Hi All, I'd like to here you opinion regarding hythread_suspend_all and hythread_resume_all functionality provided by TM. Actually I have to separate questions:
1) I found that hythread_suspend_all calls thread_safe_point_impl inside. There is no assertion regarding thread's state upon entering hythread_suspend_all. So it can be called in suspend disabled state and nobody (at least me) expects to have a safe point during hythread_suspend_all. The problem seems to be very similar with the one discussed in "[drlvm][threading] Possible race condition in implementation of conditional variables?" Your thoughts? 2) Assume I need to suspend all threads in particular group. Ok I pass that group to hythread_suspend_all. Later when all suspended threads should be resumed I pass the same group to hythread_resume_all. But threads were suspended group has changed. For example one new thread was added to it. So the questions are. Is it acceptable to have such "unsafe" functionality? Would it better to lock the group in hythread_suspend_all and unlock it in hythread_resume_all.
