Release Notes

matklad/once_cell (once_cell)

v1.21.4

Compare Source

• Fix unsoundness in OnceCell::wait under --features=parking_lot, #​295.

  If thread A calls wait, while thread B calls get_or_try_init(f), and, furthermore, f panics,
  the wait incorrectly returns and thread A observes uninitialized memory.

  Kudos to @​meng-xu-cs for a nice find!

Stebalien/tempfile (tempfile)

v3.27.0

Compare Source

This release adds TempPath::try_from_path and deprecates TempPath::from_path.

Prior to this release, TempPath::from_path made no attempts to convert relative paths into absolute paths. The following code would have deleted the wrong file:

let tmp_path = TempPath::from_path("foo")
std::env::set_current_dir("/some/other/path").unwrap();
drop(tmp_path);

Now:

1. TempPath::from_path will attempt to convert relative paths into absolute paths. However, this isn't always possible as we need to call std::env::current_dir, which can fail. If we fail to convert the relative path to an absolute path, we simply keep the relative path.
2. The TempPath::try_from_path behaves exactly like TempPath::from_path, except that it returns an error if we fail to convert a relative path into an absolute path (or if the passed path is empty).

Neither function attempt to verify the existence of the file in question.

Thanks to @​meng-xu-cs for reporting this issue.

• Fix a number of bugs in time-related code by @​KodrAus in #​872
• Reword invalid char error message by @​KodrAus in #​873
• Impl cleanups by @​KodrAus in #​874

• Prepare for 1.23.0 release by @​KodrAus in #​876

New Contributors

• @​FrenchDilettante made their first contribution in #​865

Special thanks

@​meng-xu-cs raised a series of bugs against the timestamp logic in uuid using automated tooling. The issues themselves were reasonably and responsibly presented and the end result is a better uuid library for everyone. Thanks!

Deprecations

This release includes the following deprecations:

• Context: Renamed to ContextV1
• Timestamp::from_gregorian: Renamed to Timestamp::from_gregorian_time

Change to Version::Max

Version::Max's u8 representation has changed from 0xff to 0x0f to match the value returned by Uuid::get_version_num.

Change to Uuid::get_version for the max UUID

Uuid::get_version will only return Some(Version::Max) if the UUID is actually the max UUID (all bytes are 0xff). Previously it would return Some if only the version field was 0x0f. This change matches the behaviour of the nil UUID, which only returns Some(Version::Nil) if the UUID is the nil UUID (all bytes are 0x00).
