14# isn't available. requests unconditionally imports urllib3's socks contrib
15# module, triggering this warning. The warning breaks DEP-8 tests (because of
16# the stderr output) and is just plain annoying in normal usage. I don't want
17# to add socks as yet another dependency for pip, nor do I want to allow-stder
18# in the DEP-8 tests, so just suppress the warning. pdb tells me this has to
19# be done before the import of pip.vcs.

1"""For neatly implementing static typing in pip.
2
3`mypy` - the static type analysis tool we use - uses the `typing` module, which
4provides core functionality fundamental to mypy's functioning.
5
6Generally, `typing` would be imported at runtime and used in that fashion -
7it acts as a no-op at runtime and does not have any run-time overhead by
8design.
9
10As it turns out, `typing` is not vendorable - it uses separate sources for
11Python 2/Python 3. Thus, this codebase can not expect it to be present.
12To work around this, mypy allows the typing import to be behind a False-y
13optional to prevent it from running at runtime and type-comments can be used
14to remove the need for the types to be accessible directly during runtime.
15
16This module provides the False-y guard in a nicely named fashion so that a
17curious maintainer can reach here to read this.
18
19In pip, all static-typing related imports should be guarded as follows:
20
21 from pip.utils.typing import MYPY_CHECK_RUNNING

394 # Special case pip and setuptools to generate versioned wrappers

396 # The issue is that some projects (specifically, pip and setuptools) use
397 # code in setup.py to create "versioned" entry points - pip2.7 on Python
398 # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
399 # the wheel metadata at build time, and so if the wheel is installed with
400 # a *different* version of Python the entry points will be wrong. The
401 # correct fix for this is to enhance the metadata to be able to describe
402 # such versioned entry points, but that won't happen till Metadata 2.0 is
403 # available.
404 # In the meantime, projects using versioned entry points will either have
405 # incorrect versioned entry points, or they will not be able to distribute
406 # "universal" wheels (i.e., they will need a wheel per Python version).
407 #
408 # Because setuptools and pip are bundled with _ensurepip and virtualenv,
409 # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
410 # override the versioned entry points in the wheel and generate the
411 # correct ones. This code is purely a short-term measure until Metadata 2.0
412 # is available.
413 #

31# This prober doesn't actually recognize a language or a charset.
32# It is a helper prober for the use of the Hebrew model probers
33
34### General ideas of the Hebrew charset recognition ###
35#
36# Four main charsets exist in Hebrew:
37# "ISO-8859-8" - Visual Hebrew
38# "windows-1255" - Logical Hebrew
39# "ISO-8859-8-I" - Logical Hebrew
40# "x-mac-hebrew" - ?? Logical Hebrew ??
41#
42# Both "ISO" charsets use a completely identical set of code points, whereas
43# "windows-1255" and "x-mac-hebrew" are two different proper supersets of
44# these code points. windows-1255 defines additional characters in the range
45# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific
46# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6.
47# x-mac-hebrew defines similar additional code points but with a different
48# mapping.
49#
50# As far as an average Hebrew text with no diacritics is concerned, all four
51# charsets are identical with respect to code points. Meaning that for the
52# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters
53# (including final letters).
54#
55# The dominant difference between these charsets is their directionality.
56# "Visual" directionality means that the text is ordered as if the renderer is
57# not aware of a BIDI rendering algorithm. The renderer sees the text and
58# draws it from left to right. The text itself when ordered naturally is read
59# backwards. A buffer of Visual Hebrew generally looks like so:
60# "[last word of first line spelled backwards] [whole line ordered backwards
61# and spelled backwards] [first word of first line spelled backwards]
62# [end of line] [last word of second line] ... etc' "
63# adding punctuation marks, numbers and English text to visual text is
64# naturally also "visual" and from left to right.
65#
66# "Logical" directionality means the text is ordered "naturally" according to
67# the order it is read. It is the responsibility of the renderer to display
68# the text from right to left. A BIDI algorithm is used to place general
69# punctuation marks, numbers and English text in the text.
70#
71# Texts in x-mac-hebrew are almost impossible to find on the Internet. From
72# what little evidence I could find, it seems that its general directionality
73# is Logical.
74#
75# To sum up all of the above, the Hebrew probing mechanism knows about two
76# charsets:
77# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are
78# backwards while line order is natural. For charset recognition purposes
79# the line order is unimportant (In fact, for this implementation, even
80# word order is unimportant).
81# Logical Hebrew - "windows-1255" - normal, naturally ordered text.
82#
83# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be
84# specifically identified.
85# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew
86# that contain special punctuation marks or diacritics is displayed with
87# some unconverted characters showing as question marks. This problem might
88# be corrected using another model prober for x-mac-hebrew. Due to the fact
89# that x-mac-hebrew texts are so rare, writing another model prober isn't
90# worth the effort and performance hit.
91#
92#### The Prober ####
93#
94# The prober is divided between two SBCharSetProbers and a HebrewProber,
95# all of which are managed, created, fed data, inquired and deleted by the
96# SBCSGroupProber. The two SBCharSetProbers identify that the text is in
97# fact some kind of Hebrew, Logical or Visual. The final decision about which
98# one is it is made by the HebrewProber by combining final-letter scores
99# with the scores of the two SBCharSetProbers to produce a final answer.
100#
101# The SBCSGroupProber is responsible for stripping the original text of HTML
102# tags, English characters, numbers, low-ASCII punctuation characters, spaces
103# and new lines. It reduces any sequence of such characters to a single space.
104# The buffer fed to each prober in the SBCS group prober is pure text in
105# high-ASCII.
106# The two SBCharSetProbers (model probers) share the same language model:
107# Win1255Model.
108# The first SBCharSetProber uses the model normally as any other
109# SBCharSetProber does, to recognize windows-1255, upon which this model was
110# built. The second SBCharSetProber is told to make the pair-of-letter
111# lookup in the language model backwards. This in practice exactly simulates
112# a visual Hebrew model using the windows-1255 logical Hebrew model.
113#
114# The HebrewProber is not using any language model. All it does is look for
115# final-letter evidence suggesting the text is either logical Hebrew or visual
116# Hebrew. Disjointed from the model probers, the results of the HebrewProber
117# alone are meaningless. HebrewProber always returns 0.00 as confidence
118# since it never identifies a charset by itself. Instead, the pointer to the
119# HebrewProber is passed to the model probers as a helper "Name Prober".
120# When the Group prober receives a positive identification from any prober,
121# it asks for the name of the charset identified. If the prober queried is a
122# Hebrew model prober, the model prober forwards the call to the
123# HebrewProber to make the final decision. In the HebrewProber, the
124# decision is made according to the final-letters scores maintained and Both
125# model probers scores. The answer is returned in the form of the name of the
126# charset identified, either "windows-1255" or "ISO-8859-8".

