Next release
============
Bug Fixes
---------
- Pyramid did not properly generate static URLs using
``pyramid.url.static_url`` when passed a caller-package relative path due
to a refactoring.
Internal
--------
- Use ``config.with_package`` in view_config decorator rather than
manufacturing a new renderer helper (cleanup).
1.2a2 (2011-08-27)
==================
Bug Fixes
---------
- When a ``renderers=`` argument is not specified to the Configurator
constructor, eagerly register and commit the default renderer set. This
permits the overriding of the default renderers, which was broken in 1.2a1
without a commit directly after Configurator construction.
- Mako rendering exceptions had the wrong value for an error message.
- An include could not set a root factory successfully because the
Configurator constructor unconditionally registered one that would be
treated as if it were "the word of the user".
Features
--------
- A session factory can now be passed in using the dotted name syntax.
1.2a1 (2011-08-24)
==================
Features
--------
- The ``[pshell]`` section in an ini configuration file now treats a
``setup`` key as a dotted name that points to a callable that is passed the
bootstrap environment. It can mutate the environment as necessary for
great justice.
- A new configuration setting named ``pyramid.includes`` is now available.
It is described in the "Environment Variables and ``.ini`` Files Settings"
narrative documentation chapter.
- Added a ``route_prefix`` argument to the
``pyramid.config.Configurator.include`` method. This argument allows you
to compose URL dispatch applications together. See the section entitled
"Using a Route Prefix to Compose Applications" in the "URL Dispatch"
narrative documentation chapter.
- Added a ``pyramid.security.NO_PERMISSION_REQUIRED`` constant for use in
``permission=`` statements to view configuration. This constant has a
value of the string ``__no_permission_required__``. This string value was
previously referred to in documentation; now the documentation uses the
constant.
- Added a decorator-based way to configure a response adapter:
``pyramid.response.response_adapter``. This decorator has the same use as
``pyramid.config.Configurator.add_response_adapter`` but it's declarative.
- The ``pyramid.events.BeforeRender`` event now has an attribute named
``rendering_val``. This can be used to introspect the value returned by a
view in a BeforeRender subscriber.
- New configurator directive: ``pyramid.config.Configurator.add_tween``.
This directive adds a "tween". A "tween" is used to wrap the Pyramid
router's primary request handling function. This is a feature may be used
by Pyramid framework extensions, to provide, for example, view timing
support and as a convenient place to hang bookkeeping code.
Tweens are further described in the narrative docs section in the Hooks
chapter, named "Registering Tweens".
- New paster command ``paster ptweens``, which prints the current "tween"
configuration for an application. See the section entitled "Displaying
Tweens" in the Command-Line Pyramid chapter of the narrative documentation
for more info.
- The Pyramid debug logger now uses the standard logging configuration
(usually set up by Paste as part of startup). This means that output from
e.g. ``debug_notfound``, ``debug_authorization``, etc. will go to the
normal logging channels. The logger name of the debug logger will be the
package name of the *caller* of the Configurator's constructor.
- A new attribute is available on request objects: ``exc_info``. Its value
will be ``None`` until an exception is caught by the Pyramid router, after
which it will be the result of ``sys.exc_info()``.
- ``pyramid.testing.DummyRequest`` now implements the
``add_finished_callback`` and ``add_response_callback`` methods.
- New methods of the ``pyramid.config.Configurator`` class:
``set_authentication_policy`` and ``set_authorization_policy``. These are
meant to be consumed mostly by add-on authors.
- New Configurator method: ``set_root_factory``.
- Pyramid no longer eagerly commits some default configuration statements at
Configurator construction time, which permits values passed in as
constructor arguments (e.g. ``authentication_policy`` and
``authorization_policy``) to override the same settings obtained via an
"include".
- Better Mako rendering exceptions via
``pyramid.mako_templating.MakoRenderingException``
- New request methods: ``current_route_url``, ``current_route_path``, and
``static_path``.
- New functions in ``pyramid.url``: ``current_route_path`` and
``static_path``.
- The ``pyramid.request.Request.static_url`` API (and its brethren
``pyramid.request.Request.static_path``, ``pyramid.url.static_url``, and
``pyramid.url.static_path``) now accept an asbolute filename as a "path"
argument. This will generate a URL to an asset as long as the filename is
in a directory which was previously registered as a static view.
Previously, trying to generate a URL to an asset using an absolute file
path would raise a ValueError.
- The ``RemoteUserAuthenticationPolicy ``, ``AuthTktAuthenticationPolicy``,
and ``SessionAuthenticationPolicy`` constructors now accept an additional
keyword argument named ``debug``. By default, this keyword argument is
``False``. When it is ``True``, debug information will be sent to the
Pyramid debug logger (usually on stderr) when the ``authenticated_userid``
or ``effective_principals`` method is called on any of these policies. The
output produced can be useful when trying to diagnose
authentication-related problems.
- New view predicate: ``match_param``. Example: a view added via
``config.add_view(aview, match_param='action=edit')`` will be called only
when the ``request.matchdict`` has a value inside it named ``action`` with
a value of ``edit``.
Internal
--------
- The Pyramid "exception view" machinery is now implemented as a "tween"
(``pyramid.tweens.excview_tween_factory``).
- WSGIHTTPException (HTTPFound, HTTPNotFound, etc) now has a new API named
"prepare" which renders the body and content type when it is provided with
a WSGI environ. Required for debug toolbar.
- Once ``__call__`` or ``prepare`` is called on a WSGIHTTPException, the body
will be set, and subsequent calls to ``__call__`` will always return the
same body. Delete the body attribute to rerender the exception body.
