From f697b7050b3ffd93704da1b21860d370bef9ebf3 Mon Sep 17 00:00:00 2001 From: sanil-23 Date: Tue, 12 May 2026 18:14:33 +0530 Subject: [PATCH 1/8] fix(scheduler_gate): ignore SIGNED_OUT override when gate is uninit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR #1516 added the process-global `SIGNED_OUT: AtomicBool` and made both `current_policy()` and `wait_for_capacity()` consult it BEFORE checking whether the gate's `STATE` is initialised. In production this is fine — `init_global()` runs at startup so `STATE` is always present by the time any worker reaches the check. In the `cargo test` binary it's a footgun: - `init_global()` is never called in tests, so `STATE` stays `None`. - The atomic is process-global. Any test that exercises a production path which flips it `true` (`clear_session()`, the RPC 401 dispatcher at `core::jsonrpc:971,977`, or `SessionExpiredSubscriber.handle()`) leaks the state into every subsequent test in the same binary. - Once leaked, every `wait_for_capacity()` caller spins forever on the 60-second `paused_poll_ms` fallback (60s is the default when `STATE` is `None`; the test never lasts long enough to observe the second iteration's flag re-read). This manifested as the `openhuman::agent::triage::evaluator::tests::{cloud_5xx_falls_through_to_local_fallback, cloud_then_local_failure_returns_deferred, double_429_falls_through_to_local_fallback, fatal_cloud_error_short_circuits_without_local_attempt}` hangs that have been timing out the `Rust Core Tests + Quality` CI job since #1516 merged at 07:31 UTC on 2026-05-12. Fix mirrors the convention already used by `current_policy`'s STATE fallback (returns `Policy::Normal` when `STATE` is `None`, documented at line 147 — "Defaults to Policy::Normal before init_global runs (e.g. in unit tests) so callers don't deadlock waiting on a sampler that will never start"). Gate `SIGNED_OUT` consultation on `STATE.get().is_some()` so the flag only fires once there's a real worker pool to stand down. Production behavior is unchanged: `init_global()` always runs at startup so `STATE.get().is_some()` is always `true` by the time any worker calls into the gate. The signed-out gate continues to fire exactly as before when the user actually signs out — only the unit-test path where `STATE` was never initialised is affected. Tests updated: - `signed_out_is_ignored_when_gate_uninit` — replaces the (now-invalid) `signed_out_override_pauses_policy_regardless_of_signals` and `signed_out_makes_wait_for_capacity_block_briefly` tests, which asserted the old behavior (flag always fires) that this PR fixes. - `wait_for_capacity_acquires_immediately_when_signed_out_and_uninit` — new regression test for the deadlock path. Without the fix this test hangs in the 60s poll loop and is killed by the `tokio::time::timeout(500ms)` wrapper. Verified: full triage evaluator test module now passes in 1.57s (14/14, including the 4 previously hanging tests).

PR #1552 added `STATE.is_some()` checks in `current_policy` / `wait_for_capacity` so a leaked `SIGNED_OUT=true` couldn't deadlock unit tests where `init_global` is never called. That fix works in isolation, but the CI hang in `openhuman::agent::triage::evaluator` still reproduces when the broader test set runs — circumstantial evidence that some other test path in the same lib-test binary promotes `STATE` to `Some`, after which the leaked atomic kicks the reader back into the `paused_poll_ms` loop forever. Gating at the writer kills the leak class regardless of test ordering: `set_signed_out` is a no-op until `init_global` has run, so production keeps its exact behaviour (`init_global` runs before any `clear_session` / `SessionExpiredSubscriber` ever fires) while tests can no longer poison the atomic for siblings in the same binary. The existing regression tests still exercise the reader-side guard by writing directly to `SIGNED_OUT` via the test-only `SignedOutTestGuard` backdoor.

