1.8.0 (2018-04-04)
------------------
Feature
~~~~~~~
- ``request.POST`` now supports any requests with the appropriate
Content-Type. Allowing any HTTP method to access form encoded content,
including DELETE, PUT, and others. See
https://github.com/Pylons/webob/pull/352
Compatibility
~~~~~~~~~~~~~
- WebOb is no longer officially supported on Python 3.3 which was EOL'ed on
2017-09-29.
Backwards Incompatibilities
~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Many changes have been made to the way WebOb does Accept handling, not just
for the Accept header itself, but also for Accept-Charset, Accept-Encoding
and Accept-Language. This was a `Google Summer of Code
<https://developers.google.com/open-source/gsoc/>`_ project completed by
Whiteroses (https://github.com/whiteroses). Many thanks to Google for running
GSoC, the Python Software Foundation for organising and a huge thanks to Ira
for completing the work. See https://github.com/Pylons/webob/pull/338 and
https://github.com/Pylons/webob/pull/335. Documentation is available at
https://docs.pylonsproject.org/projects/webob/en/master/api/webob.html
- When calling a ``@wsgify`` decorated function, the default arguments passed
to ``@wsgify`` are now used when called with the request, and not as a
`start_response`
.. code::
def hello(req, name):
return "Hello, %s!" % name
app = wsgify(hello, args=("Fred",))
req = Request.blank('/')
resp = req.get_response(app) # => "Hello, Fred"
resp2 = app(req) # => "Hello, Fred"
Previously the ``resp2`` line would have failed with a ``TypeError``. With
this change there is no way to override the default arguments with no
arguments. See https://github.com/Pylons/webob/pull/203
- When setting ``app_iter`` on a ``Response`` object the ``content_md5`` header
is no longer cleared. This behaviour is odd and disallows setting the
``content_md5`` and then returning an iterator for chunked content encoded
responses. See https://github.com/Pylons/webob/issues/86
Experimental Features
~~~~~~~~~~~~~~~~~~~~~
These features are experimental and may change at any point in the future.
- The cookie APIs now have the ability to set the SameSite attribute on a
cookie in both ``webob.cookies.make_cookie`` and
``webob.cookies.CookieProfile``. See https://github.com/Pylons/webob/pull/255
Bugfix
~~~~~~
- Exceptions now use string.Template.safe_substitute rather than
string.Template.substitute. The latter would raise for missing mappings, the
former will simply not substitute the missing variable. This is safer in case
the WSGI environ does not contain the keys necessary for the body template.
See https://github.com/Pylons/webob/issues/345.
- Request.host_url, Request.host_port, Request.domain correctly parse IPv6 Host
headers as provided by a browser. See
https://github.com/Pylons/webob/pull/332
- Request.authorization would raise ValueError for unusual or malformed header
values. See https://github.com/Pylons/webob/issues/231
- Allow unnamed fields in form data to be properly transcoded when calling
request.decode with an alternate encoding. See
https://github.com/Pylons/webob/pull/309
- ``Response.__init__`` would discard ``app_iter`` when a ``Response`` had no
body, this would cause issues when ``app_iter`` was an object that was tied
to the life-cycle of a web application and had to be properly closed.
``app_iter`` is more advanced API for ``Response`` and thus even if it
contains a body and is thus against the HTTP RFC's, we should let the users
shoot themselves by returning a body. See
https://github.com/Pylons/webob/issues/305
1.7rc1 (2016-11-18)
-------------------
Compatibility
~~~~~~~~~~~~~
- WebOb is no longer supported on Python 2.6 and PyPy3 (due to pip no longer
supporting Python 3.2 even on PyPy)
Backwards Incompatibility
~~~~~~~~~~~~~~~~~~~~~~~~~
- ``Response.set_cookie`` no longer accepts a key argument. This was deprecated
in WebOb 1.5 and as mentioned in the deprecation, is being removed in 1.7
- ``Response.__init__`` will no longer set the default Content-Type, nor
Content-Length on Responses that don't have a body. This allows WebOb to
return proper responses for things like `Response(status='204 No Content')`.
- ``Response.text`` will no longer raise if the Content-Type does not have a
charset, it will fall back to using the new ``default_body_encoding`. To get
the old behaviour back please sub-class ``Response`` and set
``default_body_encoding`` to ``None``. See
https://github.com/Pylons/webob/pull/287
- WebOb no longer supports Chunked Encoding, this means that if you are using
WebOb and need Chunked Encoding you will be required to have a proxy that
unchunks the request for you. Please read
https://github.com/Pylons/webob/issues/279 for more background.
