For example, it + is impossible to tell whether the server will close the connection + UNTIL the response headers have been read; this means that further + requests cannot be placed into the pipeline until it is known that + the server will NOT be closing the connection. + +Logical State __state __response +------------- ------- ---------- +Idle _CS_IDLE None +Request-started _CS_REQ_STARTED None +Request-sent _CS_REQ_SENT None +Unread-response _CS_IDLE +Req-started-unread-response _CS_REQ_STARTED +Req-sent-unread-response _CS_REQ_SENT +""" + +from __future__ import (absolute_import, division, + print_function, unicode_literals) +from future.builtins import bytes, int, str, super +from future.utils import PY2 + +from future.backports.email import parser as email_parser +from future.backports.email import message as email_message +from future.backports.misc import create_connection as socket_create_connection +import io +import os +import socket +import collections +from future.backports.urllib.parse import urlsplit +import warnings +from array import array + +__all__ = ["HTTPResponse", "HTTPConnection", + "HTTPException", "NotConnected", "UnknownProtocol", + "UnknownTransferEncoding", "UnimplementedFileMode", + "IncompleteRead", "InvalidURL", "ImproperConnectionState", + "CannotSendRequest", "CannotSendHeader", "ResponseNotReady", + "BadStatusLine", "error", "responses"] + +HTTP_PORT = 80 +HTTPS_PORT = 443 + +_UNKNOWN = 'UNKNOWN' + +# connection states +_CS_IDLE = 'Idle' +_CS_REQ_STARTED = 'Request-started' +_CS_REQ_SENT = 'Request-sent' + +# status codes +# informational +CONTINUE = 100 +SWITCHING_PROTOCOLS = 101 +PROCESSING = 102 + +# successful +OK = 200 +CREATED = 201 +ACCEPTED = 202 +NON_AUTHORITATIVE_INFORMATION = 203 +NO_CONTENT = 204 +RESET_CONTENT = 205 +PARTIAL_CONTENT = 206 +MULTI_STATUS = 207 +IM_USED = 226 + +# redirection +MULTIPLE_CHOICES = 300 +MOVED_PERMANENTLY = 301 +FOUND = 302 +SEE_OTHER = 303 +NOT_MODIFIED = 304 +USE_PROXY = 305 +TEMPORARY_REDIRECT = 307 + +# client error +BAD_REQUEST = 400 +UNAUTHORIZED = 401 +PAYMENT_REQUIRED = 402 +FORBIDDEN = 403 +NOT_FOUND = 404 +METHOD_NOT_ALLOWED = 405 +NOT_ACCEPTABLE = 406 +PROXY_AUTHENTICATION_REQUIRED = 407 +REQUEST_TIMEOUT = 408 +CONFLICT = 409 +GONE = 410 +LENGTH_REQUIRED = 411 +PRECONDITION_FAILED = 412 +REQUEST_ENTITY_TOO_LARGE = 413 +REQUEST_URI_TOO_LONG = 414 +UNSUPPORTED_MEDIA_TYPE = 415 +REQUESTED_RANGE_NOT_SATISFIABLE = 416 +EXPECTATION_FAILED = 417 +UNPROCESSABLE_ENTITY = 422 +LOCKED = 423 +FAILED_DEPENDENCY = 424 +UPGRADE_REQUIRED = 426 +PRECONDITION_REQUIRED = 428 +TOO_MANY_REQUESTS = 429 +REQUEST_HEADER_FIELDS_TOO_LARGE = 431 + +# server error +INTERNAL_SERVER_ERROR = 500 +NOT_IMPLEMENTED = 501 +BAD_GATEWAY = 502 +SERVICE_UNAVAILABLE = 503 +GATEWAY_TIMEOUT = 504 +HTTP_VERSION_NOT_SUPPORTED = 505 +INSUFFICIENT_STORAGE = 507 +NOT_EXTENDED = 510 +NETWORK_AUTHENTICATION_REQUIRED = 511 + +# Mapping status codes to official W3C names +responses = { + 100: 'Continue', + 101: 'Switching Protocols', + + 200: 'OK', + 201: 'Created', + 202: 'Accepted', + 203: 'Non-Authoritative Information', + 204: 'No Content', + 205: 'Reset Content', + 206: 'Partial Content', + + 300: 'Multiple Choices', + 301: 'Moved Permanently', + 302: 'Found', + 303: 'See Other', + 304: 'Not Modified', + 305: 'Use Proxy', + 306: '(Unused)', + 307: 'Temporary Redirect', + + 400: 'Bad Request', + 401: 'Unauthorized', + 402: 'Payment Required', + 403: 'Forbidden', + 404: 'Not Found', + 405: 'Method Not Allowed', + 406: 'Not Acceptable', + 407: 'Proxy Authentication Required', + 408: 'Request Timeout', + 409: 'Conflict', + 410: 'Gone', + 411: 'Length Required', + 412: 'Precondition Failed', + 413: 'Request Entity Too Large', + 414: 'Request-URI Too Long', + 415: 'Unsupported Media Type', + 416: 'Requested Range Not Satisfiable', + 417: 'Expectation Failed', + 428: 'Precondition Required', + 429: 'Too Many Requests', + 431: 'Request Header Fields Too Large', + + 500: 'Internal Server Error', + 501: 'Not Implemented', + 502: 'Bad Gateway', + 503: 'Service Unavailable', + 504: 'Gateway Timeout', + 505: 'HTTP Version Not Supported', + 511: 'Network Authentication Required', +} + +# maximal amount of data to read at one time in _safe_read +MAXAMOUNT = 1048576 + +# maximal line length when calling readline(). +_MAXLINE = 65536 +_MAXHEADERS = 100 + + +class HTTPMessage(email_message.Message): + # XXX The only usage of this method is in + # http.server.CGIHTTPRequestHandler.

