When `relative` is set to True, the day, hour, minutes second will be round to the nearest one, however, the original program do not update the microsecond (reset it). As a result, the run-time offset on the microsecond will then be accumulated. For example, given the interval is 15s and relative is set to True 1. 2018-11-27T15:01:30.123236+08:00 2. 2018-11-27T15:01:45.372687+08:00 3. 2018-11-27T15:02:00.712601+08:00 4. 2018-11-27T15:02:15.987720+08:00 5. 2018-11-27T15:02:31.023670+08:00

* Added integration coverage for link_error (#5373) * Added coverage for link_error. * Use pytest-rerunfailed plugin instead of rolling our own custom implementation. * Added link_error with retries. This currently fails. * Remove unused import. * Fix import on Python 2.7. * retries in link_error do not hang the worker anymore. * Run error callbacks eagerly when the task itself is run eagerly. Fixes #4899. * Adjust unit tests accordingly. * Grammar in documentation (#5780) * Grammar in documentation * Address review. * pypy 7.2 matrix (#5790) * removed extra slashes in CELERY_BROKER_URL (#5792) The Celery broker URL in settings.py had 2 slashes in the end which are not required and can be misleading. so I changed :- CELERY_BROKER_URL = 'amqp://guest:guest@localhost//' to CELERY_BROKER_URL = 'amqp://guest:guest@localhost' * Fix #5772 task_default_exchange & task_default_exchange_type not work (#5773) * Fix #5772 task_default_exchange & task_default_exchange_type not work * Add unit test: test_setting_default_exchange * Move default_exchange test to standalone class * Run integration suite with memcached results backend. (#5739) * Fix hanging forever when fetching results from a group(chain(group)) canvas. (#5744) PR #5739 uncovered multiple problems with the cache backend. This PR should resolve one of them. PR #5638 fixed the same test case for our async results backends that support native join. However, it did not fix the test case for sync results backends that support native join. * Fix regression in PR #5681. (#5753) See comment in the diff for details. * Grammatical fix to CONTRIBUTING.rst doc (#5794) * Fix #5734 Celery does not consider authMechanism on mongodb backend URLs (#5795) * Fix #5734 Celery does not consider authMechanism on mongodb backend URLs * Add unit test: test_get_connection_with_authmechanism * Add unit test: test_get_connection_with_authmechanism_no_username * Fix errors in Python 2.7 Remove "," after "**" operator * Revert "Revert "Revert "Added handle of SIGTERM in BaseTask in celery/task.py to prevent kill the task" (#5577)" (#5586)" (#5797) This reverts commit f79894e. * Add Python 3.8 Support (#5785) * Added Python 3.8 to the build matrix. * Ensure a supported tblib version is installed for Python 3.8 and above.

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

Update docs regarding Redis Message Priorities * Update 4.4.0 docs (#5875) * Update 4.4 release changelog * Update whatsnew-4.4 * Update tasks docs * Fix recent tasks doc file update (#5879) * Include renamed Changelog.rst in source releases. (#5880) Changelog.rst was renamed from Changelog in fd023ec but MANIFEST.in was not updated to include the new name. This fixes the file name so Changelog.rst will show up in future source releases again. * Reorganised project_urls and classifiers. (#5884) * Use safequote in SQS Getting Started doc (#5885) * Have appveyor build relevant versions of Python. (#5887) * Have appveyor build relevant and buildable versions of Python. * Appveyor is missing CI requirements to build. * Pin pycurl to version that will build with appveyor (because wheels files exist) * Restrict python 2.7 64 bit version of python-dateutil for parse. * Use is_alive instead of isAlive for Python 3.9 compatibility. (#5898) * Very minor tweak to commen to improve docs (#5900) As discussed here: https://stackoverflow.com/questions/58816271/celery-task-asyncresult-takes-task-id-but-is-documented-to-get-asyncresult-inst this comment seems to flow to a very confusing and misleading piece of documentation here: https://docs.celeryproject.org/en/latest/reference/celery.app.task.html#celery.app.task.Task.AsyncResult * Support configuring schema of a PostgreSQL database (#5910) * Support configuring schema of a PostgreSQL database * Add unit test * Remove blank line * Fix raise issue to make exception message more friendly (#5912) Signed-off-by: Chenyang Yan <[email protected]> * Add progress for retry connections (#5915) This will show current retry progress so it will clear confusion about how many retries will be tried for connecting to broker. Closes #4556 * chg: change xrange to range (#5926) * update docs for json serializer and add note for int keys serialization (#5932) * fix indentation for note block in calling.rst (#5933) * Added links to other issue trackers. (#5939) * Add labels automatically for issues.

