GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!

.. note::
Our ISO-8859-2 and windows-1250 (Hungarian) probers have been temporarily
disabled until we can retrain the models.
Requires Python 2.7 or 3.5+.
Installation
------------
Install from `PyPI <https://pypi.org/project/chardet/>`_::
pip install chardet
Documentation
-------------
For users, docs are now available at https://chardet.readthedocs.io/.
Command-line Tool
-----------------
chardet comes with a command-line script which reports on the encodings of one
or more files::
% chardetect somefile someotherfile
somefile: windows-1252 with confidence 0.5
someotherfile: ascii with confidence 1.0
About
-----
This is a continuation of Mark Pilgrim's excellent chardet. Previously, two
versions needed to be maintained: one that supported python 2.x and one that
supported python 3.x. We've recently merged with `Ian Cordasco <https://github.com/sigmavirus24>`_'s
`charade <https://github.com/sigmavirus24/charade>`_ fork, so now we have one
coherent version that works for Python 2.7+ and 3.4+.

# Requests
**Requests** is a simple, yet elegant HTTP library.
```python
>>> import requests
>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
'{"type":"User"...'
>>> r.json()
{'disk_usage': 368627, 'private_gists': 484, ...}
```
Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method!
Requests is one of the most downloaded Python package today, pulling in around `14M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `500,000+` repositories. You may certainly put your trust in this code.

urllib3 is a powerful, *user-friendly* HTTP client for Python. Much of the
Python ecosystem already uses urllib3 and you should too.
urllib3 brings many critical features that are missing from the Python
standard libraries:
- Thread safety.
- Connection pooling.
- Client-side SSL/TLS verification.
- File uploads with multipart encoding.
- Helpers for retrying requests and dealing with HTTP redirects.
- Support for gzip, deflate, and brotli encoding.
- Proxy support for HTTP and SOCKS.
- 100% test coverage.
urllib3 is powerful and easy to use:
.. code-block:: python
>>> import urllib3
>>> http = urllib3.PoolManager()
>>> r = http.request('GET', 'http://httpbin.org/robots.txt')
>>> r.status
200
>>> r.data
'User-agent: *\nDisallow: /deny\n'
Installing
----------

Changes
=======
1.26.3 (2021-01-26)
-------------------
* Fixed bytes and string comparison issue with headers (Pull #2141)
* Changed ``ProxySchemeUnknown`` error message to be
more actionable if the user supplies a proxy URL without
a scheme. (Pull #2107)
1.26.2 (2020-11-12)
-------------------
* Fixed an issue where ``wrap_socket`` and ``CERT_REQUIRED`` wouldn't
be imported properly on Python 2.7.8 and earlier (Pull #2052)
1.26.1 (2020-11-11)
-------------------
* Fixed an issue where two ``User-Agent`` headers would be sent if a
``User-Agent`` header key is passed as ``bytes`` (Pull #2047)
1.26.0 (2020-11-10)
-------------------
* **NOTE: urllib3 v2.0 will drop support for Python 2**.
`Read more in the v2.0 Roadmap <https://urllib3.readthedocs.io/en/latest/v2-roadmap.html>`_.
* Added support for HTTPS proxies contacting HTTPS servers (Pull #1923, Pull #1806)
* Deprecated negotiating TLSv1 and TLSv1.1 by default. Users that
still wish to use TLS earlier than 1.2 without a deprecation warning
should opt-in explicitly by setting ``ssl_version=ssl.PROTOCOL_TLSv1_1`` (Pull #2002)
**Starting in urllib3 v2.0: Connections that receive a ``DeprecationWarning`` will fail**
* Deprecated ``Retry`` options ``Retry.DEFAULT_METHOD_WHITELIST``, ``Retry.DEFAULT_REDIRECT_HEADERS_BLACKLIST``
and ``Retry(method_whitelist=...)`` in favor of ``Retry.DEFAULT_ALLOWED_METHODS``,
``Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT``, and ``Retry(allowed_methods=...)``
(Pull #2000) **Starting in urllib3 v2.0: Deprecated options will be removed**
* Added default ``User-Agent`` header to every request (Pull #1750)
* Added ``urllib3.util.SKIP_HEADER`` for skipping ``User-Agent``, ``Accept-Encoding``,
and ``Host`` headers from being automatically emitted with requests (Pull #2018)
* Collapse ``transfer-encoding: chunked`` request data and framing into
the same ``socket.send()`` call (Pull #1906)
* Send ``http/1.1`` ALPN identifier with every TLS handshake by default (Pull #1894)
* Properly terminate SecureTransport connections when CA verification fails (Pull #1977)
* Don't emit an ``SNIMissingWarning`` when passing ``server_hostname=None``
to SecureTransport (Pull #1903)
* Disabled requesting TLSv1.2 session tickets as they weren't being used by urllib3 (Pull #1970)
* Suppress ``BrokenPipeError`` when writing request body after the server
has closed the socket (Pull #1524)

