Armin Rigo <ar...@users.sourceforge.net> added the comment: Antoine: we could take two lines from the current implementation of these hook from stm/transactionmodule.c, and move them to the interpreter core. CPython would end up with containing the core logic for transactions. A possible API would look like that:
/* stops all threads different from 'tstate' at their next bytecode, at which point the given callback is invoked */ _PyEval_SetThreadStopper(PyThreadState *tstate, void (*callback)(void)); Such a function can also be tested in CPython, e.g. with ctypes. Still maybe a different name would be better, like _PyEval_InternalThreadStopper(). Or, if that's still a callback too much: /* stops all threads different from 'tstate' at their next bytecode, at which point they wait for the 'lock' to be available */ _PyEval_SetThreadStopper(PyThreadState *tstate, PyThread_lock_type lock); ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12850> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
