:alt: Documentation Status
This package allows you to publish Python objects on the web. It
has support for plain HTTP/WebDAV clients, web browsers as well as
XML-RPC and FTP clients. Input and output streams are represented by
request and response objects which allow for easy client interaction
from Python. The behaviour of the publisher is geared towards WSGI
compatibility.

Changes
=========
7.1 (2024-09-27)
================
- Drop support for Python 3.7.
- Add support for Python 3.12, 3.13.
- Fix test suite to use proper line endings (``\r\n``) in raw multipart/form-data
HTTP requests, because multipart 1.0.0 is stricter about line endings.
Fixes `issue #74 <https://github.com/zopefoundation/zope.publisher/issues/74>`_.
- ``FileUpload`` objects now implement a fallback ``seekable()`` method on
Python 3.7 through 3.10, where tempfile.SpooledTemporaryFile lacks it.
Fixes `issue 44 <https://github.com/zopefoundation/zope.publisher/issues/44>`_
again, which had regressed due to certain assumptions that were no longer
true after the multipart 1.0.0 release.
7.0 (2023-08-29)
================
- Drop support for Python 2.7, 3.5, 3.6.
- Drop support for ``im_func`` and ``func_code``.
- Add support for Python 3.11.
6.1.0 (2022-03-15)
==================
- Revamp handling of query string and form decoding in ``BrowserRequest``.
The previous approach was to tell underlying libraries to decode inputs
using ISO-8859-1, then re-encode as ISO-8859-1 and decode using an
encoding deduced from the ``Accept-Charset`` request header. However,
this didn't make much conceptual sense (since ``Accept-Charset`` defines
the preferred *response* encoding), and it made it impossible to handle
cases where the encoding was specified as something other than ISO-8859-1
in the request (which might even be on a per-item basis, in the case of
``multipart/form-data`` input).
We now only perform the dubious ``Accept-Charset`` guessing for query
strings; in other cases we let ``multipart`` determine the encoding,
defaulting to UTF-8 as per the HTML specification. For cases where
applications need to specify some other default form encoding,
``BrowserRequest`` subclasses can now set ``default_form_charset``.
See `issue 65
<https://github.com/zopefoundation/zope.publisher/issues/65>`_.
- Add support for Python 3.10.
6.0.2 (2021-06-07)
==================
- Avoid traceback reference cycle in ``zope.publisher.publish.publish``.
- Handle empty Content-Type environment variable gracefully.
6.0.1 (2021-04-15)
==================
- Fix test compatibility with zope.interface 5.4.
6.0.0 (2021-01-20)
==================
- Port form data parsing to ``multipart``, which is a new dependency. See
`issue 39 <https://github.com/zopefoundation/zope.publisher/issues/39>`_.
Note that as a result ``FileUpload`` objects no longer have a ``name``
attribute: the ``name`` attribute couldn't be used in portable code in any
case, and the usual methods on open files should be used instead.
- Add support for Python 3.9.
5.2.1 (2020-06-15)
==================
- Fix text/bytes handling on Python 3 for some response edge cases. See
`pull request 51
<https://github.com/zopefoundation/zope.publisher/pull/51>`_.
5.2.0 (2020-03-30)
==================
- Add support for Python 3.8.
- Ensure all objects have a consistent interface resolution order. See
`issue 49
<https://github.com/zopefoundation/zope.publisher/issues/49>`_.
- Drop support for the deprecated ``python setup.py test`` command.
5.1.1 (2019-08-08)
==================
- Avoid using ``urllib.parse.splitport()`` which was deprecated in Python 3.8.
See `issue 38 <https://github.com/zopefoundation/zope.publisher/issues/38>`_
5.1.0 (2019-07-12)
==================
- Drop support for Python 3.4.
- ``FileUpload`` objects now support the ``seekable()`` method on Python 3.
Fixes `issue 44 <https://github.com/zopefoundation/zope.publisher/issues/44>`_.
- Character set handling was rather comprehensively broken on Python 3.
It should be fixed now. See `issue 41
<https://github.com/zopefoundation/zope.publisher/issues/41>`_.
5.0.1 (2018-10-19)
==================
- Fix a ``DeprecationWarning``.
5.0.0 (2018-10-10)
===================
- Backwards incompatible change: Remove ``zope.publisher.tests.httprequest``.
It is not used inside this package and was never ported to Python 3.
Fixes https://github.com/zopefoundation/zope.publisher/issues/4.
- Add support for Python 3.7 and PyPy3.
- Drop support for Python 3.3.
- Fix ``XMLRPCResponse`` having a str body (instead of a bytes body)
which could lead to ``TypeError`` on Python 3. See `issue 26
<https://github.com/zopefoundation/zope.publisher/issues/26>`_.
