Gearman-Go

This module is a Gearman API for the Go Programming Language. The protocols were written in pure Go. It contains two sub-packages:

The client package is used for sending jobs to the Gearman job server, and getting responses from the server.

"github.com/mikespook/gearman-go/client"

The worker package will help developers in developing Gearman worker service easily.

Build Status GoDoc

Install

Install the client package:

$ go get github.com/mikespook/gearman-go/client

Install the worker package:

$ go get github.com/mikespook/gearman-go/worker

Both of them:

$ go get github.com/mikespook/gearman-go

Usage

Worker

// Limit number of concurrent jobs execution. Use worker.Unlimited (0) if you want no limitation.
w := worker.New(worker.OneByOne)
w.ErrHandler = func(e error) {
    log.Println(e)
}
w.AddServer("127.0.0.1:4730")
// Use worker.Unlimited (0) if you want no timeout
w.AddFunc("ToUpper", ToUpper, worker.Unlimited)
// This will give a timeout of 5 seconds
w.AddFunc("ToUpperTimeOut5", ToUpper, 5)
if err := w.Ready(); err != nil {
	log.Fatal(err)
	return
}
go w.Work()

Client

// ...
c, err := client.New("tcp4", "127.0.0.1:4730")
// ... error handling
defer c.Close()
c.ErrorHandler = func(e error) {
    log.Println(e)
}
echo := []byte("Hello\x00 world")
echomsg, err := c.Echo(echo)
// ... error handling
log.Println(string(echomsg))
jobHandler := func(job *client.Job) {
    log.Printf("%s", job.Data)
}
handle, err := c.Do("ToUpper", echo, client.JOB_NORMAL, jobHandler)
// ...
