Highlights

These are some big changes but I think they're worth it: everything that does not depend on Postgres, has been moved into its sibling project bgt1 because they solve real problems and I've run into a use case where I needed fault-tolerant background threads, but didn't want to depend on an (unused) Postgres driver.

This is why it's still officially Beta, despite the code being more than mature. Hope someone(s) build something cool on top of bgt!

Full changelog below!

Full Changelog

Removed

  • The supervision layer moved to the new bgt package, which pgbg now depends on. pgbg.Supervisor, pgbg.Service, pgbg.SupervisedService, pgbg.IntervalOnlyWakeup, pgbg.as_work_factory, pgbg.exceptions.SuppressedCrashError, and the pgbg.typing.Loop, pgbg.typing.Wakeup, pgbg.typing.DoWork, and pgbg.typing.WorkFactory protocols are gone. Import them from bgt instead; their behavior is unchanged.

Added

  • pgbg.sqlalchemy.init_db() that takes a SQLAlchemy Engine or Connection. #1

Changed

  • The service.notified log event is now called service.woken. It fires on any wakeup, not only on notifications.

  • The restart counter is now called bgt_supervisor_restarts_total, because bgt's supervisor drives every loop. The metrics of elected services keep their pgbg_ prefix. Supervision log events now go to the bgt logger; everything else stays on pgbg.
