[pyup-bot]

This PR updates Werkzeug from 0.14.1 to 0.15.2.

Changelog

0.15.2

--------------

Released 2019-04-02

-   ``Rule`` code generation uses a filename that coverage will ignore.
 The previous value, "generated", was causing coverage to fail.
 (:issue:`1487`)
-   The test client removes the cookie header if there are no persisted
 cookies. This fixes an issue introduced in 0.15.0 where the cookies
 from the original request were used for redirects, causing functions
 such as logout to fail. (:issue:`1491`)
-   The test client copies the environ before passing it to the app, to
 prevent in-place modifications from affecting redirect requests.
 (:issue:`1498`)
-   The ``"werkzeug"`` logger only adds a handler if there is no handler
 configured for its level in the logging chain. This avoids double
 logging if other code configures logging first. (:issue:`1492`)

0.15.1

--------------

Released 2019-03-21

-   :class:`~exceptions.Unauthorized` takes ``description`` as the first
 argument, restoring previous behavior. The new ``www_authenticate``
 argument is listed second. (:issue:`1483`)

0.15.0

--------------

Released 2019-03-19

-   Building URLs is ~7x faster. Each :class:`~routing.Rule` compiles
 an optimized function for building itself. (:pr:`1281`)
-   :meth:`MapAdapter.build() <routing.MapAdapter.build>` can be passed
 a :class:`~datastructures.MultiDict` to represent multiple values
 for a key. It already did this when passing a dict with a list
 value. (:pr:`724`)
-   ``path_info`` defaults to ``'/'`` for
 :meth:`Map.bind() <routing.Map.bind>`. (:issue:`740`, :pr:`768`,
 :pr:`1316`)
-   Change ``RequestRedirect`` code from 301 to 308, preserving the verb
 and request body (form data) during redirect. (:pr:`1342`)
-   ``int`` and ``float`` converters in URL rules will handle negative
 values if passed the ``signed=True`` parameter. For example,
 ``/jump/<int(signed=True):count>``. (:pr:`1355`)
-   ``Location`` autocorrection in :func:`Response.get_wsgi_headers()
 <wrappers.BaseResponse.get_wsgi_headers>` is relative to the current
 path rather than the root path. (:issue:`693`, :pr:`718`,
 :pr:`1315`)
-   412 responses once again include entity headers and an error message
 in the body. They were originally omitted when implementing
 ``If-Match`` (:pr:`1233`), but the spec doesn't seem to disallow it.
 (:issue:`1231`, :pr:`1255`)
-   The Content-Length header is removed for 1xx and 204 responses. This
 fixes a previous change where no body would be sent, but the header
 would still be present. The new behavior matches RFC 7230.
 (:pr:`1294`)
-   :class:`~exceptions.Unauthorized` takes a ``www_authenticate``
 parameter to set the ``WWW-Authenticate`` header for the response,
 which is technically required for a valid 401 response.
 (:issue:`772`, :pr:`795`)
-   Add support for status code 424 :exc:`~exceptions.FailedDependency`.
 (:pr:`1358`)
-   :func:`http.parse_cookie` ignores empty segments rather than
 producing a cookie with no key or value. (:issue:`1245`, :pr:`1301`)
-   :func:`~http.parse_authorization_header` (and
 :class:`~datastructures.Authorization`,
 :attr:`~wrappers.Request.authorization`) treats the authorization
 header as UTF-8. On Python 2, basic auth username and password are
 ``unicode``. (:pr:`1325`)
-   :func:`~http.parse_options_header` understands :rfc:`2231` parameter
 continuations. (:pr:`1417`)
-   :func:`~urls.uri_to_iri` does not unquote ASCII characters in the
 unreserved class, such as space, and leaves invalid bytes quoted
 when decoding. :func:`~urls.iri_to_uri` does not quote reserved
 characters. See :rfc:`3987` for these character classes.
 (:pr:`1433`)
-   ``get_content_type`` appends a charset for any mimetype that ends
 with ``+xml``, not just those that start with ``application/``.
 Known text types such as ``application/javascript`` are also given
 charsets. (:pr:`1439`)
-   Clean up ``werkzeug.security`` module, remove outdated hashlib
 support. (:pr:`1282`)
-   In :func:`~security.generate_password_hash`, PBKDF2 uses 150000
 iterations by default, increased from 50000. (:pr:`1377`)
-   :class:`~wsgi.ClosingIterator` calls ``close`` on the wrapped
 *iterable*, not the internal iterator. This doesn't affect objects
 where ``__iter__`` returned ``self``. For other objects, the method
 was not called before. (:issue:`1259`, :pr:`1260`)
-   Bytes may be used as keys in :class:`~datastructures.Headers`, they
 will be decoded as Latin-1 like values are. (:pr:`1346`)
-   :class:`~datastructures.Range` validates that list of range tuples
 passed to it would produce a valid ``Range`` header. (:pr:`1412`)
-   :class:`~datastructures.FileStorage` looks up attributes on
 ``stream._file`` if they don't exist on ``stream``, working around
 an issue where :func:`tempfile.SpooledTemporaryFile` didn't