into an ``urllib3.exceptions.SSLError`` (Pull #1939)
1.25.11 (2020-10-19)
--------------------
* Fix retry backoff time parsed from ``Retry-After`` header when given
in the HTTP date format. The HTTP date was parsed as the local timezone
rather than accounting for the timezone in the HTTP date (typically
UTC) (Pull #1932, Pull #1935, Pull #1938, Pull #1949)
* Fix issue where an error would be raised when the ``SSLKEYLOGFILE``
environment variable was set to the empty string. Now ``SSLContext.keylog_file``
is not set in this situation (Pull #2016)
1.25.10 (2020-07-22)
--------------------
* Added support for ``SSLKEYLOGFILE`` environment variable for
logging TLS session keys with use with programs like
Wireshark for decrypting captured web traffic (Pull #1867)
* Fixed loading of SecureTransport libraries on macOS Big Sur
due to the new dynamic linker cache (Pull #1905)
* Collapse chunked request bodies data and framing into one
call to ``send()`` to reduce the number of TCP packets by 2-4x (Pull #1906)
* Don't insert ``None`` into ``ConnectionPool`` if the pool
was empty when requesting a connection (Pull #1866)
* Avoid ``hasattr`` call in ``BrotliDecoder.decompress()`` (Pull #1858)
1.25.9 (2020-04-16)
-------------------
* Added ``InvalidProxyConfigurationWarning`` which is raised when
erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently
support connecting to HTTPS proxies but will soon be able to
and we would like users to migrate properly without much breakage.
See `this GitHub issue <https://github.com/urllib3/urllib3/issues/1850>`_
for more information on how to fix your proxy config. (Pull #1851)
* Drain connection after ``PoolManager`` redirect (Pull #1817)
* Ensure ``load_verify_locations`` raises ``SSLError`` for all backends (Pull #1812)
* Rename ``VerifiedHTTPSConnection`` to ``HTTPSConnection`` (Pull #1805)
* Allow the CA certificate data to be passed as a string (Pull #1804)
* Raise ``ValueError`` if method contains control characters (Pull #1800)
* Add ``__repr__`` to ``Timeout`` (Pull #1795)

1.25.6 (2019-09-24)
-------------------
* Fix issue where tilde (``~``) characters were incorrectly
percent-encoded in the path. (Pull #1692)
1.25.5 (2019-09-19)
-------------------
* Add mitigation for BPO-37428 affecting Python <3.7.4 and OpenSSL 1.1.1+ which
caused certificate verification to be enabled when using ``cert_reqs=CERT_NONE``.
(Issue #1682)
1.25.4 (2019-09-19)
-------------------
* Propagate Retry-After header settings to subsequent retries. (Pull #1607)
* Fix edge case where Retry-After header was still respected even when
explicitly opted out of. (Pull #1607)
* Remove dependency on ``rfc3986`` for URL parsing.
* Fix issue where URLs containing invalid characters within ``Url.auth`` would
raise an exception instead of percent-encoding those characters.
* Add support for ``HTTPResponse.auto_close = False`` which makes HTTP responses
work well with BufferedReaders and other ``io`` module features. (Pull #1652)
* Percent-encode invalid characters in URL for ``HTTPConnectionPool.request()`` (Pull #1673)
1.25.3 (2019-05-23)

