0.17.0: Make migrations simpler & safer

Migrations

This version didn't actually add new migrations (but existing migrations were renamed)

A consequence of this, if you're using Django Migrations and ran migrations pre-0.17 is that one of the Django migrations was renamed, which confuses Django. Before running the Migrations for 0.17.0, you're invited to run the following Django code in the Django shell (manage.py shell):

>>> from django.db.migrations.recorder import MigrationRecorder
>>> MigrationRecorder.Migration.objects.filter(app="procrastinate", name="0001_baseline").update(name="0001_initial")

Starting at this release, migrations can be run while the system runs, provided certain conditions are met.
See the migrations doc for more information.

Work on migrations:

• Use underscores in migration script names (#345)
• Document new rules for database migrations (#342)
• Rename SQL migrations (#347)
• Rename migration: wrong index number (#350)
• Django migrations: generate on the fly via import hooks (#340)

Breaking Changes

• Django migrations, see above.
• procrastinate healthchecks now doesn't report the number of jobs anymore. Use procrastinate shell for that.

Miscellaneous

• Adjust badges (#337)
• Rename Job Store > Job Manager (#335)
• Report test workflow success in Check API (#322)
• Don't test the PRs, just test the branches (#348)
• Ignore aiopg warnings that we can't do anything about (#338)
• Remove HealthCheckRunner, simplify healthchecks (#339)

0.13.0: Remove pendulum dependency

Migrations

None

Breaking changes

• Very slight possible breaking change: the code parsing dates when calling procrastinate defer --at=<date> has changed. If you were using ISO8601 strings, nothing changed. If you were using more exotic formats, we think that nothing changed, but we don't have a definitive proof of that, so here's a warning. See https://procrastinate.readthedocs.io/en/stable/howto/schedule.html?highlight=pendulum#from-the-code (#279)

Miscellaneous

• Use python-dateutil to parse date (#279)

0.11.0: Fix race condition, improve resource usage

Migrations

• https://github.com/peopledoc/procrastinate/blob/master/procrastinate/sql/migrations/delta_0.10.0_001_close_fetch_job_race_condition.sql
• https://github.com/peopledoc/procrastinate/blob/master/procrastinate/sql/migrations/delta_0.10.0_002_add_defer_job_function.sql

Breaking changes

• If you created an AiopgConnector with maxsize=0 or 1, it used to change it to 2. Now it won't. 0 should really be avoided. 1 will disable the listen/notify feature. See doc.

Features

• Synchronous programs can now define a Psycopg2Connector() and have real synchronous I/Os, likely to work better with multithreaded programs. See doc. (#237)
• Default log message contains task result. This means you can return <something> in your task to make this <something> appear in your logs (#252)

Bug Fixes

• Close race condition in procrastinate_fetch_job (#231)