 implement all of :class:`io.IOBase`. See
 https://github.com/python/cpython/pull/3249. (:pr:`1409`)
-   :class:`CombinedMultiDict.copy() <datastructures.CombinedMultiDict>`
 returns a shallow mutable copy as a
 :class:`~datastructures.MultiDict`. The copy no longer reflects
 changes to the combined dicts, but is more generally useful.
 (:pr:`1420`)
-   The version of jQuery used by the debugger is updated to 3.3.1.
 (:pr:`1390`)
-   The debugger correctly renders long ``markupsafe.Markup`` instances.
 (:pr:`1393`)
-   The debugger can serve resources when Werkzeug is installed as a
 zip file. ``DebuggedApplication.get_resource`` uses
 ``pkgutil.get_data``. (:pr:`1401`)
-   The debugger and server log support Python 3's chained exceptions.
 (:pr:`1396`)
-   The interactive debugger highlights frames that come from user code
 to make them easy to pick out in a long stack trace. Note that if an
 env was created with virtualenv instead of venv, the debugger may
 incorrectly classify some frames. (:pr:`1421`)
-   Clicking the error message at the top of the interactive debugger
 will jump down to the bottom of the traceback. (:pr:`1422`)
-   When generating a PIN, the debugger will ignore a ``KeyError``
 raised when the current UID doesn't have an associated username,
 which can happen in Docker. (:issue:`1471`)
-   :class:`~exceptions.BadRequestKeyError` adds the ``KeyError``
 message to the description, making it clearer what caused the 400
 error. Frameworks like Flask can omit this information in production
 by setting ``e.args = ()``. (:pr:`1395`)
-   If a nested ``ImportError`` occurs from :func:`~utils.import_string`
 the traceback mentions the nested import. Removes an untested code
 path for handling "modules not yet set up by the parent."
 (:pr:`735`)
-   Triggering a reload while using a tool such as PDB no longer hides
 input. (:pr:`1318`)
-   The reloader will not prepend the Python executable to the command
 line if the Python file is marked executable. This allows the
 reloader to work on NixOS. (:pr:`1242`)
-   Fix an issue where ``sys.path`` would change between reloads when
 running with ``python -m app``. The reloader can detect that a
 module was run with "-m" and reconstructs that instead of the file
 path in ``sys.argv`` when reloading. (:pr:`1416`)
-   The dev server can bind to a Unix socket by passing a hostname like
 ``unix://app.socket``. (:pr:`209`, :pr:`1019`)
-   Server uses ``IPPROTO_TCP`` constant instead of ``SOL_TCP`` for
 Jython compatibility. (:pr:`1375`)
-   When using an adhoc SSL cert with :func:`~serving.run_simple`, the
 cert is shown as self-signed rather than signed by an invalid
 authority. (:pr:`1430`)
-   The development server logs the unquoted IRI rather than the raw
 request line, to make it easier to work with Unicode in request
 paths during development. (:issue:`1115`)
-   The development server recognizes ``ConnectionError`` on Python 3 to
 silence client disconnects, and does not silence other ``OSErrors``
 that may have been raised inside the application. (:pr:`1418`)
-   The environ keys ``REQUEST_URI`` and ``RAW_URI`` contain the raw
 path before it was percent-decoded. This is non-standard, but many
 WSGI servers add them. Middleware could replace ``PATH_INFO`` with
 this to route based on the raw value. (:pr:`1419`)
-   :class:`~test.EnvironBuilder` doesn't set ``CONTENT_TYPE`` or
 ``CONTENT_LENGTH`` in the environ if they aren't set. Previously
 these used default values if they weren't set. Now it's possible to
 distinguish between empty and unset values. (:pr:`1308`)
-   The test client raises a ``ValueError`` if a query string argument
 would overwrite a query string in the path. (:pr:`1338`)
-   :class:`test.EnvironBuilder` and :class:`test.Client` take a
 ``json`` argument instead of manually passing ``data`` and
 ``content_type``. This is serialized using the
 :meth:`test.EnvironBuilder.json_dumps` method. (:pr:`1404`)
-   :class:`test.Client` redirect handling is rewritten. (:pr:`1402`)

 -   The redirect environ is copied from the initial request environ.
 -   Script root and path are correctly distinguished when
     redirecting to a path under the root.
 -   The HEAD method is not changed to GET.
 -   307 and 308 codes preserve the method and body. All others
     ignore the body and related headers.
 -   Headers are passed to the new request for all codes, following
     what browsers do.
 -   :class:`test.EnvironBuilder` sets the content type and length
     headers in addition to the WSGI keys when detecting them from
     the data.
 -   Intermediate response bodies are iterated over even when
     ``buffered=False`` to ensure iterator middleware can run cleanup
     code safely. Only the last response is not buffered. (:pr:`988`)

