Highlights

The highlight of this release are without question configurable retry hooks! You can now freely configure functions that are run whenever a retry is scheduled.

Can't wait to see what kind of third-party integrations y'all come up with – please show and tell us!

As a bonus, stamina now also comes with standard library's logging instrumentation out of the box.

If you have praise, comments, or concerns (that aren't outright bugs), head over to the release discussion!

Full Changelog

Added

  • Instrumentation is now pluggable! You can define your own hooks that are run with retry details whenever a retry is scheduled. The documentation now has a whole chapter on instrumentation. #37

  • If structlog is not installed, the scheduled retry is now logged using the standard library logging module by default. #35

Changed

  • Tenacity's internal AttemptManager object is no longer exposed to the user. This was an oversight and never documented. stamina.retry_context() now yields instances of stamina.Attempt. #22

  • Initialization of instrumentation is now delayed. This means that if there's no retries, there's no startup overhead from importing structlog and prometheus-client. #34

  • Some key names in structlog log messages have been renamed to better reflect their meaning (slept → waited_so_far, attempt → retry_num, and error → caused_by). You can rename them back using structlog's structlog.processors.EventRenamer. #35
