Merge pull request #1144 from prometheus/beorn7/histogram2 
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.

Robert Fratto 83d56b1144
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.