(#5945) * Added a default value for retries in worker.strategy. I was facing an issue when adding tasks directly to rabbitmq using pika instead of calling task.apply_async. The issue was the self.retry mechanisum was failing. In app/tasks.py the line `retries = request.retries + 1` was causing the issue. On further tracing I figured out that it was because the default .get value (None) was getting passed through this function and was raising TypeError: unsupported operand type(s) for +: 'NoneType' and 'int' * Add test cases for default and custom retries value * pypy 7.3 (#5980) * Pass `interval` to `get_many` (#5931) * Pass `interval` to `get_many` * Fix: Syntax error for py2.7 * Fix: Syntax error for py2.7 * Fixed problem with conflicting autoretry_for task parameter and Task.replace() (#5934) * Fix #5917 (#5918) * Fix changelog (#5881) * merge in place the apps beat schedule in the default Schedule class. (#5908) * Handle Redis connection errors in result consumer (#5921) * Handle Redis connection errors in result consumer * Closes #5919. * Use context manager for Redis conusmer reconnect * Log error when result backend reconnection fails * Fix inspect_command documentation (#5983) * Use gevent and eventlet wait() functions to remove busy-wait (#5974) * Use gevent and eventlet wait() functions to remove busy-wait Fixes issue #4999. Calling AsyncResult.get() in a gevent context would cause the async Drainer to repeatedly call wait_for until the result was completed. I've updated the code to have a specific implementation for gevent and eventlet that will cause wait_for to only return every "timeout" # of seconds, rather than repeatedly returning. Some things I'd like some feedback on: * Where's the best place to add test coverage for this? It doesn't look like there are any tests that directly exercised the Drainer yet so I would probably look to add some of these to the backends/ unit tests. * The way I did this for the Eventlet interface was to rely on the private _exit_event member of the GreenThread instance; to do this without relying on a private member would require some additional changes to the backend Drainer interface so that we could wait for an eventlet-specific event in wait_for(). I can do this, just wanted to get some feedback before. * Add unit tests for Drainer classes In order for this to work without monkeypatching in the tests, I needed to call sleep(0) to let the gevent/eventlet greenlets to yield control back to the calling thread. I also made the check interval configurable in the drainer so that we didn't need to sleep multiples of 1 second in the tests. * Weaken asserts since they don't pass on CI * Fix eventlet auto-patching DNS resolver module on import By default it looks like "import eventlet" imports the greendns module unless the environment EVENTLET_NO_GREENDNS is set to true. This broke a pymongo test. * Add tests ensuring that the greenlet loop isn't blocked These tests make sure that while drain_events_until is running that other gevent/eventlet concurrency can run. * Clean up tests and make sure they wait for all the threads to stop * Fix chords with chained groups (#5947) * kombu 4.6.8 * update setup * updated version 4.4.1 * Fix: Accept and swallow `kwargs` to handle unexpected keyword arguments * Allow boto to look for credentials in S3Backend * add reference to Rusty Celery * Update document of revoke method in Control class * Fix copy-paste error in result_compression docs * Make 'socket_keepalive' optional variable (#6000) * update connection params - socket_keepalive is optional now * update readme - added versionadded 4.4.1 and fixed `redis_socket_keepalive` * added check of socket_keepalive in arguments for UnixSocketConnect * Fixed incorrect setting name in documentation (#6002) * updated version 4.4.2 * Fix backend utf-8 encoding in s3 backend Celery backend uses utf-8 to deserialize results, which would fail for some serializations like pickle. * Fix typo in celery.bin.multi document * Upgraded pycurl to the latest version that supports wheel. * pytest 5.3.5 max * Add uptime to the stats inspect command * Doc tweaks: mostly grammar and punctuation (#6016) * Fix a bunch of comma splices in the docs * Remove some unnecessary words from next-steps doc * Tweak awkward wording; fix bad em-dash * Fix a bunch more comma splices in next-steps doc * Miscellaneous grammar/punctuation/wording fixes * Link to task options in task decorator docs * Fixing issue #6019: unable to use mysql SSL parameters when getting mysql engine (#6020) * Fixing issue #6019: unable to use mysql SSL parametes in create_engine() * adding test for get_engine when self.forked is False and engine args are passed in for create_engine() * Clean TraceBack to reduce memory leaks for exception task (#6024) * Clean TraceBack to reduce memory leaks * add unit test * add unit test * reject unittest * Patch For Python 2.7 compatibility * update unittest * Register to the garbage collector by explicitly referring to f_locals. * need more check * update code coverage * update Missing unit test * 3.4 -> 3.5 Co-authored-by: heedong.jung <[email protected]> * exceptions: NotRegistered: fix up language Minor fix to the language. * Note about autodiscover_tasks and periodic tasks This is particularly important for Django projects that put periodic tasks into each app's `tasks.py` and want to use one as a periodic task. By the time `autodiscover_tasks()` loads those tasks, the `on_after_configure` Signal has already come and gone, so anything decorated with `@app.on_after_finalize.connect` will never be called. If there's other documentation on this subject, I could not find it. * Avoid PyModulelevel, deprecated in Sphinx 4 Use `PyFunction` instead of `PyModulelevel` to avoid this deprecation warning: RemovedInSphinx40Warning: PyModulelevel is deprecated. Please check the implementation of <class 'celery.contrib.sphinx.TaskDirective'> This replacement is one of the options listed in the Sphinx docs (https://www.sphinx-doc.org/en/master/extdev/deprecated.html). * Give up sending a worker-offline message if transport is not connected (#6039) * If worker-offline event fails to send, give up and die peacefully * Add test for retry= and msgs in heartbeat * Fix the build and all documentation warnings. I finally upgraded our theme to 2.0. As a result we've upgraded Sphinx to 2.0. Work to upgrade Sphinx to 3.0 will proceed in a different PR. This upgrade also fixes our build issues caused by #6032. We don't support Sphinx 1.x as a result of that patch. I've also included the missing 4.3 changelog to our history. * Support both Sphinx 2 and 3. * Add Task to __all__ in celery.__init__.py * Add missing parenthesis to example in docs * Ensure a single chain object in a chain does not raise MaximumRecursionError. Previously chain([chain(sig)]) would crash. We now ensure it doesn't. Fixes #5973. * update setup.py * fix typo missing quote at the end of line * Fix a typo in monitoring doc * update travis * update ubuntu to focal foss 20.04 LTS * Fix autoscale when prefetch_multiplier is 1 * Allow start_worker to function without ping task * Update celeryd.conf Move the directory of the program before the execution of the command/script * Add documentation for "predefined_queue_urls" * [Fix #6074]: Add missing documentation for MongoDB as result backend. * update funding * 🐛 Correctly handle configuring the serializer for always_eager mode. (#6079) * 🐛 Correctly handle configuring the serializer for always_eager mode. options['serializer'] will always exist, because it is initialized from an mattrgetter. Even if unset, it will be present in the options with a value of None. * 🐛 Add a test for new always_eager + task_serializer behavior. * ✏️ Whoops missed a : * Remove doubling of prefetch_count increase when prefetch_multiplier gt 1 (#6081) * try ubuntu focal (#6088) * Fix eager function not returning result after retries. Using apply function does not return correct results after at least one retry because the return value of successive call is not going back to the original caller. * return retry result if not throw and is_eager if throw is false, we would be interested by the result of retry and not the current result which will be an exception. This way it does not break the logic of `raise self.retry` This should be used like `return self.retry(..., throw=False)` in an except statement. * revert formatting change * Add tests for eager retry without throw * update predefined-queues documentation Suggested version of configuration does not work. Additionally I'd like to mention, that `access_key_id` and `secret_access_key` are mandatory fields and not allowing you to go with defaults AWS_* env variables. I can contribute for this variables to be optional Also I'm not sure if security token will apply, could you please advice how to do it? * Fix couchbase version < 3.0.0 as API changed * Remove reference to -O fair in optimizations -O fair was made the default in Celery 4.0 https://docs.celeryproject.org/en/stable/history/whatsnew-4.0.html#ofair-is-now-the-default-scheduling-strategy * pytest ranges * pypy3 * revert to bionic * do not load docs.txt requirements for python 2.7 As it requires Sphinx >= 2.0.0 and there is no such version compatible with python 2.7 * update cassandra travis integration test configuration cassandra:latest docker image changed location of cqlsh program * pin cassandra-driver CI get stuck after all cassandra integration tests * Fix all flake8 lint errors * Fix all pydocstyle lint errors * Fix all configcheck lint errors * Always requeue while worker lost regardless of the redelivered flag (#6103) * #5598 fix, always redelivery while WorkerLostError * fix, change the requeue flag so the task will remain PENDING * Allow relative paths in the filesystem backend (#6070) * Allow relative paths in the filesystem backend * fix order of if statements * [Fixed Issue #6017] --> Added Multi default logfiles and pidfiles paths [Description]: --> Changed the default paths for log files & pid files to be '/var/log/celery' and '/var/run/celery' --> Handled by creating the respective paths if not exist. --> Used os.makedir(path,if_exists=True) [Unit Test Added]: --> .travis.yml - config updated with 'before install'. --> t/unit/apps/test_multi.py - Changed the default log files & pid files paths wherever required. * Avoid race condition due to task duplication. In some circumstances like a network partitioning, some tasks might be duplicated. Sometimes, this lead to a race condition where a lost task overwrites the result of the last successful task in the backend. In order to avoid this race condition we prevent updating the result if it's already in successful state. This fix has been done for KV backends only and therefore won't work with other backends. * adding tests * Exceptions must be old-style classes or derived from BaseException, but here self.result may not subclass of BaseException. * update fund link * Fix windows build (#6104) * do not load memcache nor couchbase lib during windows build those libraries depends on native libraries libcouchbase and libmemcached that are not installed on Appveyor. As only unit tests runs on Appveyor, it should be fine * Add python 3.8 workaround for app trap * skip tests file_descriptor_safety tests on windows AsyncPool is not supported on Windows so Pool does have _fileno_to_outq attribute, making the test fail * Fix crossplatform log and pid files in multi mode it relates to #6017 * Use tox to build and test on windows * remove tox_install_command * drop python 2.7 from windows build * Add encode to meta task in base.py (#5894) * Add encode to base.py meta result Fix bug with impossibility to load None from task meta * Add tests for None.

If this happens, it will block indefinitely pending any chord depending on this task. this change makes document updates safe for concurrent writes. https://www.elastic.co/guide/en/elasticsearch/reference/current/optimistic-concurrency-control.html * backends base get_many pass READY_STATES arg * test backends base get_many pass READY_STATES arg * Add integration tests for Elasticsearch and fix _update * Revert "revert to bionic" This reverts commit 6e09157. * remove jython check * feat(backend): Adds cleanup to ArangoDB backend * Delete Document Known Issue with CONN_MAX_AGE in 4.3 * issue 6108 fix filesystem backend cannot not be serialized by picked (#6120) * issue 6108 fix filesystem backend cannot not be serialized by picked #6108 * issue-6108 fix unit test failure * issue-6108 fix flake8 warning Co-authored-by: Murphy Meng <[email protected]> * kombu==4.6.9 (#6133) * changelog for 4.4.3 * v 4.4.3 * remove un supported classifier * Fix autoretry_for with explicit retry (#6138) * Add tests for eager task retry * Fixes #6135 If autoretry_for is set too broad on Exception, then autoretry may get a Retry if that's the case, rethrow directly instead of wrapping it in another Retry to avoid loosing new args * Use Django DB max age connection setting (fixes #4116) * Add retry on recoverable exception for the backend (#6122) * Add state to KeyValueStoreBackend.set method This way, a backend implementation is able to take decisions based on current state to store meta in case of failures. * Add retry on recoverable exception for the backend acks.late makes celery acknowledge messages only after processing and storing result on the backend. However, in case of backend unreachable, it will shadow a Retry exception and put the task as failed in the backend not retrying the task and acknoledging it on the broker. With this new result_backend_always_retry setting, if the backend exception is recoverable (to be defined per backend implementation), it will retry the backend operation with an exponential backoff. * Make elasticsearch backward compatible with 6.x * Make ES retry storing updates in a better way if existing value in the backend is success, then do nothing. if it is a ready status, then update it only if new value is a ready status as well. else update it. This way, a SUCCESS cannot be overriden so that we do not loose results but any ready state other than success (FAILURE, REVOKED) can be overriden by another ready status (i.e. a SUCCESS) * Add test for value not found in ES backend * Fix random distribution of jitter for exponential backoff random.randrange should be called with the actual so that all numbers have equivalent probability, otherwise maximum value does have a way higher probability of occuring. * fix unit test if extra modules are not present * ElasticSearch: add setting to save meta as json * fix #6136. celery 4.4.3 always trying create /var/run/celery directory (#6142) * fix #6136. celery 4.4.3 always trying create /var/run/celery directory, even if it's not needed. * fix #6136. cleanup * Add task_internal_error signal (#6049) * Add internal_error signal There is no special signal for an out of body error which can be the result of a bad result backend. * Fix syntax error. * Document the task_internal_error signal.

