Event on linux i was noticing lotsa false negatives based on sub
teardown race conditions, so this tries to both make way for
(eventually?) expanding the set of suite cases and ensure the current
ones are more reliable on every run.
The main change is to hange the `error_in_child=False` case to use
parent-side-cancellation via a new `trio.move_on_after(timeout)` instead
of `actor.cancel_soon()` (which is now toggled by a new `self_cancel:
bool` but unused rn), and add better teardown assertions.
Low level deats,
- add `rent_cancel`/`self_cancel` params to
`crash_and_clean_tmpdir()` for different cancel paths;
default to `rent_cancel=True` which just sleeps forever
letting the parent's timeout do the work.
- use `trio.move_on_after()` with longer timeouts per
case: 1.6s for error, 1s for cancel.
- use the `.move_on_after()` cancel-scope to assert `.cancel_called`
pnly when `error_in_child=False`, indicating we
parent-graceful-cancelled the sub.
- add `loglevel` fixture, pass to `open_nursery()`.
- log caught `RemoteActorError` via console logger.
- add `ids=` to parametrize for readable test names.

Add a 6s timeout guard around `test_streaming_to_actor_cluster()`
to catch hangs, and nest the `async with` block inside it.
Found this when running `pytest tests/ --tpt-proto uds`.

Deliver `(LinkedTaskChannel, Any)` instead of the prior `(first, chan)`
order from `open_channel_from()` to match the type annotation and be
consistent with `trio.open_*_channel()` style where the channel obj
comes first.
- flip `yield first, chan` -> `yield chan, first`
- update type annotation + docstring to match
- swap all unpack sites in tests and examples

Convert every remaining `to_trio`/`from_trio` fn-sig style
to the new unified `chan: LinkedTaskChannel` iface added in
prior commit (c46e9ee8).
Deats,
- `to_trio.send_nowait(val)` (1st call) -> `chan.started_nowait(val)`
- `to_trio.send_nowait(val)` (subsequent) -> `chan.send_nowait(val)`
- `await from_trio.get()` -> `await chan.get()`
Converted fns,
- `sleep_and_err()`, `push_from_aio_task()` in
`tests/test_infected_asyncio.py`
- `sync_and_err()` in `tests/test_root_infect_asyncio.py`
- `aio_streamer()` in
`tests/test_child_manages_service_nursery.py`
- `aio_echo_server()` in
`examples/infected_asyncio_echo_server.py`
- `bp_then_error()` in `examples/debugging/asyncio_bp.py`
Also,
- drop stale comments referencing old param names.

With methods to comms similar to those that exist for the `trio` side,
- `.get()` which proxies verbatim to the `._to_aio: asyncio.Queue`,
- `.send_nowait()` which thin-wraps to `._to_trio: trio.MemorySendChannel`.
Obviously the more correct design is to break up the channel type into
a pair of handle types, one for each "side's" task in each event-loop,
that's hopefully coming shortly in a follow up patch B)
Also,
- fill in some missing doc strings, tweak some explanation comments and
update todos.
- adjust the `test_aio_errors_and_channel_propagates_and_closes()` suite
to use the new `chan` fn-sig-API with `.open_channel_from()` including
the new methods for msg comms; ensures everything added here works e2e.
Reorganize existing msg-related test suites under
a new `tests/msg/` subdir (matching `tests/devx/`
and `tests/ipc/` convention) and add unit tests for
the `_`-prefixed field filtering in `pformat()`.
Deats,
- `git mv` `test_ext_types_msgspec` and `test_pldrx_limiting` into
`tests/msg/`.
- add `__init__.py` + `conftest.py` for the new test sub-pkg.
- add new `test_pretty_struct.py` suite with 8 unit tests:
- parametrized field visibility (public shown, `_`-private hidden,
mixed)
- direct `iter_struct_ppfmt_lines()` assertion
- nested struct recursion filtering
- empty struct edge case
- real `MsgDec` via `mk_dec()` hiding `_dec`
- `repr()` integration via `Struct.__repr__()`

It seems something is up with their VM-img or wtv bc i keep increasing
the subproc timeout and nothing is changing. Since i can't try
a `-xlarge` one without paying i'm just muting this test for now.
- convert all doc-strings to `'''` multiline style.
- rename `nursery` -> `an`, `n` -> `tn` to match
project-wide conventions.
- add type annotations to fn params (fixtures, test
helpers).
- break long lines into multiline style for fn calls,
assertions, and `parametrize` decorator lists.
- add `ids=` to `@pytest.mark.parametrize`.
- use `'` over `"` for string literals.
- add `from typing import Callable` import.
- drop spurious blank lines inside generators.

