perry-ext-http: createConnection and Agent facade expiry on turnloop; drop the tokio edge (tokio lane D) - #11265
Merged
Merged
Conversation
…-ext-http drops tokio The last two tokio users in perry-ext-http move onto the agent's loop: - the agent.createConnection / createSocket (and request-level createConnection) exchange runs in client_turnloop::raw_socket. Instead of a tokio task polling the raw-net vtable every 1 ms, perry-ext-net calls a new perry_ffi::raw_net_notify when a raw-mode socket gains bytes or goes terminal, and the client drains it on a 0 ms loop timer; - the keep-alive Agent's 40 ms socket-facade idle expiry, and req.setTimeout's early 'timeout', are loop deadlines (push_after). perry-ext-http no longer depends on tokio: cargo tree -p perry-ext-http -i tokio -e normal,dev finds no tokio. tokio inventory: 5 -> 4 edges.

never polls synchronously during net dispatch, including when next_id or
timer_arm fails. Update schedule_raw_drain and the failed ArmTimer handling for
Timer::RawDrain to post the drain with perry_ffi::agent_post::post_job; preserve
retry and rejection handling, and keep the inline fallback for the initial drain
in start_raw_exchange.
- Around line 48-119: When `on_loop` fails in `start_raw_exchange`, close the
already-attached socket via the raw-net vtable before emitting `TransportError`;
preserve the existing error event and its fields.

Close the adopted socket when loop submission fails.
The caller attaches the socket before start_raw_exchange. If on_loop cannot submit the operation, the callback never writes the request. The current branch emits TransportError but leaves the raw-mode socket registered, so the request fails and the live socket can keep the process active.

Defer raw drains from raw_socket_ready, including timer-arm failures.
raw_socket_ready calls run(effects) before route_data or mark_terminal returns. If next_id() returns INVALID_HANDLE, Effect::RawDrain calls poll_read synchronously. If timer_arm fails, conn::on_timer maps Timer::RawDrain to Effect::RawDrain, which is also processed synchronously. This violates RawNetNotify's contract. EOF can therefore call close during net dispatch.
Do not skip the drain. A complete response can already be buffered with no later notification, so skipping it can delay response delivery until the deadline. Post the drain directly with perry_ffi::agent_post::post_job; do not use on_loop, because on_loop executes locally when the current thread owns the loop. Preserve the existing retry and rejection handling.

}Apply the same deferred posting when run handles a failed ArmTimer for Timer::RawDrain. Keep the inline fallback for the initial drain in start_raw_exchange.

Tokio lane D:
perry-ext-httpno longer depends on tokio. Together with #11205 (reqwest, tokio-rustls) and #11144 (hyper), the crate has no tokio-family dependency left, in normal or dev dependencies:tokio_inventory.py --update: 5 → 4 manifest edges (theperry-ext-http → tokiorow is gone). Lockfile packages are unchanged at 6, because tokio itself is still used elsewhere.This was stacked on #11205. #11205 has merged, so it is rebased onto

agent.createConnection/createSocketand request-levelcreateConnection(client_connect_override.rs→ newclient_turnloop/raw_socket.rs)The exchange over the socket JS produced used to run in a tokio task that called the raw-net vtable's
poll_readin a loop, with a 1 mstokio::time::sleepafter every empty read.It now runs on the agent's loop and is event-driven:
raw_net_notify/register_raw_net_notify, a readiness callback beside the existing vtable.raw_bridge::route_data/mark_terminalcallraw_net_notifyafter buffering bytes or marking a raw-mode socket terminal. The lock is released first.RawNetNotify.The socket stays perry-ext-net's, including its connect and TLS state and its JS identity. The exchange is unchanged: one write with
Connection: close, read to EOF, and the sameparse_http_response. A101detaches the socket for'upgrade'. The 30 s default deadline is kept, now as a loop timer.2. The keep-alive Agent's socket-facade idle expiry (

perry_ffi::spawn_async+tokio::time::sleepis nowclient_turnloop::push_after, a loop deadline that queues the event.req.setTimeout's early'timeout'uses the same helper. Neither deadline keeps the process alive by itself.push_afteronly arms a loop deadline on a thread already known to own the loop. Otherwise it falls back to a plain sleeping thread, so scheduling an event can never be what claims the agent's loop route. That matters because the first thread to ask for the route owns it for life.Nothing in the crate calls
perry_ffi::spawn_async/spawn_blocking(_with_reactor)any more. The tests use no tokio: there is no#[tokio::test], no tokio runtime and no tokio dev-dependency.Depends on #11263 for no-auto
createConnectionIn the default auto-optimize mode,
createConnectionworks end to end. A compiled probe (an Agent whosecreateConnectionreturnsnet.connect(port), thenhttp.getthrough it) prints200 Via Your Socket /cc body for GET, byte-identical to Node 26.5.1.Under
PERRY_NO_AUTO_OPTIMIZE=1,createConnectionfails, onmainbefore and after this change. That link carries two copies of perry-ffi and of perry-ext-net, one in the prebuilt net archive and one rebuilt with http, so the raw-net vtable and notify slot are split between them. #11263 makes the no-auto build one cargo invocation, so there is one copy of each crate. Its author confirmedcreateConnectionmatches Node there with this change's code.I tried moving the two raw-net slots into perry-runtime first, and dropped it: with two perry-ext-net copies, http then found the embedded copy's vtable and waited on a socket id that, in that copy's table, is an unconnected Agent facade. It timed out after 30 s instead of failing at once. The single-build fix is the real one. The slots stay in perry-ffi, with their single-instance scope documented.
