faulthandler doesn't print the source code line (yet?). Here is the code: class ForkWait(unittest.TestCase): ... def f(self, id): while not self.stop: self.alive[id] = os.getpid() try: time.sleep(SHORTSLEEP) <~~~ here except IOError: pass ForkWait.f() is used by ForkWait.test_wait() which creates 4 threads. You may use all_threads=True option of faulthandler to get the backtrace of all threads. Because ForkWait.test_wait() uses fork, you may also need to dump the backtrace of two processes. Debug threads+multiple processes is something horrible :-) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11223> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
