-/* We try to define Py_LIMITED_API before including Python.h.
-
- Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
- Py_REF_DEBUG are not defined. This is a best-effort approximation:
- we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
- the same works for the other two macros. Py_DEBUG implies them,
- but not the other way around.
-
- The implementation is messy (issue #350): on Windows, with _MSC_VER,
- we have to define Py_LIMITED_API even before including pyconfig.h.
- In that case, we guess what pyconfig.h will do to the macros above,
- and check our guess after the #include.
-
- Note that on Windows, with CPython 3.x, you need >= 3.5 and virtualenv
- version >= 16.0.0. With older versions of either, you don't get a
- copy of PYTHON3.DLL in the virtualenv. We can't check the version of
- CPython *before* we even include pyconfig.h. ffi.set_source() puts
- a ``#define _CFFI_NO_LIMITED_API'' at the start of this file if it is
- running on Windows < 3.5, as an attempt at fixing it, but that's
- arguably wrong because it may not be the target version of Python.
- Still better than nothing I guess. As another workaround, you can
- remove the definition of Py_LIMITED_API here.
-
- See also 'py_limited_api' in cffi/setuptools_ext.py.

-
-
-``cryptography`` is a package which provides cryptographic recipes and
-primitives to Python developers. Our goal is for it to be your "cryptographic
-standard library". It supports Python 3.7+ and PyPy3 7.3.11+.
-
-``cryptography`` includes both high level recipes and low level interfaces to
-common cryptographic algorithms such as symmetric ciphers, message digests, and
-key derivation functions. For example, to encrypt something with
-``cryptography``'s high level symmetric encryption recipe:
-
-.. code-block:: pycon
-
- >>> from cryptography.fernet import Fernet
- >>> # Put this somewhere safe!
- >>> key = Fernet.generate_key()
- >>> f = Fernet(key)
- >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
- >>> token
- b'...'
- >>> f.decrypt(token)
- b'A really secret message. Not for prying eyes.'
-
-You can find more information in the `documentation`_.
-
-You can install ``cryptography`` with:
-
-.. code-block:: console
-
- $ pip install cryptography
-
-For full details see `the installation documentation`_.
-
-Discussion
-~~~~~~~~~~
-
-If you run into bugs, you can file them in our `issue tracker`_.
-
-We maintain a `cryptography-dev`_ mailing list for development discussion.
-
-You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get
-involved.

-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.