- Previously the ``pyramid.events.BeforeRender`` event *wrapped* a dictionary
(it addressed it as its ``_system`` attribute). Now it *is* a dictionary
(it inherits from ``dict``), and it's the value that is passed to templates
as a top-level dictionary.
- The ``route_url``, ``route_path``, ``resource_url``, ``static_url``, and
``current_route_url`` functions in the ``pyramid.url`` package now delegate
to a method on the request they've been passed, instead of the other way
around. The pyramid.request.Request object now inherits from a mixin named
pyramid.url.URLMethodsMixin to make this possible, and all url/path
generation logic is embedded in this mixin.
- Refactor ``pyramid.config`` into a package.
- Removed the ``_set_security_policies`` method of the Configurator.
- Moved the ``StaticURLInfo`` class from ``pyramid.static`` to
``pyramid.config.views``.
- Move the ``Settings`` class from ``pyramid.settings`` to
``pyramid.config.settings``.
- Move the ``OverrideProvider``, ``PackageOverrides``, ``DirectoryOverride``,
and ``FileOverride`` classes from ``pyramid.asset`` to
``pyramid.config.assets``.
Deprecations
------------
- All Pyramid-related deployment settings (e.g. ``debug_all``,
``debug_notfound``) are now meant to be prefixed with the prefix
``pyramid.``. For example: ``debug_all`` -> ``pyramid.debug_all``. The
old non-prefixed settings will continue to work indefinitely but supplying
them may eventually print a deprecation warning. All scaffolds and
tutorials have been changed to use prefixed settings.
- The ``settings`` dictionary now raises a deprecation warning when you
attempt to access its values via ``__getattr__`` instead of
via ``__getitem__``.
Backwards Incompatibilities
---------------------------
- If a string is passed as the ``debug_logger`` parameter to a Configurator,
that string is considered to be the name of a global Python logger rather
than a dotted name to an instance of a logger.
- The ``pyramid.config.Configurator.include`` method now accepts only a
single ``callable`` argument (a sequence of callables used to be
permitted). If you are passing more than one ``callable`` to
``pyramid.config.Configurator.include``, it will break. You now must now
instead make a separate call to the method for each callable. This change
was introduced to support the ``route_prefix`` feature of include.
- It may be necessary to more strictly order configuration route and view
statements when using an "autocommitting" Configurator. In the past, it
was possible to add a view which named a route name before adding a route
with that name when you used an autocommitting configurator. For example::
config = Configurator(autocommit=True)
config.add_view('my.pkg.someview', route_name='foo')
config.add_route('foo', '/foo')
The above will raise an exception when the view attempts to add itself.
Now you must add the route before adding the view::
config = Configurator(autocommit=True)
config.add_route('foo', '/foo')
config.add_view('my.pkg.someview', route_name='foo')
This won't effect "normal" users, only people who have legacy BFG codebases
that used an autommitting configurator and possibly tests that use the
configurator API (the configurator returned by ``pyramid.testing.setUp`` is
an autocommitting configurator). The right way to get around this is to
use a non-autocommitting configurator (the default), which does not have
these directive ordering requirements.
- The ``pyramid.config.Configurator.add_route`` directive no longer returns a
route object. This change was required to make route vs. view
configuration processing work properly.
Documentation
-------------
- Narrative and API documentation which used the ``route_url``,
``route_path``, ``resource_url``, ``static_url``, and ``current_route_url``
functions in the ``pyramid.url`` package have now been changed to use
eponymous methods of the request instead.
- Added a section entitled "Using a Route Prefix to Compose Applications" to
the "URL Dispatch" narrative documentation chapter.
- Added a new module to the API docs: ``pyramid.tweens``.
- Added a "Registering Tweens" section to the "Hooks" narrative chapter.
- Added a "Displaying Tweens" section to the "Command-Line Pyramid" narrative
chapter.
- Added documentation for the ``pyramid.tweens`` and ``pyramid.includes``
configuration settings to the "Environment Variables and ``.ini`` Files
Settings" chapter.
- Added a Logging chapter to the narrative docs (based on the Pylons logging
docs, thanks Phil).
- Added a Paste chapter to the narrative docs (moved content from the Project
chapter).
- Added the ``pyramid.interfaces.IDict`` interface representing the methods
of a dictionary, for documentation purposes only (IMultiDict and
IBeforeRender inherit from it).
- All tutorials now use - The ``route_url``, ``route_path``,
``resource_url``, ``static_url``, and ``current_route_url`` methods of the
request rather than the function variants imported from ``pyramid.url``.
- The ZODB wiki tutorial now uses the ``pyramid_zodbconn`` package rather
than the ``repoze.zodbconn`` package to provide ZODB integration.
Dependency Changes
------------------
- Pyramid now relies on PasteScript >= 1.7.4. This version contains a
feature important for allowing flexible logging configuration.
Scaffolds
----------
- All scaffolds now use the ``pyramid_tm`` package rather than the
``repoze.tm2`` middleware to manage transaction management.
- The ZODB scaffold now uses the ``pyramid_zodbconn`` package rather than the
``repoze.zodbconn`` package to provide ZODB integration.
- All scaffolds now use the ``pyramid_debugtoolbar`` package rather than the
``WebError`` package to provide interactive debugging features.
- Projects created via a scaffold no longer depend on the ``WebError``
package at all; configuration in the ``production.ini`` file which used to
require its ``error_catcher`` middleware has been removed. Configuring
error catching / email sending is now the domain of the ``pyramid_exclog``
package (see https://docs.pylonsproject.org/projects/pyramid_exclog/dev/).
Bug Fixes
---------
- Fixed an issue with the default renderer not working at certain times. See
https://github.com/Pylons/pyramid/issues/249
