From cef99a8c77da2b7f6ea26aa20443a07be48ae3fc Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Wed, 27 Jun 2001 19:19:46 +0000 Subject: Revise the interface to the profiling and tracing support for the Python interpreter. This change adds two new C-level APIs: PyEval_SetProfile() and PyEval_SetTrace(). These can be used to install profile and trace functions implemented in C, which can operate at much higher speeds than Python-based functions. The overhead for calling a C-based profile function is a very small fraction of a percent of the overhead involved in calling a Python-based function. The machinery required to call a Python-based profile or trace function been moved to sysmodule.c, where sys.setprofile() and sys.setprofile() simply become users of the new interface. As a side effect, SF bug #436058 is fixed; there is no longer a _PyTrace_Init() function to declare. --- Python/pystate.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) (limited to 'Python/pystate.c') diff --git a/Python/pystate.c b/Python/pystate.c index 8e5896a44f..192c4c14f6 100644 --- a/Python/pystate.c +++ b/Python/pystate.c @@ -120,8 +120,10 @@ PyThreadState_New(PyInterpreterState *interp) tstate->exc_value = NULL; tstate->exc_traceback = NULL; - tstate->sys_profilefunc = NULL; - tstate->sys_tracefunc = NULL; + tstate->c_profilefunc = NULL; + tstate->c_tracefunc = NULL; + tstate->c_profileobj = NULL; + tstate->c_traceobj = NULL; HEAD_LOCK(); tstate->next = interp->tstate_head; @@ -152,8 +154,10 @@ PyThreadState_Clear(PyThreadState *tstate) ZAP(tstate->exc_value); ZAP(tstate->exc_traceback); - ZAP(tstate->sys_profilefunc); - ZAP(tstate->sys_tracefunc); + tstate->c_profilefunc = NULL; + tstate->c_tracefunc = NULL; + ZAP(tstate->c_profileobj); + ZAP(tstate->c_traceobj); } -- cgit v1.2.1