Currently, only ElasticsearchBackend supports this feature. It protects concurrent update to corrupt state in the backend. Existing success cannot be overriden, nor a ready state by a non ready state. i.e. a Retry state cannot override a Success or Failure. As a result, chord_unlock task will not loop forever due to missing ready state on the backend. * added --range-prefix option to `celery multi` (#6180) * added --range-prefix option to `celery multi` Added option for overriding default range prefix when running multiple workers prividing range with `celery multy` command. * covered multi --range-prefix with tests * fixed --range-prefix test * Added as_list function to AsyncResult class (#6179) * Add as_list method to return task IDs as a list * Add a test for as_list method * Add docstring for as_list method * Fix CassandraBackend error in threads or gevent pool (#6147) * Fix CassandraBackend error in threads or gevent pool * remove CassandraBackend.process_cleanup * Add test case * Add test case * Add comments test_as_uri Co-authored-by: baixue <[email protected]> * changelog for v4.4.6 * v4.4.6 * Update Wiki link in "resources" In the page linked below, the link to wiki is outdated.

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error.

(#5945) * Added a default value for retries in worker.strategy. I was facing an issue when adding tasks directly to rabbitmq using pika instead of calling task.apply_async. The issue was the self.retry mechanisum was failing. In app/tasks.py the line `retries = request.retries + 1` was causing the issue.

(#5908) * Handle Redis connection errors in result consumer (#5921) * Handle Redis connection errors in result consumer * Closes #5919. * Use context manager for Redis conusmer reconnect * Log error when result backend reconnection fails * Fix inspect_command documentation (#5983) * Use gevent and eventlet wait() functions to remove busy-wait (#5974) * Use gevent and eventlet wait() functions to remove busy-wait Fixes issue #4999. Calling AsyncResult.get() in a gevent context would cause the async Drainer to repeatedly call wait_for until the result was completed. I've updated the code to have a specific implementation for gevent and eventlet that will cause wait_for to only return every "timeout" # of seconds, rather than repeatedly returning. Some things I'd like some feedback on: * Where's the best place to add test coverage for this? It doesn't look like there are any tests that directly exercised the Drainer yet so I would probably look to add some of these to the backends/ unit tests. * The way I did this for the Eventlet interface was to rely on the private _exit_event member of the GreenThread instance; to do this without relying on a private member would require some additional changes to the backend Drainer interface so that we could wait for an eventlet-specific event in wait_for(). I can do this, just wanted to get some feedback before. * Add unit tests for Drainer classes In order for this to work without monkeypatching in the tests, I needed to call sleep(0) to let the gevent/eventlet greenlets to yield control back to the calling thread. I also made the check interval configurable in the drainer so that we didn't need to sleep multiples of 1 second in the tests. * Weaken asserts since they don't pass on CI * Fix eventlet auto-patching DNS resolver module on import By default it looks like "import eventlet" imports the greendns module unless the environment EVENTLET_NO_GREENDNS is set to true. This broke a pymongo test. * Add tests ensuring that the greenlet loop isn't blocked These tests make sure that while drain_events_until is running that other gevent/eventlet concurrency can run. * Clean up tests and make sure they wait for all the threads to stop * Fix chords with chained groups (#5947) * kombu 4.6.8 * update setup * updated version 4.4.1 * Fix: Accept and swallow `kwargs` to handle unexpected keyword arguments * Allow boto to look for credentials in S3Backend * add reference to Rusty Celery * Update document of revoke method in Control class * Fix copy-paste error in result_compression docs * Make 'socket_keepalive' optional variable (#6000) * update connection params - socket_keepalive is optional now * update readme - added versionadded 4.4.1 and fixed `redis_socket_keepalive` * added check of socket_keepalive in arguments for UnixSocketConnect * Fixed incorrect setting name in documentation (#6002) * updated version 4.4.2 * Fix backend utf-8 encoding in s3 backend Celery backend uses utf-8 to deserialize results, which would fail for some serializations like pickle. * Fix typo in celery.bin.multi document * Upgraded pycurl to the latest version that supports wheel. * pytest 5.3.5 max * Add uptime to the stats inspect command * Doc tweaks: mostly grammar and punctuation (#6016) * Fix a bunch of comma splices in the docs * Remove some unnecessary words from next-steps doc * Tweak awkward wording; fix bad em-dash * Fix a bunch more comma splices in next-steps doc * Miscellaneous grammar/punctuation/wording fixes * Link to task options in task decorator docs * Fixing issue #6019: unable to use mysql SSL parameters when getting mysql engine (#6020) * Fixing issue #6019: unable to use mysql SSL parametes in create_engine() * adding test for get_engine when self.forked is False and engine args are passed in for create_engine() * Clean TraceBack to reduce memory leaks for exception task (#6024) * Clean TraceBack to reduce memory leaks * add unit test * add unit test * reject unittest * Patch For Python 2.7 compatibility * update unittest * Register to the garbage collector by explicitly referring to f_locals. * need more check * update code coverage * update Missing unit test * 3.4 -> 3.5 Co-authored-by: heedong.jung <[email protected]> * exceptions: NotRegistered: fix up language Minor fix to the language. * Note about autodiscover_tasks and periodic tasks This is particularly important for Django projects that put periodic tasks into each app's `tasks.py` and want to use one as a periodic task. By the time `autodiscover_tasks()` loads those tasks, the `on_after_configure` Signal has already come and gone, so anything decorated with `@app.on_after_finalize.connect` will never be called. If there's other documentation on this subject, I could not find it. * Avoid PyModulelevel, deprecated in Sphinx 4 Use `PyFunction` instead of `PyModulelevel` to avoid this deprecation warning: RemovedInSphinx40Warning: PyModulelevel is deprecated. Please check the implementation of <class 'celery.contrib.sphinx.TaskDirective'> This replacement is one of the options listed in the Sphinx docs (https://www.sphinx-doc.org/en/master/extdev/deprecated.html). * Give up sending a worker-offline message if transport is not connected (#6039) * If worker-offline event fails to send, give up and die peacefully * Add test for retry= and msgs in heartbeat * Fix the build and all documentation warnings. I finally upgraded our theme to 2.0. As a result we've upgraded Sphinx to 2.0. Work to upgrade Sphinx to 3.0 will proceed in a different PR. This upgrade also fixes our build issues caused by #6032. We don't support Sphinx 1.x as a result of that patch. I've also included the missing 4.3 changelog to our history. * Support both Sphinx 2 and 3. * Add Task to __all__ in celery.__init__.py * Add missing parenthesis to example in docs * Ensure a single chain object in a chain does not raise MaximumRecursionError.

