Golang PyGILState_GetThisThreadState Examples

Example #1

File: python.go Project: tsavola/go-python

func (t *Thread) loop() {
	runtime.LockOSThread()

	threadState := threadInit()
	if threadState == nil {
		gilState := C.PyGILState_Ensure()
		oldThreadState := C.PyGILState_GetThisThreadState()
		threadState = C.PyThreadState_New(oldThreadState.interp)
		C.PyGILState_Release(gilState)
	}

	for f := range t.queue {
		C.PyEval_RestoreThread(threadState)
		f()
		threadState = C.PyEval_SaveThread()
	}

	gilState := C.PyGILState_Ensure()
	C.PyThreadState_Clear(threadState)
	C.PyThreadState_Delete(threadState)
	C.PyGILState_Release(gilState)
}

Example #2

File: main.go Project: MogeiWang/embedding-python-in-golang

func init() {
	log.Debug("> Initilize Python.")

	runtime.LockOSThread()

	if C.Py_IsInitialized() == 0 {
		C.Py_Initialize()
	}
	if C.Py_IsInitialized() == 0 {
		panic(fmt.Errorf("python: could not initialize the python interpreter"))
	}

	// make sure the GIL is correctly initialized
	if C.PyEval_ThreadsInitialized() == 0 {
		C.PyEval_InitThreads()
	}
	if C.PyEval_ThreadsInitialized() == 0 {
		panic(fmt.Errorf("python: could not initialize the GIL"))
	}
	log.Debug("< Initilized Python.")
	_tstate := C.PyGILState_GetThisThreadState()
	C.PyEval_ReleaseThread(_tstate)
}
