I tried this:

src/test/ui/fn/issue-80844-no-gate.rs

  fn returns_generator() -> _ {
  //~^ ERROR the type placeholder `_` is not allowed within types on item signatures [E0121]
  //~| NOTE not allowed in type signatures
      || yield 0
      //~^ ERROR yield syntax is experimental
-     //~^ NOTE see issue
+     //~| NOTE see issue
  }
$ ./x.py test src/test/ui/fn

I expected to see this happen: the ui/fn test suite is run, possibly building the testsuite binary using the existing stage 1 rustc.

Instead, this happened: the stage 1 rustc is rebuilt before running the test suite.

This seems to happen randomly; I had rerun the test suite quite a few times using the same command with no issues. This is rather inconvenient since even with 16 logical cores, building rustc takes several minutes and grinds my machine to a halt.

This doesn't just seem to happen when running the test suite, but I'm less confident about saying that rebuilds after modifying rustc's codebase are spurious.

Can you try running with CARGO_LOG=cargo::core::compiler::fingerprint=info and provide a build log when you see a spurious rebuild?

Got one [ended after seeing it was building rustc to spare my poor swap space]:

cc @rust-lang/cargo, any idea on what could be causing the nothing obvious fingerprint error here? Or how to debug it?

It looks like this has to do with:

[2021-01-09T19:04:17Z INFO  cargo::core::compiler::fingerprint] stale: missing "/home/sparkpin/Programming/Rust/rust/build/x86_64-unknown-linux-gnu/stage0-sysroot/lib/rustlib/x86_64-unknown-linux-gnu/lib/libcore-0217996b824fb40a.rmeta"

is this a case where a -Z flag is used to track rlib/rmeta files, and the sysroot files are changing somehow? Are those files indeed missing? Or maybe they're linked in at a later stage of rustbuild?

@Mark-Simulacrum

Hm, yes, we're definitely tracking sysroot files, but they shouldn't be missing - @PatchMixolydic can you check whether those files are actually present? Do you perhaps have something like x.py check running from your editor in the background?

That file does seem to exist. I am running ./x.py check via rust-analyzer, so that may be part of the issue.

I think this is a duplicate of #76661.