-
-
-5.5.2 (2022-11-17)
-==================
-
-- Add support for building arm64 wheels on macOS.
-
-
-5.5.1 (2022-11-03)
-==================
-
-- Add support for final Python 3.11 release.
-
-
-5.5.0 (2022-10-10)
-==================
-
-- Add support for Python 3.10 and 3.11 (as of 3.11.0rc2).
-
-- Add missing Trove classifier showing support for Python 3.9.
-
-- Add some more entries to ``zope.interface.interfaces.__all__``.
-
-- Disable unsafe math optimizations in C code. See `pull request 262
- `_.
-
-
-5.4.0 (2021-04-15)
-==================
-
-- Make the C implementation of the ``__providedBy__`` descriptor stop
- ignoring all errors raised when accessing the instance's
- ``__provides__``. Now it behaves like the Python version and only
- catches ``AttributeError``. The previous behaviour could lead to
- crashing the interpreter in cases of recursion and errors. See
- `issue 239 `_.
-
-- Update the ``repr()`` and ``str()`` of various objects to be shorter
- and more informative. In many cases, the ``repr()`` is now something
- that can be evaluated to produce an equal object. For example, what
- was previously printed as ```` is now
- shown as ``classImplements(list, IMutableSequence, IIterable)``. See
- `issue 236 `_.
-
-- Make ``Declaration.__add__`` (as in ``implementedBy(Cls) +
- ISomething``) try harder to preserve a consistent resolution order
- when the two arguments share overlapping pieces of the interface
- inheritance hierarchy. Previously, the right hand side was always
- put at the end of the resolution order, which could easily produce
- invalid orders. See `issue 193
- `_.
-
-5.3.0 (2020-03-21)
-==================
-
-- No changes from 5.3.0a1
-
-
-5.3.0a1 (2021-03-18)
-====================
-
-- Improve the repr of ``zope.interface.Provides`` to remove ambiguity
- about what is being provided. This is especially helpful diagnosing
- IRO issues.
-
-- Allow subclasses of ``BaseAdapterRegistry`` (including
- ``AdapterRegistry`` and ``VerifyingAdapterRegistry``) to have
- control over the data structures. This allows persistent
- implementations such as those based on ZODB to choose more scalable
- options (e.g., BTrees instead of dicts). See `issue 224
- `_.
-
-- Fix a reference counting issue in ``BaseAdapterRegistry`` that could
- lead to references to interfaces being kept around even when all
- utilities/adapters/subscribers providing that interface have been
- removed. This is mostly an issue for persistent implementations.
- Note that this only corrects the issue moving forward, it does not
- solve any already corrupted reference counts. See `issue 227
- `_.
-
-- Add the method ``BaseAdapterRegistry.rebuild()``. This can be used
- to fix the reference counting issue mentioned above, as well as to
- update the data structures when custom data types have changed.
-
-- Add the interface method ``IAdapterRegistry.subscribed()`` and
- implementation ``BaseAdapterRegistry.subscribed()`` for querying
- directly registered subscribers. See `issue 230
- `_.
-
-- Add the maintenance method
- ``Components.rebuildUtilityRegistryFromLocalCache()``. Most users
- will not need this, but it can be useful if the ``Components.utilities``
- registry is suspected to be out of sync with the ``Components``
- object itself (this might happen to persistent ``Components``
- implementations in the face of bugs).
-
-- Fix the ``Provides`` and ``ClassProvides`` descriptors to stop
- allowing redundant interfaces (those already implemented by the
- underlying class or meta class) to produce an inconsistent
- resolution order. This is similar to the change in ``@implementer``
- in 5.1.0, and resolves inconsistent resolution orders with
- ``zope.proxy`` and ``zope.location``. See `issue 207
- `_.
-
-5.2.0 (2020-11-05)
-==================
-
-- Add documentation section ``Persistency and Equality``
- (`#218 `_).
-
-- Create arm64 wheels.
-
-- Add support for Python 3.9.
-
-
-5.1.2 (2020-10-01)
-==================
-
-- Make sure to call each invariant only once when validating invariants.
- Previously, invariants could be called multiple times because when an
- invariant is defined in an interface, it's found by in all interfaces
- inheriting from that interface. See `pull request 215
- `_.
-
-5.1.1 (2020-09-30)
-==================
-
-- Fix the method definitions of ``IAdapterRegistry.subscribe``,
- ``subscriptions`` and ``subscribers``. Previously, they all were
- defined to accept a ``name`` keyword argument, but subscribers have
- no names and the implementation of that interface did not accept
- that argument. See `issue 208
- `_.
-
-- Fix a potential reference leak in the C optimizations. Previously,
- applications that dynamically created unique ``Specification``
- objects (e.g., used ``@implementer`` on dynamic classes) could
- notice a growth of small objects over time leading to increased
- garbage collection times. See `issue 216
- `_.
-
- .. caution::
-
- This leak could prevent interfaces used as the bases of
- other interfaces from being garbage collected. Those interfaces
- will now be collected.
-
- One way in which this would manifest was that ``weakref.ref``
- objects (and things built upon them, like
- ``Weak[Key|Value]Dictionary``) would continue to have access to
- the original object even if there were no other visible
- references to Python and the original object *should* have been
- collected. This could be especially problematic for the
- ``WeakKeyDictionary`` when combined with dynamic or local
- (created in the scope of a function) interfaces, since interfaces
- are hashed based just on their name and module name. See the
- linked issue for an example of a resulting ``KeyError``.
-
- Note that such potential errors are not new, they are just once
- again a possibility.
-
-5.1.0 (2020-04-08)
-==================
-
-- Make ``@implementer(*iface)`` and ``classImplements(cls, *iface)``
- ignore redundant interfaces. If the class already implements an
- interface through inheritance, it is no longer redeclared
- specifically for *cls*. This solves many instances of inconsistent
- resolution orders, while still allowing the interface to be declared
- for readability and maintenance purposes. See `issue 199
- `_.
-
-- Remove all bare ``except:`` statements. Previously, when accessing
- special attributes such as ``__provides__``, ``__providedBy__``,
- ``__class__`` and ``__conform__``, this package wrapped such access
