Merge pull request #567 from prometheus/beorn7/counter 
Make TestCounterAddLarge more robust
 2019-05-04 18:08:04 +02:00
Bjoern Rabenstein bf1f4e4a24 Make TestCounterAddLarge more robust 
The previous `float64(math.MaxUint64 + 1)` is too close to
`float64(math.MaxUint64)` to actually overflow as indended.

The counter code is actually converting forward and backward and
compare the original and twice-converted value. On most platform, this
will create a deviation and thus trigger the expected behavior. By
sheer "luck", one might end up with the same value and thus still use
the uint64 representation. Which is OK within the precision we can
expect. But it breaks the test. With this change, the next
representable floating point value greater than the floating point
value used to represent math.MaxUint64 is used.

Bjoern Rabenstein 1173d73405 Increase minimum required Go version to 1.9 
This allows us to simplify a bunch of code while still supporting the
last four Go minor versions.

We have also run into minor annoyances a couple of times by now to
keep supporting 1.7 and 1.8.

It's time to pull the plug!
