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)
