3a9c80c56f Provide conformance tests for tracers (#191)
* Provide conformance tests for tracers

The test harness may be used to ensure that a given tracer behaves
according to the expectations set by the API.

* Add `ToMatchError` matcher

* Use DeepEqual to compare unknown types in matchers

Unlike basic `==`/`!=`, `reflect.DeepEqual` can compare arbitrary
types (e.g., `[]string` to `[]string`)

* Use struct instead of string for test context key

I decided to remove constructors for some of the propagation types

or a single, non optional member.

f863bfbd86 rename noop_meter.go to noop.go (#180)
The file defines noopMeter, noopHandler and noopLabelSet. Renaming it to
the more generic `noop.go` makes it clearer that several structs are

9ed97980e2 Add Stackdriver Trace exporter for trace. (#160)
* Add Stackdriver Trace exporter for trace.

TODOs for future work is:

* to replace bundler.Bundler

* to add proper tests for the exporter

* to move the exporter to proper repository once it will be created.

* Change to use functions for the exporter initialization instead of
passing option struct directly.
This fix is aliging the same fix for Jaeger (#146, #161)

* Change Option struct to be function type

* Change the original Option struct to be private

* Add line comments to maxMessageEventsPerSpan to leave it for future implementation

* Fix unnessesary expressions specified by `make precommit`

Left errors by `make precommit` in experimental/bridge/opentracing.

* Ran make precommit

* Add new line at EOF

* WIP: Start implementing BatchSpanExporter interfaces

* Change to use RegisterSpanProcessor to register bsp

* Change function names to fit current implementation of sdk

* Removed google.golang.org/api/support/bundler and implement ssp and bsp

* Change spanProcessor as a member of Exporter.

* Fix option names used for BatchSpanProcessor initialization.

* Change Exporter.Shutdown just to unregister spanProcessor.

* Removed copyright statements of OpenCensus.

* Fix small typo and EOF new line

* Fix interfaces of ExportSpan/ExportSpans to meet SpanSyncer/SpanBatcher

* Change to follow context.Context passed in ExportSpan/ExportSpans

* Fix Stackdriver Exporter to hold sync.Once to lock when it is registered and
unregistered.

be8fb0b4e2 Golang metrics prototype (#100)
* initial metrics work

* rename cumulative to counter

* rename bidirectional to nonmonotonic

* rename unidirectional to monotonic

* rename nonnegative to signed

this changes the default semantics a bit - before the change measure
could record negative values by default, now it can't.

The specification draft currently specifies both NonNegative and
Signed, but I think it's a mistake.

* rename instrument to descriptor

* license

* rework measurement values

* make measurement value a tagged union

* simplify to one kind of metrics

* add observers

* change some interfaces to match the spec

* keep integral measurement separate from floating ones

* remove duplicated measurement type

* add checking for options

* reorder some fields and functions

* rename a function

to avoid confusion between the Handle type and the Measure type

* drop disabled field from descriptor

* add back typed API for metrics

* make metric options type safe

* merge alternatives into a single bool

* make value kind name less stuttery

* fix observation callback prototype

* drop context parameter from NewHandle

* drop useless parameter names

* make descriptor an opaque struct

* use a store helper

* handle comment fixes

* reword Alternate comment

* drop the "any value" metrics

* make measurement value simpler

* document value stuff

* add tests for values

* docs

* do not panic if there is no span ID in the event

c2d5c66990 Export package (#162)
* setup sdk exporter package

* use sdk exporter package in sdk trace

* use sdk exporter package in all exporters

* empty the exporters list before testing Load

* move SpanData to the exporter package

* use the SpanProcessor registration, don't register exporters

* rename exporter structs to avoid stutter

* rename Syncer and Batcher to SpanSyncer and SpanBatcher

So it's explicit they are for spans, and we reduce the risk of name
conflict

* remove not moot todo

* rename sdk exporter to export

* only execute the SpanData if it is sampled

d351eb4de2 Http interceptors (#156)
* WIP

* Finish http middleware implementation

This is currently done as httptrace.NewHandler(). This should maybe
be moved to a different package or renamed, but atm this name
seemed the least objectionable to me.

There are a few TODOs sprinkled in the code for questions I didn't
know the answers to.

There is an example provided, which when copied to a main func
locally work against the jaeger all in one.

Real tests need to be added.

* Address feedback

* Tie in propagation, update attributes, more options, revise example, etc.

Dropped the httpConfig type because it seemed redundant an unecessary
abstraction.

* WithRouteTag

* address out of band feedback

* move to othttp package

* Add a very basic test.

I ended up needing to export the Traceparentheader const so that
it was accessible to this test.

* Add file header

a936b8fb00 Add some docs about useful step before filing a PR (#151)
* Add a document about contributing

It is shamelessly stolen from opentelemetry-python and edited to be
relevant to opentelemetry-go. This file should explain some less
obvious things about the development of the project, like running
linters and regenerating the files.

* Force the use of go modules

Until go 1.13 modules were disabled by default if the repository was
inside GOPATH. This was causing issues when running `make precommit`
for the first time, as it could not find sources for any of the tools
used in `make precommit` under `${GOPATH}/src`. With setting the
`GO111MODULE` environment variable to `on`, we tell `go` to behave
differently, just like go 1.13 does by default.

339ca2d974 Initial opentracing bridge (#98)
* Allow specifying custom timestamps for events

Adding event with timestamp is not yet a part of the OpenTelemetry
specification, but this function will come in handy when implementing
the OpenTracing bridge.

* Add opentracing bridge, wrapper tracer and migration interfaces

There are some features missing - setting up links and span kind;
context propagation will only work between two OpenTracing bridges.

* Add some tests for the opentracing bridge

The tests mostly check various aspects of the cooperation between
OpenTracing and OpenTelemetry APIs.

3362421c9b Drop the registry package (#130)
This is to shrink the PR #100.

The only place where the registry.Variable type was used was metrics,
so just inline that type into its only user. The use of the
registry.Variable type in core.Key was limited to the Name field.

The stats package also used the registry.Variable type, but seems that
also only the Name field was used and the package is going to be
dropped anyway.
