# ThreadSanitizer suppressions for FairMQ.
#
# libzmq is not built with -fsanitize=thread, so tsan cannot observe the
# happens-before that its inproc/socket queues establish between the user
# threads and libzmq's I/O threads. This produces false-positive data races
# on message buffers handed across that boundary. The proper fix is to build
# libzmq with tsan as well; until then these races are suppressed.

# Racy access made directly from libzmq (encoder/decoder memcpy,
# signaler/epoll, recv).

# Zero-copy message deleters that libzmq runs from msg_t::close once it is
# done with a buffer; the happens-before with the buffer's producer runs
# through libzmq's queue.
