From 50b48572d9a90c5bb36e2bef6179548ea927a35a Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 1 Nov 2018 01:51:40 +0100 Subject: bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266) If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined. --- Python/thread_pthread.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'Python/thread_pthread.h') diff --git a/Python/thread_pthread.h b/Python/thread_pthread.h index 697140558f..6da8b3a447 100644 --- a/Python/thread_pthread.h +++ b/Python/thread_pthread.h @@ -174,7 +174,7 @@ PyThread_start_new_thread(void (*func)(void *), void *arg) return PYTHREAD_INVALID_THREAD_ID; #endif #if defined(THREAD_STACK_SIZE) - PyThreadState *tstate = PyThreadState_GET(); + PyThreadState *tstate = _PyThreadState_GET(); size_t stacksize = tstate ? tstate->interp->pythread_stacksize : 0; tss = (stacksize != 0) ? stacksize : THREAD_STACK_SIZE; if (tss != 0) { @@ -591,7 +591,7 @@ _pythread_pthread_set_stacksize(size_t size) /* set to default */ if (size == 0) { - PyThreadState_GET()->interp->pythread_stacksize = 0; + _PyInterpreterState_GET_UNSAFE()->pythread_stacksize = 0; return 0; } @@ -608,7 +608,7 @@ _pythread_pthread_set_stacksize(size_t size) rc = pthread_attr_setstacksize(&attrs, size); pthread_attr_destroy(&attrs); if (rc == 0) { - PyThreadState_GET()->interp->pythread_stacksize = size; + _PyInterpreterState_GET_UNSAFE()->pythread_stacksize = size; return 0; } } -- cgit v1.2.1
