…cuted manually during release preparation due to those tests failing intermittently in CI
Wait for both sides of an HTTP/2 exchange to terminate before completing it, including graceful request termination after RST_STREAM(NO_ERROR). Cover authentication replay with a large file and with a body-less 401 followed by a graceful stream reset.

@mkurz The test coverage looks awesome! However I need a little while to digest the proposed fix. Please bear with me. |

There was a problem hiding this comment.
@mkurz Your suggested fix is perfectly fine.
For the sake of code consistency could we use the same approach as used in HttpAsyncMainClientExec using AtomicInteger instead of two AtomicBoolean?

This fixes HTTPCLIENT-2433.
When an HTTP/2 authentication challenge completed before the request body had finished,
H2AsyncMainClientExecpreviously notified the execution chain that the exchange was complete immediately. The authentication handler could then release and reuse the same repeatable entity producer while the original HTTP/2 stream was still consuming it, corrupting the replayed request body.The HTTP/2 execution handler now completes the exchange only after both request output and response input have terminated. It also handles a graceful
RST_STREAM(NO_ERROR)after a complete response as request-side termination, allowing authentication replay to continue without hanging.Regression coverage includes:
401followed byRST_STREAM(NO_ERROR), verifying that the authenticated retry completes with the exact 2 MB request body.Reproducer:
