Description of your changes
This PR introduces new logic to the
captureLambdaHandler()Middy middleware offered by Tracer to allow it to close and restore any open segments whenever another middleware down in the stack returns early.This is made possible by the
cleanupMiddlewaresfunction shipped incommonsin the previous release. The new logic sets a reference to a cleanup function in the Middy internal storage using a scoped key. This way, Middy middlewares that want to return early can call thecleanupMiddlewaresfunction which will execute all the cleanup functions available. This is useful for those middlewares like Idempotency, that want to return a result bypassing the Lambda handler and the normal Middy request lifecycle.I have also added a unit test case to verify that the cleanup logic is executed.
