Description: ``zope.interface`` README
=========================
This package is intended to be independently reusable in any Python
project. It is maintained by the `Zope Toolkit project
`_.
This package provides an implementation of "object interfaces" for Python.
Interfaces are a mechanism for labeling objects as conforming to a given
API or contract. So, this package can be considered as implementation of
the `Design By Contract`_ methodology support in Python.
.. _Design By Contract: http://en.wikipedia.org/wiki/Design_by_contract
For detailed documentation, please see http://docs.zope.org/zope.interface
``zope.interface Changelog``
============================
4.1.0 (2014-02-05)
------------------
- Updated ``boostrap.py`` to version 2.2.
- Added ``@named(name)`` declaration, that specifies the component name, so it
does not have to be passed in during registration.
4.0.5 (2013-02-28)
------------------
- Fixed a bug where a decorated method caused false positive failures on
``verifyClass()``.
4.0.4 (2013-02-21)
------------------
- Fixed a bug that was revealed by porting zope.traversing. During a loop, the
loop body modified a weakref dict causing a ``RuntimeError`` error.
4.0.3 (2012-12-31)
------------------
- Fleshed out PyPI Trove classifiers.
4.0.2 (2012-11-21)
------------------
- Added support for Python 3.3.
- Restored ability to install the package in the absence of ``setuptools``.
- LP #1055223: Fix test which depended on dictionary order and failed randomly
in Python 3.3.
4.0.1 (2012-05-22)
------------------
- Dropped explicit ``DeprecationWarnings`` for "class advice" APIS (these
APIs are still deprecated under Python 2.x, and still raise an exception
under Python 3.x, but no longer cause a warning to be emitted under
Python 2.x).
4.0.0 (2012-05-16)
------------------
- Automated build of Sphinx HTML docs and running doctest snippets via tox.
- Deprecated the "class advice" APIs from ``zope.interface.declarations``:
``implements``, ``implementsOnly``, and ``classProvides``. In their place,
prefer the equivalent class decorators: ``@implementer``,
``@implementer_only``, and ``@provider``. Code which uses the deprecated
APIs will not work as expected under Py3k.
- Removed use of '2to3' and associated fixers when installing under Py3k.
The code is now in a "compatible subset" which supports Python 2.6, 2.7,
and 3.2, including PyPy 1.8 (the version compatible with the 2.7 language
spec).
- Dropped explicit support for Python 2.4 / 2.5 / 3.1.
- Added support for PyPy.
- Added support for continuous integration using ``tox`` and ``jenkins``.
- Added 'setup.py dev' alias (runs ``setup.py develop`` plus installs
``nose`` and ``coverage``).
- Added 'setup.py docs' alias (installs ``Sphinx`` and dependencies).
- Replaced all unittest coverage previously accomplished via doctests with
unittests. The doctests have been moved into a ``docs`` section, managed
as a Sphinx collection.
- LP #910987: Ensure that the semantics of the ``lookup`` method of
``zope.interface.adapter.LookupBase`` are the same in both the C and
Python implementations.
- LP #900906: Avoid exceptions due to tne new ``__qualname__`` attribute
added in Python 3.3 (see PEP 3155 for rationale). Thanks to Antoine
Pitrou for the patch.
3.8.0 (2011-09-22)
------------------
- New module ``zope.interface.registry``. This is code moved from
``zope.component.registry`` which implements a basic nonperistent component
registry as ``zope.interface.registry.Components``. This class was moved
from ``zope.component`` to make porting systems (such as Pyramid) that rely
only on a basic component registry to Python 3 possible without needing to
port the entirety of the ``zope.component`` package. Backwards
compatibility import shims have been left behind in ``zope.component``, so
this change will not break any existing code.
- New ``tests_require`` dependency: ``zope.event`` to test events sent by
Components implementation. The ``zope.interface`` package does not have a
hard dependency on ``zope.event``, but if ``zope.event`` is importable, it
will send component registration events when methods of an instance of
``zope.interface.registry.Components`` are called.
- New interfaces added to support ``zope.interface.registry.Components``
addition: ``ComponentLookupError``, ``Invalid``, ``IObjectEvent``,
``ObjectEvent``, ``IComponentLookup``, ``IRegistration``,
``IUtilityRegistration``, ``IAdapterRegistration``,
``ISubscriptionAdapterRegistration``, ``IHandlerRegistration``,
``IRegistrationEvent``, ``RegistrationEvent``, ``IRegistered``,
``Registered``, ``IUnregistered``, ``Unregistered``,
``IComponentRegistry``, and ``IComponents``.
- No longer Python 2.4 compatible (tested under 2.5, 2.6, 2.7, and 3.2).
3.7.0 (2011-08-13)
------------------
- Move changes from 3.6.2 - 3.6.5 to a new 3.7.x release line.
3.6.7 (2011-08-20)
------------------
- Fix sporadic failures on x86-64 platforms in tests of rich comparisons
of interfaces.
3.6.6 (2011-08-13)
------------------
- LP #570942: Now correctly compare interfaces from different modules but
with the same names.
N.B.: This is a less intrusive / destabilizing fix than the one applied in
3.6.3: we only fix the underlying cmp-alike function, rather than adding
the other "rich comparison" functions.
- Revert to software as released with 3.6.1 for "stable" 3.6 release branch.
3.6.5 (2011-08-11)
------------------
- LP #811792: work around buggy behavior in some subclasses of
``zope.interface.interface.InterfaceClass``, which invoke ``__hash__``
before initializing ``__module__`` and ``__name__``. The workaround
returns a fixed constant hash in such cases, and issues a ``UserWarning``.
- LP #804832: Under PyPy, ``zope.interface`` should not build its C
