Inline comments:
In `@crates/perry-ext-http/src/client_events.rs`:
- Around line 454-486: Update the upgrade-event handling after collecting
upgrade_listeners so that when the list is empty, any nonzero socket_handle is
destroyed via perry_ext_net::js_ext_net_destroy_socket, then finish the request
and fire its close event before returning. Preserve the existing
listener-dispatch path unchanged.
In `@crates/perry-ext-http/src/client_upgrade.rs`:
- Around line 82-92: Update the request serialization around dispatch_request to
detect whether headers contains a case-insensitive “Host” key before writing the
URL-derived host_header. Emit the fallback Host header only when no
caller-supplied Host exists, while preserving the existing header iteration and
content-length tracking.
- Around line 161-172: Use a single absolute request deadline in the client
upgrade flow, including the connection/header operation and the non-101
response-body drain. Define the deadline with tokio::time::Instant, use
timeout_at for the initial future, and wrap the drain loop in timeout_at using
the same deadline rather than resetting the full duration. Return the existing
timeout error when the drain exceeds the deadline, ensuring the response is
delivered without retaining ClientInflightGuard indefinitely.
- Around line 166-170: Update the read loop in dispatch_upgrade_http_request so
only Ok(0) ends draining the non-101 response; propagate stream.read errors as
an Err result instead of emitting a partial PendingHttpEvent::Response. Preserve
successful body accumulation for Ok(n) reads.
In `@crates/perry-ext-http/src/lib.rs`:
- Around line 510-511: Update scan_http_roots to visit
req.request_create_connection with visit_i64_slot when it is nonzero, ensuring
the closure pointer remains rooted before invoke_create_connection_closure
dispatches it.

site:nodejs.org/api/http.html ClientRequest upgrade event no listener socket closed
💡 Result:
<search_synthesis>
According to the official Node.js documentation for the http module, if a client receives a response with a status code of 101 Switching Protocols (indicating an upgrade) but there is no listener registered for the 'upgrade' event on the ClientRequest object, the underlying socket will be closed [1]. This behavior occurs because the 101 Upgrade status breaks from the traditional HTTP request/response chain [1]. Consequently, for the connection to remain open after an upgrade response is received, a listener for the 'upgrade' event must be attached to the ClientRequest [1].

Destroy the adopted socket when no 'upgrade' listener exists.
adopt_upgraded_tcp_stream registers the socket in perry-ext-net and starts a read task. The no-listener path currently only finishes the request. It does not destroy socket_handle, so the stream can remain open until the peer closes it. Node closes a 101 connection when the client has no 'upgrade' listener.
let upgrade_listeners = with_handle_mut::<ClientRequestHandle, _, _>(request_handle, |req| {
take_request_event_listeners(req, "upgrade")
})

Emit the URL-derived Host only when the caller did not supply one.
headers_from_options preserves a caller-supplied Host value, and dispatch_request passes that map to this serializer. The current code emits both the URL-derived Host and the caller's Host, which creates an invalid HTTP/1.1 request. The caller's Host must override the URL-derived fallback.

Bound the non-101 drain read with the request deadline.
The current timeout covers only connection, writes, and header reads. A non-101 response then drains to EOF without a timeout. A persistent server connection can therefore prevent 'response' from being queued while the task retains ClientInflightGuard.
The separate client timer may still deliver 'timeout', so the failure is delayed response delivery and retained in-flight state. Use one absolute deadline for both operations. Do not reuse the full Duration for the drain.
🐛 Proposed fix: use the remaining request deadline
- let deadline = std::time::Duration::from_millis(timeout_ms.unwrap_or(30_000));
+ let deadline = tokio::time::Instant::now()
+ + std::time::Duration::from_millis(timeout_ms.unwrap_or(30_000));
...
- let (stream, buf) = match tokio::time::timeout(deadline, fut).await {
+ let (stream, buf) = match tokio::time::timeout_at(deadline, fut).await {
...
let mut stream = stream;

Propagate read errors while draining non-101 responses.
In dispatch_upgrade_http_request, Err(_) is treated as EOF. The function then emits PendingHttpEvent::Response with partial body data. handle_response_event constructs the message with complete: true, so a truncated response is reported as complete instead of reaching the caller as a transport error.
match stream.read(&mut chunk).await {
- Ok(0) | Err(_) => break,
+ Ok(0) => break,
+ Err(e) => return Some(Err(e.to_string())),

Root request_create_connection in scan_http_roots. The request stores this closure pointer and later passes it to invoke_create_connection_closure. Because scan_http_roots does not visit the field, a GC before dispatch can leave the pointer stale and cause an invalid closure call.

…omplete/rawHeaders
…calls build_raw_headers_array (res.rawHeaders, #10467) held its result array's raw pointer in a plain local across alloc_string/js_array_push calls that can allocate and therefore collect, moving the array out from under it -- the unrooted-local-shape ratchet caught this going from 1 to 6 findings in this file. Root arr through TransientRootScope::root_nanbox and re-derive via .get() after every allocating call instead of reusing the pre-call copy, matching the pattern already used elsewhere in this crate. Also fixes the same pre-existing shape in build_response_headers_object's set-cookie array builder (unrelated to this PR's diff), extracted into its own top-level build_set_cookie_array so the rooting lines stay short enough that rustfmt doesn't wrap the let binding across lines -- which had been hiding it from the scanner's line-oriented detection. unrooted_local_shape.py --check: 558 (was 561 pre-PR; response_headers.rs per-file ceiling drops from 1 to 0).

