attrs 16.3.0 -> 17.2.0

17.2.0

---

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

none

Deprecations:
^^^^^^^^^^^^^

none

Changes:
^^^^^^^^

• Validators are hashable again.
  Note that validators may become frozen in the future, pending availability of no-overhead frozen classes.
  192 <https://github.com/python-attrs/attrs/issues/192>_

---

17.1.0

---

To encourage more participation, the project has also been moved into a dedicated GitHub organization <https://github.com/python-attrs/>_ and everyone is most welcome to join!

attrs also has a logo now!

.. image:: http://www.attrs.org/en/latest/_static/attrs_logo.png
:alt: attrs logo

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

• attrs will set the __hash__() method to None by default now.
  The way hashes were handled before was in conflict with Python's specification <https://docs.python.org/3/reference/datamodel.htmlobject.__hash__>.
  This may break some software although this breakage is most likely just surfacing of latent bugs.
  You can always make attrs create the __hash__() method using attr.s(hash=True).
  See 136 for the rationale of this change.

.. warning::

Please do not upgrade blindly and do test your software!
Especially if you use instances as dict keys or put them into sets!

• Correspondingly, attr.ib's hash argument is None by default too and mirrors the cmp argument as it should.

Deprecations:
^^^^^^^^^^^^^

• attr.assoc() is now deprecated in favor of attr.evolve() and will stop working in 2018.

Changes:
^^^^^^^^

• Fix default hashing behavior.
  Now hash mirrors the value of cmp and classes are unhashable by default.
  136_
  142 <https://github.com/python-attrs/attrs/issues/142>_
• Added attr.evolve() that, given an instance of an attrs class and field changes as keyword arguments, will instantiate a copy of the given instance with the changes applied.
  evolve() replaces assoc(), which is now deprecated.
  evolve() is significantly faster than assoc(), and requires the class have an initializer that can take the field values as keyword arguments (like attrs itself can generate).
  116 <https://github.com/python-attrs/attrs/issues/116>_
  124 <https://github.com/python-attrs/attrs/pull/124>_
  135 <https://github.com/python-attrs/attrs/pull/135>_
• FrozenInstanceError is now raised when trying to delete an attribute from a frozen class.
  118 <https://github.com/python-attrs/attrs/pull/118>_
• Frozen-ness of classes is now inherited.
  128 <https://github.com/python-attrs/attrs/pull/128>_
• __attrs_post_init__() is now run if validation is disabled.
  130 <https://github.com/python-attrs/attrs/pull/130>_
• Added attr.validators.in_(options) that, given the allowed options, checks whether the attribute value is in it.
  This can be used to check constants, enums, mappings, etc.
  181 <https://github.com/python-attrs/attrs/pull/181>_
• Added attr.validators.and_() that composes multiple validators into one.
  161 <https://github.com/python-attrs/attrs/issues/161>_
• For convenience, the validator argument of attr.s now can take a list of validators that are wrapped using and_().
  138 <https://github.com/python-attrs/attrs/issues/138>_
• Accordingly, attr.validators.optional() now can take a list of validators too.
  161 <https://github.com/python-attrs/attrs/issues/161>_
• Validators can now be defined conveniently inline by using the attribute as a decorator.
  Check out the examples <http://www.attrs.org/en/stable/examples.htmlvalidators>_ to see it in action!
  143 <https://github.com/python-attrs/attrs/issues/143>_
• attr.Factory() now has a takes_self argument that makes the initializer to pass the partially initialized instance into the factory.
  In other words you can define attribute defaults based on other attributes.
  165_
  189 <https://github.com/python-attrs/attrs/issues/189>_
• Default factories can now also be defined inline using decorators.
  They are always passed the partially initialized instance.
  165_
• Conversion can now be made optional using attr.converters.optional().
  105 <https://github.com/python-attrs/attrs/issues/105>_
  173 <https://github.com/python-attrs/attrs/pull/173>_
• attr.make_class() now accepts the keyword argument bases which allows for subclassing.
  152 <https://github.com/python-attrs/attrs/pull/152>_
• Metaclasses are now preserved with slots=True.
  155 <https://github.com/python-attrs/attrs/pull/155>_

17.1.0

---

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

• Removed the deprecated OpenSSL.rand.egd() function.
  Applications should prefer os.urandom() for random number generation.
  630 <https://github.com/pyca/pyopenssl/pull/630>_
• Removed the deprecated default digest argument to OpenSSL.crypto.CRL.export().
  Callers must now always pass an explicit digest.

