Behaviour identical — the one-shot's result/error is awaited

First test-file of the #477 `.run_in_actor()` removal (blocking
`to_actor.run()` is the successor; the legacy non-blocking one-shot
is dropped, not replaced). All 9 call-sites migrated,
- blocking result/error/streaming-result tests -> `to_actor.run(fn,
an=an, ...)`; the "streaming" ones stream aio<->trio INSIDE the
subactor so the caller only awaits the final result.
- forever-task + cancel tests (`test_tractor_cancels_aio`,
`test_trio_cancels_aio`) -> `start_actor()` +
`Portal.open_context()` + cancel — can't block on a
never-returning task. Adds a small `sleep_forever_aio_ctx`
`@context` shim.
- greens the red `test_tractor_cancels_aio` anti-hang guard from
the prior commit: under the correctly-scoped API the wait is
bounded by the caller's cancel scope, so the hang is structurally
gone — not patched.

Wrap `test_tractor_cancels_aio`'s `main()` in a
`trio.fail_after(9 * cpu_perf_headroom())` so a wedged remote
runtime can't hang the test forever. This is the blessed
anti-hang guard here bc `pytest-timeout`'s global cap is
intentionally off (it breaks `trio` under the fork backends,
per the `pyproject` NOTE).
The cap is generous + CPU-headroom-scaled bc it's an anti-hang
guard, not a perf assertion. Motivated by the
`._ria_nursery`-removal regression where a wedged ria-reaper
once hung this exact test indefinitely.

This closes the checkpoint-free completion race without a

Resolve#474 with a new `tests/trionics/test_taskc.py` (9
tests) covering the `trio.Nursery.start()` wrapper landed in
PR #464, incl. the `modden.runtime.progman.open_wks()` use
case dug out as a minimal repro.
Deats,
- the lossy `RuntimeError('child exited without calling

its ambient cancel pre-`.started()` (graceful-teardown
pattern); a well-behaved child surfaces `Cancelled` direct
from `.start()` on `trio` 0.29 - verified empirically 1st.
- `test_sibling_err_not_masked_by_startup_rte`: the `modden`
case; ONLY the root-cause sibling `ValueError` escapes the
nursery with the wrapper vs. bare-`.start()`'s lossy
riding-along startup-RTE noise.
- `test_pure_oob_cancel_not_morphed_to_rte`: plain ancestor
`cs.cancel()` exits clean vs. bare's eg-wrapped RTE.
- `test_genuine_startup_rte_still_raised`: sans cancellation
the protocol-bug RTE re-raises same as bare.
- `test_childs_own_rte_never_demoted_to_cancel`: exact-msg +
`isinstance`-guard regression cover; a child's own
`RuntimeError('never got started!')`/`RuntimeError(1234)`
never demotes to a `Cancelled`.
- `test_started_value_and_args_passthru`: positional args,
`name=` and `.started()`-value forwarding.
Also,
- `use_start_or_cancel=False` params pin upstream `trio`'s
current lossy behaviour as wart-documentation: a break on
a `trio` upgrade likely means new upstream porcelain and
the wrapper deserves a re-audit.

Copilot's 2nd-pass review (PR #468) caught a regression I landed in
the uds fix: `UDSAddress.get_random()` put the per-call token AFTER
`@{pid}` (`no_runtime_*@{pid}.{token}.sock`), which breaks the
`tractor._testing._reap` matcher
`^(?P<name>.+)@(?P<pid>\d+)\.sock$` — so no-runtime orphan socks
stopped matching and never got reaped/attributed. Move the token
INTO the name (`{prefix}.{token}@{pid}.sock`) so the canonical
`@{pid}.sock` suffix stays intact for both that regex and the
`spawn._reap` reconstruction; also bump the token to 8 hex chars.
Also two robustness nits from the same review,
- `tests.conftest._measure_sustained_headroom()`: guard `frac <= 0`
before `1./frac` — a 0/parked-core freq read would
`ZeroDivisionError`, get swallowed by the broad `except` into a
1.0 (no-throttle), defeating the probe on the exact broken box it
should flag; read 0 as max throttle.
- `scripts/cpu-perf-check`: mark the burn procs `daemon=True` and
wrap sampling in `try/finally` so a Ctrl-C / error reaps them
instead of leaving stray CPU hogs.

noisy CPU load + needless memory across N procs. Mask each step to
64-bit for a steady, fixed-width ALU burn (still pegs every core,
which is all the freq probe needs).
Also, `_read_mhz()` opened the sysfs freq files without a ctx-mgr;

`uds_transport_actor_tree.py` (new in 759d46dd) reliably fails on

can't be pinned from CI logs; needs a macOS box to root-cause.

