In top level `daemon`-fixture that is..
Use a local `bg_daemon_spawn_delay` instead of
mutating the module-level `_PROC_SPAWN_WAIT` —
previously each `daemon` fixture invocation would
permanently add 1.6s (UDS) or 1s (CI) to the
global, inflating delays across the session.
Also, emit a `test_log.warning()` when verbose
loglevel is silently reduced to `'info'`.

(cherry picked from commit c4885f9d99)
With a seminal patch fixing `trio`'s `WakeupSocketpair.drain()` which
can busy-loop due to lack of handling `EOF`.
New `tractor.trionics.patches` subpkg housing defensive monkey-patches
for upstream `trio` bugs we've encountered while running `tractor`
— particularly as of recent, fork-survival edge cases that haven't been
filed/fixed upstream yet. Each patch is idempotent, version-gated via
`is_needed()`, and carries a `# REMOVE WHEN:` marker pointing at the
upstream release whose adoption allows deletion.
Subpkg layout + per-patch contract documented in
`tractor/trionics/patches/README.md` — `apply()` / `is_needed()`
/ `repro()` API, registry pattern via `_PATCHES` in `__init__.py`,
single-call entry point `apply_all()`.
First patch, `_wakeup_socketpair`:
- `trio`'s `WakeupSocketpair.drain()` loops on `recv(64KB)` and exits
ONLY on `BlockingIOError`, NEVER on `recv() == b''` (peer-closed FIN).
- under `fork()`-spawning backends the COW-inherited socketpair fds
& `_close_inherited_fds()` teardown can leave a `WakeupSocketpair`
instance whose write-end is closed, and `drain()` then **spins forever
in C with no Python checkpoints**,
- this obviously burns 100% CPU and no signal delivery.
Standalone repro:
from trio._core._wakeup_socketpair import WakeupSocketpair
ws = WakeupSocketpair()
ws.write_sock.close()
ws.drain() # spins forever
Patch is one-line — break the drain loop on b'' EOF.
Manifested as two distinct test failures:
- `tests/test_multi_program.py::test_register_duplicate_name` hung at
100% CPU on the busy-loop directly (fork child's worker thread)
- `tests/test_infected_asyncio.py::test_aio_simple_error` Mode-A
deadlock — busy-loop wedged trio's scheduler inside `start_guest_run`,
both threads parked in `epoll_wait`, no TCP connect-back to parent
ever happened.
Same patch fixes both. Restored 99.7% pass rate on full
suite under `--spawn-backend=main_thread_forkserver`
(was hanging indefinitely before).
Wired into `tractor._child._actor_child_main` via `apply_all()` BEFORE
any trio runtime init. Harmless on non-fork backends.
Conc-anal write-ups, including strace + py-spy evidence:
- `ai/conc-anal/trio_wakeup_socketpair_busy_loop_under_fork_issue.md`
- `ai/conc-anal/infected_asyncio_under_main_thread_forkserver_hang_issue.md`
Regression tests in `tests/trionics/test_patches.py`: each test asserts
(a) the bug exists pre-patch (or is fixed upstream — skip cleanly), (b)
the patch fixes it with a SIGALRM wall-clock cap so a regression hangs
loud instead of silently.
TODO:
- [ ] file the upstream `python-trio/trio` issue + PR.
- [ ] use the `repro()` callable in `_wakeup_socketpair.py` IS the issue
body's evidence section.

(cherry picked from commit 0ef549fadb)
(factored: dropped spawn-backend-only paths: ai/conc-anal/infected_asyncio_under_main_thread_forkserver_hang_issue.md)
In `tests/devx/conftest.py::spawn`, refactor the
fixture-internal closures so consumer tests can pass
explicit `start_method`/`loglevel` to each `_spawn()`
invocation rather than only inheriting the fixture-
scoped parametrize values.
Deats,
- promote `set_spawn_method()` and `set_loglevel()`
to take their respective values as fn params (vs
closing over the fixture-scope vars).
- give `_spawn()` `start_method=start_method` and
`loglevel: str|None = None` kwargs so callers
override one-off without re-parametrizing the
suite. NOTE: this drops the implicit fixture-
scoped `loglevel` forward — `_spawn()` callers
now must pass `loglevel=...` explicitly.
- TODO: figure out how `--ll <level>` should map to
the default (currently `None` → uses env-var or
tractor default).
- add a docstring to `_spawn()` so its role as the
consumer-facing closure is obvious from `help()`.
Also,
- `assert_before()` now returns the `.before` output
on success (was `None`); add a one-line docstring
describing the new return contract.