4.3.2 (2017-05-23)
==================
- Fix instances of ``BaseRequest`` (including ``BrowserRequest``)
being unexpectedly ``False`` on Python 3 by defining ``__bool__``.
Such instances were always ``True`` on Python 2. See `issue 18
<https://github.com/zopefoundation/zope.publisher/issues/18>`_.
4.3.1 (2017-04-24)
==================
- Add support for Python 3.6.
- Accept both new and old locations for ``__code__`` in
``zope.publisher.publisher.unwrapMethod``. This restores compatibility with
Products.PythonScripts, where parameters were not extracted.
[maurits, thet, MatthewWilkes]
- Fix file uploads on python 3.4 and up. cgi.FieldStorage explicitly
closes files when it is garbage collected. For details, see:
* http://bugs.python.org/issue18394
* https://hg.python.org/cpython/rev/c0e9ba7b26d5
* https://github.com/zopefoundation/zope.publisher/pull/13
We now keep a reference to the FieldStorage till we are finished
processing the request.
- Fix POST with large values on Python 3. Related to cgi.FieldStorage
doing the decoding in Python 3. See `pull 16
<https://github.com/zopefoundation/zope.publisher/pull/16>`_.
4.3.0 (2016-07-04)
==================
- Add support for Python 3.5.
- Drop support for Python 2.6 and 3.2.
4.2.2 (2015-11-16)
==================
- Emit HTTP response headers in a deterministic order (GH #8).
4.2.1 (2015-06-05)
==================
- Add support for Python 3.2.
4.2.0 (2015-06-02)
==================
- Add support for PyPy and PyPy3.
4.1.0 (2014-12-27)
==================
- Add support for Python 3.4.
4.0.0 (2014-12-22)
==================
- Add ``__traceback_info__`` to ``response.redirect()`` to ease debugging
untrusted redirects.
- Add ``trusted`` support for ``Redirect`` exception
4.0.0a4 (2013-03-12)
====================
- Support UTF-8-encoding application/json responses returned as Unicode.
4.0.0a3 (2013-02-28)
====================
- Return bytes from ``PrincipalLogging.getLogMessage`` instead of unicode.
4.0.0a2 (2013-02-22)
====================
- Use BytesIO in ``zope.publisher.xmlrpc.TestRequest``.
4.0.0a1 (2013-02-21)
====================
- Replace deprecated ``zope.component.adapts`` usage with equivalent
``zope.component.adapter`` decorator.
- Replace deprecated ``zope.interface.implements`` usage with equivalent
``zope.interface.implementer`` decorator.
- Drop support for Python 2.4, 2.5 and pypy.
- Add support for Python 3.3.
- Wrap ``with interaction()`` in try/finally.
- Don't guess the content type with 304 responses which MUST NOT /
SHOULD NOT include it according to:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5
Unfortunately, the content type will still be guessed if the result is
set before the status.
3.13.0 (2011-11-17)
===================
- Fix error when no charset matches form data and HTTP_ACCEPT_CHARSET contains a ``*``.
- Add test convenience helper ``create_interaction`` and ``with interaction()``.
3.12.6 (2010-12-17)
===================
- Upload a non-CRLF version to pypi.
3.12.5 (2010-12-14)
===================
- Rename the ``tests`` extra to ``test``.
- Add a test for our own configure.zcml.
- Use UTF-8 as the charset if the browser does not set a header,
per W3C spec.
3.12.4 (2010-07-15)
===================
- LP #131460: Make principal logging unicode safe.
- Remove use of string exceptions in tests, http://bugs.debian.org/585343
- Add ``IStartRequestEvent`` and ``StartRequestEvent`` for use in
``zope.app.publication`` (matching up with ``IEndRequestEvent`` and
``EndRequestEvent``). Includes refactoring to produce one definition of
'event with a request' - IRequestEvent.
3.12.3 (2010-04-30)
===================
- LP #209440: Don't obscure original exception when handling retries
in ``publish.publish()`` with ``handleErrors == False``. This change
makes debugging such exception in unit tests easier.
Thanks to James Henstridge for the patch.
- LP #98395: allow unicode output of XML content whose mimetype does not
begin with ``text/``, per RFC 3023 as well as for content types ending
in ``+xml`` such as Mozilla XUL's ``application/vnd+xml``. Thanks to
Justin Ryan for the patch.
3.12.2 (2010-04-16)
===================
- Remove use of ``zope.testing.doctestunit`` in favor of stdlib's ``doctest``.
- Fix bug where xml-rpc requests would hang when served using
``paster.httpserver``.
3.12.1 (2010-02-21)
===================
- Ensure that ``BaseRequest.traverse`` does not call traversal hooks on
elements previously traversed but wrapped in a security proxy.