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.

(cherry picked from commit c07cf2546b)
A `trio.Nursery.start()`-style wrapper around
`trio.run_process()` that surfaces rc!=0 errors
deterministically, ALWAYS isolates the parent
controlling-tty, and optionally live-relays the child's
std-streams to `log.<level>` per-line. Suits both
short-lived test-runners + long-lived daemons.
`supervise_run_process()`,
- Deterministic rc!=0: pass `check=False` to `trio`
and do our OWN post-drain rc-check from the
supervisor coro body AFTER `own_tn.__aexit__` — NOT
inside the internal nursery, since that would
race-cancel the still-draining relay reader and lose
stderr lines. (Re)build + raise a BARE
`subprocess.CalledProcessError`: `.stderr=` for
programmatic callers + an `add_note()`'d
`|_.stderr:` block for human teardown logs. No
nursery-eg-wrapped CPE to `collapse_eg` around.
- Parent controlling-tty isolation: `stdin=DEVNULL`
always, `stdout=DEVNULL` unless relayed/overridden
(via `stdout=` kwarg w/ `_UNSET` sentinel so explicit
`None` = inherit still works). Prevents a spawned
program from clobbering the launching tty's scrollback
w/ control-seqs.
- Live per-line relay: `relay_stdout=True`/
`relay_stderr=True` → relayed to `log.<relay_level>`
(default `'io'`, our custom level 21). Picked to sort
just above stdlib `INFO`=20 so it shows at usual
`info`/`devx` levels yet stays separately filterable;
`runtime`=15 was REJECTED as a default since it'd be
silently filtered at usual verbosity — footgun for
daemon supervisors whose whole point is visibility.
STREAMED, not buffered-until-exit.
- Non-blocking `tn.start()` semantics: live
`trio.Process` handed up via
`task_status.started()` immediately (else
`tn.start()` would block till child exit, losing
the long-lived-daemon use case). Supervise/relay bg
tasks run to completion in this coro.
- `**run_process_kwargs` forwarded verbatim (env, shell,
cwd, start_new_session, executable, ...); MANAGED keys
(`stdin`/`stdout`/`stderr`/`check`) win on conflict.
- Crash-handling layer intentionally NOT baked in —
compose `maybe_open_crash_handler()` ON TOP at the
call-site.
`_relay_stream_lines()` helper,
- Concurrent pipe-drain reader. MANDATORY whenever piping
w/o `capture_*` since nothing else drains the OS pipe —
child blocks on `write()` once kernel buf (~64KiB) fills
→ deadlock.
- Modes (combine freely): `emit`-only live relay,
`accum`-only silent drain+capture (for the CPE note),
or both. Per-line splitting handles cross-chunk
residuals + flushes any trailing un-newline-term'd line
at EOF.
`_add_stderr_note()` helper,
- Attaches an indented `|_.stderr:` note to a CPE via
`add_note()` for legible rc!=0 reporting at teardown.
Tests (`tests/trionics/test_subproc.py`),
- Hermetic `trio`-only (no actor-runtime).
- `test_stdout_relayed_per_line`: per-line stdout relay.
- `test_parent_tty_isolated`: child fd1 is OUR pipe (no
`/dev/pts/*`), fd0 pinned to `/dev/null`.
- `test_no_deadlock_on_big_unnewlined_output`: 200KiB
no-newline output completes under `fail_after(2)` —
exercises the concurrent drain (without it, the child
blocks at ~64KiB).
- `test_stderr_relay_and_cpe_rebuild`: rc!=0 w/
`relay_stderr=True` → bare `CalledProcessError` w/ the
`.stderr` note + per-line live relay.
- `test_nonrelay_cpe_note`: rc!=0 w/o relay → same
deterministic post-drain CPE w/ `.stderr` note (silent
drain+capture path).
Re-export `supervise_run_process` from `tractor.trionics`.

