This PR updates pytest from 3.9.1 to 4.0.0.

Changelog

4.0.0

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

Removals
--------

- `3737 <https://github.com/pytest-dev/pytest/issues/3737>`_: **RemovedInPytest4Warnings are now errors by default.**

Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type ``RemovedInPytest4Warnings`` now generate errors
instead of warning messages.

**The affected features will be effectively removed in pytest 4.1**, so please consult the
`Deprecations and Removals <https://docs.pytest.org/en/latest/deprecations.html>`__
section in the docs for directions on how to update existing code.

In the pytest ``4.0.X`` series, it is possible to change the errors back into warnings as a stop
gap measure by adding this to your ``pytest.ini`` file:

.. code-block:: ini

   [pytest]
   filterwarnings =
       ignore::pytest.RemovedInPytest4Warning

But this will stop working when pytest ``4.1`` is released.

**If you have concerns** about the removal of a specific feature, please add a
comment to `4348 <https://github.com/pytest-dev/pytest/issues/4348>`__.


- `4358 <https://github.com/pytest-dev/pytest/issues/4358>`_: Remove the ``::()`` notation to denote a test class instance in node ids.

Previously, node ids that contain test instances would use ``::()`` to denote the instance like this::

   test_foo.py::Test::()::test_bar

The extra ``::()`` was puzzling to most users and has been removed, so that the test id becomes now::

   test_foo.py::Test::test_bar

This change could not accompany a deprecation period as is usual when user-facing functionality changes because
it was not really possible to detect when the functionality was being used explicitly.

The extra ``::()`` might have been removed in some places internally already,
which then led to confusion in places where it was expected, e.g. with
``--deselect`` (`4127 <https://github.com/pytest-dev/pytest/issues/4127>`_).

Test class instances are also not listed with ``--collect-only`` anymore.



Features
--------

- `4270 <https://github.com/pytest-dev/pytest/issues/4270>`_: The ``cache_dir`` option uses ``$TOX_ENV_DIR`` as prefix (if set in the environment).

This uses a different cache per tox environment by default.



Bug Fixes
---------

- `3554 <https://github.com/pytest-dev/pytest/issues/3554>`_: Fix ``CallInfo.__repr__`` for when the call is not finished yet.

3.10.1

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

Bug Fixes
---------

- `4287 <https://github.com/pytest-dev/pytest/issues/4287>`_: Fix nested usage of debugging plugin (pdb), e.g. with pytester's ``testdir.runpytest``.


- `4304 <https://github.com/pytest-dev/pytest/issues/4304>`_: Block the ``stepwise`` plugin if ``cacheprovider`` is also blocked, as one depends on the other.


- `4306 <https://github.com/pytest-dev/pytest/issues/4306>`_: Parse ``minversion`` as an actual version and not as dot-separated strings.


- `4310 <https://github.com/pytest-dev/pytest/issues/4310>`_: Fix duplicate collection due to multiple args matching the same packages.


- `4321 <https://github.com/pytest-dev/pytest/issues/4321>`_: Fix ``item.nodeid`` with resolved symlinks.


- `4325 <https://github.com/pytest-dev/pytest/issues/4325>`_: Fix collection of direct symlinked files, where the target does not match ``python_files``.


- `4329 <https://github.com/pytest-dev/pytest/issues/4329>`_: Fix TypeError in report_collect with _collect_report_last_write.



Trivial/Internal Changes
------------------------

- `4305 <https://github.com/pytest-dev/pytest/issues/4305>`_: Replace byte/unicode helpers in test_capture with python level syntax.

3.10.0

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

Features
--------

- `2619 <https://github.com/pytest-dev/pytest/issues/2619>`_: Resume capturing output after ``continue`` with ``__import__("pdb").set_trace()``.

This also adds a new ``pytest_leave_pdb`` hook, and passes in ``pdb`` to the
existing ``pytest_enter_pdb`` hook.


- `4147 <https://github.com/pytest-dev/pytest/issues/4147>`_: Add ``--sw``, ``--stepwise`` as an alternative to ``--lf -x`` for stopping at the first failure, but starting the next test invocation from that test.  See `the documentation <https://docs.pytest.org/en/latest/cache.htmlstepwise>`__ for more info.