Feature
~~~~~~~
- ``Response`` has a new ``default_body_encoding`` which may be used to allow
getting/setting ``Response.text`` when a Content-Type has no charset. See
https://github.com/Pylons/webob/pull/287
- ``webob.Request`` with any HTTP method is now allowed to have a body. This
allows DELETE to have a request body for passing extra information. See
https://github.com/Pylons/webob/pull/283 and
https://github.com/Pylons/webob/pull/274
- Add ``tell()`` to ``ResponseBodyFile`` so that it may be used for example for
zipfile support. See https://github.com/Pylons/webob/pull/117
- Allow the return from ``wsgify.middleware`` to be used as a decorator. See
https://github.com/Pylons/webob/pull/228
Bugfix
~~~~~~
- Fixup ``cgi.FieldStorage`` on Python 3.x to work-around issue reported in
Python bug report 27777 and 24764. This is currently applied for Python
versions less than 3.7. See https://github.com/Pylons/webob/pull/294
- ``Response.set_cookie`` now accepts ``datetime`` objects for the ``expires``
kwarg and will correctly convert them to UTC with no tzinfo for use in
calculating the ``max_age``. See https://github.com/Pylons/webob/issues/254
and https://github.com/Pylons/webob/pull/292
- Fixes ``request.PATH_SAFE`` to contain all of the path safe characters
according to RFC3986. See https://github.com/Pylons/webob/pull/291
- WebOb's exceptions will lazily read underlying variables when inserted into
templates to avoid expensive computations/crashes when inserting into the
template. This had a bad performance regression on Py27 because of the way
the lazified class was created and returned. See
https://github.com/Pylons/webob/pull/284
- ``wsgify.__call__`` raised a ``TypeError`` with an unhelpful message, it will
now return the ``repr`` for the wrapped function:
https://github.com/Pylons/webob/issues/119
- ``Response.content_type`` removes the charset content-type parameter unless
the new content-type is a text like type that has a charset parameter. See
https://github.com/Pylons/webob/pull/261 and
https://github.com/Pylons/webob/issues/130
- ``Response.json``'s ``json.dumps``/``json.loads`` are now always UTF-8. It no
longer tries to use the charset.
- The ``Response.__init__`` will by default no longer set the Content-Type to
the default if a ``headerlist`` is provided. This fixes issues whereby
``Request.get_response()`` would return a Response that didn't match the
actual response. See https://github.com/Pylons/webob/pull/261 and
https://github.com/Pylons/webob/issues/205
- Cleans up the remainder of the issues with the updated WebOb exceptions that
were taught to return JSON in version 1.6. See
https://github.com/Pylons/webob/issues/237 and
https://github.com/Pylons/webob/issues/236
- ``Response.from_file`` now parses the status line correctly when the status
line contains an HTTP with version, as well as a status text that contains
multiple white spaces (e.g HTTP/1.1 404 Not Found). See
https://github.com/Pylons/webob/issues/250
- ``Response`` now has a new property named ``has_body`` that may be used to
interrogate the ``Response`` to find out if ``Response.body`` is or isn't
set.
This is used in the exception handling code so that if you use a WebOb HTTP
Exception and pass a generator to ``app_iter`` WebOb won't attempt to read
the whole thing and instead allows it to be returned to the WSGI server. See
https://github.com/Pylons/webob/pull/259
1.6.0 (2016-03-15)
------------------
Compatibility
~~~~~~~~~~~~~
- Python 3.2 is no longer supported by WebOb
Bugfix
~~~~~~
- Request.decode attempted to read from the an already consumed stream, it has
now been redirected to another stream to read from. See
https://github.com/Pylons/webob/pull/183
- The application/json media type does not allow for a charset as discovery of
the encoding is done at the JSON layer. Upon initialization of a Response
WebOb will no longer add a charset if the content-type is set to JSON. See
https://github.com/Pylons/webob/pull/197 and
https://github.com/Pylons/pyramid/issues/1611
Features
~~~~~~~~
- Lazily HTML escapes environment keys in HTTP Exceptions so that those keys in
the environ that are not used in the output of the page don't raise an
exception due to inability to be properly escaped. See
https://github.com/Pylons/webob/pull/139
- MIMEAccept now accepts comparisons against wildcards, this allows one to
match on just the media type or sub-type, without having to explicitly match
on both the media type and sub-type at the same time. See
https://github.com/Pylons/webob/pull/185
- Add the ability to return a JSON body from an exception. Using the Accept
information in the request, the exceptions will now automatically return a
JSON version of the exception instead of just HTML or text. See
https://github.com/Pylons/webob/pull/230 and
https://github.com/Pylons/webob/issues/209
Security
~~~~~~~~
- exc._HTTPMove and any subclasses will now raise a ValueError if the location
field contains a line feed or carriage return. These values may lead to
possible HTTP Response Splitting. The header_getter descriptor has also been
modified to no longer accept headers with a line feed or carriage return.