Make the sub-actor proc-title prefix a single
authoritative constant (`_proctitle._def_prefix`) so
the reap-recognition markers and `xontrib` banner pick
it up automatically — one place to flip the prefix
shape going fwd.
Deats,
- `_proctitle._def_prefix: str = '_subactor'`. New
module-level const consumed by everything that needs
to know the prefix.
- `set_actor_proctitle(actor, prefix=_def_prefix)`:
takes an explicit `prefix` arg (default = the const)
so callers can override per-spawn if they want.
- Default proc-title format:
`'tractor[<reprol>]'` → `f'{prefix}[<reprol>]'`
i.e. `_subactor[<reprol>]` by default.
- `_testing/_reap.py`: cmdline + comm markers source
the prefix from `_proctitle._def_prefix` instead of
the hardcoded `'tractor['`. So
`_is_tractor_subactor()` tracks the const
automatically.
- `xontrib/tractor_diag.xsh`: `acli.reap` orphan-mode
banner now interpolates the
`_TRACTOR_PROC_CMDLINE_MARKERS` tuple directly so
the human-readable mode line stays in sync if the
prefix shape changes again.

Follow-up to f595acc7 (`supervise_run_process`) which
called `log.io(...)` for std-stream relay assuming an
`IO=21` level existed. Add the registration via a new
factory + tests covering both the factory and the new
level.
`add_log_level()` factory,
- One call wires the four (otherwise hand-synced) pieces:
- `CUSTOM_LEVELS[NAME]` — drives the `stacklevel` bump
in `StackLevelAdapter.log()` + `get_logger()`'s
per-level audit.
- `logging.addLevelName()` — stdlib name registration.
- `STD_PALETTE[NAME]` + `BOLD_PALETTE['bold'][NAME]` —
color entries consumed by `get_console_log()`'s
`ColoredFormatter` build.
- Same-named (lowercase) emit method bound on
`StackLevelAdapter` so `log.<name>('msg')` works +
`get_logger()`'s per-level method audit passes.
- Idempotent: re-registering an existing name is a
no-op-ish refresh that won't clobber an already-bound
method.
- Method binding uses a default-arg `_level=value` so
the level int is captured (not late-bound across
multiple registrations).
`IO=21` level (first user),
- Purple. Used by `tractor.trionics._subproc`'s
std-stream relay (see f595acc7).
- Value 21 picked to sit just ABOVE stdlib `INFO`=20 so
it's SHOWN BY DEFAULT at usual `info`/`devx` console
levels — a `runtime`=15 relay would be silently
filtered (footgun for daemon supervisors whose whole
point is visibility). Still distinctly labeled +
filterable.
Tests (`tests/test_log_sys.py`),
- `test_io_custom_level_registered`: validates the IO
level is fully wired (`CUSTOM_LEVELS`, `addLevelName`,
both palettes, `StackLevelAdapter.io()` callable);
emits a record + sanity-asserts `21 >= INFO(20)`.
- `test_add_log_level_pluggable`: registers a fresh
`XLVL=19` (cyan) via `add_log_level()`, asserts all
four wires + the bound `xlog.xlvl()` emit, then
try/finally cleans up the module-global mutations so
later `get_logger()` audits don't trip on a
half-removed level.

The `cpu_scaling_factor()` CI bump (2x) wasn't enough for the
macOS runners — slower + noisier than linux for our multi-actor
cancel-cascade timing — so `test_nested_multierrors[depth=3]` and
`test_fast_graceful_cancel_*` flaked there (linux + sdist green),
- make the CI headroom platform-aware: 3x on macOS, 2x on linux
(keeps the proven linux budget; depth=3 inner 12*3=36s still
fits under the 40s outer wall).
- give `test_fast_graceful_cancel_*` the `cpu_scaling_factor()`
headroom it was missing entirely (was a bare `timeout=2.9`).
Verified locally w/ `CI=1` (2x linux path; 3x macOS path confirmed
via forced `_non_linux`).