- in a bare ``except:`` statement, meaning that many errors could pass
- silently; typically this would result in a fallback path being taken
- and sometimes (like with ``providedBy()``) the result would be
- non-sensical. This is especially true when those attributes are
- implemented with descriptors. Now, only ``AttributeError`` is
- caught. This makes errors more obvious.
-
- Obviously, this means that some exceptions will be propagated
- differently than before. In particular, ``RuntimeError`` raised by
- Acquisition in the case of circular containment will now be
- propagated. Previously, when adapting such a broken object, a
- ``TypeError`` would be the common result, but now it will be a more
- informative ``RuntimeError``.
-
- In addition, ZODB errors like ``POSKeyError`` could now be
- propagated where previously they would ignored by this package.
-
- See `issue 200 `_.
-
-- Require that the second argument (*bases*) to ``InterfaceClass`` is
- a tuple. This only matters when directly using ``InterfaceClass`` to
- create new interfaces dynamically. Previously, an individual
- interface was allowed, but did not work correctly. Now it is
- consistent with ``type`` and requires a tuple.
-
-- Let interfaces define custom ``__adapt__`` methods. This implements
- the other side of the :pep:`246` adaptation protocol: objects being
- adapted could already implement ``__conform__`` if they know about
- the interface, and now interfaces can implement ``__adapt__`` if
- they know about particular objects. There is no performance penalty
- for interfaces that do not supply custom ``__adapt__`` methods.
-
- This includes the ability to add new methods, or override existing
- interface methods using the new ``@interfacemethod`` decorator.
-
- See `issue 3 `_.
-
-- Make the internal singleton object returned by APIs like
- ``implementedBy`` and ``directlyProvidedBy`` for objects that
- implement or provide no interfaces more immutable. Previously an
- internal cache could be mutated. See `issue 204
- `_.
-
-5.0.2 (2020-03-30)
-==================
-
-- Ensure that objects that implement no interfaces (such as direct
- subclasses of ``object``) still include ``Interface`` itself in
- their ``__iro___`` and ``__sro___``. This fixes adapter registry
- lookups for such objects when the adapter is registered for
- ``Interface``. See `issue 197
- `_.
-
-
-5.0.1 (2020-03-21)
-==================
-
-- Ensure the resolution order for ``InterfaceClass`` is consistent.
- See `issue 192 `_.
-
-- Ensure the resolution order for ``collections.OrderedDict`` is
- consistent on CPython 2. (It was already consistent on Python 3 and PyPy).
-
-- Fix the handling of the ``ZOPE_INTERFACE_STRICT_IRO`` environment
- variable. Previously, ``ZOPE_INTERFACE_STRICT_RO`` was read, in
- contrast with the documentation. See `issue 194
- `_.
-
-
-5.0.0 (2020-03-19)
-==================
-
-- Make an internal singleton object returned by APIs like
- ``implementedBy`` and ``directlyProvidedBy`` immutable. Previously,
- it was fully mutable and allowed changing its ``__bases___``. That
- could potentially lead to wrong results in pathological corner
- cases. See `issue 158
- `_.
-
-- Support the ``PURE_PYTHON`` environment variable at runtime instead
- of just at wheel build time. A value of 0 forces the C extensions to
- be used (even on PyPy) failing if they aren't present. Any other
- value forces the Python implementation to be used, ignoring the C
- extensions. See `PR 151 `_.
-
-- Cache the result of ``__hash__`` method in ``InterfaceClass`` as a
- speed optimization. The method is called very often (i.e several
- hundred thousand times during Plone 5.2 startup). Because the hash value never
- changes it can be cached. This improves test performance from 0.614s
- down to 0.575s (1.07x faster). In a real world Plone case a reindex
- index came down from 402s to 320s (1.26x faster). See `PR 156
- `_.
-
-- Change the C classes ``SpecificationBase`` and its subclass
- ``ClassProvidesBase`` to store implementation attributes in their structures
- instead of their instance dictionaries. This eliminates the use of
- an undocumented private C API function, and helps make some
- instances require less memory. See `PR 154 `_.
-
-- Reduce memory usage in other ways based on observations of usage
- patterns in Zope (3) and Plone code bases.
-
- - Specifications with no dependents are common (more than 50%) so
- avoid allocating a ``WeakKeyDictionary`` unless we need it.
- - Likewise, tagged values are relatively rare, so don't allocate a
- dictionary to hold them until they are used.
- - Use ``__slots___`` or the C equivalent ``tp_members`` in more
- common places. Note that this removes the ability to set arbitrary
- instance variables on certain objects.
- See `PR 155 `_.
-
- The changes in this release resulted in a 7% memory reduction after
- loading about 6,000 modules that define about 2,200 interfaces.
-
- .. caution::
-
- Details of many private attributes have changed, and external use
- of those private attributes may break. In particular, the
- lifetime and default value of ``_v_attrs`` has changed.
-
-- Remove support for hashing uninitialized interfaces. This could only
- be done by subclassing ``InterfaceClass``. This has generated a
- warning since it was first added in 2011 (3.6.5). Please call the
- ``InterfaceClass`` constructor or otherwise set the appropriate
- fields in your subclass before attempting to hash or sort it. See
- `issue 157 `_.
-
-- Remove unneeded override of the ``__hash__`` method from
- ``zope.interface.declarations.Implements``. Watching a reindex index
- process in ZCatalog with on a Py-Spy after 10k samples the time for
- ``.adapter._lookup`` was reduced from 27.5s to 18.8s (~1.5x faster).
- Overall reindex index time shrunk from 369s to 293s (1.26x faster).
- See `PR 161
- `_.
-
-- Make the Python implementation closer to the C implementation by
- ignoring all exceptions, not just ``AttributeError``, during (parts
- of) interface adaptation. See `issue 163
- `_.
-
-- Micro-optimization in ``.adapter._lookup`` , ``.adapter._lookupAll``
- and ``.adapter._subscriptions``: By loading ``components.get`` into
- a local variable before entering the loop a bytcode "LOAD_FAST 0
- (components)" in the loop can be eliminated. In Plone, while running
- all tests, average speedup of the "owntime" of ``_lookup`` is ~5x.
