lowhaio-retry

Wrapper that retries failed lowhaio HTTP requests. Allows retries of exceptions from failed HTTP requests.

Installation

pip install lowhaio_retry

Usage

The request function returned from lowhaio.Pool must be wrapped with lowhaio_retry.retry, as in the below example. This will retry the request, waiting the specified interval between retries. If the request still fails, the final exception will be bubbled up to client code.

So instead of a request like

from lowhaio import Pool

request, _ = Pool()

body = ...

code, headers, body = await request(
    b'PUT', 'https://example.com/path', body=body,
    headers=((b'content-length', b'1234'),),
)

you can write

from lowhaio import Pool, HttpConnectionError, HttpDataError
from lowhaio_retry import retry

request, _ = Pool()

retriable_request = retry(request,
    exception_intervals=(
        # Seconds to wait after each exception
        (HttpConnectionError, (0, 0, 0)),
        (HttpDataError, (0, 1, 2, 4)),
    ),
)

body = ...

code, headers, body = await retriable_request(
    b'PUT', 'https://example.com/path', body=body,
    headers=((b'content-length', b'1234'),),
)
