* Move connection logic into grpcConnection object
If we will need to maintain more than one connection in future, this
splitting off will come in handy.
Co-authored-by: Stefan Prisca <stefan.prisca@gmail.com>
* Make another channel a signal channel
There is another channel that serves as a one-time signal, where
channel's data type does not matter.
* Reorder and document connection members
This is to make clear that the lock is guarding only the connection
since it can be changed by multiple goroutines, and other members are
either atomic or read-only.
* Move stop signal into connection
The stop channel was rather useless on the exporter side - the primary
reason for existence of this channel is to stop a background
reconnecting goroutine. Since the goroutine lives entirely within
grpcConnection object, move the stop channel here. Also expose a
function to unify the stop channel with the context cancellation, so
exporter can use it without knowing anything about stop channels.
Also make export functions a bit more consistent.
* Do not run reconnection routine when being stopped too
It's possible that both disconnected channel and stop channel will be
triggered around the same time, so the goroutine is as likely to start
reconnecting as to return from the goroutine. Make sure we return if
the stop channel is closed.
* Nil clients on connection error
Set clients to nil on connection error, so we don't try to send the
data over a bad connection, but return a "no client" error
immediately.
* Do not call new connection handler within critical section
It's rather risky to call a callback coming from outside within a
critical section. Move it out.
* Add context parameter to connection routines
Connecting to the collector may also take its time, so it can be
useful in some cases to pass a context with a deadline. Currently we
just pass a background context, so this commit does not really change
any behavior. The follow-up commits will make a use of it, though.
* Add context parameter to NewExporter and Start
It makes it possible to limit the time spent on connecting to the
collector.
* Stop connecting on shutdown
Dialling to grpc service ignored the closing of the stop channel, but
this can be easily changed.
* Close connection after background is shut down
That way we can make sure that there won't be a window between closing
a connection and waiting for the background goroutine to return, where
the new connection could be established.
* Remove unnecessary nil check
This member is never nil, unless the Exporter is created like
&Exporter{}, which is not a thing we support anyway.

AddEvent with a WithTimestamp option.

* 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
* 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
http.ResponseWriters may implement additional interfaces
(http.CloseNotifier, http.Flusher, http.Hijacker, http.Pusher,
io.ReaderFrom) that get lost when the ResponseWriter is wrapped in
another object. This change uses the httpsnoop package to wrap the
ResponseWriter so that the resulting object implements any of the
optional interfaces that the original ResponseWriter implements as
well as using the replacement ResponseWriter methods that gather
information for tracing.
* 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

is actually needed.

Services to run the zipkin client along with a zipkin collector:

$ docker-compose up zipkin-collector zipkin-client
Since the zipkin collector takes a few seconds before it is ready to
receive traces, I added a simple retry loop to the client command.
The collector service exposes port 9411 so user can visit
http//localhost:9411/ to see the trace sent to the collector. Be sure to
search by the trace id logged by the client.

* 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.

* Add zipkin exporter
The zipkin exporter implements the SpanBatcher interface. It follows
the current-at-the-time-of-writing document about conversion from
OpenTelemetry span data to Zipkin spans. Which means that endpoint
information is not yet filled.
* Fix typo in docs
* Add a zipkin example
This sends span information to a locally running zipkin collector.
Currently I have a problem getting the collector to show me the spans
after accepting them with HTTP 202. Not sure if this is because of
missing endpoint information.
* Make gitignore consistent
The fixed paths should be prefixed with a slash. The "relative" paths
mean that git will ignore all the files that end with the path.