16The ``distro`` package (``distro`` stands for Linux Distribution) provides
17information about the Linux distribution it runs on, such as a reliable
18machine-readable distro ID, or version information.
19
20It is a renewed alternative implementation for Python's original
21:py:func:`platform.linux_distribution` function, but it provides much more
22functionality. An alternative implementation became necessary because Python
233.5 deprecated this function, and Python 3.7 is expected to remove it
24altogether. Its predecessor function :py:func:`platform.dist` was already
25deprecated since Python 2.6 and is also expected to be removed in Python 3.7.
26Still, there are many cases in which access to Linux distribution information
27is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for
28more information.

191 the addition of an os-release file, or the addition of the lsb_release

1"""A collection of modules for building different kinds of trees from HTML
2documents.
3
4To create a treebuilder for a new type of tree, you need to do
5implement several things:
6
71. A set of classes for various types of elements: Document, Doctype, Comment,
8 Element. These must implement the interface of ``base.treebuilders.Node``
9 (although comment nodes have a different signature for their constructor,
10 see ``treebuilders.etree.Comment``) Textual content may also be implemented
11 as another node type, or not, as your tree implementation requires.
12
132. A treebuilder object (called ``TreeBuilder`` by convention) that inherits
14 from ``treebuilders.base.TreeBuilder``. This has 4 required attributes:
15
16 * ``documentClass`` - the class to use for the bottommost node of a document
17 * ``elementClass`` - the class to use for HTML Elements
18 * ``commentClass`` - the class to use for comments
19 * ``doctypeClass`` - the class to use for doctypes
20
21 It also has one required method:
22
23 * ``getDocument`` - Returns the root node of the complete document tree
24
253. If you wish to run the unit tests, you must also create a ``testSerializer``
26 method on your treebuilder which accepts a node and returns a string
27 containing Node and its children serialized according to the format used in
28 the unittests

3Package resource API
4--------------------
5
6A resource is a logical file contained within a package, or a logical
7subdirectory thereof. The package resource API expects resource names
8to have their path parts separated with ``/``, *not* whatever the local
9path separator is. Do not use os.path operations to manipulate resource
10names being passed into the API.
11
12The package resource API is designed to work with normal filesystem packages,
13.egg files, and unpacked .egg files. It can also work in a limited way with
14.zip files and with custom PEP 302 loaders that support the ``get_data()``
15method.

