Resetting `_runtime_vars` post-(forking-)spawn was
previously only possible via direct mutation of
`_state._runtime_vars` from an external module + an
inline default dict duplicating the
`_state.py`-internal defaults. Split the access
surface into a pure getter + explicit setter so such
a reset call site becomes a one-liner composition:
`set_runtime_vars(get_runtime_vars(clear_values=True))`.
Deats `tractor/runtime/_state.py`,
- extract initial values into a module-level
`_RUNTIME_VARS_DEFAULTS: dict[str, Any]` constant; the
live `_runtime_vars` is now initialised from
`dict(_RUNTIME_VARS_DEFAULTS)`
- `get_runtime_vars()` grows a `clear_values: bool = False`
kwarg. When True, returns a fresh copy of
`_RUNTIME_VARS_DEFAULTS` instead of the live dict —
still a **pure read**, never mutates anything
- new `set_runtime_vars(rtvars: dict | RuntimeVars)` —
atomic replacement of the live dict's contents via
`.clear()` + `.update()`, so existing references to the
same dict object remain valid. Accepts either the
historical dict form or the `RuntimeVars` struct

Adopt the `@pytest.mark.skipon_spawn_backend('subint',

reproducing the `subint` GIL-contention / starvation
hang classes doc'd in `ai/conc-anal/subint_*_issue.md`.
Deats,

- `tests/test_cancellation.py`
- `tests/test_inter_peer_cancellation.py`
- `tests/test_pubsub.py`
- `tests/test_shm.py`
- Per-test decorator where only one test in the file
hangs:
- `tests/discovery/test_registrar.py
::test_stale_entry_is_deleted` — replaces the
inline `if start_method == 'subint': pytest.skip`
branch with a declarative skip.
- `tests/test_subint_cancellation.py
::test_subint_non_checkpointing_child`.
- A few per-test decorators are left commented-in-
place as breadcrumbs for later finer-grained unskips.
Also, some nearby tidying in the affected files:
- Annotate loose fixture / test params
(`pytest.FixtureRequest`, `str`, `tuple`, `bool`) in
`tests/conftest.py`, `tests/devx/conftest.py`, and
`tests/test_cancellation.py`.
- Normalize `"""..."""` → `'''...'''` docstrings per
repo convention on a few touched tests.
- Add `timeout=6` / `timeout=10` to
`@tractor_test(...)` on `test_cancel_infinite_streamer`
and `test_some_cancels_all`.
- Drop redundant `spawn_backend` param from
`test_cancel_via_SIGINT`; use `start_method` in the
`'mp' in ...` check instead.

(factored: dropped spawn-backend-only path: tests/test_subint_cancellation.py)
A reusable `@pytest.mark.skipon_spawn_backend( '<backend>' [, ...],
reason='...')` marker for backend-specific known-hang / -borked cases
— avoids scattering `@pytest.mark.skipif(lambda ...)` branches across
tests that misbehave under a particular `--spawn-backend`.
Deats,
- `pytest_configure()` registers the marker via
`addinivalue_line('markers', ...)`.
- New `pytest_collection_modifyitems()` hook walks
each collected item with `item.iter_markers(
name='skipon_spawn_backend')`, checks whether the
active `--spawn-backend` appears in `mark.args`, and
if so injects a concrete `pytest.mark.skip(
reason=...)`. `iter_markers()` makes the decorator
work at function, class, or module (`pytestmark =
[...]`) scope transparently.
- First matching mark wins; default reason is
`f'Borked on --spawn-backend={backend!r}'` if the
caller doesn't supply one.
Also, tighten type annotations on nearby `pytest`
integration points — `pytest_configure`, `debug_mode`,
`spawn_backend`, `tpt_protos`, `tpt_proto` — now taking
typed `pytest.Config` / `pytest.FixtureRequest` params.

Add a hard process-level wall-clock bound on a test
known to wedge un-Ctrl-C-ably under an in-dev spawn
backend, so an unattended suite run can't hang
indefinitely.
Deats,
- New `testing` dep: `pytest-timeout>=2.3`.
- `test_stale_entry_is_deleted`:
`@pytest.mark.timeout(3, method='thread')`. The
`method='thread'` choice is deliberate —
`method='signal'` routes via `SIGALRM` which can be
starved by the same GIL-hostage path that drops
`SIGINT`, so it'd never actually fire in the
starvation case.
At timeout, `pytest-timeout` hard-kills the pytest
process itself — that's the intended behavior here;
the alternative is the suite never returning.

Bottle up the diagnostic primitives that actually cracked the
silent mid-suite hangs in the `subint` spawn-backend bringup (issue
there" session has them on the shelf instead of reinventing from
scratch.
Deats,
- `dump_on_hang(seconds, *, path)` — context manager wrapping
`faulthandler.dump_traceback_later()`. Critical gotcha baked in:
dumps go to a *file*, not `sys.stderr`, bc pytest's stderr
capture silently eats the output and you can spend an hour
convinced you're looking at the wrong thing
- `track_resource_deltas(label, *, writer)` — context manager
logging per-block `(threading.active_count(),
len(_interpreters.list_all()))` deltas; quickly rules out
leak-accumulation theories when a suite progressively worsens (if
counts don't grow, it's not a leak, look for a race on shared
cleanup instead)
- `resource_delta_fixture(*, autouse, writer)` — factory returning
a `pytest` fixture wrapping `track_resource_deltas` per-test; opt

