Pytest-xdist

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

Bug Fixes
---------

- `1071 <https://github.com/pytest-dev/pytest-xdist/issues/1071>`_: Add backward compatibility for deadlock issue with the ``execnet`` new ``main_thread_only`` "execmodel" triggered when pytest-cov accesses rinfo.

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

This release was YANKED due to a regression fixed in 3.6.1.

Features
--------

- `1027 <https://github.com/pytest-dev/pytest-xdist/pull/1027>`_:``pytest-xdist`` workers now always execute the tests in the main thread.
Previously some tests might end up executing in a separate thread other than ``main`` in the workers, due to some internal `execnet`` details. This can cause problems specially with async frameworks where the event loop is running in the ``main`` thread (for example `620 <https://github.com/pytest-dev/pytest-xdist/issues/620>`__).

Bug Fixes
---------

- `1024 <https://github.com/pytest-dev/pytest-xdist/issues/1024>`_: Added proper handling of ``shouldstop`` (such as set by ``--max-fail``) and ``shouldfail`` conditions in workers.
Previously, a worker might have continued executing further tests before the controller could terminate the session.

- `1028 <https://github.com/pytest-dev/pytest-xdist/issues/1028>`_: Fixed compatibility issue between `looponfail` and editable installs.

- `620 <https://github.com/pytest-dev/pytest-xdist/issues/620>`_: Use the new ``main_thread_only`` ``execnet`` "execmodel" so that code which expects to only run in the main thread will now work as expected.

- `937 <https://github.com/pytest-dev/pytest-xdist/issues/937>`_: Fixed a bug where plugin would raise an incompatibility error with ``--pdb`` despite using ``-n0``.


Removals
--------

- `1053 <https://github.com/pytest-dev/pytest-xdist/issues/1053>`_: Dropped support for Python 3.7.

- `1057 <https://github.com/pytest-dev/pytest-xdist/issues/1057>`_: pytest>=7.0.0 is now required.

execnet>=2.1.0 is now required.


Trivial Changes
---------------

- `1020 <https://github.com/pytest-dev/pytest-xdist/issues/1020>`_: pytest-xdist's ``setup.py`` file is removed.

If you relied on this file, e.g. to install pytest using ``setup.py install``,
please see `Why you shouldn't invoke setup.py directly <https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary>`_ for alternatives.

- `1057 <https://github.com/pytest-dev/pytest-xdist/issues/1057>`_: The internals of pytest-xdist are now fully typed. The typing is not exposed yet.

- `996 <https://github.com/pytest-dev/pytest-xdist/issues/996>`_: Adjusted license file format and content to ensure security scanners will identity the license.

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

Features
--------

- `632 <https://github.com/pytest-dev/pytest-xdist/issues/632>`_: ``--dist=loadscope`` now sorts scopes by number of tests to assign largest scopes early -- in many cases this should improve overall test session running time, as there is less chance of a large scope being left to be processed near the end of the session, leaving other workers idle.

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

Features
--------

- `963 <https://github.com/pytest-dev/pytest-xdist/issues/963>`_: Wait for workers to finish reporting when test run stops early.

This makes sure that the results of in-progress tests are displayed.
Previously these reports were being discarded, losing information about the
test run.

- `965 <https://github.com/pytest-dev/pytest-xdist/issues/965>`_: Added support for Python 3.12.

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

Bug Fixes
---------

- `907 <https://github.com/pytest-dev/pytest-xdist/issues/907>`_: Avoid remote calls during startup as ``execnet`` by default does not ensure remote affinity with the
main thread and might accidentally schedule the pytest worker into a non-main thread, which breaks numerous frameworks,
for example ``asyncio``, ``anyio``, ``PyQt/PySide``, etc.

A more safe correction will require thread affinity in ``execnet`` (`pytest-dev/execnet96 <https://github.com/pytest-dev/execnet/issues/96>`__).

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

Features
--------

- `555 <https://github.com/pytest-dev/pytest-xdist/issues/555>`_: Improved progress output when collecting nodes to be less verbose.
