Coverage

--------------------------

- Fix: the PyPI page had broken links to documentation pages, but no longer
does, closing `issue 1566`_.

- Fix: public members of the coverage module are now properly indicated so that
mypy will find them, fixing `issue 1564`_.

--------------------------

- Added a new setting ``[report] exclude_also`` to let you add more exclusions
without overwriting the defaults. Thanks, `Alpha Chen <pull 1557_>`_,
closing `issue 1391`_.

- Added a :meth:`.CoverageData.purge_files` method to remove recorded data for
a particular file. Contributed by `Stephan Deibel <pull 1547_>`_.

- Fix: when reporting commands fail, they will no longer congratulate
themselves with messages like "Wrote XML report to file.xml" before spewing a
traceback about their failure.

- Fix: arguments in the public API that name file paths now accept pathlib.Path
objects. This includes the ``data_file`` and ``config_file`` arguments to
the Coverage constructor and the ``basename`` argument to CoverageData.
Closes `issue 1552`_.

- Fix: In some embedded environments, an IndexError could occur on stop() when
the originating thread exits before completion. This is now fixed, thanks to
`Russell Keith-Magee <pull 1543_>`_, closing `issue 1542`_.

- Added a ``py.typed`` file to announce our type-hintedness. Thanks,
`KotlinIsland <pull 1550_>`_.

--------------------------

- Added: the debug output file can now be specified with ``[run] debug_file``
in the configuration file. Closes `issue 1319`_.

- Performance: fixed a slowdown with dynamic contexts that's been around since
6.4.3. The fix closes `issue 1538`_. Thankfully this doesn't break the
`Cython change`_ that fixed `issue 972`_. Thanks to Mathieu Kniewallner for
the deep investigative work and comprehensive issue report.

- Typing: all product and test code has type annotations.

.. _changes_7-0-5:

--------------------------

- Fix: On Python 3.7, a file with type annotations but no ``from __future__
import annotations`` would be missing statements in the coverage report. This
is now fixed, closing `issue 1524`_.

.. _changes_7-0-4:

--------------------------

- Performance: an internal cache of file names was accidentally disabled,
resulting in sometimes drastic reductions in performance. This is now fixed,
closing `issue 1527`_. Thanks to Ivan Ciuvalschii for the reproducible test
case.

.. _changes_7-0-3:

--------------------------

- Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining
step could fail with ``assert row is not None`` using 7.0.2. This was due to
a race condition that has always been possible and is still possible. In
7.0.1 and before, the error was silently swallowed by the combining code.
Now it will produce a message "Couldn't combine data file" and ignore the
data file as it used to do before 7.0.2. Closes `issue 1522`_.