Via ensuring `all(mark.args)` on wtv expressions are arg-passed to the
mark decorator; use it to skip the `test_subactor_breakpoint` suite when
`ctlc=True` since it seems too unreliable in CI.
There's a very sloppy registrar-actor-bootup syncing approach used in
this fixture (basically just guessing how long to sleep to wait for it
to init and bind the registry socket) using a `global _PROC_SPAWN_WAIT`
that needs to be made more reliable. But, for now i'm just playing along
with what's there to try and make less CI runs flaky by,
- sleeping *another* 1s when run from non-linux CI.
- reporting stdout (if any) alongside stderr on teardown.
- not strictly requiring a `proc.returncode == -2` indicating successful
graceful cancellation via SIGINT; instead we now error-log and only
raise the RTE on `< 0` exit code.
* though i can't think of why this would happen other then an
underlying crash which should propagate.. but i don't think any test
suite does this intentionally rn?
* though i don't think it should ever happen, having a CI run
"error"-fail bc of this isn't all that illuminating, if there is
some weird `.returncode == 0` termination case it's likely not
a failure?
For later, see the new todo list; we should sync to some kind of "ping"
polling of the tpt address if possible which is already easy enough for
TCP reusing an internal closure from `._root.open_root_actor()`.
Namely, after trying to get `test_multi_daemon_subactors` to work for
the `ctlc=True` case (for way too long), give up on that (see
todo/comments) and skip it; the normal case works just fine. Also tweak
the `test_ctxep_pauses_n_maybe_ipc_breaks` pattern matching for
non-`'UDS'` per the previous script commit; we can't use UDS alongside
`pytest`'s tmp dir generation, mega lulz.
To be a null default and set to `0.1` when not passed by the caller so
as to avoid having to pass `0.1` if you wanted the
param-defined-default.
Also,
- in the `spawn()` fixtures's `unset_colors()` closure, add in a masked
`os.environ['NO_COLOR'] = '1'` since i found it while trying to debug
debugger tests.
- always return the `child.before` content from `assert_before()`
helper; again it comes in handy when debugging console matching tests.
Improve the `spawn` fixture teardown logic in
`tests/devx/conftest.py` fixing the while-else bug, and fix
`test_advanced_faults` genexp for `TransportClosed` exc type
checking.
Deats,
- replace broken `while-else` pattern with direct
`if ptyproc.isalive()` check after the SIGINT loop.
- fix undefined `spawned` ref -> `ptyproc.isalive()` in
while condition.
- improve walrus expr formatting in timeout check (multiline
style).
Also fix `test_ipc_channel_break_during_stream()` assertion,
- wrap genexp in `all()` call so it actually checks all excs
are `TransportClosed` instead of just creating an unused
generator.

Adjust `basic_echo_server()` default sequence len to avoid the race
where the 'tell_little_bro()` finished streaming **before** the
echo-server sub is cancelled by its peer subactor (which is the whole
thing we're testing!).
Deats,
- bump `rng_seed` default from 50 -> 100 to ensure peer
cancel req arrives before echo dialog completes on fast hw.
- add `trio.sleep(0.001)` between send/receive in msg loop on the
"client" streamer side to give cancel request transit more time to
arrive.
Also,
- add more native `tractor`-type hints.
- reflow `basic_echo_server()` doc-string for 67 char limit
- add masked `pause()` call with comment about unreachable
code path
- alphabetize imports: mv `current_actor` and `open_nursery`
below typed imports

Add `TransportClosed` to except clauses where `trio`'s own
resource-closed errors are already caught, ensuring our
higher-level tpt exc is also tolerated in those same spots.
Likely i will follow up with a removal of the `trio` variants since most
*should be* caught and re-raised as tpt-closed out of the `.ipc` stack
now?
Add `TransportClosed` to various handler blocks,
- `._streaming.MsgStream.aclose()/.send()` except blocks.
- the broken-channel except in `._context.open_context_from_portal()`.
- obvi import it where necessary in those ^ mods.
Adjust `test_advanced_faults` suite + exs-script to match,
- update `ipc_failure_during_stream.py` example to catch
`TransportClosed` alongside `trio.ClosedResourceError`
in both the break and send-check paths.
- shield the `trio.sleep(0.01)` after tpt close in example to avoid
taskc-raise/masking on that checkpoint since we want to simulate
waiting for a user to send a KBI.
- loosen `ExceptionGroup` assertion to `len(excs) <= 2` and ensure all
excs are `TransportClosed`.
- improve multi-line formatting, minor style/formatting fixes in
condition expressions.