27pyparsing module - Classes and methods to define and execute parsing grammars
28
29The pyparsing module is an alternative approach to creating and executing simple grammars,
30vs. the traditional lex/yacc approach, or the use of regular expressions. With pyparsing, you
31don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
32provides a library of classes that you use to construct the grammar directly in Python.
33
34Here is a program to parse "Hello, World!" (or any greeting of the form
35C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements
36(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
37L{Literal} expressions)::
38
39 from pip._vendor.pyparsing import Word, alphas
40
41 # define grammar of a greeting
42 greet = Word(alphas) + "," + Word(alphas) + "!"
43
44 hello = "Hello, World!"
45 print (hello, "->", greet.parseString(hello))
46
47The program outputs the following::
48
49 Hello, World! -> ['Hello', ',', 'World', '!']
50
51The Python representation of the grammar is quite readable, owing to the self-explanatory
52class names, and the use of '+', '|' and '^' operators.
53
54The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
55object with named attributes.
56
57The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
58 - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.)
59 - quoted strings
60 - embedded comments

1554 Repeated parse attempts at the same string location (which happens
1555 often in many complex grammars) can immediately return a cached value,
1556 instead of re-executing parsing/validating code. Memoizing is done of
1557 both valid results and parsing exceptions.

1562 the cache size will be unbounded; if 0 is passed, the cache will
1563 be effectively disabled.
1564
1565 This speedup may break existing programs that use parse actions that
1566 have side-effects. For this reason, packrat parsing is disabled when
1567 you first import pyparsing. To activate the packrat feature, your
1568 program must call the class method C{ParserElement.enablePackrat()}. If
1569 your program uses C{psyco} to "compile as you go", you must call
1570 C{enablePackrat} before calling C{psyco.full()}. If you do not do this,
1571 Python will crash. For best results, call C{enablePackrat()} immediately
1572 after importing pyparsing.

2585 """
2586 Token for matching words composed of allowed character sets.
2587 Defined with string containing all allowed initial characters,
2588 an optional string containing allowed body characters (if omitted,
2589 defaults to the initial character set), and an optional minimum,
2590 maximum, and/or exact length. The default value for C{min} is 1 (a
2591 minimum value < 1 is not valid); the default values for C{max} and C{exact}
2592 are 0, meaning no maximum or exact length restriction. An optional
2593 C{excludeChars} parameter can list characters that might be found in
2594 the input C{bodyChars} string; useful to define a word of all printables
2595 except for one or two characters, for instance.
2596
2597 L{srange} is useful for defining custom character set strings for defining
2598 C{Word} expressions, using range notation from regular expression character sets.
2599
2600 A common mistake is to use C{Word} to match a specific literal string, as in
2601 C{Word("Address")}. Remember that C{Word} uses the string argument to define
2602 I{sets} of matchable characters. This expression would match "Add", "AAA",
2603 "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
2604 To match an exact literal string, use L{Literal} or L{Keyword}.
2605
2606 pyparsing includes helper strings for building Words:
2607 - L{alphas}
2608 - L{nums}
2609 - L{alphanums}
2610 - L{hexnums}
2611 - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
2612 - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
2613 - L{printables} (any non-whitespace character)
2614
2615 Example::
2616 # a word composed of digits
2617 integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
2618
2619 # a word with a leading capital, and zero or more lowercase
2620 capital_word = Word(alphas.upper(), alphas.lower())

5024 mechanism to potentially improve your parser performance.
5025
5026 Parameters:
5027 - baseExpr - expression representing the most basic element for the nested
5028 - opList - list of tuples, one for each operator precedence level in the
5029 expression grammar; each tuple is of the form
5030 (opExpr, numTerms, rightLeftAssoc, parseAction), where:
5031 - opExpr is the pyparsing expression for the operator;
5032 may also be a string, which will be converted to a Literal;
5033 if numTerms is 3, opExpr is a tuple of two expressions, for the
5034 two operators separating the 3 terms
5035 - numTerms is the number of terms for this operator (must
5036 be 1, 2, or 3)
5037 - rightLeftAssoc is the indicator whether the operator is
5038 right or left associative, using the pyparsing-defined
5039 constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
5040 - parseAction is the parse action to be associated with
5041 expressions matching this operator expression (the
5042 parse action tuple member may be omitted); if the parse action
5043 is passed a tuple or list of functions, this is equivalent to
5044 calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})
5045 - lpar - expression for matching left-parentheses (default=C{Suppress('(')})
5046 - rpar - expression for matching right-parentheses (default=C{Suppress(')')})

9Requests HTTP Library
10~~~~~~~~~~~~~~~~~~~~~
11
12Requests is an HTTP library, written in Python, for human beings. Basic GET
13usage:
14
15 >>> import requests
16 >>> r = requests.get('https://www.python.org')
17 >>> r.status_code
18 200
19 >>> 'Python is a programming language' in r.content
20 True
21
22... or POST:
23
24 >>> payload = dict(key1='value1', key2='value2')
25 >>> r = requests.post('http://httpbin.org/post', data=payload)
26 >>> print(r.text)
27 {
28 ...
29 "form": {
30 "key2": "value2",
31 "key1": "value1"
32 },
33 ...
34 }
35
36The other HTTP methods are supported - see `requests.api`. Full documentation
37is at <http://python-requests.org>.

