24.2.0

[hynek]

Highlights

This release adds two handy classes for the cases when you just want to retry a single function/method call:

def do_something_with_url(url, some_kw):
    resp = httpx.get(url)
    resp.raise_for_status()
    ...

rc = stamina.RetryingCaller(attempts=5)

rc(httpx.HTTPError, do_something_with_url, f"https://httpbin.org/status/404", some_kw=42)

# You can also create a caller with a pre-bound exception type:
bound_rc = rc.on(httpx.HTTPError)

bound_rc(do_something_with_url, f"https://httpbin.org/status/404", some_kw=42)

Both rc and bound_rc run:

do_something_with_url(f"https://httpbin.org/status/404", some_kw=42)

Unfortunately, it's not possible to implement this behavior transparently for async, so you have to use AsyncRetryingCaller for async callables.

Full Changelog

Added

• stamina.RetryingCaller and stamina.AsyncRetryingCaller that allow even easier retries of single callables: stamina.RetryingCaller(attempts=5).on(ValueError)(do_something, "foo", bar=42) and stamina.RetryingCaller(attempts=5)(ValueError, do_something, "foo", bar=42) will call do_something("foo", bar=42) and retry on ValueError up to 5 times.

  stamina.RetryingCaller and stamina.AsyncRetryingCaller take the same arguments as stamina.retry(), except for on that can be bound separately.
