pool
:speedboat: a limited consumer goroutine or unlimited goroutine pool for easier goroutine handling and cancellation -
Goflow
Simply way to control goroutines execution order based on dependencies -
artifex
Simple in-memory job queue for Golang using worker-based dispatching -
go-workers
๐ท Library for safely running groups of workers concurrently or consecutively that require input and output through channels -
async
A safe way to execute functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery. -
go-actor
A tiny library for writing concurrent programs in Go using actor model -
gollback
Go asynchronous simple function utilities, for managing execution of closures and callbacks -
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive. -
gpool
gpool - a generic context-aware resizable goroutines pool to bound concurrency based on semaphore. -
go-do-work
Dynamically resizable pools of goroutines which can queue an infinite number of jobs. -
goccm
Limits the number of goroutines that are allowed to run concurrently -
routine
go routine control, abstraction of the Main and some useful Executors.ๅฆๆไฝ ไธไผ็ฎก็Goroutine็่ฏ๏ผ็จๅฎ -
gowl
Gowl is a process management and process monitoring tool at once. An infinite worker pool gives you the ability to control the pool and processes and monitor their status. -
kyoo
Unlimited job queue for go, using a pool of concurrent workers processing the job queue entries -
go-waitgroup
A sync.WaitGroup with error handling and concurrency control -
channelify
Make functions return a channel for parallel processing via go routines. -
execpool
A pool that spins up a given number of processes in advance and attaches stdin and stdout when needed. Very similar to FastCGI but works for any command. -
go-tools/multithreading
A collection of tools for Golang -
concurrency-limiter
Concurrency limiter with support for timeouts , dynamic priority and context cancellation of goroutines. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way. It supports specifying the overall timeout to avoid blocking. -
hands
Hands is a process controller used to control the execution and return strategies of multiple goroutines. -
queue
package queue gives you a queue group accessibility. Helps you to limit goroutines, wait for the end of the all goroutines and much more. -
async-job
AsyncJob is an asynchronous queue job manager with light code, clear and speed. I hope so ! ๐ฌ

README
๐ฆ semaphore
Semaphore pattern implementation with timeout of lock/unlock operations.
๐ก Idea
The semaphore provides API to control access to a shared resource by multiple goroutines or limit throughput.
releaser, err := semaphore.Acquire(breaker.BreakByTimeout(time.Second))
if err != nil {
// timeout exceeded
}
defer releaser.Release()
Full description of the idea is available here.

๐คผโโ๏ธ How to
Quick start
limiter := semaphore.New(1000)
http.HandleFunc("/", func(rw http.ResponseWriter, req *http.Request) {
if _, err := limiter.Acquire(
breaker.BreakByContext(
context.WithTimeout(req.Context(), time.Second),
),
); err != nil {
http.Error(rw, http.StatusText(http.StatusTooManyRequests), http.StatusTooManyRequests)
return
}
defer limiter.Release()
// handle request
})
log.Fatal(http.ListenAndServe(":80", http.DefaultServeMux))
๐งฉ Integration
The library uses SemVer for versioning, and it is not BC-safe through major releases. You can use go modules or dep to manage its version.
The master is a feature frozen branch for versions 4.3.x and no longer maintained.
$ dep ensure -add github.com/kamilsk/[email protected]
The v4 branch is a continuation of the master branch for versions v4.4.x to better integration with go modules.
$ go get -u github.com/kamilsk/semaphore/[email protected]
The v5 branch is an actual development branch.
$ go get -u github.com/kamilsk/semaphore # inside GOPATH and for old Go versions
$ go get -u github.com/kamilsk/semaphore/v5 # inside Go module, works well since Go 1.11
$ dep ensure -add github.com/kamilsk/[email protected]
Version v5 focused on integration with the ๐ง breaker package.
