fix(net): support named-pipe and Unix-socket IPC - #8718
Conversation
📝 WalkthroughWalkthroughThe net runtime adds Unix-domain socket and Windows named-pipe support for path-based clients and servers. Socket connect APIs now forward raw overload arguments and return socket handles. Shared transport, lifecycle, connection accounting, TLS validation, and standalone test shims are updated. ChangesNet IPC transport
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The change adds local IPC support, but the current implementation can permanently stop a Windows named-pipe server after a transient accept error and can mishandle a callback pointer if garbage collection occurs during connection setup. These create concrete availability and runtime-correctness risks, so the PR is not ready to merge until addressed. Sequence Diagram(s)sequenceDiagram

socket.connect(port, host)a POINTER_TAG string, this branch reportshost = None. The code then connects to127.0.0.1and treats the host string as the connect callback.register_connect_cbwould store a StringHeader pointer as a callback.Confirm the two paths accept the same set of host encodings.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
A transient Windows pipe error terminates the whole IPC server.
Line 289 uses connected? and line 294 uses create_pipe_server(&path, false)?. Each propagates the error out of run_listener. spawn_listener then pushes ServerError and ServerClose, and sets listening = false. One transient failure therefore stops the named-pipe server permanently.
The two sibling accept loops do the opposite. The Unix arm at lines 232-237 reports ServerError and continues. The TCP loop in crates/perry-ext-net/src/lib.rs at lines 848-855 states the rule explicitly: it does not break on a transient accept error because Node does not. Make the Windows arm match.
🐛 Proposed fix
connected = listener.connect() => {
- connected?;
+ if let Err(error) = connected {
+ push_event(PendingNetEvent::ServerError(
+ server_id,
+ format!("accept: {error}"),
+ ));
+ continue;
+ }
let stream = listener;
// A Windows named-pipe instance accepts exactly one client.
// Create the next instance before publishing the accepted one
// so concurrent connectors do not observe a needless gap.
- listener = create_pipe_server(&path, false)?;
+ listener = match create_pipe_server(&path, false) {
+ Ok(next) => next,
+ Err(error) => {
+ push_event(PendingNetEvent::ServerError(
+ server_id,
+ format!("accept: {error}"),
+ ));
+ return Err(error);
+ }
+ };Note: a failure to create the replacement instance is genuinely fatal, because the loop has no listener left. Keep that one terminal, but report it as an accept error first so the shape matches the Unix arm.

Root the connect callback before the allocating work in spawn_socket.
ipc::spawn_socket(path) runs next_id_or_throw, allocates an unbounded channel, and inserts into statics::sockets() and statics::listeners(). Only after it returns does ipc::register_connect_cb(handle, arg2_f64) store the callback pointer into statics::listeners().
scan_net_roots (Line 270) visits only the pointers already present in listeners() and once_flags(). Until the store happens, arg2_f64 is not a scannable root. If any allocation inside spawn_socket triggers a collection, the moving GC rewrites nothing for that value, and the pointer stored afterwards is stale.
The instance-method path in this same PR gets the order right. Lines 995-998 and 1002-1005 call ipc::register_connect_cb before ipc::connect_existing. Apply the same ordering here by splitting the allocation from the connect.
🛡️ Proposed fix
In crates/perry-ext-net/src/ipc.rs, expose the two phases:
pub(crate) fn allocate_ipc_socket() -> (i64, mpsc::UnboundedReceiver<SocketCommand>) {
allocate_socket()
}
pub(crate) fn start_connect(
id: i64,
path: String,
rx: mpsc::UnboundedReceiver<SocketCommand>,
) {
spawn_connect(id, path, rx);
}Then in crates/perry-ext-net/src/lib.rs:
if let Some(path) = ipc::string_value(arg1_f64) {
- let handle = ipc::spawn_socket(path);
- ipc::register_connect_cb(handle, arg2_f64);
+ let (handle, rx) = ipc::allocate_ipc_socket();
+ ipc::register_connect_cb(handle, arg2_f64);
+ ipc::start_connect(handle, path, rx);
return handle;
}
if is_nanboxed_pointer(arg1_f64) {
if let Some(path) = get_object_string_field(arg1_f64, "path") {
- let handle = ipc::spawn_socket(path);
- ipc::register_connect_cb(handle, arg2_f64);
+ let (handle, rx) = ipc::allocate_ipc_socket();
+ ipc::register_connect_cb(handle, arg2_f64);
+ ipc::start_connect(handle, path, rx);
return handle;
}The same ordering concern applies to the TCP factory calls at Lines 566 and 590, which register after spawn_socket_task. That ordering predates this PR, but the same split fixes it.
As per coding guidelines: "A GC-managed value's root store must dominate every subsequent site that can collect."

…Intl worklist (#8723) Lands #8672, #8718, #8720 and #8659. #8672's blocker is resolved the way the evidence pointed. Its own `is_bound_native_method_closure_value` is gone; only main's `is_bound_native_constructor_closure_value` remains, and the branch that called it in `parent_static.rs` is deleted. That branch was unreachable under either predicate -- the `if let Some(..) = bound_native_callable_ module_and_method(..)` block directly above returns unconditionally, and both predicates require that same query to be `Some` -- so removing it is behaviour-preserving rather than a choice between two semantics. #8718 (closes #6620) routes `server.listen(path)`, `net.connect(path)` and the `{ path }` overloads through real Windows named pipes and Unix-domain sockets instead of falling back to TCP. #8720 stabilizes native value profile boundaries; #8659 completes the Intl 402 test262 worklist. One fix on top: a changelog fragment for #8718, which had neither one nor a skip-changelog label. #8719 is NOT in this batch -- it conflicts with #8672 on `lower_call/method_override.rs`, which both touch.
