* Update Span API event methods
Remove the context argument from the event methods. It is unused and can
be added back in as a passed option if needed in the future.
Update AddEvent to accept a required name and a set of options. These
options are the new EventOption type that can be used to configure a
SpanConfig Timestamp and Attributes.
Remove the AddEventWithTimestamp method as it is redundant to calling
AddEvent with a WithTimestamp option.
Update RecordError to also accept the EventOptions.
* Add changes to CHANGELOG
* Add LifeCycleOption
Use the LifeCycleOption to encapsulate the options passed to a span for
life cycle events.
* Move trace API to otel
* Move tracetest to oteltest
* Update package documentation
* Remove old api/trace package

* Update codes to match specification
* Add changes to changelog
* go mod tidy
* Add unit tests for codes
* Update SetStatus methods to only filter Unset
* Update apitest code being tested
* Move api/baggage to the propagators package
* Create Baggage API to match specification
* Update CHANGELOG.md
* Baggage API unit tests
* Rename and add unit test
* Update unit test value checking
* Update TODO with issue tracking work.
* Rename *Provider names
There is overlap in naming with MeterProviders and TracerProviders. This
is means the specification is not implemented and these types can not
exist in the same package (#1179). This makes each type and related
functions and types explicit.
* Add changes to CHANGELOG
* Convert XConfigure into constructors
Previously, we discussed the possibility of converting
the config types into internal ones. But due to the
cyclic dependencies it introduces, we are only
converting XConfigure into constructors and document that
XConfig types are most likely are not going to be directly
used by developers.
In package documents, constructors will be nicely listed
under the config types and they won't be yet another
standalone symbol developers need to learn about.
Fixes#1130.
* Add the changes to the CHANGELOG
* Unexport NoopXXX trace types
The change unexports the noop implementations and provide the NoopProvider function for user to construct noop providers. Users can access noop tracer and noop spans by using the provider.
This change removes the types users should never be directly using from the package. It improves the usability of the API by reducing the API surface to half and helping the user to focus on the canonical APIs.
Fixes#1133
* Provide noop tracer and span for internal use
* Remove obsolete doc
* Use noop span instead of nil
* Fix the broken build
* Unify API Span Start/End Options
Replace both with `SpanOption`. Add a unified `SpanConfig` to match and
a `SpanConfigure` function to parse a `SpanConfig` from `SpanOption`s.
Update all the related options to use new `SpanOption`s.
* No non-zero SpanConfig defaults
The SDK uses an internal clock for the current time that cannot be use
if it does not know the time has not been set.
* Append attributes for WithAttributes
This preserves existing behavior.
* Add unit test for SpanConfigure
* Propagate changes
* Update append option documentation
* Update testing comments
* Move comments on guarantees to appropriate function
* Add documentation for SDK methods
Include SDK implementation specific information in the Tracer Start
method and Span End method.
* Add changes to Changelog
* Apply suggestions from code review

* Move proto to OTLP exporter
* Update OTLP exporter import of proto
* Use gogo protobuf
To stop using the deprecated github.com/golang/protobuf and match what
the collector is doing, switch to generating OTLP with the
github.com/gogo/protobuf/proto instead of
github.com/golang/protobuf/proto.
* Clean dependencies
Remove all protobuf dependencies from otel package and all of its
dependencies.
* Update CHANGELOG
* Clean OTLP exporter go mod
Remove submodule beforehand to avoid unneeded direct dependencies.
* Use default ref for GitHub workflow
* Update path that triggers proto gen action
* Correct license-check exclusion for OTLP
* Update commented location of the OTLP and code
* Add otel/codes package to replace google.golang.org/grpc/codes
* Replace google.golang.org/grpc/codes with otel/codes
* Update opentracing bridge to use OTel codes
* Update semconv to use OTel codes
* Update SDK to convert from OTel codes to gRPC
* go mod tidy
* Add change to CHANGELOG
* Fix word from feedback
* Clean stale indirect dependency requirements
In the recent changes to isolate the main `otel` package there were many
indirect dependencies of the package that were removed, however, the
go.mod was not automatically cleaned of these. This removes those (and
similar ones in the otel-collector example and otel exporter) and prunes
the go.sum files accordingly.
* Run in a clean system to reproduce build
* Make opentracing bridge into own Go module
* Update dependabot config
* Clean dependencies of project
Now the bridge is a module, clean all upstream modules that no longer
implicitly depend on it.
* Update Changelog
* go mod tidy
* Update Tracer API with instrumentation version
Add option to the `Provider.Tracer` method to specify the
instrumentation version.
Update the global, noop, opentracing bridge, and default SDK
implementations.
This does not propagate the instrumentation library version to the
exported span. That is left for a follow-on PR.
* Revert trace_test.go
This is for the next PR.
* Update SDK to include version for default instrumentation
If the instrumentation library name is empty and the default
instrumentation is uses, include the SDK version.
* Update comments and documentation
* Remove default instrumentation version
* Point to the convenience functions in api/key package
This is to increase the visibility of the api/key package through the
api/core package, otherwise developers often tend to miss the api/key
package altogether and write `core.Key(name).TYPE(value)` and complain
at the verbosity of such a construction. The api/key package would
allow them to write `key.TYPE(name, value)`.
* Use the api/key package where applicable
This transforms all the uses of `core.Key(name).TYPE(value)` to
`key.TYPE(name, value)`. This also should help increasing the
visibility of the api/key package for developers reading the otel-go
code.

* Update License header for all source files
- Add Apache 2.0 header to source files that did not have one.
- Update all existing headers dated to 2019 to be 2020
- Remove comma from License header to comply with the Apache 2.0
guidelines.
* Update Copyright notice
Use the standard Copyright notices outlined by the
[CNCF](https://github.com/cncf/foundation/blob/master/copyright-notices.md#copyright-notices)
* Propagate context changes in mix tests
We will need this for testing the correlation context and baggage
items propagation between the APIs.
* Add baggage interoperation tests
The test adds a baggage item to active OT span and some correlation
key value to current Otel span. Then makes sure that the OT span
contains both the baggage item and some translated version of the
correlation key value its Otel sibling got, and that the Otel span
contains both the correlation key value and the baggage item its OT
sibling got.
* Add hooks functionality to baggage propagation
This introduces two kinds of hooks into the correlation context
code.
The set hook gets called every time we set a Map in the context. The
hook receives a context with the Map and returns a new context.
The get hook gets called every time we get a Map from the context. The
hook receives the context and the map, and returns a new Map.
These hooks will be used for correlation context and baggage items
propagation between the Otel and OT APIs.
* Warn on foreign opentracing span
* fixup for using otel propagators
* Add utility function for setting up bridge and context
This prepares the context by installing the hooks, so the correlation
context and baggage items can be propagated between the APIs.
* Add bridge span constructor
So I do not need to remember about initializing a newly added member
in several places now.
* Propagate baggage across otel and OT APIs
This uses the set hook functionality to propagate correlation context
changes from Otel to OT spans by inserting keys and values into the
baggage items. The get hook functionality is used to propagate baggage
items from active OT span into the otel correlation context.
* Use correlation Map for baggage items
We will put this map into the context with correlation context
functions, and that is easier if we have correlation.Map, not
map[string]string.
* Use otel propagators in bridge
The otel propagators are now kinda sorta usable for opentracing
bridge. Some more work is needed to make it fully work, though -
correlation context set with the otel API is not propagated to OT
spans as baggage items yet.
