Changelog

Changelog

1.22

* Fixed missing brackets in ``HTTP CONNECT`` when connecting to IPv6 address via
IPv6 proxy. (Issue 1222)

* Made the connection pool retry on ``SSLError``.  The original ``SSLError``
is available on ``MaxRetryError.reason``. (Issue 1112)

* Drain and release connection before recursing on retry/redirect.  Fixes
deadlocks with a blocking connectionpool. (Issue 1167)

* Fixed compatibility for cookiejar. (Issue 1229)

* pyopenssl: Use vendored version of ``six``. (Issue 1231)```



### 1.21.1
```-------------------

* Fixed SecureTransport issue that would cause long delays in response body
delivery. (Pull 1154)

* Fixed regression in 1.21 that threw exceptions when users passed the
``socket_options`` flag to the ``PoolManager``.  (Issue 1165)

* Fixed regression in 1.21 that threw exceptions when users passed the
``assert_hostname`` or ``assert_fingerprint`` flag to the ``PoolManager``.
(Pull 1157)```



### 1.21
```-----------------

* Improved performance of certain selector system calls on Python 3.5 and
later. (Pull 1095)

* Resolved issue where the PyOpenSSL backend would not wrap SysCallError
exceptions appropriately when sending data. (Pull 1125)

* Selectors now detects a monkey-patched select module after import for modules
that patch the select module like eventlet, greenlet. (Pull 1128)

* Reduced memory consumption when streaming zlib-compressed responses
(as opposed to raw deflate streams). (Pull 1129)

* Connection pools now use the entire request context when constructing the
pool key. (Pull 1016)

* ``PoolManager.connection_from_*`` methods now accept a new keyword argument,
``pool_kwargs``, which are merged with the existing ``connection_pool_kw``.
(Pull 1016)

* Add retry counter for ``status_forcelist``. (Issue 1147)

* Added ``contrib`` module for using SecureTransport on macOS:
``urllib3.contrib.securetransport``.  (Pull 1122)

* urllib3 now only normalizes the case of ``http://`` and ``https://`` schemes:
for schemes it does not recognise, it assumes they are case-sensitive and
leaves them unchanged.
(Issue 1080)```



### 1.20
```-----------------

* Added support for waiting for I/O using selectors other than select,
improving urllib3's behaviour with large numbers of concurrent connections.
(Pull 1001)

* Updated the date for the system clock check. (Issue 1005)

* ConnectionPools now correctly consider hostnames to be case-insensitive.
(Issue 1032)

* Outdated versions of PyOpenSSL now cause the PyOpenSSL contrib module
to fail when it is injected, rather than at first use. (Pull 1063)

* Outdated versions of cryptography now cause the PyOpenSSL contrib module
to fail when it is injected, rather than at first use. (Issue 1044)

* Automatically attempt to rewind a file-like body object when a request is
retried or redirected. (Pull 1039)

* Fix some bugs that occur when modules incautiously patch the queue module.
(Pull 1061)

* Prevent retries from occuring on read timeouts for which the request method
was not in the method whitelist. (Issue 1059)

* Changed the PyOpenSSL contrib module to lazily load idna to avoid
unnecessarily bloating the memory of programs that don't need it. (Pull
1076)

* Add support for IPv6 literals with zone identifiers. (Pull 1013)

* Added support for socks5h:// and socks4a:// schemes when working with SOCKS
proxies, and controlled remote DNS appropriately. (Issue 1035)```



### 1.19.1
```-------------------

* Fixed AppEngine import that didn't function on Python 3.5. (Pull 1025)```



### 1.19
```-----------------

* urllib3 now respects Retry-After headers on 413, 429, and 503 responses when
using the default retry logic. (Pull 955)

* Remove markers from setup.py to assist ancient setuptools versions. (Issue
986)

* Disallow superscripts and other integerish things in URL ports. (Issue 989)

* Allow urllib3's HTTPResponse.stream() method to continue to work with
non-httplib underlying FPs. (Pull 990)

* Empty filenames in multipart headers are now emitted as such, rather than
being supressed. (Issue 1015)

* Prefer user-supplied Host headers on chunked uploads. (Issue 1009)```



### 1.18.1
```-------------------

* CVE-2016-9015. Users who are using urllib3 version 1.17 or 1.18 along with
PyOpenSSL injection and OpenSSL 1.1.0 *must* upgrade to this version. This
release fixes a vulnerability whereby urllib3 in the above configuration
would silently fail to validate TLS certificates due to erroneously setting
invalid flags in OpenSSL's ``SSL_CTX_set_verify`` function. These erroneous
flags do not cause a problem in OpenSSL versions before 1.1.0, which
interprets the presence of any flag as requesting certificate validation.

