许杰友 Jieyou Xu (Joe) f860f5bf90 Rollup merge of #131505 - madsmtm:darwin_user_temp_dir, r=dtolnay ... use `confstr(_CS_DARWIN_USER_TEMP_DIR, ...)` as a `TMPDIR` fallback on Darwin Rebased version of https://github.com/rust-lang/rust/pull/100824, FCP has completed there. Motivation from https://github.com/rust-lang/rust/pull/100824#issuecomment-1262264127: > This is a behavioral change in an edge case on Darwin platforms (macOS, iOS, ...). > > Specifically, this changes it so that iff `TMPDIR` is unset in the environment, then we use `confstr(_CS_DARWIN_USER_TEMP_DIR, ...)` to query the user temporary directory (previously we just returned `"/tmp"`). If this fails (probably possible in a sandboxed program), only then do we fallback to `"/tmp"` (as before). > > The motivations here are two-fold: > > 1. This is better for security, and is in line with the [platform security recommendations](https://developer.apple.com/library/archive/documentation/Security/Conceptual/SecureCodingGuide/Articles/RaceConditions.html#//apple_ref/doc/uid/TP40002585-SW10), as it is unavailable to other users (although it is the same value as seen by all other processes run by the same user). > 2. This is a more consistent fallback for when `getenv("TMPDIR")` is unavailable, as `$TMPDIR` is usually initialized to the `DARWIN_USER_TEMP_DIR`. > > It seems quite unlikely that anybody will break because of this, and I think it falls under the carve-out we have for platform specific behavior: https://doc.rust-lang.org/nightly/std/io/index.html#platform-specific-behavior.
