From d083839fb4f44ff66792d80f7a71863600ca4638 Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Sat, 16 Jun 2001 21:02:31 +0000 Subject: Instead of initializing & interning the strings passed to the profile and trace functions lazily, which incurs extra argument pushing and checks in the C overhead for profiling/tracing, create the strings semi-lazily when the Python code first registers a profile or trace function. This simplifies the trampoline into the profile/trace functions. --- Python/sysmodule.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'Python/sysmodule.c') diff --git a/Python/sysmodule.c b/Python/sysmodule.c index 52fbbc89d3..62e08414d8 100644 --- a/Python/sysmodule.c +++ b/Python/sysmodule.c @@ -196,10 +196,14 @@ static char setdefaultencoding_doc[] = \n\ Set the current default string encoding used by the Unicode implementation."; +extern int _PyTrace_Init(void); + static PyObject * sys_settrace(PyObject *self, PyObject *args) { PyThreadState *tstate = PyThreadState_Get(); + if (_PyTrace_Init() == -1) + return NULL; if (args == Py_None) args = NULL; else @@ -220,6 +224,8 @@ static PyObject * sys_setprofile(PyObject *self, PyObject *args) { PyThreadState *tstate = PyThreadState_Get(); + if (_PyTrace_Init() == -1) + return NULL; if (args == Py_None) args = NULL; else -- cgit v1.2.1
