[dependabot]

Bumps celery from 4.4.7 to 5.1.2.

Release notes

Sourced from celery's releases.

v5.1.2

Release date: 2021-06-28 16.15 P.M UTC+3:00

Release by: Omer Katz

• When chords fail, correctly call errbacks. (#6814)

  We had a special case for calling errbacks when a chord failed which assumed they were old style. This change ensures that we call the proper errback dispatch method which understands new and old style errbacks, and adds test to confirm that things behave as one might expect now.

• Avoid using the Event.isSet() deprecated alias. (#6824)

• Reintroduce sys.argv default behaviour for Celery.start(). (#6825)

v5.1.1

Release date: 2021-06-17 16.10 P.M UTC+3:00

Release by: Omer Katz

• Fix --pool=threads support in command line options parsing. (#6787)

• Fix LoggingProxy.write() return type. (#6791)

• Couchdb key is now always coerced into a string. (#6781)

grp is no longer imported unconditionally. ([#6804](https://github.com/celery/celery/issues/6804))
:   This fixes a regression in 5.1.0 when running Celery in non-unix
systems.

• Ensure regen utility class gets marked as done when concertised. (#6789)

• Preserve call/errbacks of replaced tasks. (#6770)

• Use single-lookahead for regen consumption. (#6799)

• Revoked tasks are no longer incorrectly marked as retried. (#6812, #6816)