extension. Also, prevent attempting to build it under Jython.
- Add a tox.ini for easier xplatform testing.
- Fix testing deprecation warnings issued when tested under Py3K.
3.6.4 (2011-07-04)
------------------
- LP 804951: InterfaceClass instances were unhashable under Python 3.x.
3.6.3 (2011-05-26)
------------------
- LP #570942: Now correctly compare interfaces from different modules but
with the same names.
3.6.2 (2011-05-17)
------------------
- Moved detailed documentation out-of-line from PyPI page, linking instead to
http://docs.zope.org/zope.interface .
- Fixes for small issues when running tests under Python 3.2 using
``zope.testrunner``.
- LP # 675064: Specify return value type for C optimizations module init
under Python 3: undeclared value caused warnings, and segfaults on some
64 bit architectures.
- setup.py now raises RuntimeError if you don't have Distutils installed when
running under Python 3.
3.6.1 (2010-05-03)
------------------
- A non-ASCII character in the changelog made 3.6.0 uninstallable on
Python 3 systems with another default encoding than UTF-8.
- Fixed compiler warnings under GCC 4.3.3.
3.6.0 (2010-04-29)
------------------
- LP #185974: Clear the cache used by ``Specificaton.get`` inside
``Specification.changed``. Thanks to Jacob Holm for the patch.
- Added support for Python 3.1. Contributors:
Lennart Regebro
Martin v Loewis
Thomas Lotze
Wolfgang Schnerring
The 3.1 support is completely backwards compatible. However, the implements
syntax used under Python 2.X does not work under 3.X, since it depends on
how metaclasses are implemented and this has changed. Instead it now supports
a decorator syntax (also under Python 2.X)::
class Foo:
implements(IFoo)
...
can now also be written::
@implementer(IFoo):
class Foo:
...
There are 2to3 fixers available to do this change automatically in the
zope.fixers package.
- Python 2.3 is no longer supported.
3.5.4 (2009-12-23)
------------------
- Use the standard Python doctest module instead of zope.testing.doctest, which
has been deprecated.
3.5.3 (2009-12-08)
------------------
- Fix an edge case: make providedBy() work when a class has '__provides__' in
its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490)
3.5.2 (2009-07-01)
------------------
- BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of
the data structures when something is removed. This avoids leaving
references to global objects (interfaces) that may be slated for
removal from the calling application.
3.5.1 (2009-03-18)
------------------
- verifyObject: use getattr instead of hasattr to test for object attributes
in order to let exceptions other than AttributeError raised by properties
propagate to the caller
- Add Sphinx-based documentation building to the package buildout
configuration. Use the ``bin/docs`` command after buildout.
- Improve package description a bit. Unify changelog entries formatting.
- Change package's mailing list address to zope-dev at zope.org as
zope3-dev at zope.org is now retired.
3.5.0 (2008-10-26)
------------------
- Fixed declaration of _zope_interface_coptimizations, it's not a top level
package.
- Add a DocTestSuite for odd.py module, so their tests are run.
- Allow to bootstrap on Jython.
- Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification
was missing a declaration for __iro__.
- Added optional code optimizations support, which allows the building
of C code optimizations to fail (Jython).
- Replaced `_flatten` with a non-recursive implementation, effectively making
it 3x faster.
3.4.1 (2007-10-02)
------------------
- Fixed a setup bug that prevented installation from source on systems
without setuptools.
3.4.0 (2007-07-19)
------------------
- Final release for 3.4.0.
3.4.0b3 (2007-05-22)
--------------------
- Objects with picky custom comparison methods couldn't be added to
component registries. Now, when checking whether an object is
already registered, identity comparison is used.
3.3.0.1 (2007-01-03)
--------------------
- Made a reference to OverflowWarning, which disappeared in Python
2.5, conditional.
3.3.0 (2007/01/03)
------------------
New Features
++++++++++++
- The adapter-lookup algorithim was refactored to make it
much simpler and faster.
Also, more of the adapter-lookup logic is implemented in C, making
debugging of application code easier, since there is less
infrastructre code to step through.
- We now treat objects without interface declarations as if they
declared that they provide zope.interface.Interface.
- There are a number of richer new adapter-registration interfaces
that provide greater control and introspection.
- Added a new interface decorator to zope.interface that allows the
setting of tagged values on an interface at definition time (see
zope.interface.taggedValue).
Bug Fixes
+++++++++
- A bug in multi-adapter lookup sometimes caused incorrect adapters to
be returned.
3.2.0.2 (2006-04-15)
--------------------
- Fix packaging bug: 'package_dir' must be a *relative* path.
3.2.0.1 (2006-04-14)
--------------------
- Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds.
3.2.0 (2006-01-05)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope 3.2.0 release.
3.1.0 (2005-10-03)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope 3.1.0 release.
- Made attribute resolution order consistent with component lookup order,
i.e. new-style class MRO semantics.
- Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in
favor of 'implementedBy' and 'providedBy'.
3.0.1 (2005-07-27)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope X3.0.1 release.
- Fixed a bug reported by James Knight, which caused adapter registries
to fail occasionally to reflect declaration changes.
3.0.0 (2004-11-07)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope X3.0.0 release.

