Willy Tarreau 7e70bfc8cb MINOR: threads: add a thread_harmless_end() version that doesn't wait ... thread_harmless_end() needs to wait for rdv_requests to disappear so that we're certain to respect a harmless promise that possibly allowed another thread to proceed under isolation. But this doesn't work in a signal handler because a thread could be interrupted by the debug handler while already waiting for isolation and with rdv_request>0. As such this function could cause a deadlock in such a signal handler. Let's implement a specific variant for this, thread_harmless_end_sig(), that just resets the thread's bit and doesn't wait. It must of course not be used past a check point that would allow the isolation requester to return and see the thread as temporarily harmless then turning back on its promise. This will be needed to fix a race in the debug handler.		2023-01-19 19:22:17 +01:00
