Fix float64 comparison test failure on archs using FMA (#1133)
* Fix float64 comparison test failure on archs using FMA

Architectures using FMA optimization yield slightly different results so
we cannot assume floating point values will be precisely the same across
different architectures.

The solution in this change is to check "abs(a-b) < tolerance" instead
of comparing the exact values. This will give us confidence that the
histogram buckets are near identical.

* copy float compare dependency

Per discussion in the pull request, we'd like to avoid having an extra
dependency on a float comparison package. Instead, we copy the float compare
functions from the float comparison package.

The float comparison package we're choosing is this. The author of this
package has commented in the pull request and it looks like we have consensus
that this is the best option.

* remove float32 variant, relocate into separate file

This change removes the float32 variant of the AlmostEqual funcs, that we will
likely never use. This change also relocates the function into a separate file
to avoid modifying a file that's a fork of another vendored package.

sparse buckets: Fix handling of +Inf/-Inf/NaN observations
2022-10-11 12:57:40 +02:00
beorn7 6942f9e454 sparse buckets: Fix handling of +Inf/-Inf/NaN observations
NaN observations now go to no bucket, but increment count (and
effectively set sum to NaN, too).

±Inf observations now go to the bucket following the bucket that would
have received math.MaxFloat64. The former is now the last bucket that
can be created.

The getLe is modified to return math.MaxFloat64 for the penultimate
possible bucket.

Also add a test for getLe.

Rafael Franco 7c46c150bd
Clarify documentation around what constructors do (#1125)
The wording of the documentation is slightly misleading. Before this
commit, it says that the returned collectors are "already registered".
This could be interpreted in two ways, one could think that promauto
keeps some sort of cache of already registered Collectors that are
returned by this package, and the other way is that the Collectors
constructed are registered before being returned. What is actually
happening is the latter, and the wording after this PR leaves no room to
think that the former could be the case.

Extend prometheus.Registry to implement Collector (#1103)
* prometheus: implement Collector interface for Registry

This change allows Registries to be used as Collectors.

This enables new instances of Registry to be passed to ephemeral
subroutines for collecting metrics from subroutines which are still
running:

```go
package main

import (
  "fmt"

  "github.com/prometheus/client_golang/prometheus"
)

func main() {
  globalReg := prometheus.NewRegistry()

  for i := 0; i < 100; i++ {
    workerReg := prometheus.WrapRegistererWith(prometheus.Labels{
      // Add an ID label so registered metrics from workers don't
      // collide.
      "worker_id": fmt.Sprintf("%d", i),
    }, prometheus.NewRegistry()

    globalReg.MustRegister(workerReg)

    go func(i int) {
      runWorker(workerReg)

      // Unregister any metrics the worker may have created.
      globalReg.Unregister(workerReg)
    }(i)
  }
}

// runWorker runs a worker, registering worker-specific metrics.
func runWorker(reg *prometheus.Registry) {
  // ... register metrics ...
  // ... do work ...
}
```

This change makes it easier to avoid leaking metrics from subroutines
which do not consistently properly unregister metrics.