Using apply function does not return correct results after at least one retry because the return value of successive call is not going back to the original caller. * return retry result if not throw and is_eager if throw is false, we would be interested by the result of retry and not the current result which will be an exception. This way it does not break the logic of `raise self.retry` This should be used like `return self.retry(..., throw=False)` in an except statement. * revert formatting change * Add tests for eager retry without throw * update predefined-queues documentation Suggested version of configuration does not work. Additionally I'd like to mention, that `access_key_id` and `secret_access_key` are mandatory fields and not allowing you to go with defaults AWS_* env variables. I can contribute for this variables to be optional Also I'm not sure if security token will apply, could you please advice how to do it? * Fix couchbase version < 3.0.0 as API changed * Remove reference to -O fair in optimizations -O fair was made the default in Celery 4.0 https://docs.celeryproject.org/en/stable/history/whatsnew-4.0.html#ofair-is-now-the-default-scheduling-strategy * pytest ranges * pypy3 * revert to bionic * do not load docs.txt requirements for python 2.7 As it requires Sphinx >= 2.0.0 and there is no such version compatible with python 2.7 * update cassandra travis integration test configuration cassandra:latest docker image changed location of cqlsh program * pin cassandra-driver CI get stuck after all cassandra integration tests * Fix all flake8 lint errors * Fix all pydocstyle lint errors * Fix all configcheck lint errors * Always requeue while worker lost regardless of the redelivered flag (#6103) * #5598 fix, always redelivery while WorkerLostError * fix, change the requeue flag so the task will remain PENDING * Allow relative paths in the filesystem backend (#6070) * Allow relative paths in the filesystem backend * fix order of if statements * [Fixed Issue #6017] --> Added Multi default logfiles and pidfiles paths [Description]: --> Changed the default paths for log files & pid files to be '/var/log/celery' and '/var/run/celery' --> Handled by creating the respective paths if not exist. --> Used os.makedir(path,if_exists=True) [Unit Test Added]: --> .travis.yml - config updated with 'before install'. --> t/unit/apps/test_multi.py - Changed the default log files & pid files paths wherever required. * Avoid race condition due to task duplication. In some circumstances like a network partitioning, some tasks might be duplicated. Sometimes, this lead to a race condition where a lost task overwrites the result of the last successful task in the backend. In order to avoid this race condition we prevent updating the result if it's already in successful state. This fix has been done for KV backends only and therefore won't work with other backends. * adding tests * Exceptions must be old-style classes or derived from BaseException, but here self.result may not subclass of BaseException. * update fund link * Fix windows build (#6104) * do not load memcache nor couchbase lib during windows build those libraries depends on native libraries libcouchbase and libmemcached that are not installed on Appveyor.

However, in case of backend unreachable, it will shadow a Retry exception and put the task as failed in the backend not retrying the task and acknoledging it on the broker. With this new result_backend_always_retry setting, if the backend exception is recoverable (to be defined per backend implementation), it will retry the backend operation with an exponential backoff. * Make elasticsearch backward compatible with 6.x * Make ES retry storing updates in a better way if existing value in the backend is success, then do nothing. if it is a ready status, then update it only if new value is a ready status as well. else update it.

When `relative` is set to True, the day, hour, minutes second will be round to the nearest one, however, the original program do not update the microsecond (reset it). As a result, the run-time offset on the microsecond will then be accumulated. For example, given the interval is 15s and relative is set to True 1. 2018-11-27T15:01:30.123236+08:00 2. 2018-11-27T15:01:45.372687+08:00 3. 2018-11-27T15:02:00.712601+08:00 4. 2018-11-27T15:02:15.987720+08:00 5. 2018-11-27T15:02:31.023670+08:00

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

(#5945) * Added a default value for retries in worker.strategy. I was facing an issue when adding tasks directly to rabbitmq using pika instead of calling task.apply_async. The issue was the self.retry mechanisum was failing. In app/tasks.py the line `retries = request.retries + 1` was causing the issue. On further tracing I figured out that it was because the default .get value (None) was getting passed through this function and was raising TypeError: unsupported operand type(s) for +: 'NoneType' and 'int' * Add test cases for default and custom retries value * pypy 7.3 (#5980) * Pass `interval` to `get_many` (#5931) * Pass `interval` to `get_many` * Fix: Syntax error for py2.7 * Fix: Syntax error for py2.7 * Fixed problem with conflicting autoretry_for task parameter and Task.replace() (#5934) * Fix #5917 (#5918) * Fix changelog (#5881) * merge in place the apps beat schedule in the default Schedule class. (#5908) * Handle Redis connection errors in result consumer (#5921) * Handle Redis connection errors in result consumer * Closes #5919. * Use context manager for Redis conusmer reconnect * Log error when result backend reconnection fails * Fix inspect_command documentation (#5983) * Use gevent and eventlet wait() functions to remove busy-wait (#5974) * Use gevent and eventlet wait() functions to remove busy-wait Fixes issue #4999. Calling AsyncResult.get() in a gevent context would cause the async Drainer to repeatedly call wait_for until the result was completed. I've updated the code to have a specific implementation for gevent and eventlet that will cause wait_for to only return every "timeout" # of seconds, rather than repeatedly returning. Some things I'd like some feedback on: * Where's the best place to add test coverage for this? It doesn't look like there are any tests that directly exercised the Drainer yet so I would probably look to add some of these to the backends/ unit tests. * The way I did this for the Eventlet interface was to rely on the private _exit_event member of the GreenThread instance; to do this without relying on a private member would require some additional changes to the backend Drainer interface so that we could wait for an eventlet-specific event in wait_for(). I can do this, just wanted to get some feedback before. * Add unit tests for Drainer classes In order for this to work without monkeypatching in the tests, I needed to call sleep(0) to let the gevent/eventlet greenlets to yield control back to the calling thread. I also made the check interval configurable in the drainer so that we didn't need to sleep multiples of 1 second in the tests. * Weaken asserts since they don't pass on CI * Fix eventlet auto-patching DNS resolver module on import By default it looks like "import eventlet" imports the greendns module unless the environment EVENTLET_NO_GREENDNS is set to true. This broke a pymongo test. * Add tests ensuring that the greenlet loop isn't blocked These tests make sure that while drain_events_until is running that other gevent/eventlet concurrency can run. * Clean up tests and make sure they wait for all the threads to stop * Fix chords with chained groups (#5947) * kombu 4.6.8 * update setup * updated version 4.4.1 * Fix: Accept and swallow `kwargs` to handle unexpected keyword arguments * Allow boto to look for credentials in S3Backend * add reference to Rusty Celery * Update document of revoke method in Control class * Fix copy-paste error in result_compression docs * Make 'socket_keepalive' optional variable (#6000) * update connection params - socket_keepalive is optional now * update readme - added versionadded 4.4.1 and fixed `redis_socket_keepalive` * added check of socket_keepalive in arguments for UnixSocketConnect * Fixed incorrect setting name in documentation (#6002) * updated version 4.4.2 * Fix backend utf-8 encoding in s3 backend Celery backend uses utf-8 to deserialize results, which would fail for some serializations like pickle. * Fix typo in celery.bin.multi document * Upgraded pycurl to the latest version that supports wheel. * pytest 5.3.5 max * Add uptime to the stats inspect command * Doc tweaks: mostly grammar and punctuation (#6016) * Fix a bunch of comma splices in the docs * Remove some unnecessary words from next-steps doc * Tweak awkward wording; fix bad em-dash * Fix a bunch more comma splices in next-steps doc * Miscellaneous grammar/punctuation/wording fixes * Link to task options in task decorator docs * Fixing issue #6019: unable to use mysql SSL parameters when getting mysql engine (#6020) * Fixing issue #6019: unable to use mysql SSL parametes in create_engine() * adding test for get_engine when self.forked is False and engine args are passed in for create_engine() * Clean TraceBack to reduce memory leaks for exception task (#6024) * Clean TraceBack to reduce memory leaks * add unit test * add unit test * reject unittest * Patch For Python 2.7 compatibility * update unittest * Register to the garbage collector by explicitly referring to f_locals. * need more check * update code coverage * update Missing unit test * 3.4 -> 3.5 Co-authored-by: heedong.jung <[email protected]> * exceptions: NotRegistered: fix up language Minor fix to the language. * Note about autodiscover_tasks and periodic tasks This is particularly important for Django projects that put periodic tasks into each app's `tasks.py` and want to use one as a periodic task. By the time `autodiscover_tasks()` loads those tasks, the `on_after_configure` Signal has already come and gone, so anything decorated with `@app.on_after_finalize.connect` will never be called. If there's other documentation on this subject, I could not find it. * Avoid PyModulelevel, deprecated in Sphinx 4 Use `PyFunction` instead of `PyModulelevel` to avoid this deprecation warning: RemovedInSphinx40Warning: PyModulelevel is deprecated. Please check the implementation of <class 'celery.contrib.sphinx.TaskDirective'> This replacement is one of the options listed in the Sphinx docs (https://www.sphinx-doc.org/en/master/extdev/deprecated.html). * Give up sending a worker-offline message if transport is not connected (#6039) * If worker-offline event fails to send, give up and die peacefully * Add test for retry= and msgs in heartbeat * Fix the build and all documentation warnings. I finally upgraded our theme to 2.0. As a result we've upgraded Sphinx to 2.0. Work to upgrade Sphinx to 3.0 will proceed in a different PR. This upgrade also fixes our build issues caused by #6032. We don't support Sphinx 1.x as a result of that patch. I've also included the missing 4.3 changelog to our history. * Support both Sphinx 2 and 3. * Add Task to __all__ in celery.__init__.py * Add missing parenthesis to example in docs * Ensure a single chain object in a chain does not raise MaximumRecursionError. Previously chain([chain(sig)]) would crash. We now ensure it doesn't.