- See `PR 167
- `_.
-
-- Add ``__all__`` declarations to all modules. This helps tools that
- do auto-completion and documentation and results in less cluttered
- results. Wildcard ("*") are not recommended and may be affected. See
- `issue 153
- `_.
-
-- Fix ``verifyClass`` and ``verifyObject`` for builtin types like
- ``dict`` that have methods taking an optional, unnamed argument with
- no default value like ``dict.pop``. On PyPy3, the verification is
- strict, but on PyPy2 (as on all versions of CPython) those methods
- cannot be verified and are ignored. See `issue 118
- `_.
-
-- Update the common interfaces ``IEnumerableMapping``,
- ``IExtendedReadMapping``, ``IExtendedWriteMapping``,
- ``IReadSequence`` and ``IUniqueMemberWriteSequence`` to no longer
- require methods that were removed from Python 3 on Python 3, such as
- ``__setslice___``. Now, ``dict``, ``list`` and ``tuple`` properly
- verify as ``IFullMapping``, ``ISequence`` and ``IReadSequence,``
- respectively on all versions of Python.
-
-- Add human-readable ``__str___`` and ``__repr___`` to ``Attribute``
- and ``Method``. These contain the name of the defining interface
- and the attribute. For methods, it also includes the signature.
-
-- Change the error strings raised by ``verifyObject`` and
- ``verifyClass``. They now include more human-readable information
- and exclude extraneous lines and spaces. See `issue 170
- `_.
-
- .. caution:: This will break consumers (such as doctests) that
- depended on the exact error messages.
-
-- Make ``verifyObject`` and ``verifyClass`` report all errors, if the
- candidate object has multiple detectable violations. Previously they
- reported only the first error. See `issue
- `_.
-
- Like the above, this will break consumers depending on the exact
- output of error messages if more than one error is present.
-
-- Add ``zope.interface.common.collections``,
- ``zope.interface.common.numbers``, and ``zope.interface.common.io``.
- These modules define interfaces based on the ABCs defined in the
- standard library ``collections.abc``, ``numbers`` and ``io``
- modules, respectively. Importing these modules will make the
- standard library concrete classes that are registered with those
- ABCs declare the appropriate interface. See `issue 138
- `_.
-
-- Add ``zope.interface.common.builtins``. This module defines
- interfaces of common builtin types, such as ``ITextString`` and
- ``IByteString``, ``IDict``, etc. These interfaces extend the
- appropriate interfaces from ``collections`` and ``numbers``, and the
- standard library classes implement them after importing this module.
- This is intended as a replacement for third-party packages like
- `dolmen.builtins `_.
- See `issue 138 `_.
-
-- Make ``providedBy()`` and ``implementedBy()`` respect ``super``
- objects. For instance, if class ``Derived`` implements ``IDerived``
- and extends ``Base`` which in turn implements ``IBase``, then
- ``providedBy(super(Derived, derived))`` will return ``[IBase]``.
- Previously it would have returned ``[IDerived]`` (in general, it
- would previously have returned whatever would have been returned
- without ``super``).
-
- Along with this change, adapter registries will unpack ``super``
- objects into their ``__self___`` before passing it to the factory.
- Together, this means that ``component.getAdapter(super(Derived,
- self), ITarget)`` is now meaningful.
-
- See `issue 11 `_.
-
-- Fix a potential interpreter crash in the low-level adapter
- registry lookup functions. See issue 11.
-
-- Adopt Python's standard `C3 resolution order
- `_ to compute the
- ``__iro__`` and ``__sro__`` of interfaces, with tweaks to support
- additional cases that are common in interfaces but disallowed for
- Python classes. Previously, an ad-hoc ordering that made no
- particular guarantees was used.
-
- This has many beneficial properties, including the fact that base
- interface and base classes tend to appear near the end of the
- resolution order instead of the beginning. The resolution order in
- general should be more predictable and consistent.
-
- .. caution::
- In some cases, especially with complex interface inheritance
- trees or when manually providing or implementing interfaces, the
- resulting IRO may be quite different. This may affect adapter
- lookup.
-
- The C3 order enforces some constraints in order to be able to
- guarantee a sensible ordering. Older versions of zope.interface did
- not impose similar constraints, so it was possible to create
- interfaces and declarations that are inconsistent with the C3
- constraints. In that event, zope.interface will still produce a
- resolution order equal to the old order, but it won't be guaranteed
- to be fully C3 compliant. In the future, strict enforcement of C3
- order may be the default.
-
- A set of environment variables and module constants allows
- controlling several aspects of this new behaviour. It is possible to
- request warnings about inconsistent resolution orders encountered,
- and even to forbid them. Differences between the C3 resolution order
- and the previous order can be logged, and, in extreme cases, the
- previous order can still be used (this ability will be removed in
- the future). For details, see the documentation for
- ``zope.interface.ro``.
-
-- Make inherited tagged values in interfaces respect the resolution
- order (``__iro__``), as method and attribute lookup does. Previously
- tagged values could give inconsistent results. See `issue 190
- `_.
-
-- Add ``getDirectTaggedValue`` (and related methods) to interfaces to
- allow accessing tagged values irrespective of inheritance. See
- `issue 190
- `_.
-
-- Ensure that ``Interface`` is always the last item in the ``__iro__``
- and ``__sro__``. This is usually the case, but if classes that do
- not implement any interfaces are part of a class inheritance
- hierarchy, ``Interface`` could be assigned too high a priority.
- See `issue 8 `_.
-
-- Implement sorting, equality, and hashing in C for ``Interface``
- objects. In micro benchmarks, this makes those operations 40% to 80%
- faster. This translates to a 20% speed up in querying adapters.
-
- Note that this changes certain implementation details. In
- particular, ``InterfaceClass`` now has a non-default metaclass, and
- it is enforced that ``__module__`` in instances of
- ``InterfaceClass`` is read-only.
-
- See `PR 183 `_.
-
-
-4.7.2 (2020-03-10)

