@guozhangwang @bbejeck @vvcephei Should we change this to "zero or negative" ? Comparing the implementation, passing in a negative timestamp will "expire" the timeout even without checking the state transition at all and return immediately (with
false
) even if the state transition was successful.There was a problem hiding this comment.

I'm fine with those semantics, maybe we can make a Jira.
Thinking about it more, though, wouldn't it make more sense to:
ofYears(1)
orofMillis(Long.MAX_VALUE)
or some other intuitively "long enough to be forever" value instead of a magic value.Regardless, I agree the current behavior is a little weird, and I'd be in favor of a Jira/KIP to revise it.

Overall I'm ok with the semantics.
But my first instinct of a timeout of
0
implies shutdown immediately with no wait and blocking forever takes a value ofLong.MAX_VALUE
.In short, I'm +1 as well on revising the behavior.

I think, we should fix this in 2.1 -- I am suggestion this, because we could use the new semantics for
close(Duration)
only and stay with old semantics forclose(long, TimeUnit)
-- if we don't so this, it would be an backward incompatible change and thus we could only do it in3.0.0.

@nizhikov Are you willing for address 7477 in this PR? If not, it's also fine and we do a follow up PR. However, it should be part of the KIP description. Could you update the KIP accordingly?

As far as I can understand thus fix is trivial.
I'm planning to provide PR in a 24 hour after this PR finish. Is it OK?

Wouldn't call it trivial, but sure, this sound good! Thanks a lot. Just want to make sure we get it on time to not miss code freeze deadline. Thanks a lot!
