bors 223d16ebbd Auto merge of #100201 - RalfJung:thread-local-key, r=thomcc ... std: use realstd fast key when building tests Under `cfg(test)`, the `std` crate is not the actual standard library, just any old crate we are testing. It imports the real standard library as `realstd`, and then does some careful `cfg` magic so that the crate built for testing uses the `realstd` global state rather than having its own copy of that. However, this was not done for all global state hidden in std: the 'fast' version of thread-local keys, at least on some platforms, also involves some global state. Specifically its macOS version has this [`static REGISTERED`](bc63d5a26a/library/std/src/sys/unix/thread_local_dtor.rs (L62)) that would get duplicated. So this PR imports the 'fast' key type from `realstd` rather than using the local copy, to ensure its internal state (and that of the functions it calls) does not get duplicated. I also noticed that the `__OsLocalKeyInner` is unused under `cfg(target_thread_local)`, so I removed it for that configuration. There was a comment saying macOS picks between `__OsLocalKeyInner` and `__FastLocalKeyInner` at runtime, but I think that comment is outdated -- I found no trace of such a runtime switching mechanism, and the library still check-builds on apple targets with this PR. (I don't have a Mac so I cannot actually run it.)		2022-08-28 15:12:31 +00:00
