func GoID ¶

func GoID() int

Types ¶

type Pool ¶ added in v0.2.0

type Pool struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Pool is a struct to represent goroutine pool.

func NewGoroutinePool ¶ added in v0.2.0

func NewGoroutinePool(idleTimeout time.Duration) *Pool

New returns a new *Pool object. DEPRECATED: https://github.com/pingcap/tidb/pull/7564 After Go1.11, goroutine pool is harmful.

The test result is as follows: go test -test.bench Benchmark goos: darwin goarch: amd64 pkg: github.com/AlexStocks/goext/runtime BenchmarkGoPool-4 3000000 619 ns/op BenchmarkGo-4 5000000 319 ns/op BenchmarkMorestackPool-4 3000000 534 ns/op BenchmarkMoreStack-4 2000000 667 ns/op

func (*Pool) Close ¶ added in v0.2.0

func (p *Pool) Close()

func (*Pool) Go ¶ added in v0.2.0

func (p *Pool) Go(f func()) error

Go works like go func(), but goroutines are pooled for reusing. This strategy can avoid runtime.morestack, because pooled goroutine is already enlarged.

func (*Pool) IsClosed ¶ added in v0.2.0

func (p *Pool) IsClosed() bool

check whether the pool has been closed.
