<https://github.com/pytest-dev/pytest-xdist/issues/5>`_)

1.20.0

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

Features
--------

- ``xdist`` now supports tests to log results multiple times, improving
integration with plugins which require it like `pytest-rerunfailures
<https://github.com/gocept/pytest-rerunfailures>`_ and `flaky

- Removal of unnecessary dependency on incorrect version of py. (`105
<https://github.com/pytest-dev/pytest-xdist/issues/105>`_)

- Fix bug in internal event-loop error handler in the master node. This bug

.. towncrier release notes start

1.17.0

------

- fix 124: xdist would mark test as complete after 'call' step. As a result,
xdist could identify the wrong test as failing when test crashes at teardown.
To address this issue, xdist now marks test as complete at teardown.

1.16.0

------

- ``pytest-xdist`` now requires pytest 2.7 or later.

- Add ``worker_id`` attribute in the TestReport

- new hook: ``pytest_xdist_make_scheduler(config, log)``, can return custom tests items
distribution logic implementation. You can take a look at built-in ``LoadScheduling``
and ``EachScheduling`` implementations. Note that required scheduler class public
API may change in next ``pytest-xdist`` versions.

1.15.0

------

- new ``worker_id`` fixture, returns the id of the worker in a test or fixture.
Thanks Jared Hellman for the PR.

- display progress during collection only when in a terminal, similar to pytest 1397 issue.
Thanks Bruno Oliveira for the PR.

- fix internal error message when ``--maxfail`` is used (62, 65).
Thanks Collin RM Stocks and Bryan A. Jones for reports and Bruno Oliveira for the PR.

1.14

----

- new hook: ``pytest_xdist_node_collection_finished(node, ids)``, called when
a worker has finished collection. Thanks Omer Katz for the request and
Bruno Oliveira for the PR.

- fix README display on pypi

- fix 22: xdist now works if the internal tmpdir plugin is disabled.
Thanks Bruno Oliveira for the PR.

- fix 32: xdist now works if looponfail or boxed are disabled.
Thanks Bruno Oliveira for the PR.

1.13.1

-------

- fix a regression -n 0 now disables xdist again

1.13

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

- extended the tox matrix with the supported py.test versions

- split up the plugin into 3 plugin's
to prepare the departure of boxed and looponfail.

looponfail will be a part of core
and forked boxed will be replaced
with a more reliable primitive based on xdist

- conforming with new pytest-2.8 behavior of returning non-zero when all
tests were skipped or deselected.

- new "--max-slave-restart" option that can be used to control maximum
number of times pytest-xdist can restart slaves due to crashes. Thanks to
Anatoly Bubenkov for the report and Bruno Oliveira for the PR.

- release as wheel

- "-n" option now can be set to "auto" for automatic detection of number
of cpus in the host system. Thanks Suloev Dmitry for the PR.

1.12

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

- fix issue594: properly report errors when the test collection
is random.  Thanks Bruno Oliveira.

- some internal test suite adaptation (to become forward
compatible with the upcoming pytest-2.8)

1.11

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

- fix pytest/xdist issue485 (also depends on py-1.4.22):
attach stdout/stderr on --boxed processes that die.

- fix pytest/xdist issue503: make sure that a node has usually
two items to execute to avoid scoped fixtures to be torn down
pre-maturely (fixture teardown/setup is "nextitem" sensitive).
Thanks to Andreas Pelme for bug analysis and failing test.

- restart crashed nodes by internally refactoring setup handling
of nodes.  Also includes better code documentation.
Many thanks to Floris Bruynooghe for the complete PR.

1.10

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

- add glob support for rsyncignores, add command line option to pass
additional rsyncignores. Thanks Anatoly Bubenkov.

- fix pytest issue382 - produce "pytest_runtest_logstart" event again
in master. Thanks Aron Curzon.