3.12.0 (2009-12-31)
===================
- Revert change done in 3.6.2, removing the ``zope.authentication``
dependency again. Move the ``BasicAuthAdapter`` and ``FTPAuth`` adapters
to the new ``zope.login`` package.
3.11.0 (2009-12-15)
===================
- Move ``EndRequestEvent`` and ``IEndRequestEvent`` here from
``zope.app.publication``.
3.10.1 (2009-11-28)
===================
- Declare minimum dependency on ``zope.contenttype`` 3.5 (omitted in 3.10).
3.10.0 (2009-10-22)
===================
- Move the implementation of ``zope.publisher.contenttype`` to
``zope.contenttype.parse``, leaving BBB imports and moving tests along.
``zope.contenttype`` is a new but light-weight dependency of this package.
- Support Python 2.6 by keeping QUERY_STRING out of request.form if
the method is a POST. The original QUERY_STRING is still available if
further processing is needed.
- Better support the zcml ``defaultSkin`` directive's behavior (registering
an interface as a default skin) in the ``setDefaultSkin`` function.
3.9.3 (2009-10-08)
==================
- Fix the check for untrusted redirects introduced in 3.9.0 so it works with
virtual hosting.
3.9.2 (2009-10-07)
==================
- Make redirect validation works without HTTP_HOST variable.
- Add DoNotReRaiseException adapter that can be registered
for exceptions to flag that they should not be re-raised by
publisher when ``handle_errors`` parameter of the ``publish``
method is False.
3.9.1 (2009-09-01)
==================
- Convert a location, passed to a redirect method of HTTPRequest to
string before checking for trusted host redirection, because a
location object may be some non-string convertable to string, like
URLGetter.
3.9.0 (2009-08-27)
==================
- Move some parts of ``zope.app.publisher`` into this package
during ``zope.app.publisher`` refactoring:
* ``IModifiableUserPreferredLanguages`` adapter for requests
* ``browser:defaultView`` and ``browser:defaultSkin`` ZCML directives
* ``IHTTPView``, ``IXMLRPCView`` and like interfaces
* security ZCML declarations for some of ``zope.publisher`` classes
- Introduce ``IReRaiseException`` interface. If during publishing an
exception occurs and for this exception an adapter is available that
returns ``False`` on being called, the exception won't be reraised
by the publisher. This happens only if ``handle_errors`` parameter
of the ``publish()`` method is set to ``False``. Fixes problems when
acting in a WSGI pipeline with a debugger middleware enabled.
See https://bugs.launchpad.net/grok/+bug/332061 for details.
- Fix #98471: Restrict redirects to current host. This causes a ValueError to
be raised in the case of redirecting to a different host. If this is
intentional, the parameter `trusted` can be given.
- Move dependency on ``zope.testing`` from ``install_requires`` to
``tests_require``.
- Remove ``time.sleep`` in the ``supportsRetry`` http request.
- Add a fix for Internet Explorer versions which upload files with full
filesystem paths as filenames.
3.8.0 (2009-05-23)
==================
- Move ``IHTTPException``, ``IMethodNotAllowed``, and ``MethodNotAllowed``
here from ``zope.app.http``, fixing dependency cycles involving
``zope.app.http``.
- Move the ``DefaultViewName`` API here from ``zope.app.publisher.browser``,
making it accessible to other packages that need it.
3.7.0 (2009-05-13)
==================
- Move ``IView`` and ``IBrowserView`` interfaces into
``zope.browser.interfaces``, leaving BBB imports.
3.6.4 (2009-04-26)
==================
- Add some BBB code to setDefaultSkin to allow IBrowserRequest's to continue
to work without configuring any special adapter for IDefaultSkin.
- Move `getDefaultSkin` to the skinnable module next to the `setDefaultSkin`
method, leaving a BBB import in place. Mark `IDefaultBrowserLayer` as a
`IBrowserSkinType` in code instead of relying on the ZCML to be loaded.
3.6.3 (2009-03-18)
==================
- Mark HTTPRequest as IAttributeAnnotatable if ``zope.annotation`` is
available, this was previously done by ``zope.app.i18n``.
- Register `IHTTPRequest` -> `IUserPreferredCharsets` adapter in ZCML
configuration. This was also previously done by ``zope.app.i18n``.
3.6.2 (2009-03-14)
==================
- Add an adapter from ``zope.security.interfaces.IPrincipal`` to
``zope.publisher.interfaces.logginginfo.ILoggingInfo``. It was moved
from ``zope.app.security`` as a part of refactoring process.
- Add adapters from HTTP and FTP request to
``zope.authentication.ILoginPassword`` interface. They are moved from
``zope.app.security`` as a part of refactoring process. This change adds a
dependency on the ``zope.authentication`` package, but it's okay, since it's
a tiny contract definition-only package.
See http://mail.zope.org/pipermail/zope-dev/2009-March/035325.html for
reasoning.