(#6079) * 🐛 Correctly handle configuring the serializer for always_eager mode. options['serializer'] will always exist, because it is initialized from an mattrgetter. Even if unset, it will be present in the options with a value of None. * 🐛 Add a test for new always_eager + task_serializer behavior. * ✏️ Whoops missed a : * Remove doubling of prefetch_count increase when prefetch_multiplier gt 1 (#6081) * try ubuntu focal (#6088) * Fix eager function not returning result after retries. Using apply function does not return correct results after at least one retry because the return value of successive call is not going back to the original caller. * return retry result if not throw and is_eager if throw is false, we would be interested by the result of retry and not the current result which will be an exception. This way it does not break the logic of `raise self.retry` This should be used like `return self.retry(..., throw=False)` in an except statement. * revert formatting change * Add tests for eager retry without throw * update predefined-queues documentation Suggested version of configuration does not work. Additionally I'd like to mention, that `access_key_id` and `secret_access_key` are mandatory fields and not allowing you to go with defaults AWS_* env variables. I can contribute for this variables to be optional Also I'm not sure if security token will apply, could you please advice how to do it? * Fix couchbase version < 3.0.0 as API changed * Remove reference to -O fair in optimizations -O fair was made the default in Celery 4.0 https://docs.celeryproject.org/en/stable/history/whatsnew-4.0.html#ofair-is-now-the-default-scheduling-strategy * pytest ranges * pypy3 * revert to bionic * do not load docs.txt requirements for python 2.7 As it requires Sphinx >= 2.0.0 and there is no such version compatible with python 2.7 * update cassandra travis integration test configuration cassandra:latest docker image changed location of cqlsh program * pin cassandra-driver CI get stuck after all cassandra integration tests * Fix all flake8 lint errors * Fix all pydocstyle lint errors * Fix all configcheck lint errors * Always requeue while worker lost regardless of the redelivered flag (#6103) * #5598 fix, always redelivery while WorkerLostError * fix, change the requeue flag so the task will remain PENDING * Allow relative paths in the filesystem backend (#6070) * Allow relative paths in the filesystem backend * fix order of if statements * [Fixed Issue #6017] --> Added Multi default logfiles and pidfiles paths [Description]: --> Changed the default paths for log files & pid files to be '/var/log/celery' and '/var/run/celery' --> Handled by creating the respective paths if not exist. --> Used os.makedir(path,if_exists=True) [Unit Test Added]: --> .travis.yml - config updated with 'before install'. --> t/unit/apps/test_multi.py - Changed the default log files & pid files paths wherever required. * Avoid race condition due to task duplication. In some circumstances like a network partitioning, some tasks might be duplicated. Sometimes, this lead to a race condition where a lost task overwrites the result of the last successful task in the backend. In order to avoid this race condition we prevent updating the result if it's already in successful state. This fix has been done for KV backends only and therefore won't work with other backends. * adding tests * Exceptions must be old-style classes or derived from BaseException, but here self.result may not subclass of BaseException. * update fund link * Fix windows build (#6104) * do not load memcache nor couchbase lib during windows build those libraries depends on native libraries libcouchbase and libmemcached that are not installed on Appveyor.

As a result, the run-time offset on the microsecond will then be accumulated. For example, given the interval is 15s and relative is set to True 1. 2018-11-27T15:01:30.123236+08:00 2. 2018-11-27T15:01:45.372687+08:00 3. 2018-11-27T15:02:00.712601+08:00 4. 2018-11-27T15:02:15.987720+08:00 5. 2018-11-27T15:02:31.023670+08:00 * Change backend _ensure_not_eager error to warning * Add priority support for 'celery.chord_unlock' task (#5766) * Change eager retry behaviour even with raise self.retry, it should return the eventual value or MaxRetriesExceededError. if return value of eager apply is Retry exception, retry eagerly the task signature * Order supported Python versions * Avoid race condition in elasticsearch backend if a task is retried, the task retry may work concurrently to current task. store_result may come out of order. it may cause a non ready state (Retry) to override a ready state (Success, Failure).

With this new result_backend_always_retry setting, if the backend exception is recoverable (to be defined per backend implementation), it will retry the backend operation with an exponential backoff. * Make elasticsearch backward compatible with 6.x * Make ES retry storing updates in a better way if existing value in the backend is success, then do nothing. if it is a ready status, then update it only if new value is a ready status as well. else update it. This way, a SUCCESS cannot be overriden so that we do not loose results but any ready state other than success (FAILURE, REVOKED) can be overriden by another ready status (i.e. a SUCCESS) * Add test for value not found in ES backend * Fix random distribution of jitter for exponential backoff random.randrange should be called with the actual so that all numbers have equivalent probability, otherwise maximum value does have a way higher probability of occuring. * fix unit test if extra modules are not present * ElasticSearch: add setting to save meta as json * fix #6136. celery 4.4.3 always trying create /var/run/celery directory (#6142) * fix #6136. celery 4.4.3 always trying create /var/run/celery directory, even if it's not needed. * fix #6136. cleanup * Add task_internal_error signal (#6049) * Add internal_error signal There is no special signal for an out of body error which can be the result of a bad result backend. * Fix syntax error. * Document the task_internal_error signal.

Currently, only ElasticsearchBackend supports this feature. It protects concurrent update to corrupt state in the backend. Existing success cannot be overriden, nor a ready state by a non ready state. i.e. a Retry state cannot override a Success or Failure. As a result, chord_unlock task will not loop forever due to missing ready state on the backend. * added --range-prefix option to `celery multi` (#6180) * added --range-prefix option to `celery multi` Added option for overriding default range prefix when running multiple workers prividing range with `celery multy` command. * covered multi --range-prefix with tests * fixed --range-prefix test * Added as_list function to AsyncResult class (#6179) * Add as_list method to return task IDs as a list * Add a test for as_list method * Add docstring for as_list method * Fix CassandraBackend error in threads or gevent pool (#6147) * Fix CassandraBackend error in threads or gevent pool * remove CassandraBackend.process_cleanup * Add test case * Add test case * Add comments test_as_uri Co-authored-by: baixue <[email protected]> * changelog for v4.4.6 * v4.4.6 * Update Wiki link in "resources" In the page linked below, the link to wiki is outdated.

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state. DynamoDB only allows a single TTL update action within a fairly long time window, so some problematic cases (changing the TTL attribute, enabling/disabling TTL when it was recently modified) will raise exceptions that have to be dealt with. * Handle older boto3 versions If the boto3 TTL methods are not found, log an informative error. If the user wants to enable TTL, raise an exception; if TTL should be disabled, simply return. * Improve logging - Handle exceptions by logging the error and re-raising - Log (level debug) when the desired TTL state is already in place * Add and use _has_ttl() convenience method Additional changes: - Handle exceptions when calling boto3's describe_time_to_live() - Fix test cases for missing TTL methods * Update ttl_seconds documentation * Log invalid TTL; catch and raise ValueError * Separate method _get_table_ttl_description * Separate ttl method validation function * Clarify tri-state TTL value * Improve test coverage * Fix minor typo in comment * Mark test as xfail when using the cache backend.

The issue was the self.retry mechanisum was failing. In app/tasks.py the line `retries = request.retries + 1` was causing the issue.