- fix pytest issue419 by sending/receiving indices into the test
collection instead of node ids (which are not necessarily unique
for functions parametrized with duplicate values)

- send multiple "to test" indices in one network message to a slave
and improve heuristics for sending chunks where the chunksize
depends on the number of remaining tests rather than fixed numbers.
This reduces the number of master -> node messages (but not the
reverse direction)

1.9

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

- changed LICENSE to MIT

- fix duplicate reported test ids with --looponfailing
(thanks Jeremy Thurgood)

- fix pytest issue41: re-run tests on all file changes, not just
randomly select ones like .py/.c.

- fix pytest issue347: slaves running on top of Python3.2
will set PYTHONDONTWRITEYBTECODE to 1 to avoid import concurrency
bugs.

1.8

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

- fix pytest-issue93 - use the refined pytest-2.2.1 runtestprotocol
interface to perform eager teardowns for test items.

1.7

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

- fix incompatibilities with pytest-2.2.0 (allow multiple
pytest_runtest_logreport reports for a test item)

1.6

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

- terser collection reporting

- fix issue34 - distributed testing with -p plugin now works correctly

- fix race condition in looponfail mode where a concurrent file removal
could cause a crash

1.5

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

- adapt to and require pytest-2.0 changes, rsyncdirs and rsyncignore can now
only be specified in [pytest] sections of ini files, see "py.test -h"
for details.
- major internal refactoring to match the pytest-2.0 event refactoring
- perform test collection always at slave side instead of at the master
- make python2/python3 bridging work, remove usage of pickling
- improve initial reporting by using line-rewriting
- remove all trailing whitespace from source

1.4

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

- perform distributed testing related reporting in the plugin
rather than having dist-related code in the generic py.test
distribution

- depend on execnet-1.0.7 which adds "env1:NAME=value" keys to
gateway specification strings.

- show detailed gateway setup and platform information only when
"-v" or "--verbose" is specified.

1.3

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

- fix --looponfailing - it would not actually run against the fully changed
source tree when initial conftest files load application state.

- adapt for py-1.3.1's new --maxfailure option

1.2

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

- fix issue79: sessionfinish/teardown hooks are now called systematically
on the slave side
- introduce a new data input/output mechanism to allow the master side
to send and receive data from a slave.
- fix race condition in underlying pickling/unpickling handling
- use and require new register hooks facility of py.test>=1.3.0
- require improved execnet>=1.0.6 because of various race conditions
that can arise in xdist testing modes.
- fix some python3 related pickling related race conditions
- fix PyPI description

1.1

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

- fix an indefinite hang which would wait for events although no events
are pending - this happened if items arrive very quickly while
the "reschedule-event" tried unconditionally avoiding a busy-loop
and not schedule new work.

1.0

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

- moved code out of py-1.1.1 into its own plugin
- use a new, faster and more sensible model to do load-balancing
of tests - now no magic "MAXITEMSPERHOST" is needed and load-testing
works effectively even with very few tests.
- cleaned up termination handling
- make -x cause hard killing of test nodes to decrease wait time
until the traceback shows up on first failure


======================
Releasing pytest-xdist
======================

This document describes the steps to make a new ``pytest-xdist`` release.

Version
-------

``master`` should always be green and a potential release candidate. ``pytest-xdist`` follows
semantic versioning, so given that the current version is ``X.Y.Z``, to find the next version number
one needs to look at the ``changelog`` folder:

- If there is any file named ``*.feature``, then we must make a new **minor** release: next
release will be ``X.Y+1.0``.

- Otherwise it is just a **bug fix** release: ``X.Y.Z+1``.


Steps
-----

To publish a new release ``X.Y.Z``, the steps are as follows:

. Create a new branch named ``release-X.Y.Z`` from the latest ``master``.

. Install ``tox`` in a virtualenv::

 $ pip install tox

. Update the necessary files with::

 $ tox -e release -- X.Y.Z

. Commit and push the branch for review.

. Once PR is **green** and **approved**, create and push a tag::

 $ export VERSION=X.Y.Z
 $ git tag v$VERSION release-$VERSION
 $ git push gitgithub.com:pytest-dev/pytest-xdist.git v$VERSION

That will build the package and publish it on ``PyPI`` automatically.