108 Additional field-value pairs to pass in to ``dict.update``.

110 A ``dict`` like container for storing HTTP Headers.
111
112 Field names are stored and compared case-insensitively in compliance with
113 RFC 7230. Iteration provides the first case-sensitive key seen for each
114 case-insensitive pair.
115
116 Using ``__setitem__`` syntax overwrites fields that compare equal
117 case-insensitively in order to maintain ``dict``'s api. For fields that
118 compare equal, instead create a new ``HTTPHeaderDict`` and use ``.add``
119 in a loop.
120
121 If multiple fields that are equal case-insensitively are passed to the
122 constructor or ``.update``, the behavior is undefined and some will be
123 lost.

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

489 but no other types of errors. Pass zero to never retry.

492 immediately. Also, instead of raising a MaxRetryError on redirects,
493 the redirect response will be returned.
494
495 :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.

498 If True, automatically handle redirects (status codes 301, 302,
499 303, 307, 308). Each redirect counts as a retry. Disabling retries
500 will disable redirect, too.

503 If ``True``, will make sure that the host of the pool requests is
504 consistent else will raise HostChangedError. When False, you can
505 use the pool on an HTTP proxy and request foreign hosts.

508 If specified, overrides the default timeout for this one
509 request. It may be a float (in seconds) or an instance of
510 :class:`urllib3.util.Timeout`.
511
512 :param pool_timeout:
513 If set and the pool is set to block=True, then this method will
514 block for ``pool_timeout`` seconds and raise EmptyPoolError if no
515 connection is available within the time period.

518 If False, then the urlopen call will not release the connection
519 back into the pool once a response is received (but will release if
520 you read the entire contents of the response such as when
521 `preload_content=True`). This is useful if you're not preloading
522 the response's content immediately. You will need to call
523 ``r.release_conn()`` on the response ``r`` to return the connection
524 back into the pool. If None, it takes the value of
525 ``response_kw.get('preload_content', True)``.
526
527 :param chunked:
528 If True, urllib3 will send the body using chunked transfer
529 encoding. Otherwise, urllib3 will send the body using the standard
530 content-length form. Defaults to False.
531
532 :param int body_pos:
533 Position to seek to in file-like body in the event of a retry or

4SecureTransport. These are essentially the C-level functions and constants, and

2This module provides a pool manager that uses Google App Engine's
3`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
4
5Example usage::
6
7 from pip._vendor.urllib3 import PoolManager
8 from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
9
10 if is_appengine_sandbox():
11 # AppEngineManager uses AppEngine's URLFetch API behind the scenes
12 http = AppEngineManager()
13 else:
14 # PoolManager uses a socket-level API behind the scenes
15 http = PoolManager()
16
17 r = http.request('GET', 'https://google.com/')
18
19There are `limitations <https://cloud.google.com/appengine/docs/python/\
20urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
21the best choice for your application. There are three options for using
22urllib3 on Google App Engine:
23
241. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
25 cost-effective in many circumstances as long as your usage is within the
26 limitations.
272. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
28 Sockets also have `limitations and restrictions
29 <https://cloud.google.com/appengine/docs/python/sockets/\
30 #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
31 To use sockets, be sure to specify the following in your ``app.yaml``::
32
33 env_variables:
34 GAE_USE_SOCKETS_HTTPLIB : 'true'
35
363. If you are using `App Engine Flexible
37<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
38:class:`PoolManager` without any configuration or special environment variables.