All 5 flagged items were valid (4 real bugs + 1 dead assert),
- fix an inverted `sys.version_info < (3, 14)` guard in
`ipc._linux` — the "`cffi` has no 3.14 support" import note now
fires on 3.14+ (where it applies) instead of on older pys.
- use `os.environ.get('PYTHON_COLORS')` in the `sync_bp` example
so it doesn't `KeyError` when run outside the test harness.
- correct `dump_task_tree()`'s docstring: the `/tmp` + `/dev/tty`
tee is gated on `write_file`/`write_tty`, not "unconditional".
- tidy the `ActorTooSlowError` message spacing in `cancel_actor`.
- replace a tautological `applied is True or applied is False` in
`test_patches` with `isinstance(applied, bool)` (the value is
order-dependent across the module).

GH Actions (and most shared) CI runners are slow + noisy and —
unlike a throttled local box — don't expose CPU-freq scaling via
sysfs, so `cpu_scaling_factor()` read `1.0` and the timing-
sensitive deadlines/asserts that key off it got NO headroom on
CI (a class of `TooSlowError` / `assert diff < this_fast` flakes),
- add a flat `_ci_env` x2 bump inside `cpu_scaling_factor()` so
every test already using it (quad streaming, SIGINT-cancel,
docs examples, ...) gets CI headroom for free — compounds with
any local-throttle factor.
- route the `time_quad_ex` cancel-deadline through it instead of
a bespoke per-test `ci_env` bump.
- fix a real bug in `test_nested_multierrors`: its OUTER
`@tractor_test(timeout=10)` was *smaller* than the inner
`fail_after_w_trace` budget (trio depth=3 = 12s), so the outer
wall fired first and pre-empted the snapshot-capturing inner
deadline -> `FAILED` instead of dumping. Bump the outer to `40`
(> max inner budget) and scale the inner budgets by
`cpu_scaling_factor()` too.
Verified locally with `CI=1` (quad + both `test_nested_multierrors`
depths + `test_cancel_via_SIGINT_other_task` green).

Same trio 0.29 → 0.33 cancel-cascade slowdown that hit
`test_nested_multierrors` (ea67f1b6) — bumps the
`trio`-backend (non-debug, non-forking) budget in
`test_echoserver_detailed_mechanics` from 1s → 4s.
- The 1s budget raced the ~1s teardown deadline. On a
deadline-fire trio 0.33 injects
`Cancelled(source='deadline')` (cancel-reason
metadata) that wraps the mid-stream KBI in a
`BaseExceptionGroup`, breaking the bare
`pytest.raises(KeyboardInterrupt)` below.
- Bump matches the forking-spawner branch (4s).

trio 0.29 → 0.33 lock bump (c7741bba) slowed the

(cherry picked from commit 57b3ea59ea)
Strip the trailing `pkg_path` token ONLY when it duplicates the
caller's leaf-*module* name (which the console header already
shows via `{filename}`), instead of blindly dropping the last
token. This keeps genuine, possibly-*nested* sub-PACKAGE parts
addressable as their own sub-loggers.
- detect a true leaf-mod by comparing the caller's `__name__`
vs `__package__` (a pkg `__init__` has them equal -> its
trailing token is a real sub-pkg, NOT a leaf to strip).
- `name='devx.debug'` now -> `tractor.devx.debug`, DISTINCT
from a bare `devx` -> `tractor.devx`; the old unconditional
`pkg_path = subpkg_path` collapsed both to `tractor.devx` and
silently broke per-sub-pkg level control via the logging-spec.
- `get_logger(__name__)` leaf-strip still works (cosmetic, bc
the leaf-mod is in the `{filename}` header field).
Also,
- update the `LogSpec` caveat: sub-PACKAGE granularity now
addressable at ANY depth; leaf *modules* intentionally aren't
(they're the `{filename}`); top-level mods (eg. `to_asyncio`)
still emit on the root logger.
- adjust `test_root_pkg_not_duplicated_in_logger_name` to the
new literal explicit-`name` contract (no leaf-collapse).