(#5908) * Handle Redis connection errors in result consumer (#5921) * Handle Redis connection errors in result consumer * Closes #5919. * Use context manager for Redis conusmer reconnect * Log error when result backend reconnection fails * Fix inspect_command documentation (#5983) * Use gevent and eventlet wait() functions to remove busy-wait (#5974) * Use gevent and eventlet wait() functions to remove busy-wait Fixes issue #4999. Calling AsyncResult.get() in a gevent context would cause the async Drainer to repeatedly call wait_for until the result was completed. I've updated the code to have a specific implementation for gevent and eventlet that will cause wait_for to only return every "timeout" # of seconds, rather than repeatedly returning. Some things I'd like some feedback on: * Where's the best place to add test coverage for this? It doesn't look like there are any tests that directly exercised the Drainer yet so I would probably look to add some of these to the backends/ unit tests. * The way I did this for the Eventlet interface was to rely on the private _exit_event member of the GreenThread instance; to do this without relying on a private member would require some additional changes to the backend Drainer interface so that we could wait for an eventlet-specific event in wait_for(). I can do this, just wanted to get some feedback before. * Add unit tests for Drainer classes In order for this to work without monkeypatching in the tests, I needed to call sleep(0) to let the gevent/eventlet greenlets to yield control back to the calling thread. I also made the check interval configurable in the drainer so that we didn't need to sleep multiples of 1 second in the tests. * Weaken asserts since they don't pass on CI * Fix eventlet auto-patching DNS resolver module on import By default it looks like "import eventlet" imports the greendns module unless the environment EVENTLET_NO_GREENDNS is set to true. This broke a pymongo test. * Add tests ensuring that the greenlet loop isn't blocked These tests make sure that while drain_events_until is running that other gevent/eventlet concurrency can run. * Clean up tests and make sure they wait for all the threads to stop * Fix chords with chained groups (#5947) * kombu 4.6.8 * update setup * updated version 4.4.1 * Fix: Accept and swallow `kwargs` to handle unexpected keyword arguments * Allow boto to look for credentials in S3Backend * add reference to Rusty Celery * Update document of revoke method in Control class * Fix copy-paste error in result_compression docs * Make 'socket_keepalive' optional variable (#6000) * update connection params - socket_keepalive is optional now * update readme - added versionadded 4.4.1 and fixed `redis_socket_keepalive` * added check of socket_keepalive in arguments for UnixSocketConnect * Fixed incorrect setting name in documentation (#6002) * updated version 4.4.2 * Fix backend utf-8 encoding in s3 backend Celery backend uses utf-8 to deserialize results, which would fail for some serializations like pickle. * Fix typo in celery.bin.multi document * Upgraded pycurl to the latest version that supports wheel. * pytest 5.3.5 max * Add uptime to the stats inspect command * Doc tweaks: mostly grammar and punctuation (#6016) * Fix a bunch of comma splices in the docs * Remove some unnecessary words from next-steps doc * Tweak awkward wording; fix bad em-dash * Fix a bunch more comma splices in next-steps doc * Miscellaneous grammar/punctuation/wording fixes * Link to task options in task decorator docs * Fixing issue #6019: unable to use mysql SSL parameters when getting mysql engine (#6020) * Fixing issue #6019: unable to use mysql SSL parametes in create_engine() * adding test for get_engine when self.forked is False and engine args are passed in for create_engine() * Clean TraceBack to reduce memory leaks for exception task (#6024) * Clean TraceBack to reduce memory leaks * add unit test * add unit test * reject unittest * Patch For Python 2.7 compatibility * update unittest * Register to the garbage collector by explicitly referring to f_locals. * need more check * update code coverage * update Missing unit test * 3.4 -> 3.5 Co-authored-by: heedong.jung <[email protected]> * exceptions: NotRegistered: fix up language Minor fix to the language. * Note about autodiscover_tasks and periodic tasks This is particularly important for Django projects that put periodic tasks into each app's `tasks.py` and want to use one as a periodic task. By the time `autodiscover_tasks()` loads those tasks, the `on_after_configure` Signal has already come and gone, so anything decorated with `@app.on_after_finalize.connect` will never be called. If there's other documentation on this subject, I could not find it. * Avoid PyModulelevel, deprecated in Sphinx 4 Use `PyFunction` instead of `PyModulelevel` to avoid this deprecation warning: RemovedInSphinx40Warning: PyModulelevel is deprecated. Please check the implementation of <class 'celery.contrib.sphinx.TaskDirective'> This replacement is one of the options listed in the Sphinx docs (https://www.sphinx-doc.org/en/master/extdev/deprecated.html). * Give up sending a worker-offline message if transport is not connected (#6039) * If worker-offline event fails to send, give up and die peacefully * Add test for retry= and msgs in heartbeat * Fix the build and all documentation warnings. I finally upgraded our theme to 2.0. As a result we've upgraded Sphinx to 2.0. Work to upgrade Sphinx to 3.0 will proceed in a different PR. This upgrade also fixes our build issues caused by #6032.

Additionally I'd like to mention, that `access_key_id` and `secret_access_key` are mandatory fields and not allowing you to go with defaults AWS_* env variables.

In some circumstances like a network partitioning, some tasks might be duplicated. Sometimes, this lead to a race condition where a lost task overwrites the result of the last successful task in the backend. In order to avoid this race condition we prevent updating the result if it's already in successful state. This fix has been done for KV backends only and therefore won't work with other backends. * adding tests * Exceptions must be old-style classes or derived from BaseException, but here self.result may not subclass of BaseException. * update fund link * Fix windows build (#6104) * do not load memcache nor couchbase lib during windows build those libraries depends on native libraries libcouchbase and libmemcached that are not installed on Appveyor. As only unit tests runs on Appveyor, it should be fine * Add python 3.8 workaround for app trap * skip tests file_descriptor_safety tests on windows AsyncPool is not supported on Windows so Pool does have _fileno_to_outq attribute, making the test fail * Fix crossplatform log and pid files in multi mode it relates to #6017 * Use tox to build and test on windows * remove tox_install_command * drop python 2.7 from windows build * Add encode to meta task in base.py (#5894) * Add encode to base.py meta result Fix bug with impossibility to load None from task meta * Add tests for None. Remove exceed encode. * Update base.py Add return payload if None * Update time.py to solve the microsecond issues (#5199) When `relative` is set to True, the day, hour, minutes second will be round to the nearest one, however, the original program do not update the microsecond (reset it). As a result, the run-time offset on the microsecond will then be accumulated. For example, given the interval is 15s and relative is set to True 1. 2018-11-27T15:01:30.123236+08:00 2. 2018-11-27T15:01:45.372687+08:00 3. 2018-11-27T15:02:00.712601+08:00 4. 2018-11-27T15:02:15.987720+08:00 5. 2018-11-27T15:02:31.023670+08:00 * Change backend _ensure_not_eager error to warning * Add priority support for 'celery.chord_unlock' task (#5766) * Change eager retry behaviour even with raise self.retry, it should return the eventual value or MaxRetriesExceededError. if return value of eager apply is Retry exception, retry eagerly the task signature * Order supported Python versions * Avoid race condition in elasticsearch backend if a task is retried, the task retry may work concurrently to current task. store_result may come out of order. it may cause a non ready state (Retry) to override a ready state (Success, Failure). If this happens, it will block indefinitely pending any chord depending on this task. this change makes document updates safe for concurrent writes. https://www.elastic.co/guide/en/elasticsearch/reference/current/optimistic-concurrency-control.html * backends base get_many pass READY_STATES arg * test backends base get_many pass READY_STATES arg * Add integration tests for Elasticsearch and fix _update * Revert "revert to bionic" This reverts commit 6e091573f2ab0d0989b8d7c26b677c80377c1721. * remove jython check * feat(backend): Adds cleanup to ArangoDB backend * Delete Document Known Issue with CONN_MAX_AGE in 4.3 * issue 6108 fix filesystem backend cannot not be serialized by picked (#6120) * issue 6108 fix filesystem backend cannot not be serialized by picked https://github.com/celery/celery/issues/6108 * issue-6108 fix unit test failure * issue-6108 fix flake8 warning Co-authored-by: Murphy Meng <[email protected]> * kombu==4.6.9 (#6133) * changelog for 4.4.3 * v 4.4.3 * remove un supported classifier * Fix autoretry_for with explicit retry (#6138) * Add tests for eager task retry * Fixes #6135 If autoretry_for is set too broad on Exception, then autoretry may get a Retry if that's the case, rethrow directly instead of wrapping it in another Retry to avoid loosing new args * Use Django DB max age connection setting (fixes #4116) * Add retry on recoverable exception for the backend (#6122) * Add state to KeyValueStoreBackend.set method This way, a backend implementation is able to take decisions based on current state to store meta in case of failures. * Add retry on recoverable exception for the backend acks.late makes celery acknowledge messages only after processing and storing result on the backend. However, in case of backend unreachable, it will shadow a Retry exception and put the task as failed in the backend not retrying the task and acknoledging it on the broker. With this new result_backend_always_retry setting, if the backend exception is recoverable (to be defined per backend implementation), it will retry the backend operation with an exponential backoff. * Make elasticsearch backward compatible with 6.x * Make ES retry storing updates in a better way if existing value in the backend is success, then do nothing. if it is a ready status, then update it only if new value is a ready status as well. else update it. This way, a SUCCESS cannot be overriden so that we do not loose results but any ready state other than success (FAILURE, REVOKED) can be overriden by another ready status (i.e. a SUCCESS) * Add test for value not found in ES backend * Fix random distribution of jitter for exponential backoff random.randrange should be called with the actual so that all numbers have equivalent probability, otherwise maximum value does have a way higher probability of occuring. * fix unit test if extra modules are not present * ElasticSearch: add setting to save meta as json * fix #6136. celery 4.4.3 always trying create /var/run/celery directory (#6142) * fix #6136. celery 4.4.3 always trying create /var/run/celery directory, even if it's not needed. * fix #6136. cleanup * Add task_internal_error signal (#6049) * Add internal_error signal There is no special signal for an out of body error which can be the result of a bad result backend. * Fix syntax error. * Document the task_internal_error signal.

