[jira] [Created] (THRIFT-4240) Go TSimpleServer does not close
properly
Zach Wasserman created THRIFT-4240:
--------------------------------------
Summary: Go TSimpleServer does not close properly
Key: THRIFT-4240
URL: https://issues.apache.org/jira/browse/THRIFT-4240
Project: Thrift
Issue Type: Bug
Components: Go - Library
Affects Versions: 0.10.0
Reporter: Zach Wasserman
Improper use of {{sync.Once}} results in only the first call to {{Close()}} in a given process actually executing.
The {{sync.Once}} object should be a struct member, and not package global.
Test:
{code}
type mockProcessor struct {
ProcessFunc func(in, out TProtocol) (bool, TException)
}
func (m *mockProcessor) Process(in, out TProtocol) (bool, TException) {
return m.ProcessFunc(in, out)
}
type mockServerTransport struct {
ListenFunc func() error
AcceptFunc func() (TTransport, error)
CloseFunc func() error
InterruptFunc func() error
}
func (m *mockServerTransport) Listen() error {
return m.ListenFunc()
}
func (m *mockServerTransport) Accept() (TTransport, error) {
return m.AcceptFunc()
}
func (m *mockServerTransport) Close() error {
return m.CloseFunc()
}
func (m *mockServerTransport) Interrupt() error {
return m.InterruptFunc()
}
func TestMultipleStop(t *testing.T) {
proc := &mockProcessor{
ProcessFunc: func(in, out TProtocol) (bool, TException) {
return false, nil
},
}
var interruptCalled bool
c := make(chan struct{})
trans := &mockServerTransport{
ListenFunc: func() error {
return nil
},
AcceptFunc: func() (TTransport, error) {
<-c
return nil, nil
},
CloseFunc: func() error {
c <- struct{}{}
return nil
},
InterruptFunc: func() error {
interruptCalled = true
return nil
},
}
serv := NewTSimpleServer2(proc, trans)
go serv.Serve()
serv.Stop()
if !interruptCalled {
t.Error("first server transport should have been interrupted")
}
serv = NewTSimpleServer2(proc, trans)
interruptCalled = false
go serv.Serve()
serv.Stop()
if !interruptCalled {
t.Error("second server transport should have been interrupted")
}
}
{code}
Output:
{code}
go test -race -run TestMultipleStop
--- FAIL: TestMultipleStop (0.00s)
simple_server_test.go:96: second server transport should have been interrupted
FAIL
exit status 1