3.6.1 (2009-03-09)
==================
- Fix: remove IBrowserRequest dependency in http implementation based on
condition for setDefaultSkin. Use ISkinnable instead of IBrowserRequest.
3.6.0 (2009-03-08)
==================
- Clean-up: Move skin related code from zope.publisher.interfaces.browser and
zope.publisher.browser to zope.publihser.interfaces and
zope.publisher.skinnable and provide BBB imports. See skinnable.txt for more
information.
- Fix: ensure that we only apply skin interface in setDefaultSkin which also
provide IBrowserSkinType. This will ensure that we find a skin if the
applySkin method will lookup for a skin based on this type interface.
- Fix: Make it possible to use adapters and not only interfaces as skins from
the adapter registry. Right now the defaultSkin directive registers simple
interfaces as skin adapters which will run into a TypeError if someone tries
to adapter such a skin adapter. Probably we should change the defaultSkin
directive and register real adapters instead of using the interfaces as fake
adapters where we expect adapter factories.
- Feature: allow use of ``applySkinof`` with different skin types using the
optional ``skinType`` argument, which is by default set to
``IBrowserSkinType``.
- Feature: implement the default skin pattern within adapters. This allows
us to register default skins for other requests then only
``IBrowserRequest`` using ``IDefaultSkin`` adapters.
Note, ``ISkinnable`` and ``ISkinType`` and the skin implementation should
be moved out of the browser request modules. Packages like ``z3c.jsonrpc``
do not depend on ``IBrowserRequest`` but they are skinnable.
- Feature: add ``ISkinnable`` interface which allows us to implement the apply
skin pattern not only for ``IBrowserRequest``.
- Fix: Don't cause warnings on Python 2.6
- Fix: Make ``IBrowserPage`` inherit ``IBrowserView``.
- Move ``IView`` and ``IDefaultViewName`` here from
``zope.component.interfaces``. Stop inheriting from deprecated (for years)
interfaces defined in ``zope.component``.
- Remove deprecated code.
- Clean-up: Move ``zope.testing`` from extras to dependencies, per Zope
Framework policy. Remove ``zope.app.testing`` as a dependency: tests run
fine without it.
3.5.6 (2009-02-14)
==================
- Fix an untested code path that incorrectly attempted to construct a
``NotFound``, adding a test.
3.5.5 (2009-02-04)
==================
- LP #322486: ``setStatus()`` now allows any ``int()``-able status value.
3.5.4 (2008-09-22)
==================
- LP #98440: interfaces lost on retried request
- LP #273296: dealing more nicely with malformed HTTP_ACCEPT_LANGUAGE headers
within getPreferredLanguages().
- LP #253362: dealing more nicely with malformed HTTP_ACCEPT_CHARSET headers
within getPreferredCharsets().
- LP #98284: Pass the ``size`` argument to readline, as the version of
twisted used in zope.app.twisted supports it.
- Fix the LP #98284 fix: do not pass ``size`` argument of None that causes
cStringIO objects to barf with a TypeError.
3.5.3 (2008-06-20)
==================
- It turns out that some Web servers (Paste for example) do not send the EOF
character after the data has been transmitted and the read() of the cached
stream simply hangs if no expected content length has been specified.
3.5.2 (2008-04-06)
==================
- A previous fix to handle posting of non-form data broke handling of
form data with extra information in the content type, as in::
application/x-www-form-urlencoded; charset=UTF-8
3.5.1 (2008-03-23)
==================
- When posting non-form (and non-multipart) data, the request body was
consumed and discarded. This makes it impossible to deal with other
post types, like xml-rpc or json without resorting to overly complex
"request factory" contortions.
- https://bugs.launchpad.net/zope2/+bug/143873
``zope.publisher.http.HTTPCharsets`` was confused by the Zope 2
publisher, which gives misleading information about which headers
it has.
3.5.0 (2008-03-02)
==================
- Added a PasteDeploy app_factory implementation. This should make
it easier to integrate Zope 3 applications with PasteDeploy. It
also makes it easier to control the publication used, giving far
greater control over application policies (e.g. whether or not to
use the ZODB).
3.4.2 (2007-12-07)
==================
- Made segmentation of URLs not strip (trailing) whitespace from path segments
to allow URLs ending in %20 to be handled correctly. (#172742)
3.4.1 (2007-09-29)
==================
No changes since 3.4.1b2.
3.4.1b2 (2007-08-02)
====================
- Add support for Python 2.5.
- Fix a problem with ``request.get()`` when the object that's to be
retrieved is the request itself.
3.4.1b1 (2007-07-13)
====================
No changes.
3.4.0b2 (2007-07-05)
====================
- LP #122054: ``HTTPInputStream`` understands both the CONTENT_LENGTH and
HTTP_CONTENT_LENGTH environment variables. It is also now tolerant
of empty strings and will treat those as if the variable were
absent.