See: https://github.com/Pylons/webob/pull/229 and
https://github.com/Pylons/webob/issues/217
1.5.1 (2015-10-30)
------------------
Bug Fixes
~~~~~~~~~
- The exceptions HTTPNotAcceptable, HTTPUnsupportedMediaType and
HTTPNotImplemented will now correctly use the sub-classed template rather
than the default error template. See https://github.com/Pylons/webob/issues/221
- Response's from_file now correctly deals with a status line that contains an
HTTP version identifier. HTTP/1.1 200 OK is now correctly parsed, whereas
before this would raise an error upon setting the Response.status in
from_file. See https://github.com/Pylons/webob/issues/121
1.5.0 (2015-10-11)
------------------
Bug Fixes
~~~~~~~~~
- The cookie API functions will now make sure that `max_age` is an integer or
an string that can convert to an integer. Previously passing in
max_age='test' would have silently done the wrong thing.
Features
~~~~~~~~
- Unbreak req.POST when the request method is PATCH. Instead of returning
something cmpletely unrelated we return NoVar. See:
https://github.com/Pylons/webob/pull/215
- HTTP Status Code 308 is now supported as a Permanent Redirect. See
https://github.com/Pylons/webob/pull/207
Backwards Incompatibilities
~~~~~~~~~~~~~~~~~~~~~~~~~~~
- ``Response.set_cookie`` renamed the only required parameter from "key" to
"name". The code will now still accept "key" as a keyword argument, and will
issue a DeprecationWarning until WebOb 1.7.
- The ``status`` attribute of a ``Response`` object no longer takes a string
like ``None None`` and allows that to be set as the status. It now has to at
least match the pattern of ``<integer status code> <explenation of status
code>``. Invalid status strings will now raise a ``ValueError``.
1.5.0a0 (2015-07-25)
--------------------
Backwards Incompatibilities
~~~~~~~~~~~~~~~~~~~~~~~~~~~
- ``Morsel`` will no longer accept a cookie value that does not meet RFC6265's
cookie-octet specification. Upon calling ``Morsel.serialize`` a warning will
be issued, in the future this will raise a ``ValueError``, please update your
cookie handling code. See https://github.com/Pylons/webob/pull/172
The cookie-octet specification in RFC6265 states the following characters are
valid in a cookie value:
=============== =======================================
Hex Range Actual Characters
=============== =======================================
``[0x21 ]`` ``!``
``[0x25-0x2B]`` ``#$%&'()*+``
``[0x2D-0x3A]`` ``-./0123456789:``
``[0x3C-0x5B]`` ``<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[``
``[0x5D-0x7E]`` ``]^_`abcdefghijklmnopqrstuvwxyz{|}~``
=============== =======================================
RFC6265 suggests using base 64 to serialize data before storing data in a
cookie.
Cookies that meet the RFC6265 standard will no longer be quoted, as this is
unnecessary. This is a no-op as far as browsers and cookie storage is
concerned.
- ``Response.set_cookie`` now uses the internal ``make_cookie`` API, which will
issue warnings if cookies are set with invalid bytes. See
https://github.com/Pylons/webob/pull/172
Features
~~~~~~~~
- Add support for some new caching headers, stale-while-revalidate and
stale-if-error that can be used by reverse proxies to cache stale responses
temporarily if the backend disappears. From RFC5861. See
https://github.com/Pylons/webob/pull/189
Bug Fixes
~~~~~~~~~
- Response.status now uses duck-typing for integers, and has also learned to
raise a ValueError if the status isn't an integer followed by a space, and
then the reason. See https://github.com/Pylons/webob/pull/191
- Fixed a bug in ``webob.multidict.GetDict`` which resulted in the
QUERY_STRING not being updated when changes were made to query
params using ``Request.GET.extend()``.
- Read the body of a request if we think it might have a body. This fixes PATCH
to support bodies. See https://github.com/Pylons/webob/pull/184
- Response.from_file returns HTTP headers as latin1 rather than UTF-8, this
fixes the usage on Google AppEngine. See
https://github.com/Pylons/webob/issues/99 and
https://github.com/Pylons/webob/pull/150
- Fix a bug in parsing the auth parameters that contained bad white space. This
makes the parsing fall in line with what's required in RFC7235. See
https://github.com/Pylons/webob/issues/158
- Use '\r\n' line endings in ``Response.__str__``. See:
https://github.com/Pylons/webob/pull/146
Documentation Changes
~~~~~~~~~~~~~~~~~~~~~
- ``response.set_cookie`` now has proper documentation for ``max_age`` and
``expires``. The code has also been refactored to use ``cookies.make_cookie``
instead of duplicating the code. This fixes
https://github.com/Pylons/webob/issues/166 and
https://github.com/Pylons/webob/issues/171
- Documentation didn't match the actual code for the wsgify function signature.
