P#
phasync– The static API of phasync: start coroutines, wait for them, cancel them, and wait for streams and flags. CoroutinesPollerInterface– Waits for streams on behalf of the event loop. The event loopPool– A pool of interchangeable resources, of which only so many may exist at once. Resource managementProcess– Starts a child process whose standard streams are used from coroutines without blocking the others. ProcessesProcessInterface– A child process started with Process::run(), with its standard streams usable from coroutines. ProcessesProcessRunner– The implementation behind Process::run(): starts a child process and controls it. Processesphasync::await– Waits for a coroutine or a promise, and returns its result or throws the exception it ended with. Coroutinesphasync::awaitFlag– Suspends the current coroutine until $signal is raised with phasync::raiseFlag. Waiting and timeoutsphasync::cancel– Cancels a coroutine with a CancelledException. Cancellation and cleanupphasync::channel– Creates a channel and returns its two ends in $read and $write. Channels and messagingphasync::finally– Registers $fn to run when the current coroutine ends, or when the nested run() it is in returns. Cancellation and cleanupphasync::frame– Returns the frame of the running coroutine: that of the innermost run() it is in. Scopes and framesphasync::getFiber– Returns the running coroutine. The event loopphasync::getLoop– Returns the event loop, for code that waits with its low-level API (getSlot(), park() and unpark() of the returned object), or drives it in place (tick()). The event loopphasync::go– Starts $fn as a coroutine in the current frame and scope, and returns it, without waiting for it. Coroutinesphasync::idle– Suspends the current coroutine until the event loop has had nothing to run for at least $after seconds: the ready queue and the callback queue are both empty, and an immediate poll finds no I/O ready. Waiting and timeoutsphasync::isRunning– Returns true while a phasync::run is in progress, and false otherwise. The event loopphasync::onScopeChange– Registers $fn to be called when the current Scope changes as the event loop switches coroutines. Scopes and framesphasync::onSignal– Run $handler the moment $signo arrives, inside the signal handler: with pcntl_async_signals(true) in the middle of whatever is executing, even a coroutine that never yields; otherwise when the event loop dispatches signals. For what must happen at that moment, such as logging where a stuck process is; it must not suspend (no await, sleep or phasync I/O). Coroutines in phasync::signal are woken for the same signal as well. phasync takes the signal over until the outermost phasync::run() returns (a previous pcntl_signal() handler is called as well, and put back then), so register it for a run. Cancellation and cleanupphasync::publisher– Creates a publisher: what is written to $publisher is delivered to every subscription of $subscribers. Channels and messagingphasync::raiseFlag– Wakes every coroutine waiting for $signal in phasync::awaitFlag, and returns how many it woke. Waiting and timeoutsphasync::readable– Suspends the coroutine until the stream can be read without blocking, and returns the stream. Waiting and timeoutsphasync::run– Runs $fn and returns its result once it and every coroutine started inside it have ended. Coroutinesphasync::service– Starts $fn as a service: a coroutine of no frame, in the root scope, which outlives the code that started it, and returns it. The event loopphasync::shielded– Run $fn out of every cancellation's reach: phasync::cancel(), Frame::cancel(), and phasync::shutdown() don't cut its waits short. A cancellation that comes meanwhile applies at the coroutine's first wait after $fn returns. For infrastructure that must finish what it started, such as a server ending a protocol cleanly while the application's coroutines stop; application code rarely needs it. Cancellation and cleanupphasync::shutdown– Stop the program's coroutines: every coroutine but the caller, whatever frame it is in, gets $exception (a ShutdownException, which is a CancelledException) at its wait, as phasync::cancel() does, and has up to $window seconds to clean up: finally blocks, and phasync::finally() callbacks, which may wait. Returns how many are still running after that, for the caller to decide (for example to exit, dropping them). Cancellation and cleanupphasync::signal– Suspends the current coroutine until one of $signals (POSIX signal numbers such as SIGTERM) arrives, and returns the one that did. Any number of coroutines may wait for the same signal: each is woken. The waiter runs as an ordinary coroutine afterwards, so it may await, write and close connections; the signal's handler only records it, and the event loop wakes the waiters between coroutines, never inside one. A signal that came before the wait began doesn't end it. Cancellation and cleanupphasync::sleep– Pauses the current coroutine for $seconds, and lets the others run meanwhile. Waiting and timeoutsphasync::throw– Interrupts the wait of a suspended coroutine with $exception, once. Cancellation and cleanupphasync::writable– Suspends the coroutine until the stream can be written without blocking, and returns