43 urllib3
44 =======
45
46 urllib3 is a powerful, *sanity-friendly* HTTP client for Python. Much of the
47 Python ecosystem already uses urllib3 and you should too.
48 urllib3 brings many critical features that are missing from the Python
49 standard libraries:
50
51 - Thread safety.
52 - Connection pooling.
53 - Client-side SSL/TLS verification.
54 - File uploads with multipart encoding.
55 - Helpers for retrying requests and dealing with HTTP redirects.
56 - Support for gzip, deflate, and brotli encoding.
57 - Proxy support for HTTP and SOCKS.
58 - 100% test coverage.
59
60 urllib3 is powerful and easy to use::
61
62 >>> import urllib3
63 >>> http = urllib3.PoolManager()
64 >>> r = http.request('GET', 'http://httpbin.org/robots.txt')
65 >>> r.status
66 200
67 >>> r.data
68 'User-agent: *\nDisallow: /deny\n'
69
70
71 Installing
72 ----------
73
74 urllib3 can be installed with `pip <https://pip.pypa.io>`_::

210 (Issue #1682)
211
212
213 1.25.4 (2019-09-19)
214 -------------------
215
216 * Propagate Retry-After header settings to subsequent retries. (Pull #1607)

329
330 * Fixed bug where responses with header Content-Type: message/* erroneously
331 raised HeaderParsingError, resulting in a warning being logged. (Pull #1439)
332

336 1.23 (2018-06-04)
337 -----------------
338
339 * Allow providing a list of headers to strip from requests when redirecting
340 to a different host. Defaults to the ``Authorization`` header. Different
341 headers can be set via ``Retry.remove_headers_on_redirect``. (Issue #1316)
342

371 is available on ``MaxRetryError.reason``. (Issue #1112)
372
373 * Drain and release connection before recursing on retry/redirect. Fixes
374 deadlocks with a blocking connectionpool. (Issue #1167)

391 ``assert_hostname`` or ``assert_fingerprint`` flag to the ``PoolManager``.
392 (Pull #1157)
393
394
395 1.21 (2017-04-25)
396 -----------------
397
398 * Improved performance of certain selector system calls on Python 3.5 and
399 later. (Pull #1095)
400
401 * Resolved issue where the PyOpenSSL backend would not wrap SysCallError
402 exceptions appropriately when sending data. (Pull #1125)
403
404 * Selectors now detects a monkey-patched select module after import for modules
405 that patch the select module like eventlet, greenlet. (Pull #1128)
406
407 * Reduced memory consumption when streaming zlib-compressed responses
408 (as opposed to raw deflate streams). (Pull #1129)
409
410 * Connection pools now use the entire request context when constructing the
411 pool key. (Pull #1016)
412
413 * ``PoolManager.connection_from_*`` methods now accept a new keyword argument,
414 ``pool_kwargs``, which are merged with the existing ``connection_pool_kw``.
415 (Pull #1016)
416
417 * Add retry counter for ``status_forcelist``. (Issue #1147)
418
419 * Added ``contrib`` module for using SecureTransport on macOS:
420 ``urllib3.contrib.securetransport``. (Pull #1122)
421
422 * urllib3 now only normalizes the case of ``http://`` and ``https://`` schemes:
423 for schemes it does not recognise, it assumes they are case-sensitive and
424 leaves them unchanged.
425 (Issue #1080)
426
427
428 1.20 (2017-01-19)
429 -----------------
430

