Where are these unused unsafe blocks? Can't you add the lint more locally?

I expect it to be this.
Shall it be fixed just for for this use case or also for possible future unsafe-to-safe conversions?
Shall it be fixed by just removing unsafe{}
or by allowing unused_unsafe
selectively?

Please do it selectively, just where we need it. And BTW we'll have to make a 0.18.1 release just for this change.

Why a point release? Shouldn't lint caps hide those errors when nix is used as a crates.io dependency?

What are "lint caps"?

Cargo builds dependencies by calling rustc --cap-lints allow
. This means lints are turned off when building dependencies, so crates work with newer rustc even if they use deny(warnings)
(which would otherwise be a really bad idea, it would basically make it impossible to ever add new lints to rustc).

(rust-lang/libc#1870) Denied lint being overridden instead of unsafe block removed to preserve compatibility with old `libc` versions.

Edited the pull request. Is this this one still needed in face of #1281 which includes similar (but somewhat conflicting) changes? |
@asomers What more to be done for this? |