See https://github.com/Pylons/webob/pull/167
- Remove the WebDAV only from certain HTTP Exceptions, these exceptions may
also be used by REST services for example.
1.4 (2014-05-14)
----------------
Features
~~~~~~~~
- Remove ``webob.__version__``, the version number had not been kept in sync
with the official pkg version. To obtain the WebOb version number, use
``pkg_resources.get_distribution('webob').version`` instead.
Bug Fixes
~~~~~~~~~
- Fix a bug in ``EmptyResponse`` that prevents it from setting self.close as
appropriate due to testing truthiness of object rather than if it is
something other than ``None``.
- Fix a bug in ``SignedSerializer`` preventing secrets from containing
higher-order characters. See https://github.com/Pylons/webob/issues/136
- Use the ``hmac.compare_digest`` method when available for constant-time
comparisons.
1.3.1 (2013-12-13)
------------------
Bug Fixes
~~~~~~~~~
- Fix a bug in ``SignedCookieProfile`` whereby we didn't keep the original
serializer around, this would cause us to have ``SignedSerializer`` be added on
top of a ``SignedSerializer`` which would cause it to be run twice when
attempting to verify a cookie. See https://github.com/Pylons/webob/pull/127
Backwards Incompatibilities
~~~~~~~~~~~~~~~~~~~~~~~~~~~
- When ``CookieProfile.get_value`` and ``SignedCookieProfile.get_value`` fails
to deserialize a badly encoded value, we now return ``None`` as if the cookie
was never set in the first place instead of allowing a ``ValueError`` to be
raised to the calling code. See https://github.com/Pylons/webob/pull/126
1.3 (2013-12-10)
----------------
Features
~~~~~~~~
- Added a read-only ``domain`` property to ``BaseRequest``. This property
returns the domain portion of the host value. For example, if the
environment contains an ``HTTP_HOST`` value of ``foo.example.com:8000``,
``request.domain`` will return ``foo.example.com``.
- Added five new APIs: ``webob.cookies.CookieProfile``,
``webob.cookies.SignedCookieProfile``, ``webob.cookies.JSONSerializer`` and
``webob.cookies.SignedSerializer``, and ``webob.cookies.make_cookie``. These
APIs are convenience APIs for generating and parsing cookie headers as well
as dealing with signing cookies.
- Cookies generated via webob.cookies quoted characters in cookie values that
did not need to be quoted per RFC 6265. The following characters are no
longer quoted in cookie values: ``~/=<>()[]{}?@`` . The full set of
non-letter-or-digit unquoted cookie value characters is now
``!#$%&'*+-.^_`|~/: =<>()[]{}?@``. See
http://tools.ietf.org/html/rfc6265#section-4.1.1 for more information.
- Cookie names are now restricted to the set of characters expected by RFC
6265. Previously they could contain unsupported characters such as ``/``.
- Older versions of Webob escaped the doublequote to ``\"`` and the backslash
to ``\\`` when quoting cookie values. Now, instead, cookie serialization
generates ``\042`` for the doublequote and ``\134`` for the backslash. This
is what is expected as per RFC 6265. Note that old cookie values that do
have the older style quoting in them will still be unquoted correctly,
however.
- Added support for draft status code 451 ("Unavailable for Legal Reasons").
See http://tools.ietf.org/html/draft-tbray-http-legally-restricted-status-00
- Added status codes 428, 429, 431 and 511 to ``util.status_reasons`` (they
were already present in a previous release as ``webob.exc`` exceptions).
Bug Fixes
~~~~~~~~~
- MIMEAccept happily parsed malformed wildcard strings like "image/pn*" at
parse time, but then threw an AssertionError during matching. See
https://github.com/Pylons/webob/pull/83 .
- Preserve document ordering of GET and POST request data when POST data passed
to Request.blank is a MultiDict. See https://github.com/Pylons/webob/pull/96
- Allow query strings attached to PATCH requests to populate request.params.
See https://github.com/Pylons/webob/pull/106
- Added Python 3.3 trove classifier.
1.2.3
------------
* Maintainership transferred to `Pylons Project <http://www.pylonsproject.org/>`
* Fix parsing of form submissions where fields have
transfer-content-encoding headers.