436
437 * ConnectionPools now correctly consider hostnames to be case-insensitive.
438 (Issue #1032)
439
440 * Outdated versions of PyOpenSSL now cause the PyOpenSSL contrib module
441 to fail when it is injected, rather than at first use. (Pull #1063)
442
443 * Outdated versions of cryptography now cause the PyOpenSSL contrib module
444 to fail when it is injected, rather than at first use. (Issue #1044)
445
446 * Automatically attempt to rewind a file-like body object when a request is
447 retried or redirected. (Pull #1039)
448
449 * Fix some bugs that occur when modules incautiously patch the queue module.
450 (Pull #1061)
451
452 * Prevent retries from occurring on read timeouts for which the request method
453 was not in the method whitelist. (Issue #1059)
454
455 * Changed the PyOpenSSL contrib module to lazily load idna to avoid
456 unnecessarily bloating the memory of programs that don't need it. (Pull
457 #1076)
458
459 * Add support for IPv6 literals with zone identifiers. (Pull #1013)
460
461 * Added support for socks5h:// and socks4a:// schemes when working with SOCKS
462 proxies, and controlled remote DNS appropriately. (Issue #1035)
463
464
465 1.19.1 (2016-11-16)
466 -------------------
467
468 * Fixed AppEngine import that didn't function on Python 3.5. (Pull #1025)
469
470
471 1.19 (2016-11-03)
472 -----------------
473
474 * urllib3 now respects Retry-After headers on 413, 429, and 503 responses when
475 using the default retry logic. (Pull #955)
476
477 * Remove markers from setup.py to assist ancient setuptools versions. (Issue
478 #986)
479
480 * Disallow superscripts and other integerish things in URL ports. (Issue #989)
481
482 * Allow urllib3's HTTPResponse.stream() method to continue to work with
483 non-httplib underlying FPs. (Pull #990)
484
485 * Empty filenames in multipart headers are now emitted as such, rather than
486 being suppressed. (Issue #1015)
487
488 * Prefer user-supplied Host headers on chunked uploads. (Issue #1009)
489
490
491 1.18.1 (2016-10-27)
492 -------------------
493
494 * CVE-2016-9015. Users who are using urllib3 version 1.17 or 1.18 along with
495 PyOpenSSL injection and OpenSSL 1.1.0 *must* upgrade to this version. This
496 release fixes a vulnerability whereby urllib3 in the above configuration
497 would silently fail to validate TLS certificates due to erroneously setting
498 invalid flags in OpenSSL's ``SSL_CTX_set_verify`` function. These erroneous
499 flags do not cause a problem in OpenSSL versions before 1.1.0, which
500 interprets the presence of any flag as requesting certificate validation.
501
502 There is no PR for this patch, as it was prepared for simultaneous disclosure
503 and release. The master branch received the same fix in PR #1010.
504
505
506 1.18 (2016-09-26)
507 -----------------
508
509 * Fixed incorrect message for IncompleteRead exception. (PR #973)
510
511 * Accept ``iPAddress`` subject alternative name fields in TLS certificates.
512 (Issue #258)
513
514 * Fixed consistency of ``HTTPResponse.closed`` between Python 2 and 3.
515 (Issue #977)
516
517 * Fixed handling of wildcard certificates when using PyOpenSSL. (Issue #979)
518
519
520 1.17 (2016-09-06)
521 -----------------

908
909 * New ``urllib3.connection`` module which contains all the HTTPConnection
910 objects.
911
912 * Several ``urllib3.util.Timeout``-related fixes. Also changed constructor

917
918 * Added ``.tell()`` method to ``urllib3.response.HTTPResponse`` which
919 returns the number of bytes read so far. (Issue #277)
920
921 * Support for platforms without threading. (Issue #289)
922
923 * Expand default-port comparison in ``HTTPConnectionPool.is_same_host``

944 * Headers no longer lose their case on Python 3. (Issue #236)
945
946 * ``urllib3.contrib.pyopenssl`` now uses the operating system's default CA

948
949 * Requests with ``retries=False`` will immediately raise any exceptions without
950 wrapping them in ``MaxRetryError``. (Issue #348)
951
952 * Fixed open socket leak with SSL-related failures. (Issue #344, #348)
953
954

974 file-like functionality. (Issue #187)
975
976 * Passing ``assert_hostname=False`` when creating a HTTPSConnectionPool will
977 skip hostname verification for SSL connections. (Issue #194)
978
979 * New method ``urllib3.response.HTTPResponse.stream(...)`` which acts as a
980 generator wrapped around ``.read(...)``. (Issue #198)
981
982 * IPv6 url parsing enforces brackets around the hostname. (Issue #199)
983
984 * Fixed thread race condition in
985 ``urllib3.poolmanager.PoolManager.connection_from_host(...)`` (Issue #204)
986
987 * ``ProxyManager`` requests now include non-default port in ``Host: ...``
988 header. (Issue #217)
989
990 * Added HTTPS proxy support in ``ProxyManager``. (Issue #170 #139)
991
992 * New ``RequestField`` object can be passed to the ``fields=...`` param which