An interface specification is used to track interface declarations
and component registrations.
This class is a base class for both interfaces themselves and for
interface specifications (declarations).
Specifications are mutable. If you reassign their bases, their
relations with other specifications are adjusted accordingly.

TODO: It would ne nice if:
More specific interfaces should sort before less specific ones.
Otherwise, sort on name and module.
But this is too complicated, and we're going to punt on it
for now.
For now, sort on interface and module name.
None is treated as a pseudo interface that implies the loosest
contact possible, no contract. For that reason, all interfaces
sort before None.

"""Interfaces
This package implements the Python "scarecrow" proposal.
The package exports two objects, `Interface` and `Attribute` directly. It also
exports several helper methods. Interface is used to create an interface with
a class statement, as in:
class IMyInterface(Interface):
'''Interface documentation
'''
def meth(arg1, arg2):
'''Documentation for meth
'''
# Note that there is no self argument
To find out what you can do with interfaces, see the interface
interface, `IInterface` in the `interfaces` module.
The package has several public modules:
o `declarations` provides utilities to declare interfaces on objects. It
also provides a wide range of helpful utilities that aid in managing
declared interfaces. Most of its public names are however imported here.
o `document` has a utility for documenting an interface as structured text.
o `exceptions` has the interface-defined exceptions
o `interfaces` contains a list of all public interfaces for this package.
o `verify` has utilities for verifying implementations of interfaces.
See the module doc strings for more information.

This package implements the Python "scarecrow" proposal.
The package exports two objects, `Interface` and `Attribute` directly. It also
exports several helper methods. Interface is used to create an interface with
a class statement, as in:
class IMyInterface(Interface):
'''Interface documentation
'''
def meth(arg1, arg2):
'''Documentation for meth
'''
# Note that there is no self argument
To find out what you can do with interfaces, see the interface
interface, `IInterface` in the `interfaces` module.
The package has several public modules:
o `declarations` provides utilities to declare interfaces on objects. It
also provides a wide range of helpful utilities that aid in managing
declared interfaces. Most of its public names are however imported here.
o `document` has a utility for documenting an interface as structured text.
o `exceptions` has the interface-defined exceptions
o `interfaces` contains a list of all public interfaces for this package.
o `verify` has utilities for verifying implementations of interfaces.
See the module doc strings for more information.

This module was adapted from 'protocols.advice', part of the Python
Enterprise Application Kit (PEAK). Please notify the PEAK authors
(pje@telecommunity.com and tsarna@sarna.org) if bugs are found or
Zope-specific changes are required, so that the PEAK version of this module
can be kept in sync.
PEAK is a Python application framework that interoperates with (but does
not require) Zope 3 and Twisted. It provides tools for manipulating UML
models, object-relational persistence, aspect-oriented programming, and more.
Visit the PEAK home page at http://peak.telecommunity.com for more information.

(pje@telecommunity.com and tsarna@sarna.org) if bugs are found or
Zope-specific changes are required, so that the PEAK version of this module
can be kept in sync.
PEAK is a Python application framework that interoperates with (but does
not require) Zope 3 and Twisted. It provides tools for manipulating UML
models, object-relational persistence, aspect-oriented programming, and more.
Visit the PEAK home page at http://peak.telecommunity.com for more information.