- values by following ``__bases__``. See `PR 144
- `_.
-
- .. caution:: This may be a breaking change.
-
-- Add support for Python 3.8.
-
-
-4.6.0 (2018-10-23)
-==================
-
-- Add support for Python 3.7

-
-
-4.4.3 (2017-09-22)
-==================
-
-- Avoid exceptions when the ``__annotations__`` attribute is added to
- interface definitions with Python 3.x type hints. See `issue 98
- `_.

-==================
-
-- Fix a regression storing
- ``zope.component.persistentregistry.PersistentRegistry`` instances.
- See `issue 85 `_.
-
-- Fix a regression that could lead to the utility registration cache
- of ``Components`` getting out of sync. See `issue 93
- `_.
-
-4.4.1 (2017-05-13)
-==================
-
-- Simplify the caching of utility-registration data. In addition to
- simplification, avoids spurious test failures when checking for
- leaks in tests with persistent registries. See `pull 84
- `_.
-
-- Raise ``ValueError`` when non-text names are passed to adapter registry
- methods: prevents corruption of lookup caches.
-
-4.4.0 (2017-04-21)
-==================
-
-- Avoid a warning from the C compiler.
- (https://github.com/zopefoundation/zope.interface/issues/71)
-
-- Add support for Python 3.6.
-
-4.3.3 (2016-12-13)
-==================
-
-- Correct typos and ReST formatting errors in documentation.
-
-- Add API documentation for the adapter registry.

-==================
-
-- Support Components subclasses that are not hashable.
- (https://github.com/zopefoundation/zope.interface/issues/53)
-
-
-4.3.0 (2016-08-31)
-==================
-
-- Add the ability to sort the objects returned by ``implementedBy``.
- This is compatible with the way interface classes sort so they can
- be used together in ordered containers like BTrees.
- (https://github.com/zopefoundation/zope.interface/issues/42)
-
-- Make ``setuptools`` a hard dependency of ``setup.py``.
- (https://github.com/zopefoundation/zope.interface/issues/13)
-
-- Change a linear algorithm (O(n)) in ``Components.registerUtility`` and
- ``Components.unregisterUtility`` into a dictionary lookup (O(1)) for
- hashable components. This substantially improves the time taken to
- manipulate utilities in large registries at the cost of some
- additional memory usage. (https://github.com/zopefoundation/zope.interface/issues/46)
-
-
-4.2.0 (2016-06-10)
-==================
-

-
-
-4.1.1 (2014-03-19)
-==================
-
-- Add support for Python 3.4.
-
-
-4.1.0 (2014-02-05)
-==================
-
-- Update ``boostrap.py`` to version 2.2.
-
-- Add ``@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)
-==================
-
-- Fix a bug where a decorated method caused false positive failures on
- ``verifyClass()``.
-
-
-4.0.4 (2013-02-21)
-==================
-
-- Fix 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)
-==================
-
-- Add 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)
-==================
-
-- Drop 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.
-
-- Deprecate 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.
-
-- Remove 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).
-
-- Drop explicit support for Python 2.4 / 2.5 / 3.1.
-
-- Add support for PyPy.
-
-- Add support for continuous integration using ``tox`` and ``jenkins``.
-
-- Add 'setup.py dev' alias (runs ``setup.py develop`` plus installs
- ``nose`` and ``coverage``).
-
-- Add 'setup.py docs' alias (installs ``Sphinx`` and dependencies).
-
-- Replace 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.
-
-- Fix 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.
-
-- Add 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)
-==================
-
-- Fix 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__.
-
-- Add optional code optimizations support, which allows the building
- of C code optimizations to fail (Jython).
-
-- Replace `_flatten` with a non-recursive implementation, effectively making
- it 3x faster.
-
-
-3.4.1 (2007-10-02)
-==================
-
-- Fix 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)
-====================
-
-
-- When checking whether an object is already registered, use identity
- comparison, to allow adding registering with picky custom comparison methods.
-
-
-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
-------------
-
-- Refactor the adapter-lookup algorithim to make it much simpler and faster.
-
- Also, implement more of the adapter-lookup logic in C, making
- debugging of application code easier, since there is less
- infrastructre code to step through.
-
-- Treat objects without interface declarations as if they
- declared that they provide ``zope.interface.Interface``.
-
-- Add a number of richer new adapter-registration interfaces
- that provide greater control and introspection.
-
-- Add 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.

-- Made attribute resolution order consistent with component lookup order,
- i.e. new-style class MRO semantics.
-
-- Deprecate 'isImplementedBy' and 'isImplementedByInstancesOf' APIs in
- favor of 'implementedBy' and 'providedBy'.
-
-
-3.0.1 (2005-07-27)
-==================
-
-- Corresponds to the version of the zope.interface package shipped as part of
- the Zope X3.0.1 release.

-"""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.