the new stdlib `concurrent.interpreters` module

(cherry picked from commit d3d6f646f9)
During the Phase A extraction of `trio_proc()` out of
`spawn._spawn` into its own submod, the
`debug.maybe_wait_for_debugger(child_in_debug=...)` call site in
the hard-reap `finally` got refactored from the original
`_runtime_vars.get('_debug_mode', ...)` (the fn parameter — the
dict that was constructed by the *parent* for the *child*'s
`SpawnSpec`) to `get_runtime_vars().get(...)` (a global getter that
returns the *parent's* live `_state`). Those are semantically
different — the first asks "is the child we just spawned in debug
mode?", the second asks "are *we* in debug mode?". Under
mixed-debug-mode trees the swap can incorrectly skip (or
unnecessarily delay) the debugger-lock wait during teardown.
Revert to the fn-parameter lookup and add an inline `NOTE` comment
calling out the distinction so it's harder to regress again.
Deats,
- `spawn/_trio.py`: `child_in_debug=get_runtime_vars().get(...)` →
`child_in_debug=_runtime_vars.get(...)` at the

add 4-line `NOTE` explaining the parent-vs-child distinction.
- `spawn/__init__.py`: drop trailing whitespace after the
`'mp_forkserver'` docstring bullet.
- `ai/prompt-io/prompts/subints_spawner.md`: drop duplicated `with`
in `"as with with subprocs"` prose (copilot grammar catch).

Split the monolithic `spawn._spawn` into a slim
"core" + per-backend submodules so a future
`._subint` backend (per issue #379) can drop in
without piling more onto `_spawn.py`.
`._spawn` retains the cross-backend supervisor
machinery: `SpawnMethodKey`, `_methods` registry,
`_spawn_method`/`_ctx` state, `try_set_start_method()`,
the `new_proc()` dispatcher, and the shared helpers
`exhaust_portal()`, `cancel_on_completion()`,
`hard_kill()`, `soft_kill()`, `proc_waiter()`.
Deats,
- mv `trio_proc()` → new `spawn._trio`
- mv `mp_proc()` → new `spawn._mp`, reads `_ctx` and
`_spawn_method` via `from . import _spawn` for
late binding bc both get mutated by
`try_set_start_method()`
- `_methods` wires up the new submods via late
bottom-of-module imports to side-step circular
dep (both backend mods pull shared helpers from
`._spawn`)
- prune now-unused imports from `_spawn.py` — `sys`,
`is_root_process`, `current_actor`,
`is_main_process`, `_mp_main`, `ActorFailure`,
`pretty_struct`, `_pformat`
Also,
- `_testing.pytest.pytest_generate_tests()` now
drives the valid-backend set from
`typing.get_args(SpawnMethodKey)` so adding a
new backend (e.g. `'subint'`) doesn't require
touching the harness
- refresh `spawn/__init__.py` docstring for the
new layout

[claude-code-gh]: https://github.com/anthropics/claude-code
The prior approach eagerly reused `_parent_chan` when
parent IS the registrar, but that channel may still
carry ctx/stream teardown protocol traffic —
concurrent `unregister_actor` RPC causes protocol
conflicts. Now try a fresh `get_registry()` conn
first; only fall back to the parent channel on
`OSError` (listener already closed/unlinked).
Deats,
- fresh `get_registry()` is the primary path for
all addrs regardless of `parent_is_reg`
- `OSError` handler checks `parent_is_reg` +
`rent_chan.connected()` before fallback
- fallback catches `OSError` and
`trio.ClosedResourceError` separately

When the parent actor IS the registrar, reuse the existing parent
channel for `unregister_actor` RPC instead of opening a new connection
via `get_registry()`. This avoids failures when the registrar's listener
socket is already closed during teardown (e.g. UDS transport unlinks the
socket file rapidly).
Deats,
- detect `parent_is_reg` by comparing `_parent_chan.raddr` against
`reg_addrs` and if matched, create a `Portal(rent_chan)` directly
instead of `async with get_registry()`.
- rename `failed` -> `failed_unreg` for clarity.

a different uid claims the same addr

Fix type-mixing bug at `_root.py:446` where the
registrar merge path did `set(Address + tuple)`,
preventing dedup and causing double-bind `OSError`.
Wrap `uw_reg_addrs` before the set union so both
sides are `Address` objs.
Also,
- add prompt-io output log for this session
- stage original prompt input for tracking

Allow callers to explicitly declare transport
bind addrs instead of always auto-generating
random ones from ponged registrar addresses.
Deats,
- new `tpt_bind_addrs` kwarg wraps each input
addr via `wrap_address()` at init time.
- non-registrar path only auto-generates random
bind addrs when `tpt_bind_addrs` is empty.
- registrar path merges user-provided bind addrs
with `uw_reg_addrs` via `set()` union.
- drop the deprecated `arbiter_addr` param and
its `DeprecationWarning` shim entirely.
Also,
- expand `registry_addrs` type annotation to
`Address|UnwrappedAddress`.
- replace bare `assert accept_addrs` in
`async_main()` with a descriptive
`RuntimeError` msg.

Use `cpu_scaling_factor()` headroom in
`test_peer_spawns_and_cancels_service_subactor`'s `fail_after` to avoid
flaky timeouts on throttled CI runners. Rename `arbiter_addr=` ->
`registry_addrs=[..]` throughout `test_spawning` and
`test_task_broadcasting` suites to match the current `open_root_actor()`
/ `open_nursery()` API.