2SSL with SNI_-support for Python 2. Follow these instructions if you would
3like to verify SSL certificates in Python 2. Note, the default libraries do
4*not* do certificate checking; you need to do additional work to validate
5certificates yourself.
6
7This needs the following packages installed:
8
9* pyOpenSSL (tested with 16.0.0)
10* cryptography (minimum 1.3.4, from pyopenssl)
11* idna (minimum 2.0, from cryptography)
12
13However, pyopenssl depends on cryptography, which depends on idna, so while we
14use all three directly here we end up having relatively few packages required.
15
16You can install them with the following command:
17
18 pip install pyopenssl cryptography idna
19
20To activate certificate checking, call
21:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
22before you begin making HTTP requests. This can be done in a ``sitecustomize``
23module, or at any other time before your application begins using ``urllib3``,
24like this::
25
26 try:
27 import urllib3.contrib.pyopenssl
28 urllib3.contrib.pyopenssl.inject_into_urllib3()
29 except ImportError:
30 pass
31
32Now you can use :mod:`urllib3` as you normally would, and it will support SNI
33when the required modules are installed.
34
35Activating this module also has the positive side effect of disabling SSL/TLS
36compression in Python 2 (see `CRIME attack`_).
37
38If you want to configure the default list of supported cipher suites, you can
39set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

2SecureTranport support for urllib3 via ctypes.
3
4This makes platform-native TLS available to urllib3 users on macOS without the
5use of a compiler. This is an important feature because the Python Package
6Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
7that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
8this is to give macOS users an alternative solution to the problem, and that
9solution is to use SecureTransport.
10
11We use ctypes here because this solution must not require a compiler. That's
12because pip is not allowed to require a compiler either.
13
14This is not intended to be a seriously long-term solution to this problem.
15The hope is that PEP 543 will eventually solve this issue for us, at which
16point we can retire this contrib module. But in the short term, we need to
17solve the impending tire fire that is Python on Mac without this kind of
18contrib module. So...here we are.
19
20To use this module, simply import and inject it::
21
22 import urllib3.contrib.securetransport
23 urllib3.contrib.securetransport.inject_into_urllib3()

2"""
3This module contains provisional support for SOCKS proxies from within
4urllib3. This module supports SOCKS4 (specifically the SOCKS4A variant) and
5SOCKS5. To enable its functionality, either install PySocks or install this
6module with the ``socks`` extra.
7
8The SOCKS implementation supports the full range of urllib3 features. It also
9supports the following SOCKS features:
10
11- SOCKS4
12- SOCKS4a
13- SOCKS5
14- Usernames and passwords for the SOCKS proxy
15
16Known Limitations:
17
18- Currently PySocks does not support contacting remote websites via literal
19 IPv6 addresses. Any such connection attempt will fail. You must use a domain
20 name.
21- Currently PySocks does not support IPv6 connections to the SOCKS proxy. Any
22 such connection attempt will fail.

119 When uploading a file, providing a filename (the first parameter of the

51 Total number of retries to allow. Takes precedence over other counts.
52
53 Set to ``None`` to remove this constraint and fall back on other
54 counts. It's a good idea to set this to some sensibly-high value to
55 account for unexpected edge cases and avoid infinite retry loops.
56
57 Set to ``0`` to fail on the first retry.
58
59 Set to ``False`` to disable and imply ``raise_on_redirect=False``.
60
61 :param int connect:
62 How many connection-related errors to retry on.
63
64 These are errors raised before the request is sent to the remote server,
65 which we assume has not triggered the server to process the request.
66

68

101 same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.

103 Set to a ``False`` value to retry on any verb.
104
105 :param iterable status_forcelist:
106 A set of integer HTTP status codes that we should force a retry on.
107 A retry is initiated if the request method is in ``method_whitelist``
108 and the response status code is in ``status_forcelist``.
109
110 By default, this is disabled with ``None``.

113 A backoff factor to apply between attempts after the second try
114 (most errors are resolved immediately by a second try without a
115 delay). urllib3 will sleep for::
116
117 {backoff factor} * (2 ^ ({number of total retries} - 1))

119 seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep

127 response code in the 3xx range.

130 whether we should raise an exception, or return a response,

48 The maximum amount of time to wait for a connection attempt to a server

57 The maximum amount of time to wait between consecutive

67
68 Many factors can affect the total amount of time for urllib3 to return
69 an HTTP response.
70
71 For example, Python's DNS resolver does not obey the timeout specified
72 on the socket. Other factors that can affect total request time include
73 high CPU load, high swap, the program running at a low priority level,
74 or other behaviors.
75
76 In addition, the read and total timeouts only measure the time between
77 read operations on the socket connecting the client and the server,
78 not the total amount of time for the request to return a complete
79 response. For most requests, the timeout is raised because the server
80 has not sent the first byte in the specified time. This is not always
81 the case; if a server streams one byte every fifteen seconds, a timeout
82 of 20 seconds will not trigger, even though the request will take
83 several minutes to complete.
84
85 If your goal is to cut off any request after a set amount of wall clock
86 time, consider having a second "watcher" thread to cut off a slow
87 request.
