[Python-Dev] Set PyEval_SetTrace to method from class
Hello. I need to set a PyEval_SetTrace with a new class instance. All examples use simple function. PyEval_SetTrace(trace_trampoline, obj); Following my problem: I start three threads, but I need to check trace C just one thread. If I run a while on C trace on thread, it stops all threads. So, I've been thinking to run Trace with a new instance class C. Any suggestions? Att.

[Python-Dev] Clean memory on C trace
Hi.
I need to clean memory on function on PyEval_SetTrace.
When the python code run a while test, the memory consumption goes up a lot
(99% of the system).
exemple:
while 1 == 1:
pass
My trace function is simple.
static map session_debug_user;
char *user_console;
int trace_trampoline(
PyObject *obj, PyFrameObject *frame, int event, PyObject *arg)
{
try
{
//check if user has debug session
if (session_debug_user.count(user_console) == 0)
{
return 0;
}
return 0;
}
PyObject *sys_settrace(PyObject *mod, PyObject *obj)
{
user_console = get_variable_char(obj, 0);
PyEval_SetTrace(trace_trampoline, obj);
return Py_None;
}

[Python-Dev] Re: Jump on C by PyEval_SetTrace Python 3.7.7 - SOLUTION
Hello Victor Stinner.
Thanks.
Your tip helped me a lot.
I understood that I need to get position on bycode of the line.
So I create the funcion to get position inside of the bycode.
Now I can to jump the correct position on trace.
frame->f_lasti = checkBycodePosition(frame->f_code, 11);
int checkBycodePosition(PyCodeObject *co, int fline)
{
Py_ssize_t size = PyBytes_Size(co->co_lnotab) / 2;
unsigned char *p = (unsigned char *)PyBytes_AsString(co->co_lnotab);
int line = co->co_firstlineno;
int addr = 0;
while (--size >= 0)
{
addr += *p++;
line += (signed char)*p;
if (line == fline)
break;
p++;
}
return addr;
}

Hi.
When I changed frame->f_lasti change de code to back, it's work but the line in
front code occurs dump, the runtime over.
Example:
I jump to 8 line and after I jump to line 10, it occurs dump.
On python trace pdb the jump works good by the frame-f_lineno.

Hi,
It seems like you should be to modify frame->f_lasti in a trace function
FYI in a frame object, the line number is computed using
frame->f_lasti and f->f_code->co_lnotab: PyFrame_GetLineNumber().
See: https://github.com/python/cpython/blob/master/Objects/lnotab_notes.txt
Good luck ;-)

[Python-Dev] Jump on C by PyEval_SetTrace Python 3.7.7
Hi everyone.
I'm trying to make a simple jump on C funcion trace by frame->f_lineno.
Example is simple, but not working.
if (frame->f_lineno == 12){
frame->f_lineno = 8;
}
attached files C and python to run test.
the line 12 I need to jump to line 8.
