Description

coming from https://github.com/rust-lang/docs.rs/issues/301

Eagerly queue up failed builds from old rustdoc versions when rustdoc is updated, at a lower priority than user requests. For the same reason as before, this lets us try to eagerly rebuild crates that may have failed due to the old rustdoc, while not clogging up the queue for new releases.

now added by me:
I have the feeling (that needs data) that most of the build failures aren't related to rustdoc issues that are fixed with newer versions. This means the impact of this automation might be wasted build time.

Research direction

Start with the linked docs.rs issue #301 and investigate how failed builds and rustdoc updates are currently queued. The payload names no files or tests; the work is done when a measured, agreed approach exists for retrying eligible old failures at lower priority without unnecessarily consuming build capacity.
