Move `fd` into `std::sys` #139092

thaliaarchi · 2025-03-29T01:39:50Z

Move platform definitions of fd into std::sys, as part of #117276.

Unlike other modules directly under std::sys, this is only available on some platforms and I have not provided a fallback abstraction for unsupported platforms. That is similar to how std::os::fd is gated to only supported platforms.

Also, fix the unsafe_op_in_unsafe_fn lint, which was allowed for the Unix fd impl. Since macro expansions from std::sys::pal::unix::weak trigger this lint, fix it there too.

It'd be best left to another PR, but I think we could even move the Windows Handle code in this module and rename FileDesc to something like Object.

The fix for the CI error is not obvious to me. Miri indeed does not implement readv or writev, but I would have expected an error from that to have been noticed much sooner than now. I didn’t modify any miri gates. Perhaps Miri hardcodes some pal paths?

RalfJung · 2025-03-30T18:29:22Z

Yeah, we skip the pal tests here:

rust/src/bootstrap/mk/Makefile.in

Lines 72 to 81 in fb04372

    
           $(Q)MIRIFLAGS="-Zmiri-disable-isolation" \ 
        
           	$(BOOTSTRAP) miri --stage 2 library/std \ 
        
           	$(BOOTSTRAP_ARGS) \ 
        
           	--no-doc -- \ 
        
           	--skip fs:: --skip net:: --skip process:: --skip sys::pal:: 
        
           $(Q)MIRIFLAGS="-Zmiri-disable-isolation" \ 
        
           	$(BOOTSTRAP) miri --stage 2 library/std \ 
        
           	$(BOOTSTRAP_ARGS) \ 
        
           	--doc -- \ 
        
           	--skip fs:: --skip net:: --skip process:: --skip sys::pal::

So we'll need to come up with a new pattern for this. We already list fs::, maybe just add fd::?

thaliaarchi · 2025-04-05T03:23:32Z

Thanks for the fix, Ralf. I've pushed an update for that and added the failed job as a try-job. Can we do a try run?
