* 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the EXAMPLES variable was out of date - the stackdriver example wasn't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
Jaeger exporter was replaced with stdout exporter in the example, so
update the README to reflect that. Also drop the screenshot - it's not
referenced anywhere.
* 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.
* rename finish -> end
* missed a few finish -> end spots
* change end back to finish for the bridge span in the openTracing bridge
* fixed grammar, ran make
* 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.
* add propagation api.
* add http propagator interface and w3c propagator implementation.
* remove Extract api from trace.
* remove Extract interface for tracer.
* fix copyright.
* fix variable names and comments.
* move inject/extract out of trace.
* replace INVALID_SPAN_CONTEXT with EmptySpanContext function.
* fix tag.Map.
* make carrier as interface instead of http.Request.
* rename structs and update doc comments..
* add doc.go
* update doc.
* add noop propagator.
* add new propagation api with Supplier interface.
- added Default Tracer which simply propagates SpanContext.
- added CopyOfRemote option to simply create remote span.
* remove old propagator.
* rename propagator to TextFormatPropagator.
* rename default tracer/span as pass_through tracer/span.
* add test for pass through tracer.
* add missing interface to pass through tracer.
* return SpanContext instead of contex.Context from Extract interface.
- also remove PassThroughTracer
* fix review comments.
* add more test cases for traceContext extraction.
* remove tidy temporarily from circle-ci target to avoid build failure.
* allow header ending in dash '-'.
* add inject test for non-zero value other than 01 for traceoption
* add AddLink and Link interface to MockSpan
* fix running go mod tidy on every build.
* 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
* Move scope.Active to trace.CurrentSpan
* Remove scope / does not build
* Global tracer
* Checkpoint
* Checkpoint
* Add key/key.go for key.New
* Comments
* Remove more EventID and ScopeID
* Use Handle to describe static objects
* TODOs
* Remove empty file
* Remove singletons
* Update TODOs
* TODO about map update
* Make stats package option aliases (like key has)
* Rename experimental/streaming
* streaming SDK builds w/ many TODOs
* Get the examples building
* Tidy up metric API / add interface check
* Remove logic from the registry; this is now a placeholder
* fix compile errors.
* fix lint errors.
* add circle-ci job.
* rename IDHigh to TraceIDHigh
* rename the file.
* add go get for goimports and golangci-lint
* enable GO111MODULE and remove comments.
* remove working dir and update cache name
* Add TEST_RESULT env back.
* run go mod tidy.
* remove go mod download.
* add test coverage.
* fix TraceID.
* fix circlefi config error.
* remove install-tools.
* remove ALL_TEST_SRC from Makefile.
* rename Log and Logf interface to AddEvent and AddEventf.
- also remove log package.
* provide only AddEvent interface to Span
- Event can be created using Event specific interface.
* add var trick for Event interface.
