Release Notes

Amanieu/parking_lot (parking_lot)

`v0.13.0`

Compare Source

Signficantly improved Mutex and RwLock performance under contention by
deferring waking up parked threads until after the lock is released. (#545)
Added per-acquisition state to lock_api raw locks. RawMutex::Guard
replaces GuardMarker; rwlocks have separate SharedGuard, ExclusiveGuard,
and UpgradableGuard types. Unlock operations consume this state, while
upgrade and downgrade operations return replacement state. Bump and raw
condition-variable waits borrow and update the state. Consuming operations
must release their acquisition on unwind; borrowing operations must restore
ownership and valid state, or abort if restoration fails. (#544)
Raised the MSRV to Rust 1.95 and upgraded all crates to edition 2024. (#533)
Removed the hardware-lock-elision feature. (#533)
Removed automatic eventual fairness. Fair unlocking remains available through
the explicit fair-unlock APIs. This removes UnparkResult::be_fair. (#533)
Removed the no-op lock_api/nightly feature. (#533)
Removed the legacy lock_api const_new methods and the redundant
parking_lot const_* constructor functions; the corresponding new
methods can be called in constant contexts. (#533)
Replaced the recursive read methods on RwLock with a dedicated reader-biased
RecursiveRwLock type. The RawRwLockRecursive and RawRwLockRecursiveTimed
extension traits have been removed from lock_api. (#533)
Added Once::new_completed for constructing a Once in the completed state. (#520)
Added Once::{is_completed, wait, wait_force} and the corresponding
OnceState query methods. (#533)
Made additional lock, timeout, parking, and spin-wait accessors usable in
constant contexts. (#533)
Added into_inner_with_raw to lock_api's Mutex, RwLock, and ReentrantMutex. (#524)
Added RawCondvar, RawCondvarTimed, and the generic Condvar wrapper to
lock_api, and implemented parking_lot::Condvar using them. Custom raw
condition variables may allow spurious wakeups; their notification methods
must then return false or 0. parking_lot::Condvar still guarantees no
spurious wakeups and exact notification counts. (#523) (#533)
Corrected the Send and Sync bounds of lock guards in lock_api. (#533)
Made RawMutex::is_locked and RawRwLock::{is_locked, is_locked_exclusive} required methods. (#533)
Renamed MappedRwLockReadGuard::try_map_or_else to try_map_or_err. (#533)
Clarified the safety requirements of raw lock implementations, including
acquire/release synchronization, moving or dropping a locked raw lock,
preserving the original lock mode on a failed upgrade, and stable thread IDs.
Acquisitions may unwind without leaving a new acquisition held; consuming
guard operations release their acquisition on unwind, while bump and wait
operations must restore ownership or abort. (#533) (#544)
Clarified the aliasing requirements of unsafe raw-access, force-unlock, and
guard-construction APIs in lock_api. (#533)
Guard unlocked and unlocked_fair operations now abort if re-locking panics.
Default raw-lock bump implementations also abort if re-locking panics. (#533)
Guard with_upgraded operations abort if raw upgrading or downgrading panics,
preserving continuous lock ownership. (#544)
Parking-lot operations in parking_lot_core are now guaranteed to never
unwind. (#533)
Documented that parking-lot-based synchronization primitives must not be used
internally by global allocators. (#533)
Fixed unlock_upgradable_fair not forcing a fair handoff. (#533)
Fixed conditional Condvar waits reporting a timeout without rechecking the predicate. (#533)
Fixed the generic thread parker continuously busy-spinning while parked. (#533)
Fixed parking on WASI by using the pthread backend when the nightly atomic
intrinsics are unavailable, including on stable threaded WASI targets. (#538)
Fixed timed waits on ESP-IDF using the wrong clock. (#533)
Made timed waits on Apple platforms independent of wall-clock changes. (#533)
Fixed the futex timeout ABI on 32-bit Linux targets, including time64-only
architectures, with fallback to time32 when the kernel lacks time64 support. (#533)
Corrected RwLock deadlock tracking to avoid false positives and missed
cycles, and prevented dependency feature unification from enabling tracking
when only parking_lot_core/deadlock_detection is enabled. (#533)
Added Once deadlock tracking and made overlapping wait cycles report as a
single component. (#533)
Fixed compilation on L4Re. (#549)

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

any of the package files in this branch needs updating, or
the branch becomes conflicted, or
you click the rebase/retry checkbox if found above, or
you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: Cargo.lock

    Updating crates.io index
error: failed to select a version for `parking_lot`.
    ... required by package `conduwuit_core v26.9.1 (/tmp/renovate/repos/forgejo/continuwuation/continuwuity/src/core)`

versions that meet the requirements `^0.13.0` are: 0.13.0

package `conduwuit_core` depends on `parking_lot` with feature `hardware-lock-elision` but `parking_lot` does not have that feature.
