- #541: Drop backward-compatibility "slave" aliases related to worker nodes. We deliberately moved away from this terminology years ago, and it seems like the right time to finish the deprecation and removal process.
- #569:
pytest-xdistno longer supports Python 2.7.
- #504: New functions
xdist.is_xdist_worker,xdist.is_xdist_master,xdist.get_xdist_worker_id, to easily identify the current node.
- #471: Fix issue with Rsync reporting in quiet mode.
- #553: When using
-n auto, count the number of physical CPU cores instead of logical ones.
- #541:
pytest-xdistnow requirespytest>=6.0.
- #549: Make
--pdbimply--dist no, as the two options cannot really work together at the moment.
- #478: Fix regression with duplicated arguments via $PYTEST_ADDOPTS in 1.30.0.
- #558: Fix
rsyncdirsusage with pytest 6.0. - #562: Do not trigger the deprecated
pytest_warning_capturedin pytest 6.0+.
- #554: Fix warnings support for upcoming pytest 6.0.
- #548: SCM and CI files are no longer included in the source distribution.
- #475: Drop support for EOL Python 3.4.
- #524: Add testrun_uid fixture. This is a shared value that uniquely identifies a test run among all workers. This also adds a PYTEST_XDIST_TESTRUNUID environment variable that is accessible within a test as well as a command line option --testrunuid to manually set the value from outside.
- #486: Add support for Python 3.8.
- #491: Fix regression that caused custom plugin command-line arguments to be discarded when using
--txmode.
#448: Initialization between workers and master nodes is now more consistent, which fixes a number of long-standing issues related to startup with the
-coption.Issues:
- #6: Poor interaction between
-n#and-c X.cfg - #445: pytest-xdist is not reporting the same nodeid as pytest does
This however only works with pytest 5.1 or later, as it required changes in pytest itself.
- #6: Poor interaction between
- #467: Fix crash issues related to running xdist with the terminal plugin disabled.
- #226:
--max-worker-restartnow assumes a more reasonable value (4 times the number of nodes) when not given explicitly. This prevents test suites from running forever when the suite crashes during collection. - #435: When the test session is interrupted due to running out of workers, the reason is shown in the test summary for easier viewing.
- #442: Compatibility fix for upcoming pytest 5.0:
session.exitstatusis now anIntEnumobject.
- #435: No longer show an internal error when we run out of workers due to crashes.
#426:
pytest-xdistnow uses the newpytest_report_to_serializableandpytest_report_from_serializablehooks frompytest 4.4(still experimental). This will make report serialization more reliable and extensible.This also means that
pytest-xdistnow requirespytest>=4.4.
- #374: The new
pytest_xdist_getremotemodulehook allows overriding the module run on remote nodes. - #415: Improve behavior of
--numprocesses=autoto work well with--pdboption.
- #406: Do not implement deprecated
pytest_logwarninghook in pytest versions where it is deprecated.
#376: The current directory is no longer added
sys.pathfor local workers, only for remote connections.This behavior is surprising because it makes xdist runs and non-xdist runs to potentially behave differently.
- #379: Warning attributes are checked to make sure they can be dumped prior to serializing the warning for submission to the master node.
- #372: Pytest versions older than 3.6 are no longer supported.
- #373: Node setup information is hidden when pytest is run in quiet mode to reduce noise on many-core machines.
#388:
mainargvis made available inworkerinputfrom the host'ssys.argv.This can be used via
request.config.workerinput["mainargv"].
- #332: Fix report of module-level skips (
pytest.skip(reason, allow_module_level=True)). - #378: Fix support for gevent monkeypatching
- #384: pytest 4.1 support:
ExceptionInfoAPI changes. - #390: pytest 4.1 support:
pytest_logwarninghook removed.
- #349: Correctly handle warnings created with arguments that can't be serialized during the transfer from workers to master node.
- #337: New
--maxprocessescommand-line option that limits the maximum number of workers when using--numprocesses=auto.
- #351: Fix scheduling deadlock in case of inter-test locking.
- #344: Fix issue where Warnings could cause pytest to fail if they do not set the args attribute correctly.
- #341: Fix warnings transfer between workers and master node with pytest >= 3.8.