This is the +default behavior. You can change the header and printed +attributes by using the .output() function + + >>> C = cookies.SimpleCookie() + >>> C["rocky"] = "road" + >>> C["rocky"]["path"] = "/cookie" + >>> print(C.output(header="Cookie:")) + Cookie: rocky=road; Path=/cookie + >>> print(C.output(attrs=[], header="Cookie:")) + Cookie: rocky=road + +The load() method of a Cookie extracts cookies from a string. In a +CGI script, you would use this method to extract the cookies from the +HTTP_COOKIE environment variable. + + >>> C = cookies.SimpleCookie() + >>> C.load("chips=ahoy; vienna=finger") + >>> C.output() + 'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger' + +The load() method is darn-tootin smart about identifying cookies +within a string. Escaped quotation marks, nested semicolons, and other +such trickeries do not confuse it. + + >>> C = cookies.SimpleCookie() + >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";') + >>> print(C) + Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;" + +Each element of the Cookie also supports all of the RFC 2109 +Cookie attributes.

For +instance, a threading UDP server class is created as follows: + + class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass + +The Mix-in class must come first, since it overrides a method defined +in UDPServer! Setting the various member variables also changes +the behavior of the underlying server mechanism. + +To implement a service, you must derive a class from +BaseRequestHandler and redefine its handle() method. You can then run +various versions of the service by combining one of the server classes +with your request handler class. + +The request handler class must be different for datagram or stream +services. This can be hidden by using the request handler +subclasses StreamRequestHandler or DatagramRequestHandler. + +Of course, you still have to use your head! + +For instance, it makes no sense to use a forking server if the service +contains state in memory that can be modified by requests (since the +modifications in the child process would never reach the initial state +kept in the parent process and passed to each child). In this case, +you can use a threading server, but you will probably have to use +locks to avoid two requests that come in nearly simultaneous to apply +conflicting changes to the server state. + +On the other hand, if you are building e.g. an HTTP server, where all +data is stored externally (e.g. in the file system), a synchronous +class will essentially render the service "deaf" while one request is +being handled -- which may be for a very long time if a client is slow +to read all the data it has requested. Here a threading or forking +server is appropriate. + +In some cases, it may be appropriate to process part of a request +synchronously, but to finish processing in a forked child depending on +the request data. This can be implemented by using a synchronous +server and doing an explicit fork in the request handler class +handle() method. + +Another approach to handling multiple simultaneous requests in an +environment that supports neither threads nor fork (or where these are +too expensive or inappropriate for the service) is to maintain an +explicit table of partially finished requests and to use select() to +decide which request to work on next (or whether to handle a new +incoming request).