Currently, only ElasticsearchBackend supports this feature. It protects concurrent update to corrupt state in the backend. Existing success cannot be overriden, nor a ready state by a non ready state. i.e. a Retry state cannot override a Success or Failure. As a result, chord_unlock task will not loop forever due to missing ready state on the backend. * added --range-prefix option to `celery multi` (#6180) * added --range-prefix option to `celery multi` Added option for overriding default range prefix when running multiple workers prividing range with `celery multy` command. * covered multi --range-prefix with tests * fixed --range-prefix test * Added as_list function to AsyncResult class (#6179) * Add as_list method to return task IDs as a list * Add a test for as_list method * Add docstring for as_list method * Fix CassandraBackend error in threads or gevent pool (#6147) * Fix CassandraBackend error in threads or gevent pool * remove CassandraBackend.process_cleanup * Add test case * Add test case * Add comments test_as_uri Co-authored-by: baixue <[email protected]> * changelog for v4.4.6 * v4.4.6 * Update Wiki link in "resources" In the page linked below, the link to wiki is outdated.

This works fine with .apply_async(). * Trying to fix flaky tests in ci * fix pydocstyle errors * fix pydocstyle * Drainer tests, put a lower constraint on number of intervals liveness should iterate 10 times per interval while drain_events only once. However, as it may use thread that may be scheduled out of order, we may end up in some situation where liveness and drain_events were called the same amount of time.

Although the change isn't as pretty code-wise, it gets rid of an annoyance for the user. * Add auto expiry for DynamoDB backend (#5805) * Add auto expiry for DynamoDB backend This adds auto-expire support for the DynamoDB backend, via the DynamoDB Time to Live feature. * Require boto3>=1.9.178 for DynamoDB TTL support boto3 version 1.9.178 requires botocore>=1.12.178. botocore version 1.12.178 introduces support for the DynamoDB UpdateTimeToLive call. The UpdateTimeToLive call is used by the DynamoDB backend to enable TTL support on a newly created table. * Separate TTL handling from table creation Handle TTL enabling/disabling separately from the table get-or-create function. Improve handling of cases where the TTL is already set to the desired state.

The issue was the self.retry mechanisum was failing. In app/tasks.py the line `retries = request.retries + 1` was causing the issue.

Calling AsyncResult.get() in a gevent context would cause the async Drainer to repeatedly call wait_for until the result was completed. I've updated the code to have a specific implementation for gevent and eventlet that will cause wait_for to only return every "timeout" # of seconds, rather than repeatedly returning. Some things I'd like some feedback on: * Where's the best place to add test coverage for this? It doesn't look like there are any tests that directly exercised the Drainer yet so I would probably look to add some of these to the backends/ unit tests. * The way I did this for the Eventlet interface was to rely on the private _exit_event member of the GreenThread instance; to do this without relying on a private member would require some additional changes to the backend Drainer interface so that we could wait for an eventlet-specific event in wait_for(). I can do this, just wanted to get some feedback before. * Add unit tests for Drainer classes In order for this to work without monkeypatching in the tests, I needed to call sleep(0) to let the gevent/eventlet greenlets to yield control back to the calling thread. I also made the check interval configurable in the drainer so that we didn't need to sleep multiples of 1 second in the tests. * Weaken asserts since they don't pass on CI * Fix eventlet auto-patching DNS resolver module on import By default it looks like "import eventlet" imports the greendns module unless the environment EVENTLET_NO_GREENDNS is set to true. This broke a pymongo test. * Add tests ensuring that the greenlet loop isn't blocked These tests make sure that while drain_events_until is running that other gevent/eventlet concurrency can run. * Clean up tests and make sure they wait for all the threads to stop * Fix chords with chained groups (#5947) * kombu 4.6.8 * update setup * updated version 4.4.1 * Fix: Accept and swallow `kwargs` to handle unexpected keyword arguments * Allow boto to look for credentials in S3Backend * add reference to Rusty Celery * Update document of revoke method in Control class * Fix copy-paste error in result_compression docs * Make 'socket_keepalive' optional variable (#6000) * update connection params - socket_keepalive is optional now * update readme - added versionadded 4.4.1 and fixed `redis_socket_keepalive` * added check of socket_keepalive in arguments for UnixSocketConnect * Fixed incorrect setting name in documentation (#6002) * updated version 4.4.2 * Fix backend utf-8 encoding in s3 backend Celery backend uses utf-8 to deserialize results, which would fail for some serializations like pickle. * Fix typo in celery.bin.multi document * Upgraded pycurl to the latest version that supports wheel. * pytest 5.3.5 max * Add uptime to the stats inspect command * Doc tweaks: mostly grammar and punctuation (#6016) * Fix a bunch of comma splices in the docs * Remove some unnecessary words from next-steps doc * Tweak awkward wording; fix bad em-dash * Fix a bunch more comma splices in next-steps doc * Miscellaneous grammar/punctuation/wording fixes * Link to task options in task decorator docs * Fixing issue #6019: unable to use mysql SSL parameters when getting mysql engine (#6020) * Fixing issue #6019: unable to use mysql SSL parametes in create_engine() * adding test for get_engine when self.forked is False and engine args are passed in for create_engine() * Clean TraceBack to reduce memory leaks for exception task (#6024) * Clean TraceBack to reduce memory leaks * add unit test * add unit test * reject unittest * Patch For Python 2.7 compatibility * update unittest * Register to the garbage collector by explicitly referring to f_locals. * need more check * update code coverage * update Missing unit test * 3.4 -> 3.5 Co-authored-by: heedong.jung <[email protected]> * exceptions: NotRegistered: fix up language Minor fix to the language. * Note about autodiscover_tasks and periodic tasks This is particularly important for Django projects that put periodic tasks into each app's `tasks.py` and want to use one as a periodic task. By the time `autodiscover_tasks()` loads those tasks, the `on_after_configure` Signal has already come and gone, so anything decorated with `@app.on_after_finalize.connect` will never be called. If there's other documentation on this subject, I could not find it. * Avoid PyModulelevel, deprecated in Sphinx 4 Use `PyFunction` instead of `PyModulelevel` to avoid this deprecation warning: RemovedInSphinx40Warning: PyModulelevel is deprecated. Please check the implementation of <class 'celery.contrib.sphinx.TaskDirective'> This replacement is one of the options listed in the Sphinx docs (https://www.sphinx-doc.org/en/master/extdev/deprecated.html). * Give up sending a worker-offline message if transport is not connected (#6039) * If worker-offline event fails to send, give up and die peacefully * Add test for retry= and msgs in heartbeat * Fix the build and all documentation warnings. I finally upgraded our theme to 2.0. As a result we've upgraded Sphinx to 2.0. Work to upgrade Sphinx to 3.0 will proceed in a different PR. This upgrade also fixes our build issues caused by #6032.