3.4.0b1 (2007-07-05)
====================
- Fix caching issue. The input stream never got cached in a temp file
because of a wrong content-length header lookup. Added CONTENT_LENGTH
header check in addition to the previous used HTTP_CONTENT_LENGTH. The
``HTTP_`` prefix is sometimes added by some CGI proxies, but CONTENT_LENGTH
is the right header info for the size.
- LP #98413: ``HTTPResponse.handleException`` should set the content type
3.4.0a1 (2007-04-22)
====================
Initial release as a separate project, corresponds to zope.publisher
from Zope 3.4.0a1

See\n `issue 49\n <https://github.com/zopefoundation/zope.publisher/issues/49>`_.\n\n- Drop support for the deprecated ``python setup.py test`` command.\n\n5.1.1 (2019-08-08)\n==================\n\n- Avoid using ``urllib.parse.splitport()`` which was deprecated in Python 3.8.\n See `issue 38 <https://github.com/zopefoundation/zope.publisher/issues/38>`_\n\n\n5.1.0 (2019-07-12)\n==================\n\n- Drop support for Python 3.4.\n\n- ``FileUpload`` objects now support the ``seekable()`` method on Python 3.\n Fixes `issue 44 <https://github.com/zopefoundation/zope.publisher/issues/44>`_.\n\n- Character set handling was rather comprehensively broken on Python 3.\n It should be fixed now. See `issue 41\n <https://github.com/zopefoundation/zope.publisher/issues/41>`_.\n\n\n5.0.1 (2018-10-19)\n==================\n\n- Fix a ``DeprecationWarning``.\n\n\n5.0.0 (2018-10-10)\n===================\n\n- Backwards incompatible change: Remove ``zope.publisher.tests.httprequest``.\n It is not used inside this package and was never ported to Python 3.\n Fixes https://github.com/zopefoundation/zope.publisher/issues/4.\n\n- Add support for Python 3.7 and PyPy3.\n\n- Drop support for Python 3.3.\n\n- Fix ``XMLRPCResponse`` having a str body (instead of a bytes body)\n which could lead to ``TypeError`` on Python 3. See `issue 26\n <https://github.com/zopefoundation/zope.publisher/issues/26>`_.\n\n\n4.3.2 (2017-05-23)\n==================\n\n- Fix instances of ``BaseRequest`` (including ``BrowserRequest``)\n being unexpectedly ``False`` on Python 3 by defining ``__bool__``.\n Such instances were always ``True`` on Python 2. See `issue 18\n <https://github.com/zopefoundation/zope.publisher/issues/18>`_.\n\n\n4.3.1 (2017-04-24)\n==================\n\n- Add support for Python 3.6.\n\n- Accept both new and old locations for ``__code__`` in\n ``zope.publisher.publisher.unwrapMethod``. This restores compatibility with\n Products.PythonScripts, where parameters were not extracted.\n [maurits, thet, MatthewWilkes]\n\n- Fix file uploads on python 3.4 and up. cgi.FieldStorage explicitly\n closes files when it is garbage collected. For details, see:\n\n * http://bugs.python.org/issue18394\n * https://hg.python.org/cpython/rev/c0e9ba7b26d5\n * https://github.com/zopefoundation/zope.publisher/pull/13\n\n We now keep a reference to the FieldStorage till we are finished\n processing the request.\n\n- Fix POST with large values on Python 3. Related to cgi.FieldStorage\n doing the decoding in Python 3. See `pull 16\n <https://github.com/zopefoundation/zope.publisher/pull/16>`_.\n\n4.3.0 (2016-07-04)\n==================\n\n- Add support for Python 3.5.\n\n- Drop support for Python 2.6 and 3.2.\n\n\n4.2.2 (2015-11-16)\n==================\n\n- Emit HTTP response headers in a deterministic order (GH #8).\n\n4.2.1 (2015-06-05)\n==================\n\n- Add support for Python 3.2.\n\n4.2.0 (2015-06-02)\n==================\n\n- Add support for PyPy and PyPy3.\n\n4.1.0 (2014-12-27)\n==================\n\n- Add support for Python 3.4.\n\n4.0.0 (2014-12-22)\n==================\n\n- Add ``__traceback_info__`` to ``response.redirect()`` to ease debugging\n untrusted redirects.\n\n- Add ``trusted`` support for ``Redirect`` exception\n\n4.0.0a4 (2013-03-12)\n====================\n\n- Support UTF-8-encoding application/json responses returned as Unicode.\n\n4.0.0a3 (2013-02-28)\n====================\n\n- Return bytes from ``PrincipalLogging.getLogMessage`` instead of unicode.\n\n4.0.0a2 (2013-02-22)\n====================\n\n- Use BytesIO in ``zope.publisher.xmlrpc.TestRequest``.\n\n4.0.0a1 (2013-02-21)\n====================\n\n- Replace deprecated ``zope.component.adapts`` usage with equivalent\n ``zope.component.adapter`` decorator.\n\n- Replace deprecated ``zope.interface.implements`` usage with equivalent\n ``zope.interface.implementer`` decorator.