go-trylock alternatives and similar packages
Based on the "Goroutines" category.
Alternatively, view go-trylock alternatives based on common mentions on social networks and blogs.
-
semaphore
Semaphore pattern implementation with timeout of lock/unlock operations based on channel and context. -
neilotoole/errgroup
Drop-in alternative to sync/errgroup, limited to a pool of N worker goroutines. -
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive. -
goccm
Go Concurrency Manager package limits the number of goroutines that allowed to run concurrently. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way.It supports specifying the overall timeout to avoid blocking and uses goroutine pool to improve efficiency. -
go-tools/multithreading
Manage a pool of goroutines using this lightweight library with a simple API. -
queue
Gives you a sync.WaitGroup like queue group accessibility. Helps you to throttle and limit goroutines, wait for the end of the all goroutines and much more. -
hands
A process controller used to control the execution and return strategies of multiple goroutines. -
concurrency-limiter
Concurrency limiter with support for timeouts , dynamic priority and context cancellation of goroutines. -
oversight
Oversight is a complete implementation of the Erlang supervision trees.

README
go-trylock
TryLock support on read-write lock for Golang
Interface
go-trylock implements sync.Locker.
Have same interfaces with sync.RWMutex
Documentation can be found at Godoc
Examples
import (
"context"
"time"
"errors"
"github.com/subchen/go-trylock/v2"
)
var mu = trylock.New()
func goroutineWrite() error {
if ok := mu.TryLock(context.Background()); !ok {
return errors.New("timeout, cannot TryLock !!!")
}
defer mu.Unlock()
// write something
}
func goroutineWriteTimeout() error {
if ok := mu.TryLockTimeout(1 * time.Second); !ok {
return errors.New("timeout, cannot TryLock !!!")
}
defer mu.Unlock()
// write something
}
func goroutineRead() {
if ok := mu.RTryLock(context.Background()); !ok {
return errors.New("timeout, cannot RTryLock !!!")
}
defer mu.RUnlock()
// read something
}
func goroutineReadTimeout() {
if ok := mu.RTryLockTimeout(1 * time.Second); !ok {
return errors.New("timeout, cannot RTryLock !!!")
}
defer mu.RUnlock()
// read something
}