There is no PR for this patch, as it was prepared for simultaneous disclosure
and release. The master branch received the same fix in PR 1010.```



### 1.18
```-----------------

* Fixed incorrect message for IncompleteRead exception. (PR 973)

* Accept ``iPAddress`` subject alternative name fields in TLS certificates.
(Issue 258)

* Fixed consistency of ``HTTPResponse.closed`` between Python 2 and 3.
(Issue 977)

* Used URLFetch default timeout on AppEngine, rather than hardcoding our own.
(Issue 858)

* Normalize the scheme and host in the URL parser (Issue 833)

* ``HTTPResponse`` contains the last ``Retry`` object, which now also
contains retries history. (Issue 848)

* Timeout can no longer be set as boolean, and must be greater than zero.
(PR 924)

* Removed pyasn1 and ndg-httpsclient from dependencies used for PyOpenSSL. We
now use cryptography and idna, both of which are already dependencies of
PyOpenSSL. (PR 930)

* Fixed infinite loop in ``stream`` when amt=None. (Issue 928)

* Try to use the operating system's certificates when we are using an
``SSLContext``. (PR 941)

* Updated cipher suite list to allow ChaCha20+Poly1305. AES-GCM is preferred to
ChaCha20, but ChaCha20 is then preferred to everything else. (PR 947)

* Updated cipher suite list to remove 3DES-based cipher suites. (PR 958)

* Removed the cipher suite fallback to allow HIGH ciphers. (PR 958)

* Implemented ``length_remaining`` to determine remaining content
to be read. (PR 949)

* Implemented ``enforce_content_length`` to enable exceptions when
incomplete data chunks are received. (PR 949)

* Dropped connection start, dropped connection reset, redirect, forced retry,
and new HTTPS connection log levels to DEBUG, from INFO. (PR 967)```



### 1.16
```-----------------

* Disable IPv6 DNS when IPv6 connections are not possible. (Issue 840)

called by subclasses. (Issue 873)

* Retain ``release_conn`` state across retries. (Issues 651, 866)

* Add customizable ``HTTPConnectionPool.ResponseCls``, which defaults to
``HTTPResponse`` but can be replaced with a subclass. (Issue 879)```



### 1.15.1
```-------------------

* Fix packaging to include backports module. (Issue 841)```



### 1.15

### 1.9
```----------------

* Shuffled around development-related files. If you're maintaining a distro
package of urllib3, you may need to tweak things. (Issue 415)

* Unverified HTTPS requests will trigger a warning on the first request. See
our new `security documentation
<https://urllib3.readthedocs.io/en/latest/security.html>`_ for details.
(Issue 426)

* Fixed proxy-related bug where connections were being reused incorrectly.
(Issues 366, 369)

* Added ``socket_options`` keyword parameter which allows to define
``setsockopt`` configuration of new sockets. (Issue 397)

* Removed ``HTTPConnection.tcp_nodelay`` in favor of
``HTTPConnection.default_socket_options``. (Issue 397)

* Fixed ``TypeError`` bug in Python 2.6.4. (Issue 411)```



### 1.8.2
```------------------

* Fix ``urllib3.util`` not being included in the package.```



### 1.8.1
```------------------

* Fix AppEngine bug of HTTPS requests going out as HTTP. (Issue 356)

* Don't install ``dummyserver`` into ``site-packages`` as it's only needed
for the test suite. (Issue 362)

* Added support for specifying ``source_address``. (Issue 352)```



### 1.8
```----------------

* Improved url parsing in ``urllib3.util.parse_url`` (properly parse '' in
username, and blank ports like 'hostname:').

* New ``urllib3.connection`` module which contains all the HTTPConnection
objects.

* Several ``urllib3.util.Timeout``-related fixes. Also changed constructor
signature to a more sensible order. [Backwards incompatible]
(Issues 252, 262, 263)

* Use ``backports.ssl_match_hostname`` if it's installed. (Issue 274)

* Added ``.tell()`` method to ``urllib3.response.HTTPResponse`` which
returns the number of bytes read so far. (Issue 277)

* Support for platforms without threading. (Issue 289)

* Expand default-port comparison in ``HTTPConnectionPool.is_same_host``
to allow a pool with no specified port to be considered equal to to an
HTTP/HTTPS url with port 80/443 explicitly provided. (Issue 305)

* Improved default SSL/TLS settings to avoid vulnerabilities.
(Issue 309)

* Fixed ``urllib3.poolmanager.ProxyManager`` not retrying on connect errors.
(Issue 310)

* Disable Nagle's Algorithm on the socket for non-proxies. A subset of requests
will send the entire HTTP request ~200 milliseconds faster; however, some of
the resulting TCP packets will be smaller. (Issue 254)

* Increased maximum number of SubjectAltNames in ``urllib3.contrib.pyopenssl``
from the default 64 to 1024 in a single certificate. (Issue 318)

* Headers are now passed and stored as a custom
``urllib3.collections_.HTTPHeaderDict`` object rather than a plain ``dict``.
(Issue 329, 333)

* Headers no longer lose their case on Python 3. (Issue 236)

* ``urllib3.contrib.pyopenssl`` now uses the operating system's default CA
certificates on inject. (Issue 332)

### 1.7
```----------------