-class BaseAdapterRegistry:
- """
- A basic implementation of the data storage and algorithms required
- for a :class:`zope.interface.interfaces.IAdapterRegistry`.
-
- Subclasses can set the following attributes to control how the data
- is stored; in particular, these hooks can be helpful for ZODB
- persistence. They can be class attributes that are the named (or similar) type, or
- they can be methods that act as a constructor for an object that behaves
- like the types defined here; this object will not assume that they are type
- objects, but subclasses are free to do so:
-
- _sequenceType = list
- This is the type used for our two mutable top-level "byorder" sequences.
- Must support mutation operations like ``append()`` and ``del seq[index]``.
- These are usually small (< 10). Although at least one of them is
- accessed when performing lookups or queries on this object, the other
- is untouched. In many common scenarios, both are only required when
- mutating registrations and subscriptions (like what
- :meth:`zope.interface.interfaces.IComponents.registerUtility` does).
- This use pattern makes it an ideal candidate to be a
- :class:`~persistent.list.PersistentList`.
- _leafSequenceType = tuple
- This is the type used for the leaf sequences of subscribers.
- It could be set to a ``PersistentList`` to avoid many unnecessary data
- loads when subscribers aren't being used. Mutation operations are directed
- through :meth:`_addValueToLeaf` and :meth:`_removeValueFromLeaf`; if you use
- a mutable type, you'll need to override those.
- _mappingType = dict
- This is the mutable mapping type used for the keyed mappings.
- A :class:`~persistent.mapping.PersistentMapping`
- could be used to help reduce the number of data loads when the registry is large
- and parts of it are rarely used. Further reductions in data loads can come from
- using a :class:`~BTrees.OOBTree.OOBTree`, but care is required
- to be sure that all required/provided
- values are fully ordered (e.g., no required or provided values that are classes
- can be used).
- _providedType = dict
- This is the mutable mapping type used for the ``_provided`` mapping.
- This is separate from the generic mapping type because the values
- are always integers, so one might choose to use a more optimized data
- structure such as a :class:`~BTrees.OIBTree.OIBTree`.
- The same caveats regarding key types
- apply as for ``_mappingType``.
-
- It is possible to also set these on an instance, but because of the need to
- potentially also override :meth:`_addValueToLeaf` and :meth:`_removeValueFromLeaf`,
- this may be less useful in a persistent scenario; using a subclass is recommended.
-
- .. versionchanged:: 5.3.0
- Add support for customizing the way internal data
- structures are created.
- .. versionchanged:: 5.3.0
- Add methods :meth:`rebuild`, :meth:`allRegistrations`
- and :meth:`allSubscriptions`.

-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.

- """
- An interface that is automatically derived from a
- :class:`abc.ABCMeta` type.
-
- Internal use only.
-
- The body of the interface definition *must* define
- a property ``abc`` that is the ABC to base the interface on.
-
- If ``abc`` is *not* in the interface definition, a regular
- interface will be defined instead (but ``extra_classes`` is still
- respected).
-
- Use the ``@optional`` decorator on method definitions if
- the ABC defines methods that are not actually required in all cases
- because the Python language has multiple ways to implement a protocol.
- For example, the ``iter()`` protocol can be implemented with
- ``__iter__`` or the pair ``__len__`` and ``__getitem__``.
-
- When created, any existing classes that are registered to conform
- to the ABC are declared to implement this interface. This is *not*
- automatically updated as the ABC registry changes. If the body of the
- interface definition defines ``extra_classes``, it should be a
- tuple giving additional classes to declare implement the interface.
-
- Note that this is not fully symmetric. For example, it is usually
- the case that a subclass relationship carries the interface
- declarations over::
-
- >>> from zope.interface import Interface
- >>> class I1(Interface):
- ... pass
- ...
- >>> from zope.interface import implementer
- >>> @implementer(I1)
- ... class Root(object):
- ... pass
- ...
- >>> class Child(Root):
- ... pass
- ...
- >>> child = Child()
- >>> isinstance(child, Root)
- True
- >>> from zope.interface import providedBy
- >>> list(providedBy(child))
- []
-
- However, that's not the case with ABCs and ABC interfaces. Just
- because ``isinstance(A(), AnABC)`` and ``isinstance(B(), AnABC)``
- are both true, that doesn't mean there's any class hierarchy
- relationship between ``A`` and ``B``, or between either of them
- and ``AnABC``. Thus, if ``AnABC`` implemented ``IAnABC``, it would
- not follow that either ``A`` or ``B`` implements ``IAnABC`` (nor
- their instances provide it)::
-
- >>> class SizedClass(object):
- ... def __len__(self): return 1
- ...
- >>> from collections.abc import Sized
- >>> isinstance(SizedClass(), Sized)
- True
- >>> from zope.interface import classImplements
- >>> classImplements(Sized, I1)
- None
- >>> list(providedBy(SizedClass()))
- []
-
- Thus, to avoid conflicting assumptions, ABCs should not be
- declared to implement their parallel ABC interface. Only concrete
- classes specifically registered with the ABC should be declared to
- do so.