the stream. Waiting and timeoutsphasync::yield– Suspends the current coroutine until the loop has made its next round, after the coroutines that were ready have run. CoroutinesPollerInterface::poll– Waits up to $timeout seconds until a waited-for stream is ready, and unparks the waiters of those that are. The event loopPollerInterface::readable– Parks the current coroutine until poll() finds $stream readable. The event loopPollerInterface::writable– Parks the current coroutine until poll() finds $stream writable. The event loopPool::__construct– Creates an empty pool; instances are made when they are needed. Resource managementPool::borrow– Lends an instance to the caller until it calls release() or discard(), and waits while all are out. Resource managementPool::count– Returns the number of instances in existence: lent out, being made, and idle. Resource managementPool::discard– Gives a borrowed instance back as broken: the pool forgets it, passes it to $dispose, and makes a new one when needed. Resource managementPool::release– Gives a borrowed instance back, for the next borrower. Resource managementPool::use– Runs $fn with an instance of its own, and releases the instance afterwards, also when $fn throws. Resource managementProcess::run– Starts $command in the background and returns the object that controls it. ProcessesProcessInterface::getExitCode– Returns the exit code of the process, or false while it runs. ProcessesProcessInterface::getStream– Returns the stream of a standard descriptor, for stream_select(), phasync::readable() and the like. ProcessesProcessInterface::isRunning– Returns true if the process is running. ProcessesProcessInterface::isStopped– Returns true if the process is paused by a stop signal. ProcessesProcessInterface::read– Waits until the stream has something to read, and returns what is there. ProcessesProcessInterface::sendSignal– Sends a signal to the process, and returns false without sending it if the process is not running. ProcessesProcessInterface::stop– Ends the process: SIGTERM, then SIGKILL after one second, and waits up to five seconds in all. ProcessesProcessInterface::write– Waits until the stream can take data, and writes as much as it takes. ProcessesProcessRunner::__construct– Starts the process. ProcessesProcessRunner::getExitCode– Returns the exit code of the process, or false while it runs. ProcessesProcessRunner::getStream– Returns the stream of a standard descriptor. ProcessesProcessRunner::isRunning– Returns true if the process is running. ProcessesProcessRunner::isStopped– Returns true if the process is paused by a stop signal. ProcessesProcessRunner::read– Waits until the stream has something to read, and returns what is there; an empty string at the end of the stream. ProcessesProcessRunner::sendSignal– Sends a signal to the process, and returns false without sending it if the process is not running. ProcessesProcessRunner::sigcont– Sends SIGCONT, which resumes a process paused by sigstop(). ProcessesProcessRunner::sighup– Sends SIGHUP, which many daemons take as a request to reload their configuration. ProcessesProcessRunner::sigint– Sends SIGINT, the signal of Ctrl+C. ProcessesProcessRunner::sigkill– Sends SIGKILL, which a process cannot catch or ignore. ProcessesProcessRunner::sigstop– Sends SIGSTOP, which pauses the process until sigcont(). ProcessesProcessRunner::sigterm– Sends SIGTERM, which a process can catch to shut down. ProcessesProcessRunner::stop– Ends the process: SIGTERM, then SIGKILL after one second, and waits up to five seconds in all. ProcessesProcessRunner::write– Waits until the stream can take data, and writes as much as it takes; false if the process is not running. Processes

HTTP clientShutdownException– Thrown into the coroutines of a run by phasync::shutdown(): the program is stopping. It is a CancelledException, so it behaves like one: the coroutine meets it at its wait, its finally blocks run, and cleanup that must wait belongs in phasync::finally().

W#
WaitGroup– Waits until a counted amount of work has been done, like Go's sync.WaitGroup. Coordination and limitsWriteChannelInterface– The writing end of a channel: write() sends a value to the readers of the channel. Channels and messagingWaitGroup::add– Adds $delta to the counter of unfinished work. Coordination and limitsWaitGroup::await– Waits until the counter is zero. Coordination and limitsWaitGroup::done– Marks one piece of work as done. Coordination and limitsWaitGroup::isReady– Returns true when the counter is zero: nothing is left to wait for. Coordination and limitsWaitGroup::wait– Waits until the counter is zero. Coordination and limitsWriteChannelInterface::activate– Switches off the deadlock check of the channel. Channels and messagingWriteChannelInterface::close– Closes the channel, for both ends. Channels and messagingWriteChannelInterface::isClosed– Returns true if the channel has been closed. Channels and messagingWriteChannelInterface::isWritable– Returns true if the channel is open, so a write is accepted. Channels and messagingWriteChannelInterface::write– Sends a value, and waits while the channel cannot take it: for a reader on an unbuffered channel, for room on a full buffer. Channels and messaging