* More exceptions are now pickle-able, with tests. (Issue 174)

* Fixed redirecting with relative URLs in Location header. (Issue 178)

* Support for relative urls in ``Location: ...`` header. (Issue 179)

* ``urllib3.response.HTTPResponse`` now inherits from ``io.IOBase`` for bonus
file-like functionality. (Issue 187)

* Passing ``assert_hostname=False`` when creating a HTTPSConnectionPool will
skip hostname verification for SSL connections. (Issue 194)

* New method ``urllib3.response.HTTPResponse.stream(...)`` which acts as a
generator wrapped around ``.read(...)``. (Issue 198)

* IPv6 url parsing enforces brackets around the hostname. (Issue 199)

* Fixed thread race condition in
``urllib3.poolmanager.PoolManager.connection_from_host(...)`` (Issue 204)

* ``ProxyManager`` requests now include non-default port in ``Host: ...``
header. (Issue 217)

```----------------

* Contrib: Optional SNI support for Py2 using PyOpenSSL. (Issue 156)

* ``ProxyManager`` automatically adds ``Host: ...`` header if not given.

* Improved SSL-related code. ``cert_req`` now optionally takes a string like
"REQUIRED" or "NONE". Same with ``ssl_version`` takes strings like "SSLv23"
The string values reflect the suffix of the respective constant variable.
(Issue 130)

* Vendored ``socksipy`` now based on Anorov's fork which handles unexpectedly
closed proxy connections and larger read buffers. (Issue 135)

* Ensure the connection is closed if no data is received, fixes connection leak
on some platforms. (Issue 133)

* Added SNI support for SSL/TLS connections on Py32+. (Issue 89)

* Tests fixed to be compatible with Py26 again. (Issue 125)

* Added ability to choose SSL version by passing an ``ssl.PROTOCOL_*`` constant
to the ``ssl_version`` parameter of ``HTTPSConnectionPool``. (Issue 109)

* Allow an explicit content type to be specified when encoding file fields.
(Issue 126)

* Exceptions are now pickleable, with tests. (Issue 101)

* Fixed default headers not getting passed in some cases. (Issue 99)

* Treat "content-encoding" header value as case-insensitive, per RFC 2616
Section 3.5. (Issue 110)

* "Connection Refused" SocketErrors will get retried rather than raised.
(Issue 92)

* Updated vendored ``six``, no longer overrides the global ``six`` module
namespace. (Issue 113)

* ``urllib3.exceptions.MaxRetryError`` contains a ``reason`` property holding
the exception that prompted the final retry. If ``reason is None`` then it
was due to a redirect. (Issue 92, 114)

* Fixed ``PoolManager.urlopen()`` from not redirecting more than once.
(Issue 149)

* Don't assume ``Content-Type: text/plain`` for multi-part encoding parameters
that are not files. (Issue 111)

* Pass `strict` param down to ``httplib.HTTPConnection``. (Issue 122)

* Added mechanism to verify SSL certificates by fingerprint (md5, sha1) or
against an arbitrary hostname (when connecting by IP or for misconfigured
servers). (Issue 140)

* Streaming decompression support. (Issue 159)```



### 1.5
```----------------

* Added ``urllib3.add_stderr_logger()`` for quickly enabling STDERR debug
logging in urllib3.

* Native full URL parsing (including auth, path, query, fragment) available in
``urllib3.util.parse_url(url)``.

* Built-in redirect will switch method to 'GET' if status code is 303.
(Issue 11)

* ``urllib3.PoolManager`` strips the scheme and host before sending the request
uri. (Issue 8)

* New ``urllib3.exceptions.DecodeError`` exception for when automatic decoding,
based on the Content-Type header, fails.

* Fixed bug with pool depletion and leaking connections (Issue 76). Added
explicit connection closing on pool eviction. Added
``urllib3.PoolManager.clear()``.