This module was adapted from 'protocols.tests.advice', part of the Python
Enterprise Application Kit (PEAK). Please notify the PEAK authors
(pje@telecommunity.com and tsarna@sarna.org) if bugs are found or
Zope-specific changes are required, so that the PEAK version of this module

sE Interface objects
Interface objects describe the behavior of an object by containing
useful information about the object. This information includes:
o Prose documentation about the object. In Python terms, this
is called the "doc string" of the interface. In this element,
you describe how the object works in prose language and any
other useful information about the object.
o Descriptions of attributes. Attribute descriptions include
the name of the attribute and prose documentation describing
the attributes usage.
o Descriptions of methods. Method descriptions can include:
- Prose "doc string" documentation about the method and its
usage.
- A description of the methods arguments; how many arguments
are expected, optional arguments and their default values,
the position or arguments in the signature, whether the
method accepts arbitrary arguments and whether the method
accepts arbitrary keyword arguments.
o Optional tagged data. Interface objects (and their attributes and
methods) can have optional, application specific tagged data
associated with them. Examples uses for this are examples,
security assertions, pre/post conditions, and other possible
information you may want to associate with an Interface or its
attributes.
Not all of this information is mandatory. For example, you may
only want the methods of your interface to have prose
documentation and not describe the arguments of the method in
exact detail. Interface objects are flexible and let you give or
take any of these components.
Interfaces are created with the Python class statement using
either Interface.Interface or another interface, as in::
from zope.interface import Interface
class IMyInterface(Interface):
'''Interface documentation'''
def meth(arg1, arg2):
'''Documentation for meth'''
# Note that there is no self argument
class IMySubInterface(IMyInterface):
'''Interface documentation'''
def meth2():
'''Documentation for meth2'''
You use interfaces in two ways:
o You assert that your object implement the interfaces.
There are several ways that you can assert that an object
implements an interface:
1. Call zope.interface.implements in your class definition.
2. Call zope.interfaces.directlyProvides on your object.
3. Call 'zope.interface.classImplements' to assert that instances
of a class implement an interface.
For example::
from zope.interface import classImplements
classImplements(some_class, some_interface)
This approach is useful when it is not an option to modify
the class source. Note that this doesn't affect what the
class itself implements, but only what its instances
implement.
o You query interface meta-data. See the IInterface methods and
attributes for details.
c C s d S( se Get the interface attribute names

The functions defined in this interface are used to declare the
interfaces that objects provide and to query the interfaces that have
been declared.
Interfaces can be declared for objects in two ways:
- Interfaces are declared for instances of the object's class
- Interfaces are declared for the object directly.
The interfaces declared for an object are, therefore, the union of
interfaces declared for the object directly and the interfaces
declared for instances of the object's class.
Note that we say that a class implements the interfaces provided
by it's instances. An instance can also provide interfaces
directly. The interfaces provided by an object are the union of
the interfaces provided directly and the interfaces implemented by
the class.
c C s d S( s Return the interfaces provided by an object
This is the union of the interfaces directly provided by an
object and interfaces implemented by it's class.
The value returned is an IDeclaration.
N( ( t ob( ( s? /usr/lib64/python2.7/site-packages/zope/interface/interfaces.pyR s c C s d S( sq Return the interfaces implemented for a class' instances

The arguments after the class are one or more interfaces or
interface specifications (IDeclaration objects).
The interfaces given (including the interfaces in the
specifications) are added to any interfaces previously
declared.
Consider the following example::
class C(A, B):
...

Instances of ``C`` provide ``I1``, ``I2``, and whatever interfaces
instances of ``A`` and ``B`` provide.

Consider the following example::

The arguments after the object are one or more interfaces or

The interfaces given (including the interfaces in the

declared for the object.
Consider the following example::
class C(A, B):
...
ob = C()
directlyProvides(ob, I1, I2)
The object, ``ob`` provides ``I1``, ``I2``, and whatever interfaces
instances have been declared for instances of ``C``.
To remove directly provided interfaces, use ``directlyProvidedBy`` and
subtract the unwanted interfaces. For example::
directlyProvides(ob, directlyProvidedBy(ob)-I2)
removes I2 from the interfaces directly provided by
``ob``. The object, ``ob`` no longer directly provides ``I2``,
although it might still provide ``I2`` if it's class
implements ``I2``.
To add directly provided interfaces, use ``directlyProvidedBy`` and
include additional interfaces. For example::
directlyProvides(ob, directlyProvidedBy(ob), I2)
adds I2 to the interfaces directly provided by ob.

"""Implementation of interface declarations
There are three flavors of declarations:
- Declarations are used to simply name declared interfaces.
- ImplementsDeclarations are used to express the interfaces that a
class implements (that instances of the class provides).
Implements specifications support inheriting interfaces.
- ProvidesDeclarations are used to express interfaces directly
provided by objects.

