2.1.0

  • Make use of hrtime() as monotonic time source if available (PHP 7.3)
  • Added Amp\Iterator\toArray()
  • Added Amp\Promise\timeoutWithDefault() (#245)
  • Added Amp\Promise\wrap() (#234)
  • Added Amp\Loop::now()
  • Fixed stale NativeDriver::$now values (#243)

2.0.7

  • Fixed recording of stack traces for double resolution in case AMP_DEBUG was not set as environment variable, defaulting to 0 now. (#217)
  • Loop::unreference() is ignored on invalid watchers now.
  • Invoke UV watchers in case no events or UV_DISCONNECT is indicated.
  • Ignore Loop::$driver not being set during shutdown, which might happen due to the unreliable shutdown order. (#212)

2.0.6

  • Resolution methods are now hidden in the Promise returned from Deferred::promise(). Their exposure was an implementation detail and never promised by the return type of Deferred::promise().
  • A named class is now used for promises, so you don't end up with an anonymous class in var_dump() and stack traces, which can be confusing.

2.0.5

  • Fixed possible notices in formatStacktrace(). This is an internal API, but the notices might appear on certain stack traces when running with AMP_DEBUG=true.
  • Fixed segfault with ev, see amphp/parallel-functions#3.
  • Dropped multiple definitions of Deferred and Emitter. These were introduced as performance hack, but relied on zend.assertions being disabled to change behavior, which is bad. The performance impact is believed to be rather low, because coroutines are used a lot more than Deferred in Amp v2.

2.0.4

  • Allow AMP_DEBUG to be defined via the environment.
  • Fix formatting of stack traces used for double resolution debugging.

2.0.3

  • Loop::set() replaces the current driver with a dummy driver for the time of gc_collect_cycles() now. This allows cyclic references to be cleaned up properly before the new driver is set. Without such a fix, cyclic references might have been cleaned up later, e.g. cancelling their watcher IDs on the new loop, thereby cancelling the wrong watchers.
  • Promise combinator functions (all(), any(), first(), some()) now preserve order of the given $promises` array argument.

2.0.2

  • Fixed warnings and timers in EventDriver.
  • Does no longer hide warnings from stream_select.

2.0.1

  • Fixed an issue where the loop blocks even though all watchers are unreferenced.

2.0.0

  • Amp\reactor() has been replaced with Amp\Loop::set() and Amp\Loop::get().
  • Amp\driver() has been replaced with Amp\Loop\Factory::create().
  • Amp\tick() no longer exists and doesn't have a replacement. Ticks are an internal detail.
  • Functions for creating and managing watchers are now static methods of Amp\Loop instead of functions in the Amp namespace.
    • once() is now delay() and immediately() is defer().
    • Parameter order for delay() and repeat() has been changed.
    • reference() and unreference() have been added.
  • Amp\Pause has been renamed to Amp\Delayed and accepts an optional resolution value now. Additionally reference() and unreference() methods have been added.
  • Promise accepting functions have been moved to the Amp\Promise namespace.
  • Amp\Promise\some() accepts an additional $required parameter.
  • Amp\call(), Amp\asyncCall(), Amp\coroutine() and Amp\asyncCoroutine() have been added.
  • Amp\resolve() has been removed, use Amp\call() instead.
  • Promise::when() has been renamed to Promise::onResolve()
  • Promise::watch() has been removed, use Amp\Iterator, amphp/byte-stream or a custom implementation that implements Amp\Promise instead and provides dedicated APIs to access the previously data shared via the watch() mechanism.
  • Amp\Iterator, Amp\Emitter and Amp\Producer have been added with several functions in the Amp\Iterator namespace.
  • Various other changes.

1.2.2

  • Fix notice in NativeReactor when removing a handle while an event is waiting for it. (Regression fix from 1.1.1)

1.2.1

  • Fix uv_run() potentially exiting earlier than intended, leading to an infinite loop in UvReactor::run().

1.2.0

  • resolve() now also accepts callables returning generators.

1.1.1

  • Fix memory leak in NativeReactor, retaining an empty array for each stream.
  • Remove circular references in UvReactor to avoid garbage collector calls.

1.1.0

  • Add getExceptions() method to CombinatorException to get an array of all the exceptions (affecting some() and first()).
  • Fix NativeReactor not ending up in stopped state if primary callback didn't install any events.

1.0.8

  • Fix NativeReactor running a busy loop if no timers are active. Properly block now in NativeReactor inside stream_select().

1.0.7

  • Several combinator functions could result in a promise already resolved exception in case some values of the array weren't promises.

1.0.6

  • Fix issue in NativeReactor causing stop() to be delayed by one second.

1.0.5

  • Convert general RuntimeException to more specific Amp\CombinatorException.

1.0.4

  • Repeat watchers in LibeventReactor internally were handled in microsecond intervals instead of milliseconds.

1.0.3

  • Fix issue in NativeReactor capable of causing keep alive counter corruption when a watcher was cancelled inside its own callback.
  • Fix issue in UvReactor with libuv >= 1.1.0 causing busy loop with immediates present, but no watchers being triggered.

1.0.2

  • Fix PHP 7 issue in which top-level Throwables weren't caught in certain coroutine contexts.
  • Remove error suppression operator on optionally null option assignment to avoid spurious E_NOTICE output when custom error handlers are used.

1.0.1

  • Fix bug preventing UvReactor::tick() from returning when no events are ready for a single active IO watcher.

1.0.0

  • Initial stable API release
