There was a problem hiding this comment.
@ehuss wanted to check in with you on this change as I believe you were one of the people concerned about clippy's defaults. correctness seems to have a higher bar than the warn by defaults, so I feel like this would be acceptable and much easier to maintain than trying to copy in all of the "relevant" correctness lints.
The fact that we don't check for `derive_ord_xor_partial_ord ` almost bit us in rust-lang#14663. Instead of just enabling this one lint, I figured it'd be good to audit all of the `deny` by default lints. That is long enough that I was concerned about maintaining it (or bikeshedding which to enable or disable). All `deny` by default lints are `correctness` lints and I figure we could just enable the group. We normally opt-in to individual clippy lints. From what I remember of that conversation, it mostly stems from how liberal clippy is with making a lint `warn` by default. It also makes an unpinned CI more brittle. I figured clippy is more conservative about `deny` by default lints and slower to add them that this is unlikely to be a problem.

What does this PR try to resolve?
The fact that we don't check for
derive_ord_xor_partial_ordalmost bit us in #14663. If we used clippy's default lint levels, this would have been caught automatically.Instead of just enabling this one lint, I figured it'd be good to audit
all of the
denyby default lints.That is long enough that I was concerned about maintaining it (or
bikeshedding which to enable or disable).
All
denyby default lints arecorrectnesslints and I figure wecould just enable the group.
We normally opt-in to individual clippy lints.
From what I remember of that conversation, it mostly stems from how
liberal clippy is with making a lint
warnby default.It also makes an unpinned CI more brittle.
I figured clippy is more conservative about
denyby default lintsand slower to add them that this is unlikely to be a problem.
As for what existing problems this found,
tomlnever uses borrowed strings)mutnessHow should we test and review this PR?
