There is the possibility for a race in the test, where the outbound socket buffer is still being filled, after 5 seconds, when the main test thread tries to close the resource scope.
The test has been updated to set the send/receive buffer sizes in an attempt/hint to limit the accepted/connected socket buffer sizes. Actual buffer sizes in use will likely be larger due to TCP auto-tuning, but the hint typically reduces the overall scaled sizes. This is primarily to stabilize outstanding write operations. Additionally, to ameliorate the wait-for-writebuf-to-fill situation, the dumb sleep 5secs has been replaced with a heuristic that checks that the number of bytes written quiesces. With these changes, the test successfully passes several thousands of runs. ------------- Commit messages: - initial changes Changes: https://git.openjdk.java.net/jdk17/pull/30/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk17&pr=30&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8268342 Stats: 52 lines in 1 file changed: 46 ins; 4 del; 2 mod Patch: https://git.openjdk.java.net/jdk17/pull/30.diff Fetch: git fetch https://git.openjdk.java.net/jdk17 pull/30/head:pull/30 PR: https://git.openjdk.java.net/jdk17/pull/30