994
995 * Raise ``urllib3.exceptions.ProxyError`` when connecting to proxy fails.
996 (Issue #221)
997
998 * Use international headers when posting file names. (Issue #119)

1007
1008 * ``ProxyManager`` automatically adds ``Host: ...`` header if not given.
1009
1010 * Improved SSL-related code. ``cert_req`` now optionally takes a string like
1011 "REQUIRED" or "NONE". Same with ``ssl_version`` takes strings like "SSLv23"
1012 The string values reflect the suffix of the respective constant variable.
1013 (Issue #130)
1014
1015 * Vendored ``socksipy`` now based on Anorov's fork which handles unexpectedly
1016 closed proxy connections and larger read buffers. (Issue #135)
1017
1018 * Ensure the connection is closed if no data is received, fixes connection leak
1019 on some platforms. (Issue #133)
1020
1021 * Added SNI support for SSL/TLS connections on Py32+. (Issue #89)
1022
1023 * Tests fixed to be compatible with Py26 again. (Issue #125)

1036 Section 3.5. (Issue #110)
1037
1038 * "Connection Refused" SocketErrors will get retried rather than raised.
1039 (Issue #92)
1040
1041 * Updated vendored ``six``, no longer overrides the global ``six`` module
1042 namespace. (Issue #113)
1043
1044 * ``urllib3.exceptions.MaxRetryError`` contains a ``reason`` property holding
1045 the exception that prompted the final retry. If ``reason is None`` then it
1046 was due to a redirect. (Issue #92, #114)
1047
1048 * Fixed ``PoolManager.urlopen()`` from not redirecting more than once.
1049 (Issue #149)
1050
1051 * Don't assume ``Content-Type: text/plain`` for multi-part encoding parameters
1052 that are not files. (Issue #111)
1053
1054 * Pass `strict` param down to ``httplib.HTTPConnection``. (Issue #122)
1055
1056 * Added mechanism to verify SSL certificates by fingerprint (md5, sha1) or
1057 against an arbitrary hostname (when connecting by IP or for misconfigured
1058 servers). (Issue #140)
1059
1060 * Streaming decompression support. (Issue #159)
1061
1062
1063 1.5 (2012-08-02)
1064 ----------------
1065
1066 * Added ``urllib3.add_stderr_logger()`` for quickly enabling STDERR debug
1067 logging in urllib3.
1068
1069 * Native full URL parsing (including auth, path, query, fragment) available in
1070 ``urllib3.util.parse_url(url)``.
1071
1072 * Built-in redirect will switch method to 'GET' if status code is 303.
1073 (Issue #11)
1074
1075 * ``urllib3.PoolManager`` strips the scheme and host before sending the request
1076 uri. (Issue #8)
1077
1078 * New ``urllib3.exceptions.DecodeError`` exception for when automatic decoding,
1079 based on the Content-Type header, fails.
1080
1081 * Fixed bug with pool depletion and leaking connections (Issue #76). Added
1082 explicit connection closing on pool eviction. Added
1083 ``urllib3.PoolManager.clear()``.
1084
1085 * 99% -> 100% unit test coverage.
1086
1087
1088 1.4 (2012-06-16)
1089 ----------------
1090
1091 * Minor AppEngine-related fixes.
1092
1093 * Switched from ``mimetools.choose_boundary`` to ``uuid.uuid4()``.
1094
1095 * Improved url parsing. (Issue #73)
1096
1097 * IPv6 url support. (Issue #72)
1098
1099
1100 1.3 (2012-03-25)
1101 ----------------
1102
1103 * Removed pre-1.0 deprecated API.
1104
1105 * Refactored helpers into a ``urllib3.util`` submodule.
1106
1107 * Fixed multipart encoding to support list-of-tuples for keys with multiple
1108 values. (Issue #48)
1109
1110 * Fixed multiple Set-Cookie headers in response not getting merged properly in
1111 Python 3. (Issue #53)
1112
1113 * AppEngine support with Py27. (Issue #61)
1114
1115 * Minor ``encode_multipart_formdata`` fixes related to Python 3 strings vs
1116 bytes.
1117
1118
1119 1.2.2 (2012-02-06)
1120 ------------------
1121
1122 * Fixed packaging bug of not shipping ``test-requirements.txt``. (Issue #47)
