Buildkite has not started for this fork PR. Could a maintainer approve the fork CI run when convenient? The new regression fails on the unfixed runtime for the default HTTPS policy, passes its explicit-true control, and both cases plus the full surrounding file pass on the locally built exact head as described in the PR body. |

Rebase oven-sh#42855 onto 9bd19c9. Retain current listener generations and close state while applying the HTTPS half-open policy.
Use a TLS client that sends FIN so both half-open modes exercise the same end/close sequence under Node 24.

Rebased onto 9bd19c98e. Retained listener generations and socket close state while applying the HTTPS half-open policy. The regression now uses graceful TLS FIN and matches Node 24.21.0 in both modes. On macOS, the CONNECT file went from 81 passing / 1 failing to 82 passing / 0 failing (1 skip, 2 todos); the neighboring HTTP file passed 283 tests before and after (1 skip). |

Remove the fixture’s fixed deadline.
A slow runner can hit the deadline even when the socket closes correctly. The test still detects a missing-close regression: server.close() runs only from the socket’s close handler, and the test awaits the subprocess exit. If the socket does not close, Bun’s test timeout catches the hanging test.
Suggested fix
- const deadline = setTimeout(() => {
- console.error("upgrade socket did not close");
- process.exit(1);
- }, 2000);
let request;
...
- clearTimeout(deadline);

What does this PR do?
Bun's Node HTTP server socket always hardcodes
allowHalfOpen: true. That matches Node for plain HTTP, butnode:httpsinheritstls.Serversemantics: HTTPS sockets default tofalseand preserve an explicitallowHalfOpen: trueoption.The mismatch leaves an HTTPS upgrade socket writable after its peer sends FIN. A WebSocket origin that waits for
closestays alive until the server timeout, while Node closes it immediately.Record the server's Node-compatible half-open policy and apply it to encrypted HTTP sockets. Plain HTTP keeps its existing always-half-open handoff behavior. The regression covers both the default and explicit-true variants in fresh subprocesses.
This was found while running OpenClaw's full test matrix directly under Bun. It blocks prompt cancellation and WebSocket cleanup from settling in Bun-hosted HTTPS fixtures.
AI-assisted: the investigation, implementation, and validation were assisted by Codex.
