beorn7 dba1478b8a Add lint:ignore for protobuf deprecation
`github.com/golang/protobuf/proto` is deprecated in lieu of
`google.golang.org/protobuf/proto`. However, we cannot simply
migrate. Types from the proto package are exposed to users of packages
in this repo. If we migrate here, users have to migrate to. Thus, we
could only migrate with a major version bump.

In different news, with all the inline lint:ignore comments, including
the existing ones, there is no need to repeat the exception in the
Makefile.

A current version of `staticcheck` is happy with the code after this
commit. golangci-lint is broken at the moment, however, and ignores
the lint:ignore comments in the code as well as those via envvar.

beorn7 db9651a839 Add test-short target and use it in CI
This is reinstating the old behavior. The longer tests are not only
long but also flaky. (The former is by design, the latter is a bug.)

Ashish Gandhi 9912488b03 Use spaces instead of tabs to align equals (=)
Using tabs to align things has the downside that people who have set the
tabstop to be of a different lenght than the orignial author's run the
risk of not having the alignment stay. In the current Makefile before
this change people with tabstop of 4 do not see the equals line up.

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.

Bjoern Rabenstein 5d40912fd2 Complete rewrite of the exposition library.
This rewrite had may backs and forths. In my git repository, it
consists of 35 commits which I cannot group or merge into reasonable
review buckets. Gerrit breaks fundamental git semantics, so I have to
squash the 35 commits into one for the review.

I'll push this not with refs/for/master, but with refs/for/next so
that we can transition after submission in a controlled fashion.

For the review, I recommend to start with looking at godoc and in
particular the many examples. After that, continue with a line-by-line
detailed review. (The big picture is hopefully as expected after
wrapping up the discussion earlier.)

Matt T. Proud 7efd34a6f8 Optimize fingerprinting and metric locks.
These are all simple changes we should have caught a long time ago:

1. The hashing mechanism for fingerprint label sets should have not
   allocated new objects for the actual hashing---at least not
   egregiously.  This simplifies the hash writing by just byte-
   dumping the string stream into the hasher.

2. The hashing mechanism within the scope of a metric does not care
   about the value of the label keys themselves but only of the label
   values.  The keys can be dropped from the calculation.

3. The locking mechanism for the metrics should not block on hash
   computation but rather solely on the actual mutation or critical
   section reads.

4. For scalar metrics (i.e., ones with niladic label signatures), we
   should rely on a preallocated map versus requesting a new one
   ad hoc.

This is tested with Go 1.1, so the results may yield other values
for us elsewhere:

BenchmarkLabelValuesToSignatureDouble	 5000000	       574 ns/op	     142 B/op	       5 allocs/op
BenchmarkLabelValuesToSignatureTriple	 5000000	       758 ns/op	     186 B/op	       6 allocs/op

BenchmarkLabelToSignatureDouble	 2000000	       746 ns/op	     174 B/op	       7 allocs/op
BenchmarkLabelToSignatureTriple	 1000000	      1061 ns/op	     235 B/op	       9 allocs/op

In effect, a single metric mutation operation's lookup overhead will
move from Before::iBenchmarkLabelToSignature to
After::BenchmarkLabelValuesToSignature.  This MINIMALLY reduces
1/2 the overhead.  I would be hesitant in reading the memory
allocation statistics, for this was run with the GC still on and
thusly inaccurate per Go benchmarking documentation.

Before::BenchmarkLabelValuesToSignature never existed, so it is not
of any intrinsic value in itself.  That said, the cases that still
rely on LabelToSignature experience consistently a 1/2 drop in time.
