Subject: [Tarantool-patches] [PATCH v16 0/3] qsync: implement packet filtering (part 1)
Date: Wed, 15 Sep 2021 17:50:43 +0300	[thread overview]
Message-ID: <20210915145046.133303-1-gorcunov@gmail.com> (raw)

Packet filtering takes more and more time to implement and I send
similar patches again multiple times. Still the complete split brain
detection is not yet done, so I thought it might be worth to split the
work into several series. This part addresses a race with terms manipulation
and I think can be considered as its own.

I would really appreciate comments here mostly due to function naming,
comments and etc. My primary aim was to make sure that this series doesn't
break anything existing but I think if we would have a test case for this
ordering issue it would be brilliant, though I didn't come with some simple
one here yet.