There are three flavors of declarations:

- ImplementsDeclarations are used to express the interfaces that a
class implements (that instances of the class provides).
Implements specifications support inheriting interfaces.
- ProvidesDeclarations are used to express interfaces directly
provided by objects.

This function is designed to be called by an "advising" function executed
in a class suite. The "advising" function supplies a callback that it
wishes to have executed when the containing class is created. The
callback will be given one argument: the newly created containing class.
The return value of the callback will be used in place of the class, so
the callback should return the input if it does not wish to replace the
class.
The optional 'depth' argument to this function determines the number of
frames between this function and the targeted class suite. 'depth'
defaults to 2, since this skips this function's frame and one calling
function frame. If you use this function from a function called directly
in the class suite, the default will be correct, otherwise you will need
to determine the correct depth yourself.
This function works by installing a special class factory function in
place of the '__metaclass__' of the containing class. Therefore, only
callbacks *after* the last '__metaclass__' assignment in the containing
class will be executed. Be sure that classes using "advising" functions
declare any '__metaclass__' *first*, to ensure all callbacks are run."""

The ISO calendar is a widely used variant of the Gregorian calendar.
See http://www.phys.uu.nl/~vgent/calendar/isocalendar.htm for a good
explanation.
The ISO year consists of 52 or 53 full weeks, and where a week starts
on a Monday and ends on a Sunday. The first week of an ISO year is the
first (Gregorian) calendar week of a year containing a Thursday. This
is called week number 1, and the ISO year of that Thursday is the same
as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year
2004 begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004, so
that date(2003, 12, 29).isocalendar() == (2004, 1, 1) and
date(2004, 1, 4).isocalendar() == (2004, 1, 7).

This is 'YYYY-MM-DD'.
For example, date(2002, 12, 4).isoformat() == '2002-12-04'.
N( ( ( ( sE /usr/lib64/python2.7/site-packages/zope/interface/common/idatetime.pyt isoformat s c C s d S( s4 For a date d, str(d) is equivalent to d.isoformat().N( ( ( ( sE /usr/lib64/python2.7/site-packages/zope/interface/common/idatetime.pyt __str__ s c C s d S( sp Return a string representing the date.
For example date(2002, 12, 4).ctime() == 'Wed Dec 4 00:00:00 2002'.
d.ctime() is equivalent to time.ctime(time.mktime(d.timetuple()))
on platforms where the native C ctime() function
(which time.ctime() invokes, but which date.ctime() does not invoke)
conforms to the C standard.

If optional argument tz is None or not specified, this is like today(),
but, if possible, supplies more precision than can be gotten from going
through a time.time() timestamp (for example, this may be possible on
platforms supplying the C gettimeofday() function).
Else tz must be an instance of a class tzinfo subclass, and the current
date and time are converted to tz's time zone. In this case the result
is equivalent to tz.fromutc(datetime.utcnow().replace(tzinfo=tz)).
See also today(), utcnow().
N( ( t tz( ( sE /usr/lib64/python2.7/site-packages/zope/interface/common/idatetime.pyt now s c C s d S( s Return the current UTC date and time, with tzinfo None.

naive datetime object.

Same as is returned by time.time(). If optional argument tz is None or
not specified, the timestamp is converted to the platform's local date
and time, and the returned datetime object is naive.
Else tz must be an instance of a class tzinfo subclass, and the
timestamp is converted to tz's time zone. In this case the result is
equivalent to
tz.fromutc(datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz)).
fromtimestamp() may raise ValueError, if the timestamp is out of the
range of values supported by the platform C localtime() or gmtime()
functions. It's common for this to be restricted to years in 1970
through 2038. Note that on non-POSIX systems that include leap seconds
in their notion of a timestamp, leap seconds are ignored by
fromtimestamp(), and then it's possible to have two timestamps
differing by a second that yield identical datetime objects.

date and time members so the result is the same UTC time as self, but
in tz's local time.
tz must be an instance of a tzinfo subclass, and its utcoffset() and
dst() methods must not return None. self must be aware (self.tzinfo
must not be None, and self.utcoffset() must not return None).
If self.tzinfo is tz, self.astimezone(tz) is equal to self: no
adjustment of date or time members is performed. Else the result is
local time in time zone tz, representing the same UTC time as self:
after astz = dt.astimezone(tz), astz - astz.utcoffset()
will usually have the same date and time members as dt - dt.utcoffset().
The discussion of class tzinfo explains the cases at Daylight Saving
Time transition boundaries where this cannot be achieved (an issue only
if tz models both standard and daylight time).
If you merely want to attach a time zone object tz to a datetime dt
without adjustment of date and time members, use dt.replace(tzinfo=tz).
If you merely want to remove the time zone object from an aware
datetime dt without conversion of date and time members, use
dt.replace(tzinfo=None).
Note that the default tzinfo.fromutc() method can be overridden in a
tzinfo subclass to effect the result returned by astimezone().