implementations. (Pull #1496)
* Switched the default multipart header encoder from RFC 2231 to HTML 5 working draft. (Issue #303, Pull #1492)
* Fixed issue where OpenSSL would block if an encrypted client private key was
given and no password was given. Instead an ``SSLError`` is raised. (Pull #1489)
* Added support for Brotli content encoding. It is enabled automatically if
``brotlipy`` package is installed which can be requested with
``urllib3[brotli]`` extra. (Pull #1532)

* Move urllib3 to src/urllib3 (Pull #1409)
1.23 (2018-06-04)
-----------------
* Allow providing a list of headers to strip from requests when redirecting
to a different host. Defaults to the ``Authorization`` header. Different
headers can be set via ``Retry.remove_headers_on_redirect``. (Issue #1316)
* Fix ``util.selectors._fileobj_to_fd`` to accept ``long`` (Issue #1247).

attempted to auth via certificate + chain (Issue #1060)
* Add the port to the connectionpool connect print (Pull #1251)
* Don't use the ``uuid`` module to create multipart data boundaries. (Pull #1380)

-----------------
* 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)

``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 (2017-01-19)
-----------------
* Added support for waiting for I/O using selectors other than select,
improving urllib3's behaviour with large numbers of concurrent connections.

retried or redirected. (Pull #1039)
* Fix some bugs that occur when modules incautiously patch the queue module.
(Pull #1061)

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 (2016-11-16)
-------------------
* Fixed AppEngine import that didn't function on Python 3.5. (Pull #1025)
1.19 (2016-11-03)
-----------------
* 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 suppressed. (Issue #1015)
* Prefer user-supplied Host headers on chunked uploads. (Issue #1009)
1.18.1 (2016-10-27)
-------------------
* 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 Pull #1010.
1.18 (2016-09-26)
-----------------
* Fixed incorrect message for IncompleteRead exception. (Pull #973)

-----------------
* Accept ``SSLContext`` objects for use in SSL/TLS negotiation. (Issue #835)
* ConnectionPool debug log now includes scheme, host, and port. (Issue #897)
* Substantially refactored documentation. (Issue #887)
* 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.
(Pull #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. (Pull #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``. (Pull #941)
* Updated cipher suite list to allow ChaCha20+Poly1305. AES-GCM is preferred to
ChaCha20, but ChaCha20 is then preferred to everything else. (Pull #947)
* Updated cipher suite list to remove 3DES-based cipher suites. (Pull #958)
* Removed the cipher suite fallback to allow HIGH ciphers. (Pull #958)
* Implemented ``length_remaining`` to determine remaining content
to be read. (Pull #949)
* Implemented ``enforce_content_length`` to enable exceptions when
incomplete data chunks are received. (Pull #949)
* Dropped connection start, dropped connection reset, redirect, forced retry,
and new HTTPS connection log levels to DEBUG, from INFO. (Pull #967)
1.16 (2016-06-11)
-----------------
* Disable IPv6 DNS when IPv6 connections are not possible. (Issue #840)
* Provide ``key_fn_by_scheme`` pool keying mechanism that can be

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 (2016-04-11)
-------------------
* Fix packaging to include backports module. (Issue #841)

repeatedly flushing the decoder, to function better on Jython. (Issue #743)
* Accept ``ca_cert_dir`` for SSL-related PoolManager configuration. (Issue #758)
1.12 (2015-09-03)
-----------------
* Rely on ``six`` for importing ``httplib`` to work around
conflicts with other Python 3 shims. (Issue #688)
* Add support for directories of certificate authorities, as supported by
OpenSSL. (Issue #701)

* Dev: Added test suite for AppEngine. (Issue #631)
* Fix performance regression when using PyOpenSSL. (Issue #626)