* 99% -> 100% unit test coverage.```



### 1.4
```----------------

* Minor AppEngine-related fixes.

* Switched from ``mimetools.choose_boundary`` to ``uuid.uuid4()``.

* Improved url parsing. (Issue 73)

* IPv6 url support. (Issue 72)```



### 1.3
```----------------

* Removed pre-1.0 deprecated API.

* Refactored helpers into a ``urllib3.util`` submodule.

* Fixed multipart encoding to support list-of-tuples for keys with multiple
values. (Issue 48)

* Fixed multiple Set-Cookie headers in response not getting merged properly in
Python 3. (Issue 53)

* AppEngine support with Py27. (Issue 61)

* Minor ``encode_multipart_formdata`` fixes related to Python 3 strings vs
bytes.```



### 1.2.2
```------------------

* Fixed packaging bug of not shipping ``test-requirements.txt``. (Issue 47)```



### 1.2.1
```------------------

* Fixed another bug related to when ``ssl`` module is not available. (Issue 41)

* Location parsing errors now raise ``urllib3.exceptions.LocationParseError``
which inherits from ``ValueError``.```



### 1.2
```----------------

* Added Python 3 support (tested on 3.2.2)

* Dropped Python 2.5 support (tested on 2.6.7, 2.7.2)

* Use ``select.poll`` instead of ``select.select`` for platforms that support
it.

* Use ``Queue.LifoQueue`` instead of ``Queue.Queue`` for more aggressive
connection reusing. Configurable by overriding ``ConnectionPool.QueueCls``.

* Fixed ``ImportError`` during install when ``ssl`` module is not available.
(Issue 41)

* Fixed ``PoolManager`` redirects between schemes (such as HTTP -> HTTPS) not
completing properly. (Issue 28, uncovered by Issue 10 in v1.1)

* Ported ``dummyserver`` to use ``tornado`` instead of ``webob`` +
``eventlet``. Removed extraneous unsupported dummyserver testing backends.
Added socket-level tests.

* More tests. Achievement Unlocked: 99% Coverage.```



### 1.1
```----------------

* Refactored ``dummyserver`` to its own root namespace module (used for
testing).

* Added hostname verification for ``VerifiedHTTPSConnection`` by vendoring in
Py32's ``ssl_match_hostname``. (Issue 25)

* Fixed cross-host HTTP redirects when using ``PoolManager``. (Issue 10)

* Fixed ``decode_content`` being ignored when set through ``urlopen``. (Issue
27)

* Fixed timeout-related bugs. (Issues 17, 23)```



### 1.0.2
```------------------

* Fixed typo in ``VerifiedHTTPSConnection`` which would only present as a bug if
you're using the object manually. (Thanks pyos)

* Made RecentlyUsedContainer (and consequently PoolManager) more thread-safe by
wrapping the access log in a mutex. (Thanks christer)

* Made RecentlyUsedContainer more dict-like (corrected ``__delitem__`` and
``__getitem__`` behaviour), with tests. Shouldn't affect core urllib3 code.```



### 1.0.1
```------------------

* Fixed a bug where the same connection would get returned into the pool twice,
causing extraneous "HttpConnectionPool is full" log warnings.```



### 1.0
```----------------

* Added ``PoolManager`` with LRU expiration of connections (tested and
documented).
* Added ``ProxyManager`` (needs tests, docs, and confirmation that it works
with HTTPS proxies).
* Added optional partial-read support for responses when
``preload_content=False``. You can now make requests and just read the headers
without loading the content.
* Made response decoding optional (default on, same as before).
* Added optional explicit boundary string for ``encode_multipart_formdata``.
* Convenience request methods are now inherited from ``RequestMethods``. Old
helpers like ``get_url`` and ``post_url`` should be abandoned in favour of
the new ``request(method, url, ...)``.
* Refactored code to be even more decoupled, reusable, and extendable.
* License header added to ``.py`` files.
* Embiggened the documentation: Lots of Sphinx-friendly docstrings in the code
and docs in ``docs/`` and on urllib3.readthedocs.org.
* Embettered all the things!
* Started writing this file.```



### 0.4.1
```------------------

* Minor bug fixes, code cleanup.```



### 0.4
```----------------

* Better unicode support.
* Added ``VerifiedHTTPSConnection``.
* Added ``NTLMConnectionPool`` in contrib.
* Minor improvements.```



### 0.3.1
```------------------

* Added ``assert_host_name`` optional parameter. Now compatible with proxies.```



### 0.3
```----------------

* Added HTTPS support.