- `4188 <https://github.com/pytest-dev/pytest/issues/4188>`_: Make ``--color`` emit colorful dots when not running in verbose mode. Earlier, it would only colorize the test-by-test output if ``--verbose`` was also passed.


- `4225 <https://github.com/pytest-dev/pytest/issues/4225>`_: Improve performance with collection reporting in non-quiet mode with terminals.

The "collecting …" message is only printed/updated every 0.5s.



Bug Fixes
---------

- `2701 <https://github.com/pytest-dev/pytest/issues/2701>`_: Fix false ``RemovedInPytest4Warning: usage of Session... is deprecated, please use pytest`` warnings.


- `4046 <https://github.com/pytest-dev/pytest/issues/4046>`_: Fix problems with running tests in package ``__init__.py`` files.


- `4260 <https://github.com/pytest-dev/pytest/issues/4260>`_: Swallow warnings during anonymous compilation of source.


- `4262 <https://github.com/pytest-dev/pytest/issues/4262>`_: Fix access denied error when deleting stale directories created by ``tmpdir`` / ``tmp_path``.


- `611 <https://github.com/pytest-dev/pytest/issues/611>`_: Naming a fixture ``request`` will now raise a warning: the ``request`` fixture is internal and
should not be overwritten as it will lead to internal errors.

- `4266 <https://github.com/pytest-dev/pytest/issues/4266>`_: Handle (ignore) exceptions raised during collection, e.g. with Django's LazySettings proxy class.



Improved Documentation
----------------------

- `4255 <https://github.com/pytest-dev/pytest/issues/4255>`_: Added missing documentation about the fact that module names passed to filter warnings are not regex-escaped.



Trivial/Internal Changes
------------------------

- `4272 <https://github.com/pytest-dev/pytest/issues/4272>`_: Display cachedir also in non-verbose mode if non-default.


- `4277 <https://github.com/pytest-dev/pytest/issues/4277>`_: pdb: improve message about output capturing with ``set_trace``.

Do not display "IO-capturing turned off/on" when ``-s`` is used to avoid
confusion.


- `4279 <https://github.com/pytest-dev/pytest/issues/4279>`_: Improve message and stack level of warnings issued by ``monkeypatch.setenv`` when the value of the environment variable is not a ``str``.

3.9.3

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

Bug Fixes
---------

- `4174 <https://github.com/pytest-dev/pytest/issues/4174>`_: Fix "ValueError: Plugin already registered" with conftest plugins via symlink.


- `4181 <https://github.com/pytest-dev/pytest/issues/4181>`_: Handle race condition between creation and deletion of temporary folders.


- `4221 <https://github.com/pytest-dev/pytest/issues/4221>`_: Fix bug where the warning summary at the end of the test session was not showing the test where the warning was originated.


- `4243 <https://github.com/pytest-dev/pytest/issues/4243>`_: Fix regression when ``stacklevel`` for warnings was passed as positional argument on python2.



Improved Documentation
----------------------

- `3851 <https://github.com/pytest-dev/pytest/issues/3851>`_: Add reference to ``empty_parameter_set_mark`` ini option in documentation of ``pytest.mark.parametrize``



Trivial/Internal Changes
------------------------

- `4028 <https://github.com/pytest-dev/pytest/issues/4028>`_: Revert patching of ``sys.breakpointhook`` since it appears to do nothing.


- `4233 <https://github.com/pytest-dev/pytest/issues/4233>`_: Apply an import sorter (``reorder-python-imports``) to the codebase.


- `4248 <https://github.com/pytest-dev/pytest/issues/4248>`_: Remove use of unnecessary compat shim, six.binary_type

3.9.2

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

Bug Fixes

- `3340 <https://github.com/pytest-dev/pytest/issues/3340>`_: Fix logging messages not shown in hooks ``pytest_sessionstart()`` and ``pytest_sessionfinish()``.


- `3533 <https://github.com/pytest-dev/pytest/issues/3533>`_: Fix unescaped XML raw objects in JUnit report for skipped tests


- `3691 <https://github.com/pytest-dev/pytest/issues/3691>`_: Python 2: safely format warning message about passing unicode strings to ``warnings.warn``, which may cause
surprising ``MemoryError`` exception when monkey patching ``warnings.warn`` itself.


- `4026 <https://github.com/pytest-dev/pytest/issues/4026>`_: Improve error message when it is not possible to determine a function's signature.
