==========
Features
--------
- Add support for Python 3.8.
See https://github.com/Pylons/pyramid/pull/3547
- Changed the default ``serializer`` on
``pyramid.session.SignedCookieSessionFactory`` to use
``pyramid.session.JSONSerializer`` instead of
``pyramid.session.PickleSerializer``. Read
"Changes to ISession in Pyramid 2.0" in the "Sessions" chapter of the
documentation for more information about why this change was made.
See https://github.com/Pylons/pyramid/pull/3413
- It is now possible to control whether a route pattern contains a trailing
slash when it is composed with a route prefix using
``config.include(..., route_prefix=...)`` or
``with config.route_prefix_context(...)``. This can be done by specifying
an empty pattern and setting the new argument
``inherit_slash=True``. For example:
.. code-block:: python
with config.route_prefix_context('/users'):
config.add_route('users', '', inherit_slash=True)
In the example, the resulting pattern will be ``/users``. Similarly, if the
route prefix were ``/users/`` then the final pattern would be ``/users/``.
If the ``pattern`` was ``'/'``, then the final pattern would always be
``/users/``. This new setting is only available if the pattern supplied
to ``add_route`` is the empty string (``''``).
See https://github.com/Pylons/pyramid/pull/3420
- No longer define ``pyramid.request.Request.json_body`` which is already
provided by WebOb. This allows the attribute to now be settable.
See https://github.com/Pylons/pyramid/pull/3447
- Improve debugging info from ``pyramid.view.view_config`` decorator.
See https://github.com/Pylons/pyramid/pull/3483
- A new parameter, ``allow_no_origin``, was added to
``pyramid.config.Configurator.set_default_csrf_options`` as well as
``pyramid.csrf.check_csrf_origin``. This option controls whether a
request is rejected if it has no ``Origin`` or ``Referer`` header -
often the result of a user configuring their browser not to send a
``Referer`` header for privacy reasons even on same-domain requests.
The default is to reject requests without a known origin. It is also
possible to allow the special ``Origin: null`` header by adding it to the
``pyramid.csrf_trusted_origins`` list in the settings.
See https://github.com/Pylons/pyramid/pull/3512
and https://github.com/Pylons/pyramid/pull/3518
- A new parameter, ``check_origin``, was added to
``pyramid.config.Configurator.set_default_csrf_options`` which disables
origin checking entirely.
See https://github.com/Pylons/pyramid/pull/3518
- Added ``pyramid.interfaces.IPredicateInfo`` which defines the object passed
to predicate factories as their second argument.
See https://github.com/Pylons/pyramid/pull/3514
- Added support for serving pre-compressed static assets by using the
``content_encodings`` argument of
``pyramid.config.Configurator.add_static_view`` and
``pyramid.static.static_view``.
See https://github.com/Pylons/pyramid/pull/3537
- Fix ``DeprecationWarning`` emitted by using the ``imp`` module.
See https://github.com/Pylons/pyramid/pull/3553
- Properties created via ``config.add_request_method(..., property=True)`` or
``request.set_property`` used to be readonly. They can now be overridden
via ``request.foo = ...`` and until the value is deleted it will return
the overridden value. This is most useful when mocking request properties
in testing.
See https://github.com/Pylons/pyramid/pull/3559
Deprecations
------------
- Deprecated ``pyramid.session.PickleSerializer``.
See https://github.com/pylons/pyramid/issues/2709
and https://github.com/pylons/pyramid/pull/3353
and https://github.com/pylons/pyramid/pull/3413
Backward Incompatibilities
--------------------------
- Drop support for Python 2.7.
- Drop support for Python 3.4.
See https://github.com/Pylons/pyramid/pull/3547
- ``pcreate`` and the builtin scaffolds have been removed in favor of
using the ``cookiecutter`` tool and the ``pyramid-cookiecutter-starter``
cookiecutter. The script and scaffolds were deprecated in Pyramid 1.8.
See https://github.com/Pylons/pyramid/pull/3406
- Removed ``pyramid.interfaces.ITemplateRenderer``. This interface was
deprecated since Pyramid 1.5 and was an interface
used by libraries like ``pyramid_mako`` and ``pyramid_chameleon`` but
provided no functionality within Pyramid itself.
See https://github.com/Pylons/pyramid/pull/3409
- Removed ``pyramid.security.has_permission``,
``pyramid.security.authenticated_userid``,
``pyramid.security.unauthenticated_userid``, and
``pyramid.security.effective_principals``. These methods were deprecated
in Pyramid 1.5 and all have equivalents available as properties on the
request. For example, ``request.authenticated_userid``.
See https://github.com/Pylons/pyramid/pull/3410
- Removed support for supplying a media range to the ``accept`` predicate of
both ``pyramid.config.Configurator.add_view`` and
``pyramid.config.Configurator.add_route``. These options were deprecated
in Pyramid 1.10 and WebOb 1.8 because they resulted in uncontrollable
matching that was not compliant with the RFC.
See https://github.com/Pylons/pyramid/pull/3411
- Removed ``pyramid.session.UnencryptedCookieSessionFactoryConfig``. This
session factory was replaced with
``pyramid.session.SignedCookieSessionFactory`` in Pyramid 1.5 and has been
deprecated since then.
See https://github.com/Pylons/pyramid/pull/3412
- Removed ``pyramid.session.signed_serialize``, and
``pyramid.session.signed_deserialize``. These methods were only used by
the now-removed ``pyramid.session.UnencryptedCookieSessionFactoryConfig``
and were coupled to the vulnerable pickle serialization format which could
lead to remove code execution if the secret key is compromised.
See https://github.com/Pylons/pyramid/pull/3412
- Changed the default ``serializer`` on
``pyramid.session.SignedCookieSessionFactory`` to use
``pyramid.session.JSONSerializer`` instead of
``pyramid.session.PickleSerializer``. Read
"Changes to ISession in Pyramid 2.0" in the "Sessions" chapter of the
documentation for more information about why this change was made.
See https://github.com/Pylons/pyramid/pull/3413
- ``pyramid.request.Request.invoke_exception_view`` will no longer be called
by the default execution policy.
See https://github.com/Pylons/pyramid/pull/3496
- ``pyramid.config.Configurator.scan`` will no longer, by default, execute
Venusian decorator callbacks registered for categories other than
``'pyramid'``. To find any decorator regardless of category, specify
``config.scan(..., categories=None)``.
See https://github.com/Pylons/pyramid/pull/3510
- The second argument to predicate factories has been changed from ``config``
to ``info``, an instance of ``pyramid.interfaces.IPredicateInfo``. This
limits the data available to predicates but still provides the package,
registry, settings and dotted-name resolver which should cover most use
cases and is largely backward compatible.
See https://github.com/Pylons/pyramid/pull/3514
- Removed the ``check_csrf`` predicate. Instead, use
``pyramid.config.Configurator.set_default_csrf_options`` and the
``require_csrf`` view option to enable automatic CSRF checking.
See https://github.com/Pylons/pyramid/pull/3521
Documentation Changes
