It seems Cargo generates so much data that the CI will occasionally fail
due to running out of disk space. This change increases the available
disk space by 20GB.
This commit makes passing compile UI tests optional, allowing the CI to
succeed even when UI tests fail. This change was made because UI tests
are highly susceptible to false negatives due to benign rustc compiler
output changes. A failure resulting from such a benign change inhibits
progress in the main branch due to failing PR testing which would have
otherwise passed.
This fixes UI tests on Linux nightly. Without the `rust-src` component,
an error message pointing to the core libraries is not emitted as
expected. Presumably by making the sources available, the compiler has
somewhere to point to.
This commit also re-enables CI failures for the Linux debug target.
This allows us to test all of the "core" crates (and the guide) by
testing the root workspace, and all of the examples by testing in the
examples workspace.
To the Rust teams, Rust's contributors, Rocket's contributors, the
entire Rust and Rocket communities, my colleagues at Stanford and
beyond, and Jeb: thank you all. Sincerely.
To the next ~4 years of Rocket!
Closes#19.