  X509.set_notAfter(), Revoked.set_rev_date(), Revoked.set_nextUpdate(),
  and Revoked.set_lastUpdate(). You must now pass times in the form
  YYYYMMDDhhmmssZ. YYYYMMDDhhmmss+hhmm and YYYYMMDDhhmmss-hhmm
  will no longer work. 612 <https://github.com/pyca/pyopenssl/pull/612>_

Deprecations:
^^^^^^^^^^^^^

  The names without the "Type"-suffix should be used instead.

Changes:
^^^^^^^^

• Added OpenSSL.crypto.X509.from_cryptography() and OpenSSL.crypto.X509.to_cryptography() for converting X.509 certificate to and from pyca/cryptography objects.
  640 <https://github.com/pyca/pyopenssl/pull/640>_
• Added OpenSSL.crypto.X509Req.from_cryptography(), OpenSSL.crypto.X509Req.to_cryptography(), OpenSSL.crypto.CRL.from_cryptography(), and OpenSSL.crypto.CRL.to_cryptography() for converting X.509 CSRs and CRLs to and from pyca/cryptography objects.
  645 <https://github.com/pyca/pyopenssl/pull/645>_
• Added OpenSSL.debug that allows to get an overview of used library versions (including linked OpenSSL) and other useful runtime information using python -m OpenSSL.debug.
  620 <https://github.com/pyca/pyopenssl/pull/620>_
• Added a fallback path to Context.set_default_verify_paths() to accommodate the upcoming release of cryptography manylinux1 wheels.

pytest 3.0.7 -> 3.1.2

3.1.2

=========================

Bug Fixes

• Required options added via pytest_addoption will no longer prevent using
  --help without passing them. (1999)

• Respect python_files in assertion rewriting. (2121)

• Fix recursion error detection when frames in the traceback contain objects
  that can't be compared (like numpy arrays). (2459)

• UnicodeWarning is issued from the internal pytest warnings plugin only
  when the message contains non-ascii unicode (Python 2 only). (2463)

• Added a workaround for Python 3.6 WindowsConsoleIO breaking due to Pytests's
  FDCapture. Other code using console handles might still be affected by the
  very same issue and might require further workarounds/fixes, i.e. colorama.
  (2467)

Improved Documentation

• Fix internal API links to pluggy objects. (2331)

• Make it clear that pytest.xfail stops test execution at the calling point
  and improve overall flow of the skipping docs. (810)

3.1.1

=========================

Bug Fixes

• pytest warning capture no longer overrides existing warning filters. The
  previous behaviour would override all filters and caused regressions in test
  suites which configure warning filters to match their needs. Note that as a
  side-effect of this is that DeprecationWarning and
  PendingDeprecationWarning are no longer shown by default. (2430)

• Fix issue with non-ascii contents in doctest text files. (2434)

• Fix encoding errors for unicode warnings in Python 2. (2436)

• pytest.deprecated_call now captures PendingDeprecationWarning in
  context manager form. (2441)

Improved Documentation

• Addition of towncrier for changelog management. (2390)

3.1.0

==================

New Features

• The pytest-warnings plugin has been integrated into the core and now pytest automatically
  captures and displays warnings at the end of the test session.

.. warning::

This feature may disrupt test suites which apply and treat warnings themselves, and can be
disabled in your pytest.ini:

.. code-block:: ini

 [pytest]
 addopts = -p no:warnings

See the warnings documentation page <https://docs.pytest.org/en/latest/warnings.html>_ for more
information.