\n\n- Drop support for Python 2.4, 2.5 and pypy.\n\n- Add support for Python 3.3.\n\n- Wrap ``with interaction()`` in try/finally.\n\n- Don't guess the content type with 304 responses which MUST NOT /\n SHOULD NOT include it according to:\n http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5\n\n Unfortunately, the content type will still be guessed if the result is\n set before the status.\n\n3.13.0 (2011-11-17)\n===================\n\n- Fix error when no charset matches form data and HTTP_ACCEPT_CHARSET contains a ``*``.\n\n- Add test convenience helper ``create_interaction`` and ``with interaction()``.\n\n\n3.12.6 (2010-12-17)\n===================\n\n- Upload a non-CRLF version to pypi.\n\n\n3.12.5 (2010-12-14)\n===================\n\n- Rename the ``tests`` extra to ``test``.\n\n- Add a test for our own configure.zcml.\n\n- Use UTF-8 as the charset if the browser does not set a header,\n per W3C spec.\n\n3.12.4 (2010-07-15)\n===================\n\n- LP #131460: Make principal logging unicode safe.\n\n- Remove use of string exceptions in tests, http://bugs.debian.org/585343\n\n- Add ``IStartRequestEvent`` and ``StartRequestEvent`` for use in\n ``zope.app.publication`` (matching up with ``IEndRequestEvent`` and\n ``EndRequestEvent``). Includes refactoring to produce one definition of\n 'event with a request' - IRequestEvent.\n\n3.12.3 (2010-04-30)\n===================\n\n- LP #209440: Don't obscure original exception when handling retries\n in ``publish.publish()`` with ``handleErrors == False``. This change\n makes debugging such exception in unit tests easier.\n Thanks to James Henstridge for the patch.\n\n- LP #98395: allow unicode output of XML content whose mimetype does not\n begin with ``text/``, per RFC 3023 as well as for content types ending\n in ``+xml`` such as Mozilla XUL's ``application/vnd+xml``. Thanks to\n Justin Ryan for the patch.\n\n3.12.2 (2010-04-16)\n===================\n\n- Remove use of ``zope.testing.doctestunit`` in favor of stdlib's ``doctest``.\n\n- Fix bug where xml-rpc requests would hang when served using\n ``paster.httpserver``.\n\n3.12.1 (2010-02-21)\n===================\n\n- Ensure that ``BaseRequest.traverse`` does not call traversal hooks on\n elements previously traversed but wrapped in a security proxy.\n\n3.12.0 (2009-12-31)\n===================\n\n- Revert change done in 3.6.2, removing the ``zope.authentication``\n dependency again. Move the ``BasicAuthAdapter`` and ``FTPAuth`` adapters\n to the new ``zope.login`` package.\n\n3.11.0 (2009-12-15)\n===================\n\n- Move ``EndRequestEvent`` and ``IEndRequestEvent`` here from\n ``zope.app.publication``.\n\n3.10.1 (2009-11-28)\n===================\n\n- Declare minimum dependency on ``zope.contenttype`` 3.5 (omitted in 3.10).\n\n3.10.0 (2009-10-22)\n===================\n\n- Move the implementation of ``zope.publisher.contenttype`` to\n ``zope.contenttype.parse``, leaving BBB imports and moving tests along.\n ``zope.contenttype`` is a new but light-weight dependency of this package.\n\n- Support Python 2.6 by keeping QUERY_STRING out of request.form if\n the method is a POST. The original QUERY_STRING is still available if\n further processing is needed.\n\n- Better support the zcml ``defaultSkin`` directive's behavior (registering\n an interface as a default skin) in the ``setDefaultSkin`` function.\n\n3.9.3 (2009-10-08)\n==================\n\n- Fix the check for untrusted redirects introduced in 3.9.0 so it works with\n virtual hosting.\n\n3.9.2 (2009-10-07)\n==================\n\n- Make redirect validation works without HTTP_HOST variable.\n\n- Add DoNotReRaiseException adapter that can be registered\n for exceptions to flag that they should not be re-raised by\n publisher when ``handle_errors`` parameter of the ``publish``\n method is False.\n\n3.9.1 (2009-09-01)\n==================\n\n- Convert a location, passed to a redirect method of HTTPRequest to\n string before checking for trusted host redirection, because a\n location object may be some non-string convertable to string, like\n URLGetter.