Anon2Tokyo opened a new pull request, #16416: URL: https://github.com/apache/dubbo/pull/16416
## What is the purpose of the change? Fixes #16414. This change fixes the gRPC no-stub method discovery path for Triple streaming requests. The lazy method discovery listener now reuses the stream's existing `StreamingDecoder` instead of creating a temporary `GrpcStreamingDecoder`, so buffered bytes from a subsequent message are preserved when the listener switches to the resolved business handler. The close callback on the temporary method-discovery listener is also made a no-op because it only exists to resolve the method descriptor and should not close the actual request stream. A regression test covers a DATA-frame layout where the first decode contains one complete gRPC message followed by the prefix of the next message, then verifies the second message is still decoded after the listener switch. ## Checklist - [x] Make sure there is a [GitHub_issue](https://github.com/apache/dubbo/issues) field for the change. - [x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [x] Write necessary unit-test to verify your logic correction.
