tokio::sync. In addition, it adds new unstable APIs to tokio::task (Ids
for uniquely identifying a task, and AbortHandle for remotely cancelling a
task), as well as a number of bugfixes.

  where Instant::now is not monotonic (#​4461)
• io: fix DuplexStream not participating in cooperative yielding
  (#​4478)
• rt: fix potential double panic when dropping a JoinHandle (#​4430)

• update parking_lot dependency to v0.12.0 (#​4459)
• update mio dependency to v0.8 (#​4449)

v1.16.1

Compare Source

1.16.1 (January 28, 2022)

This release fixes a bug in #​4428 with the change #​4437.

v1.16.0

Compare Source

Fixes a soundness bug in io::Take (#​4428). The unsoundness is exposed when
leaking memory in the given AsyncRead implementation and then overwriting the
supplied buffer:

impl AsyncRead for Buggy {
    fn poll_read(
        self: Pin<&mut Self>,
        cx: &mut Context<'_>,
        buf: &mut ReadBuf<'_>
    ) -> Poll<Result<()>> {
      let new_buf = vec![0; 5].leak();
      *buf = ReadBuf::new(new_buf);
      buf.put_slice(b"hello");
      Poll::Ready(Ok(()))
    }
}

Also, this release includes improvements to the multi-threaded scheduler that
can increase throughput by up to 20% in some cases (#​4383).

Fixed

• io: soundness don't expose uninitialized memory when using io::Take in edge case (#​4428)
• fs: ensure File::write results in a write syscall when the runtime shuts down (#​4316)
• process: drop pipe after child exits in wait_with_output (#​4315)
• rt: improve error message when spawning a thread fails (#​4398)
• rt: reduce false-positive thread wakups in the multi-threaded scheduler (#​4383)
• sync: don't inherit Send from parking_lot::*Guard (#​4359)

Added

• net: TcpSocket::linger() and set_linger() (#​4324)
• net: impl UnwindSafe for socket types (#​4384)
• rt: impl UnwindSafe for JoinHandle (#​4418)
• sync: watch::Receiver::has_changed() (#​4342)
• sync: oneshot::Receiver::blocking_recv() (#​4334)
• sync: RwLock blocking operations (#​4425)

Unstable

The following changes only apply when building with --cfg tokio_unstable

• rt: breaking change overhaul runtime metrics API (#​4373)

v1.15.0

Compare Source

Fixed

• io: add cooperative yielding support to io::empty() (#​4300)
• time: make timeout robust against budget-depleting tasks (#​4314)

Changed

• update minimum supported Rust version to 1.46.

Added

• time: add Interval::reset() (#​4248)
• io: add explicit lifetimes to AsyncFdReadyGuard (#​4267)
• process: add Command::as_std() (#​4295)

Added (unstable)

• tracing: instrument tokio::sync types (#​4302)
