9f03360a84 Enable golint & gofmt, resolve issues (#214)
* Add golint to linters and resolve issues.

I decided to remove constructors for some of the propagation types
because the constructors can be reduced to either using the zero value
or a single, non optional member.

* Enable gofmt and commit fixes

3516ebc456 Rename IsRecordingEvents and WithRecordEvents (#188)
Since these methods are about the span itself rather than specifically
*events* on the span, it makes sense to drop "events" from their names.

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

7966e63342 More cleanups from #100 (#142)
* Drop dead event type

* Replace EventType from reader with one from exporter

* Do not concat the strings for string buffer

* Fill scope ID in events

That required renaming a variable, because it had the same name as the
type we wanted to assert later.

* Do not fail quietly when span context is busted

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.

a776e95c61 Consolidate AddEvent and Event methods, add FinishOptions (#99)
* Merge two event methods in span API

There was an agreement to get rid of the Event interface and
consolidate the two methods for adding events into one. See #57.

* Eliminate the use of the Event interface

There is no need for the SDK to provide the implementation of the
Event interface - it is used nowhere.

* Drop the Event interface

It's dead code now.

* Make it possible to override a finish timestamp through options

Opentracing to opentelemetry bridge will certainly use this feature.

* Obey the start time option

* Add tests for events and custom start/end times

670b0365d8 Make tag.Map a concrete type. (#89)
This is to make tag.Map an immutable type, so it is safe to use
concurrently. The safety is not yet fully achieved because of the
functions returning contents of the map (Value and Foreach). The
functions give callers an access to core.Value objects, which contain
a byte slice, which has pointer like semantics. So to avoid accidental
changes, we will need to copy the value if it is of BYTES type.

Fixes #59

fafb3daf1e Fix parent span ID formatting (#103)
It was printing an ID of the created span instead. Also drop the if
clause checking if span has a parent span ID - we know at this point
that the condition is always true.

8d93efab11 Run go generate during make and make sure that generated files are in sync in CI (#101)
* Run go generate in the precommit target

So we should always get an updated version of a file generated by a
stringer utility.

* Update the generated file

* Make CI to fail if working tree has uncommited changes

The uncommitted changes may come from the golang linter (that formats
our code among other things) and from stringer (when updated some
enumeration).