1.2.2
------------
* Fix multiple calls to ``cache_expires()`` not fully overriding the
previously set headers.
* Fix parsing of form submissions where fields have different encodings.
1.2.1
------------
* Add index page (e.g., ``index.html``) support for
:class:`webob.static.DirectoryApp`.
* Detect mime-type when creating a test request with file uploads
(``Request.blank("/", POST=dict(file1=("foo.jpg", "xxx")))``)
* Relax parsing of ``Accept`` and ``Range`` headers to allow
uppercase and extra whitespace.
* Fix docs references to some deprecated classes.
1.2
------------
* Fix :mod:`webob.client` handling of connection-refused on Windows.
* Use ``simplejson`` in :mod:`webob.request` if present.
* Fix ``resp.retry_after = <long>`` interpreting value as a UNIX timestamp
(should interpret as time delta in seconds).
1.2rc1
------------
* Add ``Response.json`` and ``Request.json`` which reads and sets the
body using a JSON encoding (previously only the readable attribute
``Request.json_body`` existed). ``Request.json_body`` is still
available as an alias.
* Rename ``Response.status_int`` to ``Response.status_code`` (the
``.status_int`` name is still available and will be supported
indefinitely).
* Add ``Request.text``, the unicode version of the request body
(similar to ``Response.text``).
* Add :mod:`webob.client` which contains the WSGI application
``send_request_app`` and ``SendRequest``. All requests sent to this
application are turned into HTTP requests.
* Renamed ``Request.get_response(app)`` to ``Request.send(app)``. The
``.get_response()`` name is still available.
* Use ``send_request_app`` as the default application for
``Request.send()``, so you can do:
``resp = Request.blank("http://python.org").send()``
* Add :mod:`webob.static` which contains two new WSGI applications,
:class:`FileApp` serve one static file and :class:`DirectoryApp` to serve
the content of a directory. They should provide a reusable implementation
of :doc:`file-example`. It also comes with support for ``wsgi.file_wrapper``.
The implementation has been imported and simplified from
:mod:`PasteOb.fileapp`.
* Add ``dev`` and ``docs`` setup.py aliases (to install development and docs
dependencies respectively, e.g. "python setup.py dev").
1.2b3
------------
* Added ``request.host_port`` API (returns port number implied by HTTP_HOST,
falling back to SERVER_PORT).
* Added ``request.client_addr`` API (returns IP address implied by
HTTP_X_FORWARDED_FOR, falling back to REMOTE_ADDR).
* Fix corner-case ``response.status_int`` and ``response.status`` mutation
bug on py3 (use explicit floor division).
* Backwards incompatibility: Request and BaseRequest objects now return
Unicode for ``request.path_info`` and ``request.script_name`` under Python
2. Rationale: the legacy behavior of returning the respective raw environ
values was nonsensical on Python 3. Working with non-ascii encoded environ
variables as raw WSGI values under Python 3 makes no sense, as PEP 3333
specifies that environ variables are bytes-tunneled-as-latin-1 strings.
If you don't care about Python 3, and you need strict backwards
compatibility, to get legacy behavior of returning bytes on Python 2 for
these attributes, use ``webob.LegacyRequest`` instead of ``webob.Request``.
Although it's possible to use ``webob.LegacyRequest`` under Python 3, it
makes no sense, and it should not be used there.
* The above backwards incompatibility fixed nonsensical behavior of
``request.host_url``, ``request.application_url``, ``request.path_url``,
``request.path``, ``request.path_qs``, ``request.url``,
``request.relative_url``, ``request.path_info_peek``,
``request.path_info_pop`` under Python 3. These methods previously dealt
with raw SCRIPT_NAME and PATH_INFO values, which caused nonsensical
results.
* The WebOb Request object now respects an additional WSGI environment
variable: ``webob.url_encoding``. ``webob.url_encoding`` will be used to
decode the raw WSGI PATH_INFO and SCRIPT_NAME variables when the
``request.path_info`` and ``request.script_name`` APIs are used.
* Request objects now accept an additional constructor parameter:
``url_encoding``. ``url_encoding`` will be used to decode PATH_INFO and
SCRIPT_NAME from its WSGI-encoded values. If ``webob.url_encoding`` is not
set in the environ and ``url_encoding`` is not passed to the Request
constructor, the default value ``utf-8`` will be used to decode the
PATH_INFO and SCRIPT_NAME.
Note that passing ``url_encoding`` will cause the WSGI environment variable
``webob.url_encoding`` to be set.
* Fix ``webob.response._request_uri`` internal function to generate sensible
request URI under Python 3. This fixed a problem under Python 3 if you
were using non-absolute Location headers in responses.