- # Handling ``__module__`` on ``InterfaceClass`` is tricky. We need
- # to be able to read it on a type and get the expected string. We
- # also need to be able to set it on an instance and get the value
- # we set. So far so good. But what gets tricky is that we'd like
- # to store the value in the C structure (``InterfaceBase.__ibmodule__``) for
- # direct access during equality, sorting, and hashing. "No
- # problem, you think, I'll just use a property" (well, the C
- # equivalents, ``PyMemberDef`` or ``PyGetSetDef``).
- #
- # Except there is a problem. When a subclass is created, the
- # metaclass (``type``) always automatically puts the expected
- # string in the class's dictionary under ``__module__``, thus
- # overriding the property inherited from the superclass. Writing
- # ``Subclass.__module__`` still works, but
- # ``Subclass().__module__`` fails.
- #
- # There are multiple ways to work around this:
- #
- # (1) Define ``InterfaceBase.__getattribute__`` to watch for
- # ``__module__`` and return the C storage.
- #
- # This works, but slows down *all* attribute access (except,
- # ironically, to ``__module__``) by about 25% (40ns becomes 50ns)
- # (when implemented in C). Since that includes methods like
- # ``providedBy``, that's probably not acceptable.
- #
- # All the other methods involve modifying subclasses. This can be
- # done either on the fly in some cases, as instances are
- # constructed, or by using a metaclass. These next few can be done on the fly.
- #
- # (2) Make ``__module__`` a descriptor in each subclass dictionary.
- # It can't be a straight up ``@property`` descriptor, though, because accessing
- # it on the class returns a ``property`` object, not the desired string.
- #
- # (3) Implement a data descriptor (``__get__`` and ``__set__``)
- # that is both a subclass of string, and also does the redirect of
- # ``__module__`` to ``__ibmodule__`` and does the correct thing
- # with the ``instance`` argument to ``__get__`` is None (returns
- # the class's value.) (Why must it be a subclass of string? Because
- # when it' s in the class's dict, it's defined on an *instance* of the
- # metaclass; descriptors in an instance's dict aren't honored --- their
- # ``__get__`` is never invoked --- so it must also *be* the value we want
- # returned.)
- #
- # This works, preserves the ability to read and write
- # ``__module__``, and eliminates any penalty accessing other
- # attributes. But it slows down accessing ``__module__`` of
- # instances by 200% (40ns to 124ns), requires editing class dicts on the fly
- # (in InterfaceClass.__init__), thus slightly slowing down all interface creation,
- # and is ugly.
- #
- # (4) As in the last step, but make it a non-data descriptor (no ``__set__``).
- #
- # If you then *also* store a copy of ``__ibmodule__`` in
- # ``__module__`` in the instance's dict, reading works for both
- # class and instance and is full speed for instances. But the cost
- # is storage space, and you can't write to it anymore, not without
- # things getting out of sync.
- #
- # (Actually, ``__module__`` was never meant to be writable. Doing
- # so would break BTrees and normal dictionaries, as well as the
- # repr, maybe more.)
- #
- # That leaves us with a metaclass. (Recall that a class is an
- # instance of its metaclass, so properties/descriptors defined in
- # the metaclass are used when accessing attributes on the
- # instance/class. We'll use that to define ``__module__``.) Here
- # we can have our cake and eat it too: no extra storage, and
- # C-speed access to the underlying storage. The only substantial
- # cost is that metaclasses tend to make people's heads hurt. (But
- # still less than the descriptor-is-string, hopefully.)

-
- Interface objects describe the behavior of an object by containing
- useful information about the object. This information includes:
-
- - 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.
-
- - Descriptions of attributes. Attribute descriptions include
- the name of the attribute and prose documentation describing
- the attributes usage.
-
- - 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.
-
- - 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 `zope.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:
-
- - You assert that your object implement the interfaces.
-
- There are several ways that you can declare that an object
- provides an interface:
-
- 1. Call `zope.interface.implementer` on your class definition.
-
- 2. Call `zope.interface.directlyProvides` on your object.
-
- 3. Call `zope.interface.classImplements` to declare 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.
-
- - You query interface meta-data. See the IInterface methods and

-Compute a resolution order for an object and its bases.
-
-.. versionchanged:: 5.0
- The resolution order is now based on the same C3 order that Python
- uses for classes. In complex instances of multiple inheritance, this
- may result in a different ordering.
-
- In older versions, the ordering wasn't required to be C3 compliant,
- and for backwards compatibility, it still isn't. If the ordering
- isn't C3 compliant (if it is *inconsistent*), zope.interface will
- make a best guess to try to produce a reasonable resolution order.
- Still (just as before), the results in such cases may be
- surprising.
-
-.. rubric:: Environment Variables
-
-Due to the change in 5.0, certain environment variables can be used to control errors
-and warnings about inconsistent resolution orders. They are listed in priority order, with
-variables at the bottom generally overriding variables above them.
-
-ZOPE_INTERFACE_WARN_BAD_IRO
- If this is set to "1", then if there is at least one inconsistent resolution
- order discovered, a warning (:class:`InconsistentResolutionOrderWarning`) will
- be issued. Use the usual warning mechanisms to control this behaviour. The warning
- text will contain additional information on debugging.
-ZOPE_INTERFACE_TRACK_BAD_IRO
- If this is set to "1", then zope.interface will log information about each
- inconsistent resolution order discovered, and keep those details in memory in this module
- for later inspection.
-ZOPE_INTERFACE_STRICT_IRO
- If this is set to "1", any attempt to use :func:`ro` that would produce a non-C3
- ordering will fail by raising :class:`InconsistentResolutionOrderError`.
-
-.. important::
-
- ``ZOPE_INTERFACE_STRICT_IRO`` is intended to become the default in the future.
-
-There are two environment variables that are independent.
-
-ZOPE_INTERFACE_LOG_CHANGED_IRO
- If this is set to "1", then if the C3 resolution order is different from
- the legacy resolution order for any given object, a message explaining the differences
- will be logged. This is intended to be used for debugging complicated IROs.
-ZOPE_INTERFACE_USE_LEGACY_IRO
- If this is set to "1", then the C3 resolution order will *not* be used. The
- legacy IRO will be used instead. This is a temporary measure and will be removed in the
- future. It is intended to help during the transition.
- It implies ``ZOPE_INTERFACE_LOG_CHANGED_IRO``.
-
-.. rubric:: Debugging Behaviour Changes in zope.interface 5
-
-Most behaviour changes from zope.interface 4 to 5 are related to
-inconsistent resolution orders. ``ZOPE_INTERFACE_STRICT_IRO`` is the
-most effective tool to find such inconsistent resolution orders, and
-we recommend running your code with this variable set if at all
-possible. Doing so will ensure that all interface resolution orders
-are consistent, and if they're not, will immediately point the way to
-where this is violated.
-
-Occasionally, however, this may not be enough. This is because in some
-cases, a C3 ordering can be found (the resolution order is fully
-consistent) that is substantially different from the ad-hoc legacy
-ordering. In such cases, you may find that you get an unexpected value
-returned when adapting one or more objects to an interface. To debug
-this, *also* enable ``ZOPE_INTERFACE_LOG_CHANGED_IRO`` and examine the
-output. The main thing to look for is changes in the relative
-positions of interfaces for which there are registered adapters.

