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)

Kudos:

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)
• Make listen/notify optional, through listen_notify=False in your worker configuration (#258)

Bug Fixes

• Close race condition in procrastinate_fetch_job (#231)
• Retry on "server closed connection unexpectedly" errors (#259)
• Synchronous closing for AiopgConnector (#263)
• Add task.defer as an explicit sync method (#257)

0.9.0: Queueing lock

Breaking changes

• Rename PostgresConnector into AiopgConnector (#225):

  The class PostgresConnector became AiopgConnector. The only change is the name.

Migrations

• https://github.com/peopledoc/procrastinate/blob/0.9.0/procrastinate/sql/migrations/delta_0.8.1_001_add_queueing_lock_column.sql

Features

• Add notion of "queueing lock" (#219):

  Queueing locks can ensure periodic jobs do not accumulate in the queue: at any given time, only a single job with a given queueing lock can be waiting.

  See https://procrastinate.readthedocs.io/en/latest/howto/cron.html#launch-a-task-periodically

Documentation

• Fix PostgreSQL docker example in quickstart doc (#230) (Thanks @tmartinfr!)
