* Push->basic * Repackage * Rename away from push * Make exporter optional; export from a separate goroutine * Move pull_test into controller_test * Precommit pass * New OTLP/Prom example * Precommit * Fix the example * Shorten the example * Test starting controller w/o exporter * Test export timeout * Remove ancient example & lint * go.mod revert & tidy * Comments * Tidy a diff * Tidy a diff * Move export kind selector in the new example * Split this test into its original parts * Reduce diff size * Changelog * Remove extra Add/Done pair * Remove unused stopCh param; document the Stop behavior * Typo * Use ctx * Missed v0.15 * Apply PR feedback * Precommit pass * 0.14 -> 0.15 in new file * Remove diff chunk markers * Fix OTLP example * Upstream * dashpole comments * aneurysm9 feedback * Tidy go.sum