"""Interface objects
Interface objects describe the behavior of an object by containing
useful information about the object. This information includes:
o Prose documentation about the object. In Python terms, this
is called the "doc string" of the interface. In this element,
you describe how the object works in prose language and any
other useful information about the object.
o Descriptions of attributes. Attribute descriptions include
the name of the attribute and prose documentation describing
the attributes usage.
o Descriptions of methods. Method descriptions can include:
- Prose "doc string" documentation about the method and its
usage.
- A description of the methods arguments; how many arguments
are expected, optional arguments and their default values,
the position or arguments in the signature, whether the
method accepts arbitrary arguments and whether the method
accepts arbitrary keyword arguments.
o Optional tagged data. Interface objects (and their attributes and
methods) can have optional, application specific tagged data
associated with them. Examples uses for this are examples,
security assertions, pre/post conditions, and other possible
information you may want to associate with an Interface or its
attributes.
Not all of this information is mandatory. For example, you may
only want the methods of your interface to have prose
documentation and not describe the arguments of the method in
exact detail. Interface objects are flexible and let you give or
take any of these components.
Interfaces are created with the Python class statement using
either Interface.Interface or another interface, as in::
from zope.interface import Interface
class IMyInterface(Interface):
'''Interface documentation'''
def meth(arg1, arg2):
'''Documentation for meth'''
# Note that there is no self argument
class IMySubInterface(IMyInterface):
'''Interface documentation'''
def meth2():
'''Documentation for meth2'''
You use interfaces in two ways:
o You assert that your object implement the interfaces.
There are several ways that you can assert that an object
implements an interface:
1. Call zope.interface.implements in your class definition.
2. Call zope.interfaces.directlyProvides on your object.
3. Call 'zope.interface.classImplements' to assert that instances
of a class implement an interface.
For example::
from zope.interface import classImplements
classImplements(some_class, some_interface)
This approach is useful when it is not an option to modify
the class source. Note that this doesn't affect what the
class itself implements, but only what its instances
implement.
o You query interface meta-data. See the IInterface methods and
attributes for details.

# Extendors
# ---------
# When given an target interface for an adapter lookup, we need to consider
# adapters for interfaces that extend the target interface. This is
# what the extendors dictionary is about. It tells us all of the
# interfaces that extend an interface for which there are adapters
# registered.
# We could separate this by order and name, thus reducing the
# number of provided interfaces to search at run time. The tradeoff,
# however, is that we have to store more information. For example,
# is the same interface is provided for multiple names and if the
# interface extends many interfaces, we'll have to keep track of
# a fair bit of information for each name. It's better to
# be space efficient here and be time efficient in the cache
# implementation.
# TODO: add invalidation when a provided interface changes, in case
# the interface's __iro__ has changed. This is unlikely enough that
# we'll take our chances for now.