The temporary socket is + then closed and deleted, and the ephemeral port is returned. + + Either this method or bind_port() should be used for any tests where a + server socket needs to be bound to a particular port for the duration of + the test. Which one to use depends on whether the calling code is creating + a python socket, or if an unused port needs to be provided in a constructor + or passed to an external program (i.e. the -accept argument to openssl's + s_server mode). Always prefer bind_port() over find_unused_port() where + possible. Hard coded ports should *NEVER* be used. As soon as a server + socket is bound to a hard coded port, the ability to run multiple instances + of the test simultaneously on the same host is compromised, which makes the + test a ticking time bomb in a buildbot environment. On Unix buildbots, this + may simply manifest as a failed test, which can be recovered from without + intervention in most cases, but on Windows, the entire python process can + completely and utterly wedge, requiring someone to log in to the buildbot + and manually kill the affected process. + + (This is easy to reproduce on Windows, unfortunately, and can be traced to + the SO_REUSEADDR socket option having different semantics on Windows versus + Unix/Linux. On Unix, you can't have two AF_INET SOCK_STREAM sockets bind, + listen and then accept connections on identical host/ports. An EADDRINUSE + socket.error will be raised at some point (depending on the platform and + the order bind and listen were called on each socket). + + However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE + will ever be raised when attempting to bind two identical host/ports. When + accept() is called on each socket, the second caller's process will steal + the port from the first caller, leaving them both in an awkwardly wedged + state where they'll no longer respond to any signals or graceful kills, and + must be forcibly killed via OpenProcess()/TerminateProcess(). + + The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option + instead of SO_REUSEADDR, which effectively affords the same semantics as + SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open + Source world compared to Windows ones, this is a common mistake. A quick + look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when + openssl.exe is called with the 's_server' option, for example.

It opens the URL and returns the results as file-like +object; the returned object has some extra methods described below. + +The OpenerDirector manages a collection of Handler objects that do +all the actual work. Each Handler implements a particular protocol or +option. The OpenerDirector is a composite object that invokes the +Handlers needed to open the requested URL. For example, the +HTTPHandler performs HTTP GET and POST requests and deals with +non-error returns. The HTTPRedirectHandler automatically deals with +HTTP 301, 302, 303 and 307 redirect errors, and the HTTPDigestAuthHandler +deals with digest authentication. + +urlopen(url, data=None) -- Basic usage is the same as original +urllib. pass the url and optionally data to post to an HTTP URL, and +get a file-like object back. One difference is that you can also pass +a Request instance instead of URL.

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 + + +Getting Started - +----------------- +Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing +classes inherit from. Use the docstrings for examples of how to: + - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes + - construct character word-group expressions using the L{Word} class + - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes + - use L{'+'}, L{'|'}, L{'^'}, and L{'&'} operators to combine simple expressions into more complex ones + - associate names with your parsed results using L{ParserElement.setResultsName} + - find some helpful expression short-cuts like L{delimitedList} and L{oneOf} + - find more useful common expressions in the L{pyparsing_common} namespace class +""" + +__version__ = "2.2.2" +__versionTime__ = "29 Sep 2018 15:58 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: + # Python 3 + from collections.abc import Iterable + from collections.abc import MutableMapping +except ImportError: + # Python 2.7 + from collections import Iterable + from collections import MutableMapping + +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.