- #330: Improve collection performance by reducing the number of events sent to
masternode.
#321: Revert change that dropped support for
pytest<3.4and requiresix.This change caused problems in some installations, and was a mistaken in the first place as we should not change version requirements in bug-fix releases unless they fix an actual bug.
#305: Remove last references to obsolete
py.code.Remove some unnecessary references to
py.builtin.- #316: Workaround cpu detection on Travis CI.
- Fix issue of virtualized or containerized environments not reporting the number of CPUs correctly. (#9)
- Make all classes subclass from
objectand fixsuper()call inLoadFileScheduling; (#297)
- Add backward compatibility for
slaveoutputattribute toWorkerControllerinstances. (#285)
- Fix issue when using
loadscopeorloadfilewhere tests would fail to start if the first scope had only one test. (#257)
- Change terminology used by

- Add support for the
pytest_runtest_logfinishhook which will be released in pytest 3.4. (#266)
- Drop support for EOL Python 2.6. (#259)

--dist=loadfileoption which load-distributes test to workers grouped by the file the tests live in. (#242)
- Fix accidental mutation of test report during serialization causing longrepr string-ification to break. (#241)
- Fix hang when all worker nodes crash and restart limit is reached (#45)
- Fix issue where the -n option would still run distributed tests when pytest was run with the --collect-only option (#5)
xdistnow supports tests to log results multiple times, improving integration with plugins which require it like pytest-rerunfailures and flaky. (#206 <https://github.com/pytest- dev/pytest-xdist/issues/206>)
- Fix issue where tests were being incorrectly identified if a worker crashed during the
teardownstage of the test. (#124 <https://github.com/pytest- dev/pytest-xdist/issues/124>)
- Fix crash when transferring internal pytest warnings from workers to the master node. (#214 <https://github.com/pytest-dev/pytest- xdist/issues/214>)
--boxedfunctionality has been moved to a separate plugin, pytest-forked. This release now depends onpytest-forkedand provides--boxedas a backward compatibility option. (#1)
- New
--dist=loadscopeoption: sends group of related tests to the same worker. Tests are grouped by module for test functions and by class for test methods. SeeREADME.rstfor more information. (#191 <https://github.com /pytest-dev/pytest-xdist/issues/191>) - Warnings are now properly transferred from workers to the master node. (#92)
- Fix serialization of native tracebacks (
--tb=native). (#196)
- Removal of unnecessary dependency on incorrect version of py. (#105)
- Fix bug in internal event-loop error handler in the master node. This bug would shadow the original errors making extremely hard/impossible for users to diagnose the problem properly. (#175 <https://github.com/pytest- dev/pytest-xdist/issues/175>)
- Fixed serialization of
longrepr.sectionsduring error reporting from workers. (#171) - Fix
ReprLocalnot being unserialized breaking --showlocals usages. (#176)
pytest-xdistnow requirespytest>=3.0.0.
- Add long option --numprocesses as alternative for -n. (#168)
- Fix serialization and deserialization dropping longrepr details. (#133)
- Hot fix release reverting the change introduced by #124, unfortunately it broke a number of test suites so we are reversing this change while we investigate the problem. (#157)
- Introduced
towncrierforCHANGELOGmanagement. (#154) - Added
HOWTORELEASEdocumentation. (#155)
- 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.
pytest-xdistnow requires pytest 2.7 or later.- Add
worker_idattribute 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-inLoadSchedulingandEachSchedulingimplementations. Note that required scheduler class public API may change in nextpytest-xdistversions.
- new
worker_idfixture, 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
--maxfailis used (#62, #65). Thanks Collin RM Stocks and Bryan A. Jones for reports and Bruno Oliveira for the PR.
- 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.
- fix a regression -n 0 now disables xdist again
- 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.
- 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)
- 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.
- 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)
- 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.
- fix pytest-issue93 - use the refined pytest-2.2.1 runtestprotocol interface to perform eager teardowns for test items.
- fix incompatibilities with pytest-2.2.0 (allow multiple pytest_runtest_logreport reports for a test item)
- 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
- 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
- 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.
- 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
- 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
- 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.
- 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
