William Kennedy f075821cbb Update histogram_test.go
These tests are always timing out in our Jenkins CI environment. We have moved our timeout to 2 minutes. I have added a check for the short flag so other can skip these tests as we are until this can be identified.

William Kennedy a794f77b54 Update go_collector_test.go
We are running into a timeout with TestHistogramConcurrency on our Jenkins box. I noticed in the stack trace for the timeout this block.

goroutine 2348 [chan send]:
github.comcast.com/ventris/kober/vnd/github.com/prometheus/client_golang/prometheus.(*goCollector).Collect(0xc20801e8e0, 0xc20800a7e0)

This suggested that even though the TestGoCollector test was finished, a goroutine was still hanging around. I traced it back to the call to c.Collect always sending twice of the provided channel. This change receives that second value and allows the goroutine to finish with the test.

Still can't figure out why TestHistogramConcurrency is timing out after 2 minutes :(

beorn7 59f2c7d8b0 Fix a number of minor things.
- Clarify documentation about sorting requirements.
- Add missing histogram support in consistency check.
- Add label sorting to consistency check.
- Improve error messages when reporting a metric.
  (Previously, the metric name was not printed.)

Tomasz Elendt dd4dd69878 Solve "The Proxy Problem" of InstrumentHandler
InstrumentHandler provides proxy object over given http.ResponseWriter
- responseWriterDelegator that only implements the bare minimum
required of an http.ResponseWriter and doesn’t implement any interface
upgrades (http.Flusher, http.Hijacker, etc.). This commit fixes it by
providing fancyResponseWriterDelegator with all the fancy bells and
whistles if standard library http.ResponseWriter is detected.

Heavily inspired by Goji's middleware.

Tobias Schmidt 765c1152ca Rename process_goroutines to go_goroutines
The decision was made to use the language name for language specific
metrics, so go_goroutines is the right names similar to
go_gc_duration_seconds.

Julius Volz 21b7c6b048 Always build the procfs collector.
The cgo dependency in the "procfs" package is being removed in:

  https://github.com/prometheus/procfs/pull/4

So now it should be fine to always import the "procfs" package and have
it determine dynamically at runtime whether the proc filesystem is
actually there.

This fixes a problem for users which were vendoring client_golang on
MacOS X, but building the result on Linux (the procfs package was
missing in the vendored packages).

beorn7 a762e0612e Allow the metric family injection hook to merge with existing metric families.
If a metric family returned by the injection hook already exists (with
the same name), then its metrics are simply merged into that metric
family. With enabled collect-time checks, even uniqueness is checked,
but in general, things stay the same that the caller is responsible to
ensure metric consistency.

This fixes https://github.com/prometheus/pushgateway/issues/27 .

Julius Volz 738b69e61a Use non-rewritten Godep imports. 2015-02-27 16:49:40 +01:00
Julius Volz 169c8a68e1 Use godep with import rewriting for vendoring.
The new vendoring was produced by running:

    godep save -r ./examples/... ./prometheus/... ./text/... ./model/... ./extraction/...

Two things to note:

- "extraction/processor0_0_{1,2}_test.go" imported a package from
  "github.com/prometheus/prometheus", all for just one tiny testing
  function. To not have to deal with a circular vendoring dependency, I
  simply replaced the usage of the function by some in-line logic.

- godep grouped the rewritten imports slightly differently for some
  reason, but at least the standard library imports are still in a
  separate section. Not sure if it's worth manually keeping our old
  import grouping scheme or if we should simply use that godep-generated
  one.