Additionally I'd like to mention, that `access_key_id` and `secret_access_key` are mandatory fields and not allowing you to go with defaults AWS_* env variables. I can contribute for this variables to be optional Also I'm not sure if security token will apply, could you please advice how to do it? * Fix couchbase version < 3.0.0 as API changed * Remove reference to -O fair in optimizations -O fair was made the default in Celery 4.0 https://docs.celeryproject.org/en/stable/history/whatsnew-4.0.html#ofair-is-now-the-default-scheduling-strategy * pytest ranges * pypy3 * revert to bionic * do not load docs.txt requirements for python 2.7 As it requires Sphinx >= 2.0.0 and there is no such version compatible with python 2.7 * update cassandra travis integration test configuration cassandra:latest docker image changed location of cqlsh program * pin cassandra-driver CI get stuck after all cassandra integration tests * Fix all flake8 lint errors * Fix all pydocstyle lint errors * Fix all configcheck lint errors * Always requeue while worker lost regardless of the redelivered flag (#6103) * #5598 fix, always redelivery while WorkerLostError * fix, change the requeue flag so the task will remain PENDING * Allow relative paths in the filesystem backend (#6070) * Allow relative paths in the filesystem backend * fix order of if statements * [Fixed Issue #6017] --> Added Multi default logfiles and pidfiles paths [Description]: --> Changed the default paths for log files & pid files to be '/var/log/celery' and '/var/run/celery' --> Handled by creating the respective paths if not exist. --> Used os.makedir(path,if_exists=True) [Unit Test Added]: --> .travis.yml - config updated with 'before install'. --> t/unit/apps/test_multi.py - Changed the default log files & pid files paths wherever required. * Avoid race condition due to task duplication. In some circumstances like a network partitioning, some tasks might be duplicated. Sometimes, this lead to a race condition where a lost task overwrites the result of the last successful task in the backend. In order to avoid this race condition we prevent updating the result if it's already in successful state. This fix has been done for KV backends only and therefore won't work with other backends. * adding tests * Exceptions must be old-style classes or derived from BaseException, but here self.result may not subclass of BaseException. * update fund link * Fix windows build (#6104) * do not load memcache nor couchbase lib during windows build those libraries depends on native libraries libcouchbase and libmemcached that are not installed on Appveyor. As only unit tests runs on Appveyor, it should be fine * Add python 3.8 workaround for app trap * skip tests file_descriptor_safety tests on windows AsyncPool is not supported on Windows so Pool does have _fileno_to_outq attribute, making the test fail * Fix crossplatform log and pid files in multi mode it relates to #6017 * Use tox to build and test on windows * remove tox_install_command * drop python 2.7 from windows build * Add encode to meta task in base.py (#5894) * Add encode to base.py meta result Fix bug with impossibility to load None from task meta * Add tests for None. Remove exceed encode. * Update base.py Add return payload if None * Update time.py to solve the microsecond issues (#5199) When `relative` is set to True, the day, hour, minutes second will be round to the nearest one, however, the original program do not update the microsecond (reset it). As a result, the run-time offset on the microsecond will then be accumulated. For example, given the interval is 15s and relative is set to True 1. 2018-11-27T15:01:30.123236+08:00 2. 2018-11-27T15:01:45.372687+08:00 3. 2018-11-27T15:02:00.712601+08:00 4. 2018-11-27T15:02:15.987720+08:00 5. 2018-11-27T15:02:31.023670+08:00 * Change backend _ensure_not_eager error to warning * Add priority support for 'celery.chord_unlock' task (#5766) * Change eager retry behaviour even with raise self.retry, it should return the eventual value or MaxRetriesExceededError. if return value of eager apply is Retry exception, retry eagerly the task signature * Order supported Python versions * Avoid race condition in elasticsearch backend if a task is retried, the task retry may work concurrently to current task. store_result may come out of order. it may cause a non ready state (Retry) to override a ready state (Success, Failure). If this happens, it will block indefinitely pending any chord depending on this task. this change makes document updates safe for concurrent writes. https://www.elastic.co/guide/en/elasticsearch/reference/current/optimistic-concurrency-control.html * backends base get_many pass READY_STATES arg * test backends base get_many pass READY_STATES arg * Add integration tests for Elasticsearch and fix _update * Revert "revert to bionic" This reverts commit 6e091573f2ab0d0989b8d7c26b677c80377c1721. * remove jython check * feat(backend): Adds cleanup to ArangoDB backend * Delete Document Known Issue with CONN_MAX_AGE in 4.3 * issue 6108 fix filesystem backend cannot not be serialized by picked (#6120) * issue 6108 fix filesystem backend cannot not be serialized by picked https://github.com/celery/celery/issues/6108 * issue-6108 fix unit test failure * issue-6108 fix flake8 warning Co-authored-by: Murphy Meng <[email protected]> * kombu==4.6.9 (#6133) * changelog for 4.4.3 * v 4.4.3 * remove un supported classifier * Fix autoretry_for with explicit retry (#6138) * Add tests for eager task retry * Fixes #6135 If autoretry_for is set too broad on Exception, then autoretry may get a Retry if that's the case, rethrow directly instead of wrapping it in another Retry to avoid loosing new args * Use Django DB max age connection setting (fixes #4116) * Add retry on recoverable exception for the backend (#6122) * Add state to KeyValueStoreBackend.set method This way, a backend implementation is able to take decisions based on current state to store meta in case of failures. * Add retry on recoverable exception for the backend acks.late makes celery acknowledge messages only after processing and storing result on the backend. However, in case of backend unreachable, it will shadow a Retry exception and put the task as failed in the backend not retrying the task and acknoledging it on the broker. With this new result_backend_always_retry setting, if the backend exception is recoverable (to be defined per backend implementation), it will retry the backend operation with an exponential backoff. * Make elasticsearch backward compatible with 6.x * Make ES retry storing updates in a better way if existing value in the backend is success, then do nothing. if it is a ready status, then update it only if new value is a ready status as well. else update it. This way, a SUCCESS cannot be overriden so that we do not loose results but any ready state other than success (FAILURE, REVOKED) can be overriden by another ready status (i.e. a SUCCESS) * Add test for value not found in ES backend * Fix random distribution of jitter for exponential backoff random.randrange should be called with the actual so that all numbers have equivalent probability, otherwise maximum value does have a way higher probability of occuring. * fix unit test if extra modules are not present * ElasticSearch: add setting to save meta as json * fix #6136. celery 4.4.3 always trying create /var/run/celery directory (#6142) * fix #6136. celery 4.4.3 always trying create /var/run/celery directory, even if it's not needed. * fix #6136. cleanup * Add task_internal_error signal (#6049) * Add internal_error signal There is no special signal for an out of body error which can be the result of a bad result backend. * Fix syntax error. * Document the task_internal_error signal. Co-authored-by: Laurentiu Dragan <[email protected]> * changelog for v4.4.4 * kombu 4.6.10 (#6144) * v4.4.4 * Add missing dependency on future (#6146) Fixes #6145 * ElasticSearch: Retry index if document was deleted between index and update (#6140) * ElasticSearch: Retry index if document was deleted between index and update * Elasticsearch increase coverage to 100% * Fix pydocstyle * Specify minimum version of Sphinx for Celery extension (#6150) The Sphinx extension requires Sphinx 2 or later due to #6032. * fix windows build * fix flake8 error * fix multi tests in local Mock os.mkdir and os.makedirs to avoid creating /var/run/celery and /var/log/celery during unit tests if run without root priviledges * Customize the retry interval of chord_unlock tasks * changelog v4.4.5 * v4.4.5 * Fix typo in comment. * Remove autoscale force_scale methods (#6085) * Remove autoscale force_scale methods * Remove unused variable in test * Pass ping destination to request The destination argument worked fine from CLI but didn't get used when calling ping from Python. * Fix autoscale test * chord: merge init options with run options * put back KeyValueStoreBackend.set method without state It turns out it was breaking some other projects. wrapping set method with _set_with_state, this way it will not break existing Backend. while enabling this feature for other Backend. Currently, only ElasticsearchBackend supports this feature. It protects concurrent update to corrupt state in the backend. Existing success cannot be overriden, nor a ready state by a non ready state. i.e. a Retry state cannot override a Success or Failure. As a result, chord_unlock task will not loop forever due to missing ready state on the backend. * added --range-prefix option to `celery multi` (#6180) * added --range-prefix option to `celery multi` Added option for overriding default range prefix when running multiple workers prividing range with `celery multy` command. * covered multi --range-prefix with tests * fixed --range-prefix test * Added as_list function to AsyncResult class (#6179) * Add as_list method to return task IDs as a list * Add a test for as_list method * Add docstring for as_list method * Fix CassandraBackend error in threads or gevent pool (#6147) * Fix CassandraBackend error in threads or gevent pool * remove CassandraBackend.process_cleanup * Add test case * Add test case * Add comments test_as_uri Co-authored-by: baixue <[email protected]> * changelog for v4.4.6 * v4.4.6 * Update Wiki link in "resources" In the page linked below, the link to wiki is outdated. Fixed that. https://docs.celeryproject.org/en/stable/getting-started/resources.html * test_canvas: Add test for chord-in-chain Add test case for the issue where a chord in a chain does not work when using .apply(). This works fine with .apply_async(). * Trying to fix flaky tests in ci * fix pydocstyle errors * fix pydocstyle * Drainer tests, put a lower constraint on number of intervals liveness should iterate 10 times per interval while drain_events only once. However, as it may use thread that may be scheduled out of order, we may end up in some situation where liveness and drain_events were called the same amount of time. Lowering the constraint from < to <= to avoid failing the tests. * pyupgrade. * Fix merge error.

When
relativeis set to True, the day, hour, minutes second will be round to the nearest one, however, the original program do not update the microsecond (reset it). As a result, the run-time offset on the microsecond will then be accumulated.For example, given the interval is 15s and relative is set to True
When relative is set to True, microsecond offset still accumulate #5198