(cherry picked from commit 486249d74f)
Add env-var overrides inside `._root.open_root_actor()` so
devs/test-runs can swap the actor-spawn backend or crank
console verbosity *without* touching application code.
In `._root.open_root_actor()`,
- read `TRACTOR_LOGLEVEL` early, overriding any caller-passed
`loglevel` and stashing an `env_ll_report` to emit once the
console log is set up.
- pull the `loglevel` fallback (`or _default_loglevel`) and
`log.get_console_log()` init *up* so the env-var report
routes through tractor's own logger.
- read `TRACTOR_SPAWN_METHOD`, overriding any caller-passed
`start_method` and warn-logging when the env-var clobbers
an explicit caller value.
Wire the same vars through `tests/devx/conftest.py::spawn`,
- request the `loglevel` fixture, set both `TRACTOR_LOGLEVEL`
and `TRACTOR_SPAWN_METHOD` in `os.environ` before each
`pexpect.spawn()` (inherited by the example subproc).
- expand `supported_spawners` to include
`main_thread_forkserver` and `subint_forkserver` bc
example scripts no longer need per-script CLI plumbing.
- pop both vars in fixture teardown so a leaked value can't
re-route a later in-process tractor test's spawn-backend
or loglevel.

(cherry picked from commit 208e7c0926)
Two version-compat fixes for the `devx` debugger
test-suite, both about matching upstream output that
got more verbose w/ recent lib releases.
ANSI stripping (`tests/devx/conftest.py`),
- Add `ansi_strip(text)` helper + `_ansi_re` pattern
(regex per https://stackoverflow.com/a/14693789).
- Apply inside `in_prompt_msg()` + `assert_before()` so
substring matches against REPL/traceback output stay
robust to color leakage.
- Motivated by py3.13's colored tracebacks +
`pdbp`/pygments highlighting leaking ANSI even when
`PYTHON_COLORS=0` is set in the `spawn` fixture (not
every renderer in the spawned subproc honors it).
- Replaces the longstanding inline TODO that linked
the SO answer w/o impl'ing.
trio 0.30+ `Cancelled._create(` match (`test_debugger`),
- In `test_shield_pause` swap the two
`"raise Cancelled._create()"` assertion patterns →
`"raise Cancelled._create("` (open-paren form, no
closing).
- trio >=0.30 raises a multi-line
`raise Cancelled._create(source=.., reason=..,
source_task=..)` w/ cancel-reason metadata, so the
legacy bare-`()` form no longer matches. Inline
comment documents the trio-version pivot.

Since we're devving subints we require the 3.14+ stdlib API
and a couple compiled libs don't support it yet, namely:
- `cffi`, which we're only using for the `.ipc._linux` eventfd
stuff (now factored into `hotbaud` anyway).
- `greenback`, which requires `greenlet` which doesn't seem to be
wheeled yet
* on nixos the sdist build was failing due to lack of `g++` which
i don't care to figure out rn since we don't need `.devx` stuff
immediately for this subints prototype.
* [ ] we still need to adjust any dependent suites to skip.
Adjust `test_ringbuf` to skip on import failure.

- drop `msgspec>=0.20.0`, the first release with py3.14 support.

Provide a service-table parsing API for downstream projects (like
`piker`) to declare per-actor transport bind addresses as a config map
of actor-name -> multiaddr strings (e.g. from a TOML `[network]`
section).
Deats,
- `EndpointsTable` type alias: input `dict[str, list[str|tuple]]`.
- `ParsedEndpoints` type alias: output `dict[str, list[Address]]`.
- `parse_endpoints()` iterates the table and delegates each entry to the
existing `tractor.discovery._discovery.wrap_address()` helper, which
handles maddr strings, raw `(host, port)` tuples, and pre-wrapped
`Address` objs.
- UDS maddrs use the multiaddr spec name `/unix/...` (not tractor's
internal `/uds/` proto_key)
Also add new tests,
- 7 new pure unit tests (no trio runtime): TCP-only, mixed tpts,
unwrapped tuples, mixed str+tuple, unsupported proto (`/udp/`),
empty table, empty actor list
- all 22 multiaddr tests pass rn.

