Every node:net socket, listener and TLS session already ran on the agent's turnloop loop; the tokio socket task survived only as the fallback for a thread that does not own its agent's loop. That thread now posts its submissions to the owner (perry_ffi::agent_post), the two tokio timers become loop deadlines, and an HTTP upgrade's stream is adopted onto the loop through a new turnloop_net::adopt_stream ABI.
Re-record scripts/tokio_inventory.json (17 -> 15 edges) and rewrite the remaining group-A blockers; classify turnloop_io's DEADLINES table in scripts/gc_runtime_root_holders.json.

Record the local-connect reservation only after connect_pipe succeeds.
When connect_pipe fails after note_local_connect, refuse_connect cancels the server reservation but does not remove the Aux entry. The refusal path does not call emit_close_once, so the entry remains.
This is an Aux memory leak for each failed connect_pipe call. Net socket IDs are not freed on close, so the stale-reservation collision with a reused ID is not reachable through the current ID lifecycle.
The TCP path records the reservation only after a successful connect. Use the same ordering here.

Report posted TLS upgrade failures through submission_failed on both synchronous paths.
The posted path queues Error and Close directly. It does not request tl::close or set errored. The JS socket state is then removed while the turnloop handle can remain live. Later driver completions can arrive for that handle. Later terminal or error processing can also emit duplicate events.
submission_failed(handle, 0, error) records one error, destroys the handle, and lets NET_CLOSED emit the close event.
The owner-inline caller at crates/perry-ext-net/src/tls.rs:875-878 has the same defect and needs the same change. The js_net_socket_upgrade_tls path is different: it passes a JsNativeAsyncCompletion token, and begin_client_upgrade rejects that token on failure. Keep that Promise-settlement path separate from submission_failed.
Proposed fix
let posted = crate::turnloop_io::post_to_owner(Box::new(move || {
if let Err(error) =
crate::turnloop_tls_io::begin_client_upgrade(handle, servername, verify, config, None)
{
- crate::push_event(crate::PendingNetEvent::Error(handle, error));
- crate::push_event(crate::PendingNetEvent::Close(handle));
+ crate::turnloop_io::submission_failed(handle, 0, error);
}
})); } else if let Err(error) = begin_tls_upgrade(handle, servername, verify, config) {
- crate::push_event(crate::PendingNetEvent::Error(handle, error));
- crate::push_event(crate::PendingNetEvent::Close(handle));

new net.Socket()starts withawaiting_connect: true. A pre-connectsocket.write()reachesSocketState::command, incrementsbytes_queued, and returns success without retaining theSocketCommand::Write. The later connect path clearsawaiting_connect, but no connect path replays that command. The payload is therefore lost even though the write was accepted.The previous implementation sent writes to
cmd_tx; the deferred socket retainedpending_rx, andrun_socket_taskconsumed those commands after the transport connected. Replace the current counter-only branch with an ordered pending-command queue. Drain it after successful connect submission through the normal turnloop command path, and clear it on refused connects. Do not change the separate TLS-upgrade behavior.🤖 Prompt for AI Agents

Main moved perry-ext-net off tokio (#11105): the two tokio connect paths and the ipc open sites are gone, adopt.rs and turnloop_io.rs gained one each, so the measured population is 6, not 7. turnloop_io::on_connect sets has_opened in a second block on purpose (a failed direct-TLS upgrade must not record the socket as opened), registered as a documented exception.