1.2b2
------
* Fix ``request.cookies.get('name', 'default')``. Previously ``default`` was
ignored.
1.2b1
---------
* Mutating the ``request.cookies`` property now reflects the mutations into
the ``HTTP_COOKIES`` environ header.
* ``Response.etag = (tag, False)`` sets weak etag.
* ``Range`` only parses single range now.
* ``Range.satisfiable(..)`` is gone.
* ``Accept.best_matches()`` is gone; use ``list(request.accept)`` or
``request.accept.best_match(..)`` instead (applies to all Accept-*
headers) or similar with ``request.accept_language``.
* ``Response.request`` and ``Response.environ`` attrs are undeprecated and no
longer raise exceptions when used. These can also be passed to the
Response constructor. This is to support codebases that pass them to the
constructor or assign them to a response instance. However, some behavior
differences from 1.1 exist. In particular, synchronization is no longer
done between environ and request attribute properties of Response; you may
pass either to the constructor (or both) or assign one or the other or
both, but they wont be managed specially and will remain the same over the
lifetime of the response just as you passed them. Default values for both
``request`` and ``environ`` on any given response are ``None`` now.
* Undeprecated ``uscript_name`` and ``upath_info``.
* For backwards compatibility purposes, switch ``req.script_name`` and
``path_info`` back again to contain "raw" undecoded native strings rather
than text. Use ``uscript_name`` and ``upath_info`` to get the text version
of SCRIPT_NAME and PATH_INFO.
* Don't raise an exception if ``unicode_errors`` or ``decode_param_names`` is
passed to the Request constructor. Instead, emit a warning. For benefit
of Pylons 1.X, which passes both.
* Don't raise an exception if HTTPException.exception is used; instead emit a
warning. For benefit of Pylons 1.X, which uses it.
1.2a2
---------
* ``req.script_name`` and ``path_info`` now contain text, not bytes.
* Deprecated ``uscript_name`` and ``upath_info``.
* ``charset`` argument to ``Request`` as well as the attribute can only
be set to UTF-8 or the value already present in the ``Content-Type`` header.
* ``unicode_errors`` attribute of ``Request`` and related functionality is gone.
* To process requests that come in an encoding different from UTF-8, the request
needs to be transcoded like this: ``req = req.decode('windows-1251')``
* Added support for weak ETag matching in conditional responses.
* Most of etag-related functionality was refactored.
1.2a1
---------
* Python 3.2 compatibility.
* No longer compatible with Python 2.5 (only 2.6, 2.7, and 3.2 are supported).
* Switched VCS from Mercurial to Git
* Moved development to `GitHub <https://github.com/Pylons/webob>`_
* Added full history from PyCon 2011 sprint to the repository
* Change ``LimitedLengthFile`` and ``FakeCGIBody`` to inherit from
``io.RawIOBase`` and benefit from ``io.BufferedReader``.
* Do not set ``resp.request`` in ``req.get_response(app)``
* ``Response.request`` and ``.environ`` attrs are deprecated and raise exceptions
when used.
* Deprecated request attributes ``str_GET``, ``str_POST``, ``str_cookies`` and
``str_params`` now raise exceptions when touched.
* Remove testing dependency on WebTest.
* Remove UnicodeMultiDict class; the result of ``Request.GET`` and
``Request.POST`` is now just a plain ``MultiDict``.
* The ``decode_param_names`` Request constructor argument has been removed,
along with the ``Request.decode_param_names`` attribute.
* The ``Request.as_string()`` method is now better known as
``Request.as_bytes()``.
* The ``Request.from_string()`` method is now better known as
``Request.from_bytes()``.
* A new method named ``Request.as_text()`` now exists.
* A new method named ``Request.from_text()`` now exists.
* The ``webob.dec.wsgify`` repr() is now much less informative, but a lot
easier to test and maintain.
1.1.1
---------
* Fix disconnect detection being incorrect in some cases (`issue 21
<https://bitbucket.org/ianb/webob/issue/21>`_).
* Fix exception when calling ``.accept.best_match(..)`` on a header containing
``'*'`` (instead of ``'*/*'``).
* Extract some of the ``Accept`` code into subclasses (``AcceptCharset``,
``AcceptLanguage``).
* Improve language matching so that the app can now offer a generic
language code and it will match any of the accepted dialects
(``'en' in AcceptLanguage('en-gb')``).
* Normalize locale names when matching
(``'en_GB' in AcceptLanguage('en-gb')``).
* Deprecate ``etag.weak_match(..)``.
* Deprecate ``Response.request`` and ``Response.environ`` attrs.
1.1
---------
* Remove deprecation warnings for ``unicode_body`` and ``ubody``.