============================
4.1.0 (2014-02-05)
------------------
- Updated ``boostrap.py`` to version 2.2.
- Added ``@named(name)`` declaration, that specifies the component name, so it
does not have to be passed in during registration.
4.0.5 (2013-02-28)
------------------
- Fixed a bug where a decorated method caused false positive failures on
``verifyClass()``.
4.0.4 (2013-02-21)
------------------
- Fixed a bug that was revealed by porting zope.traversing. During a loop, the
loop body modified a weakref dict causing a ``RuntimeError`` error.
4.0.3 (2012-12-31)
------------------
- Fleshed out PyPI Trove classifiers.
4.0.2 (2012-11-21)
------------------
- Added support for Python 3.3.
- Restored ability to install the package in the absence of ``setuptools``.
- LP #1055223: Fix test which depended on dictionary order and failed randomly
in Python 3.3.
4.0.1 (2012-05-22)
------------------
- Dropped explicit ``DeprecationWarnings`` for "class advice" APIS (these
APIs are still deprecated under Python 2.x, and still raise an exception
under Python 3.x, but no longer cause a warning to be emitted under
Python 2.x).
4.0.0 (2012-05-16)
------------------
- Automated build of Sphinx HTML docs and running doctest snippets via tox.
- Deprecated the "class advice" APIs from ``zope.interface.declarations``:
``implements``, ``implementsOnly``, and ``classProvides``. In their place,
prefer the equivalent class decorators: ``@implementer``,
``@implementer_only``, and ``@provider``. Code which uses the deprecated
APIs will not work as expected under Py3k.
- Removed use of '2to3' and associated fixers when installing under Py3k.
The code is now in a "compatible subset" which supports Python 2.6, 2.7,
and 3.2, including PyPy 1.8 (the version compatible with the 2.7 language
spec).
- Dropped explicit support for Python 2.4 / 2.5 / 3.1.
- Added support for PyPy.
- Added support for continuous integration using ``tox`` and ``jenkins``.
- Added 'setup.py dev' alias (runs ``setup.py develop`` plus installs
``nose`` and ``coverage``).
- Added 'setup.py docs' alias (installs ``Sphinx`` and dependencies).
- Replaced all unittest coverage previously accomplished via doctests with
unittests. The doctests have been moved into a ``docs`` section, managed
as a Sphinx collection.
- LP #910987: Ensure that the semantics of the ``lookup`` method of
``zope.interface.adapter.LookupBase`` are the same in both the C and
Python implementations.
- LP #900906: Avoid exceptions due to tne new ``__qualname__`` attribute
added in Python 3.3 (see PEP 3155 for rationale). Thanks to Antoine
Pitrou for the patch.
3.8.0 (2011-09-22)
------------------
- New module ``zope.interface.registry``. This is code moved from
``zope.component.registry`` which implements a basic nonperistent component
registry as ``zope.interface.registry.Components``. This class was moved
from ``zope.component`` to make porting systems (such as Pyramid) that rely
only on a basic component registry to Python 3 possible without needing to
port the entirety of the ``zope.component`` package. Backwards
compatibility import shims have been left behind in ``zope.component``, so
this change will not break any existing code.
- New ``tests_require`` dependency: ``zope.event`` to test events sent by
Components implementation. The ``zope.interface`` package does not have a
hard dependency on ``zope.event``, but if ``zope.event`` is importable, it
will send component registration events when methods of an instance of
``zope.interface.registry.Components`` are called.
- New interfaces added to support ``zope.interface.registry.Components``
addition: ``ComponentLookupError``, ``Invalid``, ``IObjectEvent``,
``ObjectEvent``, ``IComponentLookup``, ``IRegistration``,
``IUtilityRegistration``, ``IAdapterRegistration``,
``ISubscriptionAdapterRegistration``, ``IHandlerRegistration``,
``IRegistrationEvent``, ``RegistrationEvent``, ``IRegistered``,
``Registered``, ``IUnregistered``, ``Unregistered``,
``IComponentRegistry``, and ``IComponents``.
- No longer Python 2.4 compatible (tested under 2.5, 2.6, 2.7, and 3.2).
3.7.0 (2011-08-13)
------------------
- Move changes from 3.6.2 - 3.6.5 to a new 3.7.x release line.
3.6.7 (2011-08-20)
------------------
- Fix sporadic failures on x86-64 platforms in tests of rich comparisons
of interfaces.
3.6.6 (2011-08-13)
------------------
- LP #570942: Now correctly compare interfaces from different modules but
with the same names.
N.B.: This is a less intrusive / destabilizing fix than the one applied in
3.6.3: we only fix the underlying cmp-alike function, rather than adding
the other "rich comparison" functions.
- Revert to software as released with 3.6.1 for "stable" 3.6 release branch.
3.6.5 (2011-08-11)
------------------
- LP #811792: work around buggy behavior in some subclasses of
``zope.interface.interface.InterfaceClass``, which invoke ``__hash__``
before initializing ``__module__`` and ``__name__``. The workaround
returns a fixed constant hash in such cases, and issues a ``UserWarning``.
- LP #804832: Under PyPy, ``zope.interface`` should not build its C
extension. Also, prevent attempting to build it under Jython.
- Add a tox.ini for easier xplatform testing.
- Fix testing deprecation warnings issued when tested under Py3K.
3.6.4 (2011-07-04)
------------------
- LP 804951: InterfaceClass instances were unhashable under Python 3.x.
3.6.3 (2011-05-26)
------------------
- LP #570942: Now correctly compare interfaces from different modules but
with the same names.
3.6.2 (2011-05-17)
------------------
- Moved detailed documentation out-of-line from PyPI page, linking instead to
http://docs.zope.org/zope.interface .
- Fixes for small issues when running tests under Python 3.2 using
``zope.testrunner``.
- LP # 675064: Specify return value type for C optimizations module init