Refine tpt-error reporting to include closure attribution (`'locally'`
vs `'by peer'`), tighten match conditions and reduce needless newlines
in exc reprs.
Deats,
- factor out `trans_err_msg: str` and `by_whom: str` into a `dict`
lookup before the `match:` block to pair specific err msgs to closure
attribution strings.
- use `by_whom` directly as `CRE` case guard condition
(truthy when msg matches known underlying CRE msg content).
- conveniently include `by_whom!r` in `TransportClosed` message.
- fix `'locally ?'` -> `'locally?'` in send-side `CRE`
handler (drop errant space).
- add masked `maybe_pause_bp()` calls at both `CRE` sites (from when
i was tracing a test harness issue where the UDS socket path wasn't
being cleaned up on teardown).
- drop trailing `\n` from `body=` args to `TransportClosed`.
- reuse `trans_err_msg` for the `BRE`/broken-pipe guard.
Also adjust testing, namely `test_ctxep_pauses_n_maybe_ipc_breaks`'s
expected patts-set for new msg formats to be raised out of
`.ipc._transport`.

Convert `spawn` fixture to a generator and add post-test graceful
subproc cleanup via `SIGINT`/`SIGKILL` to avoid leaving stale `pexpect`
child procs around between test runs as well as any UDS-tpt socket files
under the system runtime-dir.
Deats,
- convert `return _spawn` -> `yield _spawn` to enable
post-yield teardown logic.
- add a new `nonlocal spawned` ref so teardown logic can access the last
spawned child from outside the delivered spawner fn-closure.
- add `SIGINT`-loop after yield with 5s timeout, then
`SIGKILL` if proc still alive.
- add masked `breakpoint()` and TODO about UDS path cleanup

Turns out we aren't clearing the `._state._runtime_vars` entries in
between `open_root_actor` calls.. This test refinement catches that by
adding runtime-vars asserts on the expected root-addrs value; ensure
`_runtime_vars['_root_addrs'] ONLY match the values provided by the
test's CURRENT root actor.
This causes a failure when the (just added)
`test_non_registrar_spawns_child` is run as part of the module suite,
it's fine when run standalone.
Ensure non-registrar root actors can spawn children and that
those children receive correct parent contact info. This test
catches the bug reported in,
https://github.com/goodboy/tractor/issues/410
Add new `test_non_registrar_spawns_child()` which spawns a sub-actor
from a non-registrar root and verifies the child can manually connect
back to its parent using `get_root()` API, auditing
`._state._runtime_vars` addr propagation from rent to child.
Also,
- improve type hints throughout test suites
(`subprocess.Popen`, `UnwrappedAddress`, `Aid` etc.)
- rename `n` -> `an` for actor nursery vars
- use multiline style for function signatures

Test pkg-level init module and sub-pkg module logger naming
to better validate auto-naming logic.
Deats,
- create `pkg_init_mod` and write `mod_code` to it for
testing pkg-level `__init__.py` logger instance creation.
* assert `snakelib.__init__` logger name is `proj_name`.
- write `mod_code` to `subpkg/__init__.py`` as well and check the same.
Also,
- rename some vars,
* `pkg_mod` -> `pkg_submod`,
* `pkgmod` -> `subpkgmod`
- add `ModuleType` import for type hints
- improve comments explaining pkg init vs first-level
sub-module naming expectations.
- drop trailing whitespace and unused TODO comment
- remove masked `breakpoint()` call

Add assertions and comments to better test the reworked
implicit module-name detection in `get_logger()`.
Deats,
- add `assert not tractor.current_actor()` check to verify
no runtime is active during test.
- import `.log` submod directly for use.
- add masked `breakpoint()` for debugging mod loading.
- add comment about using `ranger` to inspect `testdir` layout
of auto-generated py pkg + module-files.
- improve comments explaining pkg-root-log creation.
- add TODO for testing `get_logger()` call from pkg
`__init__.py`
- add comment about first-pkg-level module naming.

Use new implicit module-name detection throughout codebase to simplify
logger creation and leverage auto-naming from caller mod .
Main changes,
- drop `name=__name__` arg from all `get_logger()` calls
(across 29 modules).
- update `get_console_log()` calls to include `name='tractor'` for
enabling root logger in test harness and entry points; this ensures
logic in `get_logger()` triggers so that **all** `tractor`-internal
logging emits to console.
- add info log msg in test `conftest.py` showing test-harness
log level
Also,
- fix `.actor.uid` ref to `.actor.aid.uid` in `._trace`.
- adjust a `._context` log msg formatting for clarity.
- add TODO comments in `._addr`, `._uds` for when we mv to
using `multiaddr`.
- add todo for `RuntimeVars` type hint TODO in `.msg.types` (once we
eventually get that all going obvi!)
