0.5.0

Changes since 0.4.x

General

• PHP 8.1 or newer is now required.
• ext-pmmpthread 6.0 or newer is now required.

API changes

• SleeperHandler::addNotifier() now returns SleeperHandlerEntry. This is a thread-safe object used to create SleeperNotifier, and should be passed to the destination thread.
• SleeperHandler::addNotifier() no longer accepts SleeperNotifier. Notifiers are now created using SleeperHandlerEntry::createNotifier().
• SleeperHandler::removeNotifier() now accepts int $notifierId. This allows the main thread to retain only the notifier ID for later cleanup, saving memory.
• SleeperNotifier is no longer thread-safe, and must be instantiated within the destination thread using SleeperHandlerEntry::createNotifier(). Since the notification delivery does not require the notifier itself to be a thread-safe object, this allows for better performance by avoiding unnecessary locking and the inherent overhead of thread-safe objects.

0.4.0

Changes since 0.3.1

• pthreads ^5.0 is now required.

0.3.1

Changes since 0.3.0

• Accept pthreads ~3.2.0 || ^4.0.

0.1.6

Changes since 0.1.5

• Accept pthreads ~3.2.0 || ^4.0.

0.3.0

Changes since 0.2.0

• SleeperHandler now only accepts Closure for handlers, not callable. (You can use Closure::fromCallable() to convert a callable to a closure.)
• Improved performance of SleeperNotifier->wakeupSleeper() (less locking).
• SleeperHandler no longer keeps references to SleeperNotifier instances (not needed). NotifierEntry has therefore been removed.

0.2.0

Changes since 0.1.5

• The use of a thread-safe map for tracking notifications (instead of flags on each notifier) improves performance substantially:
  • Notification processing with large numbers of notifiers is much faster, since it's not required to synchronize with and bruteforce-search for notifiers causing a wakeup (less locks, and also less CPU time wasted).
  • Less locks are required during delivery of notifications (locks only required on the shared object and not on notifiers).