(cherry picked from commit 9c36363b01)
Two coupled changes that let downstream projects (eg. `modden`) inherit
the test-harness loglevel plumbing for free via
`tractor._testing.pytest`:
Plugin lift (`tests/conftest.py` → `_testing/pytest.py`),
- mv `pytest_addoption(--ll)`, the `loglevel` autouse
fixture, and `test_log` fixture out of the test-suite-
local conftest into the reusable plugin.
- add `--tl`/`--tractor-loglevel` as a DISTINCT flag from
`--ll`: `--ll` is the consuming-project's OWN app
loglevel (scoped to its pkg-hierarchy), `--tl` is the
`tractor.*` runtime loglevel. `--tl` falls back to
`--ll` when unset (preserves current `tractor`-suite
behavior).
- add `testing_pkg_name` session fixture (default
`'tractor'`) — downstream projects override to e.g.
`'modden'` so `--ll` scopes to their own hierarchy
instead of `tractor.*`.
- `loglevel` fixture now yields the resolved
tractor-runtime level (passed to
`open_root_actor(loglevel=<.>)` by `@tractor_test`)
AND separately applies `--ll` to the
`testing_pkg_name` hierarchy when that isn't
`tractor`. `test_log` scopes the per-test logger to
`testing_pkg_name`.
`tractor.log` "logging-spec" mini-DSL,
- `LogSpec = str|bool`. Accepted forms:
- `True` → enable `pkg_name` root at `default_level`
(fallback `'cancel'`).
- `False` → no-op.
- bare level eg. `'info'` → root-logger at that level.
- `'sub:info,x:cancel'` → per-sub-logger filter-spec;
each `<name>` is RELATIVE to `pkg_name` (must NOT
include the pkg-token).
- `parse_logspec()` → `{sublog|None: level}` mapping.
`None` key = root-logger. Mixed bare-level + filters
in one spec is rejected w/ a helpful err msg; so is
embedding the `pkg_name` token in a sub-name.
- `apply_logspec()` → `(primary_level, {name: log})`:
parses then enables a `colorlog` stderr handler per
named (sub)logger. Authoritative sub-logger filters
get `propagate=False` so they don't double-emit
through a parallel root-level handler.
- !GRANULARITY CAVEAT! sub-logger names match at
sub-pkg granularity, not leaf-module — so `devx.debug`
collapses to the same `tractor.devx` logger as a bare
`devx`, and top-level lib modules (eg.
`tractor.to_asyncio`) emit under the *root* logger
rather than a phantom `to_asyncio` child. Documented
inline on `LogSpec`.
Other,
- `tests/conftest.py` keeps a NOTE pointing to the
plugin for future-debugging clarity (don't remove
silently — the lift is the relevant signal).

Adopt the `_testing.trace` CM helpers in two MTF-hang-prone
tests so on-timeout we get a fresh
`ptree`/`wchan`/`py-spy` diag snapshot on disk instead of
opaque pytest timeout-kills. Same shape as bd07a95d for
`test_dynamic_pub_sub`.
Deats,
- `test_echoserver_detailed_mechanics`:
* inner `trio.fail_after` → `fail_after_w_trace`. Adds
`fail_after_w_trace: FailAfterWTraceFactory` fixture
param.
* mv per-backend `timeout` calc to top of test body (was
interleaved w/ helper defs).
* factor deep
`open_nursery`/`open_context`/`open_stream` body into
`_body()` so the wrapping `main()` stays a 2-liner —
keeps the nested-CM block at its natural indent level
instead of pushing it under yet another `async with`.
* drop `with_timeout: bool` knob + `fa_main()` helper
(knob was hard-coded `True`).
- `test_sigint_closes_lifetime_stack`:
* outer `signal.alarm`/`try`/`finally` → single
`afk_alarm_w_trace(10)` CM. Adds
`afk_alarm_w_trace: AfkAlarmWTraceFactory` fixture
param.
* drop `_AFK_CAP_S` + `armed_alarm` vars (CM owns both).
* explanatory comment refreshed to mention
`AFKAlarmTimeout` + the disk-snapshot side effect.
Other,
- Drop debug `return 1e3` short-circuit from `delay()`
fixture — snuck in as a scratch line, was clobbering the
proper `debug_mode`-branched return.

same-name spawning against a forkserver + registrar
— the `wait_for_peer_or_proc_death` helper now surfaces
the death instead of parking forever on the handshake
wait.
Also,
- extract inline `xfail` into module-level
`_DOGGY_BOOT_RACE_XFAIL` marker.
- apply it to `n_dups=8` too (previously bare) bc
larger N widens the race window enough to fire
occasionally.
- link to tracking issue #456.
