Thanks! I think we miss only the python upgrade tests for 3.0
{quote}Because back porting that fix to 3.x would be its own effort, so I felt
it was out of scope for this ticket. That behavior has been around for a long
time so if you were bitten by it... upgrade to 4.0? =D
{quote}
While we often agree to not backport something, I am not sure that is what the
community wants here? If we are going to silently ignore this bug in our tests,
I would like to see some visibility and common agreement on that.
My concerns – the original ticket is critical and mentions the bug affects
availability but it doesn't even mention that the issue exists on previous
versions. I is said it is there since 4.0? While I absolutely do not expect
fixing the problem or porting the patch here as part of this ticket, I am not
sure we should just decide to silence it. Probably [~maedhroz] can comment
better as the person most familiar with that problem.