\n\n3.9.0 (2009-08-27)\n==================\n\n- Move some parts of ``zope.app.publisher`` into this package\n during ``zope.app.publisher`` refactoring:\n\n * ``IModifiableUserPreferredLanguages`` adapter for requests\n * ``browser:defaultView`` and ``browser:defaultSkin`` ZCML directives\n * ``IHTTPView``, ``IXMLRPCView`` and like interfaces\n * security ZCML declarations for some of ``zope.publisher`` classes\n\n- Introduce ``IReRaiseException`` interface. If during publishing an\n exception occurs and for this exception an adapter is available that\n returns ``False`` on being called, the exception won't be reraised\n by the publisher. This happens only if ``handle_errors`` parameter\n of the ``publish()`` method is set to ``False``. Fixes problems when\n acting in a WSGI pipeline with a debugger middleware enabled.\n\n See https://bugs.launchpad.net/grok/+bug/332061 for details.\n\n- Fix #98471: Restrict redirects to current host. This causes a ValueError to\n be raised in the case of redirecting to a different host. If this is\n intentional, the parameter `trusted` can be given.\n\n- Move dependency on ``zope.testing`` from ``install_requires`` to\n ``tests_require``.\n\n- Remove ``time.sleep`` in the ``supportsRetry`` http request.\n\n- Add a fix for Internet Explorer versions which upload files with full\n filesystem paths as filenames.\n\n3.8.0 (2009-05-23)\n==================\n\n- Move ``IHTTPException``, ``IMethodNotAllowed``, and ``MethodNotAllowed``\n here from ``zope.app.http``, fixing dependency cycles involving\n ``zope.app.http``.\n\n- Move the ``DefaultViewName`` API here from ``zope.app.publisher.browser``,\n making it accessible to other packages that need it.\n\n3.7.0 (2009-05-13)\n==================\n\n- Move ``IView`` and ``IBrowserView`` interfaces into\n ``zope.browser.interfaces``, leaving BBB imports.\n\n3.6.4 (2009-04-26)\n==================\n\n- Add some BBB code to setDefaultSkin to allow IBrowserRequest's to continue\n to work without configuring any special adapter for IDefaultSkin.\n\n- Move `getDefaultSkin` to the skinnable module next to the `setDefaultSkin`\n method, leaving a BBB import in place. Mark `IDefaultBrowserLayer` as a\n `IBrowserSkinType` in code instead of relying on the ZCML to be loaded.\n\n3.6.3 (2009-03-18)\n==================\n\n- Mark HTTPRequest as IAttributeAnnotatable if ``zope.annotation`` is\n available, this was previously done by ``zope.app.i18n``.\n\n- Register `IHTTPRequest` -> `IUserPreferredCharsets` adapter in ZCML\n configuration. This was also previously done by ``zope.app.i18n``.\n\n3.6.2 (2009-03-14)\n==================\n\n- Add an adapter from ``zope.security.interfaces.IPrincipal`` to\n ``zope.publisher.interfaces.logginginfo.ILoggingInfo``. It was moved\n from ``zope.app.security`` as a part of refactoring process.\n\n- Add adapters from HTTP and FTP request to\n ``zope.authentication.ILoginPassword`` interface. They are moved from\n ``zope.app.security`` as a part of refactoring process. This change adds a\n dependency on the ``zope.authentication`` package, but it's okay, since it's\n a tiny contract definition-only package.\n\n See http://mail.zope.org/pipermail/zope-dev/2009-March/035325.html for\n reasoning.\n\n3.6.1 (2009-03-09)\n==================\n\n- Fix: remove IBrowserRequest dependency in http implementation based on\n condition for setDefaultSkin. Use ISkinnable instead of IBrowserRequest.\n\n3.6.0 (2009-03-08)\n==================\n\n- Clean-up: Move skin related code from zope.publisher.interfaces.browser and\n zope.publisher.browser to zope.publihser.interfaces and\n zope.publisher.skinnable and provide BBB imports. See skinnable.txt for more\n information.\n\n- Fix: ensure that we only apply skin interface in setDefaultSkin which also\n provide IBrowserSkinType. This will ensure that we find a skin if the\n applySkin method will lookup for a skin based on this type interface.\n\n- Fix: Make it possible to use adapters and not only interfaces as skins from\n the adapter registry. Right now the defaultSkin directive registers simple\n interfaces as skin adapters which will run into a TypeError if someone tries\n to adapter such a skin adapter. Probably we should change the defaultSkin\n directive and register real adapters instead of using the interfaces as fake\n adapters where we expect adapter factories.\n\n- Feature: allow use of ``applySkinof`` with different skin types using the\n optional ``skinType`` argument, which is by default set to\n ``IBrowserSkinType``.\n\n- Feature: implement the default skin pattern within adapters. This allows\n us to register default skins for other requests then only\n ``IBrowserRequest`` using ``IDefaultSkin`` adapters.