1123
1124
1125 1.2.1 (2012-02-05)
1126 ------------------
1127
1128 * Fixed another bug related to when ``ssl`` module is not available. (Issue #41)
1129
1130 * Location parsing errors now raise ``urllib3.exceptions.LocationParseError``
1131 which inherits from ``ValueError``.
1132
1133
1134 1.2 (2012-01-29)
1135 ----------------
1136
1137 * Added Python 3 support (tested on 3.2.2)
1138
1139 * Dropped Python 2.5 support (tested on 2.6.7, 2.7.2)
1140
1141 * Use ``select.poll`` instead of ``select.select`` for platforms that support
1142 it.
1143
1144 * Use ``Queue.LifoQueue`` instead of ``Queue.Queue`` for more aggressive
1145 connection reusing. Configurable by overriding ``ConnectionPool.QueueCls``.
1146
1147 * Fixed ``ImportError`` during install when ``ssl`` module is not available.
1148 (Issue #41)
1149
1150 * Fixed ``PoolManager`` redirects between schemes (such as HTTP -> HTTPS) not
1151 completing properly. (Issue #28, uncovered by Issue #10 in v1.1)
1152
1153 * Ported ``dummyserver`` to use ``tornado`` instead of ``webob`` +
1154 ``eventlet``. Removed extraneous unsupported dummyserver testing backends.
1155 Added socket-level tests.
1156
1157 * More tests. Achievement Unlocked: 99% Coverage.
1158
1159
1160 1.1 (2012-01-07)
1161 ----------------
1162
1163 * Refactored ``dummyserver`` to its own root namespace module (used for
1164 testing).
1165
1166 * Added hostname verification for ``VerifiedHTTPSConnection`` by vendoring in
1167 Py32's ``ssl_match_hostname``. (Issue #25)
1168
1169 * Fixed cross-host HTTP redirects when using ``PoolManager``. (Issue #10)
1170
1171 * Fixed ``decode_content`` being ignored when set through ``urlopen``. (Issue
1172 #27)
1173
1174 * Fixed timeout-related bugs. (Issues #17, #23)
1175
1176
1177 1.0.2 (2011-11-04)
1178 ------------------
1179
1180 * Fixed typo in ``VerifiedHTTPSConnection`` which would only present as a bug if
1181 you're using the object manually. (Thanks pyos)
1182
1183 * Made RecentlyUsedContainer (and consequently PoolManager) more thread-safe by
1184 wrapping the access log in a mutex. (Thanks @christer)
1185
1186 * Made RecentlyUsedContainer more dict-like (corrected ``__delitem__`` and
1187 ``__getitem__`` behaviour), with tests. Shouldn't affect core urllib3 code.
1188
1189
1190 1.0.1 (2011-10-10)
1191 ------------------
1192
1193 * Fixed a bug where the same connection would get returned into the pool twice,
1194 causing extraneous "HttpConnectionPool is full" log warnings.
1195
1196
1197 1.0 (2011-10-08)
1198 ----------------
1199
1200 * Added ``PoolManager`` with LRU expiration of connections (tested and
1201 documented).
1202 * Added ``ProxyManager`` (needs tests, docs, and confirmation that it works
1203 with HTTPS proxies).
1204 * Added optional partial-read support for responses when
1205 ``preload_content=False``. You can now make requests and just read the headers
1206 without loading the content.
1207 * Made response decoding optional (default on, same as before).
1208 * Added optional explicit boundary string for ``encode_multipart_formdata``.
1209 * Convenience request methods are now inherited from ``RequestMethods``. Old
1210 helpers like ``get_url`` and ``post_url`` should be abandoned in favour of
1211 the new ``request(method, url, ...)``.
1212 * Refactored code to be even more decoupled, reusable, and extendable.
1213 * License header added to ``.py`` files.
1214 * Embiggened the documentation: Lots of Sphinx-friendly docstrings in the code
1215 and docs in ``docs/`` and on https://urllib3.readthedocs.io/.
1216 * Embettered all the things!
1217 * Started writing this file.
1218
1219
1220 0.4.1 (2011-07-17)

1233
1234
1235 0.3.1 (2010-07-13)
1236 ------------------
