Hi all, We have the intention of deprecating the urcu-signal flavor in the future. We are asking users of URCU for _feedback_ on this before going any further.
Part of this decision is that we are adding support for TSAN in URCU and the signal flavor deadlocks with TSAN. It is also my understanding that the urcu-signal flavor was historically made as a fallback for system lacking the membarrier(2) system call. Nowadays, most systems have support for that system call, making the urcu-signal an artifact of the past. The following is a proposed timeline of events: 1. Asking for feedback from users of URCU (this message) 2. Disabling the signal flavor by default and adding --enable-flavor-signal 3. Removing the signal flavor -- Olivier Dion EfficiOS Inc. https://www.efficios.com _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