Add 9 test variants (6 fns) covering all three
`tpt_bind_addrs` code paths in `open_root_actor()`:
- registrar w/ explicit bind (eq, subset, disjoint)
- non-registrar w/ explicit bind (same/diff
bindspace) using `daemon` fixture
- non-registrar default random bind (baseline)
- maddr string input parsing
- registrar merge produces union
- `open_nursery()` forwards `tpt_bind_addrs`
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

Move the subprocess probe into dedicated spawn test support files so the inheritance tests cover the real __main__ replay path without monkeypatching or inline script strings.
Clean up mutable defaults, give parent-main bootstrap data a named type, and add direct start_actor coverage so the opt-out change is clearer to review.
Use `inherit_parent_main` across the actor APIs and helper to better describe the behavior, and restore the reviewer note at child bootstrap where the inherited `__main__` data is copied from `SpawnSpec`.
Keep actor-owned parent-main capture and let `_mp_figure_out_main()` decide whether to return `__main__` bootstrap data, avoiding the extra SpawnSpec plumbing while preserving the per-actor flag.
Keep trio child bootstrap data in the spawn handshake instead of stashing it on Actor state so the replay opt-out stays explicit and avoids stale-looking runtime fields.
Let actor callers skip replaying the parent __main__ during child startup so downstream integrations can avoid inheriting incompatible bootstrap state without changing the default spawn behavior.
The per-`ctx_key` locking fix in f086222d intended to resolve the
teardown race reproduced by the new test suite, so the test SHOULD now
pass. TLDR, it doesn't Bp
Also add `collapse_eg()` to the test's ctx-manager stack so that when

`test_discovery`, `test_multi_program`).
- update "arbiter" -> "registrar" in comments/docstrings
across `_discovery.py`, `_server.py`, `_transport.py`,
`_testing/pytest.py`, and examples.
- drop resolved TODOs from `_runtime.py` and `_root.py`.

Adjust all `tractor._state`, `tractor._addr`,
`tractor._supervise`, etc. refs in tests and examples
to use the new `runtime/`, `discovery/`, `spawn/` paths.
Also,
- use `tractor.debug_mode()` pub API instead of
`tractor._state.debug_mode()` in a few test mods
- add explicit `timeout=20` to `test_respawn_consumer_task`
`@tractor_test` deco call

- Use `bidict.forceput()` in `register_actor()` to handle
duplicate addr values from stale entries or actor restarts.
- Fix `uid` annotation to `tuple[str, str]|None` in
`maybe_open_portal()` and handle the `None` return from
`delete_addr()` in log output.
- Pass explicit `registry_addrs=[reg_addr]` to `open_nursery()`
and `find_actor()` in `test_stale_entry_is_deleted` to ensure
the test uses the remote registrar.
- Update `query_actor()` docstring to document the new
`(addr, reg_portal)` yield shape.

By spawning an actor task that immediately shuts down the transport
server and then sleeps, verify that attempting to connect via the
`._discovery.find_actor()` helper delivers `None` for the `Portal`
value.
Relates to #184 and #216
- `test_inter_peer_cancellation`: swap all `.uid` refs
on `Actor`, `Channel`, and `Portal` to `.aid.uid`
- `test_legacy_one_way_streaming`: same + fix `print()`
to multiline style

Use 6s timeout on non-linux (vs 4s) in
`test_cancel_while_childs_child_in_sync_sleep()` to avoid
flaky `TooSlowError` on slower CI runners.

Removes the `pytest` deprecation warns and attempts to avoid
some de-registration raciness, though i'm starting to think the
real issue is due to not having the fixes from #366 (which handle
the new dereg on `OSError` case from UDS)?
- use `.channel.aid.uid` over deprecated `.channel.uid`
throughout `test_discovery.py`.
- add polling loop (up to 5s) for subactor de-reg check
in `spawn_and_check_registry()` to handle slower
transports like UDS where teardown takes longer.
