Motivation: FileSourceSpec dispatcher checks can select a stale fileSource child left briefly by a previous materialization, which makes the dispatcher override assertion flaky. Modification: Capture existing fileSource children before starting each dispatcher-check stream, wait for exactly the newly materialized child, and watch it terminate after cancellation. Result: The checks assert the dispatcher of the stream started by the current test instead of a leftover child from an earlier materialization. Tests: - JDK 17 Scala 3.3.6: stream-tests / Test / testOnly org.apache.pekko.stream.io.FileSourceSpec - scalafmt --mode diff-ref=origin/main --quiet - scalafmt --list --mode diff-ref=origin/main - git diff --check References: Refs apache#2994

动机： FileSourceSpec 调度程序检查可以选择先前物化短暂留下的陈旧 fileSource 子级，这使得调度程序覆盖断言不稳定。 修改： 在启动每个调度程序检查流之前捕获现有的 fileSource 子项，等待新具体化的子项，并观察它在取消后终止。 结果： 这些检查断言当前测试启动的流的调度程序，而不是早期物化中剩余的子级。 测试： - JDK 17 Scala 3.3.6：流测试/测试/testOnly org.apache.pekko.stream.io.FileSourceSpec - scalafmt --mode diff-ref=origin/main --quiet - scalafmt --list --mode diff-ref=origin/main - git diff --检查 参考文献： 参考号apache#2994
