the `CSIDL_LOCAL_APPDATA` directory. (Note: I'm interested in
    examples of what some windows apps use for a logs dir.)

    OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA`
    value for Windows and appends "log" to the user cache dir for Unix.
    This can be disabled with the `opinion=False` option.

HTML parsing library based on the WHATWG "HTML5"
specification. The parser is designed to be compatible with existing
HTML found in the wild and implements well-defined error recovery that
is largely compatible with modern desktop web browsers.

Example usage:

import html5lib