1.1rc1
---------
* Deprecate ``Response.ubody`` / ``.unicode_body`` in favor of new ``.text`` attribute
(the old names will be removed in 1.3 or even later).
* Make ``Response.write`` much more efficient (`issue 18
<https://bitbucket.org/ianb/webob/issue/18>`_).
* Make sure copying responses does not reset Content-Length or Content-MD5 of the
original (and that of future copies).
* Change ``del res.body`` semantics so that it doesn't make the response invalid,
but only removes the response body.
* Remove ``Response._body`` so the ``_app_iter`` is the only representation.
1.1b2
---------
* Add detection for browser / user-agent disconnects. If the client disconnected
before sending the entire request body (POST / PUT), ``req.POST``, ``req.body``
and other related properties and methods will raise an exception.
Previously this caused the application get a truncated request with no indication that it
is incomplete.
* Make ``Response.body_file`` settable. This is now valid:
``Response(body_file=open('foo.bin'), content_type=...)``
* Revert the restriction on req.body not being settable for GET and some
other requests. Such requests actually can have a body according to HTTP BIS
(see also `commit message <https://bitbucket.org/ianb/webob/changeset/b3ef34c57936>`_)
* Add support for file upload testing via ``Request.blank(POST=..)``. Patch contributed by
Tim Perevezentsev. See also:
`ticket <https://bitbucket.org/ianb/webob/issue/15>`_,
`changeset <https://bitbucket.org/ianb/webob/changeset/4ba9ab0c3f99>`_.
* Deprecate ``req.str_GET``, ``str_POST``, ``str_params`` and ``str_cookies`` (warning).
* Deprecate ``req.decode_param_names`` (warning).
* Change ``req.decode_param_names`` default to ``True``. This means that ``.POST``, ``.GET``,
``.params`` and ``.cookies`` keys are now unicode. This is necessary for WebOb to behave
as close as possible on Python 2 and Python 3.
1.1b1
---------
* We have acquired the webob.org domain, docs are now hosted at `docs.webob.org
<http://docs.webob.org/>`_
* Make ``accept.quality(..)`` return best match quality, not first match quality.
* Fix ``Range.satisfiable(..)`` edge cases.
* Make sure ``WSGIHTTPException`` instances return the same headers for ``HEAD``
and ``GET`` requests.
* Drop Python 2.4 support
* Deprecate ``HTTPException.exception`` (warning on use).
* Deprecate ``accept.first_match(..)`` (warning on use).
Use ``.best_match(..)`` instead.
* Complete deprecation of ``req.[str_]{post|query}vars`` properties
(exception on use).
* Remove ``FakeCGIBody.seek`` hack (no longer necessary).
1.0.8
------
* Escape commas in cookie values (see also:
`stdlib Cookie bug <http://bugs.python.org/issue9824>`_)
* Change cookie serialization to more closely match how cookies usually
are serialized (unquoted expires, semicolon separators even between morsels)
* Fix some rare cases in cookie parsing
* Enhance the req.is_body_readable to always guess GET, HEAD, DELETE and TRACE
as unreadable and PUT and POST as readable
(`issue 12 <https://bitbucket.org/ianb/webob/issue/12>`_)
* Deny setting req.body or req.body_file to non-empty values for GET, HEAD and
other bodiless requests
* Fix running nosetests with arguments on UNIX systems
(`issue 11 <https://bitbucket.org/ianb/webob/issue/11>`_)
1.0.7
------
* Fix ``Accept`` header matching for items with zero-quality
(`issue 10 <https://bitbucket.org/ianb/webob/issue/10>`_)
* Hide password values in ``MultiDict.__repr__``
1.0.6
------
* Use ``environ['wsgi.input'].read()`` instead of ``.read(-1)`` because the former
is explicitly mentioned in PEP-3333 and CherryPy server does not support the latter.
* Add new ``environ['webob.is_body_readable']`` flag which specifies if the
input stream is readable even if the ``CONTENT_LENGTH`` is not set.
WebOb now only ever reads the input stream if the content-length is known
or this flag is set.
* The two changes above fix a hangup with CherryPy and wsgiref servers
(`issue 6 <https://bitbucket.org/ianb/webob/issue/6>`_)
* ``req.body_file`` is now safer to read directly. For ``GET`` and other similar requests
it returns an empty ``StringIO`` or ``BytesIO`` object even if the server passed in
something else.
* Setting ``req.body_file`` to a string now produces a PendingDeprecationWarning.
It will produce DeprecationWarning in 1.1 and raise an error in 1.2. Either
set ``req.body_file`` to a file-like object or set ``req.body`` to a string value.
