Node's own runtime bit twice today: a one-line dispatcher override that silently downgraded built-in fetch() to HTTP/1.1 is now scoped to upgrades only, and a deferred-close race that aborted sessions with an onread assert is closed at the source.
fix: preserve HTTP/2 for non-upgrade legacy requests nodejs/undici
Dispatcher1Wrapper forced allowH2: false on every request, so any Node.js version whose built-in fetch() consumes undici.globalDispatcher could not negotiate HTTP/2. mcollina restricts that HTTP/1.1 compatibility override to upgrade requests, keeps the native WebSocket fallback on HTTP/1.1 with an asserted protocol, and adds an HTTP/2-only server fixture so the regression cannot return silently.
http2: fix onread assert when destroying session from stream handler nodejs/node
When session.destroy() runs from a 'stream' handler, MakeCallback drains nextTick while nghttp2 is still inside mem_recv, and HEADERS arriving in that window created C++ streams with no JS wrapper or onread, ending in Assertion failed: onread->IsFunction(). The fix rejects new streams while the session is closing and destroys the C++ handle when on_headers runs after close, removing a hard cras...
fix: skip drain dispatch for clientTtl-evicted clients in PoolBase nodejs/undici
Evicted clients in a Pool configured with clientTtl could still emit drain events after close, and kOnDrain would dispatch queued items to them, throwing ClientClosedError. The race is narrow same-region but widens to hundreds of milliseconds with cross-region TLS connection times, which is exactly the deployment shape that will hit it.
perf_hooks: implement SlidingWindowHistogram nodejs/node
The recordable Histogram accumulates samples indefinitely with no notion of time; jasnell's SlidingWindowHistogram keeps the window fixed and bounded, count or time based, over an internal ring buffer of histograms. Snapshotting a bounded window is what makes peak-latency numbers from perf_hooks usable in long-running processes.
test(h2): stabilize http2-connection (#5801) nodejs/undici
The last of the [flaky] http2 test files gets the hardening its siblings already received: the unexpected-disconnect guard ignores the client's own idle-socket teardown after keepAliveTimeout, since the client reconnects transparently, and now lives in test/utils/h2-disconnect-guard.js with coverage. It also swaps per-test RSA-2048 keygen for a static pem. The crowded but routine tail: a v8 ser...
