Fixes #12216 Fixes a panic in `AbsolutePathBuf::parent()` when the process hits file descriptor exhaustion (`EMFILE` / "Too many open files"). ### Root cause `AbsolutePathBuf::parent()` was re-validating the parent path via `from_absolute_path(...).expect(...)`. `from_absolute_path()` calls `path_absolutize::absolutize()`, which can depend on `std::env::current_dir()`. Under `EMFILE`, that can fail, causing `parent()` to panic even though the parent of an absolute path is already known. ### Change - Stop re-absolutizing the result of `self.0.parent()` - Construct `AbsolutePathBuf` directly from the known parent path - Keep an invariant check with `debug_assert!(p.is_absolute())` ### Why this is safe `self` is already an `AbsolutePathBuf`, so `self.0` is absolute/normalized. The parent of an absolute path is expected to be absolute, so re-running fallible normalization here is unnecessary and can introduce unrelated panics. |
