[Ben Hsu [:HoPang]]

I believe it has something to do with that :(

Let me investigate this. At this moment, I am very curious about the 15 failures last week. They all happened on osx, does that lead to anything helpful to solve this bug?

Comment 4

[Ben Kelly [:bkelly, not reviewing]]

The mac-specific failures are probably just a timing issue.  Do you have rr setup locally at all?  Maybe this would reproduce under rr chaos mode.

Comment 5

[Ben Hsu [:HoPang]]

Thanks, let me find a mac machine and setup an rr on it.

Comment 6

[Ben Hsu [:HoPang]]

Oh, I just find out that we don't have rr for osx now, I am now falling back to my Linux...

Comment 7

[Ben Kelly [:bkelly, not reviewing]]

Yea, I meant maybe rr chaos on Linux would trigger similar race condition we see on Mac.  Sorry for my confusing comment.

I ran across this and was excited to see work was being done on this already!  Thanks for jumping on it.

Attachment: Preserve the precision of a timestamp when converting it to string

Hi Ben, and sorry again for not being able to reproduce this.

After thinking this case over, I humbly think the root cause is the precision
of the timestamp is too low  which is 10^-2 sec in the testcase. By applying
this patch, we can make the precision reach to 10^-6 sec. Since it does no harm
to anything, I suggest we land this patch and checko how it would help.