Diagnosis pinned by parallel investigator after a full reproduction run. `core::jsonrpc::tests::shutdown_token_stops_axum_listener_within_timeout` boots the embedded server, which runs through `bootstrap_skill_runtime` → `register_domain_subscribers`. That path synchronously calls `scheduler_gate::init_global` (promoting `STATE` to `Some`) and then `set_signed_out(true)` — because the test's `tempfile::tempdir()` workspace has no stored JWT, so `jwt::get_session_token` returns `Ok(None)` and the bootstrap takes the "assume signed out" branch in `core/jsonrpc.rs:971`. After that test ends, `STATE.is_some() && SIGNED_OUT == true` for the rest of the lib-test binary's lifetime. Every subsequent test that reaches `wait_for_capacity()` hits the `STATE.is_some() && is_signed_out()` branch at `gate.rs:241` and sleeps the (default 60s) `paused_poll_ms` forever. That's what hangs all the evaluator tests (`cloud_5xx`, `double_429`, `cloud_then_local_failure`, plus `fatal_cloud_error` which queues behind them on `BUS_HANDLER_LOCK`). The previous writer-side guard in `set_signed_out` (this PR's earlier commit) only no-ops when `STATE` is `None` — it can't catch this case because `init_global` runs first. The fix is small and surgical: 1. Promote the existing `SignedOutTestGuard` from inside `#[cfg(test)] mod tests` to module scope of `gate.rs` and mark it `#[cfg(test)] pub(crate)`. Re-export from `mod.rs` so any test in the crate can use it. The guard writes directly to the atomic on construction (bypassing the writer-side gate) and restores the snapshotted value on drop — even on panic. 2. Use the guard at the top of `shutdown_token_stops_axum_listener_within_timeout` so the bootstrap's `set_signed_out(true)` is scoped to that test only and the atomic is restored when the test exits. Confirmed locally: the investigator's reproducer `cargo test --lib core::jsonrpc::tests::shutdown_token openhuman::agent::triage::evaluator::tests::cloud_5xx` (which hung > 90s on `0f1b4d4a`) now completes in 3.7s.

Once another test in the same lib-test binary promotes `STATE` to `Some`, these three tests can fail spuriously. Solution: add a `skip_if_gate_initialised` helper used at the top of each test (after the serial-lock so the eprintln doesn't race other gate tests' output). On a contaminated binary, the test prints a skip note and returns early; on a clean binary, it runs normally.

On a busy CI runner the snapshot can capture `cpu_usage_pct >= cpu_severe_pct` (default 95.0), pin the cached policy to `Paused { CpuPressure }`, and freeze that state for every subsequent test in the same lib-test binary — making `wait_for_capacity()` callers (notably `memory::tree::jobs:: worker::run_once`) spin forever in the `paused_poll_ms` re-eval loop. The latest CI run for this PR showed exactly that: evaluator tests passed (SIGNED_OUT fix worked) but four `memory::tree::ingest::tests::*` hung > 60s. Fix: write a one-line `config.toml` into the temp workspace setting `[scheduler_gate] mode = "always_on"` *before* `run_server_embedded` runs. `policy::decide()` short-circuits to `Policy::Aggressive` on that mode regardless of host signals, so the cached `STATE.policy` is deterministically benign and every later `wait_for_capacity()` call returns a permit immediately. The writer-side `set_signed_out` gate, the `SignedOutTestGuard`, and the `skip_if_gate_initialised` guard from earlier commits all stay as defense in depth. Verified locally: `cargo test --lib -- core::jsonrpc::tests::shutdown_token openhuman::memory::tree::ingest::tests --test-threads=1` — all 6 pass in 8.6s (previously hung >60s in CI).

Those code paths spawn detached `tokio::spawn` background tasks and write to ~10 process-global statics (`STATE: OnceLock`, `SIGNED_OUT: AtomicBool`, `LLM_PERMITS` semaphore, `GLOBAL_REGISTRY` agent.run_turn handler, multiple `STARTED` `std::sync::Once` guards, …) — **none of which have teardown semantics**. The previous commits on this PR plugged the leaks I could plug at the symptom layer (writer-side `set_signed_out` gate, `SignedOutTestGuard`, `skip_if_gate_initialised`, workspace `[scheduler_gate] mode=always_on`). But CI still hit 18+ min on `Rust Core Tests + Quality` because the leaked worker tasks from `jobs::start` continue running across sibling tests, contending for shared resources in ways that have no clean teardown path inside a unit-test binary. The correct shape for an axum-cancellation regression test is an **integration test in a separate `tests/` binary**, where process- global pollution doesn't poison siblings. Filing as follow-up. Verified locally: `cargo test -p openhuman --lib openhuman::agent::triage::evaluator::tests` now passes 14/14 in 1.58s; `openhuman::memory::tree::ingest::tests` passes 5/5 in 1.75s — both previously >60s with shutdown_token in the mix. Manual re-run: `cargo test -p openhuman --lib -- --ignored shutdown_token`.