Summary
Three separate
node:http/node:httpsclient-side defects, shipped together because #10468 and #10469 bothtouch
dispatch_request_over_socket/PendingHttpEvent::Response, which #10467 extends with two new requiredfields (
http_version,complete) — splitting them into independent PRs would mean either duplicating thatstruct/enum surgery across PRs or artificially stacking them for no independent review value. The three
defects themselves are unrelated (see below); this is "share an implementation surface," not "share a cause."
#10467 — client response missing
rawHeaders/httpVersion/httpVersionMajor/httpVersionMinor/completeNone of these existed on the client
IncomingMessageaccessor surface(
crates/perry-ext-http/src/client_surface.rs) or the codegen native table(
crates/perry-codegen/src/lower_call/native_table/http_server.rs). Added:IncomingMessageHandlegainshttp_version: (u8, u8)andcomplete: bool, threaded through every responseconstruction path (
handle_response_event— sync,complete: trueat construction;handle_response_head_event— streaming,
complete: falseuntilhandle_response_end_eventflips it; the raw-socketdispatch_request_over_socketpath; and the newclient_upgrade.rspath for node:http client never emits 'upgrade': a 101 Switching Protocols response is delivered as 'response' and the socket is lost #10468).reqwest::Response::version()→(major, minor)for the pooled path; the manual HTTP/1.1 status-line parser(
plain_client::parse_http_response, shared by the trailer-aware bypass and theagent.createConnectionsocket path) now also extracts it.
js_http_response_raw_headers/_http_version/_http_version_major/_http_version_minor/
_complete, wired into both the codegen native table (typed access) andperry-stdlib's dynamic dispatch(
dispatch_client_incoming_property, untyped/any-typed access).Caught in review, fixed same-PR: the codegen table swap for
httpVersion/httpVersionMajor/httpVersionMinor/
completereplaced the only entries that routed to the server-sideIncomingMessageaccessors(
js_node_http_im_http_version*/js_node_http_im_complete) — server and client share oneclass_filter: "IncomingMessage"native-table namespace. Without a fallback, every server-sidereq.httpVersion/req.completewould have silently started reading the client stub's hardcoded default (
"1.1"/false) instead of the realvalue. Added the same client-first-then-server-fallback shape the pre-existing
headers/trailersentriesalready use (
server_incoming_property), and added a same-process server+client regression test(
main_server_regress.tsin the validation below) to prove it.Known remaining gap, not fixed here:
rawHeaderson the pooled (reqwest) transport reports lower-caseheader names, not the origin server's original wire casing.
http::HeaderName(thehttp/hyper/reqweststack) normalizes every header name to lower case before Perry ever sees it — there is no way to recover the
original casing from that API.
res.headers,rawHeaders' values, and everything else about the shape (array,correct pairing, duplicates un-merged) are correct. Filing
Part of #10467rather thanFixesfor this reason;full case fidelity would need a transport-level rewrite (bypass reqwest for the default path), which is out of
scope here.
#10468 — client never emits
'upgrade'reqwest consumes a
101 Switching Protocolsresponse as an ordinary body and never exposes the connection, sothere was no way to hand a raw socket back to
req.on('upgrade', (res, socket, head) => ...). New moduleclient_upgrade.rs: an upgrade request (Connection: Upgrade, plainhttp://only — TLS upgrade isn'timplemented, falls through to the normal path) speaks HTTP/1.1 over a raw
TcpStream(same shape as theexisting trailer-aware bypass in
plain_client.rs), and on101adopts the stream viaperry_ext_net::adopt_upgraded_tcp_stream(the same mechanism the server side's raw-upgrade path uses) insteadof reading to EOF. New
PendingHttpEvent::Upgrade+client_events::handle_upgrade_eventfire(res, socket, head)with Node's exact argument shape —headis always aBuffer(neverundefined, evenzero-length, matching Node). Verified end-to-end against a real raw-socket upgrade server:
'upgrade'fires withthe right status/headers,
socket.writeworks, and inbound data delivery also works(
socket.on('data', ...)receives bytes the server sends after the handshake) — so this does not inherit#10471's "adopted socket never delivers
'data'" symptom; that bug is specific to the server-side adoptionpath this PR doesn't touch.
Checked whether this shares a root cause with the two server-side upgrade issues, #10470 and #10471, since the
task asked: it does not. #10470/#10471 are about
crates/perry-ext-http/src/server/raw_upgrade.rsandserver/upgrade.rs— a completely different code path (server accepting an upgrade vs. client requesting one).This PR touches neither file. Not closing them.
#10469 — request-level
createConnectionoption ignoredoptions.createConnection(distinct fromagent.createConnection) was never read — only the Agent-leveloverride was. New
agent::request_create_connection_from_options(mirrors the existingagent_handle_from_options— a closure doesn't survive theoptionsJSON round-tripparse_options_objectdoes, so this reads the NaN-boxed field straight off the original object) threadedthrough all three request-construction entry points (
request_common/get_common/request_overload) into anew
ClientRequestHandle.request_create_connectionfield.dispatch_request_snapshotnow checks it exactlywhen
agent_handle == 0(Node: "used ... when theagentoption is not used"), taking the same raw-socket paththe Agent-level override already used. Refactored the
try_create_connection_socket/build_connect_optionspair (
agent.rs) to takeOption<Handle>so the request-level path can share them without anAgentHandletopull
keepAlivedefaults from (Node's own default here:keepAlive: false).Caught in review, fixed same-PR: my first cut called
build_connect_options(...)(which allocates) beforerooting the closure pointer, instead of rooting it first like the original #2154 code did — a GC during that
allocation could have moved the closure out from under the un-rooted raw pointer copy. Restructured so the
TransientRootScopeis entered and the closure pointer rooted beforebuild_connect_optionsruns, in both theAgent-level and request-level call paths (shared
invoke_create_connection_closurehelper).Validation