Based directly on
main(d8f24f15ed), with main's turnloop 0.1.0-alpha.6 pin unchanged. The only turnloop APIs this uses —Detached::from_fd(Unix),Detached::from_socket(Windows) andDriver::attach— are all in alpha.6; nothing here needs alpha.7+.Part of the tokio removal, group A of
scripts/tokio_inventory.json.What this removes
perry-ext-net → tokioandperry-ext-net → tokio-rustls.python3 scripts/tokio_inventory.py: 17 → 15 manifest edges; group A 4 → 2.Cargo.lockloses only those two dependency lines (both packages are still used elsewhere, so the lockfile package count stays at 14).Why it was still there
Every
node:net/node:tlssocket, listener and TLS session already ran on the agent's turnloop loop. tokio survived for four reasons, and each has a replacement here:perry-native). It now posts its submissions to the owner throughperry_ffi::agent_post(the P10 route; 19 of the 29 remaining tokio edges are one problem: the decline path, and turnloop's Poster is the missing half #10395's "one binding converted end to end as the proof" — this is that binding). Both threads serve the same JS heap, so completions land where the socket's JS values live.turnloop_io::on_loopis the one routing point: inline on the owner (what every call site did before), posted otherwise. The one case posting cannot serve is a host where turnloop'sLoop::newfailed; there the operation fails withENOTSUPthrough the socket's normal'error'/'close'path instead of running on a second event loop.'connection'deferral (server_state::schedule_server_connection) and the 25 ms pre-abortedtls.connectsignal (tls::schedule_tls_abort). Both are turnloop deadlines now (turnloop_io::arm_deadline, delivered asNET_TIMERto this crate's sink). Each uses a fresh handle id that is freed when it fires, because the runtime keys deadlines per thread across subsystems.adopt_upgraded_tcp_stream(tokio::net::TcpStream)— the HTTP raw-'upgrade'handoff. New runtime ABIturnloop_net::adopt_stream(js_perry_net_adopt_stream; perry-ffiturnloop_net::adopt_stream) puts an already-connected fd/SOCKET on the agent's loop via turnloop'sDetached::from_fd/from_socket+Driver::attach, reading the endpoints off the descriptor first.adopt_upgraded_tcp_streamnow takes astd::net::TcpStream(the two perry-ext-http callers dostream.into_std()). The caller is a tokio worker thread that must never claim a loop, so the stream is parked and a job posted;ensure_adopted_socket_dispatch— which the HTTP side already calls from its upgrade-event drain before any listener runs — completes pending adoptions inline on the owner, so JS never sees a socket the loop has not adopted.Transport/run_socket_task/ per-socketmpscchannels that the fallback needed. Deleted (transport.rs,task_spawn.rs, the tokio accept loops inlib.rs/ipc.rs,tls::do_tls_handshake/record_tls_handshake, and the unusedconnect_tls_clientAPI whose last caller left with perry-ext-ws's migration).SocketState::pending_rxbecameawaiting_connect: bool,ServerState::shutdown_txbecamelisten_armed: bool, with the exact semantics the channel ends encoded.The inventory's group-A blockers were stale; fixed
The remaining group-A rows (
perry-ext-http → hyper,hyper-util) said they were held by (a) the P1 coexistence rule and (b) "turnloop'sDriverhas no API that adopts a foreign fd" for the SCHED_RR cluster worker'sspawn_rr_inject_loop. Neither is a blocker any more: (a) is the posting route above, with perry-ext-net as the worked example; (b) was already false (turnloop hasDriver::attach(Detached)since alpha.6 andDetached::from_listener_fdsince alpha.8) and perry-runtime now exposes it asturnloop_net::adopt_stream. The rows now say what is actually left — deleting the hyper accept loops, the raw-'upgrade'peeler and the RR inject loop, feeding RR descriptors throughadopt_streamintoturnloop_serve— and why this PR did not do it: #11084 is rewritingraw_upgrade.rs/upgrade.rs/server.rson that hyper path right now. This PR touchesraw_upgrade.rsin one call expression (stream.into_std()beforeadopt_upgraded_tcp_stream), outside #11084's hunks.Behaviour
Same status on every test below, base vs branch (see Validation). Two intentional differences, both off every path a test or a normal program takes:
ENOTSUPinstead of falling back to tokio.socket.upgradeToTLS()on a socket that never connected rejects withsocket is not connectedimmediately (it used to hang until the parked command channel was dropped, then reject withupgrade reply dropped).socket.setNoDelay()is now an explicit chainable no-op. It already was on every turnloop socket (turnloop fixesTCP_NODELAYat creation and has no live socket-option call); only the deleted tokio task could apply it, so the fivenodelay_teststhat droverun_socket_taskover tokio are deleted with it, as isipc::tests::unix_socket_stream_round_trip, which tested the deleted tokioconnect_path.buffer_pool's real-socket differential test is rewritten onstd::netagainst the sink's actual copy-out path;deferred_connect_agrees_with_turnloop_availabilitybecamedeferred_connect_reaches_the_loop_on_every_route(asserts all three routes);lifecycle's two byte-accounting tests use the newSocketState::for_test(awaiting_connect).Validation
