説明

In the following workflow, unstashed messages are enqueued in the mailbox but are not processed as expected:

Send message (messageOne) from TestKit to TestActorRef
TestActorRef underlying actor stashes messageOne and schedules a subsequent message to self (selfMessage)
selfMessage is sent and processed and messageOne is unstashed during processing of selfMessage
messageOne is not processed
Send another message (messageTwo) from TestKit to TestActorRef
Both messageOne and messageTwo are processed

akka.testkit.CallingThreadDispatcher#runQueue appears to process the provided MessageQueue at the time of invocation rather than using the active Mailbox MessageQueue.

明確さ: mostly clear
前提条件: Akka fundamentalsUnderstanding of actor mailboxKnowledge of CallingThreadDispatcher
初心者向け度: 20
調査方針: Investigate the implementation of CallingThreadDispatcher.runQueue method and its interaction with the Mailbox's MessageQueue. The issue suggests that runQueue processes the provided MessageQueue instead of the active one. Compare with the expected behavior and check if there are any related changes in the codebase. Consider looking at the stashing mechanism and how messages are unstashed during self message processing.