-   :class:`~test.EnvironBuilder`, :class:`~datastructures.FileStorage`,
 and :func:`wsgi.get_input_stream` no longer share a global
 ``_empty_stream`` instance. This improves test isolation by
 preventing cases where closing the stream in one request would
 affect other usages. (:pr:`1340`)
-   The default ``SecureCookie.serialization_method`` will change from
 :mod:`pickle` to :mod:`json` in 1.0. To upgrade existing tokens,
 override :meth:`~contrib.securecookie.SecureCookie.unquote` to try
 ``pickle`` if ``json`` fails. (:pr:`1413`)
-   ``CGIRootFix`` no longer modifies ``PATH_INFO`` for very old
 versions of Lighttpd. ``LighttpdCGIRootFix`` was renamed to
 ``CGIRootFix`` in 0.9. Both are deprecated and will be removed in
 version 1.0. (:pr:`1141`)
-   :class:`werkzeug.wrappers.json.JSONMixin` has been replaced with
 Flask's implementation. Check the docs for the full API.
 (:pr:`1445`)
-   The contrib modules are deprecated and will either be moved into
 ``werkzeug`` core or removed completely in version 1.0. Some modules
 that already issued deprecation warnings have been removed. Be sure
 to run or test your code with
 ``python -W default::DeprecationWarning`` to catch any deprecated
 code you're using. (:issue:`4`)

 -   ``LintMiddleware`` has moved to :mod:`werkzeug.middleware.lint`.
 -   ``ProfilerMiddleware`` has moved to
     :mod:`werkzeug.middleware.profiler`.
 -   ``ProxyFix`` has moved to :mod:`werkzeug.middleware.proxy_fix`.
 -   ``JSONRequestMixin`` has moved to :mod:`werkzeug.wrappers.json`.
 -   ``cache`` has been extracted into a separate project,
     `cachelib <https://github.com/pallets/cachelib>`_. The version
     in Werkzeug is deprecated.
 -   ``securecookie`` and ``sessions`` have been extracted into a
     separate project,
     `secure-cookie <https://github.com/pallets/secure-cookie>`_. The
     version in Werkzeug is deprecated.
 -   Everything in ``fixers``, except ``ProxyFix``, is deprecated.
 -   Everything in ``wrappers``, except ``JSONMixin``, is deprecated.
 -   ``atom`` is deprecated. This did not fit in with the rest of
     Werkzeug, and is better served by a dedicated library in the
     community.
 -   ``jsrouting`` is removed. Set URLs when rendering templates
     or JSON responses instead.
 -   ``limiter`` is removed. Its specific use is handled by Werkzeug
     directly, but stream limiting is better handled by the WSGI
     server in general.
 -   ``testtools`` is removed. It did not offer significant benefit
     over the default test client.
 -   ``iterio`` is deprecated.

-   :func:`wsgi.get_host` no longer looks at ``X-Forwarded-For``. Use
 :class:`~middleware.proxy_fix.ProxyFix` to handle that.
 (:issue:`609`, :pr:`1303`)
-   :class:`~middleware.proxy_fix.ProxyFix` is refactored to support
 more headers, multiple values, and more secure configuration.

 -   Each header supports multiple values. The trusted number of
     proxies is configured separately for each header. The
     ``num_proxies`` argument is deprecated. (:pr:`1314`)
 -   Sets ``SERVER_NAME`` and ``SERVER_PORT`` based on
     ``X-Forwarded-Host``. (:pr:`1314`)
 -   Sets ``SERVER_PORT`` and modifies ``HTTP_HOST`` based on
     ``X-Forwarded-Port``. (:issue:`1023`, :pr:`1304`)
 -   Sets ``SCRIPT_NAME`` based on ``X-Forwarded-Prefix``.
     (:issue:`1237`)
 -   The original WSGI environment values are stored in the
     ``werkzeug.proxy_fix.orig`` key, a dict. The individual keys
     ``werkzeug.proxy_fix.orig_remote_addr``,
     ``werkzeug.proxy_fix.orig_wsgi_url_scheme``, and
     ``werkzeug.proxy_fix.orig_http_host`` are deprecated.

-   Middleware from ``werkzeug.wsgi`` has moved to separate modules
 under ``werkzeug.middleware``, along with the middleware moved from
 ``werkzeug.contrib``. The old ``werkzeug.wsgi`` imports are
 deprecated and will be removed in version 1.0. (:pr:`1452`)

 -   ``werkzeug.wsgi.DispatcherMiddleware`` has moved to
     :class:`werkzeug.middleware.dispatcher.DispatcherMiddleware`.
 -   ``werkzeug.wsgi.ProxyMiddleware`` as moved to
     :class:`werkzeug.middleware.http_proxy.ProxyMiddleware`.
 -   ``werkzeug.wsgi.SharedDataMiddleware`` has moved to
     :class:`werkzeug.middleware.shared_data.SharedDataMiddleware`.

-   :class:`~middleware.http_proxy.ProxyMiddleware` proxies the query
 string. (:pr:`1252`)
-   The filenames generated by
 :class:`~middleware.profiler.ProfilerMiddleware` can be customized.
 (:issue:`1283`)
-   The ``werkzeug.wrappers`` module has been converted to a package,
 and its various classes have been organized into separate modules.
 Any previously documented classes, understood to be the existing
 public API, are still importable from ``werkzeug.wrappers``, or may
 be imported from their specific modules. (:pr:`1456`)
