provide_sorted_batch in core is incorrectly marked with #[cfg(not(no_global_oom_handling))] which prevents core from building with the cfg enabled.

Nothing in core allocates memory (including this function). The cfg gate is incorrect.

The cfg was added by #107191

`provide_sorted_batch` in core is incorrectly marked with
`#[cfg(not(no_global_oom_handling))]` which prevents core
from building with the cfg enabled.

Nothing in core allocates memory including this function, so
the `cfg` gate is incorrect.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

@Ericson2314 @ojeda - Looks like the existing test (https://github.com/rust-lang/rust/blob/409661936f929b254ffc8adb644cf35d1f9765c4/tests/run-make/alloc-no-oom-handling/Makefile) only builds alloc, not core, seems like something that can be improved on?

Definitely @dpaoliello, thanks! Sent #110652.

…m_handling`

`tests/run-make/alloc-no-oom-handling` tests that `alloc` under
`no_global_oom_handling` builds and is warning-free.

Do the same for `core` to prevent issues such as [1].

Add test for warning-free builds of `core` under `no_global_oom_handling`

With the current Rust nightly (2023-06-01 as of this writing), using
`-Zbuild-std` to recompile the `core` and `alloc` crates while enabling
the `no_global_oom_handling` cfg now works properly. Therefore there is
no further need for the `doors_alloc` hack, which involved manually
copying the source for `alloc` and adding it as a Cargo dependency.

It is still not clear what change on the Rust/Cargo end fixed the
bug that previously blocked using `-Zbuild-std` to set the cfg (at the
time, trying to enable the cfg resulted in large numbers of mysterious
"duplicate lang item" errors). Maybe rust-lang/rust#110649 is related.
