* Handle Retry-After by defaultJulian Andres Klode2024-11-181-1/+1
| | | | | | | | | | | | | | Let's get some feedback here. This is capped to 30s per retry, so a maximum of 90s per item that we delay the failure case. In the worst case, we hence have 90n seconds delay for n items. In a more realistic worse case however, the server likely does not collapse per-item, and we end up trying all items in a short burst so it seems more realistic we hit a 90s total delay. The bursty behavior may be suboptimal; we don't quite know, but it seems the specification of Retry-After is per-entity rather than per-host, so technically speaking it seems correct.

| * http: add test for Retry-After handlingFelix Moessbauer2024-11-182-0/+15
| | | | | | | | | | | | | | | | | | | | When enabling Acquire::Retries::HandleRetryAfter, the value of the Retry-After http header is honored and the retry is not executed earlier than this point in time (except if that is longer than the max delay time). The added test checks if the request is delayed at least by the requested time. Signed-off-by: Felix Moessbauer <felix.moessbauer@siemens.com>
| * http: use Retry-After HTTP header to optimize retriesFelix Moessbauer2024-11-186-6/+59
|/ | | | | | | | | | | | | | | | | | | Some mirrors like snapshot.debian.org apply strict http rate limits. While apt already has an exponential backoff mechanism implemented, this is not sufficient due to the following reasons: 1. all retries happen roughly at the same time 2. the retry-after information from the server is not used We fix this by improving the algorithm: First, if present, the timestamp or duration of the Retry-After header is added to the exponential backoff, optimizing for success-on-second-try. Second, a random delay is added (delay += [0, delay]) to distribute the retries to not immediately run into the limit again. To avoid super-long delays, this is capped by the configured maximum delay. This logic only becomes active if the option Acquire::Retries::HandleRetryAfter is enabled.

* string_view: Include missing headersJulian Andres Klode2024-11-171-0/+3
| | | | | | | | | Specifically the lack of the `string_view` include is causing compilation failures for rust-rust-apt. Running iwyu also adds `algorithm` for our use of `std::min`, and `iosfwd` for our use of `std::ostream` none of which seem to be causing build failures so far.