Thanks nicoddemus_ for the PR.

• Added junit_suite_name ini option to specify root <testsuite> name for JUnit XML reports (533_).

• Added an ini option doctest_encoding to specify which encoding to use for doctest files.
  Thanks wheerd_ for the PR (2101_).

• pytest.warns now checks for subclass relationship rather than
  class equality. Thanks lesteve_ for the PR (2166_)

• pytest.raises now asserts that the error message matches a text or regex
  with the match keyword argument. Thanks Kriechi_ for the PR.

• pytest.param can be used to declare test parameter sets with marks and test ids.
  Thanks RonnyPfannschmidt_ for the PR.

Changes

• remove all internal uses of pytest_namespace hooks,
  this is to prepare the removal of preloadconfig in pytest 4.0
  Thanks to RonnyPfannschmidt_ for the PR.

• pytest now warns when a callable ids raises in a parametrized test. Thanks fogo_ for the PR.

• It is now possible to skip test classes from being collected by setting a
  __test__ attribute to False in the class body (2007). Thanks
  to syre for the report and lwm_ for the PR.

• Change junitxml.py to produce reports that comply with Junitxml schema.
  If the same test fails with failure in call and then errors in teardown
  we split testcase element into two, one containing the error and the other
  the failure. (2228) Thanks to kkoukiou for the PR.

• Testcase reports with a url attribute will now properly write this to junitxml.
  Thanks fushi_ for the PR (1874_).

• Remove common items from dict comparision output when verbosity=1. Also update
  the truncation message to make it clearer that pytest truncates all
  assertion messages if verbosity < 2 (1512).
  Thanks mattduck for the PR

• --pdbcls no longer implies --pdb. This makes it possible to use
  addopts=--pdbcls=module.SomeClass on pytest.ini. Thanks davidszotten_ for
  the PR (1952_).

• fix 2013_: turn RecordedWarning into namedtuple,
  to give it a comprehensible repr while preventing unwarranted modification.

• fix 2208_: ensure a iteration limit for pytest.compat.get_real_func.
  Thanks RonnyPfannschmidt for the report and PR.

• Hooks are now verified after collection is complete, rather than right after loading installed plugins. This
  makes it easy to write hooks for plugins which will be loaded during collection, for example using the
  pytest_plugins special variable (1821).
  Thanks nicoddemus for the PR.

• Modify pytest_make_parametrize_id() hook to accept argname as an
  additional parameter.
  Thanks unsignedint_ for the PR.

• Add venv to the default norecursedirs setting.
  Thanks The-Compiler_ for the PR.

• PluginManager.import_plugin now accepts unicode plugin names in Python 2.
  Thanks reutsharabani_ for the PR.

• fix 2308: When using both --lf and --ff, only the last failed tests are run.
  Thanks ojii for the PR.

• Replace minor/patch level version numbers in the documentation with placeholders.
  This significantly reduces change-noise as different contributors regnerate
  the documentation on different platforms.
  Thanks RonnyPfannschmidt_ for the PR.

• fix 2391: consider pytest_plugins on all plugin modules
  Thanks RonnyPfannschmidt for the PR.

Bug Fixes

• Fix AttributeError on sys.stdout.buffer / sys.stderr.buffer
  while using capsys fixture in python 3. (1407).
  Thanks to asottile.

• Change capture.py's DontReadFromInput class to throw io.UnsupportedOperation errors rather
  than ValueErrors in the fileno method (2276).
  Thanks metasyn and vlad-dragos_ for the PR.

• Fix exception formatting while importing modules when the exception message
  contains non-ascii characters (2336).
  Thanks fabioz for the report and nicoddemus_ for the PR.

• Added documentation related to issue (1937)
  Thanks skylarjhdownes for the PR.

• Allow collecting files with any file extension as Python modules (2369).
  Thanks Kodiologist for the PR.

• Show the correct error message when collect "parametrize" func with wrong args (2383).
  Thanks The-Compiler for the report and robin0371_ for the PR.
