Changelog

4.1.0

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

* Updated CI with new Pythons and dependencies.
* Removed rsyncdir support. This makes pytest-cov compatible with xdist 3.0.
Contributed by Sorin Sbarnea in `558 <https://github.com/pytest-dev/pytest-cov/pull/558>`_.
* Optimized summary generation to not be performed if no reporting is active (for example,
when ``--cov-report=''`` is used without ``--cov-fail-under``).
Contributed by Jonathan Stewmon in `589 <https://github.com/pytest-dev/pytest-cov/pull/589>`_.
* Added support for JSON reporting.
Contributed by Matthew Gamble in `582 <https://github.com/pytest-dev/pytest-cov/pull/582>`_.
* Refactored code to use f-strings.
Contributed by Mark Mayo in `572 <https://github.com/pytest-dev/pytest-cov/pull/572>`_.
* Fixed a skip in the test suite for some old xdist.
Contributed by a bunch of people in `565 <https://github.com/pytest-dev/pytest-cov/pull/565>`_.

4.0.0

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

**Note that this release drops support for multiprocessing.**


* `--cov-fail-under` no longer causes `pytest --collect-only` to fail
Contributed by Zac Hatfield-Dodds in `511 <https://github.com/pytest-dev/pytest-cov/pull/511>`_.
* Dropped support for multiprocessing (mostly because `issue 82408 <https://github.com/python/cpython/issues/82408>`_). This feature was
mostly working but very broken in certain scenarios and made the test suite very flaky and slow.

There is builtin multiprocessing support in coverage and you can migrate to that. All you need is this in your
``.coveragerc``::

 [run]
 concurrency = multiprocessing
 parallel = true
 sigterm = true
* Fixed deprecation in ``setup.py`` by trying to import setuptools before distutils.
Contributed by Ben Greiner in `545 <https://github.com/pytest-dev/pytest-cov/pull/545>`_.
* Removed undesirable new lines that were displayed while reporting was disabled.
Contributed by Delgan in `540 <https://github.com/pytest-dev/pytest-cov/pull/540>`_.
* Documentation fixes.
Contributed by Andre Brisco in `543 <https://github.com/pytest-dev/pytest-cov/pull/543>`_
and Colin O'Dell in `525 <https://github.com/pytest-dev/pytest-cov/pull/525>`_.
* Added support for LCOV output format via `--cov-report=lcov`. Only works with coverage 6.3+.
Contributed by Christian Fetzer in `536 <https://github.com/pytest-dev/pytest-cov/issues/536>`_.
* Modernized pytest hook implementation.
Contributed by Bruno Oliveira in `549 <https://github.com/pytest-dev/pytest-cov/pull/549>`_
and Ronny Pfannschmidt in `550 <https://github.com/pytest-dev/pytest-cov/pull/550>`_.

`494 <https://github.com/pytest-dev/pytest-cov/pull/494>`_ and
`495 <https://github.com/pytest-dev/pytest-cov/pull/495>`_.

Contributed by Danilo Šegan in

Contributed by Thomas Grainger in
`477 <https://github.com/pytest-dev/pytest-cov/pull/477>`_.

2.12.1

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

* Changed the `toml` requirement to be always be directly required (instead of being required through a coverage extra).
This fixes issues with pip-compile (`pip-tools1300 <https://github.com/jazzband/pip-tools/issues/1300>`_).
Contributed by Sorin Sbarnea in `472 <https://github.com/pytest-dev/pytest-cov/pull/472>`_.
* Documented ``show_contexts``.
Contributed by Brian Rutledge in `473 <https://github.com/pytest-dev/pytest-cov/pull/473>`_.

2.12.0

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

* Added coverage's `toml` extra to install requirements in setup.py.
Contributed by Christian Riedel in `410 <https://github.com/pytest-dev/pytest-cov/pull/410>`_.
* Fixed ``pytest_cov.__version__`` to have the right value (string with version instead of a string

Contributed by Chris Sreesangkom in `467 <https://github.com/pytest-dev/pytest-cov/pull/467>`_.

Contributed by Terence Honles in `470 <https://github.com/pytest-dev/pytest-cov/pull/470>`_.

2.11.1

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

* Fixed support for newer setuptools (v42+).
Contributed by Michał Górny in `451 <https://github.com/pytest-dev/pytest-cov/pull/451>`_.

2.11.0

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

* Bumped minimum coverage requirement to 5.2.1. This prevents reporting issues.
Contributed by Mateus Berardo de Souza Terra in `433 <https://github.com/pytest-dev/pytest-cov/pull/433>`_.
* Improved sample projects (from the `examples <https://github.com/pytest-dev/pytest-cov/tree/master/examples>`_
directory) to support running `tox -e pyXY`. Now the example configures a suffixed coverage data file,
and that makes the cleanup environment unnecessary.
Contributed by Ganden Schaffner in `435 <https://github.com/pytest-dev/pytest-cov/pull/435>`_.
* Removed the empty `console_scripts` entrypoint that confused some Gentoo build script.
I didn't ask why it was so broken cause I didn't want to ruin my day.
Contributed by Michał Górny in `434 <https://github.com/pytest-dev/pytest-cov/pull/434>`_.
* Fixed the missing `coverage context <https://coverage.readthedocs.io/en/stable/contexts.html>`_
when using subprocesses.
Contributed by Bernát Gábor in `443 <https://github.com/pytest-dev/pytest-cov/pull/443>`_.
* Updated the config section in the docs.
Contributed by Pamela McA'Nulty in `429 <https://github.com/pytest-dev/pytest-cov/pull/429>`_.
* Migrated CI to travis-ci.com (from .org).

2.10.1

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

* Support for ``pytest-xdist`` 2.0, which breaks compatibility with ``pytest-xdist`` before 1.22.3 (from 2017).
Contributed by Zac Hatfield-Dodds in `412 <https://github.com/pytest-dev/pytest-cov/pull/412>`_.
* Fixed the ``LocalPath has no attribute startswith`` failure that occurred when using the ``pytester`` plugin
in inline mode.

2.10.0

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

* Improved the ``--no-cov`` warning. Now it's only shown if ``--no-cov`` is present before ``--cov``.
* Removed legacy pytest support. Changed ``setup.py`` so that ``pytest>=4.6`` is required.

2.9.0

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

* Fixed ``RemovedInPytest4Warning`` when using Pytest 3.10.
Contributed by Michael Manganiello in `354 <https://github.com/pytest-dev/pytest-cov/pull/354>`_.
* Made pytest startup faster when plugin not active by lazy-importing.
Contributed by Anders Hovmöller in `339 <https://github.com/pytest-dev/pytest-cov/pull/339>`_.
* Various CI improvements.
Contributed by Daniel Hahler in `363 <https://github.com/pytest-dev/pytest-cov/pull/>`_ and
`364 <https://github.com/pytest-dev/pytest-cov/pull/364>`_.

`367 <https://github.com/pytest-dev/pytest-cov/pull/367>`_.
* Changed ``--cov-append`` to always enable ``data_suffix`` (a coverage setting).
Contributed by Harm Geerts in
`387 <https://github.com/pytest-dev/pytest-cov/pull/387>`_.
* Changed ``--cov-append`` to handle loading previous data better
(fixes various path aliasing issues).
* Various other testing improvements, github issue templates, example updates.
* Fixed internal failures that are caused by tests that change the current working directory by
ensuring a consistent working directory when coverage is called.