under Python 3: undeclared value caused warnings, and segfaults on some
64 bit architectures.
- setup.py now raises RuntimeError if you don't have Distutils installed when
running under Python 3.
3.6.1 (2010-05-03)
------------------
- A non-ASCII character in the changelog made 3.6.0 uninstallable on
Python 3 systems with another default encoding than UTF-8.
- Fixed compiler warnings under GCC 4.3.3.
3.6.0 (2010-04-29)
------------------
- LP #185974: Clear the cache used by ``Specificaton.get`` inside
``Specification.changed``. Thanks to Jacob Holm for the patch.
- Added support for Python 3.1. Contributors:
Lennart Regebro
Martin v Loewis
Thomas Lotze
Wolfgang Schnerring
The 3.1 support is completely backwards compatible. However, the implements
syntax used under Python 2.X does not work under 3.X, since it depends on
how metaclasses are implemented and this has changed. Instead it now supports
a decorator syntax (also under Python 2.X)::
class Foo:
implements(IFoo)
...
can now also be written::
@implementer(IFoo):
class Foo:
...
There are 2to3 fixers available to do this change automatically in the
zope.fixers package.
- Python 2.3 is no longer supported.
3.5.4 (2009-12-23)
------------------
- Use the standard Python doctest module instead of zope.testing.doctest, which
has been deprecated.
3.5.3 (2009-12-08)
------------------
- Fix an edge case: make providedBy() work when a class has '__provides__' in
its __slots__ (see http://thread.gmane.org/gmane.comp.web.zope.devel/22490)
3.5.2 (2009-07-01)
------------------
- BaseAdapterRegistry.unregister, unsubscribe: Remove empty portions of
the data structures when something is removed. This avoids leaving
references to global objects (interfaces) that may be slated for
removal from the calling application.
3.5.1 (2009-03-18)
------------------
- verifyObject: use getattr instead of hasattr to test for object attributes
in order to let exceptions other than AttributeError raised by properties
propagate to the caller
- Add Sphinx-based documentation building to the package buildout
configuration. Use the ``bin/docs`` command after buildout.
- Improve package description a bit. Unify changelog entries formatting.
- Change package's mailing list address to zope-dev at zope.org as
zope3-dev at zope.org is now retired.
3.5.0 (2008-10-26)
------------------
- Fixed declaration of _zope_interface_coptimizations, it's not a top level
package.
- Add a DocTestSuite for odd.py module, so their tests are run.
- Allow to bootstrap on Jython.
- Fix https://bugs.launchpad.net/zope3/3.3/+bug/98388: ISpecification
was missing a declaration for __iro__.
- Added optional code optimizations support, which allows the building
of C code optimizations to fail (Jython).
- Replaced `_flatten` with a non-recursive implementation, effectively making
it 3x faster.
3.4.1 (2007-10-02)
------------------
- Fixed a setup bug that prevented installation from source on systems
without setuptools.
3.4.0 (2007-07-19)
------------------
- Final release for 3.4.0.
3.4.0b3 (2007-05-22)
--------------------
- Objects with picky custom comparison methods couldn't be added to
component registries. Now, when checking whether an object is
already registered, identity comparison is used.
3.3.0.1 (2007-01-03)
--------------------
- Made a reference to OverflowWarning, which disappeared in Python
2.5, conditional.
3.3.0 (2007/01/03)
------------------
New Features
++++++++++++
- The adapter-lookup algorithim was refactored to make it
much simpler and faster.
Also, more of the adapter-lookup logic is implemented in C, making
debugging of application code easier, since there is less
infrastructre code to step through.
- We now treat objects without interface declarations as if they
declared that they provide zope.interface.Interface.
- There are a number of richer new adapter-registration interfaces
that provide greater control and introspection.
- Added a new interface decorator to zope.interface that allows the
setting of tagged values on an interface at definition time (see
zope.interface.taggedValue).
Bug Fixes
+++++++++
- A bug in multi-adapter lookup sometimes caused incorrect adapters to
be returned.
3.2.0.2 (2006-04-15)
--------------------
- Fix packaging bug: 'package_dir' must be a *relative* path.
3.2.0.1 (2006-04-14)
--------------------
- Packaging change: suppress inclusion of 'setup.cfg' in 'sdist' builds.
3.2.0 (2006-01-05)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope 3.2.0 release.
3.1.0 (2005-10-03)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope 3.1.0 release.
- Made attribute resolution order consistent with component lookup order,
i.e. new-style class MRO semantics.
- Deprecated 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in
favor of 'implementedBy' and 'providedBy'.
3.0.1 (2005-07-27)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope X3.0.1 release.
- Fixed a bug reported by James Knight, which caused adapter registries
to fail occasionally to reflect declaration changes.
3.0.0 (2004-11-07)
------------------
- Corresponds to the verison of the zope.interface package shipped as part of
the Zope X3.0.0 release.

=========================
This package is intended to be independently reusable in any Python
project. It is maintained by the `Zope Toolkit project
`_.
This package provides an implementation of "object interfaces" for Python.
Interfaces are a mechanism for labeling objects as conforming to a given
API or contract. So, this package can be considered as implementation of
the `Design By Contract`_ methodology support in Python.

# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in. You must
# make exactly 11 lines for the formatting to be correct. It's also
# customary to leave one space after the ':' except on otherwise blank lines.
