* Remove otel/sdk dependency from grpctrace
Use otel/trace/testtrace instead and cleanup testing code.
* Update httptrace to not depend on the SDK
Update testing to use api/trace/testtrace instead.
* Add changes to Changelog
* Make the SDK its own Go module
* Upgrade go.mod to 1.14 project wide
* go mod tidy
* Make the stdout exporter its own package
Follow the pattern of the other exporters.
* Update dependabot with stdout exporter
* Add replace directives for stdout exporter
* Remove outdated example test from metric SDK
* go mod tidy
* Update othttp example test
Remove unused stdout exporter.
* Remove tests in API that depend on stdout exporter
The global package does not need to be validated with the SDK. A more
properly constructed end-to-end integration test should be built if this
is actually needed.
* Add replace clause for otel in stdout go.mod
* automate building all the examples
the EXAMPLES variable was out of date - the stackdriver example wasn't
even built
let's automate it, so we don't need to remember about updating the
variable after adding a new example to the examples directory
* move jaeger example to example directory
this should be in the examples directory, so it can be built by the
make test during CI.
* switch to go 1.13
circle ci uses go 1.12 (which is the oldest 1.12 release) that
contains some bugs with module handling
let's switch to go 1.13.3, the latest go currently
* use a single valid revision of the project in go.mod files
this probably shouldn't be a problem since the switch to go 1.13 in
circle ci, but cleans up the mess and the use of bogus releases
