This is a simple mutex library using memcached for the Go programming language (http://golang.org/).
Memcached client is golibmc (https://github.com/douban/libmc/blob/master/src/golibmc.go)
GoDoc is Here (https://godoc.org/github.com/mosasiru/mcmutex)
$ go get github.com/mosasiru/mcmutex
After this command mutex is ready to use. Its source will be in:
$GOPATH/src/github.com/mosasiru/mcmutex
import (
"github.com/douban/libmc/golibmc"
"github.com/mosasiru/mcmutex"
)
func main() {
mc := golibmc.SimpleNew([]string{"127.0.0.1:11211"})
mutex := mcmutex.NewMCMutex(mc)
defer mutex.Unlock("key")
if err := mutex.Lock("key"); err != nil {
println("lock failed")
return
}
...
}
retry count before acquisition lock (default: 0)
retry interval (default: 10ms)
lock will be expired after Expiration time (default: 30s)
This library features perl's KeyedMutex::Memcached (http://search.cpan.org/~zigorou/KeyedMutex-Memcached-0.01/lib/KeyedMutex/Memcached.pm)
