Eliza Weisman 6c03e03898 test: remove churn() task from lifo_stealable (#8070) 
Currently, the `rt_threaded::lifo_stealable` test I added in #7431
spawns an additional task which sleeps on a 4ms timer in a loop. This
ensures that no worker remains permanently parked. This was added
because it was necessary to stop the LIFO slot deadlock from occurring
prior to changes in the logic for determining whether to notify another
worker, which is what @Darksonn  was referring to in [this comment][1].
Removing the `churn()` test makes the test actually validate that
another worker is notified to steal the LIFO task, and that the changes
from #7431 will *always* prevent a LIFO slot deadlock, regardless of the
behavior of other tasks on the runtime. See also [this comment][2] for
further discussion.

BarryandMattia Pitossi 1afb391350 net: document pipe try_read*/try_write* readiness behavior (#8032) 
Add a Notes section to all five try_* methods on pipe::Sender and
pipe::Receiver explaining that the runtime's I/O driver only delivers
readiness events after control is yielded back to it, so calling
try_read/try_write before any .await returns WouldBlock even when the
operation could otherwise succeed.

This is the same readiness model used by every other Tokio I/O type;
the pipe docs simply did not previously call it out. Refs #7625.

Eliza Weisman 905c146aed chore: prepare to release v1.52.1 (#8059) 
# 1.52.1 (April 16th, 2026)

## Fixed

- runtime: revert [#7757] to fix [a regression][#8056] that causes
  `spawn_blocking` to hang ([#8057])

tokio-1.52.1 		2026-04-16 21:28:05 +00:00
Eliza Weisman 56aaa43e91 rt: revert #7757 to fix regression in spawn_blocking (#8057) 
This reverts commit 1604bc3351.

Unfortunately, this commit introduced a regression that causes programs
using `spawn_blocking` to hang (see #8056). To fix the regression, we
need to undo this change and publish a v1.52.1 release as soon as
possible.

In the future, we may wish to bring back a sharded queue for
`spawn_blocking` tasks, either based on the implementation added in
#7757 or a new one. However, since this is a substantial change to the
runtime internals, I think such a change should probably be done as an
unstable, opt-in `tokio::runtime::Builder` setting initially, so that we
don't regress existing users. I had hoped we could do this now, but
unfortunately, the sharded queue implementation from #7757 is kind of
tightly coupled with the rest of the `spawn_blocking` machinery and
cannot be easily swapped out --- and the hang still occurs with
`NUM_SHARDS` set to 1, so there isn't an easy way to turn it on and off.
Therefore, in the interest of getting a fix out ASAP, this is just a
simple revert.

Fixes #8056

Eliza Weisman 5f7be0ac42 chore: perpare 1.52.0 (#8045) 
# 1.52.0 (April 14th, 2026)

## Added

- io: `AioSource::register_borrowed` for I/O safety support ([#7992])
- net: add `try_io` function to `unix::pipe` sender and receiver types
  ([#8030])

## Added (unstable)

- runtime: `Builder::enable_eager_driver_handoff` setting enable eager
  hand off of the I/O and time drivers before polling tasks ([#8010])
- taskdump: add `trace_with()` for customized task dumps ([#8025])
- taskdump: allow `impl FnMut()` in `trace_with` instead of just `fn()`
  ([#8040])
- fs: support `io_uring` in `AsyncRead` for `File` ([#7907])

## Changed

- runtime: improve `spawn_blocking` scalability with sharded queue
  ([#7757])
- runtime: use `compare_exchange_weak()` in worker queue ([#8028])

## Fixed

- runtime: overflow second half of tasks when local queue is filled
  instead of first half ([#8029])

## Documented

- docs: hide #[tokio::main] attribute in the docs of `sync::watch`
  ([#8035])
