Update attrs to 18.2.0 - Githubissues

This PR updates attrs from 17.4.0 to 18.2.0.

Changelog

### 18.2.0 ``` ------------------- Deprecations ^^^^^^^^^^^^ - Comparing subclasses using ``<``, ``>``, ``<=``, and ``>=`` is now deprecated. The docs always claimed that instances are only compared if the types are identical, so this is a first step to conform to the docs. Equality operators (``==`` and ``!=``) were always strict in this regard. `394 <https://github.com/python-attrs/attrs/issues/394>`_ Changes ^^^^^^^ - ``attrs`` now ships its own `PEP 484 <https://www.python.org/dev/peps/pep-0484/>`_ type hints. Together with `mypy <http://mypy-lang.org>`_'s ``attrs`` plugin, you've got all you need for writing statically typed code in both Python 2 and 3! At that occasion, we've also added `narrative docs <https://www.attrs.org/en/stable/types.html>`_ about type annotations in ``attrs``. `238 <https://github.com/python-attrs/attrs/issues/238>`_ - Added *kw_only* arguments to ``attr.ib`` and ``attr.s``, and a corresponding *kw_only* attribute to ``attr.Attribute``. This change makes it possible to have a generated ``__init__`` with keyword-only arguments on Python 3, relaxing the required ordering of default and non-default valued attributes. `281 <https://github.com/python-attrs/attrs/issues/281>`_, `411 <https://github.com/python-attrs/attrs/issues/411>`_ - The test suite now runs with ``hypothesis.HealthCheck.too_slow`` disabled to prevent CI breakage on slower computers. `364 <https://github.com/python-attrs/attrs/issues/364>`_, `396 <https://github.com/python-attrs/attrs/issues/396>`_ - ``attr.validators.in_()`` now raises a ``ValueError`` with a useful message even if the options are a string and the value is not a string. `383 <https://github.com/python-attrs/attrs/issues/383>`_ - ``attr.asdict()`` now properly handles deeply nested lists and dictionaries. `395 <https://github.com/python-attrs/attrs/issues/395>`_ - Added ``attr.converters.default_if_none()`` that allows to replace ``None`` values in attributes. For example ``attr.ib(converter=default_if_none(""))`` replaces ``None`` by empty strings. `400 <https://github.com/python-attrs/attrs/issues/400>`_, `414 <https://github.com/python-attrs/attrs/issues/414>`_ - Fixed a reference leak where the original class would remain live after being replaced when ``slots=True`` is set. `407 <https://github.com/python-attrs/attrs/issues/407>`_ - Slotted classes can now be made weakly referenceable by passing ``attr.s(weakref_slot=True)``. `420 <https://github.com/python-attrs/attrs/issues/420>`_ - Added *cache_hash* option to ``attr.s`` which causes the hash code to be computed once and stored on the object. `425 <https://github.com/python-attrs/attrs/issues/425>`_ - Attributes can be named ``property`` and ``itemgetter`` now. `430 <https://github.com/python-attrs/attrs/issues/430>`_ - It is now possible to override a base class' class variable using only class annotations. `431 <https://github.com/python-attrs/attrs/issues/431>`_ ---- ``` ### 18.1.0 ``` ------------------- Changes ^^^^^^^ - ``x=X(); x.cycle = x; repr(x)`` will no longer raise a ``RecursionError``, and will instead show as ``X(x=...)``. `95 <https://github.com/python-attrs/attrs/issues/95>`_ - ``attr.ib(factory=f)`` is now syntactic sugar for the common case of ``attr.ib(default=attr.Factory(f))``. `178 <https://github.com/python-attrs/attrs/issues/178>`_, `356 <https://github.com/python-attrs/attrs/issues/356>`_ - Added ``attr.field_dict()`` to return an ordered dictionary of ``attrs`` attributes for a class, whose keys are the attribute names. `290 <https://github.com/python-attrs/attrs/issues/290>`_, `349 <https://github.com/python-attrs/attrs/issues/349>`_ - The order of attributes that are passed into ``attr.make_class()`` or the *these* argument of ``attr.s()`` is now retained if the dictionary is ordered (i.e. ``dict`` on Python 3.6 and later, ``collections.OrderedDict`` otherwise). Before, the order was always determined by the order in which the attributes have been defined which may not be desirable when creating classes programatically. `300 <https://github.com/python-attrs/attrs/issues/300>`_, `339 <https://github.com/python-attrs/attrs/issues/339>`_, `343 <https://github.com/python-attrs/attrs/issues/343>`_ - In slotted classes, ``__getstate__`` and ``__setstate__`` now ignore the ``__weakref__`` attribute. `311 <https://github.com/python-attrs/attrs/issues/311>`_, `326 <https://github.com/python-attrs/attrs/issues/326>`_ - Setting the cell type is now completely best effort. This fixes ``attrs`` on Jython. We cannot make any guarantees regarding Jython though, because our test suite cannot run due to dependency incompatabilities. `321 <https://github.com/python-attrs/attrs/issues/321>`_, `334 <https://github.com/python-attrs/attrs/issues/334>`_ - If ``attr.s`` is passed a *these* argument, it will no longer attempt to remove attributes with the same name from the class body. `322 <https://github.com/python-attrs/attrs/issues/322>`_, `323 <https://github.com/python-attrs/attrs/issues/323>`_ - The hash of ``attr.NOTHING`` is now vegan and faster on 32bit Python builds. `331 <https://github.com/python-attrs/attrs/issues/331>`_, `332 <https://github.com/python-attrs/attrs/issues/332>`_ - The overhead of instantiating frozen dict classes is virtually eliminated. `336 <https://github.com/python-attrs/attrs/issues/336>`_ - Generated ``__init__`` methods now have an ``__annotations__`` attribute derived from the types of the fields. `363 <https://github.com/python-attrs/attrs/issues/363>`_ - We have restructured the documentation a bit to account for ``attrs``' growth in scope. Instead of putting everything into the `examples <https://www.attrs.org/en/stable/examples.html>`_ page, we have started to extract narrative chapters. So far, we've added chapters on `initialization <https://www.attrs.org/en/stable/init.html>`_ and `hashing <https://www.attrs.org/en/stable/hashing.html>`_. Expect more to come! `369 <https://github.com/python-attrs/attrs/issues/369>`_, `370 <https://github.com/python-attrs/attrs/issues/370>`_ ---- ```