* Fixed PyOpenSSL + gevent ``WantWriteError``. (Issue #412)
* ``MaxRetryError.reason`` will always be an exception, not string.
(Issue #481)
* Fixed SSL-related timeouts not being detected as timeouts. (Issue #492)

1.9 (2014-07-04)
----------------
* 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)
* New retry logic and ``urllib3.util.retry.Retry`` configuration object.
(Issue #326)
* All raised exceptions should now wrapped in a
``urllib3.exceptions.HTTPException``-extending exception. (Issue #326)
* All errors during a retry-enabled request should be wrapped in
``urllib3.exceptions.MaxRetryError``, including timeout-related exceptions
which were previously exempt. Underlying error is accessible from the
``.reason`` property. (Issue #326)
* ``urllib3.exceptions.ConnectionError`` renamed to
``urllib3.exceptions.ProtocolError``. (Issue #326)
* Errors during response read (such as IncompleteRead) are now wrapped in
``urllib3.exceptions.ProtocolError``. (Issue #418)

``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 (2014-04-17)
------------------
* Fix ``urllib3.util`` not being included in the package.
1.8.1 (2014-04-17)
------------------
* 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 (2014-03-04)
----------------
* 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)
* Requests with ``retries=False`` will immediately raise any exceptions without
wrapping them in ``MaxRetryError``. (Issue #348)
* Fixed open socket leak with SSL-related failures. (Issue #344, #348)
1.7.1 (2013-09-25)
------------------
* Added granular timeout support with new ``urllib3.util.Timeout`` class.
(Issue #231)
* Fixed Python 3.4 support. (Issue #238)
1.7 (2013-08-14)
----------------
* 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)
* Added HTTPS proxy support in ``ProxyManager``. (Issue #170 #139)
* New ``RequestField`` object can be passed to the ``fields=...`` param which
can specify headers. (Issue #220)
* Raise ``urllib3.exceptions.ProxyError`` when connecting to proxy fails.
(Issue #221)
* Use international headers when posting file names. (Issue #119)
* Improved IPv6 support. (Issue #203)
1.6 (2013-04-25)
----------------
* 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 (2012-08-02)
----------------
* 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 (2012-06-16)
----------------
* Minor AppEngine-related fixes.
* Switched from ``mimetools.choose_boundary`` to ``uuid.uuid4()``.
* Improved url parsing. (Issue #73)
* IPv6 url support. (Issue #72)
1.3 (2012-03-25)
----------------
* 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 (2012-02-06)
------------------
* Fixed packaging bug of not shipping ``test-requirements.txt``. (Issue #47)
1.2.1 (2012-02-05)
------------------
* 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 (2012-01-29)
----------------
* 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 (2012-01-07)
----------------
* 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 (2011-11-04)
------------------
* 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 (2011-10-10)
------------------
* Fixed a bug where the same connection would get returned into the pool twice,
causing extraneous "HttpConnectionPool is full" log warnings.
1.0 (2011-10-08)
----------------
* 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 https://urllib3.readthedocs.io/.
* Embettered all the things!
* Started writing this file.
0.4.1 (2011-07-17)
------------------
* Minor bug fixes, code cleanup.
0.4 (2011-03-01)
----------------
* Better unicode support.
* Added ``VerifiedHTTPSConnection``.
* Added ``NTLMConnectionPool`` in contrib.
* Minor improvements.
0.3.1 (2010-07-13)
------------------
* Added ``assert_host_name`` optional parameter. Now compatible with proxies.
0.3 (2009-12-10)
----------------
* Added HTTPS support.
* Minor bug fixes.
* Refactored, broken backwards compatibility with 0.2.
* API to be treated as stable from this version forward.
0.2 (2008-11-17)
----------------
* Added unit tests.
* Bug fixes.
0.1 (2008-11-16)
----------------
* First release.

*not* do certificate checking; you need to do additional work to validate
certificates yourself.
This needs the following packages installed:

* `cryptography`_ (minimum 1.3.4, from pyopenssl)
* `idna`_ (minimum 2.0, from cryptography)
* 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:
.. code-block:: bash
$ python -m pip install pyopenssl cryptography idna
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``,
