processes running on different threads. For example, before accessing\na non-threadsafe resource, a thread will lock the mutex. This is guaranteed\nto block the thread until no other thread holds a lock on the mutex and thus\nenforces exclusive access to the resource. Once the operation is complete, the\nthread releases the lock, allowing other threads to acquire a lock and access the\nresource.\u003c/p\u003e\n\u003cp dir=\"auto\"\u003eWhile Javascript is strictly single-threaded, the asynchronous nature of its\nexecution model allows for race conditions that require similar synchronization\nprimitives. Consider for example a library communicating with a web worker that\nneeds to exchange several subsequent messages with the worker in order to achieve\na task. As these messages are exchanged in an asynchronous manner, it is perfectly\npossible that the library is called again during this process. Depending on the\nway state is handled during the async process, this will lead to race conditions\nthat are hard to fix and even harder to track down.\u003c/p\u003e\n\u003cp dir=\"auto\"\u003eThis library solves the problem by applying the concept of mutexes to Javascript.\nLocking the mutex will return a promise that resolves once the mutex becomes\navailable. Once the async process is complete (usually taking multiple\nspins of the event loop), a callback supplied to the caller should be called in order\nto release the mutex, allowing the next scheduled worker to execute.\u003c/p\u003e\n\u003cdiv class=\"markdown-heading\" dir=\"auto\"\u003e\u003ch1 tabindex=\"-1\" class=\"heading-element\" dir=\"auto\"\u003eSemaphore\u003c/h1\u003e\u003ca id=\"user-content-semaphore\" class=\"anchor\" aria-label=\"Permalink: Semaphore\" href=\"#semaphore\"\u003e\u003csvg data-component=\"Octicon\" class=\"octicon octicon-link\" viewBox=\"0 0 16 16\" version=\"1.1\" width=\"16\" height=\"16\" aria-hidden=\"true\"\u003e\u003cpath d=\"m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z\"\u003e\u003c/path\u003e\u003c/svg\u003e\u003c/a\u003e\u003c/div\u003e\n\u003cp dir=\"auto\"\u003eImagine a situation where you need to control access to several instances of\na shared resource.

<p dir="auto">The term "mutex" usually refers to a data structure used to synchronize
concurrent processes running on different threads. For example, before accessing
a non-threadsafe resource, a thread will lock the mutex. This is guaranteed
to block the thread until no other thread holds a lock on the mutex and thus
enforces exclusive access to the resource. Once the operation is complete, the
thread releases the lock, allowing other threads to acquire a lock and access the
resource.</p>
<p dir="auto">While Javascript is strictly single-threaded, the asynchronous nature of its
execution model allows for race conditions that require similar synchronization
primitives. Consider for example a library communicating with a web worker that
needs to exchange several subsequent messages with the worker in order to achieve
a task. As these messages are exchanged in an asynchronous manner, it is perfectly
possible that the library is called again during this process. Depending on the
way state is handled during the async process, this will lead to race conditions
that are hard to fix and even harder to track down.</p>
<p dir="auto">This library solves the problem by applying the concept of mutexes to Javascript.
Locking the mutex will return a promise that resolves once the mutex becomes
available. Once the async process is complete (usually taking multiple
spins of the event loop), a callback supplied to the caller should be called in order
to release the mutex, allowing the next scheduled worker to execute.</p>

<p dir="auto">Imagine a situation where you need to control access to several instances of
a shared resource. For example, you might want to distribute images between several
worker processes that perform transformations, or you might want to create a web
crawler that performs a defined number of requests in parallel.</p>
<p dir="auto">A semaphore is a data structure that is initialized with an arbitrary integer value and that
can be locked multiple times.
As long as the semaphore value is positive, locking it will return the current value
and the locking process will continue execution immediately; the semaphore will
be decremented upon locking. Releasing the lock will increment the semaphore again.</p>
<p dir="auto">Once the semaphore has reached zero, the next process that attempts to acquire a lock
will be suspended until another process releases its lock and this increments the semaphore
again.</p>
<p dir="auto">This library provides a semaphore implementation for Javascript that is similar to the
mutex implementation described above.</p>

<p dir="auto">A shortcut exists for the case where you do not want to wait for a lock to
be available at all. The <code>tryAcquire</code> decorator can be applied to both mutexes
and semaphores and changes the behavior of <code>acquire</code> and <code>runExclusive</code> to
immediately throw <code>E_ALREADY_LOCKED</code> if the mutex is not available.</p>
