Release Notes

Amanieu/parking_lot (lock_api)

v0.5.0

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)
