* Fix TestExporterShutdown go leak
The shutdown tests checking if a context error is honored did not
completely clean up the resources used by the client after the error was
evaluated. Update the connection client to handle multiple calls to
shutdown and make a second call to these clients that must succeed so
the test does not have abandoned goroutines.
* Fix leak in TestNew_WithTimeout
The mockTraceService did not delay with its lock being held. This
resulted in the mockCollector stopping and being able to acquire the
lock. It was assumed that no export was taking place because of this and
the mockTraceService was abandoned without cleaning up resources it held
and goroutines it had spawned. This reworks the export blocking logic to
block on a channel read. This will make the block more deterministic and
not depend on the scheduler timing. Additionally, this blocking is moved
inside the lock acquire. Meaning code will deadlock if the block is not
released before a shutdown (something the developer will immediately be
aware of when they submit a bad patch), and will ensure all resources
are released before shutdown.
Replace TestNew_WithTimeout with TestExportSpansTimeoutHonored which
directly tests if a span export errors when the timeout is reached. This
is the only unique thing that TestNew_WithTimeout, but it also tests the
non-error path. That non-error path is tested in many other tests.
* Guard otlptracehttp client stopCh when stopping
In normal operations the exporter is guaranteed to only ever call the
client Stop method once. However in testing we need to call this
multiple times when checking it returns an error in particular context.
Add a lightweight sync.Once to the closing of the stopCh to ensure tests
do not panic when cleaning up.
