Hopefully, most affected crates have run cargo update by now. If not,
I'll explore phasing this out gradually.

Huh. I’m curious. When exactly was this introduced and why?

@ThePuzzlemaker This was introduced in 9a6ea38, as part of #77135. That PR made us preserve the original TokenStream in more cases, making progress towards fixing the longstanding compiler bug #43081.

Unfortunately, this change broke actix-web and actori-web, since they used an older version of syn that was not prepared to handle the None-delimited groups present in the new TokenStream input. As a result, I added this hack to allow those crates to continue to compile, while still allowing us to preserve Spans in the input TokenStream.

However, having the compiler special-case certain filenames is a really awful hack. I'd like to get rid of this as soon as possible - unfortunately, there may be a large number of Cargo.lock files onGitHub that need to be updated.

Sorry about that. A new crater deployment broke a thing. Should be fixed now.

Ping from triage @Aaron1011 : it seems some crates like actix-web 2.0.0 and actix-web 3.0.0 still regresses after this change. What's next steps here?

The actori-web hack was removed entirely, and we are now linting whenver we apply the actix-web hack.