* Fix ``.pop()`` and ``.setdefault(..)`` methods of ``req/resp.cache_control``
* Thanks to the participants of `Pyramid sprint at the PyCon US 2011
<https://bitbucket.org/ianb/webob/changeset/7b7dc3ec6159>`_ WebOb now has
100% test coverage.
1.0.5
------
* Restore Python 2.4 compatibility.
1.0.4
------
* The field names escaping bug semi-fixed in 1.0.3 and originally blamed on cgi module
was in fact a ``webob.request._encode_multipart`` bug (also in Google Chrome) and was
lurking in webob code for quite some time -- 1.0.2 just made it trigger more often.
Now it is fixed properly.
* Make sure that req.url and related properties do not unnecessarily escape some chars
(``:@&+$``) in the URI path (`issue 5 <https://bitbucket.org/ianb/webob/issue/5>`_)
* Revert some changes from 1.0.3 that have broken backwards compatibility for some apps.
Getting ``req.body_file`` does not make input stream seekable, but there's a new property
``req.body_file_seekable`` that does.
* ``Request.get_response`` and ``Request.call_application`` seek the input body to start
before calling the app (if possible).
* Accessing ``req.body`` 'rewinds' the input stream back to pos 0 as well.
* When accessing ``req.POST`` we now avoid making the body seekable as the input stream data
are preserved in ``FakeCGIBody`` anyway.
* Add new method ``Request.from_string``.
* Make sure ``Request.as_string()`` uses CRLF to separate headers.
* Improve parity between ``Request.as_string()`` and ``.from_file``/``.from_string``
methods, so that the latter can parse output of the former and create a similar
request object which wasn't always the case previously.
1.0.3
------
* Correct a caching issue introduced in WebOb 1.0.2 that was causing unnecessary reparsing
of POST requests.
* Fix a bug regarding field names escaping for forms submitted as ``multipart/form-data``.
For more infromation see `the bug report and discussion
<https://bitbucket.org/ianb/webob/issue/2>`_ and 1.0.4 notes for further fix.
* Add ``req.http_version`` attribute.
1.0.2
------
* Primary maintainer is now `Sergey Schetinin <http://self.maluke.com/>`_.
* Issue tracker moved from `Trac <http://bit.ly/webob-tickets>`_ to bitbucket's `issue
tracker <https://bitbucket.org/ianb/webob/issues>`_
* WebOb 1.0.1 changed the behavior of ``MultiDict.update`` to be more in line with
other dict-like objects. We now also issue a warning when we detect that the
client code seems to expect the old, extending semantics.
* Make ``Response.set_cookie(key, None)`` set the 'delete-cookie' (same as ``.delete_cookie(key)``)
* Make ``req.upath_info`` and ``req.uscript_name`` settable
* Add :meth:``Request.as_string()`` method
* Add a ``req.is_body_seekable`` property
* Support for the ``deflate`` method with ``resp.decode_content()``
* To better conform to WSGI spec we no longer attempt to use seek on ``wsgi.input`` file
instead we assume it is not seekable unless ``env['webob.is_body_seekable']`` is set.
When making the body seekable we set that flag.
* A call to ``req.make_body_seekable()`` now guarantees that the body is seekable, is at 0 position
and that a correct ``req.content_length`` is present.
* ``req.body_file`` is always seekable. To access ``env['wsgi.input']`` without any processing,
use ``req.body_file_raw``. (Partially reverted in 1.0.4)
* Fix responses to HEAD requests with Range.
* Fix ``del resp.content_type``, ``del req.body``, ``del req.cache_control``
* Fix ``resp.merge_cookies()`` when called with an argument that is not a Response instance.
* Fix ``resp.content_body = None`` (was removing Cache-Control instead)
* Fix ``req.body_file = f`` setting ``CONTENT_LENGTH`` to ``-1`` (now removes from environ)
* Fix: make sure req.copy() leaves the original with seekable body
* Fix handling of WSGI environs with missing ``SCRIPT_NAME``
* A lot of tests were added by Mariano Mara and Danny Navarro.
1.0.1
-----
* As WebOb requires Python 2.4 or later, drop some compatibility modules
and update the code to use the decorator syntax.
* Implement optional on-the-fly response compression (``resp.encode_content(lazy=True)``)
* Drop ``util.safezip`` module and make ``util`` a module instead of a subpackage.
Merge ``statusreasons`` into it.
* Instead of using stdlib ``Cookie`` with monkeypatching, add a derived
but thoroughly rewritten, cleaner, safer and faster ``webob.cookies`` module.
* Fix: ``Response.merge_cookies`` now copies the headers before modification instead of
doing it in-place.
