File handles shouldn't be inheritable in general. `std::process::Command` takes care of making them inheritable when child processes are spawned, and the `CREATE_PROCESS_LOCK` protects against races in that section on Windows. But `File::try_clone` has been creating inheritable file descriptors outside of that lock, which could be leaking into other child processes unintentionally. See also rust-lang#31069 (comment).
ONCE_INIT is deprecated, and so suggesting it as not only being on par with, but before `Once::new` is a bad idea.
Move debug_map assertions after check for err Fixes rust-lang#65231 We have some assertions in `DebugMap` to catch broken implementations of `Debug` that produce malformed entries. These checks don't make sense if formatting fails partway through. This PR moves those assertions to within the `and_then` closures along with the other formatting logic, so they're only checked if the map hasn't failed to format an entry already.
…ichton make File::try_clone produce non-inheritable handles on Windows ~**NOT READY FOR REVIEW.** This PR is currently mainly to trigger CI so that I can see what happens. (Is there a better way to trigger CI?) I don't know whether this change makes sense yet.~ (Edit: @Mark-Simulacrum clarified that CI doesn't currently run on Windows.) --- File handles shouldn't be inheritable in general. `std::process::Command` takes care of making them inheritable when child processes are spawned, and the `CREATE_PROCESS_LOCK` protects against races in that section on Windows.

InterpCx: make memory field public I made this field private forever ago because I thought sealing things might be nice. But with the `memory_mut` getter it doesn't actually seal anything, and it's not like we need to invalidate caches on writes to memory or so. And moreover, having to use the getters leads to some annoying borrow checking interactions. So, let's just make it public (again). r? @oli-obk
Don't recommend ONCE_INIT in std::sync::Once ONCE_INIT is deprecated, and so suggesting it as not only being on par with, but before `Once::new` is a bad idea.
Move syntax::ext to a syntax_expand and refactor some attribute logic Part of rust-lang#65324. r? @petrochenkov
add example for type_name So users of this function could at least expect what its output for current compiler version.
fmt::Write is about string slices, not byte slices No idea why the docs talk about bytes, maybe a copy-paste error?
doc: fix typo in OsStrExt and OsStringExt