- # Narf. We may have an inconsistent order (we won't know for
- # sure until we check all the bases). Python cannot create
- # classes like this:
- #
- # class B1:
- # pass
- # class B2(B1):
- # pass
- # class C(B1, B2): # -> TypeError; this is like saying C(B1, B2, B1).
- # pass
- #
- # However, older versions of zope.interface were fine with this order.
- # A good example is ``providedBy(IOError())``. Because of the way
- # ``classImplements`` works, it winds up with ``__bases__`` ==
- # ``[IEnvironmentError, IIOError, IOSError, ]``
- # (on Python 3). But ``IEnvironmentError`` is a base of both ``IIOError``
- # and ``IOSError``. Previously, we would get a resolution order of
- # ``[IIOError, IOSError, IEnvironmentError, IStandardError, IException, Interface]``
- # but the standard Python algorithm would forbid creating that order entirely.
-
- # Unlike Python's MRO, we attempt to resolve the issue. A few
- # heuristics have been tried. One was:
- #
- # Strip off the first (highest priority) base of each direct
- # base one at a time and seeing if we can come to an agreement
- # with the other bases. (We're trying for a partial ordering
- # here.) This often resolves cases (such as the IOSError case
- # above), and frequently produces the same ordering as the
- # legacy MRO did. If we looked at all the highest priority
- # bases and couldn't find any partial ordering, then we strip
- # them *all* out and begin the C3 step again. We take care not
- # to promote a common root over all others.
- #
- # If we only did the first part, stripped off the first
- # element of the first item, we could resolve simple cases.
- # But it tended to fail badly. If we did the whole thing, it
- # could be extremely painful from a performance perspective
- # for deep/wide things like Zope's OFS.SimpleItem.Item. Plus,
- # anytime you get ExtensionClass.Base into the mix, you're
- # likely to wind up in trouble, because it messes with the MRO
- # of classes. Sigh.

-/* We try to define Py_LIMITED_API before including Python.h.
-
- Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
- Py_REF_DEBUG are not defined. This is a best-effort approximation:
- we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
- the same works for the other two macros. Py_DEBUG implies them,
- but not the other way around.
-
- The implementation is messy (issue #350): on Windows, with _MSC_VER,

- In that case, we guess what pyconfig.h will do to the macros above,
- and check our guess after the #include.
-
- Note that on Windows, with CPython 3.x, you need >= 3.5 and virtualenv
- version >= 16.0.0. With older versions of either, you don't get a
- copy of PYTHON3.DLL in the virtualenv. We can't check the version of
- CPython *before* we even include pyconfig.h. ffi.set_source() puts
- a ``#define _CFFI_NO_LIMITED_API'' at the start of this file if it is
- running on Windows < 3.5, as an attempt at fixing it, but that's
- arguably wrong because it may not be the target version of Python.
- Still better than nothing I guess. As another workaround, you can
- remove the definition of Py_LIMITED_API here.

-
-
-``cryptography`` is a package which provides cryptographic recipes and
-primitives to Python developers. Our goal is for it to be your "cryptographic
-standard library". It supports Python 3.7+ and PyPy3 7.3.11+.
-
-``cryptography`` includes both high level recipes and low level interfaces to
-common cryptographic algorithms such as symmetric ciphers, message digests, and
-key derivation functions. For example, to encrypt something with
-``cryptography``'s high level symmetric encryption recipe:
-
-.. code-block:: pycon
-
- >>> from cryptography.fernet import Fernet
- >>> # Put this somewhere safe!
- >>> key = Fernet.generate_key()
- >>> f = Fernet(key)
- >>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
- >>> token
- b'...'
- >>> f.decrypt(token)
- b'A really secret message. Not for prying eyes.'
-
-You can find more information in the `documentation`_.
-
-You can install ``cryptography`` with:
-
-.. code-block:: console
-
- $ pip install cryptography
-
-For full details see `the installation documentation`_.
-
-Discussion
-~~~~~~~~~~
-
-If you run into bugs, you can file them in our `issue tracker`_.
-
-We maintain a `cryptography-dev`_ mailing list for development discussion.
-
-You can also join ``#pyca`` on ``irc.libera.chat`` to ask questions or get
-involved.

- of the NOTICE file are for informational purposes only and
- do not modify the License. You may add Your own attribution
- notices within Derivative Works that You distribute, alongside
- or as an addendum to the NOTICE text from the Work, provided
- that such additional attribution notices cannot be construed
- as modifying the License.
-
- You may add Your own copyright statement to Your modifications and
- may provide additional or different license terms and conditions

- unless required by applicable law (such as deliberate and grossly
- negligent acts) or agreed to in writing, shall any Contributor be
- liable to You for damages, including any direct, indirect, special,
- incidental, or consequential damages of any character arising as a
- result of this License or out of the use or inability to use the
