The behavior makes sense because `Path::new("one_component").parent() ==
Some(Path::new(""))`, so if one naively wants to create the parent
directory for a file to be written, it simply works.
Closes rust-lang#105108 by documenting the current behavior.
Due to rust-lang#125954, we had to modify git invocations with certain flags in rust-lang#126255. However, because there are so many instances of `Command::new("git")` in bootstrap, it is difficult to apply these solutions to all of them. This PR creates a helper function that unifies the git usage in bootstrap. Meaning, whenever special flags or hacks are needed, we can apply them to this single function which makes things much simpler for the bootstrap team. Signed-off-by: onur-ozkan <[email protected]>
Clarify the language wrt `race condition` not meaning `memory unsafety`.

…elix Spell out other trait diagnostic I recently saw somebody confused about the diagnostic thinking it was suggesting to add an `as` cast. This change is longer but I think it's clearer

Update `Arc::try_unwrap()` docs Clarify the language wrt "race condition" not meaning "memory unsafety". The docs make an important point about a 'logical' race condition that can occur if the `Err`-case in `Arc::try_unwrap()` is not handled properly. The language as is uses the term "race condition", which the reader may associate with "memory unsafety". This PR tries to clarify the scenario and qualify "race condition without memory unsafety".