\n\n Note, ``ISkinnable`` and ``ISkinType`` and the skin implementation should\n be moved out of the browser request modules. Packages like ``z3c.jsonrpc``\n do not depend on ``IBrowserRequest`` but they are skinnable.\n\n- Feature: add ``ISkinnable`` interface which allows us to implement the apply\n skin pattern not only for ``IBrowserRequest``.\n\n- Fix: Don't cause warnings on Python 2.6\n\n- Fix: Make ``IBrowserPage`` inherit ``IBrowserView``.\n\n- Move ``IView`` and ``IDefaultViewName`` here from\n ``zope.component.interfaces``. Stop inheriting from deprecated (for years)\n interfaces defined in ``zope.component``.\n\n- Remove deprecated code.\n\n- Clean-up: Move ``zope.testing`` from extras to dependencies, per Zope\n Framework policy. Remove ``zope.app.testing`` as a dependency: tests run\n fine without it.\n\n3.5.6 (2009-02-14)\n==================\n\n- Fix an untested code path that incorrectly attempted to construct a\n ``NotFound``, adding a test.\n\n\n3.5.5 (2009-02-04)\n==================\n\n- LP #322486: ``setStatus()`` now allows any ``int()``-able status value.\n\n\n3.5.4 (2008-09-22)\n==================\n\n\n- LP #98440: interfaces lost on retried request\n\n- LP #273296: dealing more nicely with malformed HTTP_ACCEPT_LANGUAGE headers\n within getPreferredLanguages().\n\n- LP #253362: dealing more nicely with malformed HTTP_ACCEPT_CHARSET headers\n within getPreferredCharsets().\n\n- LP #98284: Pass the ``size`` argument to readline, as the version of\n twisted used in zope.app.twisted supports it.\n\n- Fix the LP #98284 fix: do not pass ``size`` argument of None that causes\n cStringIO objects to barf with a TypeError.\n\n\n3.5.3 (2008-06-20)\n==================\n\n- It turns out that some Web servers (Paste for example) do not send the EOF\n character after the data has been transmitted and the read() of the cached\n stream simply hangs if no expected content length has been specified.\n\n\n3.5.2 (2008-04-06)\n==================\n\n- A previous fix to handle posting of non-form data broke handling of\n form data with extra information in the content type, as in::\n\n application/x-www-form-urlencoded; charset=UTF-8\n\n3.5.1 (2008-03-23)\n==================\n\n- When posting non-form (and non-multipart) data, the request body was\n consumed and discarded. This makes it impossible to deal with other\n post types, like xml-rpc or json without resorting to overly complex\n \"request factory\" contortions.\n\n- https://bugs.launchpad.net/zope2/+bug/143873\n\n ``zope.publisher.http.HTTPCharsets`` was confused by the Zope 2\n publisher, which gives misleading information about which headers\n it has.\n\n3.5.0 (2008-03-02)\n==================\n\n- Added a PasteDeploy app_factory implementation. This should make\n it easier to integrate Zope 3 applications with PasteDeploy. It\n also makes it easier to control the publication used, giving far\n greater control over application policies (e.g. whether or not to\n use the ZODB).\n\n3.4.2 (2007-12-07)\n==================\n\n- Made segmentation of URLs not strip (trailing) whitespace from path segments\n to allow URLs ending in %20 to be handled correctly. (#172742)\n\n3.4.1 (2007-09-29)\n==================\n\nNo changes since 3.4.1b2.\n\n3.4.1b2 (2007-08-02)\n====================\n\n- Add support for Python 2.5.\n\n- Fix a problem with ``request.get()`` when the object that's to be\n retrieved is the request itself.\n\n\n3.4.1b1 (2007-07-13)\n====================\n\nNo changes.\n\n\n3.4.0b2 (2007-07-05)\n====================\n\n- LP #122054: ``HTTPInputStream`` understands both the CONTENT_LENGTH and\n HTTP_CONTENT_LENGTH environment variables. It is also now tolerant\n of empty strings and will treat those as if the variable were\n absent.\n\n\n3.4.0b1 (2007-07-05)\n====================\n\n- Fix caching issue. The input stream never got cached in a temp file\n because of a wrong content-length header lookup. Added CONTENT_LENGTH\n header check in addition to the previous used HTTP_CONTENT_LENGTH. The\n ``HTTP_`` prefix is sometimes added by some CGI proxies, but CONTENT_LENGTH\n is the right header info for the size.\n\n- LP #98413: ``HTTPResponse.handleException`` should set the content type\n\n\n3.4.0a1 (2007-04-22)\n====================\n\nInitial release as a separate project, corresponds to zope.publisher\nfrom Zope 3.4.0a1\n",
